我猜数据库已经存在，U可以通过尝试给您尝试创建的数据库提供不同的名称来尝试，或者从以下位置删除该数据库:

C:\ Program Files \ Microsoft SQL Server \ MSSQL.1 \ MSSQL \ Data

假设您的SQL Server安装在c:drive

希望这会有所帮助:)

Hi I am a student I installed the Micorsoft sql server 2008 R2 when I did my asp.net course now I am doing a introduction to sql course I thought of using the same sql server to create a database and to create a table but I having the following error

TITLE: Microsoft SQL Server Management Studio
------------------------------
Create failed for Database ''course''. (Microsoft.SqlServer.Smo)
For help, click: http://go.microsoft.com/fwlink?ProdName=Microsoft+SQL+Server&ProdVer=10.50.1600.1+((KJ_RTM).100402-1540+)&EvtSrc=Microsoft.SqlServer.Management.Smo.ExceptionTemplates.FailedOperationExceptionText&EvtID=Create+Database&LinkId=20476

I guess the database, already exists, U can try by giving different name to the database you are trying to create, or remove the database from this location:

C:\Program Files\Microsoft SQL Server\MSSQL.1\MSSQL\Data

assuming that your sql server is installed on c: drive

hope this helps :)
