Question : union

I added m.description to sp , where do I need to put something that my union wouldn't complain about All queries combined using a UNION, INTERSECT or EXCEPT operator must have an equal number of expressions in their target lists.


alter procedure [dbo].[Getfinding]
(
      @iMedReviewID int,
        @iReview_num int      
)
as

SELECT
SortOrder as rank,
'Y' SELECTED,  
'Y' SELECTED_finding,  

f.finding_ID,  
f.ERR_CODE_ID,  
ERR_CODE.[DESC],  
f.TYPE,  
f.REVIEW_ID,  
f.REVIEW_NUM,  
f.ERR_AMT,  
f.BILLED_CODES_UNITS,
f.OVER_UNDER,  
f.POLICY_REF,
f.CORRECT_CODES_UNITS,
ERR_CODE.CODE,
ERR_CODE.SORTORDER,
m.description

FROM finding f
inner JOIN ERR_CODE ON
(
      f.ERR_CODE_ID = ERR_CODE.ERR_CODE_ID
)
inner Join med_qualifier m on
(
cast(CAST(f.POLICY_REF as VARCHAR(10)) As int) = m.Med_Qualifier_id
)
WHERE f.REVIEW_ID = @iMedReviewID
AND f.TYPE = 'M'
AND f.REVIEW_NUM = @iReview_num

UNION ALL

SELECT
SortOrder as rank,
'N' SELECTED,  
'N' SELECTED_finding,  

NULL,  
ERR_CODE.ERR_CODE_ID,  
ERR_CODE.[DESC],  
ERR_CODE.TYPE,  
@iMedReviewID,  
@iReview_num,  
null,  
null,

null,
ERR_CODE.CODE,
ERR_CODE.SORTORDER,

Answer : union

Just add a null to the end of your query

      @iMedReviewID int,
