摘要:之前在项目中解决了插入字符串类型的数据,今天试着写了一个插入date类型的字段,成功了,现在记录一下,以便以后查看:

一:首先建立一个根据xml节点名称获取对应的xml值的Function.sql:

二:其次建立一个格式化字符串时间的Funcation.sql:

CREATE OR REPLACE FUNCTION MIP.FormatDateValue (key VARCHAR2, value VARCHAR2)
   RETURN VARCHAR2
IS
   --定义几个变量,出来解析过来的时间字符串
   --日月年时分(11OCT141024)
   AA       VARCHAR2(32);

   DAY      VARCHAR2(100);

   MOUNTH   VARCHAR2(100);

   YEAR     VARCHAR2(100);

   HOUR     VARCHAR2(100);

   MINUTE   VARCHAR2(100);

   ValueReturn   VARCHAR2 (100);

BEGIN

   IF key = ' ' THEN

   ValueReturn := ' ';

   RETURN ValueReturn;

   ELSE

   DAY := SUBSTR(key,0,2);
   
   MOUNTH := SUBSTR(key,3,3);
   
   IF INSTR (MOUNTH,'JAN') > 0 THEN
   MOUNTH := 01;
   END IF;
   
   IF INSTR (MOUNTH,'FEB') > 0 THEN
   MOUNTH := 02;
   END IF;
   
   IF INSTR (MOUNTH,'MAR') > 0 THEN
   MOUNTH := 03;
   END IF;
   
   IF INSTR (MOUNTH,'APR') > 0 THEN
   MOUNTH := 04;
   END IF;
   
   IF INSTR (MOUNTH,'MAY') > 0 THEN
   MOUNTH := 05;
   END IF;
   
   IF INSTR (MOUNTH,'JUN') > 0 THEN
   MOUNTH := 06;
   END IF;
   
   IF INSTR (MOUNTH,'JUL') > 0 THEN
   MOUNTH := 07;
   END IF;
   
   IF INSTR (MOUNTH,'AUG') > 0 THEN
   MOUNTH := 08;
   END IF;
   
   IF INSTR (MOUNTH,'SEP') > 0 THEN
   MOUNTH := 09;
   END IF;
   
   IF INSTR (MOUNTH,'OCT') > 0 THEN
   MOUNTH := 10;
   END IF;
   
   IF INSTR (MOUNTH,'NOV') > 0 THEN
   MOUNTH := 11;
   END IF;
   
   IF INSTR (MOUNTH,'DEC') > 0 THEN
   MOUNTH := 12;
   END IF;
   
   YEAR := SUBSTR(key,6,2);
   
   HOUR := SUBSTR(key,8,2);
   
   MINUTE := SUBSTR(key,-2);
   
   AA := 20;

   --日月年时分(11OCT141017)
   ValueReturn := AA || YEAR || '-' || MOUNTH || '-' || DAY || ' ' || HOUR || ':' || MINUTE;
   
   --ValueReturn := HOUR || ':' || MINUTE;

   RETURN ValueReturn;

   END IF;

END FormatDateValue;

三:建立插入数据表的存储过程.sql:

CREATE OR REPLACE PROCEDURE MIP.PRO_TEST (xmlStr IN CLOB)
IS
   TIME    VARCHAR2(100);
   
   TIME_F  VARCHAR2(100);

BEGIN

   --TIME := GetXmlNodeValue (xmlStr, 'TIME');
   
   TIME_F := FORMATDATEVALUE (GetXmlNodeValue (xmlStr, 'TIME'), 'TIME_F');
   
   INSERT INTO TEST (ID,TIME) VALUES (TEST_SEQ.NEXTVAL,to_date(TIME_F,'yyyy-mm-dd hh24:mi:ss'));
   
   COMMIT;

EXCEPTION

   WHEN OTHERS

   THEN

      DBMS_OUTPUT.PUT_LINE (SQLERRM);

END PRO_TEST;
/

登录后复制

四:建立行级触发器.sql:

DROP TRIGGER MIP.COPY_TEST_TRIGGER;

CREATE OR REPLACE TRIGGER MIP.COPY_TEST_TRIGGER
   AFTER INSERT
   ON MIP.MBINMSGS    FOR EACH ROW
DECLARE
-- LOCAL VARIABLES HERE
BEGIN
   PRO_TEST (:NEW.MBINMSGS_CLOB_MSG);
END COPY_TEST_TRIGGER;
/

登录后复制
五:给其中的原始数据表插入一条数据,查看是否解析成功并插入到对应的表中:

Insert into MBINMSGS
   (ID, MBINMSGS_CLOB_MSG, MBINMSGS_DATE_RECEIVED, MBINMSGS_DATE_PROCESSED, MBINMSGS_SUBSYSTEM_NAME, 
    MBINMSGS_SUBSYSTEM_DATE_SENT, SERVICENAME)
 Values
   (1931300, '


      DC    20141010230216    FLOP    FGIS        CA-CA1895-D-11OCT141730-D    11OCT141730      
', TO_DATE('10/20/2014 11:20:42', 'MM/DD/YYYY HH24:MI:SS'), TO_DATE('10/20/2014 17:23:40', 'MM/DD/YYYY HH24:MI:SS'), 'DC2', 
    TO_DATE('10/20/2014 11:28:05', 'MM/DD/YYYY HH24:MI:SS'), 'DC2GIS');
    COMMIT;

六:查看对应的数据表中时间类型的字段是否有值:
