General :: How To Get A Large Dat File Into Access
Feb 3, 2013
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 am importing a delimited .txt file that has a number field. A value for a record coming in is 36,767 and Access is not accepting it. If I redefine the field as long integer or as double, I can manually update the record, but as soon as the file containing the record is imported, the field reverts back to integer.
How do I format the field with VBA so that Access will accept the value and not revert to integer?
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 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 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.
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.
I often create contract using mail merge. I have an access file that I want to use as data source for word file. But it does not automatically.
Please download the attached file !
If there are 1 customer and 1 property, I do not need to do anything. Conversely, if there are many customers and many properties, I take time to manipulate.
Firstly, I open the word file. I have to copy and paste paragraphs that I want. Highlight of the original paragraphs is blue.
Secondly, I click 'Insert Word Field' -> select 'Next Record'.
In short, I wish to use VBA in access file to automatically perform the steps that I have outlined.
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 have a large file, more than 2 million records. I am accessing it from a form using parameters supplied from a combo box. There are 79 different parameters in the combo box that each normally access their proportionate number of records, about 40,000 each. This works well. With the table properly indexed, I get the 40,000 records selected within two or three seconds.
However, sometimes I want to access all records. In this case the operation takes forever. So, if I use the criteria in the query:
[Forms]![CriteriaPassingForm]![Criteria] the records are returned very quickly.
But, if I use the criteria:
Like "*" & [Forms]![CriteriaPassingForm]![Criteria] the return of records takes minutes instead of seconds.
Within the combo box I have one criteria which is 'null'. This does not match anything in the query, so according to the 'Like "*"' all records should be returned, which they are. But why does it take so much longer?
I'm thinking it has something to do with the operation of the index on the field I am querying.
I'm having a problem with mdb file size. I'm importing a large amount of data from a number of tab delimited text files via a simple transfertext function. The process goes: empty the tables in the database, then import the data into the tables.
All this works fine, but the file size rockets to over 1.5Gb. When I then compact and repair, it goes down to 420Mb. I'm not deleting and recreating the tables, and at no point is there 1.5Gb worth of real data, so what's causing this?
N.B. I realise I can call compact and repair following the import, but this is going to take too long as they are user-initiated imports.
I am attempting to create a metrics analysis table from another table. What I would like to do is copy the structure (only) from table 1 into a new table. Change all the fields in the new table to text (except for an ID field which would be an autonumber). Then run a seperate group by query against each column, counting the values in each group (i.e. first query would have two fields The grouped column and the column count.
Once I have these values I would like to concatenate them (with the count in parens) and then push these values back into the new table under the appropriate column.
My code does this. I basically loop through a recordset that runs to each column/field groups and counts and then Edits the new table with the concatenated data.
My first table is 170 fields and 38K records. The issue is that it's too much for Access to handle and it blows up (on field 123) Telling me the File is too large. The file does explode to 1G. Then I can shrink it back down to 67mb by running a repair and compact... and then run the the data for the rest of the fields in that table. When I compact again I get about 80Mb.
So now I have two tables, both with an ID field... so I try to link them together (via a make table query) and meld them into one table... but it keep running into that "File Too Large" issue.
How can I have two tables in a database file with a combined size of 80Mb, but when linked together are too large for the database file? Does it have something to do with having all text fields?
I looked up the limits to MS Access and the field count doesn't appear to be an issue since it's nowhere near 255... So what's the problem here?
The file was converted from excel. It is in Datasheet view. I select the first column and clip on the Ascending choice under the Home Tab. It works but leaves a large gab of blank rows. I go to the Database Tools tab and check Compact and Repair Database. The file returns to the original unorganized list.
I am trying to find a way to extract an email from a large text file that is an output from our email system. I would like to be able to extract the email address using a query or collection of queries. I have been able to extract all of the text that contains the @ symbol. From their I created a query expression:
Mid([field1],InStrRev([field1]," ")) that captures some but not everything I need.
I'm wanting to create a way of searching through and displaying a large number of pdfs. These will be of different lengths and most will have images embedded in them. Each pdf will be categorised using a variety of fields to enable fairly sophisticated searches. I then want to link this database to a Joomla CMS website.
I pulled a report from this website my company uses and it has around 7,000 orders and a corresponding employee to each record. Since each employee has around 20-50 orders, I was wondering if there was a VBA code or different Access tool to randomly select only 2 orders from each employee, thus reducing the data set from 7,000 to a more manageable number?
I'm using access 2010. how should I share the access file I created that will be the best way?there are 20 users that need to add/edit/view the data.I read in some places that I need to do share on options and some said that I need to split the file to data and front file.
Any issues with using Access 2010 to edit an mdb file..I know there are backward incompatibility issues with 2007 and 2010, but these are both accdb formats.
I use below simple command line to start a macro in my Access database. Usually all works well. I start my bat file, command is executed and macro does its job.
However it always fails if I have a session of Access already opened even if it is a completely different database. If I use below then it opens another sessions of Access but does not execute the macro. I need to go into the second session and run macro manually. It works fine then.
I have 3 sets of MS Access File (NEDA, RDC,& Summid) built with the same sets of structures. Originally at MS Access 2007, but now I'm using the built in 2010 version for Lenovo Flex 2.The table consist of:
*Chart of Accounts *Journal Entry Voucher Master File *Journal Entry Number Master File *Supplier Master File Queries are the same (links, designed, etc...) Forms are also the same (links, designed, etc...) Reports are also the same (links, designed, etc...)
The difference for these three file is the Journal Entry Number because each file requires a different JEV format...Example:
-For NEDA it should be NEDA-Year-Month-Number Series -For RDC it should be RDC-Year-Month-Number Seried
Laslty for summid it should be Summid-Year-month-Number Series and separate transaction listing for the purpose of calling data for the report, such as List of disbursements and trial balance.But for these three MS Access file, Chart of Accounts and Supplier Master File do have the same set of data. That's why whenever a data is not available I am encoding the said information in each MS Access file (inputting the data three times).Example:If an asset account such as Office Supplies is not available, I will input in the Chart of Account Form for NEDA, then RDC, then Summid.
Question
Is there a way where I can unified the Chart of Accounts and Supplier Master File into one but still can entry/edit the same in each MS Access forms. Also can still link to each queries, tables,and reports?So that I will encode data one time only and save space.
I was successfully using a front end and back end setup for the past two years. Today I needed to push through some changes and "deactivate" the previous back end database and setup a new back end database. The new back end database has been sent; however the front end is not recognizing the back end database anymore. I need to re-link the existing front end to the back end database - I cannot import the front end into a "fresh" file because I put a password on the VBA Editor.
Is it possible (using the menu or VBA code) to find out the size of the objects in an Access database file?For example if the .accdb file is 300Mb, is there any way of comparing the size of the numerous tables/forms/reports/queries etc, that make up the database?(I know that if I created a new access file and imported the objects from the working database that could give an indication but that would be quite a repetitive process).

When you select open it does retreive the file in PDF.However, our customers are not very likely to open it because of its File Name.I do send the document to PDF file 1st.I am a carpenter by trade just trying to make my business more easier to run from the office and keeping up with the times.I receive emails from Vendors all the time,I am an avid user of Access since 2000, I barely understand VBA code and often copy from samples and/or researched code.
Here is my Code: Private Sub Command198_Click() Dim strToEmailAddress As String
Okay so I created a database inventory. I know I can turn it into a "application" making it a EXE file. I was wondering after that being done could I burn that into a CD? So it would boot from the CD. Pretty make it work like a program application as in word, excel, etc..
when I open a pdf through access weather it is by hyperlink or attachment it always opens the full size of my monitor, if I open a pdf outside access then they open ok , how do I set the size that access opens the pdf the size I want.
I just upgraded to Access 2010. I was able to solve all migrational issues, but my custom ribbon is showing two File tabs, one that I created and the default access file tab. How to get rid of the default File tab or at least disable it?
