PL/SQL How to call a function without getting returned object
declaration, function, oracle, plsql, return-value
Solution
Very simple: create a procedure which covers this function
PROCEDURE do_something
IS
dummy boolean;
BEGIN
dummy := do_something();
END;
Sorry, but this is the only way in PL/SQL. This language is very strict in definitions of procedure and function and you cannot make a function call without handling the result. But you can make a procedure as it is shown in example above.
It will define automatically where to choose the function and where the procedure.
EDIT
As far as there are people who do not trust me (sometimes I really tell bad things so doubts are allowed :) ) this is the test:
declare
myresult boolean;
function do_something return boolean
is
begin
return true;
end;
procedure do_something
is
dummy boolean;
begin
dummy := do_something();
end;
begin
myresult := do_something();
do_something();
end;
works well.
Problem
I have a function in PL/SQL: ``` FUNCTION do_something RETURN BOOLEAN IS ... BEGIN ... END ``` This function can be called as such: ``` DECLARE answer BOOLEAN; BEGIN answer := do_something(); END ``` Now, there are cases, where I don't need the returned boolean. If I don't want to get it and just write: ``` do_something(); ``` I get PLS-00306 (wrong number of types of arguments in call to DO_SOMETHING) Is there a way to call it without declaring and setting a new boolean, which I will never use in this case?
