Public Instance methods

identifier_input_method=(v)

Set the method to call on identifiers going into the database:

  DB[:items] # SELECT * FROM items
  DB.identifier_input_method = :upcase
  DB[:items] # SELECT * FROM ITEMS

66:         reset_default_dataset
67:         @identifier_input_method = v
68:       end

identifier_output_method=(v)

Set the method to call on identifiers coming from the database:

  DB[:items].first # {:id=>1, :name=>'foo'}
  DB.identifier_output_method = :upcase
  DB[:items].first # {:ID=>1, :NAME=>'foo'}

77:         @identifier_output_method = v
78:       end

quote_identifiers=(v)

Set whether to quote identifiers (columns and tables) for this database:

  DB[:items] # SELECT * FROM items
  DB.quote_identifiers = true
