Execute a stored function from command line

Question

Hello,
I have a db stored function and I need to execute it from command line. I've tried by this way:
(I need to connect with sys credentials)
sqlplus sys/mypwd@mydb AS SYSDBA @myfile.sql
and myfile.sql is:
exec myschema.sf_test;
but I get this error:
ERROR at line 1:
ORA-06550: line 1, column 7:
PLS-00221: 'sf_test' is not a procedure or is undefined
ORA-06550: line 1, column 7:
PL/SQL: Statement ignored

Answer 1

You can use exec command for the execution of a procedure with out bind variable, but for a function always use bind variable.
Function should return a value, so you must have to assign the function return value to a variable.
like given below(or simply query the function using select statement)
Method 1
======
variable v1 number;
exec :v1 := t_func;
Method 2
======
declare
x1 NUMBER;
begin
x1 := t_func;
end;
SQL> create function t_func return number
2 as
3 begin
4 return 0;
5 end;
6 /
Function created.
SQL> exec t_func;
BEGIN t_func; END;
ERROR at line 1:
ORA-06550: line 1, column 7:
PLS-00221: 'T_FUNC' is not a procedure or is undefined
ORA-06550: line 1, column 7:
PL/SQL: Statement ignored
Method 3
======
SQL> select t_func from dual;
T_FUNC
0
