Compare schemas

Supported (optional) by a growing number of customized database vendor specific modules SQL offeres the possibily to compare schemas.

Choose your two schemas in order to compare to

Choose both datamodels and start in menu Datamodel->Compare Schemas....
Hint: Both schemas will complete loading of all objects. In most cases one connection has not enough permissions to load metadata for both schemas.
It can be neccessary to start a differenz connection (by opening a new window and connect to an other database) to have full read access to both schemas.
In this case you find the second schema under a new connection node in the datamodel view.
