I have a ref no. column that includes all types of formatting. I'd like to include only ref.no that have a format of xx-xxxx. I currently have
inv.ReferenceNumber LIKE '%-%'
However, I have Ref No.'s with formats x-xxxxx and xxxxx-xx. Is there a way where I can filter having results as xx-xxxx?
Underscore matches exactly one character.
So
where inv.ReferenceNumber LIKE '__-____'
