This error occurs when a column has no default value and no value is specified when inserting a new row. It is a MySQL 1230 error code and the literal message is "Column '%s' has no default value".

How It Affects Your App

MySQL 1230 ER_NO_DEFAULT can have a significant impact on an application. It indicates that a default value was not specified for a column in a table. This can lead to unexpected behavior when inserting data into the table, as the default value will not be applied. It can also lead to data integrity issues, as the data may not be consistent with the expected format. Furthermore, it can cause errors when attempting to query the table, as the query may not be able to find the data it is expecting.
