What is the best way to style Query Builder?

Question

PHP

I am writing my bicycle framework. It is necessary to make a universal class of queries to the database, or rather to a table in the database. That is one class - one table. Preferably this should be able to send MySQL, PostgreSQL, MSSQL and SQLite queries. Well, the implementation is based on PDO, one problem is Query Builder. How best to implement it?

Answer 1

I don’t know about you, but here, starting from the university, they said: before you rush to realize your own, you must first study what is already there. At least that's how you get smart ideas.
Look at the existing implementations of the query builder --- there will be ideas on how to implement your bike.
