When executing a query, there are extra spaces at the end of the field which are remaining when exporting to .csv file. These spaces do not occur in the database table istelf. e.g.
select 'TEST' from dual will show as 'TEST ' in the data grid.
Issue only occurs when the following option is selected:
View | Toad Options | Oracle | General | 'Newline format for character data' | 'Unix Style'
WORKAROUND
Set View | Toad Options | Oracle | General | 'Newline format for character data' to 'Windows style'
STATUS
Waiting for fix in a future release of Toad for Oracle
