某处是否有“脚本表 - 合并”功能？

Question

在 SSMS 2008 R2 中，当我右键单击表时，我会看到“脚本表为”，然后是插入和更新选项。但是合并呢？合并实际上就是将这两者结合在一起。

我可以获得任何可以添加该选项的工具吗？（因此，我可以编写一个合并语句，准备好添加源信息（有点像插入和更新脚本已准备好添加要插入或更新的数据）。

SSMS 中没有执行此类操作的内置功能（我想通过外部插件可能可以实现）。

有一个由Micha\xc5\x82 Go\xc5\x82o\xc5\x9bsp_GenMerge编写的程序（根据 MIT 许可证授权），允许使用数据编写表脚本作为合并语句。

\n

示例场景：

\n

CREATE TABLE [Customer]  (\n   ID                   INT                  IDENTITY(1,1) CONSTRAINT PK_CUSTOMER PRIMARY KEY (ID),\n   FIRSTNAME            NVARCHAR(30)         NOT NULL,\n   LASTNAME             NVARCHAR(30)         NOT NULL,\n   CITY                 NVARCHAR(30)         NULL,\n   COUNTRY              NVARCHAR(30)         NULL,\n   PHONE                NVARCHAR(20)         NULL\n);\n\nINSERT INTO [Customer] ([FirstName],[LastName],[City],[Country],[Phone])\nVALUES(\'John\',\'Smith\',\'Berlin\',\'Germany\',\'12345\'),(\'Cathrine\',\'Fa\',\'Brasilia\',\'Brasil\',\'(3) 4324-4723\');\n

基本 SP 调用（它支持更多选项 - 请参阅文档）：

\n

EXEC sp_GenMerge @source_table = \'dbo.Customer\';\n

\n

输出：

\n

DECLARE @xml XML = N\'\n<!-- Insert the generated data here -->\n\';\n\n\nMERGE INTO dbo.Customer AS Target\nUSING (SELECT x.value(\'(@ID)\', \'int\') AS [ID]\n            , x.value(\'(@FIRSTNAME)\', \'nvarchar(30)\') AS [FIRSTNAME]\n            , x.value(\'(@LASTNAME)\', \'nvarchar(30)\') AS [LASTNAME]\n            , x.value(\'(@CITY)\', \'nvarchar(30)\') AS [CITY]\n            , x.value(\'(@COUNTRY)\', \'nvarchar(30)\') AS [COUNTRY]\n            , x.value(\'(@PHONE)\', \'nvarchar(20)\') AS [PHONE]\n        FROM @xml.nodes(\'v\') AS t(x)) AS Source ([ID], [FIRSTNAME], [LASTNAME], [CITY], [COUNTRY], [PHONE])\n  ON (Target.[ID] = Source.[ID])\nWHEN NOT MATCHED BY TARGET\nTHEN INSERT([FIRSTNAME]\n          , [LASTNAME]\n          , [CITY]\n          , [COUNTRY]\n          , [PHONE])\n     VALUES(Source.[FIRSTNAME]\n          , Source.[LASTNAME]\n          , Source.[CITY]\n          , Source.[COUNTRY]\n          , Source.[PHONE])\nWHEN MATCHED AND EXISTS (SELECT Target.[FIRSTNAME]\n                              , Target.[LASTNAME]\n                              , Target.[CITY]\n                              , Target.[COUNTRY]\n                              , Target.[PHONE]\n                         EXCEPT\n                         SELECT Source.[FIRSTNAME]\n                              , Source.[LASTNAME]\n                              , Source.[CITY]\n                              , Source.[COUNTRY]\n                              , Source.[PHONE])\nTHEN UPDATE SET Target.[FIRSTNAME] = Source.[FIRSTNAME]\n              , Target.[LASTNAME] = Source.[LASTNAME]\n              , Target.[CITY] = Source.[CITY]\n              , Target.[COUNTRY] = Source.[COUNTRY]\n              , Target.[PHONE] = Source.[PHONE];\nGO\n

\n

并将行脚本化为 XML 有效负载：

\n

<v ID="1" FIRSTNAME="John" LASTNAME="Smith" CITY="Berlin" COUNTRY="Germany" PHONE="12345" />\n<v ID="2" FIRSTNAME="Cathrine" LASTNAME="Fa" CITY="Brasilia" COUNTRY="Brasil" PHONE="(3) 4324-4723" />\n
