[firebird-support] Is it possible to suspend a generator?

[grip_2ls]

Hi

I need to insert some data with fixed IDs. The table that I am inserting into 
already has data and a generator for the IDs. The new data is below the value 
of the generator and the IDs do not already exist. Can I suspend the generator 
while I insert these new rows and if so how?

Thanks

Neil
