How to resolve the error of setting default values in Navicat?

To resolve the error of setting default values in Navicat, you can try the following steps:

1. Check the database table structure to ensure that there are no errors or missing required fields.
2. Check the default value settings: ensure that the default values set meet the requirements of the database field types, such as using single quotation marks when setting a default value for a string type.
3. The field type should be checked to ensure the correct database field type is used, for example, setting a default value as a string type when the field type is actually an integer type.
4. Check field length: if the length of the default value set exceeds the maximum length of the field, an error may occur, so ensure that the length of the default value does not exceed the maximum length defined for the field.
5. Check the database version: Some database versions may have bugs that cause errors when setting default values. You can try upgrading the database version or using a different database management tool to make the setting.
6. Check permissions: Make sure you have sufficient privileges to set default values, as certain databases may require specific permissions to do so.
7. Check error message: Examine the specific error message provided, as it often offers useful tips to make the necessary adjustments and fixes.

If the above steps do not solve the issue, you can try reinstalling Navicat or contacting Navicat’s official technical support for consultation and resolution.
