SQL Server Stored Procedures Error Handling

Create a Stored Procedure with TRY...CATCH

Write a stored procedure that inserts a record into a table and uses TRY...CATCH to handle any errors, returning the error message if an error occurs.

Expected output: The procedure inserts data successfully or returns the error message if an error occurs.

Hint: Use BEGIN TRY and BEGIN CATCH blocks and the ERROR_MESSAGE() function.

Implement Transaction Rollback on Error

Modify the stored procedure to include a transaction that commits on success and rolls back on error.

Expected output: Data is rolled back if an error occurs, ensuring no partial inserts.

Hint: Use BEGIN TRANSACTION, COMMIT, and ROLLBACK inside TRY and CATCH blocks.

Errors in SQL Server stored procedures are handled using TRY...CATCH blocks, which allow catching runtime errors and executing error handling code within the CATCH block.

You can use ERROR_NUMBER(), ERROR_MESSAGE(), ERROR_SEVERITY(), ERROR_STATE(), and ERROR_LINE() to retrieve detailed information about the error.

Transactions ensure that a group of operations either all succeed or all fail together, maintaining data integrity. When combined with error handling, you can rollback changes if an error occurs.
