MySQL Create DB
A database holds one or multiple tables.
Create a Database
The CREATE DATABASE statement is used to create a database in MySQL.
Syntax
CREATE DATABASE database_name
Example
The following example creates a database called "my_db":<?php
$con = mysql_connect("localhost","peter","abc123");
if (!$con)
{
die('Could not connect: ' . mysql_error());
}
if (mysql_query("CREATE DATABASE my_db",$con))
{
echo "Database created";
}
else
{
echo "Error creating database: " . mysql_error();
}
mysql_close($con);
?>
Create a Table
The CREATE TABLE statement is used to create a table in MySQL.
Syntax
CREATE TABLE table_name ( column_name1 data_type, column_name2 data_type, column_name3 data_type, .... )
We must add the CREATE TABLE statement to the mysql_query() function to execute the command.
Example
The following example creates a table named "Persons", with three columns. The column names will be "FirstName", "LastName" and "Age":<?php
$con = mysql_connect("localhost","peter","abc123");
if (!$con)
{
die('Could not connect: ' . mysql_error());
}
// Create database
if (mysql_query("CREATE DATABASE my_db",$con))
{
echo "Database created";
}
else
{
echo "Error creating database: " . mysql_error();
}
// Create table
mysql_select_db("my_db", $con);
$sql = "CREATE TABLE Persons
(
FirstName varchar(15),
LastName varchar(15),
Age int
)";
// Execute query
mysql_query($sql,$con);
mysql_close($con);
?>
The data type specifies what type of data the column can hold. For a complete reference of all the data types available in MySQL, go to complete Data Types reference.
