SQL: Change User Password
 
02:38
In this tutorial, you'll learn how to change user password in sql plus 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.

Oracle SQL Tutorial 22 - Why Primary Keys Shouldn't Change
 
07:14
In the last video I mentioned that with our database design it is important to make sure that nobody tries to update a user's username. What happens if they do? Nothing horrible, Oracle will just throw an error. That's not such a big deal, but if you are hoping to make some kind of application that allows someone to change their username, this is not the best set up. Why? If you look at the projects table, we have a foreign key that references the username. Let's assume for a moment that Oracle allows you to do anything with your data. That means that if a user updates their username, there will be projects created by users that don't exist. Or a user could change their name to the previous owner. To fix this problem, we would need something such as an ON UPDATE CASCADE command for our foreign key. That would mean that if the user updated their username, the columns that reference that username would also update to the new value. This exists in some database management systems, but this does not exist in Oracle at the time of this video. How do we get around this problem? I'm sure we could conjure up something to allow us to update the username, but the easiest solution is to reference the user_id instead of the username. That way, when the username is updated, nothing changes inside of the foreign key. As a general rule, primary keys should never change. Foreign keys CAN change, but they should not change because a primary key changed. So, if we did happen to use a username as a column, it would be frowned upon if the username had to change because the column it references changes. However, it would be acceptable to change the foreign key if we needed to point to a new entity in the users table. Even if a username is never intended to change, these complications bother a lot of people. You can mitigate these problems by only referencing surrogate keys in foreign keys. This has the downside though that when you retrieve the data, you are going to have to do more work to make the data readable. For example, we had a table that was called project_users. It is essentially a table that says what users are part of what projects. We could have the foreign keys reference the project's name and the user's username. Then when you could say SELECT * FROM project_users. The data would be completely readable without doing anything. If you switch to only referencing surrogate primary keys, you will have a bunch of random numbers that don't mean anything and will have to be joined with other tables…which is really super frustrating when later you have to join a thousand tables to read anything. Which side do you prefer? Pick a side. Choose wisely.

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

05 How to configure Sub partition using rang & list in oracle
 
16:31
You can create subpartitions in a composite partitioned table using a subpartition template. A subpartition template simplifies the specification of subpartitions by not requiring that a subpartition descriptor be specified for every partition in the table. Instead, you describe subpartitions only once in a template, then apply that subpartition template to every partition in the table. For interval-* composite partitioned tables, the subpartition template is the only way to define subpartitions for interval partitions. The subpartition template is used whenever a subpartition descriptor is not specified for a partition. If a subpartition descriptor is specified, then it is used instead of the subpartition template for that partition. If no subpartition template is specified, and no subpartition descriptor is supplied for a partition, then a single default subpartition is created. Specifying a Subpartition Template for a *-Hash Partitioned Table In the case of [range | interval | list]-hash partitioned tables, the subpartition template can describe the subpartitions in detail, or it can specify just the number of hash subpartitions. The following example creates a range-hash partitioned table using a subpartition template: CREATE TABLE emp_sub_template (deptno NUMBER, empname VARCHAR(32), grade NUMBER) PARTITION BY RANGE(deptno) SUBPARTITION BY HASH(empname) SUBPARTITION TEMPLATE (SUBPARTITION a TABLESPACE ts1, SUBPARTITION b TABLESPACE ts2, SUBPARTITION c TABLESPACE ts3, SUBPARTITION d TABLESPACE ts4 ) (PARTITION p1 VALUES LESS THAN (1000), PARTITION p2 VALUES LESS THAN (2000), PARTITION p3 VALUES LESS THAN (MAXVALUE) ); This example produces the following table description: Every partition has four subpartitions as described in the subpartition template. Each subpartition has a tablespace specified. It is required that if a tablespace is specified for one subpartition in a subpartition template, then one must be specified for all. The names of the subpartitions, unless you use interval-* subpartitioning, are generated by concatenating the partition name with the subpartition name in the form:

Checkpoint Revalidate
 
02:28
The REVALIDATE option regenerates the table headers for a partitioned table or uncompressed join index and optionally verifies and corrects the row partitioning for a table (but not for a join index) if you specify the WITH DELETE or WITH INSERT null partition handling options. You can specify the REVALIDATE option for unpartitioned tables and join indexes without also specifying PRIMARY INDEX. This makes revalidation applicable whether or not the table or join index has a primary index. You must specify the REVALIDATE option without also specifying PRIMARY INDEX for NoPI tables and column‑partitioned tables and join indexes. Otherwise, Teradata Database aborts the request and returns an error to the requestor. The REVALIDATE option also provides the ability to revalidate some data dictionary columns. REVALIDATE requests do not verify the column partitioning of a column‑partitioned table or join index. If partitioning errors are detected for a table (but not a join index), an ALTER TABLE REVALIDATE request corrects them. REVALIDATE also revalidates the following Data Dictionary table columns. wave web technology was established in 2012, and has a dynamic team of professional web developers, web designers, SEO experts and customer support . website : www.wavewebtech.com https://www.facebook.com/wavewebtechnologies https://twitter.com/wavewebtechnolo https://plus.google.com/collections/

SQL with Oracle 10g XE - Creating Calculated Columns with SELECT
 
05:06
In this video I create a calculated field based off the data from an existing column. When creating a calculated column you can use addition, subtraction, multiplication, and division. In the video I increased a column by 10 percent, decreased it by 15 percent and divided it in half. The results are not stored in the table, but are created on-the-fly. If you need parenthesis you can use them to change the order of operations in your math calculation. This video is part of a series of videos with the purpose of learning the SQL language.

The Oracle DROP TABLESPACE command is used to remove a tablespace from the database. In the following example, we will drop the USELESS tablespace from our database using the Oracle DROP TABLESPACE command: Drop tablespace useless; The Oracle DROP TABLESPACE command Oracle will generate an error if objects reside in the tablespace. Do the following to remove all objects in the tablespace prior to using Oracle DROP TABLESPACE command: Drop tablespace useless including contents; Oracle does not clean up after itself wile using the Oracle DROP TABLESPACE command by default. An option exists to force Oracle to clean up after itself using the Oracle DROP TABLESPACE command. The following example illustrates the Oracle DROP TABLESPACE command used with the including contents and datafiles keywords: Drop tablespace useless including contents and datafiles;

Learn How to Delete Data Rows using Delete Statement in SQL
 
03:39
In this lecture we will learn about using DELETE statement in SQL. As the name suggests DELETE statement is used to delete the data rows in a table. The DELETE statement can delete one or multiple data rows from a table. WHERE clause is used to specify the data row to be deleted. DELETE statement without WHERE clause will delete all the data rows in the table. Here are the examples DELETE statements, DELETE FROM tablename; DELETE FROM tablename WHERE column1 = value; Select the "school" database, "USE school;" Run a simple SQL statement to display all the data rows in students2 table using SQL statement, "SELECT * FROM students2;" Currently the 'students2' table have 58 data rows. Lets delete a data record having studentid 6; The SQL statement will be, "DELETE FROM students2 WHERE studentid = 6;" Now if we run the SQL statement again to display all the data rows in 'students2' table, "ELECT * FROM students2;" You can see the studentid 6 is gone. and total data rows are 57.
