How Do You Update an Existing Record Using PreparedStatement
The following sections show how to update an existing record of a table using a PreparedStatement object. How It Works
The following example creates a PreparedStatement object to update an existing record of the dept table (this program updates department locations for a given department number). The example uses a SQL UPDATE statement to update data for a table. Solution
Here s the solution: import java.util.*; import java.io.*; import java.sql.*; import jcb.util.DatabaseUtil; import jcb.db.VeryBasicConnectionManager; public class Update_Records_Using_PreparedStatement { CHAPTER 12 WORKING WITH THE PREPAREDSTATEMENT
public static void main(String[] args) { String dbVendor = args[0]; // { "mysql", "oracle" } int deptNumber = Integer.parseInt(args[1]); String deptLocation = args[2]; Connection conn = null; PreparedStatement pstmt = null; try { System.out.println("--Update_Records_... begin--"); conn = VeryBasicConnectionManager.getConnection(dbVendor); System.out.println("conn="+conn); System.out.println("deptNumber= "+ deptNumber); System.out.println("deptLocation= "+ deptLocation); // prepare query String query = "update dept set DEPT_LOC pstmt = conn.prepareStatement(query); // pstmt.setString(1, deptLocation); // pstmt.setInt(2, deptNumber); // pstmt.executeUpdate(); // System.out.println("--Update_Records_... } catch(Exception e){ e.printStackTrace(); System.exit(1); } finally { // release database resources DatabaseUtil.close(pstmt); DatabaseUtil.close(conn); } } } = where DEPT_NUM = "; create a statement set input parameter 1 set input parameter 2 execute update statement end--");
