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. Define the outer query referencing the CTE name.What’s up with triggers on views? What kind of patchwork monster is this?

UPDATE UserPackages SET packagestatus='TRUE' WHERE P_ID=2 INSERT INTO UserPackages VALUES (2,1,1,'TRUE',NULL,NULL) Set BuyDate=GETDATE(), Expirydate = dateadd(dd,C.VALIDITIY,getdate())Īfter I performed one update and insert action, we could have below output. Please try with below statement and check whether it is helpful to you: CREATE TRIGGER BuyDateUpdate ON UserPackages In addition, we also need to join packages table since we need the value of VALIDITIY to update the value of Expirydate. Otherwise we would get the error 'The logical tables INSERTED and DELETED cannot be updated'. from table inner join inserted' to trigger the row of data which is inserted or updated.īesides, we could not use 'update a set.
