Data query and operation in Jaybird JDBC Driver framework
The JAYBIRD JDBC Driver framework is a Java driver used to connect and operate the Firebird database.It provides a simple and efficient way to perform data query and operation, integrates Java and Firebird database.This article will introduce the basic methods of data query and operation in the Jaybird JDBC Driver framework, and provide some Java code examples.
1. Installation and configuration Jaybird JDBC Driver
First, you need to download and install Jaybird JDBC Driver.You can download the latest version of Driver from the official website.After the installation is complete, add JAYBIRD's jar file to the class path of the Java project.
Next, you need to configure the database connection information in the Java code.You can use the following code example to create a database connection object:
import java.sql.Connection;
import java.sql.DriverManager;
import java.sql.SQLException;
public class DatabaseConnection {
private static Connection connection;
public static Connection getConnection() throws SQLException {
if (connection == null || connection.isClosed()) {
String url = "jdbc:firebirdsql://localhost:3050/your_database_name";
String user = "your_username";
String password = "your_password";
connection = DriverManager.getConnection(url, user, password);
}
return connection;
}
}
2. Data query operation
In the Jaybird JDBC Driver framework, the Java standard SQL statement can be used to perform data query operations.The following is a simple example, showing how to query the data in the database:
import java.sql.Connection;
import java.sql.ResultSet;
import java.sql.SQLException;
import java.sql.Statement;
public class QueryExample {
public static void main(String[] args) {
try {
Connection connection = DatabaseConnection.getConnection();
Statement statement = connection.createStatement();
String sql = "SELECT * FROM your_table_name";
ResultSet resultSet = statement.executeQuery(sql);
while (resultSet.next()) {
int id = resultSet.getInt("id");
String name = resultSet.getString("name");
// Print the query results
System.out.println("id: " + id + ", name: " + name);
}
resultSet.close();
statement.close();
connection.close();
} catch (SQLException e) {
e.printStackTrace();
}
}
}
3. Data operation
In the Jaybird JDBC Driver framework, the standard SQL statement of Java can be used to perform data operations, such as inserting, updating, and deleting data.The following is a simple example that shows how to insert a new data into the database:
import java.sql.Connection;
import java.sql.SQLException;
import java.sql.Statement;
public class DataOperationExample {
public static void main(String[] args) {
try {
Connection connection = DatabaseConnection.getConnection();
Statement statement = connection.createStatement();
String sql = "INSERT INTO your_table_name (column1, column2) VALUES ('value1', 'value2')";
int rowsAffected = statement.executeUpdate(sql);
System.out.println ("Insert" + ROWSAFFECTD + "line data.");
statement.close();
connection.close();
} catch (SQLException e) {
e.printStackTrace();
}
}
}
Through the above examples, we show the basic methods and code examples of data query and operation in the Jaybird JDBC Driver framework.Using Jaybird JDBC Driver, you can easily integrate with Firebird database and use Java to perform database operations.
