Table Shrinking in Oracle Database
 
14:15
1.Shrink the Table: Shrinking is started from 10g. In this method I’m using user u1 and table name sm1. Now I’m deleting some rows in sm1 COUNT ---------- 1048576 Table sm1 has 1048576 rows. [email protected]: delete from sm1 where deptno=10; 262144 rows deleted. I deleted above number of rows. Rows COUNT ---------- 786432 And I’m giving commit [email protected]: commit; Commit complete. So now we have 786432 rows in sm1 table. Now see the following command [email protected]: select OWNER,TABLESPACE_NAME,SEGMENT_NAME,SEGMENT_TYPE,BYTES/1024/1024||' mb'"space",BLOCKS,EXTENTS from dba_segments where tablespace_name like 'U%TS'; OWNER TABLESPACE_NAME SEGMENT_NAME SEGMENT_TYPE space BLOCKS EXTENTS ----- --------------- ------------- ------------- ------ ---------- ---------- U1 U1TS SM1 TABLE 29 mb 3712 44 After I deleted some rows in sm1 table still above result showing same values, so now our duty is shrink this table. This is done by following 2 ways, i By using COMPACT key word: In this method shrinking is done in two phases. In the first phase all fragmented space are just defragmented, but still the High Water Mark is persist with last used block only. That mean used free blocks are not de allocated and HWM is not updated here. Issue the following command before use shrink command. [email protected] alter table sm1 enable row movement; Table altered. There is particular use with above command, when we shrink the table all rows are moves to contiguous blocks, so here row movement should be done. By default the row movement is disabled for any table, so above command enabled the row movement. Then execute shrink command now. [email protected]: alter table sm1 shrink space compact; Table altered. Now see the space of table by using below command. [email protected]: select OWNER,TABLESPACE_NAME,SEGMENT_NAME,SEGMENT_TYPE,BYTES/1024/1024||' mb'"space",BLOCKS,EXTENTS from dba_segments where tablespace_name like 'U%TS'; OWNER TABLESPACE_NAME SEGMENT_NAME SEGMENT_TYPE space BLOCKS EXTENTS ----- --------------- ------------- ------------- ------ ---------- ---------- U1 U1TS SM1 TABLE 29 mb 3712 44 So here seems nothing happened with above shrink command, but internally the fragmented space is defragmented. But the high water mark is not updated, used free blocks are also not de allocated. For de allocating the used blocks we have to execute below command. This is the second phase. [email protected]: alter table sm1 shrink space; Table altered. Now see the space by using below command. [email protected]: select OWNER,TABLESPACE_NAME,SEGMENT_NAME,SEGMENT_TYPE,BYTES/1024/1024||' mb'"space",BLOCKS,EXTENTS from dba_segments where tablespace_name like 'U%TS'; OWNER TABLESPACE_NAME SEGMENT_NAME SEGMENT_TYPE space BLOCKS EXTENTS ----- --------------- ------------- ------------- ---------- ---------- ---------- U1 U1TS SM1 TABLE 20.8125 mb 2664 36 So now the space of sm1 table is reduced. Note: Actually the alter table sm1 shrink space command will complete these two phases of the shrinking of table at a time. But here we done shrink process in two phases because when we use alter table sm1 shrink space command the table locked temporarily some time period, during this period users unable to access the table. So if we use alter table sm1 shrink space compact command the table is not locked but space is defragmented. When we not in business hours issue the second phase shrink command then users are won’t get any problem. ii Because of above method the table dependent objects are goes to invalid state, to overcome this problem we have to use below command. [email protected]: alter table sm1 shrink space cascade; Table altered. The above command also shrinks the space of all dependent objects. We also do this in two phases like above two phases. See the below command. [email protected]: alter table sm1 shrink space compact cascade; Table altered. And then [email protected]: alter table sm1 shrink space cascade; Table altered.

SQLPLUS: LineSize & PageSize
 
03:49
In this tutorial, you'll learn how to set linesize and pagesize . PL/SQL (Procedural Language/Structured Query Language) is Oracle Corporation's procedural extension for SQL and the Oracle relational database. PL/SQL is available in Oracle Database (since version 7), TimesTen in-memory database (since version 11.2.1), and IBM DB2 (since version 9.7).[1] Oracle Corporation usually extends PL/SQL functionality with each successive release of the Oracle Database. PL/SQL includes procedural language elements such as conditions and loops. It allows declaration of constants and variables, procedures and functions, types and variables of those types, and triggers. It can handle exceptions (runtime errors). Arrays are supported involving the use of PL/SQL collections. Implementations from version 8 of Oracle Database onwards have included features associated with object-orientation. One can create PL/SQL units such as procedures, functions, packages, types, and triggers, which are stored in the database for reuse by applications that use any of the Oracle Database programmatic interfaces. PL/SQL works analogously to the embedded procedural languages associated with other relational databases. For example, Sybase ASE and Microsoft SQL Server have Transact-SQL, PostgreSQL has PL/pgSQL (which emulates PL/SQL to an extent), and IBM DB2 includes SQL Procedural Language,[2] which conforms to the ISO SQL’s SQL/PSM standard. The designers of PL/SQL modeled its syntax on that of Ada. Both Ada and PL/SQL have Pascal as a common ancestor, and so PL/SQL also resembles Pascal in several aspects. However, the structure of a PL/SQL package does not resemble the basic Object Pascal program structure as implemented by a Borland Delphi or Free Pascal unit. Programmers can define public and private global data-types, constants and static variables in a PL/SQL package.[3] PL/SQL also allows for the definition of classes and instantiating these as objects in PL/SQL code. This resembles usage in object-oriented programming languages like Object Pascal, C++ and Java. PL/SQL refers to a class as an "Abstract Data Type" (ADT) or "User Defined Type" (UDT), and defines it as an Oracle SQL data-type as opposed to a PL/SQL user-defined type, allowing its use in both the Oracle SQL Engine and the Oracle PL/SQL engine. The constructor and methods of an Abstract Data Type are written in PL/SQL. The resulting Abstract Data Type can operate as an object class in PL/SQL. Such objects can also persist as column values in Oracle database tables. PL/SQL is fundamentally distinct from Transact-SQL, despite superficial similarities. Porting code from one to the other usually involves non-trivial work, not only due to the differences in the feature sets of the two languages,[4] but also due to the very significant differences in the way Oracle and SQL Server deal with concurrency and locking. There are software tools available that claim to facilitate porting including Oracle Translation Scratch Editor,[5] CEITON MSSQL/Oracle Compiler [6] and SwisSQL.[7] The StepSqlite product is a PL/SQL compiler for the popular small database SQLite. PL/SQL Program Unit A PL/SQL program unit is one of the following: PL/SQL anonymous block, procedure, function, package specification, package body, trigger, type specification, type body, library. Program units are the PL/SQL source code that is compiled, developed and ultimately executed on the database. The basic unit of a PL/SQL source program is the block, which groups together related declarations and statements. A PL/SQL block is defined by the keywords DECLARE, BEGIN, EXCEPTION, and END. These keywords divide the block into a declarative part, an executable part, and an exception-handling part. The declaration section is optional and may be used to define and initialize constants and variables. If a variable is not initialized then it defaults to NULL value. The optional exception-handling part is used to handle run time errors. Only the executable part is required. A block can have a label. Package Packages are groups of conceptually linked functions, procedures, variables, PL/SQL table and record TYPE statements, constants, cursors etc. The use of packages promotes re-use of code. Packages are composed of the package specification and an optional package body. The specification is the interface to the application; it declares the types, variables, constants, exceptions, cursors, and subprograms available. The body fully defines cursors and subprograms, and so implements the specification. Two advantages of packages are: Modular approach, encapsulation/hiding of business logic, security, performance improvement, re-usability. They support object-oriented programming features like function overloading and encapsulation. Using package variables one can declare session level (scoped) variables, since variables declared in the package specification have a session scope.

This tutorial series is part of SQL expert exam certification training. if you are preparing for SQL certification you can use my tutorials. This SQL Tutorial is a part of free training. Copy Cloud referral link || Use this link to join copy cloud and get 20GB of free storage https://copy.com?r=j7eYO7 Contacts E-Mail [email protected] Twitter https://twitter.com/rebellionrider Instagram http://instagram.com/rebellionrider Facebook. https://www.facebook.com/imthebhardwaj Linkedin. http://in.linkedin.com/in/mannbhardwaj/ Thanks for linking, commenting, sharing and watching more of our videos This is Manish from RebellionRider.com Today in this oracle database tutorial we will see How to CREATE A TABLE. if we have to define a table in layman language then we can say that Tables are just a collection of Rows and Columns but In RDBMS tables are database objects which help in organizing data into ROWS and COLUMNS. We can also say that SQL tables are kind of data structure which are used by database for efficient storage of data. To create a table in our database we use SQL CREATE TABLE command. SQL CREATE TABLE is a type of DATA DEFINITION LANGUAGE also known as DDL. To Create a table in your schema you will require CREATE TABLE system privilege. In our future videos we will see what are system and object privileges and how to grant them to a user. Today for this video we will be using Sample schema HR which already has all the necessary privileges. Ohk Let's see the syntax. CREATE TABLE table name ( column name1 Data-Type(size), column name2 Data-Type(size), ..... ); CREATE TABLE is an oracle reserved word or say an Oracle key word whereas There are 3 different ways of creating a table in Oracle database. Creating a table using Command Line Interface (CLI) in Oracle database For demonstrating how to create table in oracle database using CLI, I'll be using Command prompt. Thats how we create table using command prompt. you can check your table structure by DESCRIBE command for that just write DESC and your table name. Like this Another way of creating a table is by using Graphic user interface (GUI) in Oracle database To demonstrate how to create table using GUI we will use SQL developer. Lets open our SQL developer I am connected to HR schema if you do not know how to create a connection to database using SQL developer please watch my oracle database tutorial 4 that explains database connectivity using SQL developer and command prompt. Link for this video is in the description below. So lets create a table. Creating a table using SQL developer is very easy we do not have to fire any query here. Let's start First of all right click on your connection in which you want to create a table and choose schema browser. This will open a separate schema browser pane or you can expend your connection by clicking this + sign and then right click on table and choose New Table. However I prefer working with schema browser so let's skip to schema browser pane here from the first drop-down list you can choose connection name and in the second drop down list you can choose what database objects you want to work with we want to create a table thus I'll choose table and then click this arrow here and choose option for new table Ok we have created a table wizard first of all give a unique name to your table and add some column as well. For this, click the green plus button. Now we already have a column so give it some name. Also choose a datatype from the list and specify any size you can check this not null column if in case you want to make this a mandatory column you can also specify default value and constraint If you want to make this column a primary key you can click here In my future video i'll show you what are these constraints and different ways of applying them on a column in a table. for this video we will concentrate on create table only so when you are done with all your columns click ok Thats your table You can double click on your table here and can see its structure. Thats it

Oracle SQL Tutorial 11 - CREATE TABLE
 
05:04
The way you create a table is to use the CREATE TABLE command. CREATE TABLE users() So in this situation, the name comes right after the TABLE keyword. The next thing we do is put all of the columns on a line that we want to put in our table. CREATE TABLE users( user_id, username, first_name, last_name ) Notice the naming conventions here. For this series we are going to make columns with what is known as snake casing. This is where each individual word is separated by an underscore. if you have more than one column, all of them have to have commas except the last one. The comma is a way to say that another column is coming, so you don't need to do it on the last one. Now you would think we were done, but we also have to say what data type each column is. Later we will extensively discuss data types so we can focus on them exclusively. For now, here are the data types we are going to use: CREATE TABLE users( user_id NUMBER, username VARCHAR2(50), first_name VARCHAR2(50), last_name VARCHAR2(50) ) Now, inside of the parenthesis for varchar2, we pass in a number... This is the max length of the string. But the question is, what is it measured in? The default is actually in bytes, not characters. For example if we have the string hello, it is 5 characters, but it might take up a total of 10 bytes of storage. So I would recommend adding the keyword char right after the number so it defaults to 50 characters, not bytes. CREATE TABLE users( user_id NUMBER, username VARCHAR(50 CHAR), first_name VARCHAR2(50 CHAR), last_name VARCHAR2(50 CHAR) ) This will work to create a table, but it's really missing a lot of information… which column is the primary key? Are we adding any indexes? Is there any thing else we need to say about these columns? So as you can tell, we are making progress, but there is still so much to learn. The biggest gotcha to remember from this video is that the data type VARCHAR ends in a 2, stupid, right? who would end the name of something with a 2?

SQL with Oracle 10g XE - Using ALTER TABLE to Modify Table Columns
 
05:23
In this video I use the ALTER TABLE command to modify an existing field column. The command will allow you to change the data types, whether the field can be null, or even the primary key. When using the ALTER TABLE command you would use the keyword MODIFY to make changes to an existing column. Be careful when changing a data type of the null field as existing data may cause an error if not in compliance with the new change. The code I used to alter the Books table is : ALTER TABLE BOOKS MODIFY ISBN_10 VARCHAR(13); This video is part of a series of videos with the purpose of learning the SQL language.

SQL functions are divided into two categories 1st is Single Row Functions And another one is Multiple row function which is also known as aggregate functions. But in today's SQL tutorial we will concentrate on Single Row Functions. Single-row functions operate on one row at a time and return one row of output for each input row. Single row functions are capable of manipulating data items and modifying the data types. Single row functions return one result per row and act on each row that is returned. Single row functions can accept one or more arguments and return one value. These arguments can be a column or an expression. With oracle we have 5 types of Single Row Functions 1. Character Functions 2. Number Functions 3. General Functions 4. Conversion Functions and 5. Date Functions. Character Functions are further divided into two categories. 1st is Case- manipulation functions and 2nd is Character Manipulation functions. We have 3 case manipulation functions Lower, upper and initcap and 7 character manipulation functions Sql functions concat, substr, length, instr, lpad, rpad, trim and replace. In our future video we will see what these functions are and what they do along with other SQL function. That's it for today's sql tutorial. Hope you enjoyed watching.

This command will also work on other versions of database like Oracle 11g Database, Oracle 10g Database, Oracle 9i Database, Oracle 8i Database, Oracle 8 Database and so on. Whenever you create a new table in oracle, you need to specify the columns and datatype and length of the table. But sometimes you need to create a table which is exactly same as the other table. you need the same structure as the other table have. So, in that case, you need not write the whole columns etc. This command will help you to do that. Full Syntax will be given in this video tutorial about how to create a table from another table in oracle database. Along with the live example to create the table from another table.

Table App Overview in Blackboard Web Community Manager
 
01:18
Tables are a way to arrange data in rows and columns to provide a visual representation of information. They can be simple, like a roster of students and corresponding grade levels. They can also be multi-dimensional, like a multiplication matrix where the intersection of the values in a column and row is the product of the row and column header values. Learn more: https://help.blackboard.com/Web_Community_Manager/Teacher_Editor/App_Showroom/Table_App Transcript: You can use tables to arrange data in rows and columns to provide a visual representation of information. Let’s take a look. The first time you edit the Table app, specify the number of rows and columns you want. The Table Size window shows the current size of your table and you can always add or remove rows and columns later. The Header Row checkbox will activate the first row as your header row. The Header Column checkbox will activate the first column as your header column. Expand Set Table Options - to add a Table Caption, and Table Summary – both of which comply with ADA requirements, and select a Table Style. When editing your table, select a cell to access the Insert Tool Bar – which allows for inserting an Image, an unordered list such as bullets, or a numbered list. Highlight text within a cell to access the Editor Tool Bar which allows for formatting, and text justification. And finally, the right-click menu includes the options to insert a row above or below; insert a column on the left or right; remove a row or column; undo and redo; and set cell content alignment. And that’s the Table App Overview. Thanks for watching!

A Story of Indexes and Full Table Scans: Finding All the Red Sweets Part 1
 
08:43
"Why isn't Oracle using my index?!" is a common question people have when tuning SQL queries. In this episode Chris compares two methods for finding all the red candies from party bags he's prepared. He shows how these are like a full table scan and an index range scan. He goes on to compare the performance of these two approaches. He shows when a full table scan becomes more efficient than an index range scan and vice versa. ============================ The Magic of SQL with Chris Saxon Copyright © 2015 Oracle and/or its affiliates.

MySQL Workbench Database Export and Import
 
08:08
Learn Database Export and Import using MySQL Workbench. Open MySQL Workbench and logged in to MySQL database server using 'root' username and password. In previous couple of videos we learned how to Create, Alter, Drop Databases and Tables and also how to Insert, Read, Update, Delete data rows using MySQL Workbench. In this lecture we will learn how to Export and Import the database using MySQL Workbench. First of all to Export the databases or tables, from top menu 'Server' select 'Data Export' Option, which opens a new window of data export settings and options. The left section on the window displays all the existing databases on our MySQL database server. When we select a database by clicking on it, it displays all the respected tables under the selected database. We can select one or multiple database check-boxes to include the database in the Export file. Under 'Export Options' section, You can change the default export path of you choice. I'll keep the default one. By selecting first option that is 'Export to Dump Project Folder'. MySQL Workbench will save the save all tables as separate SQL file under one folder. Which is useful when you will be importing or restoring the export file one by one table. I'll go ahead quickly and first save as 'Export to Dump Project Folder', MySQL Workbench displays the progress bar and log. Now, I'll again export the database using 'Export to Self-contained File' option. To demonstrate the import first I'll delete the existing 'students' table under 'mytestdb' database. Display database details by clicking on 'i' symbol, select 'tables' tab. Select and right click 'students' table, and click 'Drop Table' option, confirm and delete the table. Click 'refresh' to update the tables section and we have no table in our 'mytestdb' database. Now select the database and from 'data import' window, select 'import from dump folder. 'Load folder contents' and select only 'mytestdb' database and click start import button to import 'students' table again. Go to 'mytestdb' database information window again and click 'refresh' button to reload table list again. and the 'students' table is back.

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!)
