i have written the following select

select ceb.New_LegacyCDBID
FROM   ContractExtensionBase ceb
inner join ContractBase cb
on ceb.contractid=cb.contractid
where New_LegacyCDBID  is not null
and statecode = 4 and statuscode = 5

what i want to do now is update ceb.New_LegacyCDBID  using the above join but not sure of syntax?

UPDATE ContractExtensionBase ceb INNER JOIN ContractBase cb
ON ceb.contractid = cb.contractid
SET ceb.New_LegacyCDBID = ???
WHERE statecode = 4 AND statuscode = 5;

You need to replace the ??? with your data and add any addition WHERE conditions.

*additional WHERE conditions.
For syntax, I always go to www.w3schools.com and go to their SQL tutorial. They have just about everything.

hi

getting the follow error

Incorrect syntax near 'ceb'.
I'm pretty sure you can't have a join clause in an update statement. I just checked both SQL Server's and Oracle's documentation and neither of them say you can. I think you just need to find a different way to identify the rows you want to update.

Are statecode and statuscode both a part of the ContractBase table?

On second examination, it looks like you are implementing table inheritance. Is that why you want to join in the update?

Sorry, I had Access on the brain. Try this

UPDATE ceb
SET ceb.New_LegacyCDBID = ???
FROM ContractExtensionBase ceb INNER JOIN ContractBase cb
ON ceb.contractid = cb.contractid
WHERE statecode = 4 AND statuscode = 5;
Ok, forget my comment. I see lee's syntax in SQL Server's documentation now.

Commented:
UPDATE ceb
SET ceb.New_LegacyCDBID = ???   -- TODO add your  newvalue here
FROM ContractExtensionBase ceb 
INNER JOIN ContractBase cb ON ceb.contractid = cb.contractid
WHERE statecode = 4 AND statuscode = 5;
