One catch that I’ve been trying to work around this week – if this is for a IIS/.Net web page using a SqlDataSource (or maybe it’s called a sqlDataControl), the object will NOT use views properly.

It was a fun post to write.Ĭomment by Michael J. One suggestion is to use the user-settable performance counter via sp_increment_counter1 then Poof! You’ve got your own deprecated-features performance counter just like Microsoft.Īwesome post. You can log or track trigger use using any way you’re comfortable with. Just add some logging statement to the definition of the triggers. You can still make sure gradually by logging whenever someone uses the old schema. The applications can transition gradually to the new way of doing things.Įven if you believe every application uses only the new schema.

This helps with migrations because applications are now free to expect the new or old schema.

You might want to use this strategy when you don’t have control over every application using your database.

INSERT VERTEBRATES (Name, VertebraeCount) INSERT ANIMALS_BASE (Name) SELECT Name FROM inserted INSERT VERTEBRATES (Name, VertebraeCount ) SELECT Name, VertebraeCount Instead of insert as INSERT ANIMALS_BASE (Name ) SELECT Name FROM inserted

I learned that not only are triggers allowed on views but INSTEAD-OF triggers will work on any kind of view, updatable or not.

I thought that triggers couldn’t be defined on views but.

If it was simple enough we call the view “updatable”.

I knew that insert/update/delete statements could be executed on views if the view was simple enough.

I don’t mind at all.Īside: Have I ever mentioned how amazing the people I work with are? I work for a great company and we’re hiring like crazy. You know, I continue to learn tons while talking to friends at work even though I’m the in-house SQL Server specialist. (I thought no at first, but keep reading). It’s something I learned while talking to a friend at work. He wondered whether SQL Server had any feature similar to the rule system over at Postgres. I’m sharing something that I learned this week. Thanks for your help.What’s up with triggers on views? What kind of patchwork monster is this? You were right, a job running is blocking it.

Probably an insert that is in progress.Charlie = Msg 3903, Level 16, State 1, Line 1736The ROLLBACK TRANSACTION request has no corresponding BEGIN TRANSACTION If you try to create the trigger then go another window in ssms and typeEXEC sp_who2You will probably see that it is blocked by another process.

Any theories? I have a DDL_DATABASE_LEVEL_EVENTS trigger on the live database, would this block normal triggers?
