oracle基础知识积累-oracle的for循环使用

场景:
    基础知识查询
动机:
    纯粹基础知识积累,便于后续查询.在很多场合,负责人们都在谈论去IOE话题,
所以,难免使用场合会或多或少会减少,于是按照习惯的思路记录一下.
环境: 
    Oracle Database 11g; PL/SQL Developer
1.for循环取出游标数据

CREATE OR REPLACE PROCEDURE PRO_TEST_CURSOR_FOR(ERRORMSG OUT VARCHAR2) IS BEGIN   DECLARE     --定义游标     CURSOR LOG_INFO_CUR IS       SELECT * FROM F_LOG_INFO;   BEGIN     ERRORMSG := '';     --取出一行数据     FOR F_LOG_INFO_ROW IN LOG_INFO_CUR LOOP        INSERT INTO F_LOG_INFO_TEMP         (TASK_ID,          BEGIN_TIME,          END_TIME,          FLAG,          FAIL_INFO,          DATA_COUNT,          TABLE_NAME)       VALUES         (F_LOG_INFO_ROW.TASK_ID,          F_LOG_INFO_ROW.BEGIN_TIME,          F_LOG_INFO_ROW.END_TIME,          F_LOG_INFO_ROW.FLAG,          F_LOG_INFO_ROW.FAIL_INFO,          F_LOG_INFO_ROW.DATA_COUNT,          F_LOG_INFO_ROW.TABLE_NAME);       COMMIT;     END LOOP;     END; EXCEPTION   WHEN OTHERS THEN     ERRORMSG := 'PRO_TEST_CURSOR_FOR抛出异常: ' || SQLERRM; END PRO_TEST_CURSOR_FOR;

2.for循环取出数值

CREATE OR REPLACE PROCEDURE PRO_TEST_CURSOR_FOR2(ERRORMSG OUT VARCHAR2) IS BEGIN   BEGIN     ERRORMSG := '';     --取出一行数据     FOR V_TASK_ID IN 1 .. 100 LOOP       INSERT INTO F_LOG_INFO_TEMP         (TASK_ID,          BEGIN_TIME,          END_TIME,          FLAG,          FAIL_INFO,          DATA_COUNT,          TABLE_NAME)       VALUES         (V_TASK_ID,          SYSDATE,          SYSDATE,          'FLAG',          'FAIL_INFO',          100,          'TABLE_NAME');       COMMIT;     END LOOP;   END; EXCEPTION   WHEN OTHERS THEN     ERRORMSG := 'PRO_TEST_CURSOR_FOR抛出异常: ' || SQLERRM; END PRO_TEST_CURSOR_FOR2;

2.附本例使用表一

create table F_LOG_INFO (   task_id    NUMBER(16) not null,   begin_time DATE,   end_time   DATE,   flag       VARCHAR2(8),   fail_info  VARCHAR2(512),   data_count NUMBER(16),   table_name VARCHAR2(256) ); alter table F_LOG_INFO   add constraint PK_F_LOG_INFO primary key (TASK_ID);

3.附本例使用表二

create table F_LOG_INFO_TEMP (   task_id    NUMBER(16) not null,   begin_time DATE,   end_time   DATE,   flag       VARCHAR2(8),   fail_info  VARCHAR2(512),   data_count NUMBER(16),   table_name VARCHAR2(256) ); alter table F_LOG_INFO_TEMP   add constraint PK_F_LOG_INFO_TEMP primary key (TASK_ID);   

以上,感谢.
