【Merge】写法报错

[不胖到130不改名字]

a表是原表
c表示目标表
表结构都是一样的

CREATE TABLE [dbo].[a](
	[pgvl_id] [INT] IDENTITY(1,1) NOT NULL,
	[pgvl_serial_number] [VARCHAR](50) NOT NULL,
	[pgvl_wo_nbr] [VARCHAR](20) NULL,
	[pgvl_part] [VARCHAR](20) NULL,
	[pgvl_machine_name] [VARCHAR](50) NOT NULL,
	[pgvl_terminal_id] [INT] NOT NULL,
	[pgvl_step_seq] [VARCHAR](50) NULL,
	[pgvl_step_name] [VARCHAR](100) NULL,
	[pgvl_item_name] [VARCHAR](50) NULL,
	[pgvl_item_para] [VARCHAR](400) NULL,
	[pgvl_lsl] [VARCHAR](50) NULL,
	[pgvl_usl] [VARCHAR](50) NULL,
	[pgvl_values] [VARCHAR](50) NULL,
	[pgvl_result] [VARCHAR](10) NULL,
	[isenable] [INT] NOT NULL,
	[modtime] [DATETIME] NOT NULL,
	[acctid] [INT] NOT NULL,
	[sid] [INT] NOT NULL
) ON [PRIMARY]

下面是merge写法

SET IDENTITY_INSERT test.dbo.c ON;

MERGE INTO test.dbo.c AS t
USING test.dbo.a AS s
ON (t.pgvl_id = s.pgvl_id)
--目标数据表存在该数据

--源数据表不存在该数据
WHEN NOT MATCHED BY SOURCE
THEN DELETE;

SET IDENTITY_INSERT test.dbo.c OFF;

一直报错

消息 102，级别 15，状态 1，第 3 行
'MERGE' 附近有语法错误。

数据库是2008 R2

知道原因了 数据库=》选项=》兼容模式要设置2008

[不胖到130不改名字]

不过为什么我数据库明明是2008 R2 兼容模式却选不了2008？
