SQL - Integer Type - Detect bit

Say you're checking for the 3rd bit then...

SELECT bits & 8 = 8 FROM table;

This returns a binary (1 or 0) for whether the bit in question (in this case the third) is on or off for each row in the column 'bits'.

using 2^x for the xth bit instead of 8.

for example, to check the 5th bit we would use 2^5 = 32

SELECT bits & 32 = 32 FROM table;

However, this is needlessly complicated. Simply use boolean values in several columns and it will make things much easier.

Use &, the bitwise AND operator:

SELECT ID, myfield
FROM mytable
WHERE (myfield & 16) > 0
