Stored Procedure In PHP
A stored procedure is a set of SQL commands that have been compiled and stored on the database server.
Once the stored procedure has been “stored”, client applications can execute the stored procedure over and over again without sending it to the database server again and without compiling it again.
Stored procedures improve performance by reducing network traffic and CPU load.
Comparison with dynamic SQL
- Remove overhead
- Avoidance of network traffic
- Encapsulation of business logic
- Delegation of access-rights
- Some protection from SQL injection attacks
How To Create And Execute SP
There are various options that can be used to create stored procedures. In these next few topics we will discuss creating a stored procedure and How to execute.
Syntax –
|
1 2 3 4 5 6 7 8 9 10 11 12 13 14 |
Create Proc SP_Name ( Param1 DataType, param2 DataType, Param3 DataType, . . . Paramn DataType ) As Begin Body Of Store Procedure End |
How to insert Data into Database Using Stored Procedure
Create a Sql Table with name user. Structure of the user table given below….
|
1 2 3 4 5 6 7 |
CREATE TABLE `user` ( `id` int(11) NOT NULL, `name` varchar(255) NOT NULL, `email` varchar(255) NOT NULL, `contactno` bigint(11) NOT NULL, `addrss` longtext NOT NULL ) ENGINE=InnoDB DEFAULT CHARSET=latin1; |
Now create a database connection
|
1 2 3 4 5 6 7 8 9 10 11 12 |
<?php define('DB_SERVER','localhost'); define('DB_USER','root'); define('DB_PASS' ,''); define('DB_NAME', 'test'); $con = mysqli_connect(DB_SERVER,DB_USER,DB_PASS,DB_NAME); // Check connection if (mysqli_connect_errno()) { echo "Failed to connect to MySQL: " . mysqli_connect_error(); } ?> |
Create a stored Procedure with name insertuser.
|
1 2 3 4 |
DELIMITER $ CREATE PROCEDURE insertuser (IN name VARCHAR(255), IN email VARCHAR(255), IN contactno BIGINT, IN addrss LONGTEXT) insert into user(name,email,contactno,addrss) VALUES(name,email,contactno,addrss)$ |
Argument Modes
IN : Data Values comes in form the calling process and is not changed.
OUT : No Data Value comes in form the calling process; on normal exit, value of argument is passed back to caller.
IN OUT : Data Values comes in form the calling process, and another value is returned on normal exit.
Now create a HTML form (Index.php)
|
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 |
<form name="stmt" method="post"> <table> <tr> <td>Name :</td> <td><input type="text" name="name" required="required" /> </td> </tr> <tr> <td>Email :</td> <td><input type="email" name="email" required="required" /></td> </tr> <tr> <td>Contact no. :</td> <td><input type="text" name="contact" required="required" /></td> </tr> <tr> <td>Address :</td> <td><textarea name="addrss" cols="30" rows="4" required="required"></textarea></td> </tr> <tr> <td></td> <td><input type="submit" name="submit" value="Submit" /></td> </tr> </table> </form> |
Now execute the store Procedure. Put this on the top of the index Page
|
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 |
<?php include('config.php'); if(isset($_POST['submit'])) { $name=$_POST['name']; $email=$_POST['email']; $contact=$_POST['contact']; $addrss=$_POST['addrss']; // Code for execute the Store Procedure $sql=mysqli_query($con,"CALL insertuser('$name','$email','$contact','$addrss')"); if($sql) { echo "<script>alert('Data Inserted');</script>"; } else { echo "<script>alert('not inserted');</script>"; } } ?> |
How to run demo on localhost
