This is not a 'software' feature, however, I have contacted Quest when a version had a very specific bug that was affecting my team. This is a great timesaver as I do not have to type in all of the escape/concatenation characters just to create a SQL statement in C# or C++. I can easily export a complex SQL statement to a programming language. The PL/SQL debugger is fantastic and has been a huge time-saver.Ī quite simple feature that I have not encountered elsewhere is the 'Make Code' feature. TOAD is one of only a few applications that I have not had to complement with additional software or 'add-ons'. First, Toad 9 should be assumed to only work with the Oracle version that was current at the time of Toad 9 release which is 10g.The most valuable feature is honestly that so many features are packed into a single software package. Toad might work with newer databases, but language syntax and data dictionary changes will cause problems for sure.

Second, if you're trying to use that 12c client shown in your path you're out of luck. You should be using a 10g client although an 11g client should be OK here too. Third, Toad does not require TNS_ADMIN environment variable, but it's nice to use one especially if you have multiple clients installed and want to share your. When you set your TNS_ADMIN variable did you set it at the system level too? Your screenshot shows a SET TNS_ADMIN command at a command prompt. That setting is valid only for the duration of that command prompt. Once you close that session its value is lost. Set TNS_ADMIN using the Environment Variables dialog in Windows. My Toad 9 installation is only capable of seeing/using one of my 3 installed clients. It cannot locate my 11g or 12c instant clients. Toad 9 is very old and should not be expected to function with newer Oracle software. In addition, bugs related to client detection and establishing connections have been fixed over the years.
