Question

我有一个GridView。如果我将其复制并粘贴到SQL Server Management Studio中，我的代码中的SelectCommand将起作用。它执行得很好。

如果我运行该页面并单击任何行的编辑，则会收到错误：

“关键字'IS'附近的语法不正确。”

我试图了解使用SQL Server Profiler的情况。这是SelectCommand的样子以及SQL正在接收的内容......

来自supplies.ascx的SelectCommand

SELECT some stuff FROM here WHERE (this IS NULL) and (that=1) ORDER BY this DESC

SQL Server Profiler报告

SELECT some stuff FROM here (this IS NULL) and (that=1) ORDER BY this DESC

我没有在这里放任何代码，因为我不确定什么是相关的，并且不想用不必要的代码行加载帖子。请告诉我您希望看到的帮助。

请求下面的代码。我没有放入GridView中的所有内容......它非常大。如果需要，我可以更新。

<asp:GridView ID="GridView1" runat="server" AutoGenerateColumns="False" DataKeyNames="fldSupReqID"

这就是SQL Server Profiler捕获的内容......

SELECT tblSupplyRequests.fldSupReqID, tblSupplyRequests.fldOrderToShipDate, tblSupplyRequests.fldBID AS BID, tblMerchantIDs.fldMerchantID AS MerchantID, salescontactinfo.sname_of_business AS [Merchant Name], salescontactinfo.scontactname1 AS Contact, salescontactinfo.scontactn1phone1 AS Phone, tblSupplyRequests.fldRequestDate, tblSupplyRequests.fldAddedByUser AS RequestedBy, INVtblManufacturers.fldManufacturerName AS [Term Manuf], INVtblInventoryItems_1.fldItemName AS [Term Model], INVtblInventoryTypes.fldInventoryTypename AS [Item Type], tblSupplyRequests.fldNumItemsRequested AS [Num Items], tblSupplyRequests.fldPaperItemID, tblSupplyRequests.fldPerItemCost, INVtblInventoryItems.fldMiscDesc, tblSupplyRequests.fldPersonCalling, tblSupplyRequests.fldTitlePersonCalling, tblSupplyRequests.fldNotes, salescontactinfo.sstate, tblSupplyRequests.fldManufacturerID, tblSupplyRequests.fldItemID, tblSupplyRequests.fldStamp, tblSupplyRequests.fldOrderToShipDate AS Expr1, tblSupplyRequests.fldOrderToShipBy FROM INVtblInventoryItems INNER JOIN tblSupplyRequests INNER JOIN salescontactinfo ON tblSupplyRequests.fldBID = salescontactinfo.sbusinessid LEFT OUTER JOIN tblMerchantIDs ON salescontactinfo.sbusinessid = tblMerchantIDs.fldBID LEFT OUTER JOIN INVtblManufacturers ON tblSupplyRequests.fldManufacturerID = INVtblManufacturers.fldManufacturerID ON INVtblInventoryItems.fldItemID = tblSupplyRequests.fldPaperItemID LEFT OUTER JOIN INVtblInventoryTypes ON tblSupplyRequests.fldInventoryTypeID = INVtblInventoryTypes.fldInventoryTypeID LEFT OUTER JOIN INVtblInventoryItems AS INVtblInventoryItems_1 ON tblSupplyRequests.fldItemID = INVtblInventoryItems_1.fldItemID  (tblSupplyRequests.fldOrderToShipDate IS NULL) AND (tblMerchantIDs.fldMIDStatusID=1) ORDER BY tblSupplyRequests.fldRequestDate DESC

我不想这么说，但可能只是因为ASP.NET在一行之前的所有嵌套INNER JOIN都错误地解析了查询。我想知道格式化SQL是否会有所帮助？ neatly formatting your SQL statements在线有一个非常酷的工具。

以下是SQLDataSource的格式化版本：

<asp:SqlDataSource ID="SqlDataSource1" runat="server" ConnectionString="<%$ ConnectionStrings:myConnectionString %>"
    DeleteCommand=" DELETE FROM [tblSupplyRequests] 
                    WHERE  [fldSupReqID] = @fldSupReqID"
    InsertCommand=" INSERT INTO [tblSupplyRequests] ([fldManufacturerID],[fldItemID],[fldFeeTypeID],[fldRequestDate],[fldStamp],[fldAddedByUser],[fldBID]) 
                    VALUES (@fldManufacturerID,@fldItemID,@fldFeeTypeID,@fldRequestDate,@fldStamp,@fldAddedByUser,@fldBID)"       
    ProviderName="<%$ ConnectionStrings:myConnectionString.ProviderName %>" 
    SelectCommand=" SELECT tblsupplyrequests.fldsupreqid, 
                           tblsupplyrequests.fldordertoshipdate,

注意：如果SQLDataSource中的查询变得复杂，您可能需要考虑将此逻辑移动到类/数据访问层以便将来维护。话虽如此，我明白，有时你会被时间紧迫的东西=）祝你好运！
