A 32-bit signed integer that indicates the lexical relationship between the two comparands.

Value Condition

Zero strA occurs in the same position as strB in the sort order.
Greater than zero strA follows strB in the sort order.

Example

String_Compare4k

It is equivalent to String_Compare 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_Compare4k (
	@strA NVARCHAR (4000), 
	@strB NVARCHAR (4000)
	)
RETURNS INT

Example

SELECT SQLNET::String_Compare4k('abc', 'abc')
