asp.net - 如何将下拉的串联值作为参数传递给存储的过程

Question

我有一个下拉列表，其中的值是从表的两列连接起来的，现在我将使用该下拉列表的值作为另一个存储过程的参数，这可能吗？我将如何做到这一点？

这是我的代码

CREATE PROCEDURE [dbo].[Reassign]
   @recordumber int
   @employeeName
AS
BEGIN
    UPDATE QR
    SET QR.QAMemberID = @QAMemberID
    FROM Roster AS QR
    INNER JOIN TeamMaster S TM 
       ON QR.QAMemberID = TM.QAMemberID
    WHERE QR.recordNumber = @recordumber
      and qr.firstname, qr.lastname = @employeeName
END

而且qr.firstname，qr.lastname = @employeeName我知道最后一段代码是错误的......我怎样才能以正确的方式做到这一点？谢谢...

Answer 1

不要在代码中将值连接在一起，而是使用参数 forfirstName和参数 for lastName，如下所示：

CREATE PROCEDURE [dbo].[Reassign]
    @recordumber int,
    @firstName,
    @lastName
AS
BEGIN
    UPDATE QR
    SET QR.QAMemberID = @QAMemberID
    FROM Roster AS QR
    INNER JOIN TeamMaster S TM 
        ON QR.QAMemberID = TM.QAMemberID
    WHERE QR.recordNumber = @recordumber
        and qr.firstname = @firstName, qr.lastname = @lastName
END

Answer 2

要使用下拉列表中的值，您可以在后面的代码中使用它

 if (myDropDown.SelectedIndex != 0) 
 {
     var myData = myDropDown.SelectedValue;

     // access Sproc and you can then pass myData


 }

Answer 3

qr.firstname + ' ' + qr.lastname = @employeeName如果您将这些字段与空格连接起来，则可以使用。

...
  and qr.firstname + ' ' + qr.lastname = @employeeName
...

但最好将两个参数传递到过程中：

CREATE PROCEDURE [dbo].[Reassign]
   @recordumber int
   @firstname,
   @lastname
AS
...
  and qr.firstname = @firstname and qr.lastname = @lastname
...
