I need to update over 9000 rows. See the query below: A table called contact has got *addr_id *field as null which is incorrect. So now I need to update contact table for each account (cus_acno is in cus table) where contact_addr_id is null. For example using the first of the results below: I need take set addr_id (in contact table) to 187479 where cus_acno = 243492 and con_id = 119360 Example: select distinct(cus_acno), contact.con_id, address.addr_id from address join person using (addr_id) join cus using (per_id) join link_contact using (cus_acno) join contact using (con_id) where contact.addr_id is null; cus_acno | con_id | addr_id ----------+--------+--------- 243492 | 119360 | 187479 393701 | 119824 | 458532 388538 | 118413 | 453178 Thanks CONFIDENTIALITY NOTICE The contents of and attachments to this e-mail are intended for the addressee only, and may contain the confidential information of Argility (Proprietary) Limited and/or its subsidiaries.
