Question

I have a bunch url that has a string either has

hotel+4 digit number: hotel1234 
or slash+4digit.html: /1234.html

Is there a regex to extract

Answer 1

You can try the REGEXP

SELECT * FROM Table WHERE ColumnName REGEXP '^[0-9]{4}$'

or

SELECT * FROM Table WHERE ColumnName REGEXP '^[[:digit:]]{4}$';
