    In my asp.net+VB=SQL web i have a query for dropdownlist

     Dim comd2 As New SqlCommand("SELECT distinct EmpNo from Leave ORDER BY CAST(SUBSTRING(EMPNO + '0', PATINDEX('%[0-9]%', EMPNO + '0'), LEN(EMPNO + '0')) AS INT)", con2)

    If I remove DISTINCT from the above query it works for me.

    But want to pick DISTINCT EMPNO from table leave

    Error is as under

    ORDER BY items must appear in the select list if SELECT DISTINCT is specified.
