How to Select From Mysql table With Escapable Characters

Question

i am trying to select tables from my mysql database , and the tables names may be any thing unsafe, since users choose them, i have tried to do it like this :

String table = "*jjs> o";
PreparedStatement stmt = conn.PrepareStatement("SELECT * FROM ? ");
stmt.setString(1,table);
stmt.executeQuery();

but seems it to throw exception due to unacceptable command, can some one help me how can i achieve that please? thanks

Answer 1

在表名中添加反勾号（`）

select * from `*jjs> o`

Answer 2

可以使用BackTicks很好，就像没有声明的select * from `*jjs> o`一样。
