[英]syntax in sqldatasource selectcommand
My SqlDataSource selectcommand is dynamically changed by the String.Format functionality of the Eval one-way databinding syntax. 我的SqlDataSource selectcommand由Eval单向数据绑定语法的String.Format功能动态更改。 It works ok.
可以。 However I need to put together two columns values with a space in the middle (ItemType + '" "' + ItemDescription As ItemInfo) but I can't get the syntax correct as I get the message: "The server tag is not well formed"
但是,我需要将两列值放在一起,中间有一个空格(ItemType +'“”'+ ItemDescription As ItemInfo),但是我收到消息后语法不正确:“服务器标记格式不正确”
Can you help? 你能帮我吗? Many thanks
非常感谢
<asp:SqlDataSource ID="SqlDataSource1" runat="server" ConnectionString="<%$ ConnectionStrings:conn %>" SelectCommand='<%# Eval("TypeID", "SELECT ItemID, ItemType, ItemType + '" "' + ItemDescription As ItemInfo WHERE ItemType = {0}")%>'> </asp:SqlDataSource>
It could be a more general issue with " 可能是“
<asp:SqlDataSource ID="SqlDataSource1" runat="server"
ConnectionString="<%$ConnectionStrings:conn %>"
SelectCommand='<%# Eval("TypeID", "SELECT ItemID, ItemType, ItemType + "\" \"" + ItemDescription As ItemInfo WHERE ItemType = {0}")%>'>
</asp:SqlDataSource>
HiI resolved the issue in this way (as advised in How to use Single Quotes in Eval Format String ) HiI以这种方式解决了该问题(如如何在Eval格式字符串中使用单引号中所述 )
In items.aspx.vb 在items.aspx.vb中
Protected Const SqlQuery As String = "SELECT ItemID, ItemType, ItemType + " + "' '" + " ItemDescription As ItemInfo WHERE ItemType = {0}"
In items.aspx 在items.aspx中
<asp:SqlDataSource ID="SqlDataSource1" runat="server" ConnectionString="<%$ ConnectionStrings:conn %>" SelectCommand='<%# Eval("TypeID", SQLQuery)%>'> </asp:SqlDataSource>
Many thanks 非常感谢
