In the DB2 Admin Client (8.2.4), when the results of a query are displayed
in the grid that looks like a spreadsheet (using Command Editor or double
click on table name in Control Center). The data in this grid is updatable.

When a cursor is first placed on one of the columns, no update takes place.
When the cursor is then merely moved to another row (any column) the
previous row is updated, even if it was not changed. If the user does not
have authority to update the table, then a sqlcode -551 is displayed
indicating that they are authorized to update the table.

Is there any way let users query the data using these tools, and let them
move the cursor around without updating the data? This seems like a very
questionable design. There should be some way to let users just query the
data with tool without attempting updates just because they place the cursor
on a row in the grid.
