|
* adding limit options to update and destroyNick Kallen2008-04-132-2/+4
|
* fixed problem with updating multiple valuesNick Kallen2008-04-131-1/+1
|
* implementing one pending featureNick Kallen2008-04-131-2/+2
|
* new conception of grouping and aggregation functionalityNick Kallen2008-04-137-37/+36
|
* adjacency lists workNick Kallen2008-04-132-3/+27
| | | | - implementation is a bit complex, but i can't think of anything simpler
* better test coverage of relational operations with blank dataNick Kallen2008-04-123-35/+6
|
* added pending test for (difficult) problem of aliasing tables for adjacency ↵Nick Kallen2008-04-121-2/+2
| | | | lists
* - removed #qualify and #descend helperNick Kallen2008-04-1215-75/+3
| | | | | - qualify seems no longer neccessary since everything is fully qualified - finished pending specs
* - string passthrough for joinsNick Kallen2008-04-125-16/+22
| | | | - blank checks
* fixed bug with take/skipNick Kallen2008-04-114-16/+16
|
* redesigned the way limit and offset workNick Kallen2008-04-116-35/+52
| | | | - was range now have special 'take' and 'skip' operations. (the terminology comes from linq)
* string passthrough for joinsNick Kallen2008-04-112-1/+13
|
* string passthrough for joinsNick Kallen2008-04-115-5/+11
|
* removed binding for attributes and predicatesNick Kallen2008-04-112-8/+8
|
* removed bind for insertion and updationNick Kallen2008-04-113-4/+4
|
* refactored bind for orderNick Kallen2008-04-112-2/+3
|
* moved bind to factory of selectNick Kallen2008-04-113-17/+8
|
* added attribute.eq(nil)Nick Kallen2008-03-168-7/+19
| | | | - produces attribute IS NULL
* projections now support string passthroughNick Kallen2008-03-162-3/+7
| | | | - there is a weird inconsistency in where bind is called on values; this needs to be resolved
* nested orderingsNick Kallen2008-03-165-14/+10
|
* allowing string passthrough for order clausesNick Kallen2008-03-163-14/+23
|
* added support for `attribute IN ...` and `attribute BETWEEN ...`Nick Kallen2008-03-168-25/+44
| | | | | - IN and BETWEEN are chosen depending on the type of the second operand - ranges (1..2), arrays ([1,2,3]), and relations ("SELECT * ...") are all supported
* renamed operatorsNick Kallen2008-03-161-5/+5
| | | | | | - equals / eq - greater_than / gt - etc.
* formatting insert and update statementsNick Kallen2008-03-164-14/+6
| | | | - values need to be coerced to the type corresponding to the column
* renamed strategy to formatterNick Kallen2008-03-1611-18/+18
|
* properly quoting array valuesNick Kallen2008-03-1611-22/+39
|
* js/nk - fixed hashingNick Kallen2008-03-152-3/+5
|
* annotated abstract methods on relationNick Kallen2008-03-132-6/+16
|
* annotated abstractionNick Kallen2008-03-136-5/+9
| | | | | - in compound - created superclass for the create/insert/update write operations, marked :call as abstract
* added abstract declarationNick Kallen2008-03-135-10/+22
|
* renamed sql formatting strategies to correspond with sql grammar rule names ↵Nick Kallen2008-03-135-26/+25
| | | | in the mysql bnf
* - renamed scalar to valueNick Kallen2008-03-125-13/+13
| | | | - added better test coverage and documentation of binary spec #to_sql
* renamed strategy method to formatNick Kallen2008-03-115-15/+19
| | | | | | - strategy (the method on scalar and attribute) is a complex double-dispatching scheme to format (to_sql) a scalar in the light of the particular attribute; that is, it casts strings to integers if the column is int, etc.
* refactored session's interaction with engine/connectionNick Kallen2008-03-115-4/+20
| | | | | - follows law of demeter - Table.engine uses AR::Base adapter
* implemented hashing macro; implemented custom matcher testing this macroNick Kallen2008-03-115-10/+11
|
* basic functionality for simplest active record find(id)Nick Kallen2008-03-052-11/+25
| | | | - messy code, to be cleaned up this weekend
* scalars are now lifted; the heavy lifting is done by the operations on ↵Nick Kallen2008-03-0213-48/+70
| | | | relation (select, join, etc.)
* introduced engine dependency for sql strategiesNick Kallen2008-03-0212-33/+43
| | | | - hacked in default engine for scalars -- BAD
* new concept of session boundariesNick Kallen2008-03-028-17/+53
|
* quoting issuesNick Kallen2008-02-2411-70/+58
|
* renamed attribute to operand per josh's suggestionNick Kallen2008-02-241-12/+13
|
* Introduced concept of session. It does not yet support multiple databases, ↵Nick Kallen2008-02-237-27/+89
| | | | nor transactions, but it's a start!
* updating functionalityNick Kallen2008-02-231-0/+17
|
* added primitive update functionalityNick Kallen2008-02-231-0/+1
|
* extracted conditionals concerning the "externalizing" of relations under a join.Nick Kallen2008-02-185-18/+44
|
* made descend public; added test coverage for it; tests for qualify are now ↵Nick Kallen2008-02-189-16/+8
| | | | in terms of descend
* rename __collect__ to descend since the double underscores were ugly.Nick Kallen2008-02-1811-22/+22
|
* adding support for scalar selectsNick Kallen2008-02-161-2/+2
|
* introduced __collect__, an internal enumerating operator. This is a map down ↵Nick Kallen2008-02-1613-34/+61
| | | | the tree representing the relation. Monadic map to be precise
