Sorry mate, been away, how have you gone?
The connection string and SQL looks ok to me.
is the schema you are passing the same for both web service calls.
Compare the wsdl's generated by referencing the web service in your apps.
See if there is a difference that might indicate a different schema.
Try Update web reference in your client app that is failing.
Try and provide a little more info if possible.
Failing that:
I recommend Soap Scope by Mindreef for diagnosing web service issues.
I beleive there is a trial available for soapscope.
