T-SQL XOR Operator

Question

Is there an XOR operator or equivalent function in SQL Server (T-SQL)?

Answer 1

<> is generally a good replacement for XOR wherever it can apply to booleans.

Answer 2

The xor operator is ^

For example: SELECT A ^ B where A and B are integer category data types.

Answer 3

It is ^ http://msdn.microsoft.com/en-us/library/ms190277.aspx

Answer 4

Using boolean algebra, it is easy to show that:

A xor B = (not A and B) or (A and not B)


A B | f = notA and B | g = A and notB | f or g | A xor B    
----+----------------+----------------+--------+--------    
0 0 | 0              | 0              | 0      | 0    
0 1 | 1              | 0              | 1      | 1    
1 0 | 0              | 1              | 1      | 1    
1 1 | 0              | 0              | 0      | 0

Answer 5

There is a bitwise XOR operator - the caret (^), i.e. for:

SELECT 170 ^ 75

The result is 225.

For logical XOR, use the ANY keyword and NOT ALL, i.e.

WHERE 5 > ANY (SELECT foo) AND NOT (5 > ALL (SELECT foo))

Answer 6

MS SQL only short form (since SQL Server 2012):

1=iif( a=b ,1,0)^iif( c=d ,1,0)
