For Referential Integrity you can use foreign keys (they are supported by InnoDB table types). There is no ON UPDATE CASCADE in MySQL yet, but you can use ON DELETE CASCADE and ON DELETE SET NULL since version 3.23.50 BN> But i changed to mysql in which i need to BN> write the Query Yes, you need to update table 'tbprocess' manually.

Relation Among Tables Urgent()
Hi all, hi all, I want to create an one to one relationship among tables using SQL. How can i do this. I creates an relation but it dose not expect my needs. For Ex they are two table say tbset nad tb tbprocess. If i set an one to one relation between the two tables in which the master table is tbset. If i change the values in the tbset table the change should be refleted in the slave table that is tbprocess. I think i can do this in msacess. But i changed to mysql in which i need to write the Query(There is no gui for mysql as like msacess).
