nodejs與sqlite

//打開數據庫
var db = new sqlite3.Database('xx.db');

// 關閉數據庫
db.close();

db.run('xx');  // 數據庫對象的run函數可以執行任何的SQL語句，該函數一般不用來執行查詢
               // create alter 之類的


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

刪:
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

先把庫下載到node_modules  npm install sqlite3 --save

 1.引入sqlite3庫
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();
