    Always check the stored procedures and triggers. For SQL it must follow SDLC with the user's requirements that were communicated to management. No matter what flavor ov Unix box. Sun, Solaris etc. Guys with main frame and mid range experience were easiest to train instead of PC dudes.

  • @user-rh1hr5cc1r
    @user-rh1hr5cc1r 5 місяців тому

    But we can use aggregated column in where by using nested query/sub query/cte

    • @KSRDatavizon
      @KSRDatavizon  5 місяців тому

      You're absolutely right! While aggregate functions can't be directly used in the WHERE clause of most relational databases, you can achieve the desired filtering effect by using a subquery (also called a nested query) or a Common Table Expression (CTE).

    in the first question you said the main difference between DDL and DML is DDL command can not be rolled back.

    begin tran
    Drop table Brands
    Rollback tran
    as above query works with rollback

    Hi Sir, as i understand once commit after transaction we can't rollback either Truncate or Delete or drop.

    • @KSRDatavizon
      @KSRDatavizon  5 місяців тому

      That's correct! Once a transaction is committed, you can't rollback changes made by Truncate, Delete or Drop operations.
