Question

I’m using query, where the piece is:

...where code in ('va1','var2'...')

I have about 50k of this codes.

It was working when I has 30k codes, but know I get:

The query processor ran out of internal resources and could not produce a query plan. This is a rare event and only expected for extremely complex queries or queries that reference a very large number of tables or partition

I think that problem is related with IN…

So now I’m planning use foreach(string code in codes)
…where code =code

Is it good Idea ??

Answer 1

I suggest you create a temporary table containing all the codes you want to match, and join against that instead.

However, we haven’t really seen enough of your code to comment for sure.
