问题描述
我正在尝试调试其他人的 SQL 报告，并将基础报告查询放入 SQL 2012 的查询窗口中.
I'm trying to debug someone else's SQL reports and have placed the underlying reports query into a query windows of SQL 2012.
报告要求的参数之一是整数列表.这是通过多选下拉框在报告上实现的.报告的基础查询在 where 子句中使用这个整数列表，例如
One of the parameters the report asks for is a list of integers. This is achieved on the report through a multi-select drop down box. The report's underlying query uses this integer list in the where clause e.g.
select *
from TabA
where TabA.ID in (@listOfIDs)
我不想修改我正在调试的查询，但我不知道如何在 SQL Server 上创建一个可以保存此类数据的变量来测试它.
I don't want to modify the query I'm debugging but I can't figure out how to create a variable on the SQL Server that can hold this type of data to test it.
例如
declare @listOfIDs int
set listOfIDs = 1,2,3,4
没有可以保存整数列表的数据类型，那么如何在我的 SQL Server 上使用与报告相同的值运行报告查询?
There is no datatype that can hold a list of integers, so how can I run the report query on my SQL Server with the same values as the report?
推荐答案
表变量
declare @listOfIDs table (id int);
insert @listOfIDs(id) values(1),(2),(3);
select *
from TabA
where TabA.ID in (select id from @listOfIDs)
或
declare @listOfIDs varchar(1000);
SET @listOfIDs = ',1,2,3,'; --in this solution need put coma on begin and end
select *
from TabA
where charindex(',' + CAST(TabA.ID as nvarchar(20)) + ',', @listOfIDs) > 0
