Here is databaseworker.js:
var wp = google.gears.workerPool;
wp.allowCrossOrigin();
wp.onerror = function(errorObject)
{
alert("Error in workerPool: "+errorObject.message+" on
line"+errorObject.lineNumber);
};
wp.onmessage = function(a, b, message)
{
wp.sendMessage("Ok, started....",message.sender);
var serverresponse= message.body;
if (1)
{
try
{
eval("dataarr="+serverresponse);
wp.sendMessage("Error: No valid data found. Data
was:"+serverresponse,message.sender);
}
catch (ex)
{
wp.sendMessage(ex.message,message.sender);
//wp.sendMessage("Error: No valid data found..",message.sender);
//alert("Error: No valid data found..");
return;
}
var dbcount=0;
var reply="no reply";
var db ;
db= google.gears.factory.create('beta.database');
if (db)
{
db.open('tml_impact_gears');
db.execute('begin');
db.execute('drop table if exists orders');
db.execute('create table if not exists orders' +
'(order_id, order_no,
order_no_iteration,estimated_completion_date, other_contact_tel, primary key
(order_id))');
for (x in dataarr)
{
db.execute('insert into orders values(?,?,?,?,?)',
[dataarr[x].order_id,
dataarr[x].order_no,
dataarr[x].order_no_iteration,
dataarr[x].estimated_completion_date,
dataarr[x].other_contact_tel]);
dbcount++;
}
}
db.execute('commit');
db.close();
reply=dbcount+" record(s) added from main DB, finished"; }
wp.sendMessage(reply, message.sender);
};
Thanks for looking at it.
