如何更改多个房间的房间状态？ [英] How to change room status of multiple rooms?

问题描述

我使用下面的代码来更改房间状态。它工作正常，因为直到那时我只需更改单人房间状态。

I am using code like below to change room status. It was working fine because till that time i had to change only single room status.

String sqlr = "update roominformation set status = '0' where roomno = '" + txt_roomno.Text + "'";
new OleDbCommand(sqlr, sr, trans).ExecuteNonQuery();

现在我在单个文本框（txt_roomno）中有多个房间，如Single-101，Single-102，Single-103。在此之前，我在文本框中只有一个房间，如Single-101，所以更新时没有问题。



我现在的问题是如何更改单个文本框中的多个房间号码的状态。



这将是第一个更改Single-101的状态，然后是Single-102，在Single-103之后。



我不知道如何完成这项任务..



请帮助。

Now i have multiple rooms in the single text box (txt_roomno) like Single-101,Single-102,Single-103. Before this i have only one room in the text box like Single-101,so there is no problem while updating this.

My Question is now how can i change the status of multiple room numbers from single text box.

It will be like First change the status of Single-101, then Single-102, after that Single-103.

I dont know how to achieve this task..

Please help.

推荐答案

以这种方式实现：

implement this way:

string text = txt_roomno.Text;
string[] arrRoomNos = text.Split(',');

string roomNosCSV = string.Empty;
foreach (string room in arrRoomNos)
{
    if (roomNosCSV != string.Empty)
        roomNosCSV += ",";

    roomNosCSV += "'" + room.Trim() + "'";
}

String sqlr = "update roominformation set status = '0' where roomno in (" + roomNosCSV + ")";
new OleDbCommand(sqlr, sr, trans).ExecuteNonQuery();

Hello Harpreet，



以逗号格式分隔的单个变量中的多个房间号。

例如

Hello Harpreet,

Take the multiple room number in single variable separated by comma format.
E.g.

String txt_roomno.Text= 'Single-101,Single-102,Single-103' ;

编写你的SQL查询如下

And write your SQL query as below

String sqlr = "update roominformation set status ='0' where roomno in '" + txt_roomno.Text + "'";
