JAVA如何插入MySql的datetime类型的简单的例子
过去我一直都是把时期做为字符类型来处理,汗,最近项目需要比较时间就没辙了，特意查了下资料才明白java可以直接插入日期型的数据，孤陋寡闻！import java.sql.Connection;
import java.sql.DriverManager;
import java.sql.PreparedStatement;
import java.sql.Timestamp;

public class DataBaseTest {
private Connection conn;
PreparedStatement pStmt=null;
private void test(){
try{
Class.forName("com.mysql.jdbc.Driver").newInstance();
String url ="jdbc:mysql://localhost:3306/rhino?user=root&password=&useUnicode=true&characterEncoding=UTF-8";
Connection conn= DriverManager.getConnection(url);
System.out.println("connect to database successfully!");
pStmt=conn.prepareStatement("INSERT INTO RH_ENTRY"+
"(id,allow_comments,category_id,comment_count,content,create_on,name,status)"+
"values(?,?,?,?,?,?,?,?)");
conn.setAutoCommit(false);
java.util.Date date=new java.util.Date();
Timestamp tt=new Timestamp(date.getTime());
pStmt.setInt(1,1);
pStmt.setInt(2,1);
pStmt.setInt(3,1);
pStmt.setInt(4,5);
pStmt.setString(5,"shit!!!!!");
pStmt.setTimestamp(6,tt);
pStmt.setString(7,"jordan");
pStmt.setInt(8,1);
int j=pStmt.executeUpdate();
conn.commit();
if(j!=0)
System.out.println("ok");
}catch(Exception e){
try{
conn.rollback();
}catch(Exception e1){
e1.printStackTrace(System.out);
}
e.printStackTrace();
}finally{
try{
pStmt.close();
}catch(Exception e){
e.printStackTrace();
}
}
}
public static void main(String args[]){
DataBaseTest dt=new DataBaseTest();
dt.test();
}
}
