How to substitute bind variable in pl/sql developer tool

问题

I would like to run a SQL script in PL/SQL developer as following example.

variable vTest varchar2;
(exec/set) :vTest := 'ABC'
select :vTest from dual;
select :vTest ||'XYZ' from dual ;
select * from table  where columnname = :vTest;

You can do this in a Test Window.

First do a

grant debug connect session to <schema> 

Then open a new Test window. Declare your bind variables at the bottom of the screen. You give them a name, a type and a value there.
