Select one or more of the databases for which you intend to generate schema. Typical properties belonging to a database set are SQL Data Type, SQL Type Qualifier, Nullity, Constraint Name, and SQL Trigger.
There are several ways to select databases in the Target Database field:
To select a single database
Click the desired database name.
To select a contiguous set of databases
Either:
Click the first desired database without releasing the button, and then move your mouse downwards to the last database you want to select; or
Press Shift and click, then move upwards or downwards until the highlighted selection contains the databases you want to select.
