ORA-14551：使用Execute immediate时，无法在查询错误内执行DML操作

Question

CREATE OR REPLACE FUNCTION XXCHR_UPDATE      (
                                                                P_SALESREP_ID          IN   NUMBER,
                                                                p_COLUMN_NAME           IN     VARCHAR2,
                                                                P_COLUMN_VALUE            IN   varchar2
                                                           )
   RETURN VARCHAR2

IS

   lv_dyn_sql                        VARCHAR2(2000):= NULL;

BEGIN


        lv_dyn_sql := 'UPDATE thirty_days
                SET attribute86 ='||p_COLUMN_NAME||',attribute87 ='||P_COLUMN_VALUE
                || 'WHERE SALESREP_ID = :1';     

    EXECUTE IMMEDIATE lv_dyn_sql using P_SALESREP_ID;

    return(1);



EXCEPTION
      WHEN OTHERS
      THEN
         dbms_output.put_line('Returning Error : '||SQLERRM);
         --lv_return_val:= 0;
     RETURN SQLERRM;

END XXCHR_UPDATE;

当我执行此函数时，返回错误

  

ORA-14551

请在这里建议

Answer 1

尝试修改你的陈述：

lv_dyn_sql := 'UPDATE thirty_days
                SET attribute86 ='||p_COLUMN_NAME||',attribute87 ='||P_COLUMN_VALUE
                || 'WHERE SALESREP_ID = :1';

到

lv_dyn_sql := 'UPDATE thirty_days
                SET attribute86 ='||p_COLUMN_NAME||',attribute87 ='||P_COLUMN_VALUE
                || 'WHERE SALESREP_ID ='||P_SALESREP_ID;  

当然：

EXECUTE IMMEDIATE lv_dyn_sql;

Answer 2

为什么不是所有三个参数？摆脱字符串连接：

lv_dyn_sql := q'[UPDATE thirty_days
                    SET attribute86 = :arg1
                      , attribute87 = :arg2
                  WHERE SALESREP_ID = :arg3]';

execute immediate lv_dy_sql using p_column_name, p_column_value, p_salesrepid;
