Here is an example of how you would select data based on a regular expression.

SELECT phone FROM table WHERE phone REGEX '^[0-9 ]{11,14}$' = 0 LIMIT 100

The above would show all the phone numbers that are not between 11 and 14 numbers and spaces.

SELECT phone FROM table WHERE phone REGEX '^[0-9 ]{11,14}$' LIMIT 100

The above would show all the phone numbers that are between 11 and 14 numbers and spaces.

I hope this quick guide has helped.
