Creating a MySQL SET's from a string

Question

Is there a way to create a set from a string of separated values in MySQL? For example:

\'the,quick,brown,fox\' => \'the\',\'quick\',\'brown\',\'fox\'

Answer 1

If you're trying to use the set in an IN statement, instead of splitting the string, you could do a comparison like:

SELECT * FROM `table` WHERE 'the,quick,brown,fox' REGEXP CONCAT('(^|,)','word','(,|$)');

I'm not sure how efficient this would be if your dataset is large, but it might be faster than reading into and selecting from a temporary table.
