I am trying to do a search for records in SQL that have a userID of the current logged in user. I have set the SessionUID to the GUID of the user logged in. When I use this select statment I get

Operator '&' is not defined for string " SELECT count(PhotoId) AS imagec" and type 'Guid'.


 SELECT count(PhotoId) AS imagecount FROM Photos WHERE UserID = '" & Session("SessionUID") & "'"

Please help
Thanks

SELECT count(PhotoId) AS imagecount FROM Photos WHERE UserID = '" & CType(Session("SessionUID"), String) & "'"

Also try using "Option Strict" to catch this in the future

Sorry the error I get now is

Conversion from type 'Guid' to type 'String' is not valid.

The problem before was session expired
