Well if your discussing account creation, what he opened was probably an SQL script...
Code:
INSERT INTO [Auth].[dbo].[Account] ([account_id], [account], [password], [email], [password2], [block], [IP_user], [last_login_server_idx], [Admin], [point], [datePassword], [pk_], [creationDate_], [updateDate_], [creatorId_], [updatorId_], [portId_], [type_], [accessDate_]) VALUES ('3', 'Atif', 'ecfade2836414c54b8289c496820fe10', 'atif@localhost', 'mohcen213', '0', '127.0.0.1', '1', '1', '0', '2017-10-20', '1', '2017-10-20 18:56:17.000', '2017-10-20 18:56:21.000', '2017-10-20 18:56:30.000', '2017-10-20 18:56:33.000', 'rappelz', 'rappelz', '0');
Although you would be better off making the account_id in the account table an identity seed which I posted instruction for later in this thread...
[Only registered and activated users can see links. Click Here To Register...]
And then this SQL query...
[Only registered and activated users can see links. Click Here To Register...]
And you open those in Microsoft SQL Server Management Studio or (MSSMS) in order to execute them and that updates your account table with the data.
If you don't already have them saved as SQL query files then you can just open MSSMS and select "New Query" from the tool bar and copy and paste the query into the query window that opens up and execute it.
