String_CompareOrdinal4k

It is equivalent to String_CompareOrdinal except no NVARCHAR(MAX) parameters; it can be used when input data will never be over 4000 characters as this function offers better performance.

String_CompareOrdinal4k (
	@strA NVARCHAR (4000), 
	@strB NVARCHAR (4000)
	)
RETURNS INT

Example

SELECT SQLNET::String_CompareOrdinal4k('case', 'Case')
SELECT SQLNET::String_CompareOrdinal4k('Archæology', 'ARCHÆOLOGY')
