Actually, Bit values are returned as binary values but we can also display them in the printable form with the help of following −
By adding 0
We can display Bit values in printable form by adding 0 to them. Following the example from the bit_testing table can be used to understand it −
mysql> Select bittest+0 from bit_testing; +-----------+ | bittest+0 | +-----------+ | 170 | | 5 | | 5 | +-----------+ 3 rows in set (0.00 sec)
By using conversion function BIN(),OCT(),HEX()
We can also display Bit values in printable form by using BIN() conversion function. Following the example from the bit_testing table can be used to understand it −
mysql> Select BIN(bittest+0) from bit_testing; +----------------+ | BIN(bittest+0) | +----------------+ | 10101010 | | 101 | | 101 | +----------------+ 3 rows in set (0.00 sec) mysql> Select OCT(bittest+0) from bit_testing; +----------------+ | OCT(bittest+0) | +----------------+ | 252 | | 5 | | 5 | +----------------+ 3 rows in set (0.05 sec) mysql> Select HEX(bittest+0) from bit_testing; +----------------+ | HEX(bittest+0) | +----------------+ | AA | | 5 | | 5 | +----------------+ 3 rows in set (0.00 sec)
