Steve Jones gives it the ol’ college try:
This is a common error handling technique in other languages. C# uses it, as does Java, while Python has TRY EXCEPT. There are other examples, but these are good habits to get into when you don’t know how code will behave or if there is something in your data or environment that could cause an issue.
In SQL, I think many of us get used to writing one statement in a query and forget to do error handling, or transactions. However, this can be a good habit as your code might grow and people might add more statements that should execute.
Read on for a few examples of how to use SQL Server’s TRY-CATCH functionality. It’s not perfect, but as Steve shows, there are definitely good uses for it.
