PMJI, but you may be having problems because DESC is a reserved word. You can either rename the field, or use the AS clause to use a different field name in the resulting cursor.

I imagine that it is intermittant in that the SQL sometimes works and sometimes doesn't: it must be related to queries run before, perhaps, or if you have read the field into memory. I would guess that it doesn't happen the first time that you read it (otherwise you would not have been able to design the thing in the first place).

>It says DESC is not found as the field is evaluated to an EXP_1. Basically, the error is generated from the next line which deals to read the DESC field. The problem is that the SQL is sometimes evaluating it and sometimes not. So, if I reference to DESC after, I may have the error.
