If there is that many values to compare against - wouldn't it be easier/more efficient to create a file to contain these values and perform a join against it?

Subject: [EXTERNAL] SQL IN predicate - length restrictions?

Hi,



Anyone knows about a limit in how many values that can be put into an IN
predicate?

Testing reveals that around 1000 values ( don't ask ) performance drops
significantly.

I'm not able to find any restrictions in the SQL manual.



Thanks!



Stefan
