MySQL Insertion of Incorrect Integer: Identifying the Cause and Solution

When attempting to insert integers into a MySQL database, you may encounter instances where the inserted value unexpectedly differs from the intended input. This discrepancy can occur when the intended value exceeds the maximum integer size supported by MySQL.

In the specific scenario presented, a user is attempting to insert a Steam64 ID (identified by the variable $steam64) into the steam64 column of a MySQL table. Upon execution, they notice that the inserted integer is incorrect.

Root Cause:

The root cause of this issue lies in the maximum integer size limitations of MySQL. MySQL's default integer type, INT, has a maximum value of 2,147,483,647. Any integer larger than this will be truncated and inserted as the maximum value.

Solution:

To resolve this issue, you should modify the data type of the steam64 column to BIGINT. BIGINT supports integers with a maximum value of 9,223,372,036,854,775,807, which is sufficient for storing Steam64 IDs without truncation. The modified SQL query will resemble the following:

$sql_query = "INSERT INTO users_info (steam64) VALUES ($steam64)";
