Why is MySQL Storing 2147483647 Instead of My Large Integer Value?

MySQL Importing Incorrect Integer: 2147483647

When trying to insert a significant integer into a MySQL database, users may encounter a peculiar issue where a different number is stored than the one intended. To delve into the solution, let's explore the provided code snippet:

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

It attempts to insert the value stored in the variable $steam64 into a database column named steam64. However, users report that the inserted value differs from the one held in $steam64. The root cause of this issue lies in the data type of the steam64 column. In MySQL, the default data type for integers is INT, which can store values ranging from -2,147,483,648 to 2,147,483,647.

In this case, the value being inserted (2147483647) exceeds the maximum value that can be held by an INT data type. As a result, MySQL automatically converts the value to the largest integer it can accommodate, which is 2147483647.

To resolve this issue, the data type of the steam64 column must be changed to BIGINT. This data type has a larger range of supported values and can comfortably accommodate the value of 2147483647 without any truncation or conversion. Once the data type is modified, the correct value will be inserted into the database.
