Hello, I am new to this forum and hope someone will be able to help me.
I understand that when querying using a split MS Access database it retrieves all the data to the client machine and then applies the criteria (hope this is correct) at the client side.
If I were to link to Oracle XE tables via ODBC, does a query using these linked tables still bring across all the records to the client or will it run the query on the server and just bring down the records matching that criteria?
This post is really aimed at someone that has experience of network databases and the problems they can pose but if you can help at all that would be great!
I work for an insurance company and we have created a database for registering complaints on. The one we currently use is a single .mdb file which can be shared by up to 60 people at any one time. This is creating a lot of problems when the queries and some VBA code are run. I therefore made a server file which is just an mdb file with data tables in and NO forms or queries. This file is stored on a shared drive on the network server. We then created a client file which contains all of the forms and queries and code. This file contains linked tables to the server so when data is entered into the form, it "Sends" it to the server mdb file. The client is installed on each of the local machines c:. The problem with this was that if we made a change to the database, we would need to reinstall the client on every single user pc. This would of took ages. I therefore made an auto-update function that checked the version number on the server and if the server number was greater than the client number, a simple .bat fiile was run which copied the updated client file from the network to the relevant users local disk. The problem we have now is that our IT department are concered that if we make a change to the client and all the staff log in at 9am for example, it will start doing multiple copying of a file around 8mb in size to around 60 machines. They are only running on a 2meg pipe so this could cause some problems. We are not looking to change the client & server idea but does anyone know if this will have a big impact and infact if the updates for 60 machine is the equivalent or lesser of 60 people sharing the single file i mentioned earlier. If the IT dept are happy with 60 users accessing the same file at the same time, which they currently are, why are they unhappy with it updating these machine using the new method.
Would really apopreciate any thoughts anyone has..
I have a problem with my query which works fine prior to upsizing to SQL Server. Now I have an Access Front-end with SQL Server (2005) back-end client/server setup. This problem has bugged me for over one full day and I can't find anything that seems to solve it.
The error that comes up is this:
Run-time error '3146': ODBC--call failed. [Microsoft][ODBC SQL Server Driver][SQL Server]Incorrect syntax near '='. (#102)
The line that's producing the error is a DoCmd.RunSQL "SELECT tblPBC..." The full statement is below. I can't seem to see anything wrong w/ my syntax below....
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.
Brand new on here and desparate for some help and guidence.
So far with Access I have just used it as a store of addresses to mailshot prospective clients.
However, I now need a more complex database and this is where you might be able to help.
First things first, most of my clients are in universities. This means that I can be used by more than one person in more than one department at a university.
Does this mean I need to do three tables:
1/ "University Details" which gives the address details 2/ "Department" storing the departments of the unis we work for 3/ "Client" Name of the client(s) in that department.
Hi, we use access for localisation in our application. The business object which accessess the access uses DAO connectivity and we often land to "Too many client tasks" problem.
is it wise to change the DAO to ADO? if so the above problem will go off? what are the chances that the problem still persists?
is that access has any limits on the number of connections? like 64, 255? or is that ADO/DAO has any limitaions on the number of concurrent connections to access DB?
I'm making a pop-up form for a certain of clients who require advocacy. I'm including a screenshot.
The thing is I don't necessarily want the form to go to a particular record, but rather be null until lastname/firstname field is filled in. I've written code to look up if there's already a client on the file and thus use that file, but am stuck when if there's none, and it's a new client, how do I make it so a new file is created?
Currently, the lastname and firstname's record source is a query looking up the corresponding fields in the related table.
Also, should I do something special for form's load property to ensure that no new record are created until lastname/firstname has been filled in?
Private Sub LastName_AfterUpdate()
If IsNull(DLookup("advocacyid", "advocacy", [me.lastname=advocacy.advocacyid])) Then DoCmd.GoToRecord , , acNewRec Exit Sub Else Let Me.AdvocacyID = DLookup("advocacyid", "advocacy", [me.lastname=advocacy.lastname]) Let Me.FirstName = DLookup("firstname", "advocacy", [me.advocacyid=advocacy.advocacyid]) Let Me.LastUpdate.DefaultValue = DLookup("lastupdate", "advocacy", [me.advocacyid=advocacy.advocacyid]) End If
I have a feeling that my problem is easy, but I have been in a panic over this project, that I cant think too straight anymore (I think I need a vacation!)
I have a simple form for tracking employee activity, such as rehire, death, orig hire, exc. This works find, except they now want to be able to make changes to staff details like new job title and such. On the same form. They don't want to change forms.
So I added a subform that connects to the Staff Detail table, using the Clock# that exists in both tables.
When the form is open, user must choose employee from drop down, once choice is made the clockno on the main form fills in, however, the subform clockno which it connected to the main doesnot update- unless, is you go into design view and then back to form view, the subform fills in with the right info, you can even use it in quierys -- However, if you change the employee in the main form, its clockno will change, but not the subform, you have to go the design view again. I have no clue. HELP
Consultants need to be able to log-in when they are available and be put in rotation. Agents need to be able to select the next available Consultant. I also need there to be a waiting list. I would like to be able to run reporting on Time on Waiting List, Time with Consultant, etc.
Is there a simple way to do this? I would appreciate if someone could point me in the right direction.
I want to create tables with clients and another table to populate multiple orders for each client. How these tables will look like and how to create one to multiple relationship.
Hi guys. I am trying to help a client regards an un-supported access database. They have a DB that is shared across a network (only have experiance on database on single client, never set up security etc....). The DB is installed on the Server. The DB is access via a mapped network drive. The Database folder contains the following files: MKC Clients_Quesries.mdb MKC Clients.mde MKC Clients_.des
On one machine the MKC Clients.mde is launched and 1086 records are visible. On a second machine the same MKC Clients.mde is opened but displays only 977 records?? An I missing the obvious?
I have created a db and am having serious problems, the size of the complete db is 3mb, and when split its 500k, the trouble I am having is that when putting the db on the network server and you try and open it based from home it takes so long for both the full db and the split.
The main db has one page that all staff need to see and have a quick response when opening on VPN client. The form I want to open has a combo box that lets the employee select the company and all the information updates on the form.
I tried making a page in acces to do the same thing but having problems
Is this possible what I am trying to do or is there an easy faster option.
Right now i using client server application using - Frond End : Ms.Access + Winsock with UDP protocol. ( This program like Yahoo Messenger ) - Back End : Sql Server
I made this program for Remote Trading.
every second server or client will be send data. Sometime Server send data only to specific client, so when client logon to application, I save the IP number and after logout i clear the IP
the problem will be happen when the computer client Hang, server cannt send a data to that computer, and waiting for ever until server hang too after that all client will be hang.
and the question is How to check status computer already ON or Off i mean before server send data, server will be check status computer with that IP, If status computer On then True else False, so if computer client off, server don't need to send data.
Firstly, I apologise if this has been posted before. I have done a couple of searches of the forums, but can't find what I'm after... and being new to access, I'm finding it hard to know what exactly to look for. How to even explain what I want is difficult!
I am designing a database for the clients we deal with a work. It started out as being a database of 'post' and correspondence, so the Idea was, we'd have a databse of all the clients... and by selecting their names, it would bring up a list of all the letters that have come in for them. I have managed this part fine - probably basic, but fine.
What I would like to do, is expand it to more than just 'letters'. Each client has done a particular 'work' with us, and each client has particular details that are unique. For example, a client will have made certain transactions through a bank account.
I hope to be able to click on a client, and have a screen or page pop up with details and comments about that particular client. I have tried hyperlinking but that doesn't really produce what I'm after. For example, I tried creating a "report" with a page for each client, so that I could have comments for each client - hyperlinked to the table. But all it does is link to the "whole report" and not a particular page for a particular client.
I'm sure this is sounding really confusing: I have a client named "Peter Litman". His name and details are within a "client" table (listing all clients). I hope to be able to click on his name (or row) and bring information (comments, details etc.) about him. I thought this could be some sort of "pop up", or link to a special page. ??
1. Client Info table which contains the following fields: Clientid LastName FirstName
2.DatesDistribution table Clientid DateAttended
The relationship is one to many for these tables.I have been trying to create a query that will show the following:
Clientid LastName FirstName DateAttended (where this field only shows the most current date that the client visited)
Example: ClientInfo has 2 records:
Clientid=jsmith LastName=Smith FirstName=Jim
Clientid=tjones LastName=Jones FirstName=Tom
[code]...
I have tried grouping the records in Client Info table to get distinct names and using a Last function to get the most current date with little success.
Am looking to do a treeview type of search to hyperlink to client file/folders on my network. This way I can hide the main file source location in the network and files can just be accessible via Access program search.
So far I found this link [URL] and the 3rd bottom option seems to be the most promising but I cant seem to figure how to accomplish the hyperlinks.
I am creating an employee database for a client. The employee table has a performance column for each employee, and my client wants to be able to choose from four performance codes - Excellent, Good, Average, and Poor. They want to choose these descriptions instead of typing them in each time. How can I make this happen?
I currently have details of my clients in a table called tblSites, this tble includes a field with an email address. I currently produce a invoice which is automatically saved as a pdf and an email generated with the invoice attached. However, a few clients do not have email addresses (these are sent by post). My code (see below) will successfully produce the email with the attachment, but if the client does NOT have an email address in the tblSites it comes up with the "Invalid use of Null" error. What I want it to do is continue the process of just saving the invoice with a Msgbox stating "This Client does not have an email address etc etc.
'Save Invoice as PDF and annotate Invoice Number, Date and site name
Dim StrFile As String Dim slSQLString As String Dim rsEmailAddress As Recordset Dim slEmailAddress As String StrFile = "C:Redwatch Invoices" & Forms!frminvoice!txtInvoiceNr.Value _ & "-" & Format(Date, "dd-mmm-yy") & "-" & Forms!frminvoice!cboSiteName & ".pdf"
I am working on an Insurance DB.. I have two tables tbl_Clients and tbl_PolicyDetails with a One-Many relationship.. tbl_Clients have the Clients basic info, Name, Tel, Address etc. The tbl_PolicyDetails have the details of the policy for the customer like Start date, policy term, amount they pay, policy status etc. Policy Status can be any of the following Quote, Active, Suspended, Lapsed, Cancelled, Terminated..
One client can have many Policies.. When one policy finishes (like when cover upgraded/downgraded/any changed their insured property address etc.) we categorise them as Termination of old policy thus the client will have a New policy.. At any stage we only need the newest policy per client. My problem now is I need to list all Clients with policy status Active, Suspended, Lapsed, Cancelled..
Code: SELECT tbl_Clients.cli_ID, tbl_Clients.firstName, tbl_Clients.address, tbl_PolicyDetails.policyCover FROM tbl_Clients INNER JOIN tbl_PolicyDetails ON tbl_Clients.cli_ID = tbl_PolicyDetails.cliID_FK WHERE tbl_PolicyDetails.policyStatus = "Active" Or tbl_PolicyDetails.policyStatus = "Suspended" Or tbl_PolicyDetails.policyStatus = "Lapsed" Or tbl_PolicyDetails.policyStatus = "Cancelled";
Code: cli_ID firstName address 1 Paul Bournemouth 2 Mark Bristol 3 Lauren London 4 Caryn Devon
[code]...
When a Client wishes to Cancel a policy it is not Terminated, the policy status is just Cancelled.. Similar to Lapsed policy, if the policy hits 30 days of no pay then it is passed on to a Debt collection agency.. If in future the Client comes back a new policy is generated for both cases.. So in this case Client Lauren and Caryn will have been repeated twice, in the report I am trying to generate (based on the above query).. I do not wish to display the Cancelled policy if the customer has another policy which again can be Active, Suspended, Lapsed, Cancelled..
Code: cli_ID firstName address policyCover policyStatus 1 Paul Bournemouth PDB Active 2 Mark Bristol PDB Active 3 Lauren London PDBCH Suspended 4 Caryn Devon PDE Active
I have a form for rentals where I have fields for car details and for client details. I have a list box for clients so that when I enter the Client Id I automatically get all the records filled out on the form, from the clients table...
This works but the problem is that sometimes I have a new client who rents a car that is not on the database so I insert the client details manually on the rentals form without filling in the client ID as this client does not exist on the database.
The problem comes when I want to save the form it wont allow me to leave the client ID field blank... I imagine this is because of the relationship...
I am trying to print a report for a specific Client. There are several routing records with dates. What I want to do is print the report for a specific Client that is in the primary table and a Date within the routing table. Each routing record has a Date field.
One client can have many routing records. Example: John Smith in client Routing record in the Routing table. I want to report on one Routing record with a specific date.
The Setup: There is a clients table, a property table and a jobs table. Each client can have multiple properties and there can be multiple jobs done on each property.
The form: I created a form that uses a drop down to select the client, once the client is selected the subform shows the properties for that client. I can navigate through the properties to select any of the required properties and on this same subform, there is a button to open the jobs related to the property selected.
The problem: The form and subform work fine. The last form (the button that opens up the jobs) works ONLY IF there are records available. If there are no jobs for that property, it doesn't allow me to enter a new record. I'm pretty sure that the issue is because the jobs form has a query record source that uses all three tables linked (I'm pulling the clients name from the clients table and the property name from property table).
What I need is some vba coding to check if the recordset is empty and if it is then add this entry. Also, I'm not sure if this should add this code to the button or on the on_load of the jobs form.
I'm creating a Dating Database on MS access, Now I've been given the attributes for all the tables. They are five (Client, Hobby, Meeting, ClientHobby, ClientMeeting)
Now I'm needed to create a form which allows me to enter the client data + at least two interests and their age calculated from their DOB. Seeing as I was only asked to put DOB in the actual Client table, I thought I'd create an Age query and then make that form out of the Age Query. (I already successfully managed to get the Age out of DOB in that query in a field of its own)
However, how can I add the hobbies field to that age query so I can finally create the form that I am required to do?
Second, I am to create a query which will be used for ‘matching’ clients. The criteria that you will use are: gender, age (using a range e.g. 20-25), interests/hobbies and city/town, this query ill be used to create a report which lists all the clients who match the entered criteria. How am I to do that?
I have completed a database for a company with 60 000 clients and over 100 000 job records.
The database works at very resonable speeds on the Server computer, or the computer on which I installed the back end of the database.
Each of the other 3 computers on the wireless network, have a local copy of the Front End on their machine, and reference the Back End (BE) on the server computer.
Each of the Client computers have varing speeds when accessing the BE, some as slow as 10 minutes for a simple search, filter or just loading a form.
What can I do to improve performance across the network?
Do I need to install additional components on the other computers to improve the db performance?
We are using MS Access as the backend to our application which has been written in delphi and have run into a problem that we have not been able to solve. Hoping someone has run into this before or any suggestions are much appreciated.
The problem:
MS Access runs slowly for client PC's after a update or insert.
- I am using ADO to connect to the Access database, which is using the OLEDB for ODBC Provider. - The application I have sends queries (both select and update) direct to the database (ie client datasets are used). - When only select queries are sent to the DB the response time is fine. - When an update or insert query is sent to the DB the response time of the PC it is run on is fine. - When an update or insert query is sent to the DB the response time of any other client PCs running the application take about 5 to 6 times longer to run queries than before the updateinsert query was done. This is the issue that I am having. - Any client PC's that display this slower response time, can have their response time returned to normal by closing down the application and restarting it. - No more than 3 PC's connected at one time to the DB. - Maximum database size of 150MB. - Problem occurs on various network setups, including domain and workgroup. - Problem only surfaces for users at times well after any application updates have been applied (ie several weeks after, and then once the problem starts it continues). - It does not occur for all user sites.
I have tried and thoroughly tested the following to no avail... - Applied all the latest microsoft updates - Closing and re-opening the ADO connection after updatesinserts - Changed the ADO provider to Jet 4 - Saving the DB in Access 2000 or 2002 format - Set the Default record locking to 'No Locks' and 'All records' and 'Edited record' - Used 'Open databases using record-level locking' selected and unselected - Many application techniques (using delphi) to work around the issue. Many of which have indeed improved general response times, but have not resolved this particular issue.
The only thing I have tried that has resolved the issue is... - Upsizing the database to SQL Server (Unfortunately this option is not a viable one for us at this stage, so I need to find a resolution to it while still using the Access DB).
