Select * from &MySchema..&My_tables_list_iterator;
Toad For Oracle 12.10.0.30
I have the same issue and no resolution after 2 hours of searches and trial and error.
The Set Variables dialog in the Export Dataset action does not show List Iterator variables in the Environment Variables list.
The &MySchema in my query is a global toad variable, so that works fine. But the table names that I want to loop over should come from the parent List Iterator, but that iterator variable is not recognized at all.
