[ApplySQL] not allowed for userPrivileged [ApplySQL] not allowed for user

Hi, I am designing a small Windows Forms application, which will allow users to add/delete/view an item to/from Innovator database directly. From this application I can add Document and its attachment, now I want to open that document, and for that I write a sql query, but I get an error like this: [ApplySQL] not allowed for userPrivileged [ApplySQL] not allowed for user    Regards, Maddy.
