(SQL Server 2016 introduced the built-in function STRING_SPLIT. Its behavior is not identical to SoftadminUtil.String_Split so you can not simply replace calls to one with the other, but you should consider writing new code using the built-in function.)
Splits the supplied string into several substrings at a specific character or sequence of characters. Each substring is returned on a separate row in the resultset.
If the supplied value is an empty string then a single row with the value null is returned.
If the supplied value is null then no rows are returned.
