你好,如果格式都如你贴图的一样的话可以用这种最笨的方式全一个个化成数值型,然后相加取值。

如果格式不统一,建议如2楼的,把字符型中的‘/’全部替换成‘+’,然后拼接出来一个sql,执行处理。
望采纳,谢谢。
可以参考如下:

(T_DATA DATE,
T_NAME VARCHAR2(10),
T_SCORE NUMBER(10)
) ;
INSERT INTO TEMP_AVG_SCORE VALUES (TO_DATE('2015-01-01','YYYY-MM-DD'),'A',30) ;
INSERT INTO TEMP_AVG_SCORE VALUES (TO_DATE('2015-01-10','YYYY-MM-DD'),'A',40) ;
