PreparedStatement使用方法JDBC存储过程调用的代码实例是本文我们主要要介绍的内容,接下来就让我们一起来了解一下下面的代码实例吧。
代码实例如下:
- package datebase;
- import java.sql.*;
- public class mypreparedstatement {
- private final String db_driver="com.microsoft.sqlserver.jdbc.SQLServerDriver";
- private final String url = "jdbc:sqlserver://localhost:1433;DatabaseName=ZC_NmSoft";
- public mypreparedstatement()
- {
- }
- public void query() throws SQLException{
- Connection conn = this.getconnection();
- //*********************************************查询********************
- String strsql = "select * from ZC_Attendanceregister where AR_ID = ?";
- PreparedStatement pstmtq = conn.prepareStatement(strsql);
- pstmtq.setInt(1, 587);
- ResultSet rs = pstmtq.executeQuery();
- while(rs.next()){
- String fname = rs.getString("AR_AdmissionID");
- System.out.println("the fname is " + fname);
- }
- //************************************************删除******************
- String strsqld= "delete from ZC_Attendanceregister where AR_ID = ?";
- PreparedStatement pstmtd = conn.prepareStatement(strsqld);
- pstmtd.setInt(1, 587);
- int dd = pstmtd.executeUpdate();
- //***********************************************添加*******************
- String strsqladd = "insert into ZC_Attendanceregister(AR_RegistrationDate,AR_AdmissionID,AR_Attendance,AR_Notes,AR_Mealssettlement) values(?,?,?,?,?)";
- PreparedStatement pstmta = conn.prepareStatement(strsqladd);
- pstmta.setString(1, "2010-07-26");
- pstmta.setString(2, "260");
- pstmta.setString(3, "出勤");
- pstmta.setString(4, "备注");
- pstmta.setString(5, "应该缴费");
- int add = pstmta.executeUpdate();
- rs.close();
- pstmta.close();
- conn.close();
- }
- private Connection getconnection() throws SQLException{
- // class.
- Connection conn = null;
- try {
- Class.forName(db_driver);
- conn = DriverManager.getConnection(url,"sa","sa");
- }
- catch (ClassNotFoundException ex) {}
- return conn;
- }
- //main 测试
- public static void main(String[] args) throws SQLException {
- mypreparedstatement jdbctest1 = new mypreparedstatement();
- jdbctest1.query();
- }
- }
以上就是PreparedStatement使用之JDBC存储过程调用的代码实例,本文我们就介绍到这里了,希望本次的介绍能够对您有所收获!
