Query results in the data grid that contains a LONG datatype field will display 'Excluded' rather than the actual data.
(See document: grid.bmp)
The default in Toad for Data Analysis was changed to NOT read LONG datatypes to increase performance.
Manually fetch the data:
1. Click in one of the cells that has the (Excluded) entry.
2. A pop-up a dialog will ask:
To fetch this data, Toad must re-execute the entire query, Do you want to continue?
3. Select OK.
Change the default behavior in the options menu:
1. Go to Tools | Options | Database | General in the main menu.
2. Check the "Read LOBs when initially fetching data" check box.
3. Click on Apply and OK.
