立即执行缺少右括号错误

Question

我的程序中有如下代码。当我调用该过程时，出现缺少右括号错误。当我在程序外测试它时，没有立即执行子句，它工作正常。 谁能帮我消除错误？

EXECUTE IMMEDIATE '
  INSERT INTO prehledcen
    (id_obchodu
    ,id_obchodu_poradi
    ,smer
    ,typceny
    ,vzdalenost
    ,hodnotaceny
    ,kid)
    SELECT a.id_obchodu
          ,a.id_obchodu_poradi
          ,smer
          ,''PredchoziLast''
          ,predchozi_last_time - datum_obchodu
          ,predchozi_last
          ,kid
        FROM middle_office.f_d_obchody_zmeny_test a
   INNER JOIN (SELECT id_obchodu
                     ,id_obchodu_poradi
                     ,MAX(dwh_insert_process) dwh_insert_process
                     ,MIN(insert_sysdate) insert_sysdate
                 FROM middle_office.f_d_obchody_zmeny_test b
                GROUP BY id_obchodu
                        ,id_obchodu_poradi) b
      ON b.id_obchodu = a.id_obchodu
     AND b.id_obchodu_poradi = a.id_obchodu_poradi
     AND a.dwh_insert_process = b.dwh_insert_process
   WHERE (datum_obchodu >= ' || v_datum_od || ' OR
         (datum_obchodu < ' || v_datum_od || ' AND  b.insert_sysdate >= ' || v_datum_od || '))';

Answer 1

我假设您 v_datum_od 的值不正确。试试这个：

EXECUTE IMMEDIATE '
  INSERT INTO prehledcen
  ...
   WHERE (datum_obchodu >= :d1 OR (datum_obchodu < :d2 AND b.insert_sysdate >= :d3))' 
USING v_datum_od, v_datum_od, v_datum_od;
