Front End Development Language Choices
Feb 18, 2003
Wondering if anyone has pro's and cons for choosing a vehicle to build front end applications for a SQL Server 2000 back end.
Historically we used Access 97 with VBA code to create client side ODBC connections. In Code we would issue stored procedures through a connection string. This worked fine.
With Microsoft moving onward our company is transitioning to supported products. So DAO is dead.
My colleagues like Access 2000 and have imported some 97 databases doing small re-writes to make them work.
Everything I read says we should be interacting with SQL using ADO.
The other problem is not all users have admin rights on their machines, so adding application extensions for VB6 is a problem. We might be able to change this.
Should we just build with Access 2000 from scratch using ADO to avoid JET?
Should we use VB6?
Is there another application we should be looking at?

I'm getting ready to start a fairly large application to be hosted onSQL-Server. In the past I have used Access 2002 (as a front end, wasn'thappy with the number of bugs I ran into), PowerBuilder 6.5, Oracle Forms 7years ago (also no happy with the number of bugs). I was curious what thestate of the art was these days and what current recommendations were for4GL type of development tools.Thanks,Doug Broadwell

I'm trying to build a sproc with a where cluse that looks at a boolean field. I need to say if [Primary] is 1 then show all primary phones. If [Primary] is 0 or Null then return all records. I have it started like this;
WHERE dbo.tblPhones.[Primary]=Isnull(@PrimOrNot,dbo.tblPhones.[Primary]=1) Or dbo.tblPhones.[Primary]=0
Thanks for any help,

"TempDB in RAM. This option allows SQL Server to process the results of intermediate database operation in memory rather than on the hard disk. If you have enough memory available, using TempDB in RAM can dramatically improve performance of sorting, GROUP BY calculations, joins and queries that require temporary work tables"
Hi, that was a quote from MS white paper over the internet... Does that mean that I can get faster query output once I used the temp DB in Ram... what other things which I do not know that I may worry about if I use tempDB in Ram...
when allocating some ram to the tempdb, does that mean that I am not going to use it ... Please advice

I am developing an application that uses SQL Server 2000 for the back end. I am at the stage where some modules in the app can be tested while I finish development on some others. I run my own tests against SQL Server running on my own PC but for other people to test I have set up another server with SQL Server 2000 and have restored my database there.
My question is as follows:
I would like any changes to my database (structure and data) to be replicated on the test server's database (not necessarily immediately, but without much delay). I've heard the buzz words (log shipping, replication, etc) but would like some advice on the best way to proceed.
At the moment I don't need any data back from the test server and I don't particularly care if test data on that server is lost although these may become issues later on.

I need to pass a parameter to a stored procedure that allows the user to select all store numbers or a combination thereof.
The portion that selects all works fine. I am have trouble with the later. My code looks like this:
CREATE PROCEDURE vch_GetSurgeryPatientsWithoutOrdersFromEyeSite_clb
(
@StartDate datetime,
@EndDate datetime,
@center varchar (1000)
)
AS
IF @StartDate IS NULL
BEGIN
Set @StartDate = GetDate()
Set @EndDate = (GetDate ()+90)
END
Declare @StoreList TABLE ( CenterID int )
-- Get our Centers
IF ( @Center = 'ALL' ) or ( @Center IS NULL )
BEGIN
INSERT @StoreList
SELECT DISTINCT POS_Site_ID FROM LVIGP.dbo.POS40108 (nolock)
END
ELSE
BEGIN
INSERT @StoreList
SELECT DISTINCT POS_Site_ID
FROM LVIGP.dbo.POS40108 (nolock) WHERE POS_Site_ID = @Center
END
the first if statement returns all of the store number like this
CenterID
001
002
010
024
057
the second if returns nothing
I tried using coalesce but it returns the store number like this:
CenterID
001, 002, 010, 024, 057
This does not work with the rest of my program.

Hello,
I am searching for a resolution. I did a few searches on this site and could not gain the exact answer. I apologize is this thread is a duplicate.
I have written a report containing Multi-Values for Reporting Services. When a user selects the values for the report parameters, the checked values continue to be selected after the report is completed.
Is there a way to clear these parameters?
Some of our users run the same report more than once during a single web session.
Thank you for your attention!

I need to make a brief presentation to upper management about High Availability options in SQL Server 2005.
Current choices being considered are:
- Failover clustering
- Log shipping
- Mirroring
Q1: Are there other choices?
Q2: How do these choices compare in terms of cost, complexity of setup, ease of deployment, recovery procedures in case of a disaster?

I'm building a hosted website and I am using SQL 2005.
The DBA for the host has told me that i can not encrypt a symmetric key with a certificate, when using that symmetric key for encryption. As i read that this method provided optimum performance/ security for encrypting columns of data.
The DBA told me i can use a cert or a symmetric key for encryption.
I have searched for comparisons and found a blog entry by Laurentiu Cristofor comparing certs with asymmetric keys. Which leads me to believe that certs and asymm are very different than symmetric keys.
My question is which is the best choice in a hosted environment for column encryption, a cert or symmetric key.
Which is more secure? Does one offer a significant performance (dis)advantage?
TIA

Has anyone encounted a problem with Reporting Services (2005) with the following scenario:
A report with a dropdown parameter allowing a Select All choice -
If the selection list is fairly long and Select All is selected - if the user clicks the View Report button the selection list is completely reset (i.e. all items are unselected). This seems to happen if the user quickly clicks the View Report button immediately after clicking the Select All box on the parameter dropdown.
This happens inconsistently - some users experience it frequently while others do not see it at all (using the same parameter values, etc.)

Sorry for the lengthy question, but here goes:
I currently have an access database with a FE and BE that resides on each users laptop. Weekly they connect to the network and synch the BE the master on a network drive. There are numerous propblems with this as it has grown quite extensive.
We would like to have this be a server based database with the remote users either having access through the web or something else?
A few of the capabilities of the current database:
1. generate and print reports 2. update project forms. 3. enter time logs 4. enter notes
My question is:
What are my options for a remote FE? I am well versed in VB6 and Access. Would be willing to learn other languages (VB.net, my SQL, etc.) Would I be able to have the same functionality or would I have to have separate software for certain functions?

Hi,
If I don't have any visual studio design tools etc.
Is there any way I can build a simple form that will allow users to view, insert, update and delete single rows from a SQL 2005 database?
Or is there any free downloads that might help. the table is really simple and has only 4 fields

I'm doing a database for employee info and thier payroll.. im using SQL Serevr 2000 and IIS but i'm not too sure what to use as the frontend, a VB would kinda be overkill because each employee just needs to be able to update his own info and addresses, maybe a XML or some other page that uses windows logins for authentication? any ideas, this is my first project like this on on a college Coop

i am almost finished building the front end for an application to manage restaurants. i am developing the front end with access vba, and intend to use sql server as a back end for the service. i just came across a group of people bashing access developers on a different site. i have several restaurants interested in using the service, and believe that the service should be very successfull (i have a very specific customer base that is currently not being targeted). the access component would not be a multiuser application. before i distribute the app i would appreciate any input. am i getting myself into trouble using access vba? should i run scared and switch to a vb.net web service?
thanks in advance for any thoughts.

Below is a post by blindman from my other "mentoring" thread (http://www.dbforums.com/showthread.php?t=1608569). I wanted to respond to it but not in that thread:
Yeah, but if he's going to go unbound he might as well develop in .Net rather than Access. You lose half the convenience of MSAccess as a front end if you use unbound forms and controls.
Besides, he's trying to learn SQL Server, not front-end development. Learning both at the same time may be a bit much. I'd suggest he stick with his idea of converting the Access database to SQL Server back-end.
But, you should definitely convert the Access front-end to a Microsoft Access Data Project, rather than a classic mdb file.
Going unbound would increase your application performance, but probably not noticably unless you have scores of uses, and since you are currently using straight MS Access I'd guess you have no more than five or six simultaneous users, right?
blindman
To start I have decided that ADO is the way to go even though I don't necessarily need the performance boost for my current situation. Keep in mind I am planning for future and more demanding opportunities, hopefully :) And I'd like to learn the "right" way to do things.
I actually use ADO quite a bit in my current DB app and bound controls as well so it really wasn't a new concept. However using strictly ADO produces alot more work and code. And like blindman says it pretty much takes all the ease of Access away and VB.NET for that matter too. I mean all the wizards are useless. So I have two questions:
1. When going to all ADO you are pretty much recreating what Access already does for you right? Coding in ADO is more work right? I mean you have to setup connections and fill fields and listboxes manually in code right? I don't mind the extra work I just want to make sure if I'm going to be doing all this extra coding that it is the right thing to be doing.
2. MDB vs. ADP - From what little I've read Access Data Projects are made for use with SQL Server. It is even more useful if you don't/can't actually work in SQL Server. But again if I'm using ADO it strips all the usefulness of the ADP's doesn't? I don't need ADP's to create views or sprocs. I can do all of that through the management studio. So does it really matter if I use an ADP or MDB as my front end if that is all it is going to be is a front end?
Lastly I wanted to use VB 2005 as the front end but we utilize a ton of reports. As far as I know Crystal Reports or something like it has to be used with VB 2005. Or does VB 2005 have some built in reporting capabilities? I thought I saw some report designer for VB6. Anyway I decided to stick with Access because I am familiar with its reporting capabilities.
I should note that I have VB 2005 Express and SQL Server Express. Right now my company is not putting any money into a higher version.
Let me know what you all think.
Thanks,
GG

Hi!I'm trying to build an app. for my parents' office. They have a smalloffice (5 PCs), and they currently work with a very old program that'sbased on DOS. The program doesn't work well under XP, so they still useWin 98. They had their network upgraded about a year ago. They hadMicrosoft SBS 2000 installed, it includes SQL Server. I've written afew DB's in Access before, and now I'm just learning how to use SQL.Before I start work on their app., I have a question:I know it's possible to create an interface that can be put on theirnetwork and accessed via a browser. How is this done exactly?It would be very beneficial for me, because it would mean that the newapp. would be platform independent, so that they can upgrade to XPeasily. It would also save us the cost of licensing front-end software(e.g. Access) for each machine.Any comments would be appreciated.Noam Nelke, Israel.

Hi
I have a scenario while creating a report where I need to maintain the same number of rows for a column, even if the data grows or shrinks for that column
example
Each Scenario is grouped by ID
Scenario 1
columnA
Row1 X X
Row2 X
Row3 X
Row4 XYZ
Scenario 2
columnA
Row1 XA
Row2 XYZ
In both scenario's I need to control from front end
the number of row should remain 4
I am grouping by row field say Type
This field Type varies for each ID group

Hello all. Yes, this is another question relating to how to make a front-end to a SQL database using ASP.NET. I performed a search in this forum and did not find the exact answer to my questions (one responder to the other threads about this topic even said this is the incorrect sub-forum for this question, but I found no other appropriate place; considering this sub-forum is for asking beginner questions).
Besides the "quickstart" tutorials linked off this site, can you point me to other web resources (tutorials, walk-throughs, etc) or books that would provide the necessary information to develop a SQL front-end? Specifically I need help creating the Update Record and Delete Record pages.
I was hoping a "rapid development" tool could be used. At my disposal I have Visual Studio .NET 2003, Dreamweaver MX 2004, and FrontPage 2003.
Thank you for your time.

I am using Access 97 as a front end to access SQL 7 server on NT 4.0 server.
I've set up security model based on NT authentication only. Users have login right to login to SQL and they have public & dataread & denydatawrite access. They also have SELECT permission on a table object and have no permission to INSERT, DELETE and UPDATE.
When I use Access 97 to access a database, users are still capable of inserting and deleteing records in tables.
Am I doing something wrong?
Thanks, Michael.

Maybe because I have worked mainly with VB as a front end to SQL Server so I am biased, but I now need definite reasons (I am on a committee for potential future directions) for using VB as opposed to Access for front ending SQL/Oracle, etc. I would also like to use ADO as oppose to DAO. Right now we are using Access with DAO.
Any ideas greatly appreciated.

Hi All,
From front end application, I execute a SQL
`exec sp_password oldpassword,newpassword
and I got error message :
"Error code# 15002 :[Visigenics] [ODBC MS
SQL Server 6 Driver] [MS SQL Server]
The procedure `sp_password` cannot be
executed from within a transaction.".
If I logged in directly to SQL 6.5 without going
thru the front-end application then I could
change password successfully.
Has anyone tried to change password FROM
a front-end application? Our shop uses
Omnis 7.3.6 as front end and SQL 6.5 as back
end. TIA.

Hi,
We have just moved a largish Access database (180mb, 78 tables, largest
tables have about 250k records) to SQL 2k. The original app had an Access
back end (now loaded to SQL), and an Access front end (on each client) which is using some
local temporary tables, about 600 queries, and several thousand lines of
code using ADO and DAO). The Front end was relinked to SQL back end. When
testing everything seemed to run OK, but under load (15-20 users) the new
app just crawls. Routines that used to take seconds now take 10s of minutes.
ODBC timeouts or blocks are common.
Any idea why should the SQL back end be so much slower than Access. both the
Access back end and SQL2k are on the same server (Win 2k Adv. with RAID 5,
dual 600mhz Pent III, 512Mb RAM).
I realize that Access is not the best front end but that is what we have to work with.
Any help would be appreciated, as I am ready to swith back to Access.
Thanks,
Jakub

My company uses MS SQL Server for the back end and a Retail specific CRM as the front end. I wish to develop some internal peices of software for our use. I was planning on doing this with access.
my options are:
*Use access as front end and backend
*Use access as front end and SQL server as backend (create new DB)
*Use other front end and SQL Server as backend.
My question is, what are some good front ends that are availble for reletively small demands? How does Visual Studio come into play?
*Also, I would prefer to be able to create a .exe. I dont think access alows that. I would not want users to be able to go in (or even see) the tables and queries. They should only be able to see the one main menu form at the very least.
thankyou,
Dynasty
