nodejs与sqlite

//打开数据库

var db = new sqlite3.Database('xx.db');

// 关闭数据库

db.close();

db.run('xx'); // 数据库对象的run函数可以执行任何的SQL语句，该函数一般不用来执行查询

// create alter 之类的

增:

var stmt = db.prepare("INSERT OR REPLACE INTO note (cdate, content) VALUES (?,?)");

stmt.run(data.cdate, data.content);

stmt.finalize();

删:

db.prepare("DELETE from note where cdate =?");

stmt.run(data.cdate);

stmt.finalize();

改:

var stmt = db.prepare("UPDATE note set content=? where cdate =?");

stmt.run(data.content, data.cdate);

stmt.finalize();

查:

db.each("SELECT rowid AS id, thing FROM Stuff", function(err, row) {

console.log(row.id + ": " + row.thing);

});

});

// or

db.all("SELECT xxx", function (err, res){});

// 使用

先把库下载到node_modules npm install sqlite3 --save

1.引入sqlite3库

var sqlite3 = require('sqlite3');

// or var sqlite3 = require("sqlite3").verbose();

var db = new sqlite3.Database(file);

db.serialize(function() {

//Do stuff...

db.run("CREATE TABLE Stuff (thing TEXT)");

var stmt = db.prepare("INSERT INTO Stuff VALUES (?)");

for(var i = 0;i<xx;i++){

stmt.run('xx');

}

stmt.finalize();

});

db.close();
