使用Aqua Data Studio遇到以下几个问题：
（1）select * from orders:
一般写SQL都习惯在每个SQL后面加上分号。这时会出现如下错误：
>[Error] Script lines: 7-7 --------------------------
An unexpected token "" was found following "". Expected tokens may include: "select * from orders".. SQLCODE=-104, SQLSTATE=42601, DRIVER=3.61.75
More exceptions ... An error occurred during implicit system action type "2". Information returned for the error includes SQLCODE "-104", SQLSTATE "42601" and message tokens "".. SQLCODE=-727, SQLSTATE=56098, DRIVER=3.61.75

2、乱码问题：查询结果出现乱码，修改字体即可。
