SQL Server 2012缺少RowVersion数据类型

Question

I recently restored my database onto a new SQL Server 2012 and notice that all my table columns of RowVersion data types have been changed to binary(8)

In Management Studio when I design the tables, the drop down for the data types no longer even has a choice for rowversion .

I cant find anything from MS other than old information that says it should still exist, or that it is equivalent to binary(8) however binary(8) doesn't auto generate a value like rowversion or timestamp .

Thanks

Answer 1

I haven't actually tried this but it should be something like:

ALTER TABLE YourTable
ALTER COLUMN YourCol rowversion

I think it's by design. Conversion to binary(8) means that any values generated so far are preserved but in order to carry on auto-generating, you need to convert back to rowversion using the above.
