Hi
I have a large database with many tables, forms, queries repost etc. These are stored named and displayed alphabetically, is there a way to place them in folders within access so it is easier to organise and locate as i am developing. Or do i just need to rename them all with a section title as the first part of the name?
Thanks
Hi
Many thanxs for replies, Like the idea of compacting.
We are traveling down the path of setting up a delete query.
This will hopefully delete the records but not the structure.
We are networked and a computer Warp2, writes data at Midnight to the sever, and then we use access on Windows NT to view the data.
We can then compact to maintain the database and not allow it to grow to 1.6 GB again.
Any ideas on the delete query thingy would be greatly appreciated.
:cool:
Many thanks for reading this post from a new starter.
Hi,
I am currently using a large Access 2002 database in order to generate various reports.
My two main tables are despatches and returns from which they hold around 1,200,000 records and 100,000 records respectively.
The problem I have is that the reports use various expressions within various queries to generate a single result (percentages per channel etc.)
This is obviously very time consuming and it may take up to around 10 to 15 minutes to get a result from a chain of around 5 queries.
Can anyone suggest alternative methods to generate similar results in quicker time?
(Please note that the tables can not be downsized and records can not be archived)
Many thanks
:)
Hi All, please forgive me if I am in the wrong forum.
I have a pretty good size (~6400 table and 700 Mb) single user application. It runs on XP home with office 2000.
It is a financial application (stocks and mutual funds). Each symbol has it's own table. The app ran fine when we were monitoring about 1800 symbols. Now that we are up to 3200, I am getting some odd messages from Access. It can't find tables and also says that tables are opened exclusively by other processes.
Although I do not use explicit transactions, it is like I need a "commit" or refresh of the user table catalog.
Each table has 312 rows (52 weeks / year * 6 years of historical data). So, for half the tables (3200) I do 312 Inserts ("Insert into tablename (col1, col2, etc) values (val1, val2, etc)".
Is there a transaction log that needs clearing? Is there a setting in Access that I need to change?
Any thoughts on my situation?
Thanks in advance
Is there a simple way of copying the same data down a column in Access similar to Excel with its Fill Down Column. I have tryed copying down a column and it only goes one cell at a time or if I copy 5 cells with the same data, I can copy it to 5 empty cells.

I have a table on which my records are organised in alphabetical order by one field.
On my form which uses this table as the record set the records are all over the place and it is a nightmare finding the record I want. I don't understand why it goes out of order in the form.
How do I make sure that they are organised using the same field?
hi i need some advise here. I know a little about Microsoft Access and I am trying to organise a database.I have a table called receipts with column of firstname, last name,total cost, deposit, receipt, receipt#, receipt date. I did a calculated field in query to find balance due. My problem is adding all the receipts recieved from an individual to subtract it from the total cost to get the correct balance due by each individual. (Remember all receipt on the same table)
Could someone tell me how to organise it to get balance due.
Thanks
I am trying to change a field lenght of a large database (access 97) It is at 50 right now and want to change it to 25. When I try to change it and save the table I get a error when the bar is about 3/4 the way accross the bottom.
Microsoft can't change the data type - there isn't enough disk space or memory.
then
not enough space on temporary disk
This is error 3183. In the help it says that the TEMP DOS enviroment variable location doesn't have enough space. (summerising). Now I have a 100+gb drive that isn't close to being full. I also changed the MaxLocksPerFile registry dword to 8,000,000 as my table has around over 3 million records. I have tried this on a xp and 2000 machine same results. Next I am going to try it on a 98 machine. I could do it by breaking up the table into 2 differnt ones and do each one individually but there is an autonumber field used as a reference number (I know I know). So that would screw up the numbering scheem (Yes I know there are ways arund that also). this database is about 400MB
Couple of questions
1. Is there a way around this? I have not found a solution on line yet.
2. Will lowering the field length make the database smaller (the data that is in there now is less than 25 charecters and the field is set to 50.) I have gotten mixed info on this. there are a few fields I would like to reduce.
Thanks

Hi there,
I've developed over the past 3-4 years a database holding data relating to workload figures for my place of work. It has grown to a large size (eg. one table holds 1-2 million records). I've been trying to run a particular pivot table based on the sql query below:
SELECT Tests.Test, Year([DAUTH])+(Month([DAUTH])<4) AS FYear
FROM Sets INNER JOIN Tests ON Sets.SET = Tests.[Set Code]
WHERE (((Sets.DAUTH) Between #4/1/2003# And #3/31/2007#));
When I try producing a pivot table using the above query it takes forever - has it running for over 8 hours last night - then access closed down with a runtime error. Does MS access have a problem with large databases? Is there any way I can improve the efficiency / speed of access with a download add-on? Or, will I have to resort to using something like MySQL on a LINUX OS which has fewer demands on system resources when using large databases.
Any help would be much appreciated. Thanks for reading.
Hello all. Would anyone be so kind as to help me out with this beginners problem. I have a lot a books which i'd like to sort into categories. I'd like to be able to select a category from a combobox on a form, and for relevant books in that category to appear in a listbox. Upon clicking on a particular book on the listbox, relevent info should appear on the form eg. date purchased,author etc.
Is it also possible to have an option to view all books from a particular genre in spreadsheet format embedded in the form, and an option to view every book regardless of genre. I'd then like to be able to print reports on each/all. I'm sure i'd be able to manage if someone could kindly get me on the right path with an example.
Thanks,
Richard.
Howdy,
I am trying to clean up one field of a large database. Currently this field has many records that are listed as "XXXX, Inc.". I am trying to find a way to change all of those to "XXXX Inc" in the entire database.
I saw raskews code snippet on changing multiple characters in a string, but I have to admit I have only use VBA in Excel before and having a hard time with the basics.
Does anyone have some code or ideas on how to do this or something similar?
:confused:
Thanks,

I have a form with a Treeview in. I have it populated from a self-referencing database using the following code.
Code:
Private Sub Form_Load()
Const strTableQueryName = "SELECT * FROM tblHierarchy ORDER BY tblHierarchy.Function_Parent;"
Dim db As DAO.Database, rst As DAO.Recordset
Set db = CurrentDb
Set rst = db.OpenRecordset(strTableQueryName, dbOpenDynaset, dbReadOnly)
[Code] ....
The database this is referencing is about 30000 lines and it takes ~4 minutes to populate this way. I know Treeview isn't really supposed to be used in this way however it's what is required.
Now I have come up with the theory that I will populate each node with children as its clicked to be expanded.
Uploaded my current treeview example ....
Will keeping your field size shorter result in a smaller MDB file?
Or does Access only use as much space as there is real data in its fields.
Way back in the dBASE III days, dBASE would pad all your "real" information with as many spaces as necessary to fill up your field. I suspect that the MDB structure is probably smarter than that.
Another question on the same topic - I believe there is a maximum number of characters in a record (4000?). Can your field sizes add up to more than 4000, as long as the actual data, all combined, never totals 4000...?
Thanks............

I have two datasets that I am using. They start off with similar information: sitename, siteprovince, sitecoordinates. They also have 5 more fields that have the same type of information. After that there are about 10 more fields with no overlap.
In the original dBase program they came from they were treated as one dataset.
The current structure I am using is Company, CompanyContact, Transaction, SiteDetails (the dataset I am asking about).
Is it better design to breakup the SiteDetails into SiteTypeA and SiteTypeB? I have everything working in one table, but I thought it might be more effecient to have two.
I have a split database, the front end is showing to be 20.5 megs in size but there are only 4 forms and about 6 querys. Can someone tell me how to find what is making it so large?
I did a compact and repair but it did not reduce the size??
Thanks..

I'd like to create a table with 240 fields. I know that the max is 255, however, I'm getting a message "property value too large" after I've created 114. Any ideas? All the number fields are byte size. Thanks!
View 10 Replies View RelatedI am currently operating queries in my A2K DB that are 35458 characters (~11 full sheets of A4 paper with 12pt).
It takes roughly ½ second for the form to load due to the heavy query that is also calling functions (calc'd fields) from within, but it works fine.
Are there any problems in this?
I think I heard somewhere that queries have a max length of about 2000 characters or so ... :o
I guess I have too many columns in my database and I'm getting the error message "Property value is too large" when trying to open the database table. When I was using Access 2000, I was still able to open the database but using Access 2003, the database will not open. Is there a way around this so I can open the table to fix it?

However it is just giving me the error that my file has more than 255 columns - with the 30 selected for skip - it should have about 230 columns.
View 7 Replies View RelatedHi all, apologies for the long post but this is a long nightmare!
Using A2k on Win2k...Due to roll out a DB today, just made my final tweaks and decided to compact/backup as have done many times before. It's not a split DB but it is secure so I copied the mdw onto my desktop and accessed it using a special compact shortcut which points to the desktop copy DB not the one on the network. When I compacted though Access went about it's business for a while and then threw up the dreaded "Network connection may be Lost" error message (roughly translates as "your database is nicely corrupt now") which I have had in the past when I tried to compact on the network. I've never had this error before compacting locally but anyway I tried again and same error message. I tried opening some forms and stuff and sure enought the DB was corrupt. No probs I thought, I can just go back to the original and start the process again. I used the normal shorcut to open the original DB just to check everything was ok and the same error message appeared with same problems. Minor panic ensued and I thought i'd got the shortcuts mixed up or something... I hadn't, Both DB's were affected.
Next option. Create a new DB and import all the objects. I did that and re-set all the permissions and the "Network Connection Lost" message dissapeared but some really strange things were happening. Forms opened but the buttons on them would do nothing. Then the forms Close button didn't work and the database wouldn't close.
I forced my way out of the DB and re-started my machine. Couldn't even log in to windows. Now at another machine and can log in to windows but DB is still having same problems. My instict tells me that the problem is something to do with the workgroup file becuase how else could compacting a copy corrupt the original? The only common link is the mdw.
Should I re-create the mdw and then try opening/importing the DB objects again? Or is there any way I can un-secure the DB and then re-secure it later?
Any thoughts would be much appreciated.
Thanks, Tom
I have a database that keeps track of training hours for each employee. The Training Length is formated as Short Time. I just figured out that short time can only go up to 23:59:59. Some of my trainings will be over that. Does anyone know a way to get around other than splitting up my hours and Mins in the table?
View 1 Replies View RelatedI have a large search form, in which I am building a query in the code.
I went to compile the code, and was suprised to receive the error "Code too long for procedure". I had no idea there was a limit, but now I know.
So, I believe I will have to break this code up into chunks, stored on at least one if not more code modules, and call the functions.
To do this, I would have to pass the values entered into the form, to the code module. Build that portion of the query Where Clause, and then return that string value back to the code on the Search form.
Has anyone attempted this before? If so, could you give me a small example of how to pass a value from a form, to a code module, process it on the code module, then pass a resulting value from the code module back to the code in the form.
Thank you for your time!

I am using MS Access(2000) as a front end to a MS SQL2000 DB. I set up a table link to one of the tables in the SQL server. The table I am linking to has 242 Fields in it. The table shows 21888 rows of data.
In Access, when I set the record source in a Form to this linked table and go to run (Form) view, I get a "Record to Large" error.
In the SQL table - there is one varchar field that is 17 in length. There are about 5 char fields and the rest are numeric or date.
My questions are:
What is causing this error?
What would be a good work around or other possible solutions?
Thanks.
This number is too large [220020220020] for a field in my table. I currently have it set to Long Integer. What's the proper setting for a number this large?

Hello. My database has around 6000 products, and as time has gone by, the database has got bigger and bigger, more and more text - its now a rather large 16MB. Now, everytime i make a small change to it and upload to the server, it takes me about 8 min uploadeing it. Not that bad, but if i have to change 3-4 times a day? Also, it wipes out the website during the upload, which is not that great. Is there someway to compact the access database somehow? Thanks.
View 5 Replies View RelatedI am writing a vba procedure to updating some records in another Access database.
rsAccess.Open "SELECT * FROM AI_Table",conAccess, adOpenForwardOnly, adLockPessimistic
rsAccess!OCRExist = "Exist"
rsAccess.Update
it has about 3 millions of records in that AI_Table. In the procedure, I perform some calculation and put the result into a TEXT(50) field in the AI_TABLE. As it was updating the records, I could see the size of the Access database file (the one contained AI_Table) grew very quickly, almost 1 MB/sec. I am pretty sure I am not adding that much data. If I stop the procedure and packed the database, it shrunk a lot.
I am just wondering if there is anything wrong with the way I am locking or updating the records.
Thanks,
