2013-05-14join and rename preconditions removing ambiguity, `on` now optional...`join` and `rename` both had the ability to introduce some ambiguity, whether by renaming two fields to the same alias (which one should use that alias?) or by joining two fields with the same alias (which one should use it?). Some preconditions have been added to warn against some ambiguous use cases (although I have just now realised the rename precondition is insufficient, so a new commit will be coming soon).

2013-05-14Parametrise deref behaviour, add two small tests....Now a user can decide what the query's behaviour on deref should be. This means a user using jdbc can plug in with (set-query-deref-behaviour! #(... jdbc-query-code-here ...)) if they want, but if a user wants to use the code for something else then they can do so without needing to import jdbc stuff. (I'll admit I'm not sure what else they'd do with it, but that's slightly beside the point.) Still left to do is to provide a helper for the common case (performing an SQL query with jdbc).

2013-05-14Apparently I got the jdbc query syntax wrong. Corrected....The parameters should be passed in the `rest` of the vector, not as a separate seq. My bad. Carlo Zancanaro
2013-05-14Fix up the README (example code)Carlo Zancanaro
2013-05-14Fix ordering issue, split out string parameters for jdbc stuff...The string parameters are now put in the query as a '?' and the string which should go in their place is now placed in an auxiliary list when the query is constructed. This should make it easier to avoid SQL injection stuff. (Although table/column names are still vulnerable to SQL injection, they should not be dynamic so the issue should be minimal.) There was also another issue where some things were used before they were declared (as a result of repl development) which has now been corrected. Carlo Zancanaro
2013-05-14Most of the RA stuff works now....Need to fix up the compilation to return a query ready for value substitution by the jdbc stuff, or something (rather than embedding parameters in the query). Also need to add insert!, update! and delete! functions. Carlo Zancanaro
