Question

I have to update the a table in sql server from one database to another and i was wondering how to do that with

here is my example

UPDATE [Logix].[sysdba].[TICKET] (
    STATUSCODE) 
SELECT TICKETID, GM_NUMBER, STATUSCODE
 FROM [Logix_Dev].[sysdba].[TICKET]
 where GM_NUMBER <> ''

but i feel like this is the wrong syntax…basically what i want to do is select all the records from the TICKET table in the Logix_Dev database and update the statuscode on the Logix database where the TICKETID match….

Use aliases to make your life easier (same instance):

UPDATE l
SET l.STATUSCODE=s.someVal
FROM Logix.sysdba.Ticket l
INNER JOIN Logix_dev.sysdba.ticket s
ON s.ID = l.ID

Of course you will need to replace s.ID and l.ID with the appropriate columns (TicketID ?):

UPDATE l 
SET l.STATUSCODE=s.STATUSCODE 
FROM Logix.sysdba.Ticket l 
INNER JOIN Logix_dev.sysdba.ticket s 
ON s.TicketID = l.TicketID 
WHERE s.GM_NUMBER = ''

If they are on the same instance then do not need two dots (..). If it is a linked server or on another instance you need two dots (..):

Linked server:

UPDATE l
SET l.STATUSCODE=s.someVal
FROM Logix.sysdba.Ticket l
INNER JOIN Logix_dev..sysdba.ticket s
ON s.ID = l.ID
