BIT_
On this page
Performs an OR operation on each bit between expressions.
SinceBIT_ is an aggregate function, it can be used with the GROUP BY clause.
May be used as a window function.
Syntax
Aggregate Function
BIT_OR (<expr1>, <expr2>)
Window Function
BIT_OR(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
