Updating tables through object views in oracle waydating

Hence I am trying to use a WITH clause during update but I'm hitting error in it.Can you advise the solution or any alternative way to do this: WITH x AS (SELECT rowid,case when count(distinct leg_division)over(partition by leg_distributor_vendor) = 1 THEN NULL ELSE sap_division end FROM sap_x_tt_agreement_ss1 WHERE dep_error_code IS NULL AND val_error_code IS NULL) UPDATE sap_x_tt_agreement_ss1 y,x SET sap_division = NULL WHERE x.rowid = y.rowid; select * from v$version; Error: ORA-00928: missing SELECT keyword Do let me know if test script is required.If you want more help with this, please provide the DDL for your tables (create table, constraints indexes) and an execution plan for the update.
