I have a SQL Table structured with columns something like this
A1, A2, A3, B1, B2, B3, C1, C2, C3
Multiple records might be available under each Column
e.g.
A1, A2, A3, B1, B2, B3, C1, C2, C3
01, 02, 03, 00, 00, 00, 00, 00, 00
04, 05, 06, 00, 00, 00, 00, 00, 00
07, 08, 09, 00, 00, 00, 00, 00, 00
Records for each column will mostly be in Either in columns Ax Bx or Cx
e.g.
A1, A2, A3, B1, B2, B3, C1, C2, C3
00, 00, 00, 01, 02, 03, 00, 00, 00
00, 00, 00, 04, 05, 06, 00, 00, 00
00, 00, 00, 07, 08, 09, 00, 00, 00
or
A1, A2, A3, B1, B2, B3, C1, C2, C3
00, 00, 00, 00, 00, 00, 01, 02, 03
00, 00, 00, 00, 00, 00, 05, 05, 06
00, 00, 00, 00, 00, 00, 07, 08, 09
but might occasionally be shown in both.
e.g.
A1, A2, A3, B1, B2, B3, C1, C2, C3
01, 02, 03, 00, 00, 00, 09, 08, 07
04, 05, 06, 00, 00, 00, 06, 05, 04
07, 08, 09, 00, 00, 00, 03, 02, 01
I need to return a report to shows data underneath one another as follows
e.g. (assuming I use last example above)
A1, A2, A3
------------
01, 02, 03
04, 05, 06
07, 08, 09
B1,B2,B3 (since there is no values can be hidden)
-----------
C1,C2,C3
09, 08, 07
06, 05, 04
03, 02, 01
Would really appreciate some thoughts on this if anybody can suggest a way to do this.

Could you unpivot the data in the query?

CREATE TABLE #Test(

A1 CHAR(2),

A2 CHAR(2),

A3 CHAR(2),

B1 CHAR(2),

B2 CHAR(2),

B3 CHAR(2),

C1 CHAR(2),

C2 CHAR(2),

C3 CHAR(2)

)

INSERT INTO #Test VALUES

('01', '02', '03', '00', '00', '00', '09', '08', '07'),

('04', '05', '06', '00', '00', '00', '06', '05', '04'),

('07', '08', '09', '00', '00', '00', '03', '02', '01');

SELECT ColGroup, Col1, Col2, Col3

FROM #Test

CROSS APPLY( VALUES ('A', A1, A2, A3),

('B', B1, B2, B3),

('C', C1, C2, C3))u(ColGroup, Col1, Col2, Col3)

ORDER BY ColGroup;

GO

DROP TABLE #Test

Thank you for your response. Apologies I had not seen your response. I went down the route of using several selects joined with a union, but will give this a go also just to learn another way of doing it.
