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.
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. |
Create an object with the given string, placeholder arguments, and parens flag.
