Harvinder, Spool this to a file, then run it after re-enabling your PK. BTW, you could do the reverse of this to disable the FKs, too. Select 'Alter Table ' || Table_Name || ' Enable Constraint ' || Constraint_Name || ' ;' From User_Constraints Where R_Constraint_Name = Re-Enabled_PK_Name ; Jack Jack C.

Title: RE: ENABLING FOREIGN KEY CONSTRAINTS -Original Message- From: Harvinder Singh [mailto:[EMAIL PROTECTED]] When we do alter table table_name disable primary key cascade;..it also disable all the foreign key constraints but when we after do alter table table_name enable primary key..it does not enable foreign keys is there any syntax that we can enable all th foreign keys referencing particular table.. Use the SQL from SQL approach: select 'alter table ' || b.owner || '.' || b.table_name || ' enable constraint ' || b.constraint_name || ' ;' as sql_text from dba_constraints a, dba_constraints b where a.owner = 'TABLE_WITH_PK_OWNER' and a.table_name = 'TABLE_WITH_PK_NAME' and a.constraint_type = 'P' and b.constraint_type = 'R' and b.r_owner = a.owner and b.r_constraint_name = a.constraint_name and b.status = 'DISABLED' ; The query will generate all the SQL statements you need to re-enable the foreign key constraints.
