Is there something analogous to a split() method in mySql?

Question

I\'m looking to write a stored procedure that takes as a parameter a string that\'s delimited by a token and then to run a while loop in the procedure for every item in that str

Answer 1

I think you'll need to roll your own function. substring_index will come in handy:

SUBSTRING_INDEX(str,delim,count)

Returns the substring from string str before count occurrences of the delimiter delim. If count is positive, everything to the left of the final delimiter (counting from the left) is returned. If count is negative, everything to the right of the final delimiter (counting from the right) is returned. SUBSTRING_INDEX() performs a case-sensitive match when searching for delim.

mysql> SELECT SUBSTRING_INDEX('www.mysql.com', '.', 2);
        -> 'www.mysql'
mysql> SELECT SUBSTRING_INDEX('www.mysql.com', '.', -2);
        -> 'mysql.com'

This function is multi-byte safe.
