Help Understand Logic Of Moving From Access To SQL
Apr 14, 2006
Hi all,
Please, I need some help understanding what I need to do.
I'm working with text files and they're too much for Access to handle.
The logical conclusion is to use something more robust like SQL.
I'm having trouble understanding how it would all fit together, and I'm looking for guidance.
First of all, what do you think is a logical approach to this problem: I get 6 .txt files delivered to our webserver via ftp. Every night there's an update, so they overwrite. I need to be able to display that data on the web page and I thought I could use Access to do it. Well, it won't work, so then there's SQL.
In my reading today, I find out that SQL isn't an environment like Access, it's a language. I'm assuming that means I can't just import all of this data into an SQL db, get it on the webserver, and then start running queries against it like I can in Access, right?
If one of you more experienced users has any ideas, please share. How can I use SQL to search the data in these .txt files? Included with each text file is a .dic file containing field names, data types, and length. What is the best approach. Step by step would be wonderful as I am very new to this. I have only ever worked with SQL queries and Access db.
Thank you for any help you can offer.

I am using C# and ASP.NET 2.0, with SQL Server 2000. In my database I have a table that is similar to the following:
WebpageId WebpageAddress Handler 1 /company/about ~/about.aspx 2 /blog ~/blog.aspx
As you can guess, one of my queries will be a SELECT command where WebpageAddress = @address.
The hiccup I have is with a friendly URL such as the following:
/blog/2005/10/6
The friendly URLs have no extension, so I cannot immediately "pick out" the extension. (If the address were /blog.aspx/2005/10/6, then things would be simpler.)
What I am doing at present is using a loop in C# where I first perform a query with that full address. If no match is found, I trim the address back to the last slash (/blog/2005/10) and perform another query. If no match is found, I trim the address (/blog/2005) and perform another query. Again, no match is found, so I trim the address again (/blog) and perform yet another query. This time, a match is found, in which case the URL rewriting looks vaguely like this:
~/blog.aspx?parameters=2005/10/6
While this works fine, these friendly URLs require hitting the database up to four or five times. My question is, can this looping logic be moved to SQL Server?
My SQL knowledge is extremely basic, so I am just looking for someone to point me in the right direction. If it is not possible, I'd love to know now rather than wasting hours trying. If it is possible, I've love to know the keyword or technique involved, so that I can Google for the full answer.

I have been using MS Access for a long time. The last couple of months my sites have really picked up in business (good rankings) and we keep crashing the server (No sites on the server that use MS Access will run) We get the errorSystem.Data.OleDb.OleDbException: Unspecified error at System.Data.OleDb.OleDbConnection.ProcessResults(Int32 hr) at System.Data.OleDb.OleDbConnection.InitializeProvider()at System.Data.OleDb.OleDbConnection.Open()at DreamweaverCtrls.DataSet.DoInit()Also I am finding out from some of my customers that their sites they can't use at times because of the error but the server hasn't crashed yet because others are up. Well I believe we are exceeding MS Access very badly because it crashes the server daily now and sometimes more then once a day. So I am going to start moving my MS Access database to SQL but have NO CLUE how where to start etc or use SQL correctly. If people can point me in the right direction that would be very helpful. Everything I find online is people needing help but no solutions that work for me. My new server is a windows server running ASP.Net 2.0 and to edit my SQL I have "ASP.Net Enterprise Manager" and Plesk for the server.1. A good book to follow and easy to follow for SQL (connections / how tos) or website2. Good examples or book on "ASP.Net Enterprise Manager"3. How to convert access databases into SQL easy (some have over 50,000 listings)4. how to convert Tab files into SQL easy.Thank you so much for any help. Also I am using Dreamweaver for most of the edditing and connections. I know its not your favorite but I don't have the time to write everything by hand and it works good for what I do on the websites.Thanks again,Rusty

Our Branch uses an Access Database, but we're thinking of rolling it out to our entire organization. I've just spent the day watching about 7 tutorials on SQL 2005, but they only use Management Studio Express in the tutorials, and before I go any further, I'd like to make sure I'm going down the right road.
Am I better using the Upsizing Wizard in Access to convert our DB to SQL? Once I've done that, what's the best way to get the rest of the DB on the Web so that our entire organization nationwide can use it? Do I need to learn Visual Studio or something so that I can recreate all our Forms & Reports? Do I even need to do that? Is there a conversion process?
Sorry for being so vague, but I would just like to know what is the best way forward. What do most people do when they want to move an Access DB to SQL and make it available outside of their LAN?
Thanks in advance for any advice anyoe can provide.

Hey guys,
I was just trying to get some information on how to move an Access 2002 db to MS SQL. Also, what all do I need to be able to access the db from the web. For instance, query the db for info from a website. I don't have that much experience in SQL but I quiet a few programming languages so i'm sure i'll learn it quick, I usually do. Right now I have a server set up with MS SQL server 2005 with all the other things required for testing over in my own little world. DNS, Active Dir., etc....
I'm trying to do this because a friend of a friend has a business(small businessish) who wants to be able to view reports from queries over the internet. And i'm sure I can do it but i told them to let me give it a test run to make sure I can before we commit.
Thanks in advance.

Hi there everyone, I have written a database system which tracks the performance of working in a shipping company in access. Im now rewriting the system in sqlserver and the only real problem I have found so far is that its difficult to estimate what kind of a server *cpu* & *ram* would be appropraite. The system currently performs transaction on my desktop machine in a second a quickest and 2 at slowest.
There are going to be about 500 users in 3 time zones so there will only really be about 300 max hitting the system in an hour.
I was looking at a Dell Poweredge server with twin P3's and half a Gb or ram would this be a good place to start from?
Any Advice would be great!!!

Hi all.
I am not a programer but managed to piece together an Access database that is the backbone of my company.
My IT group advised me to move to an SQL server back end and move to a web based front end.
My question. I am very comfortible with Access and modify the databases regularly. What front end is most like Access for modifying forms, reports, macros, etc.
Thanks!

My company is currently using access to manage equipment in 4-5 different locations. I want to move this to a sql database and have a front-end to do the same thing access is doing now.
Should I use access as a front-end or should I develop a custom front end using vb?
Just a fyi
5-7 tables
7-9 queries
10 or so reports and the front end is currently a switchboard that links to many other forms.
I'm looking for advice.
TIA

Hi All,
I'm new to SQL server. Basically, I am trying to make my Access database accessible on line to my users, so I am transfering it into SQL Server and then writing a web site to use the connection to the database.
My questions are as follows:
1) How can I easily move the structure of the tables (relationships too, but content is not important) from Access into SQL?
2) I have the following query in Access which I don't believe will work in SQL because of the Sum funtion... How can I change this to work in SQL?:
SELECT DISTINCTROW Player.TeamID, Player.PlayerID, Player.SFD, Sum(Payments.Amount) AS Payment, [SFD]-[Payment] AS Due
FROM Player INNER JOIN Payments ON Player.PlayerID = Payments.PlayerID
GROUP BY Player.TeamID, Player.PlayerID, Player.SFD;
All help will be greatfully received... thanks

I am having a problem reinstall SQL Express 2005. I had it installed, but then I unistalled it. I have tried installing it again, but everytime I do it says that the product is already installed. There is no instance of it in my Add/Remove Programs. I have read the threads that relate to this topic, but they haven't helped. I have looked at my logs of the installs, but they don't make sense neither. I just want the program installed again, or a way to get it so that I can use it.
When I try to manually uninstall using msiexec.exe /x <processid> I get an error saying that the package could not be opened. This happens with all the process ids I use that I get from the log files (I have 11 logs).
am using Visual Basic 2005 and trying to create a database, and it will not let me. That is how I know that it is not installed, plus I can't find any instance of it one my computer. Please help. Thanks.

Then I tried to get the following result:
id GUID Version

1 abc 2
3 def 1
By using a query:
SELECT GUID, MAX(Version) AS MaxVersion, id
FROM dbo.Test_GUID
GROUP BY GUID
But then I get an error because id is not being aggregated.
This works
SELECT GUID, MAX(Version) AS MaxVersion
FROM dbo.Test_GUID
GROUP BY GUID
but then how do I get the id of each record?

The line this is happening on is:

I don't understand, it is giving that error particularly when I want to get ClientRepID
Some more lines from the code:
Response.Write("<TD><p>" + rdData("Username") + "</p></TD>")
Response.Write("<TD><p>" + rdData("ClientRepID") + "</p></td>")
The first line the compiler had no problem but when it gets to the second line with ClientRepID it gives me this error. (ClientRepID exists in the database)

Hello, i just bought sql server 2005 with 5 cals (previously i was using a shared sql server with my previous host)... I probably should have asked this question before i bought it... i don't understand how the cal licencing works... the sql server is for running our ecommerce site, i just got a dedicated server to put this on... but from reading the licencing does this mean that only 5 internet users can access my website(or the information in the database) at a time???
any help with this would be appreciated

The thing is, I do not conceptually understand what is happening and it is driving me nuts. I have read and re-read the description of quoted_identifier in books online and I still don't get it. How does the extra ' after joe make it work? Is there any hope for me? :)

Hi,Newbie here. I have a mailing list program that I really like. I also have anew membership program. The membership program has mailing list signupsbuilt-in, but it isn't nearly as robust as the stand-alone mail program.If someone signs up for a newsletter when they register (membershipprogram), can a "trigger" in SQL Server put the same information into thestand-alone program's tables? And when they remove or update theirlists/info? And vice-versa?Is this what a "trigger" would do? And is it efficient?Thanks,JA
