Class Sequel::SQL::PlaceholderLiteralString
In: lib/sequel/sql.rb
Parent: GenericExpression

Represents a literal string with placeholders and arguments. This is necessary to ensure delayed literalization of the arguments required for the prepared statement support and for database-specific literalization.

Methods

new  

Attributes

args  [R]  The arguments that will be subsituted into the placeholders. Either an array of unnamed placeholders (which will be substituted in order for ? characters), or a hash of named placeholders (which will be substituted for :key phrases).
parens  [R]  Whether to surround the expression with parantheses
str  [R]  The literal string containing placeholders. This can also be an array of strings, where each arg in args goes between the string elements.

Public Class methods
