Can Mysql Split a column?

Use

substring_index(`column`,',',1) ==> first value
substring_index(substring_index(`column`,',',-2),',',1)=> second value
substring_index(substring_index(`column`,',',-1),',',1)=> third value

in your where clause.

SELECT * FROM `table`
WHERE 
substring_index(`column`,',',1)<0 
AND
substring_index(`column`,',',1)>5

It seems to work:

substring_index ( substring_index ( context,',',1 ), ',', -1) 
substring_index ( substring_index ( context,',',2 ), ',', -1)
substring_index ( substring_index ( context,',',3 ), ',', -1)
substring_index ( substring_index ( context,',',4 ), ',', -1)

it means 1st value, 2nd, 3rd, etc.

Explanation:

The inner substring_index returns the first n values that are comma separated. So if your original string is "34,7,23,89", substring_index( context,',', 3) returns "34,7,23".
The outer substring_index takes the value returned by the inner substring_index and the -1 allows you to take the last value. So you get "23" from the "34,7,23".
Instead of -1 if you specify -2, you'll get "7,23", because it took the last two values.

Example:

select * from MyTable where substring_index(substring_index(prices,',',1),',',-1)=3382;

Here, prices is the name of a column in MyTable.

Usually substring_index does what you want:

mysql> select substring_index("[email protected]","@",-1);
+-----------------------------------------+
| substring_index("[email protected]","@",-1) |
+-----------------------------------------+
| gmail.com                               |
+-----------------------------------------+
1 row in set (0.00 sec)

You may get what you want by using the MySQL REGEXP or LIKE.
