Remarks

The MsiDatabaseOpenView function opens a view object for a database. You must open a view object for a database before performing any execution or fetching.

If an error occurs, you can call MsiGetLastErrorRecord for more information.

Note that it is recommended to use variables of type PMSIHANDLE because the installer closes PMSIHANDLE objects as they go out of scope, whereas you must close MSIHANDLE objects by calling MsiCloseHandle. For more information see Use PMSIHANDLE instead of HANDLE section in the Windows Installer Best Practices.

If the function fails, you can obtain extended error information by using MsiGetLastErrorRecord.
