Simple Oracle Procedure Failing - oracle

Question

I have a very simple test proc:
create or replace PROCEDURE TestSproc
(userName in VARCHAR2, p_Test OUT SYS_REFCURSOR)IS
BEGIN
OPEN p_Test FOR
SELECT * FROM Test_Table
WHERE name = userName ;
END TestSproc;
When I run the proc (ctrl f10) in sqldeveloper on the proc page I get the result I would expect. But when I try to call the proc with the below query I get the error:
Error starting at line : 1 in command - begin DB.TestSproc('Phil'); end;
Error report - ORA-06550: line 2, column 1:
PLS-00306: wrong number or types of arguments in call to 'TestSproc'
ORA-06550: line 2, column 1: PL/SQL: Statement ignored
06550. 00000 - "line %s, column %s:\n%s"
*Cause: Usually a PL/SQL compilation error.
*Action:
begin
DB.TestSproc('Phil');
end;
Can anyone please point me in the correct direction.
EDIT
In SQL Server I would simply do:
USE DB;
GO
EXEC dbo.TestSproc#Name= 'Phil';

Answer 1

Assuming you are using Oracle 12c with a 12c client:
create or replace procedure testsproc
( username in varchar2 )
as
resultset sys_refcursor;
begin
open resultset for
select * from test_table
where name = username;
dbms_sql.return_result(resultset);
end testsproc;
Then call it with
exec testsproc('Phil')
or
call testsproc('Phil');
or
begin
testsproc('Phil');
end;
depending on what you are calling it from.

You have to put the output somewhere, so - declare an appropriate variable:
SQL> create or replace procedure p_test (par_deptno in number, p_emps out sys_refcursor) is
2 begin
3 open p_emps for
4 select deptno, empno, ename
5 from emp
6 where deptno = par_deptno;
7 end;
8 /
Procedure created.
SQL>
SQL> var l_out refcursor
SQL>
SQL> begin
2 p_test(10, :l_out);
3 end;
4 /
PL/SQL procedure successfully completed.
SQL>
SQL> print :l_out;
DEPTNO EMPNO ENAME
