Question

我有一个非常复杂的问题。开发团队使用jdbc（区分大小写）编写了一个SQL脚本，该脚本在MySQL中搜索一个表。但是在MySQL中，表是用小写编写的，所以它会引发错误。

问题是开发团队不接受将表名更改为小写，并且开发团队不接受将表名更改为大写。

我知道我们可以使用lower_case_table_names to 1强制案例不敏感，但我没有权限重启mysqld。

我该怎么办？

Create view with Uppercase name 

    mysql> select * from f_val;
    ERROR 1146 (42S02): Table 'TEST.f_val' doesn't exist
    mysql> select * from F_VAL;
