The relationship handler for groupwise maximum queries.
It allows a groupwise maximum of the linked in table. For a definition, see: http://dev.mysql.com/doc/refman/5.0/en/example-maximum-column-group-row… In lay terms, instead of joining to get all matching records in the linked table, we get only one record, a 'representative record' picked according to a given criteria.
Example: Suppose we have a term view that gives us the terms: Horse, Cat, Aardvark. We wish to show for each term the most recent node of that term. What we want is some kind of relationship from term to node. But a regular relationship will give us all the nodes for each term, giving the view multiple rows per term. What we want is just one representative node per term, the node that is the 'best' in some way: eg, the most recent, the most commented on, the first in alphabetical order.
This handler gives us that kind of relationship from term to node. The method of choosing the 'best' implemented with a sort that the user selects in the relationship settings.
So if we want our term view to show the most commented node for each term, add the relationship and in its options, pick the 'Comment count' sort.
Relationship definition
- 'outer field': The outer field to substitute into the correlated subquery. This must be the full field name, not the alias. Eg: 'term_data.tid'.
- 'argument table', 'argument field': These options define a views argument that the subquery must add to itself to filter by the main view. Example: the main view shows terms, this handler is being used to get to the nodes base table. Your argument must be 'term_node', 'tid', as this is the argument that should be added to a node view to filter on terms.
A note on performance: This relationship uses a correlated subquery, which is expensive. Subsequent versions of this handler could also implement the alternative way of doing this, with a join -- though this looks like it could be pretty messy to implement. This is also an expensive method, so providing both methods and allowing the user to choose which one works fastest for their data might be the best way. If your use of this relationship handler is likely to result in large data sets, you might want to consider storing statistics in a separate table, in the same way as node_comment_statistics.
