Question

I am currently trying to issue an update to specific rows of a mysql query. Although some of the rows are not updating correctly. I am assuming this is because the query that I am trying to update is being derived from a bunch of join.

SELECT
        vtiger_users.user_name,
        vtiger_troubletickets.*,
        vtiger_crmentity.*  
    FROM
        vtiger_troubletickets
    LEFT JOIN(
        vtiger_crmentity,
        vtiger_users
    )ON(
        vtiger_crmentity.crmid = vtiger_troubletickets.ticketid AND
        vtiger_crmentity.smownerid = vtiger_users.id
    )WHERE
        vtiger_troubletickets.status != "Closed"
    UPDATE vtiger_troubletickets 
LEFT JOIN(vtiger_crmentity, vtiger_users
)ON
(vtiger_crmentity.crmid = vtiger_troubletickets.ticketid AND vtiger_crmentity.smownerid = vtiger_users.id) SET smownerid = '6'
WHERE ticket_no='TT63'

Now….that query works fine in regards to returning the data I want. When I try to update the data this query returns with this statement:

UPDATE vtiger_troubletickets t 
LEFT JOIN (vtiger_crmentity, vtiger_users) 
       ON (vtiger_crmentity.crmid = t.ticketid 
       AND vtiger_crmentity.smownerid = vtiger_users.id) 
SET smownerid='1' AND t.status='Abandon' 
WHERE t.ticket_no='TT63'

It says it has worked, but does not update the smownerid or the status of the ticket aside from assigning the values as null. Help is much appreciated.

The AND here:

SET smownerid='1' AND t.status='Abandon'

should be a comma:

SET smownerid='1', t.status='Abandon'

See the UPDATE syntax in the MySQL manual.

UPDATE [LOW_PRIORITY] [IGNORE] table_references
SET col_name1={expr1|DEFAULT} [, col_name2={expr2|DEFAULT}] ...
[WHERE where_condition]        ^
                               ^ comma
