php mssql connection

I have a connection to MSSQL database which I use mssql_query and mssql_fetch_assoc

I have problem when I use a join in the statement.
when just connecting to a single table in the SQL part

SELECT        id, sName, iStatus
FROM            [SQL01].[dbo].[KPIDay]

If i do not put the [sqldatabase].[dbo].[tablename]
I get an internal error

but I am stuck with is statement  work in sql builder but no in php

SELECT        Lead_T.sName AS Expr1, LeadSource_T.sName, TransferClient_T.sName AS Client, TransferSubscription_T.sName AS Subs, LeadTransfer_T.zXUpdtdWhn AS Date, 
                         LeadTransfer_T.zXUpdtdBy AS [Updated By], TransferClient_T.id
FROM            TransferClient_T INNER JOIN
                         LeadSource_T INNER JOIN
                         LeadTransfer_T ON LeadSource_T.id = LeadTransfer_T.FKiSourceID INNER JOIN
                         Lead_T ON LeadTransfer_T.FKiLeadID = Lead_T.id ON TransferClient_T.id = LeadTransfer_T.FKiClientID INNER JOIN
                         TransferSubscription_T ON LeadTransfer_T.FKiSubscriptionID = TransferSubscription_T.id
WHERE        (LeadTransfer_T.zXUpdtdWhn BETWEEN CONVERT(DATETIME, '2012-10-29 00:00:00', 102) AND CONVERT(DATETIME, '2012-10-29 23:59:59', 102)) AND 
                         (TransferClient_T.id = 27)
ORDER BY TransferClient_T.zXUpdtdWhn, Date, LeadSource_T.sName DESC

not sure where I need the [sqldatabase].[dbo].[tablename]
