Oracle中通过游标执行带参数的存储过程实现解析CLOB字段内的xml字符串:

摘要：近来之前的项目数据出现了问题，原因是由于之前在设计数据库的时候把时间字段设置成了字符串格式，所以给后期的数据操作带来了很大的麻烦，这里提醒一下各位程序猿，以后在开发项目的时候时间字段一定要是时间字段，不要为了方便操作就设成字符串，这样后期改你带来的麻烦是你想象不到的，接下来就看看我解决这个问题的方法吧！

一：存储数据的零时表：


二：零时表里CLOB字段里面存储的xml字符串格式：












三：存储解析完成的xml的数据表：


四：执行解析CLOB字段里面xml字符串的存储过程SQL：

五：存储过程里面用到的Function.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)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;--日月年时分(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--创建xml解析器实例xmlparser.ParserxmlPar        xmlparser.Parser := xmlparser.newParser;--定义DOM文档xDoc          xmldom.DOMDocument;--定义item子节点数目变量lenItme       INTEGER;--定义节点列表，存放item节点们itemNodes     xmldom.DOMNodeList;--定义节点，存放单个item节点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);--将xmlPar中的数据转存到dom文档中xDoc := xmlparser.getDocument (xmlPar);--释放解析器实例xmlparser.freeParser (xmlPar);--获取所有item节点itemNodes := xmldom.getElementsByTagName (xDoc, nodeName);--获取item节点的个数lenItme := xmldom.getLength (itemNodes);--如果无该标签，则返回EMPTYIF lenItme = 0 THENValueReturn := ' ';ELSE--获取节点列表中的第1个item节点itemNode := xmldom.item (itemNodes, 0);--获取所有子节点的值ValueReturn := xmldom.getNodeValue (xmldom.getFirstChild (itemNode));END IF;   --释放domxmldom.freeDocument(xDoc);RETURN ValueReturn;END GetXmlNodeValue;
/


六：最后是调用存储过程执行解析Clob字段里面的xml字符串的游标SQL：

/* Formatted on 2015/1/15 14:20:27 (QP5 v5.115.810.9015) */
DECLARE--定义游标CURSOR c_cursorIS--这里查询指定时间内的数据，根据时间判断一下id>那个编号开始SELECT MBINMSGS_CLOB_MSG FROM MBINMSGS_TEMP;v_MBINMSGS_CLOB_MSG   MBINMSGS_TEMP.MBINMSGS_CLOB_MSG%TYPE;
BEGIN--打开游标OPEN c_cursor;--提取游标数据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;

总结：以上所以的SQL操作都是在PL/SQL中完成的，这样执行完成后的结果就是把零时表里面的所有的CLOB字段里面的xml解析并更新到对应的数据表中。
