Hi,
you can also do this
select 'alter table ',tabschema,'.',tabname, ' DROP Foreign key ', constname, ' ;' from syscat.tabconst where tabschema='URschema' and type='F' > script.dml
this will give you a file called script.dml which will have all the ALTER Table commands for all tables in ur schema with a foreign key. You can check the script before you run it so you can be sure thers nuthing wrong
Bye
