* {Matches,DoesNotMatch} support the ESCAPE clause with PostgreSQLKazuya NUMATA2014-12-251-0/+14
| | | | | to_SQL already has supported the ESCAPE clause in #318. PostgreSQL can use the ESCAPE clause too.
* Remove `engine` from `TreeManager` and subclassesSean Griffin2014-11-291-1/+1
| | | | | | This constructor parameter was unused for everything except the convenience methods `to_sql` and `where_sql`. We can pass the engine into those methods directly.
* Remove deprecated method "Table#primary_key"Sean Griffin2014-11-261-0/+19
| | | | | | | The only place this method was still used is on the MSSQL visitor. The visitor has all of the objects required to inline this lookup there. Since the `primary_key` method on the connection adapter will perform a query when called, we can cache the result on the visitor.

* Use class objects rather than strings for the dispatch cacheSean Griffin2014-11-181-1/+1
| | | | | | | | The only reason we're using strings is to pre-populate the cache, but `Class#name` returns a new string instance on every call. This is a pretty major source of memory usage. We don't technically need to pre-populate the cache, and not doing so allows us to go back to using cache objects
* Add order to BindParams in the ToSql collectorSean Griffin2014-11-173-4/+21
| | | | | | | | | | | | This removes the need for us to do the re-ordering by walking the AST in ActiveRecord. We're using a block to communicate with the collector, since the collector needs to be the thing which knows about the index, while the visitor is the thing that needs to know the syntax. The BindParam needs to know about neither of these things, so it's been changed to stop being a subclass of SqlLiteral I could also see an alternative implementation using format strings if for some reason blocks cause a problem.
* Deprecate passing ranges to `#in` and `#not_in`Sean Griffin2014-10-251-12/+12
| | | | | | | The goal of these methods should be to generate in nodes, not handle every possible permutation of more than one value. The `#between` and `#not_between` methods have been extracted, which better represent the semantics of handling ranges in SQL.
* `#not_in` with a range should respect proper precedenceSean Griffin2014-10-241-6/+6
| | | | | | | | | | | | | | | | | | Currently, doing ```ruby relation[:id].not_eq(4).and(relation[:id].not_in(1..3)) ``` will generate ```sql "id" != 4 AND "id" < 1 OR "id" > 3 ``` Which would incorrectly include records with an id of 4, as the OR statement has higher precidence than the AND statement. The `or` method on `Node` properly groups the statement in parenthesis.

* move the dispatch table to be per-instanceAaron Patterson2014-09-222-7/+1
| | | | | | | visitors are not shared among threads, so any mutations to the cache should be OK. The cache is also pre-populated on construction, but we should pull that out so we can share the cache among visitors in the future.

* | Test quoting integers when comparing a string column with integers.Dylan Smith2014-04-281-2/+14
| | | | | | | | | | | | | | | | | | | | An equality with a string column and integer like SELECT * FROM `users` WHERE `login_token` = 0 LIMIT 1; will match match any string that doesn't start with a digit in certain databases, like mysql. Make sure we quote the integer to avoid this problem in a database independant way.
