Question

I want to drop a database. I have used the following code, but to no avail.

public void DropDataBase(string DBName,SqlConnection scon)
{
    try
    {
        SqlConnection.ClearAllPools();
        SqlCommand cmd = new SqlCommand("ALTER DATABASE " + DBName + "     SET SINGLE_USER     WITH ROLLBACK IMMEDIATE", scon);
        cmd.CommandType = CommandType.Text;
        scon.Open();
        cmd.ExecuteNonQuery();
        scon.Close();

        SqlCommand cmddrpdb = new SqlCommand("drop database " + DBName + "", scon);
        cmddrpdb.CommandType = CommandType.Text;
        scon.Open();
        cmddrpdb.ExecuteNonQuery();
        scon.Close();
    }
    catch (Exception ex)
    {
        MessageBox.Show("DropDataBase : " +ex.Message);
    }
}

I am getting Error as cannot drop database because it is currently in use.
Please help me out in the above mentioned issue.

Answer 1

Someone connected to the database. Try to switch to another database and then, to drop it:

Try

SP_WHO to see who connected

and KILL if needed
