偷师于吉普赛的歌。。。

直接上代码了

USE tempdb
GO
-- 定义中转表，结构与你需要输出的一致，但需要增加 sessionId 和 addTime,
-- sessionId 防止并发时出现无法辨别的问题
-- addTime 记录插入时间，便于观察
IF OBJECT_ID('dbo.tmp_transfer1') IS NOT NULL DROP TABLE tmp_transfer1
IF OBJECT_ID('dbo.tmp_transfer2') IS NOT NULL DROP TABLE tmp_transfer2
GO
CREATE TABLE dbo.tmp_transfer1(sessionId VARCHAR(50),addTime DATETIME, id INT,n VARCHAR(50))
CREATE TABLE dbo.tmp_transfer2(sessionId VARCHAR(50),addTime DATETIME, id INT,n VARCHAR(50))
GO
IF OBJECT_ID('Proc_A') IS NOT NULL DROP PROC Proc_A
IF OBJECT_ID('Proc_B') IS NOT NULL DROP PROC Proc_B
