General :: Maximum Access Users
Dec 9, 2013
I know that Access probably permits around 20 or so users to simultaneously access the database before it start to become unfriendly. However, I have a database that would require 200 or so users grabbing around 1,000 rows of data via an Excel ADO connection to the backend tables.
So they would never need to physically go inside the Access database its self, but instead it would garb data by opening an ADO connection to the database > Grabbing the data > Closing the database connection.
Is this okay to do with around 200 users simultaneously querying the database tables via an Excel ADO connection?

How many users can an access database support? I'm setting up an app accross 3 workstations but each has multiple users. There may be as many as 1000 records a day entered. Can an access database handle this or do I need to switch to sql server?

I am about to allow users to access a database I redesigned for others to use.I am trying to save it as an ACCDE so they can't mess it up. The database is very very simple.6 tables each with only 4 fields or less... and none are related to one another
7 forms.
1 report.
0 queries... it's just a SKU generator.
When I attempt to save as ACCDE I get an error that reads."Microsoft Access was unable to create the .accde, .mde, or .ade file.This error is usually associated with compiling a large database into an MDE file.* Because of the method used to compile the database, a considerable number of TableID references are created for each table.* The Access database engine can only create a maximum of 2048 open TableIDs at one time.* Exporting a database as an MDE potentially can exceed this limit if the database has a large number of objects (table, macro, form, report, etc).
There is no accurate method to estimate the number of TableIDs the Access database engine uses during the process of compiling a database as an MDE.* However, each VBA module and each form uses one TableID, as a result, if the database has 500 forms, and each form's HasModule property is set to Yes, as many as 1,000 TableIDs are used."

We have an access database stored in a shared location. One of the tables in the database is used to record transactions made in an excel spreadsheet-this is done programatically using VBA and SQL.
So here is my silly question; If users don't have access installed locally will the code be able to write to the shared access database?

I am using Access 2007. My boss has given me a project to create a tool for our team. I'm done with most part of the project, but for the last part I want editing and updating of database restricted to a few members of our team. However others can access the database and run queries etc. through buttons on a form.
I went about creating a login form for users to get access to the database and in turn created a table with fields UserID, UserName, UserPW and a yes/no field titled IsAdmin. For those who would be limited access would log in as 'Other' user and same as password. I am then using the code to determine if the user should be treated as admin or not by looking up the IsAdmin field in the table. Following is what I have so far, but it needs correction some places and I can't figure where:
Private Sub cmdLogin_Click()
Dim xxAdmin As String
'Check to see if data is entered into the UserName combo box
If IsNull(Me.cboUser) Or Me.cboUser = "" Then
MsgBox "You must enter a User Name.", vbOKOnly, "Required Data"
[Code] ....

My database is slowly coming together. For the final part of this phase i would like to create a shortcut on each users desktop which runs a summary report of information within my database.
I have criteria set so upon opening the report the user is asked for which address they wish to see information from which works great. But I do not want users to have access to the database, I just want them to be able to click a shortcut, be asked what address they are looking for and for the report to ping up in a 'Print Preview' type layout so information can be seen and displayed but not altered. All users have the access program.

As an "admin" of our corporate local db, maintaining and/or upgrading is my task.
Usually there are logged-in users, then I have to ask them (mostly via communicator) to please log off, because I can not modify with users in the db.
I would like to send these users a message via Access, like "Please log off from the db for maintenance blabla".

I already have created & run an Access database for around 12 users. I now am looking to create a database that can have at least 30 users. Each one with a unique user ID & password (Using a security file ".mdw") Users log into a front end on a network environment. Now...My question...Is 30 to large of a user base for Access in a network environment??

I recently made a database that we will use to allocate appointments between a team of up to 30 in 2 different sites. I have tested it with 10 people in the same site using it and have had no issues so far.
One of our managers wants to know whether it is likely to cause issues with network usage/congestion. When we introduce it to the other site. I told her it is unlikely, but went to our IT department for their opinion. I got a reply simply stating that Access is not intended for this sort of task, and is only designed to have a couple of people using it at a time.
I'd like a second opinion, because I don't think that answer is even close to correct. I'll describe briefly how it works and what our set up is.
The database has 2 tables, one that stores the details of the clients we call (7 fields), and another that logs each contact attempt (6 field) and ensures no 2 users get the same entry. I have split the database, with the backend saved on one of our networked drives, and the frontend will be distributed in an email. (at present it is just an unsplit database stored on a network drive, but I don't think this will work well when 2 different sites are using it).
I think data throughput will be minimal, but I don't know how I'd go about checking that. Would you expect any issues with this being used by 30 people simultaneously?

I know that tables have a max of 255 fields. How many can you add to a query?
I have a large database that is divided into several tables. When building the query to select all the data I will be way over 255.
Will this be an issue?
Thx!

I am trying to implement a username and password system on my DB. What I have done so far is created a table with username, password, permission level and datestamp. So when the db is opened, the form pops up and someone has to sign in. When they hit the 'login' button, there is a field that will populate the time in which they signed in. This will also allow me to see who is logged in. When they are finished, they will end up on the login screen where there is a close button. When they hit the close button, the field with the datestamp will be cleared. This will allow me to know that the user is no longer on the db. Here comes the question, if a user just closes access without hitting my 'close' button, my datestamp field will not be cleared. I have tried using the "onclose" event, but of course i used 'me.datestamp = "" but the form is already closed, so it says 'can not change the value of this field.' How can i clear the value of the datestamp field for a specific user when a user closes the program the "improper" way.

I am new to MS access. I need to know - how to set authentications to different users. i.e. i have made a switchboard containing login form, and other forms of the database. all i want is to restrict user from accessing my main tables of DB.
When someone wants to enter data, he/she can use switchboard but with the restrictions not to see anything else. only administrator or people with user ID and password can have access to entire DB.

The database: is for tracking computer issues (this part is complete), also I need to show the on call roster (mostly complete)... This will also have a time sheet that I need to be completed once a fortnight, however I would like it to auto populate the staff members logged information (I will get into that a little later).
Question 1: I do not want the users to log into the database, however I do want the database recognise who they are from their windows logon details.

I have developed a new database using Access 2003, which I need to roll out across various users. Some have XP, some Windows 7, and each of them has different size screens. I guess I will have to adjust the various forms to size to a particular users screen resolutions and sizes.
Is there any way of doing this within the database itself, or do I have have to adjust each form according to the local users PC specification?

Currently the system where I work is set up so that everyone has their own front end on the local network. I would like to change this because updating all of them takes a lot of time for me and skill level for users is too low for me to trust them with updating it on there own.
My question is this:
If I were to create a shortcut on everyone's desktop that linked to one front end would this be wise? I can't seem to get a straight answer from anywhere on the internet. I know most places say that it is better to have the actual front end on the staffs computer but that would make my job of keeping the database updated even worse because staff have multiple computers and this isn't my full time job.
If this is okay practice how many users would this be able to sustain? Currently we only have 6 users on the database with there own front end and it works great. I am planning on adding around 10 more users in the future but if needed they could have there own database as they are separate programs.

I'm an absolute novice at Access. I have a very simple (yet sufficient) database that lists our company's projects, tasks associated with those projects and when to invoice.
Our company consists of myself and my business partner. We both work from our (separate) homes. Our project files are stored in the cloud. This works well. We have investigated a server in the past, but found it to be cost-prohibitive and unnecessary for our business.
Is there a way that my business partner can have the Access database running at the same time as me, and make additions/modifications? I don't know how this would work in terms of updating/saving.

I have created an access 07 database and split it to a back-end and a front-end with linked tables.
I wish to deploy it an a network of 4 computers, 3 of which are running on XP. The back-end will be on a computer running on XP. Now, from the instructions I have come across online, the Back-end has to be located on a folder where all users have Red and Write rights!!! And I am thinking, if the users on this network can actually see the back-end since it is on a shared folder where they have all the rights, then does that not compromise the security?
Is there a way of linking to the back-end on a network WITHOUT the users being able to access the back-end?
