Trouble! Replacing Characters In A Large Access Database
Jun 1, 2007
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:
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.
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)
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?
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?
I have info in Excel workbooks coming from various individuals. I take bits and pieces of data from each and the update an Access DB. Is there a way to simply replace the table in Access without affecting the relationships that the current version of the table has?
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 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.
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.
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.
I'm trying to use a banner ads .asp program called Admentor. My problem is that this uses DNS less connection and I can't get this working on both the pages showing the ads and the admin panel.
I know it's the path to the database that causes this. If I change this to suite the webpages showing ads, it work's, and if I modify it to suite the admin panel it work's. But not both at the same time.
Should'nt this path be relative to the sites root ?
when using this string, the webpages showing banners is working, but when clicking on these, the site calles a redirect .asp page that also uses this database connection. Then it fails, since this page is located in another folder in the site and therefore also gets another path to the database.
How can I get this to be a relative path working on all pages not been worried about folders, subfolders and correct paths to the base ???
We have an access Database stored on a server that until now was only ever accessed by the one user. Now more users need to access it at the same time. However when a second user trys to open the database the error message "File Already in use appears". I did not create this database so have no idea how it was set up. I think it may have something to do with being opened up exclusively. Is there anyway around this by creating a short cut or changing any kind of propertties?
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.
I 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.
I have a large .dat file which is run through an Access macro to produce reports. After a recent system change at work the format of the .dat has changed and now includes an additional bit of data which disrupts the macro.
I tried changing the extension of the file from dat to mdb to see if I could remove the additional column in access. I also tried changing it to a csv file as well but the file has a few hundred thousand lines and the csv file cuts most of it out.
Are there any other ways I can open this file in Access to remove this additional column of data?
I have a data where I want to create a query fulfilling the below conditions. Suppose I have two table: Table 1 and Table 2 If a value ex.98 (Table1) matches with the value with 98(Table 2),it should pick up my second higher value 103. suppose 103 is the next high value of 98 . Please see the data value.
misprepaid.asmvalue from Table2 Required Result Con 989898 then 103 if value of table1=98 then 103 from table 2 (next large number) 103103103 then 149 if value of table1=103 then 149 from table 2 (next large number) 149149149 then 175 if value of table1=149 then 175 from table 2 (next large number) 175175175 then 198 if value of table1=175 then 198 from table 2 (next large number) 198198198 then 199
I'm trying to import an Excel file into access as a table so I can use the data in other tables I am building. When I try to import to file, I get an error message telling me that there are over 255 columns and not all my data will be imported. The file is a report I pull from another system at work and it is very large, is there a way to get past the 255 column limit?
I am currently in the midst of conversation over at utteraccess.com about a large database project I am working on.
I will post the most recent updates here, but if you want to download the database for your own review, you'll have to go over to the other forum. By the way, this is NOT an advertisement. I am a real person with a real, significant, and immediate need of as much assistance as possible for this project.
Before I go on, a few things about me. Though I am in the legal profession, my technological background is very strong, including a high level of proficiency with MS Office apps with the exception of Access. I know my way around the program (the result of its homogeneity with the rest of Office), but have not made a real database in the past. I also do not know any programming languages.
I have recently indulged in an Access crash course of sorts, including some book and online study on things like planning, design, and normalization, but I am still having difficulty wrapping my head around making it work.
That said, the link to the other discussion is: [W W W DOT]utteraccess.[ADD DOT COM]/forums/showflat.php?Cat=&Number=1590364&page=0&view=collapsed&sb=5&o=&fpart=all&vc=1
Feel free to gloss over it to see how things have progressed. Below is a paste of my most recent substantive post. Any help anyone can give me is of great value to me and I really, really appreciate it. _____________________
Hi Everyone,
Attached is the most updated version of my database project for your review. I have also attached a sample of the output we would like to have for each product. This sample is not based on actual data, but it clearly shows what we are trying to achieve via a form of some sort. More on this in a minute.
The following changes have been made to the DB:
-Changed tblTrustProspectusVersion to include the appropriate data, based on our business model. -Added descriptions to all non-PK fields. -Created relationships to illustrate how things fit together. Note that these are NOT the actual relationships, but are for illustrative purposes to help everyone here (including myself) further understand how things fit together.
Our Business:
I am part of my company's legal department. Our team handles a number of different things primarily associated with Securities and Exchange Commission (SEC). filings. We have two major product lines. Everything that happens with one in this DB happens with the other as well.
Each product within a product line has certain features and other necessary information we need to see when doing our filings (see the attached sample output). These features and necessities include, but are not limited to, various statuses, various numbers associated with the SEC, various important dates, etc.
In addition, each product has a certain "fund lineup" associated with it. These funds are made up of two components: the name of the fund (aka "portfolio") and the name of the subadvisor to that fund.
Futher, each of these funds is associated with a certain Trust. The SEC requires us to send prospectuses to clients based on these Trusts, which, as I mentioned, are comprised of the said funds.
Basically, we need to be able to select a product from a drop-down list and have all of the aforementioned information populate instantly.
Before I close, one question with respect to my "tblProductFeatures". Like I mentioned, each product has a certain set of features associated with it. Each feature has a certain fee associated with it. These features come in four basic categories: Living Benefits + fees, Death Benefits + fees; Maintenance fees (just short list of the possible fees); and 12b-1 fees (another short list of fees).
Since the features can be so easily broken down, should I add them to their own tables?
Please consider this as you give your advice on how to acheive my desired goal.
I hope this makes sense.
And again, thank you all so very much for your help thus far.
I have 250 separate worksheets with a lot of data to put into Access. Problem is the data is 120,000 rows in each worksheet and a lot of duplicate date eg..DATE, NAME, TIME,are some of the column headings and there are multiple rows with same DATE or NAME. That is just how I received the data. I would like to transfer all records into Access as quickly and efficiently as possible.
I have a data file I am importing into MS Access 2010. One of the fields is a large text field. When i import that field into Access the text is getting cut off. How do I get the full text field to import without cutting off?
I have been trying to figure out this issue concerning the memo field in the database will only send about 255 characters. I am using the cmdEmail AssignedTo : On Click macro and the Message text and have two memo fields and only one will display and the one that does only displays about 255 characters
The message text ="Issue" & ":" & Chr(13) & [COMMENT] & Chr(10) & "Resolution" & ":" & [RESOLUTION] & Chr(10).
I have created a rather large data entry form for one of our departments which will be used to run a mail merge document. The merge is run off of a query of the form, rather than the tables themselves...I think that is what I've read is the right thing to do?
Anyways, most of it is working great so far but I've run into an issue where a few of the form fields are combo boxes. In access and in the query the data looks correct, but when you look at it in word (in edit recipient list) and after the merge, it will have a file path name instead.
So a combo box that has "Medical Plans and Visual Plans" in that field in the query, comes over saying "c:Users ameAppData
Ex: New Hires are provided information about Medical Plans and Visual Plans. Ex: New Hires are provided information about MeC:UsersbrooksAppData
It always shows the first two letters before putting the filepath name in there.
I have tried doing it multiple ways...a lookup to another table, lookup right in the field itself....get the same results.
I am trying to setup a webpage for people to update access 2000 db using FP2000 and DRW. I do not want update all fields in a record though - a couple of them are static. I have been unable to do this. I am using code lifted from another page and DB that does exactly the same thing for the update. I either get the error data type mismatch, or I should provide default values for all form related fields, or no records get updated. Is there anyone who can point me inthe right direction? Thanks, Tim
I have an asset database I am designing to manage our computer inventory and assets.
I am trying to get a DLookup to work with one of my forms that will auto-populate some of the fields depending on what is entered in to the ProductID field. For instance, Make, Model, Asset type...
My problem is that the string that returns contains special characters, specifically "#" and gives me the error message -
Run-time error '3075': Syntax error in date in query expression 'productID=EN371UA#ABA'.
My expression is definitely working, it just looks like it things it has something to do with date/time which it does not. Unfortunately, most HP equipment contains a # in the Product ID number.
Here is my expression -
Private Sub ProductIDCombo_AfterUpdate() Make = DLookup("Make", "productlist", "productID=" & [ProductIDCombo]) End Sub
Make is the field I am looking up from the ProductList table. The Product ID is the ID I'm looking up from the ProductList table to find the make. My problem is actually getting it to return the correct value of "HP or Dell or Lenovo". etc.
