JDBC Batch Execution In Java Using CallableStatement

Chapter: JDBC Last Updated: 26-06-2016 15:07:46 UTC

Program:

            /* ............... START ............... */
                
import java.sql.CallableStatement;
import java.sql.Connection;
import java.sql.DriverManager;
import java.sql.SQLException;

public class JavaJDBCBatchExecution {

	public static void main(String a[]) {

		Connection con = null;
		CallableStatement callSt = null;
		try {
			Class.forName("oracle.jdbc.driver.OracleDriver");
			con = DriverManager.getConnection("jdbc:oracle:thin:@<hostname>:"
					+ "<port num>:<DB name>", "user", "password");
			callSt = con.prepareCall("{call myprocedure(?,?)}");
			callSt.setInt(1, 200);
			callSt.setDouble(2, 3000);
			callSt.addBatch();
			callSt.setInt(1, 130);
			callSt.setDouble(2, 2000);
			callSt.addBatch();
			int[] updateCounts = callSt.executeBatch();
		} catch (ClassNotFoundException e) {
			// TODO Auto-generated catch block
			e.printStackTrace();
		} catch (SQLException e) {
			// TODO Auto-generated catch block
			e.printStackTrace();
		} finally {
			try {
				if (callSt != null)
					callSt.close();
				if (con != null)
					con.close();
			} catch (Exception ex) {
			}
		}
	}
}
                /* ............... END ............... */
        

Notes:

  • Batch execution is done using addBatch() method and executeBatch() method.
