"Update temporary item data" required if i unpublish item by changing it state to -2 in database

Hi,
i'm working on a script that unpublished item by items id.
For a items id in array, a make a sql request to unpublish this item by setting "state" to -2 in jos_content.

In items list, i can see the item with the trash icon, but i don't need to filter by state to see it. After logout/login again, FC dashboard ask me to " Update temporary item data", and then everyting is back to normal : item is trashed and i need to filter by trashed state to see trashed items.

How can i udpate temporary data at the end of my script ? Or do I need to update any FC table to achieve this without updating temporary datas ?

[Edit] Items with state set to -2 still show in front (unlogged) until i refresh temporary datas

Found that I had to update 'jos_flexicontent_items_tmp' too, now everything works fine.
Is there a better method or class to call to achieve this in a cleaner way?

i think update 2 table in same way
