You didn't show us the whole function definition, so this is just
speculation, but I wonder whether any of the function's variable or
parameter names match any of the table column names used in the query.
For instance if you had a function parameter named CATEGORY or
CATEGORY_ID, you'd get surprising results because the value of that
parameter would get substituted for what you're thinking is a column
reference.
