Database that does not include the changes

Return Value
Boolean
true if a transform is generated, or false if a transform is not generated because there are no differences between the two databases.
Remarks

A transform can add non-primary key columns to the end of a table. A transform cannot be created that adds primary key columns to a table. A transform cannot be created that changes the order, names, or definitions of columns.

If the transform is to be applied during an installation you must use the CreateTransformSummaryInfo(Database, String, TransformErrors, TransformValidations) method to populate the summary information stream.
