Question

我发现将数据类型nvarchar转换为bigint时出现了数千个问题，但没有针对我的具体问题的解决方案。我有一个通用表DynamicArticle_ParameterResult，其中值字段可以包含所有内容（数字/文本）。

如果我根据连接（ArticleResultID = DAAR.ID）进行子查询，我会'错误地将数据类型nvarchar转换为bigint'：

SELECT        OSL.GroupName AS MAINGROUPNAME, DAAR.SalesLineID, DAAR.SalesID, DAAR.ID, spt.number + 1 AS SUBNO,   (SELECT        Value
                           FROM            DynamicArticle_ParameterResult AS DynamicArticle_ParameterResult_9
                           WHERE        (ArticleResultID = DAAR.ID) AND (Name = 'Panel_Dx')) AS Panel_dx,
                         (SELECT        Value
                           FROM            DynamicArticle_ParameterResult AS DynamicArticle_ParameterResult_8
                           WHERE        (ArticleResultID = DAAR.ID) AND (Name = 'Panel_Dy')) AS Panel_dy,
                         (SELECT        Value
                           FROM            DynamicArticle_ParameterResult AS DynamicArticle_ParameterResult_7
                           WHERE        (ArticleResultID = DAAR.ID) AND (Name = 'Panel_Dz')) AS Panel_dz,

                         (SELECT        Name
                           FROM            ProductManagerConfig.dbo.Colors
                           WHERE        (Id =
                                                         (SELECT        TOP (1) Value
                                                           FROM            DynamicArticle_ParameterResult
                                                           WHERE        (ArticleResultID = DAAR.ID) AND (Name = 'Panel_Color')))) AS COLORNAME, OSL.GroupName AS Soort, ST.LoadDay, ST.RouteNumber, ST.RouteOrderNumber, ST.SalesNumber, 
                     ST.ProductionNumber, Products.GroupName, Products.FullNameFROM            DynamicArticle_ArticleResult AS DAAR INNER JOIN
                     ProductManager_Products AS Products ON Products.ItemID = DAAR.ItemID INNER JOIN
                     SalesTable AS ST ON ST.Id = DAAR.SalesID INNER JOIN
                     OrderSalesLines AS OSL ON OSL.SalesLineID = Products.SalesLineID AND OSL.Depth = 0 INNER JOIN
                     SalesLines AS SL ON SL.Id = Products.SalesLineID INNER JOIN
                     master.dbo.spt_values AS spt ON spt.type = 'P' AND spt.number < SL.Quantity WHERE        (Products.Id IN (116994,116993)) AND (DAAR.Name = 'Panel' OR
                     DAAR.Name = 'KlassiekPaneel')

如果我在子查询中放置一个过滤器（（ArticleResultID IN（1075728,1075669）），它运行正常吗？

SELECT        OSL.GroupName AS MAINGROUPNAME, DAAR.SalesLineID, DAAR.SalesID, DAAR.ID, spt.number + 1 AS SUBNO,   (SELECT        Value FROM            DynamicArticle_ParameterResult AS DynamicArticle_ParameterResult_9
                           WHERE        (ArticleResultID IN(1075728,1075669)) AND (Name = 'Panel_Dx')) AS Panel_dx,
                         (SELECT        Value
                           FROM            DynamicArticle_ParameterResult AS DynamicArticle_ParameterResult_8
                           WHERE        (ArticleResultID IN(1075728,1075669)) AND (Name = 'Panel_Dy')) AS Panel_dy,
                         (SELECT        Value
                           FROM            DynamicArticle_ParameterResult AS DynamicArticle_ParameterResult_7
                           WHERE        (ArticleResultID IN(1075728,1075669)) AND (Name = 'Panel_Dz')) AS Panel_dz,

                         (SELECT        Name
                           FROM            ProductManagerConfig.dbo.Colors
                           WHERE        (Id =
                                                         (SELECT        TOP (1) Value
                                                           FROM      DynamicArticle_ParameterResult
                                                           WHERE        (ArticleResultID IN(1075728,1075669)) AND (Name = 'Panel_Color')))) AS COLORNAME, OSL.GroupName AS Soort, ST.LoadDay, ST.RouteNumber, ST.RouteOrderNumber, ST.SalesNumber, 
                     ST.ProductionNumber, Products.GroupName, Products.FullName FROM            DynamicArticle_ArticleResult AS DAAR INNER JOIN
                     ProductManager_Products AS Products ON Products.ItemID = DAAR.ItemID INNER JOIN
                     SalesTable AS ST ON ST.Id = DAAR.SalesID INNER JOIN
                     OrderSalesLines AS OSL ON OSL.SalesLineID = Products.SalesLineID AND OSL.Depth = 0 INNER JOIN
                     SalesLines AS SL ON SL.Id = Products.SalesLineID INNER JOIN
                     master.dbo.spt_values AS spt ON spt.type = 'P' AND spt.number < SL.Quantity WHERE (Products.Id IN (116994,116993)) AND (DAAR.Name = 'Panel' OR
                     DAAR.Name = 'KlassiekPaneel')

有没有办法阻止这种转换错误？

亲切的问候，

原来我对订单行的加入导致了这个问题。虽然每个产品返回一行。我删除了它，现在运行正常。
