Bit Value Type

suggest change

The BIT type is useful for storing bit-field values. BIT(M) allows storage of up to M-bit values where M is in the range of 1 to 64

You can also specify values with bit value notation.

b'111'      -> 7
b'10000000' -> 128

Sometimes it is handy to use ‘shift’ to construct a single-bit value, for example (1 << 7) for 128.

The maximum combined size of all BIT columns in an NDB table is 4096.
