BIT_ XOR

Performs an XOR function on corresponding pairs of bits (i.
Since BIT_
is an aggregate function, it can be used with the GROUP BY
clause.
May be used as a window function.
Syntax
Aggregate Function
BIT_XOR (<expr1>, <expr2>)
Window Function
BIT_XOR(col | expr) OVER (
[PARTITION BY (col | expr), ...]
[ORDER BY (col | expr), ...]
Arguments
-
expression: expressions must be integer data types.
Return Type
This will result in a one if two of the corresponding bits are different.
Examples
Aggregate Function
CREATE TABLE ba_numeric_sample (group_name varchar(10), ltr_val int);INSERT INTO ba_numeric_sample VALUES('alpha', 111), ('beta', 110), ('gamma', 000), ('delta', 001);
SELECT group_name, BIT_XOR(001) FROM ba_numeric_sample GROUP BY group_name;
