Can get the Union to work correctly - sql

Question

Select CorpID,
Convert(VarChar(2),Month(E.BeginDate)) + '/' + Convert(VarChar(4),Year(E.BeginDate)),
Count(Year(e.BeginDate)) As 'total Screen'
--Count(Month(E.CurrentBeginDate))
From dbo.NonCalls E
Where E.BeginDate between {d'2013-01-01'} and {d'2013-12-31'}
Group By CorpID, Year(E.BeginDate),Month(E.BeginDate)
Union ALL
Select CorpID,
Convert(VarChar(2),Month(E.CurrentBeginDate)) + '/' + Convert(VarChar(4),Year(E.CurrentBeginDate)),
Count(Year(e.CurrentBeginDate)) As 'total Screen'
--Count(Month(E.CurrentBeginDate))
From dbo.Employee E
Where E.CurrentBeginDate between {d'2013-01-01'} and {d'2013-12-31'}
Group By CorpID, Year(E.CurrentBeginDate),Month(E.CurrentBeginDate)
--Order By CorpID, Year(E.CurrentBeginDate), Month(E.CurrentBeginDate)
I change my code to this and now I get the numbers that i was looking for the only problem is that it's not sorted i need it to sorted by Corpid and then by date 01-02-03 etc I'm not quite sure
how to get that accomplish any help would be greatly apreciated.

Answer 1

You have 2 CurrentBeginDate in your second part of the UNION causing that one to return 5 columns, but the first part only 4 columns
SELECT
CorpID ,
CurrentBeginDate <--HERE,
CONVERT(VARCHAR(2), MONTH(E.CurrentBeginDate)) + '/'
+ CONVERT(VARCHAR(4), YEAR(E.CurrentBeginDate)) AS CurrentBeginDate <--HERE,
COUNT(YEAR(e.CurrentBeginDate)) AS 'total Screen' ,
'' AS d1
As the error message says, for the union to work, it need the same amount of columns returned from all parts of the query.

Answer 2

As an answer to your "new question about sorting the now correctly unioned data:
You need to treat the unioned resultset as a derived table and select from it with your order. by.
SELECT *
FROM (<your unioned query)
ORDER BY CorpID
,Year(CurrentBeginDate)
,Month(CurrentBeginDate)
