I’m using 12.1
I have the unfortunate inconvenience of having to work with MiXed CaSE column names for some data conversion tables I’m dealing with. With that said Toad does a great job at double quoting columns when needed but I found an instance where that is missing. in the SB (describe window too) on the tables tab. If you are on the data grid, select a cell then click on the filter drop down button and select ‘Add to filter “MixedCaseColumn” = current value’ it pops up the filter dialog but the column is not double quoted. It shows up correctly in the drop down menu as being double quoted though.
