摘要：近來之前的項目數據出現了問題，原因是由于之前在設計數據庫的時候把時間字段設置成了字符串格式，所以給后期的數據操作帶來了很大的麻煩，這里提醒一下各位程序猿，以后在開發項目的時候時間字段一定要是時間字段，不要為了方便操作就設成字符串，這樣后期改你帶來的麻煩是你想象不到的，接下來就看看我解決這個問題的方法吧！

一：存儲數據的零時表：

二：零時表里CLOB字段里面存儲的xml字符串格式：

三：存儲解析完成的xml的數據表：

四：執行解析CLOB字段里面xml字符串的存儲過程SQL：

五：存儲過程里面用到的Function.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)Str VARCHAR2(32);AA VARCHAR2(32);DAY VARCHAR2(32);MOUNTH VARCHAR2(32);YEAR VARCHAR2(32);HOUR VARCHAR2(32);MINUTE VARCHAR2(32);ValueReturn VARCHAR2 (64);BEGINIF key != ' ' THENDAY := 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;Str := 0;--日月年時分(11OCT141017)IF length(MOUNTH) < 2 THENMOUNTH := Str||MOUNTH;ValueReturn := AA || YEAR || '-' || MOUNTH || '-' || DAY || ' ' || HOUR || ':' || MINUTE;ELSEValueReturn := AA || YEAR || '-' || MOUNTH || '-' || DAY || ' ' || HOUR || ':' || MINUTE;END IF;--ValueReturn := HOUR || ':' || MINUTE;RETURN ValueReturn;ELSEValueReturn := ' ';RETURN ValueReturn;END IF;END FormatDateValue; /
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; /

六：最后是調用存儲過程執行解析Clob字段里面的xml字符串的游標SQL：

/* Formatted on 2015/1/15 14:20:27 (QP5 v5.115.810.9015) */ DECLARE--定義游標CURSOR c_cursorIS--這里查詢指定時間內的數據，根據時間判斷一下id>那個編號開始SELECT MBINMSGS_CLOB_MSG FROM MBINMSGS_TEMP;v_MBINMSGS_CLOB_MSG MBINMSGS_TEMP.MBINMSGS_CLOB_MSG%TYPE; BEGIN--打開游標OPEN c_cursor;--提取游標數據FETCH c_cursor INTO v_MBINMSGS_CLOB_MSG;WHILE c_cursor%FOUNDLOOPDBMS_OUTPUT.put_line (v_MBINMSGS_CLOB_MSG);FETCH c_cursor INTO v_MBINMSGS_CLOB_MSG;MIP_PARSE(v_MBINMSGS_CLOB_MSG);END LOOP; END;
總結：以上所以的SQL操作都是在PL/SQL中完成的，這樣執行完成后的結果就是把零時表里面的所有的CLOB字段里面的xml解析并更新到對應的數據表中。
