Subject: LP#1996651: treat empty string as null for preferred name/alias in wide_hold_data
X-Git-Url: https://old-git.evergreen-ils.org/?a=commitdiff_plain;h=ee8ff0fd49e4849752da80461e7e8b828084fc77;p=Evergreen.git

LP#1996651: treat empty string as null for preferred name/alias in wide_hold_data

This prevents the patron name from appearing blank in the hold shelf
"User Display Name" or "User Alias or Display Name" columns when the
alias or preferred name fields are empty strings.
