MySQL 33 - Datetime, Date, Time Data Types
 
06:40
Next up on our MySQL to-do list is to learn about storing dates and times. There are various data types in MySQL for storing dates and times. It seems MySQL and databases likes to break everything up into multiple data types to make things more organized at the consequence of being confusing and annoying. This video is going to be talking about the DATETIME, DATE, and TIME data types. These are all used to store, you guessed it, dates and times. The one you choose depends on your needs. If you just need dates, choose DATE. If you just need times, choose TIME, if you need both stored together, choose DATETIME. Now you set a column one of these data types whenever you want every row for this field to have some sort of date, time or both…but how exactly is the data formatted? This requires us to understand some convention. For example, in the USA at least, if you have something like 4:30AM, by convention you know the hour is 4 and the minutes are 30. But this is just an agreed upon convention. MySQL has its own convention…For example 2017-02-02. The first thing is the year, the second is the month, and the third is the day. That is for the DATE. The convention for time is 22:54:30. The first is the hour (military time), the second is the minute, and the third is the seconds. Lastly, there can actually be fractions of seconds…up to microseconds! .123456. To use fractional seconds though you must specify to MySQL the precision of the TIME or DATETIME when you create it, for example DATETIME(6) would allow microsecond precision. How do you actually give a date to MySQL? By that I mean let's say you have a table with a column of DATETIME(6), and you want to give a value for that column, how do you format it? It's quoted. For example: '2017-02-02 22:54:30.333333' MySQL interprets this as a DATETIME. ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ Support me! http://www.patreon.com/calebcurry Subscribe to my newsletter: http://bit.ly/JoinCCNewsletter Donate!: http://bit.ly/DonateCTVM2. ~~~~~~~~~~~~~~~Additional Links~~~~~~~~~~~~~~~ More content: http://CalebCurry.com Facebook: http://www.facebook.com/CalebTheVideoMaker Google+: https://plus.google.com/+CalebTheVideoMaker2 Twitter: http://twitter.com/calebCurry Amazing Web Hosting - http://bit.ly/ccbluehost (The best web hosting for a cheap price!)

MySQL 24 - Important Data Types
 
05:33
I decided that instead of going through all of the categories of data types real slow, I'm going to give you a video that gives you the most important data types. That way, you can have a pretty good idea of what data types you need to use and when. Also, if any of the info in this video is too fast, you can watch the next videos to get a more in depth understanding. The first data type is CHAR. This data type stores a string that is of a fixed length. You will only want to use this when you know the length of the data for the column. For example, you might have a column for phone numbers. As long as you know that every phone number is going to be the same format, you could use a column with the CHAR data type. You would just specify it as CHAR(length). VARCHAR works in a similar fashion to CHAR, but it works best for variable length data. That means that if you have a column where each row is going to have a different length, you would want to use VARCHAR. For example, if you had a column for an email address, each email is going to be any number of characters. Now, we are going to be going into numeric data types. For each of the numeric data types there are two variations. Signed and unsigned. Signed data types allow for negative values, but the highest value will be lower. Unsigned do not allow negatives but can store higher positive numbers. INT is the data type you use when you need whole numbers. This is likely going to be the data type used for ID columns. DOUBLE is the data type that can be used when you need to store a real number. This means that there can be numbers after a decimal point. There is also a data type called FLOAT. This works similarly but cannot handle as many numbers after the decimal. These data types have the downside in that they often cannot be trusted when doing math. Only use DOUBLES for data where it is acceptable to be pretty close to correct. DECIMAL is a datatype that can be used for numbers where precision is extremely important. For example, Decimal can be used for columns dealing with money, important measurements, or anything where we need the data to work 100% as expected in arithmetic. TIMESTAMP is a column that is used to easily record an instance in time. This is often used to record when row is created or updated. That's because it will automatically generate a value when an INSERT or UPDATE is issued against the database. DATE, DATETIME, and TIME are all used to store dates and times. There are some differences between these and a TIMESTAMP, but I'll just give you one for now to tease you To understand the differences between these and the timestamp, you need to understand something known as UTC time. UTC time is a standard that you can compare against all time zones. It is known as coordinated universal time. So for example, PST is 8 hours behind UTC. The different between TIMESTAMP and these is that TIMESTAMP will convert whatever value to UTC when stored, and convert it back to whatever your time zone is when you retrieve it. This means that if you want to store a date that is going to change to the users time zone when retrieved, use TIMESTAMP. If it needs to stay the same no matter what, use DATETIME. If that's not super clear, we'll try to discuss it in more detail in an upcoming video. The goal of this video was not to teach you the intimate details on defining data types. The goal was to give you a rough over view of the main data types you will find in MySQL. ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ Support me! http://www.patreon.com/calebcurry Subscribe to my newsletter: http://bit.ly/JoinCCNewsletter Donate!: http://bit.ly/DonateCTVM2. ~~~~~~~~~~~~~~~Additional Links~~~~~~~~~~~~~~~ More content: http://CalebCurry.com Facebook: http://www.facebook.com/CalebTheVideoMaker Google+: https://plus.google.com/+CalebTheVideoMaker2 Twitter: http://twitter.com/calebCurry Amazing Web Hosting - http://bit.ly/ccbluehost (The best web hosting for a cheap price!)

MySQL 31 - DECIMAL Data Type
 
02:20
The DECIMAL data type is similar to the INT data type in that when you use the number for math, it maintains precision. The difference though is obvious in the name. The DECIMAL data type allows for numbers after a decimal point (and before the decimal point). The DECIMAL data type allows us to store what is known as a fixed-point number. A fixed point number is a number that has a specific number of digits available to store numbers in. That means we can't do things like use a DECIMAL data type to store as many digits of PI as possible, because we can't store unlimited digits. We are limited to a certain number. There are two keywords you need to understand when you are working with the DECIMAL data type, precision and scale. Precision is the number of digits and scale is the number of those digits that will come after the radix. You are going to want to provide these numbers when you declare a column of this data type. For example, DECIMAL(5, 2) has a precision of 5 digits and a scale of 2 digits. That means we can store a maximum of two digits after the decimal and four digits total. This gives us a possible range from -999.99 to 999.99 The highest number of digits is 65, and the highest number of digits after the decimal is 30. This data type is also known as DEC, NUMERIC, and FIXED. ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ Support me! http://www.patreon.com/calebcurry Subscribe to my newsletter: http://bit.ly/JoinCCNewsletter Donate!: http://bit.ly/DonateCTVM2. ~~~~~~~~~~~~~~~Additional Links~~~~~~~~~~~~~~~ More content: http://CalebCurry.com Facebook: http://www.facebook.com/CalebTheVideoMaker Google+: https://plus.google.com/+CalebTheVideoMaker2 Twitter: http://twitter.com/calebCurry Amazing Web Hosting - http://bit.ly/ccbluehost (The best web hosting for a cheap price!)

MySQL 32 - FLOAT and DOUBLE Data Types
 
06:23
FLOAT and DOUBLE data types are data types that can be used to store numbers that can include decimal numbers. They are specifically used to store estimates. What do I mean? I mean that the precision of a FLOAT or DOUBLE value can be lost when doing math. The data types are only capable of maintaining a certain level of precision. The level of precision is usually adequate for most mathematical operations. If you need to store exact data, you will want to look into using the INT or DECIMAL data type instead. The numbers stored in a FLOAT or DOUBLE column are called floating point numbers, we'll see why in just a moment. Why are they called floating point numbers? let's look at a number. 150. This number could be represented as 150, or it could be represented as 1.5 * 10^2, or 1.5e2. With floating point numbers, scientific notation is used. These numbers are called floating point numbers because the decimal can float to different spots as we change the exponent. This means that the data type needs to store the number, how many decimal the number needs moved, and a sign bit. The benefit of floating point numbers is that they allow us to store pretty huge numbers. The down side is that they are not storing values exactly because they are limited in size. This means that only a certain level of precision is to be expected from a floating point data type. If you remember from the video of DECIMAL, precision is the number of digits in a number. As long as the precision for one of these data types exceeds the need for your specific data, the data type can work fine. For example, if you are storing a number like 15 trillion, you don't have to worry as much with precision as your number does not contain a lot of digits. This number can be represented as 1.5 x 10^13. This is a lot different than trying to store 1.5534534534 x10^13. Now we know both of these data types do not maintain a high number of digits correctly, but what is the difference between FLOAT and DOUBLE. The difference is the amount of storage they take up. Float takes up 4 bytes while DOUBLE takes up 8. The benefit in DOUBLE is that because it has more room to store data, it has a higher level of precision and can store bigger numbers. Now, what level of precision can you expect from either of these? FLOAT around 7 and DOUBLE around 15. Now, these data types are obnoxious because the exact values depend on your operating system and in general these monsters cannot be trusted. Especially when you start doing math with different numbers. In general, it is recommended to use the DOUBLE data type to have a higher level of precision and calculations in MySQL are done with DOUBLE. Always remember… prepare for trouble, make it double. ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ Support me! http://www.patreon.com/calebcurry Subscribe to my newsletter: http://bit.ly/JoinCCNewsletter Donate!: http://bit.ly/DonateCTVM2. ~~~~~~~~~~~~~~~Additional Links~~~~~~~~~~~~~~~ More content: http://CalebCurry.com Facebook: http://www.facebook.com/CalebTheVideoMaker Google+: https://plus.google.com/+CalebTheVideoMaker2 Twitter: http://twitter.com/calebCurry Amazing Web Hosting - http://bit.ly/ccbluehost (The best web hosting for a cheap price!)

Oracle DB Vs MySQL for Enterprise DataBase Deployments
 
08:54
Oracle DB is big, and expensive, but it brings a lot to the "table" when compared with MySQL. MySQL has limited ability to audit. MySQL's security is unsophisticated. There are no groups or roles, no ability to deny a privilege (you can only grant privileges). A user who logs in with the same username and password from different network addresses may be treated as a completely separate user. There is no built-in encryption comparable to Oracle. MySQL's Authentication is built-in. There is no LDAP, Active Directory, or other external authentication capability. MySQL has no MPP (massively parallel processing ) support. Unlike Oracle MySQL has no fractional-second storage type for times, dates, or intervals. There is no RAC (Real Application Cluster) support in My SQL, and no failover or server promotion either. These are strong features in Oracle MySQL's number of joins per query is limited to 61. Oracle's limit is much larger. MySQL Replication is asynchronous and has many limitations and edge cases. For example, it is single-threaded, so a powerful slave can find it hard to replicate fast enough to keep up with a less powerful master.

MySQL 27 - TEXT, TINYTEXT, MEDIUMTEXT, LONGTEXT
 
03:42
The TEXT data types have not yet been discussed, but they are another string data type. They are similar to the VARCHAR data type with some minor differences that are important to know. The first thing to note is that there are four versions used to determine different sizes. From least to greatest size is TINYTEXT, TEXT, MEDIUMTEXT, LARGETEXT. These each have different maximum byte sizes: 255, 65535, 16 million something, and 4 billion something. You create a column as one of these data types just as you would with a varchar column. You work with them exactly the same, too. If that is the case, what are the primary differences between these and VARCHAR? The first difference is that VARCHAR is restricted by the row limit of a table. TEXT tables do not contribute nearly as much (max of 12 bytes) because the data is not stored inline in the table. This means that if you need to allow for extra space for other rows, you can use a TEXT column. And even though the table only contains a pointer to the data, it is all hidden to us and working with a TEXT column is the same as working with a VARCHAR column. The second primary difference is that TEXT data types do not allow for a default other than NULL. Thirdly, VARCHAR is limited to just under 64KB, whereas you can use MEDIUMTEXT or LARGETEXT to allow for more storage. So if what you are trying to store as an individual value is over 64KB, use a text column. Other than those three things, VARCHAR will usually work just fine for our text needs. Now, last thing is that these data types are often called CLOB data types. ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ Support me! http://www.patreon.com/calebcurry Subscribe to my newsletter: http://bit.ly/JoinCCNewsletter Donate!: http://bit.ly/DonateCTVM2. ~~~~~~~~~~~~~~~Additional Links~~~~~~~~~~~~~~~ More content: http://CalebCurry.com Facebook: http://www.facebook.com/CalebTheVideoMaker Google+: https://plus.google.com/+CalebTheVideoMaker2 Twitter: http://twitter.com/calebCurry Amazing Web Hosting - http://bit.ly/ccbluehost (The best web hosting for a cheap price!)

MySQL 30 - INT Data Type
 
03:02
The last section of videos covered the string data types, now we are going to move on to the numeric data types. This video is going to discuss the INTEGER data types, or the INT data types. These data types are used to store whole numbers. That is, numbers without anything after a decimal. Just like with the TEXT data type, INT is broken up into multiple data types that can be used. It is actually broken up into 5 different data types. TINYINT, SMALLINT, MEDIUMINT, INT, BIGINT. Now, the confusing part here is the naming. That's because the only thing we have to compare this naming to is the TEXT data types. But they don't follow a consistent naming convention. For example, MEDIUMTEXT is larger than TEXT, but MEDIUMINT is smaller than INT. Additionally, there are 5 data types for the INT data type group, and lastly the biggest INT data type is called BIGINT whereas the biggest TEXT data type is called LONGTEXT. These are used to store exact values. What that means is that if you store a number and use it, you expect it to maintain precision. There are data types that are used for estimated values which we are going to discuss in more detail in an upcoming video. For now, let's focus on INT data types. You can find the exact storage limits for each of these, but here is some info: TINYINT - 255 SMALLINT - 65535 MEDIUMINT - 16 Million INT - 4 Billion BIGINT - Stinkin' a lot (18446744073709551615) Now note, in this situation, we will have to label each one of these as UNSIGNED. An unsigned number does not allow for negatives, but allows higher positive numbers. You can look up the INT data types to get the exact ranges for signed and unsigned. ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ Support me! http://www.patreon.com/calebcurry Subscribe to my newsletter: http://bit.ly/JoinCCNewsletter Donate!: http://bit.ly/DonateCTVM2. ~~~~~~~~~~~~~~~Additional Links~~~~~~~~~~~~~~~ More content: http://CalebCurry.com Facebook: http://www.facebook.com/CalebTheVideoMaker Google+: https://plus.google.com/+CalebTheVideoMaker2 Twitter: http://twitter.com/calebCurry Amazing Web Hosting - http://bit.ly/ccbluehost (The best web hosting for a cheap price!)

Explore the full course on Udemy (special discount included in the link): https://www.udemy.com/the-ultimate-hands-on-hadoop-tame-your-big-data/?couponCode=HADOOPUYT Choosing the right database for your application is no easy task. You have a wide variety of options relational databases such as MySQL, or distributed NoSQL solutions such as MongoDB, Cassandra, and HBase. NoSQL has come to mean not only SQL as many distributed database systems do in fact support SQL-style queries, as long as you are not doing complex join operations and this further blurs the lines between these systems. We will talk about how to analyze the requirements of your system in terms of consistency, availability, and partition-tolerance, and how to apply the CAP theorem to guide your choice after showing you where different database technologies fall on the sides of the CAP triangle. We will also talk about more practical considerations, such as your budget, need for professional support, and the ease of integration into the other systems already in place in your organization. Maybe you dont even need a distributed storage solution at all! Choosing the right technology for your data storage will save you a lot of pain as your application grows and evolves and making the wrong choice can lead to all sorts of maintenance problems and wasted work. Your instructor is Frank Kane of Sundog Education, bringing nine years of experience as a senior engineer and senior manager at Amazon.com and IMDb.com, where his job involved extracting meaning from their massive data sets, and processing that data in a highly distributed manner.

MySQL 26 - VARCHAR Data Type
 
04:29
Varchar is very similar to CHAR in that it is used to store strings, but there are some pretty big differences. The first difference is that when you store data less than the max it does not pad it with spaces to make it fit. The benefit in this is that you will save storage. The downside to this is that now MySQL is going to have to keep track of how many characters you have. To do this, each value is going to have an additional byte or two that MySQL can use. The max length is 65535 bytes. That is per value in that column! But you have to keep in mind encodings. If your characters are encoded with something such as UTF-8, each character can take up multiple bytes. The max size for a character in this case is 3 bytes. That means that we really can't store that many characters. Additionally, MySQL has a row limit of 65535 bytes (potential bytes…meaning declared sizes). What does this mean? It means that if you make this too big, you are not going to be able to create other columns. Earlier I said that there will be an additional byte or two for each value you put into this column. The purpose of this is to keep track of how long the string is. Why one or two and not one? The reason being is because with one byte we can only count to 255. if we want to keep track of bytes after that we need two bytes. This means that we actually can't store quite 65535 bytes. Realistically, we can't store that much because we have to store the length of the string, and each character can take up to 3 bytes which can push us over the row limit. This means the real max is a little less than a third of that. Not every character is going to take up 3 bytes, but MySQL assumes it will as to not cut you short. This is slightly different than CHAR because char you can store up to 255 characters, not bytes. Even if you use an encoding where some characters take up multiple bytes, you can still store 255 of them. Remember that reason for this is that VARCHAR is subject to the row-limit. MySQL will not let you go past the max and will tell you the appropriate max, so don't worry about it too much. You should try not to push your limits. Plus, most of the time you will not come even close to the max for most columns. Should you use the max? Varchar will only store what is needed to store a value, but you should still try to have the max size no more than what is needed. ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ Support me! http://www.patreon.com/calebcurry Subscribe to my newsletter: http://bit.ly/JoinCCNewsletter Donate!: http://bit.ly/DonateCTVM2. ~~~~~~~~~~~~~~~Additional Links~~~~~~~~~~~~~~~ More content: http://CalebCurry.com Facebook: http://www.facebook.com/CalebTheVideoMaker Google+: https://plus.google.com/+CalebTheVideoMaker2 Twitter: http://twitter.com/calebCurry Amazing Web Hosting - http://bit.ly/ccbluehost (The best web hosting for a cheap price!)

MySQL 25 - CHAR Data Type
 
04:47
The first category of data types that we are going to cover in this MySQL series are the string data types, or character data types. There are two that I am going to talk about in this video, CHAR and VARCHAR. We'll start with CHAR. CHAR is a string data type where you specify how many characters are allowed in parenthesis after you declare the column as this type. For example, we can say CHAR(50) to allow up to 50 characters for each value in that column. The thing to know about CHAR though is that it is a fixed-length string. That means every single value inside of that column is actually going to be whatever you declare the length as. So if you say CHAR(50), every string is going to be 50 characters long. If, for example, you have a row that only uses 40 characters, MySQL will pad the right side of the string with spaces until it fills 50 characters. Now, the highest value you can put in here is 255. The 255 refers to characters. This means that you can have strings with up to 255 characters. How does the computer know how to store these characters? That has to deal with the character set and the encoding of the characters. By default, MySQL is going to use UTF-8. We are not going to discuss UTF-8 in detail for a while but essentially UTF-8 says that each character can take up to 3 bytes of storage. 255 comes from the max number you can count to using binary. So if we are keeping track of how many values are in this column in an 8 bit number, 255 is the highest. If you don't know what I'm talking about it, we'll worry about it later. You can actually make the column CHAR(0). In this situation, the only thing you could put in as a value for this column is an empty string (''). When retrieving variable length CHAR data from a database it may not look like the database pads the value. That's because MySQL actually strips spaces from the value when presented. If you want to keep all of the spaces that have been added when you retrieve the value, you can do that. Look up PAD_CHAR_TO_FULL_LENGTH online. In the next video we are going to discuss VARCHAR. ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ Support me! http://www.patreon.com/calebcurry Subscribe to my newsletter: http://bit.ly/JoinCCNewsletter Donate!: http://bit.ly/DonateCTVM2. ~~~~~~~~~~~~~~~Additional Links~~~~~~~~~~~~~~~ More content: http://CalebCurry.com Facebook: http://www.facebook.com/CalebTheVideoMaker Google+: https://plus.google.com/+CalebTheVideoMaker2 Twitter: http://twitter.com/calebCurry Amazing Web Hosting - http://bit.ly/ccbluehost (The best web hosting for a cheap price!)

Replicate from Oracle to Oracle, Oracle to MySQL, and Oracle to Analytics
 
59:02
Oracle is the most powerful DBMS in the world. However, Oracle's expensive and complex replication makes it difficult to build highly available applications or move data in real-time to data warehouses and popular databases like MySQL. In this webinar you will learn how Continuent Tungsten solves problems with Oracle replication at a fraction of the cost of other solutions and with less management overhead too -- think "Oracle GoldenGate without the price tag!" We will demo constructing a highly available site using Oracle-to-Oracle replication. We will then show you how to replicate data in real time from Oracle to MySQL as well as load a data warehouse.

Combining the Power of SQL and NoSQL Databases with MySQL
 
38:51
SQL has served IT for 30 years now and is far from being obsolete. In recent years NoSQL databases have emerged due to different needs of the developer. While offering the benefit of storing different data structures almost every NoSQL engine has adopted SQL or an SQL-like query language back into the engine. There are advantages on both sides but how can one combine the power of SQL and NoSQL into one database? We will answered that question in MySQL 5.7 with a set of new features for storing unstructured data in JSON. Out of the box MySQL now supports a JSON data type, a set of functions for manipulating JSON data, and the ability to query JSON using the power of SQL. Indexing is also supported via the addition of generated columns. It is now possible to combine the benefits of the schema and schemaless NoSQL world, and this session will explain the benefits to each approach. Morgan Tocker MySQL Senior Product Manager Oracle
