Hi Rade!

I don't know anything about your problem, but you do an unneccessary
double exists. Your above statement can be simplified to

if( exists(Select...)
) then
Exception E....

i.e. drop the "Select 1 From RDB$DATABASE Where exists(" part.

Though I don't know whether this will help anything,
