Async

Async execution of SQL statements

Using alasql will normally be sync

    var result = alasql(sql [, params])

However, AlaSQL will always run async in the following cases.

• If using AlaSQL as a WebWorker
• All operations involving IndexedDB
• INTO-functions (for example SELECT * INTO CSV(...))
• FROM-functions (for example SELECT * FROM CSV(...))

We strongly recommend using the promise notation:

alasql.promise(sql [, params])
      .then(function(data){
           console.log(data);
      }).catch(function(err){
           console.log('Error:', err);
      });

If you feel very confident that you do not need to handle errors you can run async by add a 3rd parameter to alasql with a callback function:

	alasql(sql, params, function(data) {
		// do something with data
	});

Note that if you have no params the value must be set to []

Example:

     var resSync = alasql('SELECT * FROM CSV("mydata.csv")',[],function(data){
          console.log(data);
     });
