程序不运行

Question

我正在运行ning 下面查询，给出错误。需要做什么才能获得请求的结果？

create or replace PROCEDURE data_cleanup_29th_nov_2020
IS
BEGIN

EXECUTE IMMEDIATE 'create table TEMP_ID_STAT_TIME_FRM_JOB_DOC as select JOB_ID, last_update_time_utc, status from J_DOC where 
LAST_UPDATE_TIME_UTC <= TRUNC(SYSDATE) - 30 and status=''Sent''';

  execute immediate 'delete from HUB_SIG where JOB_id IN ( SELECT JOB_ID
  FROM TEMP_ID_STAT_TIME_FRM_JOB_DOC)';

 execute immediate 'delete from J_DOC 
 where JOB_id IN ( SELECT JOB_ID
  FROM TEMP_ID_STAT_TIME_FRM_JOB_DOC)';

EXECUTE IMMEDIATE 'RENAME TABLE TEMP_ID_STAT_TIME_FRM_JOB_DOC TO TEMP_JOB_ID_FROM_JOB_DOC_1119';

END;

commit;

在运行ning 程序出现以下错误后

BEGIN
  data_cleanup_29th_nov_2020();
--rollback; 
END;

ORA-00955: name is already used by an existing object ORA-06512: at "HUB.DATA_CLEANUP_29TH_NOV_2020", line 7 ORA-06512: at line 2 00955. 00000 - "name is already used by an existing object

尝试了以下查询：

CREATE OR REPLACE PROCEDURE ATAS_CLEANUP_NOV_2020 IS
BEGIN
    EXECUTE IMMEDIATE 'create table TEMP_ID_STAT_TIME_FRM_JOB_DOC as select JOB_ID, last_update_time_utc, status from J_DOC where 
LAST_UPDATE_TIME_UTC <= TRUNC(SYSDATE) - 30 and status=''Sent''';

    EXECUTE IMMEDIATE 'delete from HUB_SIGNATURE_DETAILS where JOB_id IN ( SELECT JOB_ID
  FROM TEMP_ID_STAT_TIME_FRM_JOB_DOC)';

    EXECUTE IMMEDIATE 'delete from J_DOC
 where JOB_id IN ( SELECT JOB_ID
  FROM TEMP_ID_STAT_TIME_FRM_JOB_DOC)';

    --EXECUTE IMMEDIATE 'RENAME TABLE TEMP_ID_STAT_TIME_FRM_JOB_DOC TO TEMP_JOB_ID_FROM_JOB_DOC_1119';
    BEGIN
        EXECUTE IMMEDIATE 'DROP TABLE TEMP_JOB_ID_FROM_JOB_DOC_1119';
    EXCEPTION
        WHEN OTHER THEN
            NULL;
    END;
    EXECUTE IMMEDIATE 'ALTER TABLE TEMP_ID_STAT_TIME_FRM_JOB_DOC RENAME TO TEMP_JOB_ID_FROM_JOB_DOC_1119';
END;

出现以下错误：

Error(14,5): PL/SQL: Statement ignored Error(17,14): PLS-00201: identifier 'OTHER' must be declared

试过这个并且成功：

CREATE OR REPLACE PROCEDURE ATAS_LATEST_DATA_cleanup_nov IS
BEGIN


    EXECUTE IMMEDIATE 'delete from HUB_SIG where JOB_id IN ( SELECT JOB_ID
  FROM TEMP_ID_STAT_TIME_FRM_JOB_DOC)';

    EXECUTE IMMEDIATE 'delete from J_DOC 
 where JOB_id IN ( SELECT JOB_ID
  FROM TEMP_ID_STAT_TIME_FRM_JOB_DOC)';

    --EXECUTE IMMEDIATE 'RENAME TABLE TEMP_ID_STAT_TIME_FRM_JOB_DOC TO TEMP_JOB_ID_FROM_JOB_DOC_1119';
   --BEGIN
     -- EXECUTE IMMEDIATE 'DROP TABLE TEMP_JOB_ID_FROM_JOB_DOC_1119';
    --EXCEPTION
      --  WHEN OTHER THEN
        --   NULL;
   -- END;
    EXECUTE IMMEDIATE 'ALTER TABLE TEMP_ID_STAT_TIME_FRM_JOB_DOC RENAME TO TEMP_JOB_ID_FROM_JOB_DOC_1119';
END;

COMMIT;

BEGIN
  ATAS_LATEST_DATA_cleanup_nov();
--rollback; 
END;

匿名区块完成

在过程外创建临时 table。 create table TEMP_JOB_ID_FROM_JOB_DOC_1119 as select JOB_ID, last_update_time_utc, status from J_DOC where LAST_UPDATE_TIME_UTC <= TRUNC(SYSDATE) - 30 和状态='Sent'

并且在运行数据出现在 TEMP_JOB_ID_FROM_JOB_DOC_1119

之后，现在使用临时 table 内部程序

现在我们必须实现获取日期作为输入并传递它当重命名 table (RENAME TEMP_ID_STAT_TIME_FRM_JOB_DOC TO TEMP_JOB_ID_FROM_JOB_DOC_1119 )

并在 DBMS_SCHEDULER 到运行每晚太平洋标准时间晚上 10 点安排此程序。我们该怎么做？

Answer 1

请检查“create table TEMP_ID_STAT_TIME_FRM_JOB_DOC”这个 create table 语句，因为“TEMP_ID_STAT_TIME_FRM_JOB_DOC”已经存在于您的系统中。

Answer 2

你的rename table命令有误。

应该是：

ALTER TABLE TEMP_ID_STAT_TIME_FRM_JOB_DOC RENAME TO TEMP_JOB_ID_FROM_JOB_DOC_1119;

此外，您可以执行该过程一次，如果您要再次执行它，那么它会在重命名命令中抛出错误。

现在，查看数据库中是否已有 table 可用。如果是，则在再次调用以下过程之前将其删除。

所以试试这个代码：

CREATE OR REPLACE PROCEDURE DATA_CLEANUP_29TH_NOV_2020
(P_IN_DATE IN DATE)
IS
BEGIN
    EXECUTE IMMEDIATE 'create table TEMP_ID_STAT_TIME_FRM_JOB_DOC as select JOB_ID, last_update_time_utc, status from J_DOC where 
LAST_UPDATE_TIME_UTC <= TRUNC(SYSDATE) - 30 and status=''Sent''';

    EXECUTE IMMEDIATE 'delete from HUB_SIG where JOB_id IN ( SELECT JOB_ID
  FROM TEMP_ID_STAT_TIME_FRM_JOB_DOC)';

    EXECUTE IMMEDIATE 'delete from J_DOC 
 where JOB_id IN ( SELECT JOB_ID
  FROM TEMP_ID_STAT_TIME_FRM_JOB_DOC)';

    --EXECUTE IMMEDIATE 'RENAME TABLE TEMP_ID_STAT_TIME_FRM_JOB_DOC TO TEMP_JOB_ID_FROM_JOB_DOC_1119';
    BEGIN
        EXECUTE IMMEDIATE 'DROP TABLE TEMP_JOB_ID_FROM_JOB_DOC_1119';
    EXCEPTION
        WHEN OTHER THEN
            NULL;
    END;
    EXECUTE IMMEDIATE 'ALTER TABLE TEMP_ID_STAT_TIME_FRM_JOB_DOC RENAME TO TEMP_JOB_ID_FROM_JOB_DOC_' || TO_CHAR(P_IN_DATE, 'MMYY');
END;
/

避免动态查询总是好的做法。

您可以在此过程之外创建一个 table 并用它来存储临时数据。或者您可以使用全局临时 table.
