摘要：之前在項目中解決了插入字符串類型的數據，今天試著寫了一個插入date類型的字段，成功了，現在記錄一下，以便以后查看：

一：首先建立一個根據xml節點名稱獲取對應的xml值的Function.sql:

CREATE OR REPLACE FUNCTION MIP.GetXmlNodeValue (xmlStr CLOB, nodeName VARCHAR2)RETURN VARCHAR2
IS--創建xml解析器實例xmlparser.ParserxmlPar        xmlparser.Parser := xmlparser.newParser;--定義DOM文檔xDoc          xmldom.DOMDocument;--定義item子節點數目變量lenItme       INTEGER;--定義節點列表，存放item節點們itemNodes     xmldom.DOMNodeList;--定義節點，存放單個item節點itemNode      xmldom.DOMNode;ValueReturn   VARCHAR2 (100);BEGIN--解析xmlStr中xml字符串，并存放到xmlPar中xmlparser.parseClob (xmlPar, xmlStr);--將xmlPar中的數據轉存到dom文檔中xDoc := xmlparser.getDocument (xmlPar);--釋放解析器實例xmlparser.freeParser (xmlPar);--獲取所有item節點itemNodes := xmldom.getElementsByTagName (xDoc, nodeName);--獲取item節點的個數lenItme := xmldom.getLength (itemNodes);--如果無該標簽，則返回EMPTYIF lenItme = 0 THENValueReturn := ' ';ELSE--獲取節點列表中的第1個item節點itemNode := xmldom.item (itemNodes, 0);--獲取所有子節點的值ValueReturn := xmldom.getNodeValue (xmldom.getFirstChild (itemNode));END IF;   --釋放domxmldom.freeDocument(xDoc);RETURN ValueReturn;END GetXmlNodeValue;
/

二：其次建立一個格式化字符串時間的Funcation.sql:

CREATE OR REPLACE FUNCTION MIP.FormatDateValue (key VARCHAR2, value VARCHAR2)RETURN VARCHAR2
IS--定義幾個變量，出來解析過來的時間字符串--日月年時分(11OCT141024)AA       VARCHAR2(32);DAY      VARCHAR2(100);MOUNTH   VARCHAR2(100);YEAR     VARCHAR2(100);HOUR     VARCHAR2(100);MINUTE   VARCHAR2(100);ValueReturn   VARCHAR2 (100);BEGINIF key = ' ' THENValueReturn := ' ';RETURN ValueReturn;ELSEDAY := SUBSTR(key,0,2);MOUNTH := SUBSTR(key,3,3);IF INSTR (MOUNTH,'JAN') > 0 THENMOUNTH := 01;END IF;IF INSTR (MOUNTH,'FEB') > 0 THENMOUNTH := 02;END IF;IF INSTR (MOUNTH,'MAR') > 0 THENMOUNTH := 03;END IF;IF INSTR (MOUNTH,'APR') > 0 THENMOUNTH := 04;END IF;IF INSTR (MOUNTH,'MAY') > 0 THENMOUNTH := 05;END IF;IF INSTR (MOUNTH,'JUN') > 0 THENMOUNTH := 06;END IF;IF INSTR (MOUNTH,'JUL') > 0 THENMOUNTH := 07;END IF;IF INSTR (MOUNTH,'AUG') > 0 THENMOUNTH := 08;END IF;IF INSTR (MOUNTH,'SEP') > 0 THENMOUNTH := 09;END IF;IF INSTR (MOUNTH,'OCT') > 0 THENMOUNTH := 10;END IF;IF INSTR (MOUNTH,'NOV') > 0 THENMOUNTH := 11;END IF;IF INSTR (MOUNTH,'DEC') > 0 THENMOUNTH := 12;END IF;YEAR := SUBSTR(key,6,2);HOUR := SUBSTR(key,8,2);MINUTE := SUBSTR(key,-2);AA := 20;--日月年時分(11OCT141017)ValueReturn := AA || YEAR || '-' || MOUNTH || '-' || DAY || ' ' || HOUR || ':' || MINUTE;--ValueReturn := HOUR || ':' || MINUTE;RETURN ValueReturn;END IF;END FormatDateValue;
/

三：建立插入數據表的存儲過程.sql:

CREATE OR REPLACE PROCEDURE MIP.PRO_TEST (xmlStr IN CLOB)
ISTIME    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;EXCEPTIONWHEN OTHERSTHENDBMS_OUTPUT.PUT_LINE (SQLERRM);END PRO_TEST;
/

四：建立行級觸發器.sql:

DROP TRIGGER MIP.COPY_TEST_TRIGGER;CREATE OR REPLACE TRIGGER MIP.COPY_TEST_TRIGGERAFTER INSERTON MIP.MBINMSGS    FOR EACH ROW
DECLARE
-- LOCAL VARIABLES HERE
BEGINPRO_TEST (:NEW.MBINMSGS_CLOB_MSG);
END COPY_TEST_TRIGGER;
/

五：給其中的原始數據表插入一條數據，查看是否解析成功并插入到對應的表中：

Insert into MBINMSGS(ID, MBINMSGS_CLOB_MSG, MBINMSGS_DATE_RECEIVED, MBINMSGS_DATE_PROCESSED, MBINMSGS_SUBSYSTEM_NAME, MBINMSGS_SUBSYSTEM_DATE_SENT, SERVICENAME)Values(1931300, '<?xml version="1.0" encoding="UTF-8"?>
<ASUPDATA><MSG>  <META>    <SNDR>DC</SNDR>    <DTTM>20141010230216</DTTM>    <TYPE>FLOP</TYPE>    <STYP>FGIS</STYP>  </META>  <FLOP>    <FFID>CA-CA1895-D-11OCT141730-D</FFID>    <TIME>11OCT141730</TIME>      </FLOP></MSG>
</ASUPDATA>', 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：查看對應的數據表中時間類型的字段是否有值：
