【问题描述】:
在我的 GridView 中,我有一个员工列表。当我单击删除链接时,我正在调用从两个表中删除信息的存储过程。无论如何,第一张桌子都可以正常工作。第二个表也可以正常工作,但是,如果最初有超过 4 行与给定 EmployeeID 对应的数据,即使所有数据都按预期删除,它也会返回错误。如果我删除第二个删除语句并按原样保留 Cities 表,我不会收到任何错误,因此它一定与该命令有关。由于第二个表中的数据没有出现在 GridView 中,我不确定为什么会这样。有什么想法吗?
存储过程:删除用户
DELETE FROM Users WHERE ID=@ID
DELETE FROM Cities WHERE ID=@ID
ASPX
<asp:GridView ID="GridView1" runat="server" AutoGenerateColumns="False"
DataKeyNames="ID" DataSourceID="SqlDS1" AllowSorting="True">
<Columns>
<asp:CommandField ShowDeleteButton="True" />
<asp:BoundField DataField="ID" HeaderText="ID"
SortExpression="ID" ReadOnly="True" />
<asp:BoundField DataField="Username" HeaderText="Username"
SortExpression="Username" ReadOnly="True" />
</Columns>
</asp:GridView>
<asp:SqlDataSource ID="SqlDS1" runat="server"
ConnectionString="<%$ ConnectionStrings:ConnectionString %>"
SelectCommandType="StoredProcedure" SelectCommand="SelectUser"
DeleteCommandType="StoredProcedure" DeleteCommand="DeleteUser">
<SelectParameters>
<asp:Parameter Name="ID" Type="String" DefaultValue="All" />
</SelectParameters>
<DeleteParameters>
<asp:Parameter Name="ID" Type="String"></asp:Parameter>
</DeleteParameters>
</asp:SqlDataSource>

另外,我应该提一下,如果我直接在 SQL 中运行 DeleteUser 存储过程,则会按预期从两个表中删除所有内容,并且不会返回任何错误。
