Steps to Execute SQL Query with Pagination in JDBC

Java Program to Execute a SQL Query with Pagination in JDBC

Below are the steps to execute a SQL query with pagination in JDBC.

Step 1: Establish a Database Connection

Connection connection = DriverManager.getConnection
  ("jdbc:mysql://localhost:3306/your_database", "username", "password");

Step 2: Prepare the SQL Query

String sql = "SELECT * FROM your_table LIMIT ? OFFSET ?";

Step 3: Define Pagination Parameters

int pageSize = 10; // Number of records per page
int pageNumber = 2; // Desired page number
int offset = (pageNumber - 1) * pageSize;

Step 4: Create a PreparedStatement

PreparedStatement preparedStatement = connection.prepareStatement(sql);
preparedStatement.setInt(1, pageSize);
preparedStatement.setInt(2, offset);

Step 5: Execute the Query

ResultSet resultSet = preparedStatement.executeQuery();

Step 6: Process the ResultSet

while (resultSet.next()) {
    // data retrieved from the result set
    // Example:
    // int id = resultSet.getInt("id");
    // String name = resultSet.getString("name");
    // Process data as needed
}

Step 7: Close Resources

resultSet.close();
preparedStatement.close();
connection.close();

This is how we execute a SQL query with pagination using JDBC.

How to Execute a SQL Query with Pagination in JDBC?

To execute a SQL query with pagination in JDBC (Java Database Connectivity), normally we use SQL syntax to limit the number of rows returned and then iterate through the results as per the need. We often use SQL’s LIMIT and OFFSET clauses to execute page SQL queries in JDBC.
