Question

I have this SQL Statement:

de.SqlStatement = "SELECT A.Name, A.Catagory , COUNT(Patient_ID) AS PNO FROM PatientApplyToAssociation P INNER JOIN Association A on A.Association_ID = P.Association_ID WHERE A.Catagory='" & "health" & " '" & "' GROUP BY A.Name '"

with this Exception:

System.Data.SqlClient.SqlException was unhandled by user code
Class=16
ErrorCode=-2146232060
LineNumber=1
Message=Column
‘Association.Name’ is invalid in the select list because it is not
contained in either an aggregate function or the GROUP BY clause.

I had this exception when I added the where clause, It seems that the compiler cant see the Group By Section , because of the quotation ending before it, I tried to write it like this:

de.SqlStatement = "SELECT A.Name, A.Catagory , COUNT(Patient_ID) AS PNO FROM PatientApplyToAssociation P INNER JOIN Association A on A.Association_ID = P.Association_ID WHERE A.Catagory='" & "health" & "' GROUP BY A.Name '" & " '"

But it was an Incorrect syntax near ' '.

Any ideas?

I’m pretty sure you don’t want the ' around the GROUP BY clause:

SELECT A.Name, A.Catagory
     , COUNT(Patient_ID) AS PNO 
  FROM PatientApplyToAssociation P 
 INNER JOIN Association A 
    ON A.Association_ID = P.Association_ID 
 WHERE A.Catagory='" & "health" & " '" & " GROUP BY A.Name
