Why don't you do directly what Query does implicitly? This way it'll be clear what you're doing.
SELECT 0
USE mytable AGAIN ALIAS t2
SET FILTER TO < where conditions >
...
>Fortunately (or not, depending on your pov), the SQL statement is hard coded and not subject to user interference. It is used for a very specific purpose which would become worthless anyway if somebody changed it. It's a real simple statement, but even though there is an index exactly matching the where clause, and an index on DELETED(), when it runs on a table of about 100,000 records, it takes about 10 seconds to run. Doing what I'm doing brings it down to sub 1 second. I'm going to continue trying to find a better option, but I think for now, I may just have to treat this as a temporary fix.
