Import Large Xls (165K Recs)
Mar 1, 2006
I've been given a file with 165,000 records that was saved as an .xls file. I'm trying to import it into Access so I can view all of the records. When I try to import the file I get an error that "C:AllFiles.xls" is not in the expected format. I've tried the external data wizard and transferspreadsheet method.
I can open the file in excel and see the first 65,000 records. If I copy them and paste them into a new .xls file, I can import them just fine.
How can I get to the other 100,000 records?
Thanks,
Sup

I want to make a database of diseases (need to learn them for school and would like a serchable database on my smart phone for future reference).
Unfortunately spent a lot of time making hundreds of pages of word tables before i realized a database would be better. See attached image or pdf. Is there a way to import the tables to Access?
I need to preserve the hierarchic info in the nested bullet point lists. E.g. under treatment i might have a point called Acute treatment, with sub-levels, Step 1, Step 2, etc. with their own sub-levels. I need to maintain this relational hierarchic info.

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 quite frustrated at not being able to solve this problem in a Db I am developing for my wife. :eek: I have searched through a number of solutions to similar thread questions. I tried using "Distinct" in the SQL statement, Grouping using Max, Min, First and Last all without success.
So my db is a simple 2 table set up with a one to many relationship as follows:
tblPatient Details (RecNo (PK), Surname, FirstName, DOB, Postcode)
tblVisit Details (VisitNo(PK), VisitDate, RecNo(FK), Location, Category, Diagnosis, Drug1, Drug2, etc)
Whenever I run a query I am getting duplicated records of Visit information which should happen. However, I would like to have only one of the visits displaying (first or last doesnt matter.) The Visit No is a unique autonumber.
Can anyone help, any assistance would be greatly appreciated.

Here's what I'm trying to do:
Form A is used for data entry into SampleTable. On this form I have a some fields including these two: ReplicateA, LabBatchCode.
The database contains another table, IndividualSampleTable. This table contains two fields: ReplicateB, LabBatchCodeReplicateB.
When the user enters information into Form A, the data in fields Sample.ReplicateA and Sample.LabBatchCode are used to populate IndividuallSampleTable. But here's the twist: On IndividualSample Table, IndividualSample.ReplicateB needs to be autogenerated (I guess). Then the field IndividualSample.LabBatchCodeReplicateB is comprised of LabBatchCode entered in Form A, concatenated to the IndividualSample.ReplicateB field.
To make it tricker, the number of records added to IndividualSample table is determined by the value supplied on Form A in the field ReplicateA.
So, Form A could look like this:
ReplicateA: 3
LabBatchCode: CRBR05151998
IndividualSample table should end up with three records like this:
ReplicateB: 1
LabBatchCode: CRBR051519981
ReplicateB: 2
LabBatchCode: CRBR051519982
ReplicateB: 3
LabBatchCode: CRBR051519983
Hope this makes sense! And I appreciate the help!!!!

Greetings all! We have a mentor-mentee database that's been setup with a many-to-many design. We're storing essentially the same data in each table except for the field names. We thought we were good to go but one additional request was made to determine a count of employees participating in the program (regardless of whether mentor or mentee) in each section of the company. We don't want each person counted multiple times if they are both a mentor and a mentee, or if they have >1 mentee or >1. I created a couple of queries to pull unique empIDs from each table to narrow down each table BUT I'm stuck on being able to pull unique id's from both tables.
I first tried the unmatched query wizard from both viewpoints but then I don't get those cases where a mentor is also a mentee. In other attempts, I end up with a cartesian product. I've cruised through the queries section but haven't come up with any examples related to this type of situation.
I need a way to pull both unmatched records from each table while also getting essentially the first occurrence of instances where mentorID=MenteeId. I'm no SQL expert so if someone can think of a statement that would suffice, it would be greatly appreciated.

I have the following piece of code for importing the .csv files from a selected folder and then renaming them into 'imported & filename' if succesful and 'failed & filename' if import failes for whatever reason (bad formating, etc.).
The problem is that the first time it encounters a 'bad' file after another, instead of going again to the Error handler, the command
Code:
DoCmd.TransferText acImportDelim, , "Activitate", filename, True
gives me the default MS Access error, namely 2391. I would like it to go the the Error_handler again ang follow the course of actions and rename the files into 'failed' and 'imported'.
Here's the code:
Sub ImportActivitate()
Dim strFile As String 'Filename's
Dim strFileList() As String ' File Array
Dim intFile As Integer 'Number of files
Dim filename As String, sFullName As String, sFilename As String
DoCmd.SetWarnings False
[code]....
Also, how can I make the routine stop cycling through the files after I renamed them all?

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'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!

I 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?

How to get a large .txt file into Access. I know it has too many columns so I selected about 30 columns that I don't need to be 'skipped'. 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.

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 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?

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

I 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!
T.J.

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

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.

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.
Thanks,

I have a table with 140 fields (I know, this is too many). I have a date field that intermittently will not allow data to be entered. There is a pattern to the data it will not accept, but it seems to only occur in certain records and what it will or will not allow seems different in each case. The error I get when I try to save a record is: The search key was not found in any record. I've isolated the error to the level of the table. Have tried compact/repair, removing the index on the field, deleting and recreating the field. Nothing works. Help! :confused:

Hi,
To avoid the mind-numbing tedium of have to use make-table queries loads of times, is there a quick (probably VBA-related) way to split a large Access table, of about 350000 records, down into 93 smaller tables, based on a key code field that identifies each group of records e.g. GBW102, GBE999, etc?
Any help much appreciated.
thanks,
Alex
