问题 I'm trying to do the Code First Walkthrough of the entity framework ( http://blogs.msdn.com/b/adonet/archive/2011/09/28/ef-4-2-code-first-walkthrough.aspx ). I have the latest SQL Server Express and when I check my versions available via command line ( sqllocaldb info ): I see localdbApp1 and v11.0. When I try to run the walkthrough with a few minor tweaks, I get a can't connect error. My app.config looks like this: <parameter value="Server=(LocalDB)\v11.0; Integrated Security=True;

问题 I've got 34 rows in a database, each row has a column containing xml - the xml is actually in an NVARCHAR(MAX) column not an XML column. For each row I am selecting values in the xml elements as a single resultset. The performance is pretty poor. I've tried two different queries. The first takes roughly 22 seconds to execute and the second takes 7. Even at 7 seconds, this is far slower than optimal, I'm hoping for 1-2 seconds at most. So then I read a rumor online that if you convert the

问题 I was wondering if someone could provide me an easy way to extract the names into different columns as below. There is a comma after the Last Name and space between First Name, Middle Initial, and Suffix. Greatly appreciate it. Stored Data: Name Walker,James M JR Smith,Jack P Smith,Whitney Required result: LastName FirstName Suffix Walker James JR Smith Jack Smith Whitney Tried Code: select top 5 Name, LEFT(Name, CHARINDEX(',', Name) - 1) AS LastName, right(Name, len(Name) - CHARINDEX(',',

问题 I have a case in which I have SQL code with an IF-ELSE block. The code in the IF portion should not be reached, but I still get an error when the SQL executes. In the code I first test for the linked server, and when that fails, @reval is set to 1 and the ELSE block should execute and avoid the code in the IF block that needs to query the linked server, but I get this error: Msg -1, Level 16, State 1, Line 0 SQL Server Network Interfaces: Error Locating Server/Instance Specified [xFFFFFFFF].

问题 Not duplicate. The problem here is it has different structure. and I have some restrictions of what I can change and what I can't. Here I have exact example, which other tickets don't. OPENROWSET cannot be applied either, because test1 loops through all dbs ( using EXEC sp_MSforeachdb @sql) . And I can't use it, because in OPENROWSET you have to specify from which db you are running procedure Suppose I have these two SPs: create procedure test1 @ProcName varchar(155) as begin if OBJECT_ID(

问题 I have a table called MyTextstable (myTextsTable_id INT, myTextsTable_text VARCHAR(MAX)) . This table has around 4 million records and I am trying to remove any instance of the ASCII characters in the following range(s) the VARCHAR(MAX) column myTextsTable_text . 00 - 08 11 - 12 14 - 31 127 I have written the following SQL query, which is taking under 10 minutes on SQL Server 2012, but failed to execute on SQL Server 2008 R2 even after two hours (so I stopped the execution). Please note I

问题 I am developing an SSIS package in VS 2012 that is being deployed to SQL Server 2012. The package is pulling data from an external database with a 32 bit driver and loading it into SQL Server 2012. I have the package set up so that it is using project parameters to store the connection strings. I can run the package from VS and I can also run the package via 32 bit dtexec. I cannot run the package from the SQL agent. I have the job set up so that it is using a ssis proxy account. I have also
