I want to create a table which contains a field with multiple values. I familiar with the "set" type, but the problem is that I don't know exactly all the value in advanced.

Does anyone know a solution?

Thanks

You can put them as comma-separated values (strings) in the column, and use the find_in_set function to query (in case you want to).

ADD:

You could later query as shown below:

For instance, to search for all rows which have value1 as a value in that column, use this:

SELECT T1.column
FROM Table T1 
WHERE find_in_set('value1', T1.column) > 0;
