Exclusive disjunction: xor

Syntax

op1 xor op2

Input parameters

op1	the first operand
op2	the second operand

Examples of valid syntaxes

DS_1 xor DS_2

Semantics for scalar operations

The xor operator returns TRUE if only one of the operand is TRUE (but not both), FALSE otherwise. The two operands must be of boolean type. For example: | FALSE xor FALSE gives FALSE | FALSE xor TRUE gives TRUE | FALSE xor NULL gives NULL | TRUE xor FALSE gives TRUE | TRUE xor TRUE gives FALSE | TRUE xor NULL gives NULL | NULL xor NULL gives NULL

Input parameters type

op1, op2

dataset {measure<boolean> _ }
| component<boolean>
| boolean

Result type

result

dataset {measure<boolean> _ }
| component<boolean>
| boolean

Additional Constraints

None.

Behaviour

The operator has the typical behaviour of the “Behaviour of Boolean operators” (see the section “Typical behaviours of the ML Operators”).

Examples

Given the operand datasets DS_1 and DS_2:

Input DS_1 (see structure)

Id_1	Id_2	Id_3	Id_4	Me_1
M	15	B	2013	True
M	64	B	2013	False
M	65	B	2013	True
F	15	U	2013	False
F	64	U	2013	False
F	65	U	2013	True

Input DS_2 (see structure)

Id_1	Id_2	Id_3	Id_4	Me_1
M	15	B	2013	False
M	64	B	2013	True
M	65	B	2013	True
F	15	U	2013	True
F	64	U	2013	False
F	65	U	2013	False

Example 1

DS_r:=DS_1 xor DS_2;

results in (see structure):

DS_r
Id_1	Id_2	Id_3	Id_4	Me_1
M	15	B	2013	True
M	64	B	2013	True
M	65	B	2013	False
F	15	U	2013	True
F	64	U	2013	False
F	65	U	2013	True

Example 2

DS_r:= DS_1 [ calc Me_2:= Me_1 xor true ];

results in (see structure):

DS_r
Id_1	Id_2	Id_3	Id_4	Me_1	Me_2
M	15	B	2013	True	False
M	64	B	2013	False	True
M	65	B	2013	True	False
F	15	U	2013	False	True
F	64	U	2013	False	True
