All,

I'm wondering if this is a MySQL bug, but since I've seen others playing with larger numbers than this, I'm thinking I'm doing something wrong here.

Here is my table structure for the table I'm querying: mysql> describe ipspace6\G ************* 1. row ************* Field: id Type: decimal(39,0) unsigned Null: NO Key: Default: NULL Extra: ************* 2. row ************* Field: addr Type: decimal(39,0) unsigned Null: NO Key: PRI Default: 0 Extra: ************* 3. row ************* Field: netmask Type: decimal(39,0) unsigned Null: NO Key: Default: 0 Extra: ************* 4. row ************* Field: subnet Type: int(4) Null: NO Key: Default: NULL Extra:

Now, I run a simple SELECT statement against the "id" column:

mysql> SELECT id FROM ipspace6 WHERE id='50552019118453823914642686339427860480'; +----------------------------------------+ | id | +----------------------------------------+ | 50552019118453823730175245602332344320 | | 50552019118453823730175245602332344320 | | 50552019118453823914642686339427860480 | | 50552019118453823914642686339427860480 | +----------------------------------------+

...What the heck is going on here? Two of these results are valid, and two definitely are not.

It's not like I'm doing some super-complex nested query or anything, this is simple stuff, and it's driving me insane.

Help, anyone?
