Invalid column error in SQL Server 2008 - sql

Question

I am trying to run the following query,
DECLARE #p_UserName as nvarchar(100)
DECLARE #p_Department as int
DECLARE #p_Section as int
DECLARE #p_SubSection as int
DECLARE #p_PermissionGroup as int
DECLARE #p_DistributionGroup as int
DECLARE #p_Permission as nvarchar(100)
DECLARE #p_IfPerChecked as bit
DECLARE #p_Role as int
SET #p_UserName = ''
SET #p_Department = NULL
SET #p_Section = NULL
SET #p_SubSection = NULL
SET #p_PermissionGroup = NULL
SET #p_DistributionGroup = NULL
SET #p_Permission = ''
SET #p_Role = NULL
SELECT Users.EnglishName,
(SELECT Designation.TitleEnglish FROM Designation WHERE Users.Designation = Designation.ID) AS [Role],
(SELECT Department.TitleEnglish FROM Department WHERE Users.DepartmentID = Department.ID) AS [Department],
(SELECT Section.TitleEnglish FROM Section WHERE Users.SectionID = Section.SectionID) AS [Section],
(SELECT SubSection.TitleEnglish FROM SubSection WHERE Users.SubSectionID = SubSection.SubSectionID) AS [Sub-Section],
(SELECT Groups.TitleEnglish FROM Groups WHERE
(SELECT UserRights.GroupID FROM UserRights WHERE Users.UserID = UserRights.UserID) = Groups.GroupID
AND Groups.IsDistribution = 0
) AS [Permissions Group],
(SELECT Groups.TitleEnglish FROM Groups WHERE
(SELECT UserRights.GroupID FROM UserRights WHERE Users.UserID = UserRights.UserID) = Groups.GroupID
AND Groups.IsDistribution = 1
) AS [Distribution Group],
(CASE
WHEN Users.ApplyUserRights = 1 THEN dbo.fn_GetUserPermissions('Users', Users.UserID)
WHEN Users.ApplyUserRights = 0 THEN dbo.fn_GetUserPermissions('Groups', (SELECT GroupID FROM UserRights WHERE Users.UserID = UserRights.UserID))
END) AS [Permissions]
FROM Users WHERE
((#p_UserName <> NULL OR #p_UserName <> '') AND #p_UserName = Users.UserName) OR
((#p_Department <> NULL OR #p_Department <> 0) AND #p_Department = Users.DepartmentID) OR
((#p_Section <> NULL OR #p_Section <> 0) AND #p_Section = Users.SectionID) OR
((#p_SubSection <> NULL OR #p_SubSection <> 0) AND #p_SubSection = Users.SubSectionID) OR
((#p_PermissionGroup <> NULL OR #p_PermissionGroup <> 0) AND #p_PermissionGroup = (
SELECT Groups.GroupID FROM Groups WHERE
(SELECT UserRights.GroupID FROM UserRights WHERE Users.UserID = UserRights.UserID) = Groups.GroupID
AND Groups.IsDistribution = 0
)) OR
((#p_DistributionGroup <> NULL OR #p_DistributionGroup <> 0) AND #p_DistributionGroup = (
SELECT Groups.GroupID FROM Groups WHERE
(SELECT UserRights.GroupID FROM UserRights WHERE Users.UserID = UserRights.UserID) = Groups.GroupID
AND Groups.IsDistribution = 1
)) OR
(1 = CASE
WHEN Users.ApplyUserRights = 1 AND #p_Permission = 'AllowChangePassword' THEN 0
ELSE dbo.fn_CheckPemission(#p_Permission, UserID)
END) OR
((#p_Role <> NULL OR #p_Role <> 0) AND #p_Role = Users.Designation) OR
(1 = 1)
GROUP BY CASE #GroupBy
WHEN 'DepartmentID' THEN Users.DepartmentID
WHEN 'SectionID' THEN Users.SectionID
WHEN 'SubSectionID' THEN Users.SubSectionID
ELSE Users.EnglishName
END
And I keep getting the error
Column 'Users.EnglishName' is invalid in the select list because it is not contained in either an aggregate function or the GROUP BY clause.
Please help!

Answer 1

Like the message states, you need to group by the EnglishName column unless it is used in an aggregate function(Max or sum or likewise).

Answer 2

The issue is evident from your error message. Use GROUP BY in case of aggregate functions.
