MySQL EXPORT_SET() Function

The MySQL EXPORT_SET() function returns a string which contains an on string for every bit set in the value bits, and an off string for every unset bit in the value bits.

Bits in bits are examined from right to left (from low-order to high-order bits). Strings are added to the result from left to right, separated by the separator string (the default being the comma character ,). The number of bits examined is given by number_of_bits, which has a default of 64 if not specified. number_of_bits is silently clipped to 64 if larger than 64. It is treated as an unsigned integer, so a value of −1 is effectively the same as 64.

Syntax

EXPORT_SET(bits, on, off, separator, number_of_bits)

Parameters

Return Value
