BIGINT UNSIGNED VALUE IS out of range My SQL

Question

I\'m getting the following error

#1690 - BIGINT UNSIGNED value is out of range in \'(legends.spawns.quantity -

Answer 1

I had the same problem, it occurred on a JOIN and couldn't figure out what was going on, in the end it was typo in the ON clause where I placed a minus sign instead of an equal sign. Might be stupid but I just didn't see it for about 30 minutes and maybe this could help someone!!!

Answer 2

I actualy found that question why I was searching for solution. If you have same problem as I do, try disabling "unsigned" parameter.

It is quite possible that your code fails here:

(
quantity - COUNT( game_moblist.spawn_id )
)

because if result of that matematic operation is less than zero it will fail with "unsigned" parameter.

Answer 3

sql_mode worked in the MySQL client and Adminer, but not in CodeIgniter, where it counts. Casting didn't help either.

A simple arithmetic operation did the trick:

error

id - id_ex*1000000000 = id_sm

works

id_sm + id_ex*1000000000 = id

Answer 4

I don’t quite understand why everyone is saying unsigned. I have a special value in sql and also reported this error. I did it by converting this value to decimal.

cast(1000000000000000000 AS DECIMAL ( 35, 2 ))

Answer 5

To generalise the rule, MySQL will now refuse to substract an UNSIGNED operand from a SIGNED one.

Example : SELECT A - B; will fail if A is SIGNED whereas B is UNSIGNED.

Workarounds: Add 1.0 factor to the signed operand, so it implicitly casts it to FLOAT, or use CAST (B AS SIGNED), or even swap (B - A) and change the algorithm accordingly.

Answer 6

I had similar problem, This error also come if our column have 0 value and we try to update it with -1 value.

In my case MySQL query were Failing if column1 is already have value 0, i.e column1 = 0

For example:

UPDATE `table1` SET `column1` = `column1` - 1 WHERE `column2` = XYZ

This give error

BIGINT UNSIGNED value is out of range in ....

To counter this problem

UPDATE `table1`
SET `column1` = (
    CASE WHEN `column1` < 1
    THEN 0
    ELSE (`column1` - 1)
end)
WHERE `column2` = 1
LIMIT 1
