Dealing with Incorrect Integer Insertion in MySQL: From Int to Bigint

Encountering issues with integer values not being correctly inserted into a MySQL database can be perplexing. This article seeks to shed light on this common problem, specifically addressing the issue of the incorrect integer 2147483647 being inserted instead of the intended value.

The reported issue stems from using integer type to store a value that exceeds its capacity limit. The integer data type in MySQL has a maximum value of 2147483647, as mentioned in the provided answer. When a value greater than this limit is attempted to be inserted, MySQL resorts to assigning the maximum integer value instead, leading to the incorrect value being inserted.

To resolve this issue, the solution is to alter the data type of the affected column from integer to bigint. Bigint, also known as a long integer, has a much larger value range, allowing it to accommodate larger values without sacrificing precision. By changing the column type, the database can correctly handle and store the intended value.

It is important to note that changing the data type may require altering other code and operations that rely on the previous data type. Additionally, consider the potential performance implications and data integrity constraints associated with the change.

By making the necessary adjustments to the data type, you can ensure that integer values are correctly inserted into your MySQL database, avoiding issues like the incorrect value of 2147483647 being inserted.
