    <p>I'm getting SQL_INVALID_HANDLE error when calling SQLColAttribute from an application (trying to communicate with self developed odbc driver) I don't know why the handle is stated an invalid handle, since its a simple struct, which is still valid at runtime, ive checked it.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
