I'm used to Toad, where just by clicking F9 it would automatically prompt me to type my input parameters for any query.
However, in SQLDeveloper I am only prompted to input them once, & then every time I use F9 the tool uses the inital parameters, forcing me to close & reopen a script if I want to change the parameter.
Do you know of any command to prevent this?
I wasn't able to resolve it permanently, but I found a work-around. Probably it's even the correct approach.
In order to reuse a variable in a query, particularly in SQL Developer, use "UNDEFINE":
UNDEFINE [variable_name];
