Online Documentation for DB Comparer for MySQL

Compare options

Set specific parameters of comparison for each type of database objects.



Select an object type in the object tree, set a flag to include the object type into the comparison process and define Compare properties in the corresponding group within the Compare Options tab.


The Script generation group allows you to specify whether a specific type of script (CREATE, ALTER, DROP) should be generated for objects of the selected type.


The Select All, Unselect All and Invert Selection buttons are implemented to make options selection easier.
