使用PreparedStatement操作Oracle数据库
使用PreparedStatement操作Oracle数据库: 1.定义预处理SQL语句;2.为每一个“?”设置对应的值;
3.使用PreparedStatement操作数据库。
TestPreparedStmt.java:
view plaincopy to clipboardprint?
[*]import java.sql.*;
[*]
[*]
[*]public class TestPreparedStmt {
[*]
[*] public static void main(String[] args) {
[*] Connection conn = null;
[*] PreparedStatement pstmt = null;
[*] String sql = null;
[*] int id = 0;
[*] String name = null;
[*] if (args.length != 2) {
[*] System.exit(-1);
[*] } else {
[*] id = Integer.parseInt(args);
[*] name = args;
[*] }
[*] try {
[*] Class.forName("oracle.jdbc.driver.OracleDriver");
[*] conn = DriverManager.getConnection("jdbc:oracle:thin:@127.0.0.1:1521:mgc", "system", "admin");
[*] sql = "Insert INTO member(id,name) VALUES(?,?)";
[*] pstmt = conn.prepareStatement(sql);
[*] pstmt.setInt(1, id);
[*] pstmt.setString(2, name);
[*] pstmt.executeUpdate();
[*] } catch (ClassNotFoundException e) {
[*] e.printStackTrace();
[*] } catch (SQLException e) {
[*] e.printStackTrace();
[*] } finally {
[*] try {
[*] if (pstmt != null) {
[*] pstmt.close();
[*] pstmt = null;
[*] }
[*] if (conn != null) {
[*] conn.close();
[*] conn = null;
[*] }
[*] } catch (SQLException e) {
[*] e.printStackTrace();
[*] }
[*] }
[*] }
[*]
[*]}
