Hello dear friends
My friend used my program from sql 2008, sql express 2008 I installed it on another system, but I do not want to attach my database.
The Internet had some way of using the command prompt
And use the command
sqlcmd-S. \ SQLEXPRESS
The error was still
Another one I read that I should install SQL engine service how I did it
Now thanks to my dear friends, if anyone has a solution
