问题 Is there any way to determine from within SQL Server (I'm on 2012 FYI) if a SP's parameters have default values? There are other threads on this, however the suggestions don't seem to get me this information accurately. Here are a couple of things I've tried; select * from sys.objects so join sys.parameters sp on so.object_id = sp.object_id where so.type='P' and so.name = 'someSp' The above query returns a number of columns that sound like I'm barking up the right tree (has_default_value,

问题 I've just started teaching myself SQL recently and have been able to piece together almost everything I need from various tutorials, but this one has me banging my head against the wall. We have a table that contains all the bill of material information for our products. I only need 4 of the columns from it - PPN_I, CPN_I, QUANTITY_I, BOMNAME_I - which are Item Number, Raw Material number, quantity, and the BOMName, respectively. Many of the BOMs contain subassemblies. I need a result set

问题 If I create a database using 2012 and work and add that info to it, if I were to script the database after, would I be able to run the script in 2008 and have everything work A.O.K? 回答1: A script? Yes. Well, let me rephrase: it depends. As long as your objects don't use any 2012-specific features, you will be able to script out the schema using Management Studio or a variety of 3rd party tools (I blogged about some options here). Many of the tools also offer options (or companion tools) to

问题 I am trying to use SimpleMembership in my MVC 4 for the first time and I already have an existing database and EF5 model created based on it! I searched a lot but I cant find how I could use it in my case and also to have everything under my own model. It would be great if somebody can give me an idea how to do this. Thanks 回答1: Purely as a point of reference, it might be a good idea to create a new Internet Application template of an ASP.NET MVC 4 Web Application project (i.e. via File > New

问题 I've written two stored procedure one with sp_executesql and other doesn't have sp_executesql both are executing properly same results, I didn't get what is the difference here between EXEC (@SQL) vs EXEC sp_executesql @SQL, N'@eStatus varchar(12)', @eStatus = @Status and How EXEC(@SQL) is prone to SQL injection and sp_executesql @SQL...... isn't? Below Stored Procedure without sp_executesql ALTER proc USP_GetEmpByStatus ( @Status varchar(12) ) AS BEGIN DECLARE @TableName AS sysname =

问题 I wrote a query SELECT * FROM Users WHERE UserName = 'admin ' by mistaken typing. But I found that the result is as the same as SELECT * FROM Users WHERE UserName = 'admin' It seems that the empty space at the end is ignored by SQL Server automatically. Can anybody tell me why? FYI, the column UserName is of type nvarchar(MAX) . 回答1: SQL Server is following the ANSI/ISO standard for string comparison. The article How SQL Server Compares Strings with Trailing Spaces explains this in detail.
