SELECT only rows that contain only alphanumeric characters in MySQL

Question

I\'m trying to select all rows that contain only alphanumeric characters in MySQL using:

SELECT * FROM table WHERE column REGEXP \'[A-Za-z0-9]\';
         


        

Answer 1

There is also this:

select m from table where not regexp_like(m, '^[0-9]\d+$')

which selects the rows that contains characters from the column you want (which is m in the example but you can change).

Most of the combinations don't work properly in Oracle platforms but this does. Sharing for future reference.
