Question

Lets say I have a table as follows,

+----+-------------+
| id | value       |
+----+-------------+
| 1  | aa,bb,cc,dd |
| 2  | ee,ff,gg,hh |
+----+-------------+

I want to be able to search this table to see if id = 1 AND value = 'cc'.
Im assuming a good way of doing this is to grab the id = 1 row and split its values into separate rows in a new view. Something like,

+-----+
| val |
+-----+
| aa  |
| bb  |
| cc  |
| dd  |
+-----+

I would like to do all of this in MySQL. How can i do this, and is there possibly a better way to do it?

This article might help you solve the problem:

Mysql split column string into rows

Instead of this:

DECLARE cur1 CURSOR FOR 
          SELECT table1.id, table1.value
          FROM table1
          WHERE table1.value != '';

try this to fit your needs,

DECLARE cur1 CURSOR FOR 
          SELECT id, value
          FROM table1
          WHERE id = 1;
