Hello, I'm Maneshwar. I'm building git-lrc, an AI code reviewer that runs on every commit. It is free, unlimited, and source-available on Github. Star Us to help devs discover the project. Do give it a try and share your feedback for improving the product. Now that the internal structures and their interconnections are clear, the final piece is understanding how an application actually drives all of this through the SQLite API. It starts with a simple call: sqlite3_open. When this function is invoked successfully, SQLite allocates a sqlite3 object in the application’s memory space. At this point, the connection is initialized, but it is still idle, no SQL has been compiled yet, and the pVdbe list (which holds compiled statements) is empty. From SQL Text to Bytecode The moment an application prepares a query using sqlite3_prepare, SQLite translates the SQL text into a compiled representation. Internally, this creates a Vdbe object, which is essentially a bytecode program ready to be exe
