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.
