# The from_block extension changes Database#from so that blocks given
# to it are treated as virtual rows applying to the FROM clause,
# instead of virtual rows applying to the WHERE clause. This will
# probably be made the default in the next major version of Sequel.
#
# This makes it easier to use table returning functions:
#
# DB.from{table_function(1)}
# # SELECT * FROM table_function(1)
#
# To load the extension into the database:
#
# DB.extension :from_block
#
module Sequel
module Database::FromBlock
# If a block is given, make it affect the FROM clause:
# DB.from{table_function(1)}
# # SELECT * FROM table_function(1)
def from(*args, &block)
if block
@default_dataset.from(*args, &block)
