BIT_COUNT
Function statement:
BIT_COUNT(<expr> bigint|boolean)
Supported engines: SparkSQL and Presto
Usage instructions: Set
expr to an unsigned 64-bit integer and return the number of bits that are 1. If the parameter is NULL, NULL is returned.Return type:
integerExample:
> SELECT bit_count(5);2
BIT_GET
Function statement:
BIT_GET(<expr> bigint|boolean, <pos> integer)
Supported engines: SparkSQL and Presto
Usage instructions: Return the value of the bit at the specified position (0 or 1). Positions are numbered from right to left, starting at zero. The position parameter cannot be negative.
Return type:
integerExample:
> SELECT bit_get(11, 0);1> SELECT bit_get(11, 2);0
GETBIT
Function statement:
GETBIT(<expr> bigint|boolean, <pos> integer)
Supported engines: SparkSQL and Presto
Usage instructions: Return the value of the bit at the specified position (0 or 1). Positions are numbered from right to left, starting at zero. The position parameter cannot be negative.
Return type:
integerExample:
> SELECT getbit(11, 0);1> SELECT getbit(11, 2);0
