Microsoft Access Can't Change The Data Type
Jan 24, 2007
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.

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?

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?

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 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 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.

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?

In my database i have a field for Tonnage (quantity) ...
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 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...

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???

My main experience is with MySQL and PHP so I'm kindof stumbling around in the dark here. Heres my story:
We recieved a new server and migrating from (Windows Server 2000, IIS 5.0, Access 2000) to (Windows Server 2003, IIS 6.0, Access 2003) has been nothing but problems.
I have setup IIS to work with ASP, I've also setup a system DSN. The access file was copied over from the previous server. We're running Access 2003 and now I can't seem to get this ASP script to work.
When I try to upload a file to the script I get this error:
Line: 42
Char: 7
Error: HELP!!! Error: [Microsoft][ODBC Microsoft Access Driver] Invalid SQL statement expected 'DELETE','INSERT','PROCEDURE','SELECT', OR 'UPDATE'.

I set an alert after this line but it doesn't pop up.
ANY HELP WOULD BE VERY GREATLY APPRECIATED. I'll be checking this very frequently.
Sincerly,

Hello to everybody,
I want to access Oracle 8.0 Data (meaning Oracle tables) with Access 2002. My problem is that I do not want to enter the username and password every time I connect to the Access db, as I want to create some queries in Access which I will export to Excel.
I do not think that this is something difficult but I can't seem to find any solution. Is there any proposal?

Hello everyone,
I would like to convert a database, which was made for me, in order to enable it to be used on my current system.
I get the error message below when trying to open the database in Microsoft Access 2003.
The database was made using Microsoft Access 2.0.
Will I need Microsoft Access 2.0 to update/delete the database all the time?
Or can I convert this to be used with Microsoft Access 2003?
I have tried opening the file exclusively and I get the same error.
I have selected Show Help and it advises me to import all the objects from the database into a new database. This can`t be achieved as I can`t open the file to retrieve the contents.

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?

Hi All,
I was doing a project for school where I had to make a text field that would only accept the options Client Type(RET - Retail, SER - Service, DIN - Dining)
I thought I did it right by having a line with the field name as "Client Type" and the input as "text" with a field size of "3". and the description I put was "Client Type(RET - Retail, SER - Service, DIN - Dining)". But it doesnt work. I saved and everything. It will let me enter anything I want as long as it doesnt exceed 3 chars. I want it to ONLY accept RET, SER, or DIN and I want it to format it so its in CAPS.
Thanks,
-- Steven

Hey all.. I was wondering if anyone would be able to help because I am really stuck with this..
Basically in an Access Database holding messages of online chat conversations I need to run a query to find out which is the longest message and which is the shortest message sent. In order to this the number of characters need to be counted and then the max and min selected however I'm having problems with the data type of the message
Based on the LEN function I first tried :
SELECT User.User, Message.Message
FROM Message INNERJOIN [User] ON Message.[Message ID] = User.[Message ID]
ORDER BY LEN(Message) DESC;
This selected the user and message fields and ordered them based on the length of the message.
In the original Message Table the message field is set to Memo as there are quite long messages the above SQL did incorporate the full messages and ordered them in the correct manner...
HOWEVER.. I need to be able to count the number of characters per message and retrieve the longest message and then retrieve the shortest message.
I tried..
SELECT Message.Message, LEN(Message) AS [No of characters]
FROM Message INNERJOIN [User] ON Message.[Message ID] = User.[Message ID]GROUP BY Message.Message;
This counted the number of characters for each message but it did not incorporate the full messages, the maximum number of characters for the longer messages came up as 255 whereas I know that they are longer than that.. and it only displayed those 255 characters and cut off the rest of the message.
Ultimately I need to select the 'User' from the user table, 'Message' from the message table, Count the number of characters per message and then display the highest but the function needs to be aware of the messages that have characters more than 255 hence the Memo data type setting in the Message Table..
... any ideas/developments on the above??
I have been trying a few different things but getting no-where at the moment.. Ive tried asking in loads of different places but seems I have baffled everyone else as well as myself.
Any help would be greatly appreciated.

I want to create a Web App in Access 2013 that contains a table of client names, addresses etc, and a second table that contains order details, including client name. It would be nice to ensure that as someone adds a new order they are give a drop down menu containing existing client names, and I can see how you can do this for a brand new table using the lookup data type. But I already have an Excel spread sheet containing client names. If I import this into my Access web app to create the client table, and import the existing orders to create the order table, I then try and change the data type of the client name (in the order table) from short text to lookup, it won't let me!! (If I create an empty client table from scratch, it lets me define the company name as a lookup data type - but I can't then import from Excel into this empty table)
