Question

I want to search a table for all rows that contain a non-alphanumeric and non-space character in a specific field. What I have so far:

SELECT *
FROM myTable
WHERE myField LIKE '%[^a-zA-Z0-9]%'

As far as I can tell, this returns all non-alphanumeric fields. However, spaces are fine, so I don’t want to return rows where the only non-alphanumeric character is a space. How can I adjust this query?

Answer 1

How about you add the space:

SELECT *
FROM myTable
WHERE myField LIKE '%[^a-zA-Z0-9 ]%'
