如何在 java 中插入日期和时间
How to insert date and time in java
我正在使用 JDBC oracle database.And 在 Netbeans IDE 中做一个 java 项目，我需要将日期和时间插入数据库，这是格式为 11/16/2013 10:30。
我在下面附上了我的代码。
在 DBConnector
中插入代码
public void insert(String id, String uid, String vmid, String ttid, String faid, String taid, String fdate, String tdate, String onbooking, String msbooking, String bcreated)
throws SQLException {
Statement stmt = null;
String query = "Insert into DMUSER.CAB2("
+ "ID,"
+ "USER_ID,"
+ "VEHICLE_MODEL_ID,"
+ "TRAVEL_TYPE_ID,"
+ "FROM_AREA_ID,"
+ "TO_AREA_ID,"
+ "FROM_DATE,"
+ "TO_DATE,"
+ "ONLINE_BOOKING,"
+ "MOBILE_SITE_BOOKING,"
+ "BOOKING_CREATED"
+ ") values ("
+ id + ","
+ uid + ","
+ vmid + ","
+ ttid + ","
+ faid + ","
+ taid + ","
+ fdate + ","
+ tdate + ","
+ onbooking + ","
+ msbooking + ","
+ bcreated + ""
+ ")";
按钮点击事件
private void btn_insertActionPerformed(java.awt.event.ActionEvent evt) {
txt_id.setText("132536");
txt_user_id.setText("16");
txt_vechile_mdl_id.setText("28");
txt_from_area_id.setText("58");
txt_to_area_id.setText("1063");
txt_frm_date.setText("11/16/2013 9:30");
txt_to_date.setText("NULL");
txt_booking_created.setText("11/16/2013 9:30");
txt_travel_type_id.setText("2");
txt_mobile_site_booking.setText("0");
txt_online_booking.setText("1");
}
private void btn_predictionActionPerformed(java.awt.event.ActionEvent evt) {
try {
String id = txt_id.getText();
String uid = txt_user_id.getText();
String vmid = txt_vechile_mdl_id.getText();
String ttid = txt_travel_type_id.getText();
String faid = txt_from_area_id.getText();
String fdate = txt_frm_date.getText();
String tdate = txt_to_date.getText();
String onbooking = txt_online_booking.getText();
String msbooking = txt_mobile_site_booking.getText();
String bcreated = txt_booking_created.getText();
String taid = txt_to_area_id.getText();
DB_Connector con = new DB_Connector();
try {
con.insert(id, uid, vmid, ttid, faid, taid, fdate, tdate, onbooking, msbooking, bcreated);
} catch (SQLException ex) {
Logger.getLogger(CabCancellationUI.class.getName()).log(Level.SEVERE, null, ex);
}
} 赶上（异常前）{
}
}
这里的问题是，在数据库中日期列是 VARCHAR 数据类型，所以我如何插入这个 11/16/2013 10:30进入 database.Please 帮我解决这个问题。

问题不是你想的那样。异常是抱怨错误的 sql-插入数据的语法。
您需要更正插入方法中的查询字符串。此外，您接受的每个 table 列都是字符串，这似乎是不正确的。考虑 table 的每一列的正确数据类型，比如 ID 应该是数字，而不是 varchar 等。
如果每个参数都是字符串类型，那么正确的代码必须在查询字符串中的参数前后各处添加'，如下所示：
String query = "Insert into DMUSER.CAB2("
+ "ID,"
+ "USER_ID,"
+ "VEHICLE_MODEL_ID,"
+ "TRAVEL_TYPE_ID,"
+ "FROM_AREA_ID,"
+ "TO_AREA_ID,"
+ "FROM_DATE,"
+ "TO_DATE,"
+ "ONLINE_BOOKING,"
+ "MOBILE_SITE_BOOKING,"
+ "BOOKING_CREATED"
+ ") values ("
+ "'"+ id + "',"
+ "'" + uid + "',"
+ "'" + vmid + "',"
+ "'" + ttid + "',"
+ "'" + faid + "',"
+ "'" + taid + "',"
+ "'" + fdate + "',"
+ "'" + tdate + "',"
+ "'" + onbooking + "',"
+ "'"+ msbooking + "',"
+ "'"+bcreated + "'"
+ ")";
最后，这是一个糟糕的代码。你应该考虑使用 PreparedStatement.
