MySQLi - Insert Query


Advertisements


To insert data into MySQLi table, you would need to use SQL INSERT INTO command. You can insert data into MySQLi 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 MySQLi 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 MySQLi table tutorials_inf.

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_inf 
   ->(id, name)
   ->VALUES
   ->(10, "John Poul");
Query OK, 1 row affected (0.01 sec)

NOTE − Please note that all the arrow signs (->) are not part of SQL command; they are indicating a new line and they are created automatically by MySQL prompt while pressing enter key without giving a semicolon at the end of each line of the command.

Inserting Data Using PHP Script

You can use same SQL INSERT INTO command into PHP function mysqli_query() to insert data into a MySQLi table.

Example

This example will take three parameters from user and will insert them into MySQLi table −

<html>
   <head>
      <title>Add New Record in MySQLi Database</title>
      <link rel = "stylesheet" type = "text/css" href = "style.css">
   </head>
   
   <body>
      <div id = "main">
         <form action = "" method = "post">
            <label>Name :</label>
            <input type = "text" name = "name" id = "name" />
            <br />
            <br />
            <input type = "submit" value ="Submit" name = "submit"/>
            <br />
         </form>
      </div>
      
      <?php
         if(isset($_POST["submit"])){
            $servername = "localhost:3306";
            $username = "root";
            $password = "<Password here>";
            $dbname = "TUTORIALS";

            // Create connection
            $conn = new mysqli($servername, $username, $password, $dbname);

            // Check connection
            if ($conn->connect_error) {
               die("Connection failed: " . $conn->connect_error);
            } 
            $sql = "INSERT INTO tutorials_inf(name)VALUES ('".$_POST["name"]."')";

            if (mysqli_query($conn, $sql)) {
               echo "New record created successfully";
            } else {
               echo "Error: " . $sql . "" . mysqli_error($conn);
            }
            $conn->close();
         }
      ?>
   </body>
</html>

The sample output should be like this −

New record created successfully
