Help. This has been bugging me for a couple of days now: I am writing a script to regularly transfer data from a MYSQL db to a MSSQL. Being new to MSSQL I'm a bit freaked out about the UNIQUEIDENTIFER (UI) system. I have to INSERT data to a table where I need the UI for items from 2 other tables. This negates my ability to use a JOIN. So I need to grab the UI from within PHP and the reference the variable in the query. To test this I am using a simple SELECT: First I need to get the UI: SELECT CAST(CATALOGGUID as VARCHAR(36)) as CGUID FROM CATALOG WHERE CATALOGNAME='TESTCATALOG' I then assign CGUID to $CGUID The problem query is now: SELECT * FROM CATALOG WHERE CATALOGGUID = '".$CGUID."'; I have tried wrapping the string with curly brackets { & }. But it won't work. I copy the query and put it into SQL QUERY ANALYZER then it works perfectly. The problem is just from inside PHP. Has anybody else had this problem? or knows of a solution? The server OS is Windows 2003 Server. PHP is 5+. Thanx in advance...
