Custom Data Type
Jul 12, 2005
i am creating a database that will include four (4) tables that need to have an autonumber as a primary key, but i need that autonumber to be preceded by a letter (one letter for each table). i am creating forms for the users to based on these tables for users to enter data. please help...i'm running short on time. thanx!
the database i'm creating will be used to store city issued permits. there a 4 different types of permits that can be issued, some w/the same info (i.e. contractor, owner) and others with different data (certain permits are only issued for a specific # of days, others require a tap or meter size, etc.). i have separate tables for the contractors, owenrs, and payments, but each payment needs to be associated with a particular permit #. for example: check #3 from john doe contracting is associated with permit # m123, or h123, etc. that's why i decided to have a separate table for each permit type. i was attempting to avoid data redundancy. i also need separate forms for the users to enter data into as per their request. i'm open to suggestion if you have some other ideas. thanx in advance. :confused:

I have a field in a table that is comprised of mostly numerical data but some records are text.
I want to convert this field to numerical only and make a new field to put the textual data in.
However converting the field will delete the textual data. What is the easiest way to convert the field but save the textual data AND append the textual data to the SAME record that they were in originally in the new field?

I have a table in the Access DB which is structured this way:
ITEMID
FIELDNAME
FIELDVALUE
The Key is ITEMID,FIELDNAME
I need such a configuration because the items I need to store can have whatever fields the user could like. A simple example of the data contained could be:
ITEMID;FIELDNAME;FIELDVALUE
1;FIELDA;1111
1;FIELDB;2222
2;FIELDA;3333
2;FIELDB;4444
I need to load a datagrid in VB.NET displaying a table like this (according to the above example):
ITEM;FIELDA;FIELDB
1;1111;2222
2;3333;4444
I used to just load the data from Access and then build the grid directly from VB, but the records are becoming too many and this approach is just too slow. I was thinking about creating the table I need directly from a query, and then loading the result in a grid; however, this is something I'm having problems doing. Could anyone help me? Thanks.
Just a couple of notes:
- not every field is necessary present for each ITEM, so I need to handle the possibility of DBNull entries for some fields.
- If it can help, I know which fieldnames I can get before querying the DB

Hi,
I have a Form which contains a datasheet and I have some code which allows users to custom sort this datasheet. Another table based on this datasheet is then exported as a csv file.
However, the data is obviously not exported in the same order as the datasheet and it is quite critical for the application to be a sucess that it is exported in the custom order chosen by the user.
I have done some re-search, searching groups, forums etc and found the solution of having a 'sort column' in the table the datasheet relates to, I can then use this in the query that exports the data. My only problem with this is I had to manually fill in this sort column in the datasheet, once I had decided upon my final sort order. Is there anyway to fill this column automatically based on a row's position in a datasheet?
Many thanks in advance

I am working on a project where I need to upload selected data from multiple sheets of an excel file. Here is an example of what I want.
1. I want to create a table in Access with around 10 columns
2. Column 1 should be populated with the date field found in A2 cell of sheet 1 of the excel file
3. Column 2-5 should be populated with the columns B2-E200 in sheet 2 of the excel file.
4. Columns 6-7 would be populated based on values from columns 1-2 of the table. Basically Column 6 should be Column 1 date plus 60 days.
5. Column 8-10 would be user generated after the excel is imported and the user should have the ability to attach around 5 files to each row.

I’m not an expert in Access and hope that someone can help me with my problem. I have about 20 fields of Yes/No data type.
E.g.
StudentID- Tex
Science – Yes/No
Math – Yes/No
Biology – Yes/No
Chemistry – Yes/No
Economics – Yes/No
...
I would like to create a parameter query (without using form combo box) where when I run the query, it would prompt me for the subject name. Let say I keyed in Science, it would list out all the StudentsID who took up Science only (with a Yes) and the other subjects.
Pls help.
Thanks.

For keeping record of provient fund, I have made a access/(or excel) database with many fields like ID, Name,contribution for months eg March, April,..to..,Feb,etc.It contains 50 records.
Now I have to print the provident fund statements of my 50 friends. This statement consists of some text language and some data(It is a word form letter document).The statement also shows some data which has to be calculated from the data of database eg grand total, cumulative total, interests etc.
Now I want to print the statement for all or selected no of people. What I want is to make the statement proforma in another excel sheet and then merge and print the statements for selected no of persons eg for ID 1 to 20, 50 to 70 etc. I do not want to make statement in MS word and do not want to merge it there, but I want to do it in excel just as we do in MS word mail merge.
Pl help me how can I do it in access/Excel? Can i calculate in word or should I calculate before hand in access before merging data?

Some fool has chosen number for a date column and the date data show up like
8031976
12022001
If I just change the data type back to data, it's going to delete a lot of them.
Is there a way to make the change and preserve my data?
Thanks in advance.

Hi,
Trying to get back into Access after a long time, just need some refreshing :) tips.
I have 2 tables, one of the tables stores titles (mr, mrs, etc). I tried using the 'lookup' data type to link the data from the other table. This however stores the field as a number and causes problems on my form as only a number is shown rather that the text.
What do I need to do to resolve this? :confused:
Thank you.

Custom filter I'm trying to set up. I have a data full of records with multiple columns and a form linked up to it. The form has a search box that works as well as navigation buttons.
Currently I am trying to get a filter to work. The filter will use up to five combo foxes to narrow down the fields, then return the filtered records after clicking a button. The button itself is where my code is. My issue now though is I cannot get the filter to work if I try to use more than one combo box.
The code I have at the moment is as follows:
'------------------------------------------------------------
' cmdApplyFilter_Click
'
'------------------------------------------------------------
Private Sub cmdApplyFilter_Click()
Me.Filter = "[Asset Group] = " & Me.cmbFilter1 & "" And "[Location] = " & Me.cmbFilter4 & ""
Me.FilterOn = True
End SubThe current error I am getting is Error 13: Type mismatch. I also know that the And might be the cause but I cannot change it to AND: it keeps changing back.

It is my understanding that a custom macro was built to pull text data from a file and import it into Access in the appropriate fields. This macro no longer works and will return the following error message:
"License information for this component not found. You do not have an appropriate license to use this functionality in design mode."
It only gives an option to click OK. When you do it shows a box called "Action Failed" that lists the macro name, condition, action name, and arguments with three button to click on the right of the box: "Step" "Halt" and "Continue". It appears that only the "Halt" button is available to be clicked.
Does this sound like an issue with the Access license or whatever license the macro might have? We're trying to decide if it's possible to restore the functionality of the macro.

How can format proper display for percentage values. What happens is I chose a field as percent, but if I put in 9 meaning 9 % I get 900% as the value is multiplied by 100, but if I put in 0.09 I get 0%.
I just want to put in day 9 and be saved as 9%.

I'm using Access 2002 and need to increase some field sizes, some by increasing the maximum number of characters and others by changing from Text to Memo. When I try to do this I get the message "Microsoft Access cannot change the data type. There isn't enough disk space or memory"
I have two 320GB hard drives and 4GB of RAM and the Access file is a mere 280MB. Can anyone please explain the problem and tell me how to achieve my objective?

I have a DB that was given to me with a SSN field that has the Number Data Type. Therefore, if the SSN has a zero as the first number, it is not coming up. Other than changing data type to Text, is there a property that would keep the initial zero? Thank you for your assistance.

I have inherited a table where the data type is binary in some cases and I want to change these to Numerical. When I do this in design, I get a message which says I can't do that. I have something like 200,000 records.
If I try to export as Text file I get Invalid Argument message coming up. Can anyone help?

I have a table that i need to be able to store text that may be over 255 characters long. I have changed the fields datatype setting to memo as I thought this was able to show Up to 65,535 characters. But the data is still being trimmed to 255 characters. I have looked in Access help at data types and it states that the memo field length is 65,535 characters
"if manipulated through DAO and only text and numbers [not binary data] will be stored in it, then the size of the Memo field is limited by the size of the database."
My question is?
How do I know if it is manipulated by DAO
If it is not manipulated by DAO how can I change it (if possible) as I really need to full data to be retained
I am using Access 2000
Thanks for any advise
