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.

[@CctnsHelpdesk]

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

[@KSRDatavizon]

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).

DDLs can be rolled back in some recent versions of SQL SERVER

[@KSRDatavizon]

I'd be glad to provide a comprehensive response to the prompt "DDLs can be rolled back in some recent versions of SQL SERVER":
Yes, Data Definition Language (DDL) statements can indeed be rolled back in recent versions of SQL Server. This feature is primarily available in SQL Server 2012 and later versions.
Here's a breakdown of how DDL rollback works:
Transaction Scope: DDL statements must be executed within a transaction scope for rollback to be possible. This is achieved using the BEGIN TRANSACTION and COMMIT TRANSACTION statements.
Rollback Trigger: SQL Server automatically creates a rollback trigger for DDL statements executed within transactions. This trigger captures the necessary information to undo the changes in case of a rollback.
Rollback Mechanism: When a rollback occurs (e.g., due to an error or an explicit ROLLBACK TRANSACTION statement), SQL Server uses the captured information from the rollback trigger to reverse the DDL changes.
Key Points to Remember:
Transaction Scope: DDL statements must be within a transaction for rollback.
Rollback Trigger: SQL Server automatically creates a rollback trigger.
Rollback Mechanism: SQL Server uses the captured information to reverse changes.
Example:
SQL
BEGIN TRANSACTION;
-- Create a new table
CREATE TABLE MyNewTable (
ID INT PRIMARY KEY,
Name VARCHAR(50)
);
-- If an error occurs or you decide to rollback:
ROLLBACK TRANSACTION;
Use code with caution.
Additional Considerations:
DDL Rollback Limitations: While DDL rollback is generally reliable, there might be certain scenarios where it might not be fully effective, such as when the rollback trigger fails or if underlying system changes are involved.
Performance Impact: Using DDL rollback frequently might have a slight performance impact, as it involves additional overhead for the rollback trigger and the rollback process.
Best Practices: Consider using DDL rollback judiciously, especially for critical DDL changes. It's often a good practice to test DDL changes in a non-production environment before applying them to production.
By understanding DDL rollback in SQL Server, you can leverage this feature to enhance data management and recovery capabilities within your database applications.

Also , in the second question , can we use row number () over ( partition by id order by id ) , so that any id that duplicates will have the row no as 2 and the rest will have one , so we can select the records where row number =2 ?

[@maheshtiwari2297]

You can simple do
With cte as (
Select *, row_number() over(partition by Id order by Id) as rnk
From temp)
Delete from cte
Where rnk 1

[@KSRDatavizon]

Yes we can do that as well

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

[@KSRDatavizon]

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

[@awakenedsouls3206]

In the first question of sql coding , the 3rd maximum salary person , can we use large ( salary , 3) , to find the 3rd largest salary and then write an outer query to fetch the employee name from this table with the third largest salary ? Would it also be correct ?

[@ashutoshrai2717]
