Problem with IN()

Problem with IN()

Problem with IN()

(OP)
I've stored lists of numbers in columns, that looks like this:
1,2,6,7
I've chosen varchar(255) to store these values. Let's call this column "numbers".

Now, I want to find out which rows holds a certain number. So, these two query should both return 1, right?

Query 1: SELECT 6 IN(1,2,6,7);
Query 2: SELECT 6 IN(numbers) FROM my_table;

The problem is that MySQL seems to interpret the second query like this:
SELECT 6 IN('1,2,6,7') FROM my_table;
...since "1,2,6,7" is stored as a string, so it doesn't work.

How can I make MySQL understand that I want it to be interpreted like QUERY 1?

RE: Problem with IN()

Try

SELECT * FROM your_table WHERE the_column LIKE "%the_number%"

I hope it works...

RE: Problem with IN()

(OP)
I forgot to mention that the numbers will not always be one-digit.
But that's okay, 'cause I fixed it through the amazing powers of regular expressions, yaay!

SELECT * FROM my_table WHERE  numbers REGEXP "(^|,)6(,|$)";
