Question

我们有一个数据库，我们有大约100个同义词，如下所示：

 IF EXISTS (SELECT 1 FROM sys.objects Where type = 'SN' and name = 'CRM_ActivityPointerBase')
    DROP SYNONYM CRM_ActivityPointerBase
CREATE SYNONYM CRM_ActivityPointerBase FOR CRMPRODDB.TRAINING_MSCRM.dbo.ActivityPointerBase
GO 
 IF EXISTS (SELECT 1 FROM sys.objects Where type = 'SN' and name = 'CRM_AnnotationBase')
    DROP SYNONYM CRM_AnnotationBase
CREATE SYNONYM CRM_AnnotationBase FOR CRMPRODDB.TRAINING_MSCRM.dbo.AnnotationBase
GO
IF EXISTS (SELECT 1 FROM sys.objects Where type = 'SN' and name = 'CRM_SalesorderBase')
    DROP SYNONYM CRM_SalesOrderBase
CREATE SYNONYM CRM_SalesOrderBase FOR CRMPRODDB.TRAINING_MSCRM.dbo.SalesOrderBase
GO
IF EXISTS (SELECT 1 FROM sys.objects Where type = 'SN' and name = 'CRM_BusinessUnitBase')
    DROP SYNONYM CRM_BusinessunitBase
CREATE SYNONYM CRM_BusinessUnitBase FOR CRMPRODDB.TRAINING_MSCRM.dbo.BusinessUnitBase
GO

IF EXISTS (SELECT 1 FROM sys.objects Where type = 'SN' and name = 'CRM_SalesorderExtensionBase')
    DROP SYNONYM CRM_SalesOrderExtensionBase
CREATE SYNONYM CRM_SalesOrderExtensionBase FOR CRMPRODDB.TRAINING_MSCRM.dbo.SalesOrderExtensionBase
GO

有时我需要所有同义词指向CRMPRODDB.TRAINING_MSCRM，有时我需要所有同义词指向ANOTHERSERVER.myDATABASE。

我的想法是创建一个我只运行的函数，它只会更新每个同义词。

有人可以帮助我开始吗？

我想到这样的事情：

declare @myvar varchar
select @myvar ='CRMPRODDB.TRAINING_MSCRM'

IF EXISTS (SELECT 1 FROM sys.objects Where type = 'SN' and name = 'CRM_ActivityPointerBase')
    DROP SYNONYM CRM_ActivityPointerBase
EXECUTE ('CREATE SYNONYM CRM_ActivityPointerBase FOR ' + @myvar);

但我真的很喜欢你对标准做法的指导。

非常感谢你的帮助。

我会看database projects，它们设置起来有点麻烦，但可以做到这一点，你的定义看起来像这样：

CREATE SYNONYM CRM_SalesOrderExtensionBase FOR $(server).$(database).dbo.SalesOrderExtensionBase

并选择发布配置文件来替换变量。它们只是SQLCMD脚本，你可以在没有数据库项目的情况下做同样的事情。
