* Skip query cache for in_batches and friendsEugene Kenny2017-07-061-0/+42
| | | | | | | | | | | The `find_each`, `find_in_batches` and `in_batches` APIs usually operate on large numbers of records, where it's preferable not to load them all into memory at once. If the query cache is enabled, it will hold onto the query results until the end of the execution context (request/job), which means the memory used is still proportional to the total number of records. These queries are typically not repeated, so the query cache isn't desirable here.

| * Remove delegating to arel in a relationRyuta Kamizono2017-06-291-1/+1
| | | | | | | | | | The delegation was needed since passing `relation` with `relation.bound_attributes`. It should use `relation.arel` in that case.

* Fix where_clause#except with specific where valueJohn Hawthorn2017-03-201-0/+8
| | | | | | | | | Fixes a regression introduced in 22ca710f20c3c656811df006cbf1f4dbc359f7a6 where Relation#unscope with a specific where value (vs unscoping the entire where clause) could result in the wrong binds being left on the query. This was caused by an index variable not being incremented properly.
* Use `load` rather than `collect` for force loadingRyuta Kamizono2017-03-191-7/+7
| | | | | | | Since b644964b `ActiveRecord::Relation` includes `Enumerable` so delegating `collect`, `all?`, and `include?` are also unneeded. `collect` without block returns `Enumerable` without preloading by that. We should use `load` rather than `collect` for force loading.
* Allow order to be given expressions as hash keysEugene Kenny2017-02-271-1/+24
| | | | | | | | | | | | | When `order` is given a hash, the keys are currently assumed to be attribute names and are quoted as such in the query, which makes it impossible to pass an expression instead: Post.order("LENGTH(title)" => :asc).last # SELECT `posts`.* FROM `posts` ORDER BY `posts`.`LENGTH(title)` DESC LIMIT 1 If the key is an `Arel::Nodes::SqlLiteral`, we now use it directly in the query. This provides a way to build a relation with a complex order clause that can still be reversed with `reverse_order` or `last`.

* Respect new records for `CollectionProxy#uniq`Ryuta Kamizono2016-11-131-1/+0
| | | | | | | | | | | | | Currently if `CollectionProxy` has more than one new record, `CollectionProxy#uniq` result is incorrect. And `CollectionProxy#uniq` was aliased to `distinct` in a1bb6c8b06db. But the `uniq` method and the `SELECT DISTINCT` method are different methods. The doc in `CollectionProxy` is for the `SELECT DISTINCT` method, not for the `uniq` method. Therefore, reverting the alias in `CollectionProxy` to fix the inconsistency and to have the both methods.

* | Allow the connection adapters to determine the order of bind paramsSean Griffin2016-05-061-0/+18
|/ | | | | | | | | | | | In 5.0 we use bind parameters for limit and offset, while in 4.2 we used the values directly. The code as it was written assumed that limit and offset worked as `LIMIT ? OFFSET ?`. Both Oracle and SQL Server have a different syntax, where the offset is stated before the limit. We delegate this behavior to the connection adapter so that these adapters are able to determine how the bind parameters are flattened based on what order their specification has the various clauses appear.
