Why Does My MySQL Database Truncate My SteamID64, and How Can I Fix It?

MySQL Integer Precision Limitation:

The Steam Web API provides a 64-bit integer known as $steam64. When inserting this value into a MySQL database using the query INSERT INTO users_info (steam64) VALUES ('$steam64'), you encounter a discrepancy between the value stored in the variable and the value inserted into the database.

This is because MySQL has a precision limit for integer types. The maximum integer value that can be stored in an integer column is 2,147,483,647. Since the $steam64 value exceeds this limit, MySQL truncates it to the largest allowed value, which is 2,147,483,647.

Solution:

To resolve this issue, change the column type from INT to BIGINT. BIGINT can store integers up to 9,223,372,036,854,775,807, which is sufficient for 64-bit integers.

Modify the table definition to include the following change:

ALTER TABLE users_info MODIFY COLUMN steam64 BIGINT;

After making this change, the query will insert the correct 64-bit $steam64 value into the database.
