Consecutive and sequence insert in node.js sqlite

Question

my code is:

 var json = [1,2,3,4,5,6,7,8,9];
 async.forEach(json, function (that, callback) {
      sqlitedb.run("INSERT INTO mytable (name) VALUES ("+that+")" , function () {
           console.log(that); callback();
      });
 });

The callback() placed on after insert item. but when i execute, my json items inserted on no squence and result is like:

Can anyone help me. Thanks.

Note that queries without an ORDER BY clause aren't guaranteed to have any particular ordering anyway. — Colonel Thirty Two

You have to use async.eachSeries:

forEach will execute in parallel.

async.eachSeries(json, function (that, callback) {
      sqlitedb.run("INSERT INTO mytable (name) VALUES ("+that+")" , function () {
           console.log(that); callback();
      });
 });
