Is there a table designer for VS2010 database project?

阅读更多关于 Is there a table designer for VS2010 database project?

问题 Am I missing something here? It seems that the only options to create a new table in a database project in VS2010 is: Create a table object as a file, then create all constraints (defaults) as separate files, then create each index as a separate file, and primary key as a separate file and on and on... Or Create the entire table schema using the table designer in SSMS and then use the schema compare tool to create a single monolithic file of SQL statements for each element of the table and

Why does Schema Compare in Visual Studio 2010 show differences when there are none?

问题 I had hoped that Visual Studio 2010 would have brought some improvements to the Schema Comparison function. I suspect there are some, but I can't get something basic working. I've sucked in a schema from a SQL Server 2005 database. Then to assure things were working, I did a schema compare choosing the database as the source and my schema project as the target. They were in synch. When you filter to view only "Non-skip Objects", no objects are listed. This tells me that the schemas do indeed

All I can find online involves tempdb. I need to substitute [MyDatabase].[dbo].[MyTable] with [$(DatabaseName)].[dbo].[MyTable]. This cleared up the warnings. Thanks for your help. In your [dbo].[MyProc] procedure you reference [MyDatabase].[dbo].[MyItem] which is probably not part of your DB

Does wrapping nullable columns in ISNULL cause table scans?

阅读更多关于 Does wrapping nullable columns in ISNULL cause table scans?

Code analysis rule SR0007 for Visual Studio 2010 database projects states that: You should explicitly indicate how to handle NULL values in comparison expressions by wrapping each column that can contain a NULL value in an ISNULL function. However code analysis rule SR0006 is violated when: As part of a comparison, an expression contains a column reference ... Your code could cause a table scan if it compares an expression that contains a column reference. Does this also apply to ISNULL, or does ISNULL never result in a table scan? Yes it causes table scans. (though seems to get optimised out
