I think this is fine (except for the verbosity) for a small table.I suspect that the optimizer will not see that the subqueries are highly parallel and will chomp through them separately.

Hi Tom, Due to migration to new system we have to change all our account numbers. yes, the predicate in the join for the fictional question without a sample table and data was wrong (everytime I wing it, try to answer WITHOUT TESTING, it comes out wrong. test cases are relevant :) Hi Tom, Thanks for answering my question.

( Client number is consist of branch, Number, Sub Number Currency Code ) We have one big transaction table around 1 million records, having many columns, and at many places client numbers are stored from account master under various columns 1. You told me to use update ( select old.old_account_number, new.new_account_number from old_table old, mapping_table new where old.old_account_number = new.old_account_number ) set old_account_number = new_account_number; But I think my questions still reamin unanswered 1. In your answer only one number say client number will get updated.

I want to write SQL ( not PL/SQL ) to update transaction table from mapping table at one stroke. regards & thanks pjp update ( select old.old_account_number, new.new_account_number from old_table old, mapping_table new where old.old_account_number = new.new_account_number ) set old_account_number = new_account_number; disabling foreign keys during the operation and enabling them afterward. update ( select old.old_account_number, new.new_account_number from old_table old, mapping_table new where old.old_account_number = new.old_account_number ) set old_account_number = new_account_number; (ie in the subquery, match the old account numbers not try matching the old in the old table to the new in the mapping table) Of course if the original posting had the CREATEs/INSERTS etc, it would have a quick and east test.
