Overview

Json2sql — SQL builder that generates MySQL/MariaDB query strings from plain Ruby Hashes (or parsed JSON).

All Hash keys may be either Strings or Symbols; they are normalized to Strings internally before processing.

Entry points:

Json2sql::SelectRunner.build(hash) → String
Json2sql::InsertRunner.build(hash) → String
Json2sql::UpdateRunner.build(hash) → String
Json2sql::DeleteRunner.build(hash) → String

Defined Under Namespace
