Transaction

Hi All,

Someone please explain me how can this happen .. I have my own DBA database. Database script is given bellow


CREATE DATABASE [DBA] ON  PRIMARY 
( NAME = N'DBA_Data', FILENAME = N'N:\SrOtherDbs_data\dba_data.mdf' , SIZE = 13593KB , MAXSIZE = UNLIMITED, FILEGROWTH = 10%)
 LOG ON 
( NAME = N'DBA_Log', FILENAME = N'O:\SrOtherDbs_log\dba_log.ldf' , SIZE = 9216KB , MAXSIZE = UNLIMITED, FILEGROWTH = 10%)
GO
ALTER DATABASE [DBA] SET COMPATIBILITY_LEVEL = 100
GO
IF (1 = FULLTEXTSERVICEPROPERTY('IsFullTextInstalled'))
begin
EXEC [DBA].[dbo].[sp_fulltext_database] @action = 'disable'
end
GO

Strange behaviour of transaction.. test table

SET ANSI_NULLS ON
GO
SET QUOTED_IDENTIFIER ON
GO
SET ANSI_PADDING ON
GO
CREATE TABLE [dbo].[Human](
	[H_id] [int] NULL,
	[H_Name] [varchar](10) NULL
) ON [PRIMARY]

GO

SET ANSI_PADDING OFF
GO

INSERT INTO [dbo].[Human](H_id,H_Name) VALUES(1,'Mark'),(2,'Steve')



Open a new query window 

BEGIN TRAN	
DELETE FROM  [dbo].[Human]
--ROLLBACK

o/p
(2 row(s) affected)


Open 2nd query window and run 
SELECT * FROM   [Human]

The above code returns two record 
Executed this..
INSERT INTO [dbo].[Human] VALUES(3,'vgfg')
o/p
(1 row(s) affected)
Then executed this

DBCC OPENTRAN
o/p

Why the open tran not preventing the insert.. Interesting thing is this happening only on this database.. all other db insert query get blocked.. 

Why only in this database.. what am I missing..
