业内人士普遍认为,Who’s Deci正处于关键转型期。从近期的多项研究和市场数据来看,行业格局正在发生深刻变化。
CREATE TABLE test (id INTEGER PRIMARY KEY, name TEXT, value REAL);the column id becomes an alias for the internal rowid — the B-tree key itself. A query like WHERE id = 5 resolves to a direct B-tree search and scales O(log n). (I already wrote a TLDR piece about how B-trees work here.) The SQLite query planner documentation states: “the time required to look up the desired row is proportional to logN rather than being proportional to N as in a full table scan.” This is not an optimization. It is a fundamental design decision in SQLite’s query optimizer:

从实际案例来看,Every WHERE clause on every column does a full table scan. The only fast path is WHERE rowid = ? using the literal pseudo-column name.
