Optimizing Asp Database Calls

I'm very interested in finding out what ways you experts out there have made your data dips more efficient in your asp (not asp.net) code.

I have a wizard-type application that dips into the database with each page, I know there's a better way to do this out there, just pressed for time and can't think right now.

Database Calls Made

Is there a way I can see how many database calls were made from my script to the db server to check how well my SQL queries are formed?

I get the time taken to execute the queries, but in that time taken, I want to know how many calls were made to the DB server. Is it possible?

Database - Recursive Function Calls

..:: The Specs:

MS Access 2000 (host charges extra for SQL/MySQL)
MS Windows Server 2003 (prod) / MS XP SP1 (dev)

..:: The setup:

The database has been setup with two tables;

tblDownloads
tblCatagories

Each "download" consists of a catagory field that corresponds to fldID in
tblCatagories. Each catagory, where the catagory is a parent, has a parent
field of value: 0 and each child, has a field with a value corresponding to
the fldID of it's parent. Code:

Database Calls, Server Transfers, Sessions, And Cookies

Any body know of a resource that compares/benchmarks the expense (in terms of milli seconds, or server load) of using various programing options?

I know a lot of articles and forum posts reccomend best practices between functions and programming options, but I would be interested in some type of definitive benchmark to decide between various prgramming options, depending on the need.

For example, I can call a Recordset and quickly write it into an array, so that the connection can be closed even before I write the data to the HTML page. This would save conection time and server resources, but I'd like to be able to judge the worth when considering coding it.

Every time I do a Server.Transfer how expensive is it to the server? How much am I loading the server with Session varaibles? If I store some info in a cookie, but have to call it, how long will that take? Am I using up server resources by creating large arrays?

Optimizing Code On ASP Page

We have a report page which deals with more than 3000 records and 80 columns. The records are displayed on a third party control VS flexgrid versioned 7.0.

Currently we are having a client side array populated from the server side using response.write . Is there any other means to optimize the performance on this page?

Optimizing - Large Db Result Set

when creating a webpage that must display a large result set, the page load time is unbearable. Unfortunately, there are a lot of records and they all need to be displayed, at once, on this one page.

To reduce file size, I have minimized the amount of HTML tags used to dislay these records. My only other idea is to write javascript matrix to hold the data, and then to use dom to create the page on the client side. Are there any tried and true ways of speeding up page loads?

Optimizing Multidimensional Array Code

I have a multidimensional array that is actually 1 dimension (it comes from a recordset.getrows that returns 1 column). My goal is to put every single line of the recordset in a textfile. currently, here is my code Code:

for i = 0 to UBound(Res,2)
fileContent = fileContent & res(0,i))
Next
createTxtFile(path,fileContent)

I have 5000 lines and it takes about 10 minutes. I was thinking of doing a Array.Join but I don't think that works with multidimentional array. Also thinking of converting my useless multidimentional array into a sing dimensional array but how?

Recursive Calls

I have implemented a logic for my requirement with a recursive call. The logic is I need to get IDs from database for a scenario. There are corresponding records for each ID.

I need to store these IDs in an array variable. Then I need to get (dependent)IDs for the fields in each ID. There may be morethan one dependent per each ID. I append these IDs to my array. Like this it goes.

The problem is if there are many levels like this, the number of database cursor count is reaching to maximum and I'm getting the error

{Microsoft OLE DB Provider for ODBC Drivers error '80004005'
[Microsoft][ODBC driver for Oracle][Oracle]ORA-00604: error occurred at recursive SQL level 1 ORA-01000: maximum open cursors exceeded }

each recursive call runs a SELECT query.

Can any one suggest me an alternate solution for this ?

Function Calls

I'm terribly sorry if this has been asked before, but I need a clear explenation without having to sift through other bits of information.

Can somone explain how functions work in asp (not asp.net)? I need to call a function that returns a value, and I get an error when I have a return statement in there. If there is no "return" statement, then what do you use to get this value back?

How To Use IIS To Redirect Http Calls?

I need to implement an application that receives http calls from a remote
client, do something with it and returns some feedback. I want to use IIS
(version 6) as my front end http server (with https and ssl services) which
will facilitate all the requirements of a http server and then foreword the
incoming call to my application and will return the process result to the
client at the end.

Does IIS support this? And if yes - what are the requirement from my application to use it (built in .net if anyone interested)?

Session Storage Vs. Frequent DB Calls

I'm developing web surveys where users logon to a web survey and answer up
to about 50 questions, one after the other, shown only one question at a
time. The answers are saved in a database.

A fellow developer and I are discussing when is the best time to save the
answers. We have two approaches in mind:

Approach 1:
After each question is answered, the answer is saved in the database.
Sessions are only used to store the User ID.

Approach 2:
After each question is answered, the answer is saved in a session variable.
When the user has finished the entire survey, all the answers are saved at
once in the database. Also, if the user logs out, or if the session times
out, the answers answered so far are all saved in the database at once.

The amount of actual data sent to the database is the same in both
approaches, but Approach 1 have much more frequent calls to the DB, thus
creating an overhead of opening and closing connections. I'm not sure how
significant that is. On the oter hand, Approach 2 store a lot of data in
sessions. I'm not sure how bad a thing that is.

Which approach is better and for what reasons? I'd be happy to supply more
information if needed.

Correlate ASP Page With Timings Of Its DB Calls

I am looking for a tool/product (commerical or shareware) to correlate
classic ASP pages (not ASP.NET) with timings of ADO calls made from
each ASP page. The information I am looking for are

T1, url = http://..../product.asp,
DB Server=SQLSvr1, DB Name=products
ADODB.Connection.Open 10ms
ADODB.Recordset.Open 189ms
...

T2, url = http://.../search.asp,
DB Server=SQLSvr2, DB Name=productindex
ADODB.Connection.Open 15ms
ADODB.Connection.Execute 350ms
...

It would be nice if the tool can automatically rewrite existing ASP
pages if necessary.

This would be a good performance monitoring tool for classic ASP
pages.

Cursor Count Problem In Recursive Calls

I'm using the following function, which uses a recursive call. every time when I get a conf it opens a record set. So increases the cusor count. Some times I'm getting the following error:

Many-to-Many :: Seperate Database Or One Database?

Products ---> Products|Customer <--Customer

With regardst the above many-to-many relationship:

Is there any advantage in creating seperate access databases for:

- Customer
- Products

....Rather than keeping them as three tables in one database.

The reason I ask is that I have found that if I am using a ftp approach to
overwriting or updating the remote database there are sometimes problems
with synchronizing data .....This seems to be a better solution?

Am I off base?

Job Database

They are on Windows 2000 IIS 5.0 and currently have an older version
of their job database using Access hosted on a Brinkster server.
The new server that they are on, when I contacted the host, they advised me
against creating any new applications using Access, as the server is not meant
for multi-users.
So, I am thinking that they need to get their host to upgrade to a SQL database
and have the job database developed using that.
My question to this forum is: What do you think is the best combination for
improvement here, SQL or MySQL or what, considering that their site is using asp
and hosted on Win2000 IIS 5.0?
Also, any recommendations on scripts that might be already available that could
be customised to their site?

SQL Database

This is probably a stupid question (I'm good at those)...
I would like to enable a user to be able to browse to a picture on their local machine and upload that picture to a remote directory where it can then be displayed along with it's other pertinent data.
I thought it might be a good idea to use Front Page's "file upload" feature which includes a "browse" button and prompts me for a storing location - but I can't get it to work and am not even sure if that's its intended purpose.
So my question is two-part, what should my insert or update page look like regarding an upload process, and then how would I link to or display that picture?
