For example, `SELECT BIT_COUNT (CAST (-1 AS SMALLINT))` and `SELECT BIT_COUNT (CAST (-1 AS INT))` return `16` and `32` respectively. This is intended, as the binary representation of `-1` can have a different number of bits set to `1` depending on the data type.

If *expression_value* is `NULL`, `BIT_COUNT` returns `NULL`.

## Remarks

Distributed Query functionality for the bit manipulation functions within linked server or ad hoc queries (`OPENQUERY`) aren't supported.
