Description | Use the revDatabaseType function to send different queries or
perform different operations depending on what kind of database is being
used.
You can use the revDatabaseType function to distinguish between
different database types. For example, you may need to frame a
SQL query differently depending on what type of database you are
communicating with.
Important: The revDatabaseType function is part of the
Database library. To ensure that the function works in a
standalone application, you must include this
custom library when you create your
standalone. In the Inclusions pane of the
Standalone Application Settings window, make sure both the
"Database" library checkbox and those of the database drivers you are
using are checked.
