Insert into table in Java

Description

The following code shows how to insert into table.

Example


import java.sql.Connection;
import java.sql.DriverManager;
import java.sql.PreparedStatement;
import java.sql.ResultSet;
import java.sql.ResultSetMetaData;
import java.sql.Statement;
//from  w ww . jav  a2  s .co m
public class Main {
  public static void main(String[] args) throws Exception {
    Connection conn = getConnection();
    Statement st = conn.createStatement();

    st.executeUpdate("create table survey (id int, myDate TIMESTAMP );");
    
    String INSERT_RECORD = "insert into survey(id) values(?)";
    
    PreparedStatement pstmt = conn.prepareStatement(INSERT_RECORD);
    pstmt.setString(1, "1");
    pstmt.executeUpdate();

    ResultSet rs = st.executeQuery("SELECT * FROM survey");
    outputResultSet(rs);

    
    pstmt.setString(1, "2");
    pstmt.executeUpdate();

    rs = st.executeQuery("SELECT * FROM survey");
    outputResultSet(rs);

    
    rs.close();
    st.close();
    conn.close();
  }
  private static void outputResultSet(ResultSet rs) throws Exception {
    ResultSetMetaData rsMetaData = rs.getMetaData();
    int numberOfColumns = rsMetaData.getColumnCount();
    for (int i = 1; i < numberOfColumns + 1; i++) {
      String columnName = rsMetaData.getColumnName(i);
      System.out.print(columnName + "   ");

    }
    System.out.println();
    System.out.println("----------------------");

    while (rs.next()) {
      for (int i = 1; i < numberOfColumns + 1; i++) {
        System.out.print(rs.getString(i) + "   ");
      }
      System.out.println();
    }

  }

  private static Connection getConnection() throws Exception {
    Class.forName("org.hsqldb.jdbcDriver");
    String url = "jdbc:hsqldb:mem:data/tutorial";

    return DriverManager.getConnection(url, "sa", "");
  }
}

The code above generates the following result.
