SQL Server 在一个存储过程中调用另外一个存储过程获取返回值，出现报错

我需要在一个SP中（名称为SP1），调用另外一个DB的SP（名称为SP2），将SP2返回的值存入一个表中的时候出现报错了。 SP1的语句如下：
insert into tempSendQWMSData
EXEC [*******].QWMS.DBO.SP_QueryData_SMT '218',‘331’,'1187'
报错信息如下： OLE DB provider "SQLNCLI10" for linked server "10.17.32.33" returned message "The partner transaction manager has disabled its support for remote/network transactions.".
Msg 7391, Level 16, State 2, Line 2
The operation could not be performed because OLE DB provider "SQLNCLI10" for linked server "10.17.32.33" was unable to begin a distributed transaction.

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 a
begin
...
insert #table exec b
end

procedure b
begin
...
insert #table exec c
select * from #table
end

procedure c
begin
...
select * from sometable
end

--这里a调b的结果集，而b中也有这样的应用b调了c的结果集，这是不允许的，
--会报“INSERT EXEC 语句不能嵌套”错误。在实际应用中要避免这类应用的发生。

第三种方法:声明一个变量,用exec(@sql)执行:

1);EXEC 执行SQL语句

declare @rsql varchar(250)
declare @csql varchar(300)
declare @rc nvarchar(500)
declare @cstucount int
declare @ccount int
set @rsql='(select Classroom_id from EA_RoomTime where zc='+@zc+' and xq='+@xq+' and T'+@time+'=''否'') and ClassroomType=''1'''
--exec(@rsql)
set @csql='select @a=sum(teststucount),@b=sum(classcount) from EA_ClassRoom where classroom_id in '
set @rc=@csql+@rsql
exec sp_executesql @rc,N'@a int output,@b int output',@cstucount output,@ccount output--将exec的结果放入变量中的做法
--select @csql+@rsql
--select @cstucount

什么叫做调用另一个DB的SP 是2个数据库？
