Basics mysql learning 01

Probably looked a week ago mysql database video Yan eighteen teacher to explain, but also to go with for a week, I just want what they have learned this week I share with you; because it is the first time to write blog, you might write sucks, please bear with me. The article wrong place also please point it out, I will be corrected.

Let's learn to connect to the database and the table basic CRUD:

First to connect and login to the database server:

At the command line, type: mysql -uroot -p

Then enter the password, if you forget the password, then you can perform the following operations:

The library began to learn the basic statement of operations:

The first is to see what our clients have libraries: show databases;

Then create a new library: create database database name;

To delete a library: drop database database name;

Select a library: use the library name;

Then Again database can not be renamed, as we have seen some clients seems to be able to change the fact that it is only a first built, like the original table structure of the database, then put the old library to delete.

The operation of the library is finished down operations on the table:

We chose a library and then view it inside the table:

Then we can build a simple new table (for example, enrollment form):

create table stu(

Finding an int,

Sname varchar(10)

)engine myisam charset utf8;

Because it is just beginning to learn, so do not tangle in the end it is how to build the table, and then we'll come back, now on the table to understand the basic operation of the line.

View the table: select * from stu;

We can see just completed table does not have any data, which is, of course, because we do not have to insert data inside Well, if the data is actually strange.

Next we insert data to the inside:

insert into stu
