数字求和 1到100 两个页面

用javascript实现1到100数字的求和，并通过值的传递求得，发到服务器端，求出值

是的，这条 SQL 查询语句存在语法错误。应该将 `round(10183/100,0)` 改为 `ROUND(10183/100,0)`。同时，如果想要正确地执行此查询语句，还需要在 `dual` 表中加入一列数据，可以使用以下语句来添加： ``` SELECT rownum, 'dummy' FROM dual CONNECT BY level <= 10183 ``` 然后将这两条语句合并，得到正确的查询语句： ``` SELECT rownum page, 100 number FROM ( SELECT rownum, 'dummy' FROM dual CONNECT BY level <= 10183 ) WHERE rownum <= ROUND(10183/100,0)*100 ```
