Hi,Simple question: A customer has an application using Access 2000frontend and SQL Server 2000 backend. Data connection is over ODBC.There are almost 250 concurrent users and is growing. Have theysqueezed everything out of Access? Should the move to a VB.Net frontendtaken place ages ago?CheersMike

I've created a small company database where the tables reside in a SQLServer database. I'm using Access 2000 forms for a front end.I've got a System DSN set-up to SQL Server and am using links withinAccess 2000 to get to the SQL Server tables.My forms worked fine until I made a few minor changes to the databaseschema on SQL Server (e.g. added a foreign key, or added a column).After that, all the links break - I click on a table link and get anerror msg like "invalid object name."Deleting the links after a schema change and re-adding the links seemedto fix the problem. The forms I'd already created seemed to work fineafter re-creating the links.But then I got more advanced with my forms. I have it set up so thatfor certain entry fields, the combobox gets populated with values froma table (the description appears in the drop-down and the correspondingprimary key value gets populated in the table). I created a number offorms using this technique, entered data, and everything worked fine.Made a small schema change and it broke everything -- not the actualtable links, but the functionality for the drop-downs. My values nolonger appeared, and this was true for forms that accessed tables whoseschemas did not change.This is driving me nuts. Is there any way to keep my forms frombreaking each time I make a small schema change?Thanks.- Dana
View 5 Replies View Relatedi went through the documentation but i was not clear on following, here is the scenario :-
a Central server is having SQL Server 2000
3 Remote Locations :- Each having 4-5 no of computers, connected on a Lan, and on one of the machines MSDE 2000 will be running.
My Questions are :-
1. Can remote locations, update data locally and send changes (say in every one hour) to central server. If yes, then how ??
2. Same way they can receive updates from Central Server on whatever was updated on Centra Server or on the 3 remote locations. If yes, then How ??
any help will be highly appreciable.
Hi,
I worked on a project in ASP.NET using SQL server 2000 as the back end. Its a conversion application that I rewrote in ASP.NET using C#. I need to import the old data in Access db into SQL server 2000 and I have very little knowledge about doing it. The data in not a direct one -one transformation. There are considerable changes to the Database design and data types. Any help and suggestions wud be really helpful. Also, any article links wud be great.
Thanks
We have a SQL Server 7.0 system in NT 4.0 environment. We upgraded our users to Access 2000 and started to work with this. Now we installed a new
server which is Windows 2000 based and the domain is different from
the SQL servers domain. We then installed Access 2000 on Windows 2000
to use with terminal server. But I noticed that there was a problem
with the program. I then looked at the program which was written on Access 2000 and saw that the tables and views can't be seen. The program runs but
I can't see the views and tables. Another thing is access disconects from SQL Server when I want to see the tables. So what can be the problem.
In one part there is an Access 2000 on Windows 2000 server. On the other part SQL Server 7.0 on Windows NT 4.0. And Access can't see the tables in SQL server.
We are experiencing a problem with Sql Server 2000 linking to anAccess 97 file. We have two machines that link to this .mdb file, andwe recently upgraded one to newer hardware, SP3a, MDAC 2.8, etc. Thelink on this upgraded machine no longer works, giving this message:Server: Msg 7399, Level 16, State 1, Line 1OLE DB provider 'Microsoft.Jet.OLEDB.4.0' reported an error.[OLE/DB provider returned message: Cannot open a database created witha previous version of your application.]OLE DB error trace [OLE/DB Provider 'Microsoft.Jet.OLEDB.4.0'IDBInitialize::Initialize returned 0x80004005: ].The link on the older machine still works. We decided to tryconverting a copy of the file to Access 2000 to see if the newerpatches/drivers/whatever no longer supported 97. We set up a link onboth machines to this file, and they both work. However, on theupgraded machine, the following error is receievedServer: Msg 7399, Level 16, State 1, Line 1OLE DB provider 'Microsoft.Jet.OLEDB.4.0' reported an error.[OLE/DB provider returned message: System resource exceeded.]OLE DB error trace [OLE/DB Provider 'Microsoft.Jet.OLEDB.4.0'ICommandText::Execute returned 0x80004005: ].when making 1-3 connections to the the linked server, while the oldermachine supports at least 7 simultaneous queries connecting to thelinked server and still hasn't produced that error.Does anyone have any idea if there is a known issue with linking toAccess 97/2000 files under MDAC 2.8, Jet 4.0, etc? Any light anyonecan shine on this subject would be greatly appreciated.
View 1 Replies View RelatedI am converting a MS Access 2000 project to use SQL Server. This project has uncovered a number of problems, my latest seems to be very odd.
When I query using ADO against the SQL Server database, the results don't seemed to be returned immediately. It's like the access methods being used are waiting too long to write/read the data.
This could be a simple ADO configuration error, but I cannot find any settings that would make this behave so strange.
I'm using OLE/DB drivers with trusted security and attaching using client-side recordsets (I tried server-side as well, same results) to get data for the Access form. In many instances, the data from the form is not yet retrieved when I check the results using the debugger. If I execute the same section of code just seconds later, it works without fail.
I ran the SQL Server Profiler just for grins and found that records were not getting written to the database as I would have expected. Apparently ADO had generated a transaction and rolled it back. (why I don't know) I have looked in Microsoft's support database and on MSDN to no avail. Rather then rewriting my T-SQL as stored procedures for these functions, I'm hoping for some insights from anyone else who has been down this nasty road.
Here is the exact scenario:
Problem #1:
A form that accepts data and has an update button does not update the recordset being used to populate the form. I even coded a rst.Update statement into the code. The record within the recordset isn't updated until the DoCmd.GotoRecord , , acNewRec call has been made.
I suppose I could code the insert statement myself, but shouldn't Access be updating the database for me. (it does have r/w access)
Problem #2:
A subform that performs a query and allows records to be added to a table does not correctly detect data returned from the query. A check is made in the code for a field (which has a value of 0) but the code detects a null value. If I step through this code in the debugger, enough time passes that the value is present and I never see the problem. If I set a breakpoint at the error, the null condition is indicated, even though the debugger shows a value of 0 for the field.
SQL Server version is 2000, with SP3a applied.
I updated the MDAC to 2.8, JET to 8.0 and still the same problem. I cannot find anything in my ADO or Access books for a setting that would cause this behavior. My connection is using the following info:
Set Conn = New ADODB.Connection
Conn.CursorLocation = adUseClient
Set rst = New ADODB.Recordset
Connection string: Provider=SQLOLEDB;Data Source=myserver;Initial Catalog=mydb;Trusted_Connection=Yes;Integrated Security=SSPI;
Recordset Cursor type: adOpenDynamic
Recordset LockType: adLockOptimistic
I open the recordset using:
rst.Open mytable, Conn, adOpenDynamic, adLockOptimistic, adCmdTableDirect
Problem # 1
After manipulating the data in the form, I press a "save" button on the form. This button calls a number of subroutines, eventually executing the code below:
rst.Update
DoCmd.DoMenuItem acFormBar, acRecordsMenu, acSaveRecord, , acMenuVer70
Problem # 2
I set the recordsource using: (in the form_open)
Me.RecordSource = "Select * from mytable where myfield = 'data'"
In the form_unload, the problems occur. It tests for a value stored in the form from the query. This value is null at the time of the code execution, it has a value when inspected within the debugger however.
Maybe I'm missing something here, this project was originally coded using DAO. My conversion to ADO is 95% complete. (all of these two components are converted to ADO) This problem is causing me to miss out on sleep and look like a rookie.
Has anyone seen or heard of something such as this? Is there any hope for this snarled mess of 25K lines of code?
Thanks!
Hi,I have developed an application using VB 6 (SP 5), MS Access 2000 andCrystal Reports 9. I migrated from from access to SQl Server 2000.This wasn't a problem as i could import all the tables to SQL Server.Also, i could make VB6 talk to SQl Server.The problem arsies when i run my application. The sql syntax foraccess seems to be different than that for SQL Server. A simpleexample being: In access boolean datatype is true/false ,whereas inSQL Server the boolean equivalent is bit (numerical 1 or 0). Thesekind of issues are causing problems and most queries don't run.Would i need to go and change all the queries in accordance with SQlServer syntax ,which would be very time consuming or is there anyfunction which will convert the access datatype into its equivalentSQl Server datatype??Any input/thoughts/suggestions would be appreciated.ThanksJatin

I need to replicate data from an Access (95-97) database to my SQL Server 7.0. There is a lot of different techniques availible, unfortanly none of them are easy and performance is also often bad. Suggestion for a way to do it will be appreciated. The following considerations exist.
* Data only to be transferred from access database to MS SQL Server
* Tables in Access database contains a large number of records (, that might change.
* Development of a program in VC60 or VB60 is OK
Any inputs appreciated.

Does anyone know the correct procedure to setup a pull relationship from MS Access to a SQL database and vice versa?

Is this possible?

Hello @all,
does anyone know whether a SQL Server 2005 Everywhere database can be replicated with a common MS Access database? Is there any possibility to synch a database on a mobile device (SQL Everywhere) with a central database on a server computer (like MS Access or SQL Express) without having to use a full version of SQL Server? Replication is just needed for merging a small database (4-5 tables) so I think the full version of SQL Server is a little bit oversized for this issue (and too expensive, too).
Thank you very much in advance,
Tim

Hi,
I am in between of analysis for Upgradation of SQL server 7.0 to SQL server 2000.
I have few server on SQl server 7.0
I wanted to know , is the replication supported between SQL server 7.0 and SQL server 2000.
a ) from SQl server 2000 to SQL server 7.0
and
b ) from SQL server 7.0 to SQL server 2000.
Both this scenarios will exist.
Thanks in advance

Hello,
I am using MSDE 2000 for replication of my Data. I have one publisher and two subscribers. but i need t filter rows for publications. Problem is that for filtering, i need host_name and in push replication host_name is name of system in which Agents are running but in MSDE all agents are running in publisher system ( distributor System). so everytime for any publication i get only id of server.
i am facing same problem in pull replication also.

Any suggestions on how to replicate from AS/400 to SQL Server 2000?
Data is stored on a AS/400, but applications use a SQL Server 2000 DB. Currently, DTS packages drop the SQL DB, rebuild the tables from a script, copy the data, and then rebuild the indexes as a nightly batch job. Is there a better way to do this? Also is there a clean way to replicate daily transactions as well?
Hi
I'm trying to determine if it is possible to do many to many replication in sql server 2000.
What i basically want is to have n databases share the same basedate (share a common database) and allow updates in any database to be replicated to all the other databases (with a simple conflict resolution, like last update wins).
My goal is total autonomy, without a single point of failure. If any node goes down, the other nodes will continue to work and continue to replicate their data to the remaining nodes. When a node comes back up it will catch up with the over nodes (or get reinitialized if it was a serious crash).
The amount of data i want to replicate is not that big (less than 100MB) and does not change that often. All servers are sql server 2000 instances connected by a gigabit network and the number of nodes involved is less than 10. Some latency is also acceptable.
the question is: is this at all possible? I have read i bit in 'SQL Server High Availability By Paul Bertucci' and some other resources and it looks like a multiple publishers or multiple subscribers with merge replication setup should work, but i'm not too sure if it will work for n > 2 nodes (where all nodes publish and subscribe to each other) and it also mentions constraints on which data a given node is allowed to update (i hope this could be handled by simple conflict resolution).
And if it is not possible in 2000, could it be accomplished en 2005?
TIA Jens
Hi,
Can anyone help me?
How do I implement SQL Server Replication?
Where, and how? Do I have to download specific software to do this, or how?
What would be the right option?

Morning Guys,
If one was preparing to Replicate a database and need to know how much more size would be needed to accomadate the distribution database and its transaction logs etc... what performance counters would you set to gather this information and or tools...?
How to go about finding the average tranaction size.... number of transactions per day.... via profiler.... perfmon....
any suggestions or good sites for replication would be greatly appreciated...
thanks,
thanks,

Hello
I am facing a very severe problem in SQL Server 2000 replication and here's the description :
I had setup a replication having Publisher and distribution on the same server. Later I found out that the Subscriber database was incorrect and so I dropped the replication and then disabled it so as to start from fresh.
Now as soon as I start to configure the Publisher/Distributor I get the following error message :
"Error 18483 Could not Connect to ABC Server because distributor_admin is not defined as a remote login at the Server "
Please let me know what can be done to resolve this issue
Please help me to resolve this issue as we need to have the replication latest by Sunday 4/21/2002
Thanks again
Hi all,
I'm trying to configure replication between a Sybase ASE Database Server and SQL Server 2000. Sybase ASE Database will be the Publisher and SQL Server will be the Subscriber. Can anyone advise me on how I can go about setting up the replication for this?

Hi,
I have set up transactional replication on two servers. The productionserver (PSERV) and a backup server (BSERV).
On PSERV I have started the agents Snapshot (running with status Succeeded) and Log Reader.(running with status Idle and the message "No replicated transactions are available").
On BSERV I choose start syncronization on my subscription. When I go into Job history I can find the following information on four lines:
The job failed. The Job was invoked by User SERVAdministrator. The last step to run was step 1 (Run agent.).
The subscription to publication '(null)' has expired and does not exist. The step failed.
Connecting to Distributor 'SERVP'
Connecting to Subscriber 'SERVB'
Anyone that have any ideas on how I can fix this problem?

I am using SQL Server 2000 SP4 running on a MS Server 2003 with SP2. I am preforming Merge Replication on a continouas basis and the Merge Agent keeps stopping with the error 203 The process could not enumerate changes at the 'Publisher'. There is no additional information available with this error. Does anyone have any sugestions as to why this is happening. I can manually re-start the agent but it will fail again for particular reason.

we are trying to replicate an sql server 2000 database to another sql server 2000 database.
We are having problems because at some point we deleted the column showacc from one of the tables. When we try and replicate the database we get a complaint about an invalid column showacc.
I have tried doing a select into a blank table and setting the defaults and renaming the table, but even that didn't work.
Any ideas what I can do on SQL server 2000 to get replication working properly?

Hi,
We have few branches with individual dbs are sitting in the branches itself. Periodically all the data need to be updated to a single HQ database. At the moment, all the tables's primary key are unique and each branch will have branch ID's in the transaction tables.
e.g. Branch1 data need to be updated to HQ db. However, HQ db records which are related to Branch 1 data only need to be updated back to Branch 1. other branch records should not goto Branch1.
Similaryly other branch records need to be updated/replicated back to HQ database. And only records related to the particular branch need to be updated from HQ (if any changes made)..
At the moment, i can do simple replication from one db to another db only... Can anyone guide/give suggestions on how to go about doing this?? If possible, please give steps involved...

Hi ..
I know that SQL Server Express 2005 can subscribet to SQL Server 2000 publications. However, it seems that SQL server 2000 cannot perform a push to SQL Express.
Can anyone refer me to any online help or documentation on how a proper replication can be done between SQL 2005 Exress and SQL 2000??
Thanks
I want to replicate SQL Server 2000 data from publisher to subscriber with new data added and existing data modify at subscriber, is it possible? what is the solution.
Any idea as to how SQL Server ensures that no data is lost during replication. In my project we have some across several instances where the SQL server indicates that the data has been replicated but it is not recieved at the other end. The network is not very reliable, in case the network link is lost during replication how does SQL ensure no data is lost. If you know the answers or have any documents please share the same.
Thanks,

Hi all SQL Server experts!
I have created replication on my two servers (production and backup servers). I used wizards to create it and then generated SQL script for deleting and creating replication. For another task I came across the command sp_removedbreplication 'dbname' and I tried to use that for removing replication more easily on the servers. It seemed to not remove everything on the production server and whenever I install replication now, either by using wizards or my generated SQL scripts I get an error icon (red circle with a black X in it) on my Replication Monitor all the way down to Publisher and the publication named with the computer name. Also this icon is on Agents and Log Reader Agents but not on the actual agent.
Something must have happened when using sp_removedbreplication 'dbname' and I can't fix it. The replication works properly but i wish to not have the error icons.
Does anyone know how the error icons can be removed?
Best,

Hi, I posted about this before, and set out on my own to get this working, and haven't been able to. I'm trying to get merge replication working with my SQL server 2000, and after 2 weeks I still have nothing. I've gone through multiple 'walkthroughs' which all brought me to the same point. I'm getting down to crunch time, and I'm either going to use this or implement my own merge algorigthm (I'd much rather use this). So here's where I've gotten to:
