Invalid identifier quoted string not properly identified.
Toad 13.1 will throw the following error: "ORA-00904: "SRC"."TYPE_:" invalid identifier". This SQL completes as expected when run in Toad v12.11, if the exact same steps are followed.
For some reason, it appears that it's not reading in the "code" portion of the "src.type_code" identifier, the last bit of text at the very end of the SQL code.
If the SQL is selected/highlighted and the shortcut is used, then the script will execute successfully. The SQL will also execute correctly if either the "Execute/compile as statement at caret" or "Execute as script" buttons are used.
