MySQL Split String Function
http://blog.fedecarg.com/2009/02/22/mysql-split-string-function/MySQL does not include a function to split a delimited string. However, it’s very easy to create your own function.
Create function syntax
A user-defined function is a way to extend MySQL with a new function that works like a native MySQL function.
CREATE FUNCTION function_name
RETURNS {STRING|INTEGER|REAL|DECIMAL}
To create a function, you must have the INSERT privilege for thedatabase.
Split delimited strings
The following example function takes 3 parameters, performs an operation using an SQL function, and returns the result.
Function
CREATE FUNCTION SPLIT_STR( x VARCHAR(255),
delim VARCHAR(12),
pos INT
)
RETURNS VARCHAR(255)
RETURN REPLACE(SUBSTRING(SUBSTRING_INDEX(x, delim, pos),
LENGTH(SUBSTRING_INDEX(x, delim, pos -1)) + 1),
delim, '');
Usage
SELECT SPLIT_STR(string, delimiter, position) Example
SELECT SPLIT_STR('a|bb|ccc|dd', '|', 3) as third;
+-------+
| third |
+-------+
| ccc |
+-------+
