我正在编写一个存储过程来获取基于CATEGORY ID传递给它的详细信息,如果CATEGORY ID传递给它不为空,我正在获取基于CATEGORY ID,如果CATEGORY ID为空,我正在获取CATEGORY ID除之外的所有详细信息3,任何人都可以帮助我解决这个问题。

我的程序是这样的:

CREATE procedure [dbo].[SearchAssetdetails]
(
@assetCategory as int = null,
@assetType as int = null,
@assetDescription as nvarchar(200) = null,
@purchaseDate as datetime = null,
@validUpto as datetime = null)
as
begin
select ad.CategoryID,ad.AssetTypeId,ad.AssetDetailId,ad.AssetDescription,ad.Cost,ad.IsOwn,ad.LastModifiedby,ad.LastModifiedDatetime,ad.Location,ad.NoofLicences,ad.PurchaseDate,ad.SerialNumber,ad.ValidUpto,ad.VendorId,ad.Version,ad.WarrantyExpirationDate
 from AssetDetails ad where      
(ad.AssetDescription like (case when @assetDescription is not null then  '%'+@assetDescription+'%' else ad.AssetDescription end)        
and ad.CategoryID=(case when @assetCategory is not null then @assetCategory else ad.CategoryID   end)        
and ad.AssetTypeId=(case when @AssetType is not null then @AssetType else ad.AssetTypeId end)        
and ad.PurchaseDate=(case when @purchaseDate is not null then @purchaseDate else ad.PurchaseDate end)        
and ad.ValidUpto=(case when @validUpto is not null then @validUpto else ad.ValidUpto end)
 )  end;

由于ANDwhere 子句中的条件,您对其他参数的输入可能与输入不匹配,category idnull替换为3.

首先,选择带有其他参数的记录,看看是否有任何一个获取类别 id 为 3 的记录。我建议您向我们展示类别 id 为 3 的记录,以便我们更好地了解数据。

否则我相信没有错误。
