qty I want to update ORDERED_ITEMS table for a few records but exclude any book where BOOKS.bk_flag='X' Would you do this UPDATE ordered_item SET qty = new_qty WHERE order_date = xxxx and cust_id = xxxx and bkno not in (select bkno from books where bk_flag May 06, 2008 - am UTC tell me how you would do an update on a join here? ITEM_NO * ERROR at line 4: ORA-00904: "CLASS_TEST"."ITEM_NO": invalid identifier Any help will be appreciated. If i am updating & using non key preserved tables then exists seems to be quicker one! update account_allocation2 set (sup_hyg_acc_policy,sup_hyg_acc_add)= ( select sup_hyg_acc_policy,sup_hyg_acc_add from acc_hyg_driver where acc_hyg_driver.account_number = account_allocation2.account_number and exists ( select '1' from acc_hyg_driver where acc_hyg_driver.account_number = account_allocation2.account_number )) any ideas?? merge into account_allocation2 using acc_hyg_driver on (acc_hyg_driver.account_number = account_allocation2.account_number) when matched then update set sup_hyg_acc_policy = acc_hyg_driver.sup_hyg_acc_policy, sup_hyg_acc_add = acc_hyg_driver.sup_hyg_acc_addmerge into account_allocation2 using (select * from acc_hyg_driver where account_number in (select account_number from account_allocation2) acc_hyg_driver on (acc_hyg_driver.account_number = account_allocation2.account_number) when matched then update set sup_hyg_acc_policy = acc_hyg_driver.sup_hyg_acc_policy, sup_hyg_acc_add = acc_hyg_driver.sup_hyg_acc_add when not matched then insert (account_number) values ( null )the "using" query only needs to use the IN if acc_hyg_driver might have account numbers that are NOT IN account_allocation2, if acc_hyp_driver only has account numbers in that set, you can just use that table. But the volumes dealt with are account_allocation has 16 million acc_hyg_driver has 6 million and the update does around 6 million records, The current merge takes more than 5 hours with other bottle necks ( includes CPU sharing) which cant be helped!
ID = @parameter Hope I succeded in making it clearer.
You told me to useupdate ( 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 unanswered1. In your answer only one number say client number will get updated.
I want to update the school_code column in the student table with the school_id column in the school code table based on school code and year.
UPDATE SALES_DATA_FAMILY_2007 SET POG_ID= (SELECT POG_HIERARCHY. POG_ID FROM POG_HIERARCHY WHERE SALES_DATA_FAMILY_2007.
POG_ID FROM POG_HIERARCHY WHERE SALES_DATA_FAMILY_2007. If there's more than one row in POD_HIERARCHY, then you need to determine which row from POD_HIERARCHY you wish to use the value from.
FAMILY_ID) ; This will work if and only if there's at most one corresponding row in POD_HIERARCHY for a given FAMILY.

September 26, 2008 - pm UTC you can use mergemerge into t1using t2on (t1.x = t2.a)when matched then update set y = t2.b;if there exist duplicated by t2.a (more than one row with t2.a having the same value), the merge will fail at runtime when it encounters you trying to modify Y in a non-deterministic fashion. Can we use the WHERE clause in the merge statement?
