好吧,这可能是我的另一个不好的问题,但我仍然充满希望。如果你查看我最近的question,那是一种绝望的尝试,以简化将存储过程嵌套在另一个内部的需要。
基本上,我需要从视图(view_game)中选择满足特定条件的几行,并生成其他视图(view_pupil_game,view_pupil_doubles,view_game_winner)并组合输出以创建另一个视图。
但是,展望替代方案我想创建一个存储过程,它接受一个参数并将其提供给其他过程,并将输出作为结果集并使用它来完成主过程。
请帮助我,给出一个将存储过程视为表(或记录集)并在存储过程中查询它的简单示例
要想知道我想要什么,这是一个虚拟查询
begin
Create procedure someProcedure
@param1 int(3),
@param2 int(3)
as
begin
SELECT * FROM <anotherStoreProcedure @param1, @param2> as set1
inner join <anotherStoreProcedure2 @param1, @param2> as set2 on set2.id=set1.id
end
go

可能你需要这样的东西:
-- tables to save result of calling stored procs below
DECLARE @set1 AS TABLE(id INT, value1 varchar(10))
DECLARE @set2 AS TABLE(id INT, value2 varchar(10))
-- save result of dbo.anotherStoreProcedure call into table variable @set1
INSERT INTO @set1 (id, value1)
EXEC dbo.anotherStoreProcedure @param1, @param2
-- save result of dbo.anotherStoreProcedure2 call into table variable @set2
INSERT INTO @set2 (id, value12)
EXEC dbo.anotherStoreProcedure2 @param1, @param2
SELECT
*
FROM
set1
INNER JOIN
set2
ON
set2.id = set1.id

您可以创建返回某些数据的表值UDF,然后您可以在SP中使用这些UDF。
示例:
create function SomeFunction1
(
@param1 int,
@param2 int
) returns table as
return
(
-- Some query that returns something
select 1 as id,
@param1 as Col1,
'SomeFunc1' as Col2
union all
select 2,
@param2,
'SomeFunc1' as Col2
)
go
create function SomeFunction2
(
@param1 int,
@param2 int
) returns table as
return
(
-- Some query that returns something else
select 1 as id,
@param1 as Col1,
'SomeFunc2' as Col2
union all
select 2,
@param2,
'SomeFunc2' as Col2
)
go
create procedure SomeProcedure
@param1 int,
@param2 int
as
begin
-- SP that uses the UDF and joins on column id
select *
from dbo.SomeFunction1(@param1, @param2) as set1
inner join SomeFunction2(@param1, @param2) as set2
on set2.id=set1.id
end
像这样使用:
exec SomeProcedure 3, 4
结果:
id Col1 Col2 id Col1 Col2
----------- ----------- --------- ----------- ----------- ---------
1 3 SomeFunc1 1 3 SomeFunc2
2 4 SomeFunc1 2 4 SomeFunc2
