The Delete Query in Microsoft Access
 
04:09
It is really important that if you are using a delete query you have made a copy or backed up your data. An Access delete query will delete data based on criteria you set. You cannot undo it.

php tutorial in hindi - Difference between DROP, DELETE and TRUNCAT table in mysql
 
21:38
Difference between DROP, DELETE AND TRUNCAT in mysql DELETE ------ DML (Data manipulation language) 1)The DELETE command is used to remove rows from a table. 2)After performing a DELETE operation you need to COMMIT or ROLLBACK the transaction to make the change permanent or to undo it. 3) Delete operation perform for all rows or single row, But it does not free the space containing the table. TRUNCAT --DDL (Data definition language) 1)TRUNCATE removes all rows from a table. 2) can't ROLLBACK operation 3) Free the space containing the table DROP --- DDL (Data definition language) 1)The DROP command removes a table from the database.

Can you flashback table into SYSTEM tablespace?
 
10:02
Flashback feature in Oracle database is well known to roll back the table to a specific timestamp (depends on undo retention) or to restore dropped table and many more. We must have used this flashback feature so far on application schema objects and found working without any issues. As an Oracle DBA did you configure any tools (might be monitoring, RMAN catalog or any) with objects created in SYSTEM tablespace? If so, you probably would see some problems later when you need to use Flashback on these objects though they are not Oracle supplied objects. Let us go through a case study which will clearly explain you the functionality of Flashback table. Did you like the video? Subscribe now, Like it and share it.
