Question

I am using following code to detach my DB from SQL Server express. Please advise if there is something wrong with it. I am getting an error on it.

"Could not locate entry in sysdatabases for database 'EXEC master'. No entry found with that name. Make sure that the name is entered correctly."

The code I am using is

 Dim conn2 As New SqlConnection("Server=MyHomeServer\SQLExpress;Database=master;Trusted_Connection=False;User ID=sa;Password=abc123;")
    Dim cmd2 As New SqlCommand("", conn2)
    cmd2.CommandType = CommandType.StoredProcedure
    cmd2.CommandText = "EXEC master.dbo.sp_detach_db @dbname = N'MyHomeDBTestPWD'"
    conn2.Open()
    cmd2.Connection = conn2
    cmd2.ExecuteNonQuery()

You are assiging this the wrong way. You are allocating a proper SQL statement in the CommandText when you only need to add the Stored Procedure name. You will then need to add a Parameter to your SqlCommand.

Dim cmd2 As New SqlCommand("", conn2) 
cmd2.CommandType = CommandType.StoredProcedure
cmd2.CommandText = "sp_detach_db"
cmd2.Parameters.AddWithValue("@dbname", "MyHomeDBTestPWD")
cmd2.ExecuteNonQuery()

If you are alternatively wanting to execute your SQL statement, then you just need to change your CommandType to CommandType.Text
