The get is not waiting to perform a call so you need to do a callback in your get function to perform the next one. You could do something like this:
var index = -1;
function perform_get(){
index++;
var url = "http://172.25.129.30:8180/prax/rest/ocorrenciaJSONBean/consultarStatusOcorrencia/"+results.rows.item(index).id;
$.get(url,function(data){
tx.executeSql('UPDATE ocorrencias SET status="'+data.responseText+'" WHERE id = '+results.rows.item(index).id);
})
.done(perform_get);
}
Now it is waiting to perform the next get call.
Hope this helps.
