小编use*_*851的帖子

我创建了表值参数,如下所示:

CREATE TYPE dbo.ss AS TABLE(ss1 NVARCHAR(5));

然后我写了这样的存储过程:

ALTER PROCEDURE [dbo].[T_TransactionSummary] 
 @locations dbo.ss readonly
as
begin
...............
.............
AND (Location_tbl.Locid IN (@locations))

执行此操作时我收到错误:

必须声明标量变量"@locations".

我的存储过程有什么问题

我有一个这样的存储过程:

ALTER PROCEDURE [dbo].[T_TransactionSummary]  
 @locations nvarchar
AS
    BEGIN 
..............
.............
AND (Location_tbl.Locid IN (@locations))

我的locid字段是整数这个locid来自我的listbox.if我选择一个项目1 locid将来.如果我选​​择2项目2 locid将来..我有一个ListBox填充@locations参数(一个整数),我把这个列表框值这样

cnt = LSTlocations.SelectedItems.Count
 Dim list As New List(Of Integer)
        Dim locid As Integer
        If cnt > 0 Then
            For i = 0 To cnt - 1
                Dim locationanme As String = LSTlocations.SelectedItems(i).ToString
                locid = RecordID("Locid", "Location_tbl", "LocName", locationanme)
                list.Add(locid)
            Next
End If
 Dim da As New SqlDataAdapter
        Dim ds As New DataSet
        Dim cmd23 As New SqlCommand("T_TransactionSummary", con.connect)
        cmd23.CommandType = CommandType.StoredProcedure
        cmd23.Parameters.Add("@locations", SqlDbType.Int).Value …
