我们正在从SQL Server 2005升级到2008。几乎将2005实例中的每个数据库都设置为2000兼容模式,但是我们正在跳至2008。我们的测试已经完成,但是我们了解到,我们需要获取更快。
我发现了一些存储过程,这些存储过程要么从丢失的表中选择数据,要么尝试对不存在的列进行ORDER BY列。
包装SQL以在SET PARSEONLY ON中创建过程,并在try / catch中捕获错误只能捕获ORDER BY中的无效列。从丢失的表中选择数据的过程找不到错误。但是,SSMS 2008的智能感知确实可以找到问题,但是我仍然可以继续并成功运行该程序的ALTER脚本,而不会抱怨。
那么,为什么我什至无法创建一个在运行时失败的过程呢?有没有比我尝试过的工具更好的工具?
我发现的第一个工具不是很有用:CodeProject的DbValidator,但是它发现的问题比我在SqlServerCentral上发现的脚本无效的问题要少,后者发现了无效的列引用。

您可以选择不同的方式。首先SQL Server 2008中的 支持的依赖 存在于存储过程的DB包容性依赖(见http://msdn.microsoft.com/en- us/library/bb677214%28v=SQL.100%29.aspx,HTTP:/ /msdn.microsoft.com/en- us/library/ms345449.aspx和http://msdn.microsoft.com/en- us/library/cc879246.aspx)。您可以使用sys.sql_expression_dependencies和sys.dm_sql_referenced_entities进行查看和验证。
但是,验证所有存储过程的最简单方法是:
如果升级数据库,则不会验证现有的存储过程,但是如果创建新的存储过程,则将验证该过程。因此,在导出和导出所有存储过程之后,您将收到报告的所有现有错误。
您还可以使用以下代码查看和导出存储过程的代码
SELECT definition FROM sys.sql_modules WHERE object_id = (OBJECT_ID(N'spMyStoredProcedure'))
UPDATED :若要查看存储过程spMyStoredProcedure引用的对象(如表和视图),可以使用以下命令:
SELECT OBJECT_NAME(referencing_id) AS referencing_entity_name ,referenced_server_name AS server_name ,referenced_database_name AS database_name ,referenced_schema_name AS schema_name , referenced_entity_name FROM sys.sql_expression_dependencies WHERE referencing_id = OBJECT_ID(N'spMyStoredProcedure');
更新2 :在对我的答案的评论中,Martin Smith建议使用sys.sp_refreshsqlmodule而不是重新创建存储过程。所以用代码
sys.sp_refreshsqlmodule
SELECT 'EXEC sys.sp_refreshsqlmodule ''' + OBJECT_SCHEMA_NAME(object_id) + '.' + name + '''' FROM sys.objects WHERE type in (N'P', N'PC')
一个接收脚本,该脚本可用于验证存储过程的依赖性。输出将如下所示(AdventureWorks2008的示例):
EXEC sys.sp_refreshsqlmodule 'dbo.uspGetManagerEmployees' EXEC sys.sp_refreshsqlmodule 'dbo.uspGetWhereUsedProductID' EXEC sys.sp_refreshsqlmodule 'dbo.uspPrintError' EXEC sys.sp_refreshsqlmodule 'HumanResources.uspUpdateEmployeeHireInfo' EXEC sys.sp_refreshsqlmodule 'dbo.uspLogError' EXEC sys.sp_refreshsqlmodule 'HumanResources.uspUpdateEmployeeLogin' EXEC sys.sp_refreshsqlmodule 'HumanResources.uspUpdateEmployeePersonalInfo' EXEC sys.sp_refreshsqlmodule 'dbo.uspSearchCandidateResumes' EXEC sys.sp_refreshsqlmodule 'dbo.uspGetBillOfMaterials' EXEC sys.sp_refreshsqlmodule 'dbo.uspGetEmployeeManagers'
