Hi, I am whether I can update a field in one table from valuse in another table using a simple SQL Statement ?
the Tables are :
T1 T2 Code Code Value Value otherstaff..
where Code is the PK of both tables (1 to 1)
and I think the Update statement should be:
Update T1 set T1.Value = T2.Value
where T1.Code = T2.Code (Runs perfect in SYBASE !)
but check the Oracel Server Language Refernece book, the Update can not have a FROM clause, but then How you updating a field from another table in SQL ?
Thanks for any help
