Thanks for watching Emer
Is there option to make php script or something similar, like you can do in xampp with placing php script in htdocs?
Yes, you can run PHP scripts on your local machine by setting up a web server environment like XAMPP or WAMP. Here's how you can do it:
Install XAMPP (or WAMP): Download and install XAMPP (or WAMP) from the official website. These packages provide a complete web server environment that includes PHP, Apache, MySQL, and other necessary components.
Start the server: Once installed, start the Apache server from the XAMPP control panel (or WAMP control panel).
Create a PHP script: In the XAMPP installation directory, you will find a folder named "htdocs" (for XAMPP) or "www" (for WAMP). Place your PHP script in this folder or create a subfolder to organize your scripts.
Access the PHP script: Open your web browser and type "localhost" in the address bar. If everything is set up correctly, it will display the XAMPP (or WAMP) default page. To run your PHP script, you can access it by navigating to localhost//.php in the browser.
For example, if you have a script named "my_script.php" located in a folder named "scripts" inside the "htdocs" (or "www") folder, you can access it using localhost/scripts/my_script.php.
By following these steps, you can run PHP scripts locally on your machine using XAMPP (or WAMP). Remember to start the server each time you want to run PHP scripts in your local web server environment.
finally thanks fr

Hi , Please make a video on running spring boot/java application for free on remote
Sure Vikas, I will check
Hie Sir..Great video..i have a java project and I want to use the online data so my software can access it when i install on another pc..how do I connect it with this database..im supposed to submit it as my school project..im currently using wampserver so its only running on my pc..thank you
Connecting your Java project to an online MySQL database hosted on freesqldatabase.com involves a few steps. Let's break it down:
1. Database Setup on freesqldatabase.com:
- First, create an account on [freesqldatabase.com](www.freesqldatabase.com/).
- Log in and create a new database. Note down the database name, username, and password provided by the hosting service.
2. Java Code Configuration:
- In your Java project, you'll need to use the MySQL JDBC driver to connect to the remote database.
- Make sure you have the MySQL Connector/J library (JDBC driver) added to your project. If not, download it from [here](dev.mysql.com/downloads/connector/j/) and add it to your classpath.
3. Connecting to the Remote Database:
- Replace the placeholders in the following code snippet with your actual database details:
```java
import java.sql.Connection;
import java.sql.DriverManager;
import java.sql.SQLException;
public class DatabaseConnection {
public static void main(String[] args) {
String url = "jdbc:mysql://sql5.freesqldatabase.com:3306/your-database-name"; // Replace with your database URL
String username = "your-username"; // Replace with your database username
String password = "your-password"; // Replace with your database password
try {
// Load the MySQL driver
Class.forName("com.mysql.cj.jdbc.Driver");
// Establish the connection
Connection connection = DriverManager.getConnection(url, username, password);
// Now you can execute queries or perform other database operations
// For example:
// connection.createStatement().execute("SELECT * FROM your_table");
// Close the connection when done
connection.close();
System.out.println("Connected successfully!");
} catch (ClassNotFoundException | SQLException e) {
e.printStackTrace();
System.err.println("Error connecting to the database.");
}
}
}
```
4. Testing the Connection:
- Compile and run the above Java class. If everything is set up correctly, it should connect to your remote database.
- Make sure your hosting provider allows remote connections. Some providers restrict external access for security reasons. If you encounter issues, check with your hosting support.
5. Security Considerations:
- Ensure that your database credentials (username and password) are kept secure. Avoid hardcoding them directly in your code; consider using environment variables or configuration files.
- Use prepared statements to prevent SQL injection attacks.
Remember to replace the placeholders (`your-database-name`, `your-username`, and `your-password`) with your actual database information.
Good luck with your school project
@@RaghavPal Thank You sir..we need more people like you🙏
How can i connect my java program to this database? What should i write in my maven dependency and what should i write in Class.forName for this ? Please reply , Urgent help needed.
Hi Sarvesh
This is a test db with minimal features, space and speed, It may not work very smoothly, but still if you want to try for testing purpose, here is some Java code to connect to a SQL database:
```java
import java.sql.*;
public class SQLDatabaseConnection {
public static void main(String[] args) throws SQLException {
// Load the JDBC driver
try {
Class.forName("com.mysql.jdbc.Driver");
} catch (ClassNotFoundException e) {
System.out.println("Error loading JDBC driver: " + e.getMessage());
return;
}
// Create a connection to the database
String url = "jdbc:mysql://localhost:3306/mydatabase";
String username = "root";
String password = "password";
Connection connection = DriverManager.getConnection(url, username, password);
// Do something with the connection
Statement statement = connection.createStatement();
ResultSet resultSet = statement.executeQuery("SELECT * FROM users");
while (resultSet.next()) {
System.out.println(resultSet.getString("username"));
}
// Close the connection
connection.close();
}
}
```
This code will connect to a MySQL database on the local machine. The username and password are hardcoded, but you can replace them with your own credentials.
The `Class.forName()` method loads the JDBC driver for MySQL. The `DriverManager.getConnection()` method creates a connection to the database. The `Statement.executeQuery()` method executes a SQL query and returns a `ResultSet` object. The `ResultSet.next()` method advances the `ResultSet` object to the next row. The `ResultSet.getString()` method returns the value of a column in the current row.
Once you have finished working with the database, you should close the connection using the `Connection.close()` method.
I hope this helps
Hi sir, thank you for the tutorial. But can i know how to connect mysql in cloud with python code in local server
Hi Nur
If I get sometime, I will plan to do a session, for now you can check and try with some online examples
amazing! and how can i change my DB name ?
To change the name of your database on FreeSqlDatabase, follow these steps:
1. Log In to FreeSqlDatabase:
- Visit the [FreeSqlDatabase website](www.freesqldatabase.com/).
- Log in using your credentials.
2. Access Your Database:
- Once logged in, navigate to your existing database that you want to rename.
3. Database Renaming:
- Look for an option related to database management or settings.
- There should be an option to rename the database.
- Provide the new name you want for your database and confirm the change.
4. Save Changes:
- Save your changes, and the database will now have the new name.
Remember to adjust the steps based on the specific interface provided by FreeSqlDatabase. If you encounter any issues, refer to their documentation
thanks man nice video, but how do i grant access the database?
Once you setup the DB, you can use it, I did not get exactly what access do you need, can send more details. In General:
Connecting your project to a MySQL database involves establishing a connection from your application code to the database server. I'll provide instructions for different programming languages and environments:
1. PHP:
- If you're using PHP, you can connect to a MySQL database using either the MySQLi extension (object-oriented or procedural) or PDO (PHP Data Objects).
- Here are examples for both approaches:
- MySQLi (Object-Oriented):
```php
```
- MySQLi (Procedural):
```php
```
- PDO:
```php
```
2. Node.js:
- For connecting a Node.js application to a MySQL database, you'll need the mysql module.
- Initialize your Node.js project, download the mysql module, and create a connection using the `createConnection()` method.
- Example:
```javascript
const mysql = require("mysql");
const connection = mysql.createConnection({
host: "localhost",
user: "your_username",
password: "your_password",
database: "your_database"
});
connection.connect((err) => {
if (err) {
console.error("Error connecting to MySQL:", err);
return;
}
console.log("Connected to MySQL!");
});
```
3. Java:
- In Java, you can use JDBC (Java Database Connectivity) to connect to a MySQL database.
- Make sure you have the MySQL JDBC driver (Connector/J) in your project.
- Example:
```java
import java.sql.Connection;
import java.sql.DriverManager;
import java.sql.SQLException;
public class Main {
public static void main(String[] args) {
String url = "jdbc:mysql://localhost:3306/your_database";
String username = "your_username";
String password = "your_password";
try {
Connection conn = DriverManager.getConnection(url, username, password);
System.out.println("Connected to MySQL!");
} catch (SQLException e) {
System.err.println("Connection failed: " + e.getMessage());
}
}
}
```
Remember to replace `"your_username"`, `"your_password"`, and `"your_database"` with your actual database credentials. Once connected, you can execute queries and interact with your MySQL database.

@@RaghavPal Can we expect more in future on the same
Could you please assist me in finding the driver and driver class for this database?
Prasanth
1. Database Type:
- The database provided by FreeSQLDatabase.com is MySQL-based. Therefore, you'll need the MySQL ODBC driver to connect to it.
2. Driver and Connection String:
- To connect to your FreeSQLDatabase.com database using Classic ASP, you can use the following connection string:
```asp
set conn=Server.CreateObject("ADODB.Connection")
conn.Open "Driver={MySQL ODBC 5.2 UNICODE Driver};Server=sql3.freesqldatabase.com;Database=dbname;User=username;Password=password;Option=3;"
```
Replace `dbname`, `username`, and `password` with your actual database name, username, and password provided by FreeSQLDatabase.com.
- Note that the version number in the driver name (`MySQL ODBC 5.2 UNICODE Driver`) should match the version you have installed on your server
3. Port Number:
- Make sure to include the correct port number in your connection string if you intend to connect remotely via TCP/IP. If FreeSQLDatabase.com specifies a port number, add it to the connection string:
```asp
conn.Open "Driver={MySQL ODBC 5.2 UNICODE Driver};Server=sql3.freesqldatabase.com;Database=dbname;Port=1234;User=username;Password=password;Option=3;"
```
Replace `1234` with the actual port number provided by FreeSQLDatabase.com.
Remember to replace placeholders with your actual database details, and you should be able to connect successfully.

#1071 - Specified key was too long; max key length is 767 bytes in sql free online how to solve it . Thanks
Hi Thành
The "Specified key was too long; max key length is 767 bytes" error usually occurs when you are trying to create an index or key on a column that exceeds the maximum length allowed by your database's configuration. This issue is common in MySQL when using the InnoDB storage engine.
To solve this issue, you can try one of the following approaches:
1. Adjust the column length: If the column causing the issue is not required to be that long, you can reduce its length to fit within the maximum key length limit. Alter the table and modify the column length accordingly.
2. Change the database configuration: By default, MySQL uses the UTF-8 encoding for character sets, which requires more space. You can switch to a different character set like UTF8MB4, which allows longer key lengths. However, note that changing the character set might impact other aspects of your application, so it's important to test and ensure compatibility.
3. Use a different database engine: If changing the character set or column length doesn't solve the issue, you can consider using a different database engine that supports longer key lengths. For example, you can switch to MyISAM instead of InnoDB, as MyISAM has a higher limit for key length.
4. Use prefix indexes: If you need to index a long column and reducing its length is not feasible, you can create a prefix index. This index only uses the first few characters of the column for indexing, effectively reducing the key length. However, note that prefix indexes have limitations and might impact performance, so use them judiciously.
Remember to backup your database before making any changes, especially if you are modifying table structures or switching database engines.
How to connect database using JDBC API
To connect to a database using the JDBC API, you can follow these steps:
Load the JDBC driver for the database you want to connect to using the Class.forName() method. For example, if you want to connect to a MySQL database, you would load the MySQL JDBC driver using the following code:
Class.forName("com.mysql.jdbc.Driver");
Establish a connection to the database using the DriverManager.getConnection() method. You need to provide the connection URL, username, and password as arguments to this method. The connection URL varies depending on the type of database you are connecting to. For example, to connect to a MySQL database, you would use a connection URL like this:
java
String url = "jdbc:mysql://localhost:3306/mydatabase";
String user = "myuser";
String password = "mypassword";
Connection connection = DriverManager.getConnection(url, user, password);
Once you have established a connection, you can create a Statement object using the Connection.createStatement() method. This object allows you to execute SQL queries and retrieve results from the database. For example, to retrieve all records from a table called "customers", you can use the following code:
Statement statement = connection.createStatement();
ResultSet resultSet = statement.executeQuery("SELECT * FROM customers");
You can then use the ResultSet object to retrieve data from the database. For example, to retrieve the value of a column called "name" from the first row of the result set, you can use the following code:
resultSet.next();
String name = resultSet.getString("name");
After you have finished working with the database, you should close the ResultSet, Statement, and Connection objects in reverse order of creation using their close() methods. For example:
resultSet.close();
statement.close();
connection.close();
These are the basic steps for connecting to a database using the JDBC API. There are also more advanced features available, such as prepared statements and transactions, which can help improve performance and ensure data consistency.
But how to connect with my project??
Connecting your project to a MySQL database involves establishing a connection from your application code to the database server. I'll provide instructions for different programming languages and environments:
1. PHP:
- If you're using PHP, you can connect to a MySQL database using either the MySQLi extension (object-oriented or procedural) or PDO (PHP Data Objects).
- Here are examples for both approaches:
- MySQLi (Object-Oriented):
```php
```
- MySQLi (Procedural):
```php
```
- PDO:
```php
```
2. Node.js:
- For connecting a Node.js application to a MySQL database, you'll need the mysql module.
- Initialize your Node.js project, download the mysql module, and create a connection using the `createConnection()` method.
- Example:
```javascript
const mysql = require("mysql");
const connection = mysql.createConnection({
host: "localhost",
user: "your_username",
password: "your_password",
database: "your_database"
});
connection.connect((err) => {
if (err) {
console.error("Error connecting to MySQL:", err);
return;
}
console.log("Connected to MySQL!");
});
```
3. Java:
- In Java, you can use JDBC (Java Database Connectivity) to connect to a MySQL database.
- Make sure you have the MySQL JDBC driver (Connector/J) in your project.
- Example:
```java
import java.sql.Connection;
import java.sql.DriverManager;
import java.sql.SQLException;
public class Main {
public static void main(String[] args) {
String url = "jdbc:mysql://localhost:3306/your_database";
String username = "your_username";
String password = "your_password";
try {
Connection conn = DriverManager.getConnection(url, username, password);
System.out.println("Connected to MySQL!");
} catch (SQLException e) {
System.err.println("Connection failed: " + e.getMessage());
}
}
}
```
Remember to replace `"your_username"`, `"your_password"`, and `"your_database"` with your actual database credentials. Once connected, you can execute queries and interact with your MySQL database.

Can Ms access be Link to MySQL online?
Hi,
Yes, it is possible to link Microsoft Access to a MySQL database hosted online.
To do this, you will need to set up an ODBC (Open Database Connectivity) data source for MySQL on your Windows computer, and then use Microsoft Access to connect to the data source.
Here are the general steps to follow:
Install the MySQL ODBC driver on your Windows computer. You can download the driver from the MySQL website.
Set up a new ODBC data source for MySQL using the Windows ODBC Data Source Administrator tool. To do this, open the tool from the Control Panel, navigate to the System DSN tab, and click the "Add" button. Select the MySQL ODBC driver from the list and follow the prompts to configure the data source, providing the necessary details such as the MySQL server address, port, username, and password.
In Microsoft Access, open the database that you want to link to the MySQL database.
From the "External Data" tab, select "ODBC Database" to open the "Get External Data - ODBC Database" wizard.
In the wizard, select the option to link to the data source by creating a linked table.
In the next step of the wizard, select the ODBC data source that you created in step 2.
Follow the prompts to specify the tables or views that you want to link to in the MySQL database.
Once you have completed these steps, you should be able to access the MySQL data through the linked tables in your Microsoft Access database.
Note that the performance of the linked tables may depend on the speed and reliability of your internet connection to the MySQL server, as well as the complexity and size of the data being accessed.
@@RaghavPalthanks so much for your kind response.
Again with the above video, can I link Phpmyadmin with MS access as front end. With ODBC connector.
Or are there other approach.
I tried it, it work very fine, though slow. But I want annual subscription payment. I don't know how to go about it
when i hit go it just refreshes the page
Ahsan, it may be down or some backend issue. You can try other options. Here are some options for creating free MySQL databases online that you can use for testing and demo purposes:
1. DB Fiddle: An online SQL database playground where you can test, debug, and share SQL snippets. It's great for experimenting with queries
2. OneCompiler's MySQL Online Editor: Write, compile, debug, run, and test MySQL queries online using OneCompiler
3. db4free.net: Create an account for free and test your applications. It's useful for ensuring your apps work after a MySQL version update and for learning new features

After create and try to login phpmy admin is show #1040- To many connections
Step 1: Understand the error message
The error message `#1040 - Too many connections` indicates that the maximum number of allowed connections to the MySQL database has been reached. This is a common issue when using a free database service, as they often have limitations on the number of concurrent connections.
Step 2: Check the connection limit
Visit the www.freesqldatabase.com/freemysqldatabase/ website and check the documentation or FAQs to see what the maximum allowed connections are for their free plan. This will give you an idea of how many connections you're allowed to have.
Step 3: Check your application's connection usage
Review your PHP application's code to see how many connections it's making to the database. Are you using persistent connections or are you closing connections properly after each query? Make sure your application is not leaving connections open, which can contribute to reaching the maximum allowed connections.
Step 4: Check for idle connections
It's possible that there are idle connections to the database that are not being used. You can try to identify and close these idle connections. You can do this by running a query in phpMyAdmin:
```sql
SHOW PROCESSLIST;
```
This will show you a list of all current connections to the database. Look for connections that have been idle for a long time and consider closing them.
Step 5: Consider upgrading your plan
If you're consistently reaching the maximum allowed connections, it might be time to consider upgrading to a paid plan that offers more connections or looking into alternative database services that offer more generous connection limits.
