Module: SQLite3::Pragmas

Included in:
Database
Defined in:
lib/sqlite3/pragmas.rb

Overview

This module is intended for inclusion solely by the Database class. It defines convenience methods for the various pragmas supported by SQLite3.

For a detailed description of these pragmas, see the SQLite3 documentation at sqlite.org/pragma.html.
