Hello,
   I have an application that use a Firebird database and I need to 
change a Primary Key on a table by adding a new field.

I can drop a primary key constraint by "ALTER TABLE MyTable DROP 
CONSTRAINT MyINTEG_000" where "MyINTEG_000" is the constraint on my 
development database file.

I cannot use the instruction above because I don't know in all 
production databases of my customers the name of the Primary Key I want 
update.

How I can solve?

Thanks.
