Build a SQL Query Builder

Builder pattern

Challenge 3 of Create & Share ObjectsIntermediate~55 minFree

Learn the Builder pattern by constructing a fluent SQL SELECT query builder. Each method records one clause and returns the builder itself, so calls chain into a readable pipeline. You will add SELECT and FROM, then WHERE, ORDER BY and LIMIT, prove the whole chain and a reset flow, and finish with a count_all preset - the exact machinery ORMs use to assemble SQL.
