|MySQL selecting only alnum etc|
I am trying to create a MYSQL query that selects a title from the table only if that title is made up of the following characters:
a-z A-Z 0-9 hypens spaces underscores
If there is any other kind of character in the title, then the record is not selected.
select title from tbl_books where title REGEXP '^[[:alnum:][.space.][.hyphen.][.underscore.]]';
** The above query gives me titles that include commas,periods, etc.
Would you have an idea how I might construct the query?
SELECT title FROM tbl_books WHERE NOT title REGEXP '[^a-zA-Z0-9_ -]';
should do it.
