I obtain this error: Error -2147217900 Specified owner name 'dbo'...

If you obtain the following error by making a query on MSSQL
 
Errore -2147217900 Specified owner name 'dbo' either does not exist or you do not have permission to use it

The owner name for all the objects created by the users must be the same of the login connected to MSSQL service: it cannot be dbo because the users do not have the dbowner permissions, option possible only on your own dedicated server

Therefore by carrying out instructions such as this

CREATE TABLE [dbo].[tbl_tablename] (
 [col_id] [int] IDENTITY (1, 1) NOT NULL ,
 [col_user] [nvarchar] (20) NOT NULL ,
      [col_cat] [int] NULL ,
      [col_sub] [int] NULL ,
      [col_state] [int] NULL ,
 [col_city] [nvarchar] (50) NULL ,
 [col_key] [nvarchar] (100) NULL ,
 [col_type] [nvarchar] (1) NULL ,
 [col_both] [nvarchar] (1) NULL ,
 [col_min] [money] NULL ,
 [col_max] [money] NULL ,
) ON [PRIMARY]
GO
you need to replace in
 CREATE TABLE [dbo].[tbl_tablename]

 dbo user with their own login to the MSSQL service, for example MSSql10059 and therefore

CREATE TABLE [MSSql10059].[tbl_tablename]
