Hi,
I have the following query, I would like to add a column which concatenates the other 4 created columns, but doesn't recognize the concat function:

SELECT geo_orig O
,'001' D
,mode_dom M
,'$0000' C
,val V0
,val_f Vf
,val_cv Vcv
,square(val*val_cv) Vv
,ton T0
,ton_f Tf
,ton_cv Tcv
,square(ton*ton_cv) Tv
,tmile TM0
,tmile_f TMf
,tmile_cv TMcv
,square(tmile*tmile_cv) TMv

,OGIDX = CASE
WHEN LEFT(GEO_ORIG,2)='01' THEN '10000000'
WHEN LEFT(GEO_ORIG,2)='02' THEN '2000000'+RIGHT(GEO_ORIG,1)
WHEN LEFT(GEO_ORIG,2)='03' THEN '3000000'+RIGHT(GEO_ORIG,1)
WHEN LEFT(GEO_ORIG,2)='04' THEN '4'+RIGHT(GEO_ORIG,2)+'00000'
ELSE '5'+SUBSTRING(GEO_ORIG,8,7)
END

,'10000000' DGIDX

,MIDX = CASE
WHEN mode_dom = '1' THEN '10000000'
WHEN mode_dom IN ('13','18','19') THEN '200000' + CAST(mode_dom as char)
WHEN mode_dom = '2' THEN '2000000' + CAST(mode_dom as char)
WHEN mode_dom IN ('3','6','7') THEN '3000000' + CAST(mode_dom as char)
WHEN mode_dom IN ('11','12') THEN '300000' + CAST(mode_dom as char)
WHEN mode_dom IN ('14','15','16','17','18') THEN '400000' + CAST(mode_dom as char)
END

,'10000000' CIDX
, concat (OGIDX , DGIDX , MIDX , CIDX) IDX

FROM [bts].[cf07ur00].[a01]

Change:

, concat (OGIDX , DGIDX , MIDX , CIDX) IDX

To:

, OGIDX+DGIDX+MIDX+CIDX IDX

thank you, but if I do this change the following error appears because the other 4 columns I am adding are also created on the fly:

Msg 207, Level 16, State 1, Line 42
Invalid column name 'OGIDX'.
Msg 207, Level 16, State 1, Line 42
Invalid column name 'DGIDX'.
Msg 207, Level 16, State 1, Line 42
Invalid column name 'MIDX'.
Msg 207, Level 16, State 1, Line 42
Invalid column name 'CIDX'.
