What is Autonomous transaction in Oracle
 
05:05
What is Autonomous transaction in Oracle. This is very frequently asking question in Interview. Hello Friend, in this Video You can learn how we can give the answer of Autonomous Transactions. An autonomous transaction is available from Oracle 8i. It is a very cool, useful, unique and powerful feature in oracle. An autonomous transaction is an independent transaction that is initiated by another transaction. It must contain at least one Structured Query Language (SQL) statement. When an autonomous transaction is called, the original transaction (calling transaction) is temporarily suspended. The autonomous transaction must commit or roll back before it returns control to the calling transaction. Once changes have been made by an autonomous transaction, those changes are visible to other transactions in the database. Autonomous transactions can be nested. For use Autonomous Transactions feature in program we have to use PRAGMA AUTONOMOUS_TRANSACTION Key word in Program When to use Autonomous Transactions? • Logging mechanism you need to log an error to your database log table. On the other hand, you need to roll back your core transaction because of the error. And you don't want to roll back over other log entries. • Commits and rollbacks in your database triggers If you define a trigger as an autonomous transaction, then you can commit and/or roll back in that code. • Software usage meter You want to keep track of how often a program is called during an application session. This information is not dependent on, and cannot affect, the transaction being processed in the application. Mutation Error Using autonomous transaction we can avoid mutation error.

Transactions in SQL
 
02:06
Follow this tutorial to learn how to use Transactions in SQL and see how we can roll back to previous changes done in database. Don't forget to check out our site http://howtech.tv/ for more free how-to videos! http://youtube.com/ithowtovids - our feed http://www.facebook.com/howtechtv - join us on facebook https://plus.google.com/103440382717658277879 - our group in Google+ A transaction in SQL is basically the process of one or more changes being made in the database. In this tutorial we will learn the three basic controls of transactions in SQL which are COMMIT, ROLLBACK, and SAVEPOINT Step 1- Commit Command The Commit command is used to save the changes made in the database. To see its implementation, start by first beginning the transaction. Before starting any Transaction in SQL, we have to write the Begin Transaction statement. After that, write the actual action which is required, for example delete from the employee table, where the salary is greater than $2500. After that, write the Commit keyword which confirms that the query is logically correct and can be executed. The Query in this case would be: begin trandelete from EMP where SAL 2500 commit Now when we run the query, a message appears below the Query Editor which shows the number of rows that have been affected by our query. Step 2- Effect of Commit Command After that, fetch all the records from the employee table and it can be seen that all the records which have a salary above $2500 have been deleted. Step 3- Save Points Now let's examine the SAVE POINT command. To understand the concept, we will take an example of a departmental table. Start writing the query by beginning a transaction and then entering in the "Save Transaction" command followed by the transaction name. After that, let's delete a record with the Department number as 10 and then again save the transaction. This time, define the save point as point2. With that done, delete another department, and save the transaction, defining it as point3. Actual Query would be like this: begin tran save tran point1 delete from DEPT where DEPTNO=10 save tran point2 delete from DEPT where DEPTNO=20 save tran point3 After executing it, 2 rows would get affected. Step 4- Departments Deleted Now, see the department table to view the changes. For that, let's fetch all the records from the table. It can be seen that department "10" and "20" has been deleted from the table. Step 5- Roll Back If we want to track back to the previous changes, we can use the save points created earlier along with the Rollback transaction command. The rollback transaction allows us to remove all the modifications made to the data, either from the start of the transaction or to a defined save point. For that, we will use the rollback transaction statement and define the save point after that. Over here, let's roll back to point number 2. The Query would be: rollback tran point2 select * from DEPT Once we execute the query, and fetch all the records from the table, it can be seen that the table now contains the data up till point number 2 in the query. And this is how we can use Transactions in SQL.

Structured Query Language(SQL) as we all know is the database language by the use of which we can perform certain operations on the existing database and also we can use this language to create a database. SQL uses certain commands like Create, Drop, Insert etc. to carry out the required tasks. These SQL commands are mainly categorized into four categories as discussed below: 1. DDL(Data Definition Language) : DDL or Data Definition Language actually consists of the SQL commands that can be used to define the database schema. It simply deals with descriptions of the database schema and is used to create and modify the structure of database objects in database. Examples of DDL commands:  CREATE – is used to create the database or its objects (like table, index, function, views, store procedure and triggers).  DROP – is used to delete objects from the database.  ALTER-is used to alter the structure of the database.  TRUNCATE–is used to remove all records from a table, including all spaces allocated for the records are removed.  COMMENT –is used to add comments to the data dictionary.  RENAME –is used to rename an object existing in the database. 2. DML(Data Manipulation Language) : The SQL commands that deals with the manipulation of data present in database belong to DML or Data Manipulation Language and this includes most of the SQL statements. Examples of DML:  SELECT – is used to retrieve data from the a database.  INSERT – is used to insert data into a table.  UPDATE – is used to update existing data within a table.  DELETE – is used to delete records from a database table. 3. DCL(Data Control Language) : DCL includes commands such as GRANT and REVOKE which mainly deals with the rights, permissions and other controls of the database system. Examples of DCL commands:  GRANT-gives user’s access privileges to database.  REVOKE-withdraw user’s access privileges given by using the GRANT command. 4. TCL(transaction Control Language) : TCL commands deals with the transaction within the database. Examples of TCL commands:  COMMIT– commits a Transaction.  ROLLBACK– rollbacks a transaction in case of any error occurs.  SAVEPOINT–sets a savepoint within a transaction.  SET TRANSACTION–specify characteristics for the transaction.

Difference Between Delete and Truncate
 
03:41
Below is link for Useful Pl/SQL Books http://goo.gl/XMy0tt ---------------------------------------------------------- Difference Between Delete and Truncate in Detail On bigger picture they serve the same purpose but there are many Differences listed with examples Point Delete Truncate 1. Data Recovery Delete: Come under the DML Category, we need to commit or Rollback explicitly to make the changes permanent, so we can recover the data by Rollback command fully with in a session or up to a point if Save Points are used Fall In DDL Category (DDL Command issue the Auto commit implicitly) so no chances of Recovery even not using the Flashback table method. But Truncate operations are also logged , they didn’t generate redo SQL but they are logged , view for truncated data info V$LOGMNR_CONTENTS 2. Data Removal Delete Can remove all or selected data using the Where Clause predicates. Or we can say delete any subset of rows We can Truncate complete table or a partition or sub partition of a table. 3. Speed Delete is Slower because oracle maintain the redo logs for Read Consistency (so that every session connected can see a consistent data at a given point of time ) Delete is very time consuming activity especially when table have numerous indexes and Triggers associated with table Faster as no data logs are maintained no associated trigger firing. 4. DML Triggers Firing DML (Delete) triggers associated with table will fire. DML Trigger will not fire in case of truncate method. 5. Flashback Technology Data can be recovered even after commit operation using Flashback Table options Flashback_transaction_query table will give what to recover and up to which point. Data cannot be recovered in truncate method by Flashback table option. 6. Referential Integrity Constraint Behavior if we don’t have related data in child table then we can delete the data from the parent table or we have variants like On Delete Cascade & on Delete set Null. We can’t truncate a table with enable Referential Integrity Constraint, even there is no data in the child table, we have to disable or drop the constraint if we want to truncate the table. Exception: Truncate is possible if the FK is self-referential means primary key and foreign key are on the same table. 7. Space De allocation or Space Utilization No extent reset with delete when deleting rows from a table, extents are not de allocated, So if there were 50 extents in the table before the deletion, there will still be 50 after the deletion. Truncate: When a table is truncated it will free the space allocated except in case of reuse storage clause. This space can subsequently be used only by new data in the table or cluster resulting from insert or update operations .All extents are de allocated leaving only the extents specified when the table was originally created .Example So if the table was originally created with min extents 3, there will be 3 extents remaining when the tables is truncated. When you truncate a table, NEXT is automatically reset to the last extent deleted. 8. High Water Mark Delete will not reset the high water mark Truncate will reset the High Water mark which is very important for performance point of view as in case of full table scan and full index scan oracle will read all the block under high water mark this makes a lot of difference in terms of performance. 9. Cluster No as such restriction with delete. You cannot individually truncate a table that is part of a cluster. You must truncate the cluster, Delete all rows from the table, or drop and re-create the table. 10. Information Capturing Delete : we can capture the row information what we have deleted using Delete Method, f you are deleting multiple records then use composite data types (collections & records) Truncate Don’t have this feature of capturing the deleted records. 11. Function Based Index Impact DELETE You cannot delete rows from a table if a function-based index on the table has become invalid. You must first validate the function-based index. Truncate: No as such restriction 12. UNUSABLE Indexes Delete no as such feature. Truncate if table is not empty then truncate make all unusable indexes to useable. 13. Complex views You cannot delete data from a Complex view except through INSTEAD OF triggers. But we can delete data from simple Views and MV. We cannot truncate a view simple or complex but you can truncate MV with special Features like Preserve MV Logs and Purge MV Logs. 14. Privileges Delete You need to provide delete table privilege on object. Truncate you must have drop table privilege there is no truncate table privilege exists. 15. Domain Index No as such restriction You cannot truncate the object having domain index in invalid or In progress state

Oracle tutorial : Autonomous Transactions in Oracle 11g PL SQL-PRAGMA What is pragma autonomous_transaction An autonomous transaction is an independent transaction to the main or parent transaction. If an Autonomous transaction is started by another transaction it is not nested, but independent of parent transaction. PRAGMA autonomous_transaction 1)In Oracle session, all of the changes made to data are part of a single transaction. 2)An autonomous transaction is an independent transaction started within another transaction (the main transaction). 3)Autonomous transactions allow you to temporarily suspend the main transaction, perform additional SQL operations, commit or rollback those operations separately, then resume the main transaction. 4)To define an autonomous transaction, we can use a PRAGMA statement PRAGMA AUTONOMOUS_TRANSACTION; CREATE TABLE log_data ( empno NUMBER(6), userid VARCHAR2(30), create_date DATE ); CREATE OR REPLACE TRIGGER add_log BEFORE INSERT OR UPDATE ON employee FOR EACH ROW DECLARE PRAGMA AUTONOMOUS_TRANSACTION; — This statement made this autonomous this trigger BEGIN INSERT INTO log_data VALUES (:new.id, USER, SYSDATE); COMMIT; END; / Insert into EMPLOYEE (ID, NAME, CITY, SALARY, DEPT_NO) Values (20, ‘MY Tech Query’, ‘Mumbai’, 20000, 1) ROLLBACK; SELECT * FROM EMPLOYEE SELECT * FROM LOG_DATA https://www.youtube.com/channel/UCpiyAesWNYOXSz5GPq8lbkA For more tutorial please visit #techquerypond https://techquerypond.com https://techquerypond.wordpress.com https://twitter.com/techquerypond oracle transaction pragma autonomous_transaction
