cast or convert varchar datatype to rowversion

Question

I am able to convert rowversion column in a table to varchar using below code

select CONVERT(VARCHAR, CONVERT(BINARY(8), roversion_col), 1) rwa from TBL

How do I convert it back to rowversion datatype? Is it NOT possible to do so?

Update:
This should not be treated as duplicate with How to convert TIMESTAMP values to VARCHAR in T-SQL as SSMS does?

That question is about asking rowversion datatype to varchar. However, this question is vice-versa and wanted to get rowversion data using varchar.

Answer 1

Try this:

CONVERT(rowversion, CONVERT(BINARY(8), @teststring, 1))
