I use Access 2003. I've set the Data Type on a field name to = Percentage
I've tried to use all - Field size types
I want to enter in 50 in the table and have the output be 50% currently it goes to 5000%
Is there anything i have to add in the Validation rule to make it show the exact value?
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?

Does anyone know if its possible to change the data type of a field from "Text" to "Number" by using a macro?
thx
Hi,
I am trying to import an excel spreadsheet into Access2000 using the import wizard.
I choose my XLS file, I say whether or not the first row contains headings, (no is the anwser).
Then I want to change some of the fields to data type of memo from text, but all I can see if Field 1 and data type option is blanked out.
If I click or double click on another field it doesn't change.
so I cannot change the datatype of a field..
do you know why, and how I can fix this ?
The reason I want to do this is one of the rows in excel has 300 characters, and the text field in access only allows 255.
regards,
Jamie
my teacher asked me to do Access homework to change data type from Text to Boolean. Data in "Owned car" field show as Y or N
17178
so I click on Design View and change datatype of this field from "Text" to "Yes/No" , than when I saved it show a message
17179
When I back to Datasheet view, all data in "Owned car" field change to be "No".
How can I change data type to be Boolean type without deleting my original data??? I want them to show the same as Y or N.
I'm a bit of a newbie, so lets just get that out of the way....
I have a field in a table that was originally a text data type. I want to change it to a "lookup" data type using the lookup wizard. However, Access doesn't allow me to do this and prompts me with "You can't change the data type....its part of one or more relationships...". But there are no relationships? There may have been previously, but I've deleted them all from Relationships window.
This has happened several times now. I am in the process of designing the database and have been changing my mind about data types when I realize that I can use a lookup data type. The only fix I have found is to make a copy of the table in question and then change the data type of the problem field. Unfortunately this screws up my forms...which is a pain.
Why would Access say that there are relationships in the relationships window when in fact there are none?
I've attach a copy of my db. The field in question is located in the "Activities" table. The field name is "ACTIVITY_NAME". I am trying to use a lookup from the activityNames table using the "ActivityName" column.
Thanks for any help in this matter.
Hi! I have a problem to build Pivot table in Excel 2003.
I’m creating this table base on the “External Data” which is a MS Access 2003 table.
The table has 50 fields and about 500.000 records. (This is the reason, I can’t just export table to Excel and then do pivoting). One of the fields of this table has a “text” type but stored numbers. Excel does not allowed me do Sum or Max function with this field – it needs to have Number data type.
I receiving this table “from outside”, so I can’t get the right data type from the beginning. If I’m trying simply opening the table, before, using as a data source for Pivot Table, in Design mode and just change data type from text to number, I have an error: "Microsoft Access can't change the data type. There isn't enough disk space or memory."
Any advice, how to change Data type in existing table using queries or something else what can help me to solve this problem.
Thank you very much at advance.
Alec.
Looks like mismatched join types has caused others plenty of headaches in the past!!
I am trying to create a query that connects 2 separate areas of our factory.
The first table (Table 1) has a field called prod_code which is a text field and this code (5 digit number) describes a manufactured product.
The next table (Table 2) also has a field called prod_code which is also a text field, is a different 5 digit number, and describes the same product but after packaging.
There is a 3rd table which I want to use to link both of these tables, but in table 3:
table 1. prod_code = table 3.item_code, and is a long integer. and table 2.prod_code = table3.item_code_prnt, also a long integer.
I need to be able to use table 3 to correlate data from tables 1 and 2.
I suspect I need to use Clng or similar but am unsure how to apply it.
Have been trying to construct an expression but continually get error (bracketing error, join mismatch etc, etc)
Any clues?
I imported a big table from excel with many columns. Access when I brought it in determined that they should be "text" format. I don't want to sit and change each field to a "number-double". Is there a way to quickly change data type for multiple fields at once?

I need for example to input 38.60 or 37.89 so my values must have 2 decimal places, ive searched and found changing my field type to double or decimal should solve the 'numbers rounding up/down' but access will not let me change the data type?
I got Gross Income Query. But I have employees that have overtime rate as well
So I have to calculate using overtime Payment And Gross Income Separately
So I make query and in query . I write this equation
Ovetime Pay: IIf([Total Hours Worked]>[Normal Hours/week],([Total Hours Worked]-[Normal Hours/week])*[Overtime Payrate],"0")
I successfully calculate it ...
BUT IT JUST GIVE ME THE VALUE LIKE A NUMBER SUCH AS e.g. 50 ,150 but instead of that i want currency data type of that calculate field for e.g. 50 become "$ 50".
Okay so in able to do that i go to properties Sheet of the field of the query and change Format to Currency ..BUT IT DOESN'T CHANGE !!!

I have two tables(see below). I want to set up a query, link these 2 tables together. I set a one-to-one relationship between Client ID in two table. But got error message :"Type mismatch in expression".
I tried to change Client ID data type from "Text" to "Number", then Access deleted some data under Client ID in Order table.How can I make this work, but not having to re-type in all data?
Client Table:
Client ID(Autonumber)
Client Name (Text)
Client Address (Text)
Order Table:
Order ID(Autonumber)
Client ID(Short Text)
Unit Order(Number)
Unit Price
So I have decided that I want my ID's to be AutoNumbers, but at the moment they are currently set as Numbers. I have already inserted data, to test, which has been deleted, however I am now unable to change the ID field back to AutoNumber.
How can I duplicate the tables so that this field can be changed again?
I have like 10 tables with heaps of feild, so remaking them will take long, but I know there is a way using queries, I am just not sure how...
I have a table with about 300,000 records. About ten fairly small fields per record. I am trying to change the length of a text field from 25 to 40 characters, and I get the error message, 'MS Access can't change the data type. There isn't enough disk space or memory'.
I have never seen this message before. I have about 64 Gig of free disk space. What can I do?
When I run the analyzer on all object types it recommends to change the data type for field "zip" (zip code) to "long integer to:
"benefit that table and potentially other objects in my database"
The field type is currently set to text, And I have the same setting for the same field in a separate table, yet it does not come up with a recommendation for that table.
Additionally, I don't seem to have the option "long integer" for the field data type???

Hi,
I created a field of type number and formatted to display percentages; however, it seems to add two zeros at the end of every percentage I enter. e.g. if I type 9%, it will show 900%.
Am i doing anything wrong here?
Any help will be very much appreciated.

I have a "make table" query. Inside that query there is a simple expression that divides two fields by one another to arrive at a %. Example 5/100=5%. However, the data returned is not in a % format.I know that I can go into table properties and change the fromat to "percentage", but that will only work for the current table that I have created. Once I re-run the "make table" query, I lose the change to the format, and my value again returns to a number, not a %..
Is there any way to always have a percentage returned without having to manually change the format each time that I run the query, or having to make a "delete" and "append query" ?
On a table I have a field labeled "Interest", and it is for what you would expect.
I have the data type set to Number, and the format set to Percent. For some reason I cannot change this field, it keeps resetting the value back to 0.00% even though I type something else in.

I'm new to this and I've created a report that shows evaluation scores before and after for some training we are delivering. The Query I've created works out the percentage of change for each record. The problem I'm having is that I can't now summarize these percentages for each instructor.
What I'm entering to retrieve the percentage score is:
=(Sum(IIf(IsNumeric([Percentage Change]),[Percentage Change],0)))/(Sum(IIf(IsNumeric([Percentage Change]),1,0)))
What i get back is as follows:
Before score = 2.85 (correct)
After Score = 4.22 (correct)
Percentage of Change = 55% (incorrect this should be 48% )
I'm trying to calculate the percentage change between records/rows. I've searched around the internet and found 2 possible examples, but they are very specific to the individual's database and I'm struggling to understand.
Here are two examples:
[URL] ....
[URL] .....
I believe I need to create a query based on another query (which I can do). I would need to create a column in the new query that calculates the percentage difference, but what's the formula/contents of that column?
I have a table with a field with names set to text data type and i want to change it to number data type but when i do it in design view the data get lost. I want to know if there is a way to convert the data in the field as number type and keep the data in the field.

I have to calculate the percentage of change of the values. I have very basic knowledge. How can I make a query to calculate the percentage of change?
I have a table with the following fields; Row; AnimalID; Weight: Date_Weighed (see attached screenshot example).
I would like to make a query that gives me the percentage weight loss/gain since the last time a particular animal was weighed. For example, animal AAA gained 100% between 2014/01/01 and 2014/02/01. Animal CCC gained 0% between 2014/02/01 and 2014/03/01.
I plan to use this to create a pop-up that informs me if an animal had lost over 15% of its bodyweight since the last time it was weighed, indicating either a loss of body condition, or that a female has given birth.
I have been researching changing the field type of a table to Hyperlink and have been unsuccessful.
Everytime I add a field to a specific table the hyperlinks get busted. What I am doing programmiticaly is:
1. Deleteing the field
2. Re-creating the Field (text)
3. Concantonating two fields into the new field
4. Create a second field (hyperlink)
5. Copy those recrods into the hyperlink field
6. Delete the first
7. Rename the hyerlink to the original feild name
I get this to work but the hyperlinks are still broken.
Programmatically:
If I Create the new field
Concantonate two fields into it
Then Manually Change the field name from Text to Hyperlink
everything works great.
QUESITONS:
WHAT CODE is being run whern you go into the properties of the table and change the field type from Text to Hyperlink?
Can I use that code for this purpose?
Previously, using Windows Professional 2000 and Office Professional 2000, a Access File > Export... would always assume (default to) Excel (.xls) as the "Save type As...".
Now, my system has been upgraded to XP Professional and Office Prof 2003, and now the File > Export... always defaults to Access (*.mdb,...) as the file type. It is not a big problem, just a nuisance. I don't like repeatedly re-selecting *.xls from the drop down list every time I export. (After all, computers and even upgrades should make our life easier, not harder, right?)
Can I somehow select or configure Access to use *.xls as the default Export... file type?
