Question

How do I call an Oracle stored procedure with parameters?

It has one input and one output parameter, and looks like doSomething(IN x,OUT y);.

How do I call it from the command line?

Answer 1

Assuming SQL*Plus:

var v_result number
exec doSomething(42, :v_result);
print v_result

You can put that into a SQL script and pass that on the commandline to SQL*Plus.
