Hi all. I have a content type with a cck integer field and I need to
increment it when user click on a link (user is redirect to another
page, or similar).

To do this I have two option:
1) node_save
2) db_query

This node type has a total of 5 cck fields. Other fields does not change
when user click on that link.
My site would be a trafficated site so I could have 10 or 100 clicks on
that link in a single moment.

I think to this code (for sql query solution):

db_query("LOCK TABLES {content_type_gf_product} WRITE,{watchdog} WRITE");
db_query("UPDATE {content_type_my_type} set field_download_stats_value
= field_download_stats_value+1 where nid = %d and vid = %d",
$node->nid,$node->vid);
db_query("UNLOCK TABLES");

Tnx.
