How can I handle errors in SQL DML operations?

How can I handle errors in SQL DML operations?

You can handle errors in SQL DML operations using TRY...CATCH blocks or by checking the @@ERROR variable after each statement.

Can you give me an example of using TRY...CATCH?

Sure! Here's a simple example:

BEGIN TRY
    INSERT INTO Employees (Name, Age) VALUES ('John Doe', 30);
END TRY
BEGIN CATCH
    PRINT 'Error occurred: ' + ERROR_MESSAGE();
END CATCH

What happens if an error occurs during a transaction?

If an error occurs during a transaction, you can roll back the transaction to maintain data integrity. Use the ROLLBACK command in the CATCH block.

Are there any specific error codes I should be aware of?

Yes, SQL Server has specific error codes for different issues. You can use the ERROR_NUMBER() function in the CATCH block to get the error code.
