How to deal with MySQL connection error 1364?

MySQL connection error 1364 refers to a field value mismatch error that occurs when inserting data into the MySQL database. It means that the field value to be inserted cannot find the corresponding field in the database table.

So, how should we deal with this error? Some solutions are given below.

First, we need to confirm the specific information of the error. When connection error 1364 occurs, MySQL will prompt specific error information, which may include incorrect table names and field names. By carefully reading the error message, we can better locate the problem.

Next, we need to check the correctness of the insert statement. Usually, connection error 1364 is caused by the inserted data not matching the table structure. We can confirm whether the inserted data contains all required fields by checking the structure of the table. If not, we need to modify the insert statement to ensure that all required fields have values. In addition, you should also pay attention to whether the data type of the field is consistent with the table structure. For example, inserting a string value into an integer field will cause connection error 1364 to occur.

In addition, we must also pay attention to MySQL's strict mode settings. In strict mode, MySQL will check the matching of field values ​​more strictly. If we do not encounter connection error 1364 when developing in non-strict mode, but this error occurs when publishing to the official environment, it is most likely because the official environment has strict mode turned on. In order to solve this problem, we can turn off strict mode by modifying the MySQL configuration file. Specific methods can be found in the MySQL official documentation.

In addition, we can also use default values ​​or triggers to handle connection error 1364. If the data we insert lacks values ​​for some fields, but default values ​​for these fields are defined in the table structure, MySQL will automatically insert the default values ​​into these fields. If no default values ​​are set, we can consider using triggers to automatically fill in missing field values ​​before inserting data. Triggers are a powerful mechanism provided by MySQL that can perform specified actions before and after insert, update, delete and other operations.

Finally, we can also consider using the ALTER TABLE statement to modify the table structure. If we find that the field to be inserted does not match the table structure, but we do not want to modify the insert statement, we can add or delete fields through the ALTER TABLE statement to adapt to the requirements of inserting data.

In short, dealing with MySQL connection error 1364 requires us to read the error message carefully, check the correctness of the insert statement, pay attention to MySQL's strict mode settings, use default values ​​or triggers to handle missing field values, and use ALTER The TABLE statement modifies the table structure. Through these methods, we can better handle MySQL connection error 1364 and ensure that our data can be inserted into the database normally.
