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 need to create a user interface that will allow a boolean type search of a field. This would mean item1 AND item2 AND NOT item 3, item1 or item2, item 1 NOT item2, etc.
I've set up a combo box setup with the following script, but I can't figure out how to adjust it to allow the multiples.
Please advise if I should adjust this or try a differenmt interface format for my users.

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.
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.
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.
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?
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???
I would like to change the text formatting (color, italics, bold etc) of the contents of a control based on a boolean value in the underlying datasource of the report.
For instance, I have a report that generates a "Proforma Invoice" i would like to ability italicize the prices of certain items based based on a boolean value (EstimatedPrice) in the underlying datasource.
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 a form used to gather data around some supplier details, and we have a review check box with Boolean data. I'm trying to establish a filter button to filter un-checked boxes by specific suppliers from a drop-down list.
Although I've been able to run filters on suppliers and the review checks separately, together I get a "Type Mismatch" error. I thought it might be because of the Boolean data type, so I tried converting that to String but get the same issue.
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?
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?
I have an existing form where users type in information and it generates a couple of reports. In one of the fields, Customer PO Number, the user enters a number from a customer. Up until yesterday all of the customers we have been dealing with have used numbers only for their PO numbers. However, we have a new customer that requires alphanumeric PO's. Is there a simple way to change this field from a number to alphanumeric without having to redo each form, report and/or query. I am using MS Access 2010.
I am trying to change the button color on a subform if a related form data changes.Main form is products with a continuous subform with serial numbers of products i.e, serial number, location, price and a button to add addtional issues if there are any for this particular serial number (this will open up another form related to the serial number so I can add an issues if there are any).The reason I would like the button to be a different color is so I can quickly see if there are any additional notes been added to the serial number. Just in case you may ask why not add the field to the continuos form is that the issues and be quite lengthy and there may be lots of serial numbers on the form
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?
