how to fetch two same fields data from db [HTML5]? - sqlite

Question

this.db.transaction(function (tx)
{
tx.executeSql('SELECT tsk.*, cont.firstName, cont.lastName ,cont1.firstName, cont1.lastName, list.listId FROM tbl_tasks tsk, tbl_contacts cont,tbl_contactequests cont1, tbl_lists list WHERE (tsk.assignedId=0 or tsk.assignedId=cont.contactId or tsk.assignedId=cont1.contactRequestId) and tsk.taskCategoryType != "INBOX_NOT_ACCEPTED" and list.listId=tsk.listId and list.listId='+window.defaultlistid+' group by tsk.taskId', [], enyo.bind(this,this.queryResponse), enyo.bind(this,this.errorHandler));//call queryResponse
}.bind(this));
Now as you can see cont.firstName (Table tbl_contacts) & cont1.firstName has (Table tbl_contactequests) has same fields first name
for (var i = 0; i < len; i++)
{
list[i] = results.rows.item(i);
fname = list[i].firstName;
lname = list[i].lastName;
fullname = fname+' '+lname;
//alert(fullname);
if(list[i].assignedId==0)
{list[i].name = '';}
else
{list[i].name=fullname;}
}
with this loop i can able to featch first value of tbl_contacts field firstname.Now suppose if i can't to access tbl_contactequests table firstname.

Use AS keyword for SQL query:
'SELECT tsk.*,
cont.firstName AS cFirstName,
cont.lastName ,
cont1.firstName AS c1FirstName,
cont1.lastName, list.listId
FROM tbl_tasks tsk, tbl_contacts cont,
tbl_contactequests cont1, tbl_lists list
WHERE (tsk.assignedId=0 OR tsk.assignedId=cont.contactId OR
tsk.assignedId=cont1.contactRequestId) AND
tsk.taskCategoryType != "INBOX_NOT_ACCEPTED" AND
list.listId=tsk.listId AND list.listId='+window.defaultlistid+'
GROUP BY tsk.taskId'
