I just upgraded to TDA v2.7. In the previous version, if I selected a table in the Object Explorer and then looked at its Index tab on the right hand side, there was a bar there that had Create Index, Drop Index, etc. on it. In v2.7 this bar and those buttons are gone. In v3.0 the bar is there, but there is only a Defrag Index button. I have looked all over and I cannot find a Create Index button or option when viewing a table. Is there still one?
For Oracle, you can right click on the table and select Create Index. For other database types, there is not a workaround.
Waiting for fix to be released in a future versio of Toad for Data Analysts.
