How to execute an oracle stored procedure?
Both 'is' and 'as' are valid syntax. Output is disabled by default. Try a procedure that also enables output...
create or replace procedure temp_proc isbegin DBMS_OUTPUT.ENABLE(1000000); DBMS_OUTPUT.PUT_LINE('Test');end;
...and call it in a PLSQL block...
begin temp_proc;end;
...as SQL is non-procedural.
