To insert data into MySQL table you would need to use SQL INSERT INTO command. You can insert data into MySQL table by using mysql> prompt or by using any script like PHP.
Syntax:
Here is generic SQL syntax of INSERT INTO command to insert data into MySQL table:
INSERT INTO table_name ( field1, field2,...fieldN )
VALUES
( value1, value2,...valueN );
|
To insert string data types it is required to keep all the values into double or single quote, for example:- "value".
Inserting Data from Command Prompt:
This will use SQL INSERT INTO command to insert data into MySQL table tutorials_tbl
Example:
Following example will create 3 records into tutorials_tbl table:
root@host# mysql -u root -p password;
Enter password:*******
mysql> use TUTORIALS;
Database changed
mysql> INSERT INTO tutorials_tbl
->(tutorial_title, tutorial_author, submission_date)
->VALUES
->("Learn PHP", "John Poul", NOW());
Query OK, 1 row affected (0.01 sec)
mysql> INSERT INTO tutorials_tbl
->(tutorial_title, tutorial_author, submission_date)
->VALUES
->("Learn MySQL", "Abdul S", NOW());
Query OK, 1 row affected (0.01 sec)
mysql> INSERT INTO tutorials_tbl
->(tutorial_title, tutorial_author, submission_date)
->VALUES
->("JAVA Tutorial", "Sanjay", '2007-05-06');
Query OK, 1 row affected (0.01 sec)
mysql>
|
In the above example we have not provided tutorial_id because at the time of table create we had given AUTO_INCREMENT option for this field. So MySQL takes care of inserting these IDs automatically. Here NOW() is a MySQL function which returns current date and time.
Inserting Data Using PHP Script:
You can use same SQL INSERT INTO command into PHP function mysql_query() to insert data into a MySQL table.
Example:
This example will take three parameters from user and will insert them into MySQL table:
<html>
<head>
<title>Add New Record in MySQL Database</title>
</head>
<body>
<?php
if(isset($_POST['add']))
{
$dbhost = 'localhost:3036';
$dbuser = 'root';
$dbpass = 'rootpassword';
$conn = mysql_connect($dbhost, $dbuser, $dbpass);
if(! $conn )
{
die('Could not connect: ' . mysql_error());
}
if(! get_magic_quotes_gpc() )
{
$tutorial_title = addslashes ($_POST['tutorial_title']);
$tutorial_author = addslashes ($_POST['tutorial_author']);
}
else
{
$tutorial_title = $_POST['tutorial_title'];
$tutorial_author = $_POST['tutorial_author'];
}
$submission_date = $_POST['submission_date'];
$sql = "INSERT INTO tutorials_tbl ".
"(tutorial_title,tutorial_author, submission_date) ".
"VALUES ".
"('$tutorial_title','$tutorial_author','$submission_date')";
mysql_select_db('TUTORIALS');
$retval = mysql_query( $sql, $conn );
if(! $retval )
{
die('Could not enter data: ' . mysql_error());
}
echo "Entered data successfully\n";
mysql_close($conn);
}
else
{
?>
<form method="post" action="<?php $_PHP_SELF ?>">
<table width="600" border="0" cellspacing="1" cellpadding="2">
<tr>
<td width="250">Tutorial Title</td>
<td>
<input name="tutorial_title" type="text" id="tutorial_title">
</td>
</tr>
<tr>
<td width="250">Tutorial Author</td>
<td>
<input name="tutorial_author" type="text" id="tutorial_author">
</td>
</tr>
<tr>
<td width="250">Submission Date [ yyyy-mm-dd ]</td>
<td>
<input name="submission_date" type="text" id="submission_date">
</td>
</tr>
<tr>
<td width="250"> </td>
<td> </td>
</tr>
<tr>
<td width="250"> </td>
<td>
<input name="add" type="submit" id="add" value="Add Tutorial">
</td>
</tr>
</table>
</form>
