Question

Consider a table that looks like this:

**************************
* Col1 *** Col2 *** Col3 * 
--------------------------
*  0   ***  1   ***  0   *
*  0   ***  0   ***  0   *
*  1   ***  1   ***  0   *
*  1   ***  1   ***  1   *
**************************

How could I join (for example) the last row with each field containing “1” translated into something?

So for the first row, it would return something like: “Yes” (omitting the ones that isn’t “1”). Or for the last row: “Yes, Yes, Yes”.

Answer 1

SELECT IF(Col1=1,'Yes', 'No'), IF(Col2=1,'Yes', 'No'), IF(Col3=1,'Yes', 'No') FROM tbl;

Replace 'NO' with 0 if you don’t want No.

ANSWER MODIFICATION TO REFLECT QUESTION:

SELECT CONCAT_WS(',', IF(Col1=1,'Yes',NULL), IF(Col2=1, 'Yes', NULL), IF(Col3=1, 'Yes', NULL) ) as formatedText FROM tbl;
