I have 3 or 4 entries with the same name of a person an different other entries.
A B C
---- ---- -----------
a 01 XXX
a 02 XYZ
a 03 ABC
How can I merge them by selecting the a which is always the same in A to a structure like this:
A B C D E F G
--- --- --- --- --- --- ---
a 01 02 03 XXX XYZ ABC
Hope you can help me getting this.
Alternative Solution
If you have variable number of entries for different users then use GROUP_CONCAT FUNCTION. It is easier way (with some processing in php) than to make dynamic number of columns in sql.
SELECT A,GROUP_CONCAT(B) B, GROUP_CONCAT(C) C
FROM TABLE
GROUP BY A;
The result will be like:- ABC
--- --- --- a 01,02,03 XXX,XYZ,ABC
You can further process it in php code to get column separated.
