MySQL BIT Variable Type Altering Data

Question

I have a table with two columns and two variable types.

CATEGORY VARCHAR(64)

HASH BIT(49)

I'm using a php page to insert new values each time they are found.

Here is an example insertion statement:

INSERT INTO `HASH` (HASH, CATEGORY) VALUES (0b1001010010110101011100111000101000010100001110001, 'foo');

The query executes fine, but here's the problem.

Now, when I look in my database, the 'foo' hash value is this:

1001100100011011100110000001100010011010000110000

When the original value was:

1001010010110101011100111000101000010100001110001

Why is this? And how can I fix it?

Answer 1

The error must be located somewhere else.

The code works. See this SQLFiddle example .
