MySQL 140

This error occurs when a user attempts to set a precision value for a column that is greater than the maximum allowed value of 65.

How It Affects Your App

This error occurs when a user attempts to store a value with a precision that is too large for the column. This can cause the application to malfunction, as the data will not be stored correctly. It can also lead to data corruption, as the data will not be stored in the correct format. Additionally, it can lead to unexpected results when the data is retrieved from the database, as the data will not be in the expected format.
