下面是我遇到的笔试题:
2Given the following table in MySQL. The table consists of 10,000 records
Employee Table
Field Type
emp_id char(6)
emp_firstname varchar(20)
emp_lastname varchar(20)
Emp_gender char(1)
emp_address varchar(255)
emp_joindate datetime
emp_birthday datetime
emp_remarks varchar(255)
Consider the SQL statement below and comment the size of result set in JDBC. What is the effect of result set when the number of record in Employee table growth?
SELECT * from Employee.
SELECT emp_id, emp_firstname, emp_lastname from Employee.
SELECT emp_id, emp_firstname, emp_lastname from Employee limit 1000, 25.
answer:
3If you have following batch of SQL:
Insert into table A values (123, 'Student A', 'Teacher B', 'Class C')
Insert into table B values (123, 'English', 'Grade A')
Insert into table B values (123, 'Math', 'Grade B')
If the third statement failed, how can you ensure the first and second statement will not be applied to the database too

在mysql的安装目录中找到my.ini配置设置文档添加

default-character-set=utf8
可在命令行中显示中文字符

1. 在命令行中 set names 'gbk':
2.
SELECT * from Employee.
10,000 records and all columns
SELECT emp_id, emp_firstname, emp_lastname from Employee.
10,000 records only column emp_id, emp_firstname, emp_lastname
SELECT emp_id, emp_firstname, emp_lastname from Employee limit 1000, 25.
record of employee from 1001 to 1024,and column emp_id, emp_firstname, emp_lastname
the 3rd is more effective.
2. use the transaction.
set autocommit=off
and then begin the transaction, after all SQL statement executed , commit.

为什么 gbk不行,我的default-character-set=GBK ?

打开命令行窗口输入mysql>set names"gbk";
再查询你要的东西,就能正确显示中文。我这里可以的。

在附件中,选择命令行窗口,再右键属性,选择字体为“宋体”
打开命令行窗口输入mysql>set names"gbk";
再查询你要的东西,就能正确显示中文。我这里可以的。
