Creating Your First Database


31/57

Step by Step> Command Basics> Create a database

> Create a table> Load data into the table> Retrieve data from the table in various ways


32/57

32

Command Basics

mysql> select version();

+------------------+

| version() |

+------------------+

| 5.1.46-community |+------------------+

1 row in set (0.00 sec)

A command normally consists of an SQL statement

followed by a semicolon

When you issue a command, mysql sends it to the serverfor execution and displays the results, then prints another

mysql>prompt to indicate that it is ready for anothercommand


33/57

33

Command Basics

Keywords may be entered in any lettercase

A command need not be given all on a single line, solengthy commands that require several lines are not aproblem

MySQLdetermines where your statement ends bylooking for the terminating semicolon, not by lookingfor the end of the input line.

mysql> select

-> user()

-> ,

-> current_date;


34/57

34

Command Basics

Prompt Meaning

mysql> Ready for new command

-> Waiting for next line of multiple-line command

'> Waiting for next line, waiting for completion of a string that began with a singlequote (')

> Waiting for next line, waiting for completion of a string that began with adouble quote (")

`> Waiting for next line, waiting for completion of an identifier that began with abacktick (`)

/*> Waiting for next line, waiting for completion of a comment that began with /*


35/57

35

Command Basics

If you decide you do not want to execute a command thatyou are in the process of entering, cancel it by typing \c

mysql> SELECT

-> USER()

-> \c

Step 1. Creating the Database


37/57

37

Creating Your First Databasemysql> create database mysqlug;

Query OK, 1 row affected (0.04 sec)

mysql> show databases;

+--------------------+

| Database |+--------------------+

| mysqlug |

+--------------------+

1 rows in set (0.01 sec)

mysql> use mysqlug;

Database changed

mysql> GRANT ALL ON mysqlug.* TO 'seighman'@'localhost';


38/57

Step 2. Creating Tables


39/57

39


mysql> show tables;Empty set (0.00 sec)


40/57

40


mysql> create table members

-> (lastname varchar(20),

-> firstname varchar(20),

-> address varchar(30),

-> city varchar(20),-> state varchar(2),

-> zip int(5),

-> phone int(12),

-> email varchar (40));

Query OK, 0 rows affected (0.17 sec)

mysql>


41/57

mysql> show tables;

+-------------------+

| Tables_in_mysqlug |

+-------------------+

| members |+-------------------+

1 row in set (0.00 sec)


42/57

mysql> describe members;

+-----------+-------------+------+-----+---------+-------+

| Field | Type | Null | Key | Default | Extra |

+-----------+-------------+------+-----+---------+-------+

| lastname | varchar(20) | YES | | NULL | |

| firstname | varchar(20) | YES | | NULL | || address | varchar(30) | YES | | NULL | |

| city | varchar(20) | YES | | NULL | |

| state | varchar(2) | YES | | NULL | |

| zip | int(5) | YES | | NULL | |

| phone | int(12) | YES | | NULL | |

| email | varchar(40) | YES | | NULL | |

+-----------+-------------+------+-----+---------+-------+

Step 3. Loading Data


44/57

44

Loading Data

You could create a text file members.txt containing onerecord per line, with values separated by tabs, and givenin the order in which the columns were listed in theCREATE TABLE statement (use \N for NULL fields):lastname firstname address city state phone email

mysql> LOAD DATA LOCAL INFILE 'members.txt' INTO TABLEmembers;

If you created the file on Windows with an editor that

uses \r\n as a line terminator, you should use thisstatement instead:

mysql> LOAD DATA LOCAL INFILE 'members.txt' INTO TABLEpet LINES TERMINATED BY '\r\n';


45/57

45

Loading Data

You could export a .csv file from an Excel spreadsheetcontaining one record per line, with values separated bycommas, and given in the order in which the columnswere listed in the CREATE TABLE statement

mysql> LOAD DATA LOCAL INFILE 'members.csv' INTO TABLEmembers FIELDS TERMINATED BY ',';

If you created the file on Windows with an editor thatuses \r\n as a line terminator, you should use this

statement instead:

mysql> LOAD DATA LOCAL INFILE 'members.csv' INTO TABLEmembers FIELDS TERMINATED BY ',' LINES TERMINATED BY'\r\n';


46/57

Sample Databases$ mysql -u root -p

Enter password:

Welcome to the MySQL monitor. Commands end with ; or \g.

Your MySQL connection id is 39

Server version: 5.1.31-1ubuntu2 (Ubuntu)

Type 'help;' or '\h' for help. Type '\c' to clear the buffer.

mysql> create database world;

mysql> use world;

Database changed

mysql> source /home/Documents/world.sql;

Step 4. Retrieving Data

R t i i D t


52/57

52

Retrieving Data

The SELECT statement is used to pull informationfrom a table. The general form of the statement is:

SELECT what_to_select

FROMwhich_table

WHERE conditions_to_satisfy;

what_to_selectindicates what you want to see> List of columns, or* to indicate all columns.

which_table indicates the table from which you want toretrieve data

The WHERE clause is optional. If it is present,conditions_to_satisfyspecifies one or more conditionsthat rows must satisfy to qualify for retrieval.

R t i i D t


53/57

53

Retrieving Data

mysql> SELECT * FROMmembers;

Find all data in the table

mysql> SELECT COUNT(*) FROM members;

Count all rows in the table

mysql> SELECT name, email FROM members;

Find names and emails

mysql> SELECT city, COUNT(*) FROM members GROUP BY city;

Display the count of cities

R t i i D t


54/57

54

Retrieving Data

mysql> SELECT lastname, firstname FROM members ORDER BYfirstname;

Find first names and last names, sort by first names

mysql> SELECT * FROM members WHERE name LIKE 'b%';

Find names beginning with the letter 'b'

mysql> SELECT * FROM members WHERE name LIKE '%fy';

Find names ending with the letters 'fy'

mysql> SELECT * FROM members WHERE name LIKE '%w%';

Find names containing the letter 'w'
