Disable all table constraints in Oracle

Question

How can I disable all table constrains in Oracle with a single command? This can be either for a single table, a list of tables, or for all tables.

Answer 1

You can execute all the commands returned by the following query :

select 'ALTER TABLE '||substr(c.table_name,1,35)|| ' DISABLE CONSTRAINT '||constraint_name||' ;' from user_constraints c --where c.table_name = 'TABLE_NAME' ;
