I encountered a problem about how to limit a sql query "in" condition to 1000 elements at most, hence i decided to solve this by assign each 1000 element to a variable and then use "or" to put those strings together to form this query.

This was my first codes:

Now the problem is that coldfusion just can't convert the #x# in #evaluate("key_id_#x#")#.
So my idea of getting dynamic variables such like "key_id_1", "key_id_2" vanished into the void.

Here is my final solution of this problem:

I assigned every 1000 elements to the same variables and restored it after outputting.
Reusing one single variable seems the only way out in the case.
