摘要：接着之前的问题，在Oracle数据库中通过Function，存储过程，触发器实现解析数据表中CLOB大数据字段中存在的xml字符串有时，有个特殊的时间字符串要在数据库格式化处理，之前解析过来的时间字符串是，比如：11OCT141024表示:(日月年时分)，这是一种不规则的时间格式，我们要把它格式化成:(年-月-日 时:分)这样的格式，就的再另外写个Function来特殊处理了，下面我把我的方法写上，关于Oracle中解析Clob字段中的xml字符串的方式请看上一篇博客
一：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)
AA VARCHAR2(32);
DAY VARCHAR2(32);
MOUNTH VARCHAR2(32);
YEAR VARCHAR2(32);
HOUR VARCHAR2(32);
MINUTE VARCHAR2(32);
ValueReturn VARCHAR2 (100);
BEGIN
IF key IS NULL THEN
ValueReturn := NULL;
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;
RETURN ValueReturn;
END IF;
END FormatDateValue;
