Attempting To Change Data Type For Field But Can't Because....
Dec 20, 2006
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.
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 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?
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?
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.
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.
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?
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 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.
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 am a newbie here so i dont know all the cool names and phrases for everything so be gentle with me :).
My boss wants me to make it so the address of a company automatically pops up in the database, so if they call multiple times, the user doesnt have to keep putting the address in. If the company hasnt called before, the user would have to fill out a company form that pops up if the companys name isnt already in the database. Any info on how to do this would be EXTREMELY helpful.
I also need to know how to make access send you an email if certain information hasn't been finalized after a certain period of time.
Thanks for your help guys. Ive been stuck on these problems for A WHILE to say the least...
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?
From a table I want a text field which has a path to a file to be copied automatically into a another field of the same table with a hyperlink text type...
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.
hello people, i wanted to add a string at the end of a long column of Currency. Is there any to to change only the last field to a string or do i have to change the whole column just for the last field?
I have a query to go through a table and pick up the amount of money earnt during a period then I use that field to calculate commission, but the commission field just shows up as numbers and not as currency as the set field in the table does. Is there anyway in SQL to say what sort of data type a field should be... Example of sql string
SELECT Sum([Work].[Earnings]) AS [Period Earnings], [Period Earnings]*(17.5/100) AS [Commisssion] FROM Policy
Access 2002/2003. I have inherited an old Access 2000 database where one of the fields in the table had a Number data type with TEXT in it. I noticed the wrong data type and I change it to text. All appeared OK until I attached a combo box to this field. When clicking in or opening the combo box in any row in this table with the old text, I get an error message: "The value you entered isn't valid for this field. For example, you may have entered text in a numeric field or a number that is larger than the FieldSize setting permits." This field has about 3,000 records in it, and it appears to be corrupted and a permanent numeric field, I have tried everything to fix it: Compact and Repair; Import, append, and update this field into another table/field and I cannot get rid of the error message. How do I get that Number field finally and completely converted into a TEXT field? Anyone got any ideas? Thank-You! :o
I have a question about an Access form that I am creating. I have a "Due Notes" field, which has Memo data type and I create a form "Estimates" using a text box with the control source is that "Due Notes" field to enter notes when needed.
Although I have the vertical scroll bar for that text box (due to other controls, I can not size the text box too big), does anybody know how to display that text box in form "Estimates" with the data of the last text within the size of the box without scrolling down so I can start typing for the next entry? Do I make sense to you?
Please help and let me know if you know HOW. Thanks so much in advance.
