I currently have a database table setup as follows (EAV - business reasons are valid): Id - int (PK) Key - unique, varchar(15) Value - varchar(1000) This allows me to add in mixed values into my databse as key/value pairs. For example: 1 | 'Some Text' | 'Hello World' 2 | 'Some Number' | '123456' etc. In my C# code I use ADO.Net using reader.GetString(2); to retrieve the value as a string, then have my code elsewhere convert it as needed, for example... Int32.ParseInt(myObj.Value); . I'm looking at enhancing my table by possibly changing the value column to a sql_variant datatype, but I don't

SQLGetDiagRec returns a native error code. Is there anywhere an overview of the error codes of SQL Server 2012? I couldn't find anything on MSDN. I'm unable to find a list of the individual codes in the internet. However I did find a list of the severity levels here on MSDN. They are as follows: Severity level / Description 0-9: Informational messages that return status information or report errors that are not severe. The Database Engine does not raise system errors with severities of 0 through 9. 10: Informational messages that return status information or report errors that are not severe.

I want to connect Matlab to Sql server . this is my code: db = database('ChifcoProd-2013-12-12-11-37', '', '', 'sqljdbc4.jar',... 'jdbc:microsoft:sqlserver://localhost:1433;database=ChifcoProd-2013-12-12-11-37') error: JDBC Driver Error: sqljdbc4.jar. Driver Not Found/Loaded the driver is already installed and I added the path to javaclasspath but it doesn't work. Try using the Help within MatLab, its very helpful. You are using the correct database connection: conn = database(instance,username,password,driver,databaseurl) The example provided by MatLab looks like this: Connect to an Oracle

A database that was originally from SQL Server 2008, was restored into SQL Server 2012. A backup from SQL Server 2012 was made and I am trying to restore it on my local SQL Server 2008 Express. However I get an error 'Specified cast is not valid' (SQLManagerUI). I have generated an SQL Script from 2012 and set it so that it will generate with compatibility to SQL Server 2008. However it is a large sql file, around 700mb. I recall before that I had tried to run a script of that size before on my local SQLExpress and also got an error. Is there a way I can get a "large" database from SQL Server

I create a DbGeography-point like this: String selectedLocation = String.Format("POINT ({0} {1})", lon, lat).Replace(",", "."); DbGeography selectedLocationGeo = DbGeography.FromText(selectedLocation, 4326); I also have a radius R. I want to create a curvepolygon with the shape of a circle with the specified radius from the point-coordinate. Be aware that I am using DbGeography, and not DbGeometry. How do I create the CIRCULARSTRING? Or is there a better way than using a CIRCULARSTRING? Something like this perhaps? String polyString = String.Format("CURVEPOLYGON(CIRCULARSTRING(xx yy, xx yy, xx
