Ausführen einer dynamischen SQL-Abfrage in Oracle

Die Dynamik String muss in 'Single Quotes' eingeschlossen werden

OPEN OUT_CUR FOR
     'SELECT * FROM MYTABLE WHERE ID '|| DYN_QUERY;

EXECUTE IMMEDIATE erlaubt mehrzeiliges Ergebnis, wenn Sie BULK COLLECT verwenden

Beispiel:

DECLARE
  TYPE myarray IS TABLE OF VARCHAR2(100);
  v_array myarray;
BEGIN
  EXECUTE IMMEDIATE 'select ''x'' from dual union all select ''y'' from dual'
    BULK COLLECT INTO v_array;

  --Or you could use the alternative quoting mechanism to avoid doubling quotation marks.
  --EXECUTE IMMEDIATE q'[select 'x' from dual union all select 'y' from dual]'
  --  BULK COLLECT INTO v_array;

  FOR i IN 1..v_array.count
  LOOP
    DBMS_OUTPUT.PUT_LINE(v_array(i));
  END LOOP;
END;

EXECUTE IMMEDIATE mit bind-Variablen;

String := 'SELECT * FROM EMP WHERE name = :name AND age = :age AND :name <> ''Mahesh''';

EXECUTE IMMEDIATE String USING 'Mahi',21,'Mahi';
<OR>
EXECUTE IMMEDIATE String USING proc_variable1,proc_variable2,proc_variable1;
