BIT |
BITSTRING |
variable-length strings of 1s and 0s |
Bitstrings are strings of 1s and 0s. The bit type data is of variable length. A bitstring value requires 1 byte for each group of 8 bits, plus a fixed amount to store some metadata.
By default bitstrings will not be padded with zeroes.
Bitstrings can be very large, having the same size restrictions as BLOBs.
-- Create a bitstring
SELECT '101010'::BIT;
-- Create a bitstring with predefined length.
-- The resulting bitstring will be left-padded with zeroes.
-- This returns 000000101011.
SELECT bitstring('0101011', 12);
Functions
See Bitstring Functions.
