Fel vid utskrift av REFCURSOR-variabel som OUT-parameter i proceduren i Oracle 11g

var r ref cursor;

Ovanstående är syntaktisk felaktigt. Det borde vara -

var r refcursor

Det finns inget mellanrum mellan ref-markören, det är ett ord, refcursor .

Till exempel,

SQL> create table t as select * from emp;

Table created.

SQL> var r refcursor
SQL>
SQL> begin
  2     open :r for select * from t;
  3  end;
  4  /

PL/SQL procedure successfully completed.

SQL>
SQL> delete from t;

14 rows deleted.

SQL> commit;

Commit complete.

SQL>
SQL> print r
