I want a column in the query to be used for sorting but it depends on the type of data. In preparing to use my tables, I used a simple conditional formula:
Given that the test condition discovered that the data is numeric, the result is the data typed as double. Yet the result is left-justified, showing that the datatype is NOT numeric.
Then when I do it explicitly:
good: CDbl("123")
I do get a right-justified numeric field.
Why doesn't IIF() return the value as a numeric 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.
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.
I want to input data number such as 0.5 in my table, but it doesn't work. I already fill field size : integer with format : Standard with Decimal : 2, but the result is always 0.00 not 0.50 as my expectation. How to define that in my table?
I have specific query related to Access, Currently I'm trying to create all possible combination of lot data. I need to know if this would be possible in MS Access.Below is simple example of what is required
I have 3 sets of data for which I've to create all the possible combinations but with restrictions.Below are few of my restrictions
1. "Value2" always comes with "GateC" & Vice versa but, both don't exist independently. 2. "Value4" always takes "TokenW", But "TokenW" exists independtly as well doesn't need Value4 always.
user_change primary key = user_change_id (AutoNumber) user_id (Number) which relates to the user_id from "users" table change_type (Text) action_date (Date/Time) ...
In user_change I record any changes made to the users table.
What I am wanting to do, within a query, is pull basic details from the "users" table (forename, surname, etc.) which is working fine, but also add in SPECIFIC data from the user_change table if it exists.
I want to pull ALL rows from the users table, not just specific rows, and not just rows where my criteria for the user_change table match.
This is the data I want to pull from user_change...
The MOST RECENT action_date WHERE change_type is LIKE "*issued*".
However there won't be a change_type LIKE "*issued*" for everyone - I want it to be included only if it exists.
At the moment my query is ignoring any users who don't have a user_change record with "*issued*" in the change_type value. I'm also getting duplicate user rows where people have more than one value for "*issued*" - I only want the most recent one...
I understand the IIF(), but what's happening with the crazy characters? (It works the text changes from yellow to green). I tried replacing it with conditional formatting on the actual data control. That only changes color when I click on the control. The above shows the color all the time.
I am exporting data from the database to an excel sheet. Then I want to apply conditional formatting to the data so values between a certain range should be a certain colour.
But nothing happens when applying the conditional format, or when just trying to fill a cell in excel. Only when repeatedly clicking fill cell in excel does the colour change. Also all the cells are in the number format.
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.
Hi, Trying to get back into Access after a long time, just need some refreshing :) tips.
I have 2 tables, one of the tables 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 on my form as only a number is shown rather that the text.
I have a rich text editor that I want to use to post HTML to an access database field. The average post will probably be four hundred or more characters. What is the best Data Type to use for this. I am looking at going with Memo but I want to be sure.
In my Access forms, i display data by month wise; and i want to give the conditional formatting with two condition;
If date of today is greater than target date for that month and if got value more than 0 - Red color If date of today is lesser than target date for that month and if got value more than 0 - green color
Target date for every month in available in a separate table.
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%.
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'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 a DB that was given to me with a SSN field that has the Number Data Type. Therefore, if the SSN has a zero as the first number, it is not coming up. Other than changing data type to Text, is there a property that would keep the initial zero? Thank you for your assistance.
I have inherited a table where the data type is binary in some cases and I want to change these to Numerical. When I do this in design, I get a message which says I can't do that. I have something like 200,000 records.
If I try to export as Text file I get Invalid Argument message coming up. Can anyone help?
i am creating a database that will include four (4) tables that need to have an autonumber as a primary key, but i need that autonumber to be preceded by a letter (one letter for each table). i am creating forms for the users to based on these tables for users to enter data. please help...i'm running short on time. thanx!
the database i'm creating will be used to store city issued permits. there a 4 different types of permits that can be issued, some w/the same info (i.e. contractor, owner) and others with different data (certain permits are only issued for a specific # of days, others require a tap or meter size, etc.). i have separate tables for the contractors, owenrs, and payments, but each payment needs to be associated with a particular permit #. for example: check #3 from john doe contracting is associated with permit # m123, or h123, etc. that's why i decided to have a separate table for each permit type. i was attempting to avoid data redundancy. i also need separate forms for the users to enter data into as per their request. i'm open to suggestion if you have some other ideas. thanx in advance. :confused:
I have a table that i need to be able to store text that may be over 255 characters long. I have changed the fields datatype setting to memo as I thought this was able to show Up to 65,535 characters. But the data is still being trimmed to 255 characters. I have looked in Access help at data types and it states that the memo field length is 65,535 characters
"if manipulated through DAO and only text and numbers [not binary data] will be stored in it, then the size of the Memo field is limited by the size of the database."
My question is?
How do I know if it is manipulated by DAO
If it is not manipulated by DAO how can I change it (if possible) as I really need to full data to be retained
