Excuse me, I’m new to the group, it may not be the right group.
In toad I have the possibility of making a double query in different tables and being able to visualize the results in the same window?
yes you can do this. Just choose the 'Run as a Script' option. This will open individual grid tabs on the output screen and you can see the results for each query.
If you want to see both grids at the same time: highlight the first table name and press to open the data in a describe window and then highlight the second statement and press to run the statement. The describe window can be moved to any position in all versions of TOAD.
