SQL Server 生成 Visual Studio 声称是错误的代码？

Question

我正在与数据库同步的（维护不善的）VS2012 SqlServer 项目中有几十个 .sql 文件。我无法进行架构比较，因为 VS 抱怨存在构建错误。数据库将优先于 SQL 项目的内容，但我对一个 .sql 中的错误特别感到困惑：

USE [ePostRxIS] /* SQL70001: This statement is not recognized in this context */

GO
CREATE NONCLUSTERED INDEX IDX_SpyGlass_Audit_History
ON [SpyGlass].[Audit] ([AuditTypeUID],[EntityTypeUID],[EntityUID],[CreatedDateTimeUTC])
INCLUDE (Description)

这是 .sql 的内容（添加了指示错误的 cmets），但如果我转到 SQL Server Management Studio，右键单击有问题的表（审核），将表编写为 > CREATE To，然后创建的脚本是正是 SQL 项目所拥有的。 VS 项目的目标平台设置为 SQL Server 2012，这是正确的目标环境。

我该怎么做才能让两者达成一致？我很想用数据库包含的内容重新创建项目，重新开始，但如果 VS 抱怨生成的代码，我该怎么办？如果我确实更正了 VS 项目以使其没有构建错误，那么架构比较不会不断告诉我存在差异吗？

SSDT 和 DB 项目只能识别“CREATE”语法，不能识别“USE”和“SET”命令。把这些从你的项目文件中拿出来，你应该会很好。

如果您最初尝试将整个数据库置于版本控制中，请考虑将其导入。您还可以考虑使用模式比较工具将数据库（作为源）与您的项目（作为目标）进行比较。
