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:

男娘i 2024-02-17 15:27 45阅读 0赞

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：

![Center][]

二：零时表里CLOB字段里面存储的xml字符串格式：

![Center 1][]

三：存储解析完成的xml的数据表：

![Center 2][]

四：执行解析CLOB字段里面xml字符串的存储过程SQL：

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_cursor
       IS
          --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%FOUND
       LOOP
          DBMS_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。
