Hi SSC,
Is there a deterministic way to tell all the procedures which reference a certain table type? Basically, since you can't alter table types or even drop them while referenced, I have to do some sneaky rename logic, and use sp_refreshsqlmodule on the procs.
I can get close with simple pattern matching, and looking at sys.parameters, but that won't deterministically catch all references INSIDE procs. Clearly under the covers SQL is doing that check, or it wouldn't yell at me, but do you know of a sql statement I can run to do that?

The most reliable way I have found is to use the free tool Redgate SQL Search[/url]

But no way to do it in SQL? I'm trying to avoid having to have a real live human have to look it all up ahead of time.

You could use a wild card search on the definition column of sys.sql_module.

Yeah, I actually mentioned that approach, but it's not always possible to get JUST those with those procs. If you had a TT called MyTableOfDoom and a presentation table called MyTableOfDoomAndTacos, the latter would match as well. I guess it wouldn't be the end of the world to refresh unnecessary procs, but I'd rather know exactly.

I would think sys.sql_expression_dependencies would contain those references, since a table-type is in sys.objects, type = 'tt'.

Only way to know for sure is test it out. I may do that later if I have time.

Having that issue right now, the problem comes not when the type is in the code, but when it's a parameter. An easy way to find problems would be like this:

SELECT pro.name

FROM sys.parameters par

JOIN sys.procedures pro ON par.OBJECT_ID = pro.object_id

JOIN sys.types typ ON par.user_type_id = typ.user_type_id

WHERE typ.name = 'TableTypeName'

Thanks, Luis. sys.parameters is great for solving some weird problem like that.
