Performing DataBase Operations in XAMPP
XAMPP is a cross-platform web server used to develop and test programs on a local server. It is developed and managed by Apache Friends and is open-source. It has an Apache HTTP Server, MariaDB, and interpreter for 11 different programming languages like Perl and PHP. XAMPP Stands for cross-platform, Apache, MySQL, PHP, and Perl.
- It allows you to build a website on a local web server on your computer.
- Stores data locally
In this article, we are going to perform Database operations like Create, Insert, Update, Delete data from the database created in XAMPP localhost server. We are also going to create a table and then start performing database operations. Following are the list of database operations with their respective syntax:
It is used to display all the details from the table.
Syntax: SELECT * FROM 'table_name'
It is used to insert data into the table.
Syntax: INSERT INTO `table_name`(`col`, `col2`, `col3`,.. `coln`) VALUES ([value-1],[value-2], [value-3],....,[value-n)
It is used to change/update any data in the table.
Syntax: UPDATE `table_name` SET `col1`=[value-1], `col2`=[value-2], `col3`=[value-3], `coln`=[value-n] WHERE 1
It is used to delete data from a table.
Syntax: DELETE FROM table_name where col="value"
Follow the below steps to perform database operations on XAMPP:
- Start XAMPP Server
- Create Database and Create Table
- Perform Database Operations
- Verify Resultant Table
Steps to Create a Database:
1. Start XAMPP server
2. Go to Browser and type “http://localhost/phpmyadmin” and Create a database with the name “Vignan” by selecting new
3. After that, Create table Name “ITDept” and give the number of columns (I created 4 columns) and click on Go
Give column names as “Rollno”(Varchar), “Name”(Varchar), “Gender” (Char), “Address”(Varchar), and Save.
Note: Clicking the “Save” option is important, if not the table is not created.
Then we get the output as:
Performing SQL Operations:
- Click on SQL
- Click on INSERT Option
By default, code is available like this:
INSERT INTO `itdept`(`Rollno`, `Name`, `Gender`, `Address`) VALUES ([value-1],[value-2],[value-3],[value-4])
- We want to modify the values as follows and click on “GO”
INSERT INTO `itdept`(`Rollno`, `Name`, `Gender`, `Address`) VALUES ("171FA07058","Sravan Kumar Gottumukkala", "m", "HYD" )
- Now insert 5 records. Data in the database is as follows:
Default code in the update is:
UPDATE `itdept` SET `Rollno`=[value-1], `Name`=[value-2], `Gender`=[value-3], `Address`=[value-4] WHERE 1
- Now change the name to Sujatha where rollno is 171FA07078 as follows:
UPDATE `itdept` SET NAME="Sujitha" WHERE `Rollno`="171FA07078"
The Select statement is used to display or query for data from the database. Follow the below steps to do so:
- Click on the Select* option
This will result in the following code generation:
SELECT * FROM `itdept`
For Selecting particular data follow the below sample query:
Select Rollno, Name from itept
- Click on the Delete button to delete the data as shown below:
The generated code would look like below:
DELETE FROM itdept where Rollno="171FA07058"
- Confirm the deletion by clicking YES
Our Final data in Table is:
