Bit Value Type
suggest changeThe 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.
