I am trying to change a text field (that has been used to store Dates) into a date/time field so that I can sort it correctly
However, when I try and change the data type, It gets to about 90% on the progress bar then tells me that my system does not have enough memory available, and that an error has occured, data type not changed etc.
My system is fairly powerful, and I don't think that it is strictly the problem.
Any ideas??
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 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?
My database consists of one large table of approx 3.9m rows and about 12 different columns. One of my columns is of a data type "date/time" but i need the format of this column to be "text"
The problem is that when I right click the table/go to design view/ and try to change the data type, I get the error "Microsoft Access can't change the data type. There isn't enough disk space or memory."
Which means i can't take the easy way out. Is there a way I can just create a new identical table and change the data type of my one column? I was thinking there might be something in SQL I could do, or some how in creating an identical table where only the field type has changed. I should note, I looked up this using the access in file, and it appears the ALTER TABLE SQL will not work on my machine.
the dataset was created from a txt file which as been lost to the ether, and I can't import the database into excel using a macro I didn't write unless the format of my column is text.
I am trying to change a field that currently has a data type of number and I want to change it to a date/time data type. When I try to do this, I get a message that says there isn't enough disk space or memory. I am working with a database that has about 100,000 records in it.

Is there any work around to this?
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.
View 7 Replies View RelatedSorry if this is an elementary question, but here goes.
What I want to do is have Access run a query based on the user name "taken from a login screen". That query will return some values such as what team the Supervisor is responsible for, what days off his team has etc...
This information will be used to display all other queries that particular sup runs. When another sup signs in obviously the results will be different
And onto the problem
I have the query running and displaying the result in a datasheet view. I created this to see if the queries work. Now what I would like is to do away with this query (it pops up at startup) and have access save the user name in memory instead of running this query. I also need to figure out how to reference this "user name" piece of data, that will be in memory on the queries.
would appreciate any help you can give on this topic. I have been trying to solve this issue for a loooooong time.
thanks again,
Ricky

i have a temporary table which is created by importing an excel file
some extra fields are then added to the table using sql vb code for example
strSQL = "ALTER TABLE [TBL_TmpSubmission] ADD COLUMN [EnergyUnit] TEXT;"
CurrentProject.Connection.Execute strSQL
these fields are later populated conditionally using an update exectuted again from vb code
If Me.cboProgram.Column(0) < 3 Then
strSQL = "UPDATE TBL_TmpSubmission SET EnergyUnit = 'GWh'"
Else
strSQL = "UPDATE TBL_TmpSubmission SET EnergyUnit = 'CarbonTonne'"
End If
CurrentProject.Connection.Execute strSQL
the problem is that this field now has a memo data type, this is a problem because i need to write a query which uses this field in a table join and access won't let you join on the memo type
anyone know why this might happen? for the time being i'm going to try and fudge this by using a further ddl statement to change the data type back to text but i'd rather know whats going on here
what I want to do is make a button to search range of columns in data table with data type Yes/no and display the results if the value is yes
View 9 Replies View RelatedI have a table and a simple query that pulls results from the table. Nothing too crazy. But, if I were to go in and change some of the data/values in the query results it will change the respective data in the table. I know that this cannot be right. What do I have to do to either prevent the ability to change query results and/or prevent any changes in the query from altering the original data in the table.
View 2 Replies View RelatedI’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.
Pls help.
Thanks.
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?

If I just change the data type back to data, it's going to delete a lot of them.
Is there a way to make the change and preserve my data?
Thanks in advance.
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.
What do I need to do to resolve this? :confused:
Thank you.
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.

Hi,
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%.
thanks

View 2 Replies View RelatedI'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.

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.
View 2 Replies View Relatedi 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
I am using Access 2000
Thanks for any advise
Does anyone know if its possible to change the data type of a field from "Text" to "Number" by using a macro?
