Describe the bug

Fatal error: Uncaught TypeError: bccomp() expects parameter 1 to be string, int given in phar:///home/container/virions/libasynql.phar/src/poggit/libasynql/mysqli/MysqliThread.php:186
Stack trace:

Sample code

-- # 			{ pre_registered
-- # 			  :username string
SELECT record_id
FROM pre_registered
WHERE username = :username
LIMIT 1;
-- # 			}

Expected behavior

record_id is a unsigned bigint, the error didn't occur when no result is selected

Environment

OS: linux and idk other stuffs (Same result on Windows10)
PocketMine version: 3.14.2
Libasynql version: 3.3.1

[Endermanbugzjfc]

Somehow fixed by setting record_id to unsigned int

This seems a bug indeed.

Hi, I had the same problem today. Why is it necessary to manage precision? We shouldn't worry as we are using PHP 64-bit.

Otherwise we need to use CONVERT function or use GMP extension but I don't think it's included in PocketMine binaries files.

[matcracker]

However, there would be a problem, int casting is not possible. We must therefore transform the value into a float.

[SOF3]

unsigned longs?
