This document is the specification of the Java API for Java Bean validation in Java EE and Java SE.The technical objective of this work is to provide a class level constraint declaration and validation facility for the Java application developer, as well as a constraint metadata repository and query API.Test_Table' GO --Recover the deleted data it with date range EXEC Recover_Deleted_Data_Proc 'test','dbo.Test_Table','2012-06-01','2012-06-30' Now,we have deleted data but in Hex values but SQL keeps this data in a specific sequence so we can easily recover it.This work is being conducted as part of JSR 303 under the Java Community Process Program.This specification is the result of the collaborative work of the members of the JSR 303 Expert Group.In all my years of working SQL server, one of the most commonly asked questions has always been “How can we recover deleted record?” Now, it is very easy to recover deleted data from your SQL server 2005 or above.( --Create Table Create Table [Test_Table] ( [Col_image] image, [Col_text] text, [Col_uniqueidentifier] uniqueidentifier, [Col_tinyint] tinyint, [Col_smallint] smallint, [Col_int] int, [Col_smalldatetime] smalldatetime, [Col_real] real, [Col_money] money, [Col_datetime] datetime, [Col_float] float, [Col_Int_sql_variant] sql_variant, [Col_numeric_sql_variant] sql_variant, [Col_varchar_sql_variant] sql_variant, [Col_uniqueidentifier_sql_variant] sql_variant, [Col_Date_sql_variant] sql_variant, [Col_varbinary_sql_variant] sql_variant, [Col_ntext] ntext, [Col_bit] bit, [Col_decimal] decimal(18,4), [Col_numeric] numeric(18,4), [Col_smallmoney] smallmoney, [Col_bigint] bigint, [Col_varbinary] varbinary(Max), [Col_varchar] varchar(Max), [Col_binary] binary(8), [Col_char] char, [Col_timestamp] timestamp, [Col_nvarchar] nvarchar(Max), [Col_nchar] nchar, [Col_xml] xml, [Col_sysname] sysname ) GO --Insert data into it INSERT INTO [Test_Table] ([Col_image] ,[Col_text] ,[Col_uniqueidentifier] ,[Col_tinyint] ,[Col_smallint] ,[Col_int] ,[Col_smalldatetime] ,[Col_real] ,[Col_money] ,[Col_datetime] ,[Col_float] ,[Col_Int_sql_variant] ,[Col_numeric_sql_variant] ,[Col_varchar_sql_variant] ,[Col_uniqueidentifier_sql_variant] ,[Col_Date_sql_variant] ,[Col_varbinary_sql_variant] ,[Col_ntext] ,[Col_bit] ,[Col_decimal] ,[Col_numeric] ,[Col_smallmoney] ,[Col_bigint] ,[Col_varbinary] ,[Col_varchar] ,[Col_binary] ,[Col_char] ,[Col_nvarchar] ,[Col_nchar] ,[Col_xml] ,[Col_sysname]) VALUES (CONVERT(IMAGE, REPLICATE('A',4000)) , REPLICATE('B',8000) , NEWID() ,10 ,20 ,3000 , GETDATE() ,4000 ,5000 ,getdate()+15 ,66666.6666 ,777777 ,88888.8888 , REPLICATE('C',8000) ,newid() ,getdate()+30 , CONVERT(VARBINARY(8000), REPLICATE('D',8000)) , REPLICATE('E',4000) ,1 ,99999.9999 ,10101.1111 ,1100 ,123456 , CONVERT(VARBINARY(MAX), REPLICATE('F',8000)) , REPLICATE('G',8000) ,0x4646464 ,'H' , REPLICATE('I',4000) ,'J' , CONVERT(XML, REPLICATE('K',4000)) , REPLICATE('L',100) ) GO --Delete the data Delete from Test_Table Go --Verify the data Select * from Test_Table Go --Recover the deleted data without date range EXEC Recover_Deleted_Data_Proc 'test','dbo.

To achieve this convert Null Bytes (Hex value) into Binary format (As discussed, 1 indicates null for the column and 0 means there is some data).

Here in this data, the Null Bitmap values are 00000111.
