It is not obvious what and where is going on. Here is my proposal, while it
is a bit tricky too :-)
Have not tested if it works actually
function() {
var tr, st;
function error(err) {
if (tr) tr.rollback();
if (st) st.drop();
console.log(err);
}
function fetchByOne(onData,onEnd,error)
{
database.startTransaction(function(transaction) {
tr = transaction;
tr.newStatement("select * from rdb$relations", function(statement) {
st = statement;
st.execute(tr, function() {
(function cb(fetched) {
if (fetched) {
st.drop();
tr.commit(); // fetch finished
onEnd();
} else {
st.fetch(tr, function(ret) {
onData(ret.data); // fetch is going on
cb(ret.fetched);
}, error)
}
})(false);
}, error)
}, error);
}, error)
}
fetchByOne(function(data){
console.log(data);
},
function(){
console.log(finished);
},error);
