Question

I am trying to retrieve result from a sql queries which returns duplicated userids from Table1 into Table3.

Below is my sql statement:

INSERT INTO Table3(UserID, Name, Issue) 
   SELECT t1.UserID, t1.Name, 'Duplicated userid found in Table1' 
   FROM Table1 t1 
   GROUP BY t1.UserUD  
   HAVING COUNT(*) > 1

However, I received the following error after I tried to run it in my datasource:

Column ‘Table1.Name’ is invalid in the select statement list because it is not contained in either an aggregate functions or the GROUP BY
clause

May I know where is my mistake?

Thank you

Answer 1

INSERT INTO Table3(UserID, Name, Issue) 
SELECT t1.UserID, t1.Name, 'Duplicated userid found in Table1' 
FROM Table1 t1 
GROUP BY t1.UserUD, t1.Name
HAVING COUNT(t1.UserID) > 1

You were missing the field in the group by
