Table Data Type / Look Up?
Mar 5, 2007
Hi,
Trying to get back into Access after some time now and could do with some help please...
I have 2 tables, one table 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 as only a number is shown rather that the text (in the tables).
How can I set it so Mr, Mrs, Miss can be displayed in a drop down list, rather than the Primary Number (ie Auto number).
Make any sense?
TIA

I previously created 2 tables:
One lists all the stock symbols and company names = SYMBOL
The second table lists the purchase information for each stock = PURCHASE
I then created many queries, etc. using this data. Symbol is the key link between the various tables, queries, etc.
NOW that I understand the lookup wizard in the data type, I would like to change the symbol field in the purchase table to a Lookup field. I, of course, receive a message. I am told to delete the relationship with the other tables. If I remove the relationships and change the data type, can I then replace the relationship with out damaging all the queries and forms?

Is it possible to set the yes/no data type fields in an Access table to behave like radio buttons? In other words, if they click yes in one data field, it automatically prevents them from clicking yes in the next data field. If so, how?

My database consists of one large table of approx 3.9m rows and about 12 different columns. One of my columns is of a data type "date/time" but i need the format of this column to be "text"
The problem is that when I right click the table/go to design view/ and try to change the data type, I get the error "Microsoft Access can't change the data type. There isn't enough disk space or memory."
Which means i can't take the easy way out. Is there a way I can just create a new identical table and change the data type of my one column? I was thinking there might be something in SQL I could do, or some how in creating an identical table where only the field type has changed. I should note, I looked up this using the access in file, and it appears the ALTER TABLE SQL will not work on my machine.
the dataset was created from a txt file which as been lost to the ether, and I can't import the database into excel using a macro I didn't write unless the format of my column is text.

I am creating a table that is a master list of all of my company's product. Each "customer" that we have will always be ordering the same items, but not all of the items that we have available. I need a way to go through the master list and click a yes or no and have that item added to the "customer's list of items on a new table.
I need to create a sublist for each "customer" like individual shopping cats for each customer. These individual lists need to link back to the master list in case of product changes, description changes, and cost changes.
I would like to create a form where the end user can type in a product number, description, or manufacturer number and have that item added to the "customer's" list.

I was wondering if there is a way to export the Table Design Structure:
1) Field Name
2) Data Type
3) Description
Into a Spreadsheet.
I was able to do this a long time ago, but can't seem to remember. I'm using Access 2000.
Thanks!
Joe

Is there any work around to this?

I created a table in MS Access using a Lookup & Relationship data-type. This means that my record cells call upon a particular table for values. It creates a LIST of values for that cell.When I query a particular value in this table I get every possible combination of the value. My query and code are below:
OR,
SELECT MainT.Content.Value, MainT.Source, MainT.[Entities Impacted].Value, MainT.Update,
MainT.[Divisions Impacted].Value, MainT.Announced, MainT.Effective, MainT.Stakeholders.Value,
MainT.[Ref#ID], MainT.[Issuing Agencies].Value
FROM MainT
WHERE (((MainT.Content.Value) Like "*" & [Forms]![SearchF]![ContentCB] & "*" Or (MainT.Content.Value) Is Null)
[Code] .....
This means that if I query STATES: "California", I'll get back every possible combination that exists with the name California in that particular field.The issue with this is that I'll get MULTIPLE primary key values rather than just 1. So, if one record, under STATES has California in it, but the other fields in that record have the Lookup & Relationship data-type, then every possible combination of that record will query instead of the multiple field-values form that you'll see in the table I am querying.
notice that my primary key (REF#ID) is repeated numerous times! This obviously causes problems with generating records and forms concerning information for 1 particular primary key. Is there a way around this problem other than specifying search criteria down as much as possible?! Perhaps there is some SQL code.

I'm using MS access and Excel 2000. I have an Excel spreadsheet that contained 8 columns, the first column has all cell format as Number, the rest of the column is set as custom date format of 'dd/mm/yyyy'. When I create a linked table in MS Access, the data types does not matched my excel spreadsheet columns, the 'Number' data type is a double and I want a Long Integer in Access, and the custom date format become text datatype but I wanted a DateTime datatype. Is there any work around this? Seems like it is a common problem.
Your prompt response is greatly appreciated!
Thanks in advance!

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’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.

When exporting a table to excel is there anyway to presever the data structure - ie a text field of length 30 will only take text length 30, Interger would only take integer and date would only take date etc, etc ,etc.

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,
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%.
thanks

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?
