Use Navicat to compare and synchronize structure

By John Doe December 25, 2023

Summary: Navicat compares objects between two databases and/or schemas and states the differences in structure, and synchronize the table structures and other objects.

About Structure Synchronization

Navicat allows you to compare and modify the table structures and other objects with detailed analytical process. In other words, Navicat compares objects between two databases and/or schemas and states the differences in structure. To open the Structure Synchronization window, choose Tools -> Structure Synchronization from the menu bar.

You can save your settings as a profile for future use. To open a saved profile, click the Load Profile button and select a profile from the list.

HINT: Profiles are saved under the Profiles Location.

NOTE: Available only for MySQL, Oracle, PostgreSQL, SQL Server and MariaDB. Navicat Premium and Navicat for MySQL support synchronizing between MySQL and MariaDB.

View Structure Comparison Results

After comparing structures, the tree view shows the differences between the source and target databases or schemas. All objects are checked in the tree view by default. Uncheck the objects you do not want to apply to the target. You can expand the table objects to view the detailed structure.

You can choose to group the objects in the tree views by object types or operations by selecting Group by object type or Group by operation.

Operation Description
Modify Object exists in both source and target databases/schemas, but they have different definition. The target object will be modified based on the source object.
Create Object does not exist in the target database/schema. It will be created in the target.
Delete Object does not exist in the source database/schema. The target object will be deleted.
No Operation Object exists in both source and target databases/schemas and they have identical definition. No operation will be applied.

When you selected an object in the tree view, the DDL Comparison tab shows the DDL statements of that object in the source and the target, and the Deployment Script tab shows the detailed SQL statements of the object that will be executed in the target databases.

You can view all scripts that will be executed in the target database in the Deployment Script tab.
