如何连接数字和字符串以在 TSQL 中格式化数字

我有以下功能

ALTER FUNCTION [dbo].[ActualWeightDIMS]
(
    -- Add the parameters for the function here
    @ActualWeight int,
    @Actual_Dims_Lenght int,
    @Actual_Dims_Width int,
    @Actual_Dims_Height int
)
RETURNS varchar(50)
AS
BEGIN

DECLARE @ActualWeightDIMS varchar(50);
--Actual Weight
     IF (@ActualWeight is not null) 
          SET @ActualWeightDIMS = @ActualWeight;
--Actual DIMS
     IF (@Actual_Dims_Lenght is not null) AND 
          (@Actual_Dims_Width is not null) AND (@Actual_Dims_Height is not null)
          SET @ActualWeightDIMS= @Actual_Dims_Lenght + 'x' + @Actual_Dims_Width + 'x' + @Actual_Dims_Height;


     RETURN(@ActualWeightDIMS);

END

但是当我try 使用它时，当我使用下面的select语句时，出现了以下错误"将varchar值'x'转换为数据类型int时，转换失败"

select 
 BA_Adjustment_Detail.ID_Number [ID_Number],
 BA_Adjustment_Detail.Submit_Date [Submit_Date],
 BA_Category.Category [category],
 BA_Type_Of_Request.Request [Type_Of_Request],
 dbo.ActualWeightDIMS(BA_Adjustment_Detail.ActualWeight,BA_Adjustment_Detail.Actual_Dims_Lenght,BA_Adjustment_Detail.Actual_Dims_Width,BA_Adjustment_Detail.Actual_Dims_Height) [Actual Weight/DIMS],
 BA_Adjustment_Detail.Notes [Notes],
 BA_Adjustment_Detail.UPSCustomerNo [UPSNo],
 BA_Adjustment_Detail.TrackingNo [AirbillNo],
 BA_Adjustment_Detail.StoreNo [StoreNo],
 BA_Adjustment_Detail.Download_Date [Download_Date],
 BA_Adjustment_Detail.Shipment_Date[ShipmentDate],
 BA_Adjustment_Detail.FranchiseNo [FranchiseNo],
 BA_Adjustment_Detail.CustomerNo [CustomerNo],
 BA_Adjustment_Detail.BillTo [BillTo],
 BA_Adjustment_Detail.Adjustment_Amount_Requested [Adjustment_Amount_Requested]
from BA_Adjustment_Detail
inner join BA_Category 
on BA_Category.ID = BA_Adjustment_Detail.CategoryID
inner join BA_Type_Of_Request
on BA_Type_Of_Request.ID = BA_Adjustment_Detail.TypeOfRequestID

我想做的是，如果实际重量不为空，那么返回"实际重量/尺寸"的实际重量，或者使用实际长度、宽度和高度.

如果是DIMS，那么我想将输出格式化为LenghtxWidhtxHeight(15x10x4).实际重量、Adcutal_Dims_长度、宽度和高度均为整数，但"实际重量/Dims"的输出应为varchar(50).

我哪里弄错了？

感谢

编辑:用户只能在ASP上 Select 权重或DIMS.net页面，如果用户 Select 了DIM，则必须提供长度、宽度和高度.否则它会在ASP上抛出错误.网页.我应该担心sql方面的问题吗？
