dbForge Data Compare for MySQL offers you a perfect opportunity to compare data between different databases with many useful features. They include the following:
By default data comparison is performed only for the objects with the same names and owners. Process of choosing corresponding database objects in source and target for comparison is called object mapping. You can use Data Compare for MySQL automatic mapping or map database objects manually. Data Compare for MySQL allows you to customize mapping of tables (views) and columns, so you can compare data of objects with non-equal names, owners, and structure. For more information, see Object Mapping.
The following tables and views cannot be compared:
By default, data is compared by a primary or unique key, but other key or custom column set can be defined. A comparison key is used to determine which rows correspond to each other. It is not recommended to use a non-unique comparison key. If the table does not have a suitable key, you should manually select a custom key for this table when comparing. You should always set a custom key for views when comparing data with the Compare Views check box selected.
Data comparison can be saved to the file and opened later.
