class Sequel::SQL::Blob

  1. lib/sequel/sql.rb
Superclass: String

Blob is used to represent binary data in the Ruby environment that is stored as a blob type in the database. Sequel represents binary data as a Blob object because most database engines require binary data to be escaped differently than regular strings.

1044   content = if size > 20
1045     "start=#{self[0...10].to_s.inspect} end=#{self[-10..-1].to_s.inspect}"

lit(*args)

Return a LiteralString with the same content if no args are given, otherwise return a SQL::PlaceholderLiteralString with the current string and the given args.
