Convert varchar to timestamp in SQL Server 2008 R2 -


there table timestamp column in sql server 2008 r2. when add column table see values 0x00000000000007d1. try put data it:

update test_time set date3= convert(timestamp, convert(datetime,'2002-08-20 14:00:00.000',120)) ogr_fid=1

but error

cannot update timestamp column

what's wrong here?

sql server's timestamp datatype has nothing date , time!

it's binary representation of consecutive number - it's making sure row hasn't change since it's been read.

in never versions of sql server, it's being called rowversion - since that's is. see msdn docs on rowversion:

is data type exposes automatically generated, unique binary numbers within database. rowversion used mechanism version-stamping table rows. rowversion data type just incrementing number , not preserve date or time. record date or time, use datetime2 data type.

so cannot convert string timestamp in sql server.
