Update previous versions in DFS

Hello all.
I'm trying to update properties in previous version of document by using objectService.Update (I'm using c#) and i've got an exception.
In the DFS_Dev_Guide, it was mentioned that Update operation will only update the CURRENT version of an object.

How can I update non-current versions?

Thanks,
MTs

Hi,

You could use QueryService:

update dm_document (all) object where r_object_id='...'

Thanks Miklos.

Your answer was very helpful.

I want to update repeated attribute in all versions.

I want to replace one value with other value.

Example:

I have this repeated attribute:

author = authorName1, authorName2, authorName3.

I want to replace authorName2 with authorName5, so I'll get new list:

author = authorName1, authorName5, authorName3.

I know i can insert the value to the specific index like:

Update dm_document objects insert author[1] = authorName5 where ...

But, the problem is that I want to update this in all versions, and probably the value in index 1 in one version will be different from the value in index 1 in other version.

Example:

Version 1 : author = authorName1, authorName2, authorName3.

Version 1.1 : author = authorName3, authorName1, authorName2.

The value in index 1 (author [1]) is different.

Can I update repeated attribute by value?

Hope I expressed my question clearly,

MTs.

Hi,

I don't think you can do that. Just read Content Server DQL guide "Repeating attributes in queries" section. You can update objects' repeating attributes, (replace a value) but only when you know it's index position. I don't have any experience how to do this effectively.

For a single attribute it would be easy:

update dm_document (all) objects set title='example' where i_chronicle_id='r_object_id of the 1.0 version'

Anyway, if you want to update a non-current version's attribute, the attribute must be non-immutable.

and don't forget that non CURRENT versions of a document as immutable so 1st you'll need to the the immutable attribute to false, save the object, then do your properties modifications and at last, reset the immutable attribute to true
