Java ResultSet CONCUR_UPDATABLE

Syntax

ResultSet.CONCUR_UPDATABLE has the following syntax.

static final int CONCUR_UPDATABLE

Example

In the following code shows how to use ResultSet.CONCUR_UPDATABLE field.


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

    st.executeUpdate("create table survey (id int,name varchar(30));");
    st.executeUpdate("insert into survey (id,name ) values (1,'nameValue')");
    st.executeUpdate("insert into survey (id,name ) values (2,null)");
    st = conn.createStatement();
    ResultSet rs = st.executeQuery("SELECT * FROM survey");

    int rsConcurrency = rs.getConcurrency();
    if (rsConcurrency == java.sql.ResultSet.CONCUR_READ_ONLY) {
      System.out.println("java.sql.ResultSet.CONCUR_READ_ONLY");
    } else if (rsConcurrency == java.sql.ResultSet.CONCUR_UPDATABLE) {
      System.out.println("java.sql.ResultSet.CONCUR_UPDATABLE");
    } else {
      // it is an error

    }

    rs.close();
    st.close();
    conn.close();

  }

  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.
