What are the best practices for SQL error handling?

The best practices for SQL error handling include using try-catch blocks, logging errors, and providing user-friendly messages.

Can you explain how to implement try-catch in SQL?

Sure! In SQL Server, you can use the TRY...CATCH construct to handle errors. Here's a basic example:

BEGIN TRY
    -- Your SQL code here
END TRY
BEGIN CATCH
    -- Error handling code here
END CATCH

What should I log when an error occurs?

You should log the error message, error number, severity, state, and the time of the error. This helps in diagnosing issues.

How can I provide user-friendly error messages?

You can create custom error messages that are clear and informative, avoiding technical jargon. For example, instead of saying 'SQL error 123', say 'There was a problem processing your request. Please try again later.'
