Question

I have the following table:

 CodeName    cnt             cnt
CodeNAmeA   1111            2222
CodeNAmeB   3333            4444
CodeNAmeC   5555            6666

This table is the result of the following query:

(select a.CodeName, a.cnt, b.cnt from

  (select tableA.CodeName, count(*) cnt
   from aaaa..AAAA tableA inner join bbbb..BBBB tableB 
   on tableA.CodeName = tableB.CodeName
   where XXXXXXX
   group by tableA.CodeName) a

   JOIN

  (select tableA.CodeName, count(*) cnt
   from aaaa..AAAA tableA inner join bbbb..BBBB tableB 
   on tableA.CodeName = tableB.CodeName
   where XXXXXXX
   group by tableA.CodeName,tableA.INAMALOCK) b

ON a.CodeName = b.CodeName) 

I have another table like this:

 CodeName        RealName
CodeNAmeA       RealNameA
CodeNAmeB       RealNameB
CodeNAmeC       RealNAmeC

This table is the result of a simple select query

select CodeName
from TableCodeReal

What I want to do is show the folowing:

 RealName    cnt     cnt
RealNameA   1111    2222
RealNameB   3333    4444
RealNameC   5555    6666

The problem comes that I don’t have the real name in the aaaa..AAAA or bbbb..BBBB, how do I get the result of the first query and do the replacement?. Thank very much, I get very confused about how to integrate the second table in the first query.

Answer 1

I believe this is what you require.
Make your main query a sub query and join onto your second table on the CodeName value. Then select the RealName from your second table, along with your cnt values (which I have aliased as acnt and bcnt).

SELECT T.RealName, Q.acnt, Q.bcnt
FROM
(select a.CodeName, a.cnt as acnt, b.cnt as bcnt from

  (select tableA.CodeName, count(*) cnt
   from aaaa..AAAA tableA inner join bbbb..BBBB tableB 
   on tableA.CodeName = tableB.CodeName
   where XXXXXXX
   group by tableA.CodeName) a

   JOIN

  (select tableA.CodeName, count(*) cnt
   from aaaa..AAAA tableA inner join bbbb..BBBB tableB 
   on tableA.CodeName = tableB.CodeName
   where XXXXXXX
   group by tableA.CodeName,tableA.INAMALOCK) b

ON a.CodeName = b.CodeName) Q
INNER JOIN TableCodeReal T ON Q.CodeName = T.CodeName
