better-sqlite3 is a powerful and high-performance Node.js library for interacting with SQLite databases. It focuses on providing an easy-to-use, synchronous API that supports both simplicity and performance. Unlike other SQLite libraries for Node.js, such as sqlite3, better-sqlite3 eliminates the...
prepare('INSERT INTO users (name, email) VALUES (?, ?)'); stmt.run('Charlie', 'charlie@example.com'); stmt.finalize(); } catch (error) { console.error('数据库操作失败:', error); } 通过以上步骤,你就可以在Electron项目中成功使用better-sqlite3库来进行SQLite数据库操作了。希望这些信息...
In most cases, if you're attempting something that cannot be reasonably accomplished withbetter-sqlite3, it probably cannot be reasonably accomplished with SQLite in general. For example, if you're executing queries that take one second to complete, and you expect to have many concurrent users ...

For example, if you're executing queries that take one second to complete, and you expect to have many concurrent users executing those queries, no amount of asynchronicity will save you from SQLite3's serialized nature. Fortunately, SQLite3 is very very fast. With proper indexing, we've ...
Below is an example of mixing anonymous parameters with named parameters.const stmt = db.prepare('INSERT INTO people VALUES (@name, @name, ?)'); stmt.run(45, { name: 'Henry' });Here is how better-sqlite3 converts values between SQLite and JavaScript:...
