Hi all,
I am programming a database that contains approximately 3700 records stored in a relational table structure.
When I split the database and moved the tables to the server side, my performance worsened drastically: a query that runs in under 5 seconds when the tables are on the client side takes over 45 seconds in the split database (with tables on the server side).
I've tried a variety of solutions (including changing the subdatasheet name property to [None] in the tables, creating an MDE file from the MDB file), but they haven't helped much.
Any suggestions about how to speed performance are greatly appreciated! Thanks so much!
I have split my database, the data is in a DB on the server and the forms, reports, etc is on the client desktop. My question is "Is there an advantage to having all of my combo box queries (Lookups) on the server side (defined in the table as a combo lookup) or should I put the all on the form so that they reside in client side DB.
I am new to Access programming. I read in some web page on googling that Access is for developing Desktop database. Books inform that Access projects can connect to Server database.
I would like to know if Access can also be use for Server side programming.
So I'm trying to manipulate Access to create a Directory for my church. I'm trying to get a report to show the church staff, which I was able to do, but I was wondering, is it possible to get the records to show side by side instead of one on top of the other?
I included a picture of the design view showing what I would like to see. Excuse the way the numbers are written, it's hard to write with a mouse.
Form with three sections. I have three queries selecting different set of set in a table, I would like to show all three in a form side by side. How can I do this? I use form wizard bit it only uses one query as a source.
I want to Delete only FK on the many side first and the record on the one side by one click of a button. I wrote some code which sometimes works and sometimes it does not!!
I wonder if any one have a better idea or doing this please?
Private Sub Delete_Click()
Dim db As DAO.Database, rs As DAO.Recordset Dim n As Integer, i As Integer Dim vStart As Integer Dim vEnd As Integer Dim vSite As Integer Dim vRCCID As Integer
vSite = Forms![frmSite].Form![SiteID] vRCCID = Forms![frmSite]![Roads Construction Consent].Form![RCCID] vStart = Me.PhaseStart - 1 vEnd = Me.PhaseEnd + 1
Set db = CurrentDb Set rs = db.OpenRecordset("tblPhase") rs.MoveLast n = rs.RecordCount rs.MoveFirst If n > 0 Then For i = 1 To n If rs![SiteID] = vSite Then If rs![PhaseNumber] > vStart And rs![PhaseNumber] < vEnd Then rs.Edit rs![RCCID] = Null rs.Update
End If End If rs.MoveNext Next i End If rs.Close db.Close Set db = Nothing Set rs = Nothing
'/////////////////////////////////////////////
DoCmd.RunSQL "DELETE RCCID FROM tblRCC WHERE RCCID = " & vRCCID & ""
'////////////////////////////////////////////// End Sub
tblRCC is the one side of the relationship and tblPhase is the many side.
I have a report with some text boxes on it. Sometimes the text in these boxes can be a very long string of characters (maybe a path to some folder). In this case I do not want the text box to grow. I just want the report to show me the right-hand side of this path and cut off the left. How do I do this when still aligning my text to the left?
I'm starting a year-long university project which will be written in c#. The client app will be run on a LAN, with 35-40 users accessing the database concurrently, connecting to a database held on the server.
Could anyone tell me if Access can withstand 35-40 users at the same time? I found out that the maximum amount of users is 255, but what kind of performance impact(if any) will there be with 35-40?
I've searched all over the Internet for this, but I can only find references to using access behind a website, which isnt quite what I need. Any help would be great.
Have a few questions after I ran the Access performance analyzer. Now these ideas are they good or just some generic recommendations. Dont know if I should take care of all these or not?
Anyone know if I should do all these things and about how I should do it?
Hello, I am attempting to convert some Access XP MDB files to Access 2007. I am experience some horrendous performance problems. We are a bit unusual in that we use Access as a RAD tool and almost all of our data resides in Oracle tables linked to by our Access front ends.
The issue I am experiencing concerns opening tables in the UI. If I open a table by double clicking it, a datasheet view is displayed (rather quickly) as usual, filling the page with information. The UI is responsive while Access populates its recordset in the background. (e.g. the the record count on the record navagtion bar is not displayed). As soon as I click in a column defined as a date, the UI hangs, network trafic and CPU usage rise dramatically and the Access Window displays "not responding". It appears that Access is attempting to retrieve all the rows in the table. After 3 minutes or so, the UI becomes responsive, CPU and Network traffic return to normal and the record count is now displayed (roughly 900K records).
This is "bad" (and also not what Office XP did). Please can anyone help?
I have an Access datebase, where main tables are built and saved.
Also, I have 2 Access modules, which access informations in main tables in an Access datebase (I used Linking to table) and process information in query.
Questions: Linking to tables in another datebases will make perfomance of the module worse ? If the answer is Yes, then in which scale ?
We are encountering severe performance problems when running our access database on our Network.
Symptom:
Huge drop off in performance when 2nd and subsequent users refresh links to chosen back end database. If the database is opened by another users front end database.
Takes up to 10 minutes to refresh the links to 120 tables in Back-end MDB database.
The system is designed as a split front and backend Access database. The back-end Data MDB database is located on a Windows 2000 server.
The first time a user logs on they are required to locate and Re- Link the tables from the back-end database which holds data for the current year. If they wish to work on another year they re-link the tables from the relevant back end database.
When running locally the Front end takes between 5 and 10 seconds to refresh ALL the links to around 130 tables.
When the back end is on a network drive the process takes about twice as long. But is still quick.
If another user has the file open via their own (locally held) front end, then the refresh link process takes between 5 and 10 seconds PER TABLE !!
This means that that it takes up to 10 minutes to complete the re-link. Same behaviour if using Linked table Manager or refresh links using code
As soon as second user logs out of database the refresh link process speeds up.
The behaviour has been observed on a variety of servers and customer networks.
General data access is also much slower after 2nd user - but just about bearable. Data files are small – few records – occupy 7mb on disk.
Development Platforms – Windows XP / 200 clients, Windows 2000 Server hosts the back end database.
Front end is Access XP (MDB or MDE File) with al the latest service packs and security updates installed.
We have experienced this problem with a number of different systems running in various environments. But this wasn’t a problem with the old Access 1 database
HELP! Access should be able to support 10 – 20 users - we can barely run 2!
I've been experiencing a very frustrating problem recently.
One of my databases crahes randomly, and I'd like to know if some of you have tips to helps me.
The database is splited in front-end and back-end, both on the server. I know keeping the front-end on the client PC will improve performance, but due to a high number of users (about 60 to 80) and the need of doing frequent updates, installing the front-end on each machines is not an option for now.
Users are not all directly connected to the server. Those who are directly connecte4d to the server (in building A) have no problem. Those who don't (building B) have extensive lags on opening (about 30 seconds), and on about anything that calls an heavy query, most often leeding to a crash. Access display the message telling that the datbase needs to be repaired and restart.
I tryed several thing to improve my queries, like eleminating most of GROUP BY and UNIQUE clauses and avoiding the use of functions.
I have a lot of conditional formatting in the forms, but I don't think this is the problem, since it is executed on the local machine (as far as I know).
My theory is that the lags cause some call to the DB to timeout. I just dont know how to fix that. Is there an option to higher the timeout delay?
My other theory is that the problem is caused by dropped packets during the connection to the DB. I tryed downloading large files (100Mb to 250Mb) from the server several times and never had a problem. Although the connection is quite slow, the ping is very small, like below 10ms to 20ms. Is there better ways to test a network connection, if possible without installing software (limited rights on the machine)?
Would using Replicas be a solution? What are the pros and cons of it? I never used them and know very little about it. My idea would be of putting a back-end on both servers, but I guess the data would not be as live.
BTW, I am using Access 2002 (2000 file format) on an XP SP2 PC.
Thanks to all of you patient enough to read all of this! I Hope some of you have some awnsers, tips or tricks!
I have an Access 2010 database .. and will be adding about 25,000 records a day to it. So it will get pretty big fast .. so 9 million a year. Is this too big for Access ?? Or is it more a issue of file size .. I know that Access 2010 can go up to 2 GB. I am interested in how I can maximize my performance and not have the database.The data is as follows .. One table. The other tables will be small, just this one will increase in size really.
Id .. Autonumber (primary key) When .. datetime Radio .. integer (indexed .. w duplicates) Group .. integer (indexed .. w duplicates) Type .. text 4 TransType .. text 2
I am considering a purge of old records if needed .. like only keeping the most previous 5 million records or some reasonable number. Like .. then I would think I should try to number my records backwards (using long int rather than autonumber and number records backwards on import) .. ie record 1 would be the most recent one and only keep the last X number of them for performance reasons.
We're currently looking at changing a couple of my more complex Access 2003 databases to Access Front End with a SQL Server Back End. This should give us better stability and reduce network traffic loads. I was looking at the Access help file on Upsizing and came across the following paragraph. On face value to a novice like me this would seem the easy option - but is it?
"Create an Access database front-end to an SQL Server database back-end so that you can create a front-end/back-end application.
This approach requires very little application modification since the code is still using the Jet database engine. "
I am importing an Excel file into a table in SQL Server that was created by an AS400 program.
I linked this table in MS Access. The date fields from the SQL Server table are split out. DSREQM is the month and day. DSREQY is the year. When opening the table it looks like this:
DSREQM DSREQY 215 6
I need to be able to convert this is a field to 2/15/06. However I cannot get this to work. For some reason when I execute the query it comes out as 8/02. Here is what I have:
I am attempting to write an application, using Access2003 as the front end. The Backend May be either Jet (ie an MDB), or SQL Server.
I am trying to make it so that the same code works regardless of the back end.
My approach has been to set the forms recordset to an ADO recordset like so:
Set Rs = New ADODB.Recordset 'Rs.CursorLocation = adUseClient Rs.CursorLocation = adUseServer Rs.Open strSQL, gcn, adOpenDynamic, adLockOptimistic ' Set Me.Recordset = Rs
Anyone done this, and willing to sahre information/pitfalls.
First problem I am encountering is that Jet only seems to like .CursorLocation = adUseClient, and SQL Server only seemns to like .CursorLocation = adUseServer
Hi to everyone Im not sure which thread i should be in, but here goes :confused: i want to create a members database for members on my forum with HTML!

I'm trying to help someone with Access on a CITRIS Server. I'm working with them VIA email. They say they're having problems communicating with printers and would like to utilize their email with Access. Can someone fill me in on common problems using Access with CITRIS Server as far as printers or email or anything else?
To be perfectly honest, I know nothing about CITRIS servers. Is CITRIS a hardware system or computer type of is it an operating system???
I need to be able to add a feature to an Access project that will select a group of records based on an area code( user will have to be able to select a desired number like 100, or 1000), mark those as selected, and create a single csv file...The area codes are stored in the SQL SERVER database...right now they just export groups of #'s based on area code to excel select the amount they want and cut and paste into a flat file for another application to use...they would like to be able to select a number from a list box or type it in...like 100 ( which means take a 100 #'s from all different area codes) then have them automatically noted in database as being selected..and then export all selections to one csv file... should I do part of the work in the Sql Server behind the scenes..the format of the csv file also needs to be specific in that the first row is the columns separated by commas and then the data follows all text fields enclosed by qoutes.. Thanks for anyone's help ..Im very inexperienced with VB and Access
I have created an adp, and have created stored procedures for all of my forms. In the SQL Server database I have given my users permissions as db_datareader and db_datawriter, however they were unable to open any of my forms because they didn’t have execute permissions on my stored procedures. I finally had to give them permissions as db_owner so they could use my forms. Do I have to give them db_owner permissions to execute my stored procedures? I know I can go in and assign them execute permissions for my stored procedures, but there has to be a better way. Does anyone know how to give users execute permissions on stored procedures without having to give them db_owner permissions or having to grant execute permissions for each stored procedure individually?
I am still in the development phase of my project and having to assign users or groups with each stored procedure I create could really be a pain. Can someone please help me?
I am accessing a SQL Server 2000 database from MS Access. While I can view the tables and can add records, I cannot edit or change them. How do I get around this?
I am trying to build a form to make deletes from our sql database easier for some of my coworkers.
They have a combo box that they select a patient name from, then based on that patient id, they have a second combo box that shows all appointments that patient has been to. All right so far, yes?
I want, after the first two selections are done and we have a patient and an appointment selected, to have a textbox that returns the count of the number of medical documents based on that appointment id.
I am trying to use a text box for this. Code: "select count(appt_id) from template_audit where appt_id = " & Me.cboAppointment
I don't know what property of a text box to use to return a single sql statement into it. Anyone have any ideas?
The database that I have on MS Access has tables, queries, forms (VB code), reports and functions (VB). I could migrate the tables and queries through the Enterprise Manager. I want to have the forms and reports in html. Is there any software tool that can help me with over all migration?
I've create an ms access security workgroup and put .mdb and .mdw file to a folder under any acount on a server. When these files in my local machine it work properly. But when these files on server I myself cannot open .mdb file. How to make ms access security on a server ?
I know and have worked with MS Access for over 3 years now. Just would like to know if there is very much difference between MS Access and SQL Server. Are they similiar or are they completely different . In terms of designing forms, reports, sql.
Appreciate some feed back and also where I could view or look at sql server.
