我现在不知所措。似乎在太小的服务器上处理的数据太多。
最佳答案
修改内容为:
1)创建一个新的标量函数来测试分隔逗号文本中是否存在数据，无需创建#temp表来检查数据是否存在。
-- test if token exis in delimited comma string, use spli function
create FUNCTION [dbo].[inList]
(
@delimited NVARCHAR(MAX) ,
@token NVARCHAR(100)
)
RETURNS NVARCHAR(100)
as
begin
declare @retval NVARCHAR(100)
select @retval=data from
dbo.split(@delimited) t
where t.data=@token
return @retval
end
go
我们替换 where 条件中的表达式，如下例所示:
-- AND ( @ASSET_NO = '' OR u.ASSET_NO in ( SELECT ASSET_NO from #asset_nos ))
修改为:
AND ( @ASSET_NO = '' OR u.ASSET_NO = dbo.inlist(@ASSET_NO,u.ASSET_NO))
和所有分隔列表相同
2) 由于您使用了许多空参数，因此在执行前重新编译 SP 以获得新的执行计划( WITH RECOMPILE)

更新:
根据评论，
“您所描述的在存储过程中不起作用，因为参数值事先未知。”
参数值确实是已知的时间头，因为它们是在存储过程头中接收的。标量函数在调用时执行，并根据 SP 传递的参数返回值或 null。
例如:片段代码
AND ( @ASSETCODE = '' OR a.ASSETCODE =dbo.inlist(@ASSETCODE,a.ASSETCODE))
@ASSETCODE 是一个参数值(分隔列表)
a.ASSETCODE 是当前行的值
所以，这个表达式被及时评估并返回真/假
OP中使用的其他六个列表相同
以下测试用例模拟了我的回答中使用的标量函数 {inlist} 的使用:
create procedure test_delimeted_list (
@list1 nvarchar(100)
)
as
begin
select * from products p
where p.ProductID = dbo.[inList](@list1,p.productid)
end
go
测试 1:列表有一个值
exec test_delimeted_list '2,500,610' -- 2 is existing
北风数据库返回数据:
ProductID ProductName SupplierID CategoryID QuantityPerUnit UnitPrice UnitsInStock UnitsOnOrder ReorderLevel Discontinued
2 Chang 1 1 24 - 12 oz bottles 19.00 17 40 25 0
测试 2:列表为空
exec test_delimeted_list null
返回数据为空
我希望 OP 测试我的代码并为缺少或不起作用的内容提供评论。
