Answer Source

Double negative like

  SomeCol NOT LIKE '%[^a-z]%'

Ignoring the first NOT, this means "match any character not in the range a to z".

Then, you reverse using the first NOT which means "don't match any character not in the range a to z"

Edit, after comment

LIKE '%[a-z]%' means "find any single character between a-z. So 111s222 is matched for example because s matches in this like.
