JDBC Insert Statement
Add a row to a existing table using insert statement in JDBC. The
tutorial illustrates an example from JDBC Insert Statement. In this program, the
code include a class Jdbc Insert Statement. Inside this class we have a
list of method that help you to insert the new values to the existing
table as given below - Loading a driver by calling a class.forName(
),that accept driver class as parameter. The
DriverManager.getConnection ( ) returns you a connection object, which
built a connection between url and database. The connection object calls createStatement
( ),that returns you a sql object. This object send and execute sql
statements in database. To add a rows in an existing table, we use
INSERT statement. executeUpdate ( ) -
This method returns you the number of rows added and modified in a
table. The interface statement object ,st,executes the INSERT
statement using execute Update ( ).The executeQuery ( ) return you
the retrieved record set from a table using select statement Finally the
print ln print no, name from the table. Incase there is an exception in try block, the
catch block caught and handle the exception JdbcInsertStatement.java
import java.sql.*;
public class JdbcInsertStatement {
public static void main(String args[]) {
Connection con = null;
Statement st = null;
ResultSet rs = null;
String url = "jdbc:mysql://localhost:3306/";
String db = "komal";
String driver = "com.mysql.jdbc.Driver";
String user = "root";
String pass = "root";
try {
Class.forName(driver);
con = DriverManager.getConnection(url + db, user, pass);
con.setAutoCommit(false);// Disables auto-commit.
st = con.createStatement();
st.executeUpdate("INSERT INTO stu VALUES('1','Komal')");
st.executeUpdate("INSERT INTO stu VALUES('2','Ajay')");
st.executeUpdate("INSERT INTO stu VALUES('3','Santosh')");
st.executeUpdate("INSERT INTO stu VALUES('4','Girish')");
st.executeUpdate("INSERT INTO stu VALUES('5','Rakesh')");
st.executeBatch();
String sql = "select * from stu";
rs = st.executeQuery(sql);
System.out.println("No \tName");
while (rs.next()) {
System.out.print(rs.getString(1) + " \t");
System.out.println(rs.getString(2));
}
rs.close();
st.close();
con.close();
} catch (Exception e) {
e.printStackTrace();
}
}
