BIT_SET
Applies to ✅ Open Source Edition ✅ Express Edition ✅ Professional Edition ✅ Enterprise Edition
The BIT_SET() function sets the bit value at a given position to a new value:
SELECT bit_set(3, 0), bit_set(3, 2), bit_set(3, 0, 0), bit_set(3, 2, 1);
create.select( bitSet(inline(3), 0), bitSet(inline(3), 2), bitSet(inline(3), 0, 0), bitSet(inline(3), 2, 1)).fetch();
The result being
+---------+---------+---------+---------+ | bit_set | bit_set | bit_set | bit_set | +---------+---------+---------+---------+ | 3 | 7 | 2 | 7 | +---------+---------+---------+---------+
