if object_id('p1','p') is not null
drop proc p1
go
create proc p1 as
create table #t(id int)
insert #t select 100
select * from #t
go

if object_id('p2','p') is not null
drop proc p2
go
create proc p2 as
if object_id('tempdb..#t') is not null
    insert #t exec p1
else
begin
    create table #t(id int)
    insert #t exec p1
end
select * from #t
go

if object_id('p3','p') is not null
drop proc p3
go
create proc p3 as
create table #t(id int)
insert #t exec p2
select * from #t
go


exec p1
exec p2
exec p3 --INSERT EXEC 语句不能嵌套。

用临时表的方法，
        IF object_id('[tempdb].[dbo].#tmp') IS NOT NULL --判断临时表#tmp是否存在,存在则删除
            drop table #tmp
        select * into #tmp from tablename where 1=2 --创建临时表#tmp,其结构与tablename相同

        declare @QueryString nvarchar(1000) --动态查询语名变量(注：必须为ntext或nchar哐nvarchar类型，不能是varchar类型)
        set @QueryString='select * from tablename '
        insert into #tmp(field1,field2,...) exec(@querystirng)

探讨

试了下
消息 8164，级别 16，状态 1，过程 p2，第 3 行
An INSERT EXEC statement cannot be nested.

能不能把PRO2改成表函数

SQL code
那只能用存储过程调用存储过程了
参考一下吧  临时表没办法嵌套 考虑用output来做
第一种方法: 使用output参数

USE AdventureWorks;
GO
IF OBJECT_ID ( 'Production.usp_GetList', 'P' ) IS NOT NULL 
    DROP PROCEDURE Production.usp_GetList;
GO
CREATE PROCEDURE Production.usp_GetList @product varchar(40) 
    , @maxprice money 
    , @compareprice money OUTPUT
    , @listprice money OUT
AS
    SELECT p.name AS Product, p.ListPrice AS 'List Price'
    FROM Production.Product p
    JOIN Production.ProductSubcategory s 
      ON p.ProductSubcategoryID = s.ProductSubcategoryID
    WHERE s.name LIKE @product AND p.ListPrice < @maxprice;
-- Populate the output variable @listprice.
SET @listprice = (SELECT MAX(p.ListPrice)
        FROM Production.Product p
        JOIN  Production.ProductSubcategory s 
          ON p.ProductSubcategoryID = s.ProductSubcategoryID
        WHERE s.name LIKE @product AND p.ListPrice < @maxprice);
-- Populate the output variable @compareprice.
SET @compareprice = @maxprice;
GO


另一个存储过程调用的时候:

Create Proc Test
as
DECLARE @compareprice money, @cost money 
EXECUTE Production.usp_GetList '%Bikes%', 700, 
    @compareprice OUT, 
    @cost OUTPUT
IF @cost <= @compareprice 
BEGIN
    PRINT 'These products can be purchased for less than 
    $'+RTRIM(CAST(@compareprice AS varchar(20)))+'.'
END
ELSE
    PRINT 'The prices for all products in this category exceed 
    $'+ RTRIM(CAST(@compareprice AS varchar(20)))+'.'
第二种方法:创建一个临时表

create proc GetUserName
as
begin
    select 'UserName'
end

Create table #tempTable (userName nvarchar(50))
insert into #tempTable(userName)
exec GetUserName

select #tempTable

--用完之后要把临时表清空
drop table #tempTable--需要注意的是，这种方法不能嵌套。例如：

  procedure
