To insert data into a MySQL table, you would need to use the SQL INSERT INTO command.
You can insert data into the MySQL table by using the mysql> prompt or by using any script like PHP.
Here are some syntax rules to follow:
- The SQL query must be quoted in PHP
- String values inside the SQL query must be quoted
- Numeric values must not be quoted
- The word NULL must not be quoted
INSERT INTO `table_name`(column_1,column_2,...) VALUES (value_1,value_2,...);- INSERT INTO `table_name` is the command that tells MySQL server to add new row into a table named `table_name`.
- (column_1,column_2,...) specifies the columns to be updated in the new row
- VALUES (value_1,value_2,...) specifies the values to be added into the new row
- String data types - all the string values should be enclosed in single quotes.
- Numeric data types - all numeric values should be supplied directly without enclosing them in single
- or double quotes.
- Date data types - enclose date values in single quotes in the format 'YYYY-MM-DD'.
Example
When supplying the data values to be inserted into the new table, the following should be considered while
dealing with different data types.
You can use the same SQL INSERT INTO command into the PHP function mysql_query() to
insert data into a MySQL table.
This example will take three parameters from the user and will insert them into the MySQL
table −
<html>
<head>
<title>Add New Record in MySQL Database</title>
</head>
<body>
<?php
if(isset($_POST['add'])) {
$dbhost = 'localhost';
$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 {
?>
