Question

我可以在视图中设置多于1个结果的参数吗？

Declare @input varchar(1000)
SET @input = (select order from orderlist_view)

我收到的错误是：Subquery returned more than 1 value. This is not permitted when the subquery follows =, !=, <, <= , >, >= or when the subquery is used as an expression.

Answer 1

您可以使用XML完成此操作：

Declare @input varchar(1000)


select @input = stuff((select distinct ',' + quotename(order)
            from orderlist_view
            for xml path(''), type).value('.', 'nvarchar(max)'),1,1,'')

这项工作可以吗？

Answer 2

您可以改为声明一个表，并执行以下任务：

declare @table table(column_name varchar(1000))
insert @table
select order from orderlist_view

-打印声明的表变量

select * from @table.

从选择结果约束中设置
