# File lib/sequel/extensions/ruby18_symbol_extensions.rb, line 19 19: def [](*args) 20: Sequel::SQL::Function.new(self, *args) 21: end
Returns receiver wrapped in an Sequel::SQL::Identifier. Usually used to prevent splitting the symbol.
:a__b # SQL: "a"."b" :a__b.identifier # SQL: "a__b"
# File lib/sequel/extensions/core_extensions.rb, line 215 215: def identifier 216: Sequel::SQL::Identifier.new(self) 217: end
Returns a Sequel::SQL::Function with this as the function name, and the given arguments. This is aliased as Symbol#[] if the RUBY_VERSION is less than 1.9.0. Ruby 1.9 defines Symbol#[], and Sequel doesn‘t override methods defined by ruby itself.
:now.sql_function # SQL: now() :sum.sql_function(:a) # SQL: sum(a) :concat.sql_function(:a, :b) # SQL: concat(a, b)
