Postgres schema definition, sql/go, code generation package.
entity - struct that reflects single row within the databasecriteria - object that can be passed to the Find method, it allows to create complex queriespatch - structure used by UpdateBy<primary-key> methods to modify existing entityiterator - structure used by FindIter methods as a result, it wraps sql.Rows
constants:
table names
column names
constraints - library generates exact names of each constraint and corresponding constant that allow to easily handle query errors using ErrorConstraint helper functionrepository - data access layer that expose API to manipulate entities:
Count - returns number of entities for given criteriaFind - returns collection of entities that match given criteriaFindIter - works like Find but returns iterator
Insert - saves given entity into the databaseFindOneBy<primary-key> - retrieves single entityUpdateBy<primary-key> - modifies single entityDeleteBy<primary-key> - modifies single entityfunc Scan<Entity>Rows(rows *sql.Rows) ([]*<entity>Entity, error) { helper functionschemas
