class Sequel::SQL::PlaceholderLiteralString

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.

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.
