Hi David,
If you want to fetch more than 1,000 rows you have to go to Toad Options.
For this go to Tools Menu->Options.
Locate Database Folder->General
There is a parameter called "Number of rows to initially fetch in data tab". Modify this to your convenience. be careful and take into consideration this could affect visualization performance and network traffic. You can check the "Unlimited" option and then you will bu using database parameter.
If you are connecting to an Oracle Database there is a specific parameter for this under the "Oracle" Database parameter.
Hope this could help you!
Regards,
Ronaldo.
