According to MSDN  timestamp     Is a data type that exposes automatically generated  unique binary   numbers within a database  timestamp is generally used as a mechanism   for version-stamping table rows  The storage size is 8 bytes  The   timestamp data type is just an incrementing number and does not   preserve a date or a time  To record a date or time  use a datetime   data type    You re probably looking for the datetime data type instead

You can t insert the values into timestamp column explicitly  It is auto-generated  Do not use this column in your insert statement  Refer http   msdn microsoft com en-us library ms182776 SQL 90  aspx for more details   You could use a datetime instead of a timestamp like this   create table demo       ts datetime    insert into demo select current timestamp  select ts from demo   Returns   2014-04-04 09 20 01 153

How to insert current time into a timestamp with SQL Server  In newer versions of SQL Server  timestamp is renamed to RowVersion   Rightly so  because timestamp name is misleading  SQL Server s timestamp IS NOT set by the user and does not represent a date or a time   Timestamp is only good for making sure a row hasn t changed since it s been read  If you want to store a date or a time  do not use timestamp  you must use one of the other datatypes  like for example datetime  smalldatetime  date  time or DATETIME2 For example  create table wtf       id INT      leet timestamp    insert into wtf  id  values  15   select   from wtf  15    0x00000000000007D3    timestamp  in mssql is some kind of internal datatype   Casting that number to datetime produces a nonsense number

There is some good information in these answers  Suppose you are dealing with databases which you can t alter  and that you are copying data from one version of the table to another  or from the same table in one database to another  Suppose also that there are lots of columns  and you either need data from all the columns  or the columns which you don t need don t have default values  You need to write a query with all the column names   Here is a query which returns all the non-timestamp column names for a table  which you can cut and paste into your insert query  FYI  189 is the type ID for timestamp   declare  TableName nvarchar 50     Product    select stuff       select                 columns name     from           select id from sysobjects where xtype    U  and name    TableName  tables         inner join syscolumns columns on tables id   columns id     where columns xtype  lt  gt  189     for xml path       1  2        Just change the name of the table at the top from  Product  to your table name  The query will return a list of column names   ProductID  Name  ProductNumber  MakeFlag  FinishedGoodsFlag  Color  SafetyStockLevel  ReorderPoint  StandardCost  ListPrice  Size  SizeUnitMeasureCode  WeightUnitMeasureCode  Weight  DaysToManufacture  ProductLine  Class  Style  ProductSubcategoryID  ProductModelID  SellStartDate  SellEndDate  DiscontinuedDate  rowguid  ModifiedDate   If you are copying data from one database  DB1  to another database DB2  you could use this query   insert DB2 dbo Product  ProductID  Name  ProductNumber  MakeFlag  FinishedGoodsFlag  Color  SafetyStockLevel  ReorderPoint  StandardCost  ListPrice  Size  SizeUnitMeasureCode  WeightUnitMeasureCode  Weight  DaysToManufacture  ProductLine  Class  Style  ProductSubcategoryID  ProductModelID  SellStartDate  SellEndDate  DiscontinuedDate  rowguid  ModifiedDate  select ProductID  Name  ProductNumber  MakeFlag  FinishedGoodsFlag  Color  SafetyStockLevel  ReorderPoint  StandardCost  ListPrice  Size  SizeUnitMeasureCode  WeightUnitMeasureCode  Weight  DaysToManufacture  ProductLine  Class  Style  ProductSubcategoryID  ProductModelID  SellStartDate  SellEndDate  DiscontinuedDate  rowguid  ModifiedDate  from DB1 dbo Product

If you have a need to copy the exact same timestamp data  change the data type in the destination table from timestamp to binary 8  -- i used varbinary 8  and it worked fine   This obviously breaks any timestamp functionality in the destination table  so make sure you re ok with that first
