Join Martin Guidry for an in-depth discussion in this video Using transactions, part of SQL Server: Triggers Stored Procedures and Functions.
Database developers can and should use transactions, to provide a logical…grouping of actions.…Transactions can happen inside of a stored procedure or outside of the stored procedure.…I typically do most of my transactions inside of stored procedures.…And we'll talk a few reasons about why.…I have on the screen some code you can get from the exercise files.…It's a basic stored procedure, that's going to either delete or deactivate an author.…There's one UPDATE statement that runs on line 6, 7 and 8.…That's going to set the particular author's active status to 0, meaning he is inactive.…
And then lines 10, 11 and 12, set his phone number equal to Null.…So this is a hypothetical where we want to stop tracking personal information…about people that are no longer active.…Lines 14 to 17, allow us to potentially roll- back the transaction if there's a problem.…So this will help us avoid the situation, where we might end up with an author…who we couldn't mark as inactive.…We don't want to still remove his phone number.…
