how can do this in mysql ?
If it is not possible pls suggest a better structure for this need. Every month the caption may be changed.

Answer 1

I suggest the following table structure:

CREATE TABLE B (
  add varchar(10) PRIMARY KEY,
  caption varchar(50)
);
CREATE TABLE A (
  add varchar(10) PRIMARY KEY,
  value int
);

Then use this query:

SELECT caption, value
FROM A INNER JOIN B
ON A.add = B.add

But if you want to keep your table structure, you can do:

SELECT B.add1 Caption, A.add1 Value
FROM A, B
UNION ALL
SELECT B.add2, A.add2
FROM A, B
UNION ALL
SELECT B.add3, A.add3
FROM A, B
