There are several ways to handle null values in API PUT data requests when updating the MySQL database:
Set defaults: You can specify default values for the table columns that allow null values. When a NULL value is received in the PUT request, the default value is used instead.
Check for null values: Before processing the data, you can check if any of the values being updated are null. If they are, you can decide whether to set a default value, ignore the field, or raise an error.
Use conditional statements: You can use a conditional statement in your update query to check if a field value is null before attempting to update it. If it is null, you can skip that field or use a default value.
Use a JSON schema: You can define a JSON schema that specifies the expected data structure and constraints for the PUT request. This can include validation rules for null values.
Use PATCH instead of PUT: Instead of using PUT to update the entire record, you can use PATCH to update only specific fields. This can help avoid null values being sent for fields that should not have them.
It is recommended to use a combination of these approaches depending on the specific use case and requirements.
