Replace Chars
Feb 14, 2006Hey guys,
having a problem with a query, its used to export data to a txt file for another program.
the problem is i have a field that i format with end of line chars between entries in the field, so in access it looks like a few entries rather than one field (there were reasons for this).
when it comes to export this data, i need to remove the end of line chars with spaces.
heres the part of the query i need to fix:
Description: IIf(InStr([Order_data].[Stock2],Chr(13)),Replace([Order_data].[Stock2],Chr(13),Chr(32)) & Replace([Order_data].[Stock2],Chr(10),Chr(32)),[Order_data].[Stock2] & " " & IIf(nz([Order_data].[Stock3])<>"",IIf(InStr([Order_data].[Stock3],Chr(13)),Replace([Order_data].[Stock3],Chr(13),Chr(32)) & Replace([Order_data].[Stock3],Chr(10),Chr(32)),[Order_data].[stock3]),""))
yes that is nasty.. but simple to understand. 2 fields get combined for output (stock2 and stock3), i check first if they need to have chars replaced, then replace if necessary. the output i get though doesnt seem to be replacing the chars, it finds them there with the if however.
any help?
thanks guys
String Of Chars, And Validation Rules
Sep 16, 2007hi there,
im working on a project for the boss but i've come across a couple of problems
first, i'd like to know if there is a way i could search for a specific string of characters inside a field, for example, search for a 'malouf' in the name field (without having to reclassify my fields separately as first name and last name). i've tried the LIKE command, but it doesnt work the way i'd like it to.
And other question, i would like to create a validation rule for a field in an entity, but it is based on whether or not a record was in a query result. specifically, my validation rule is that i cannot put in a particular TruckName in the Truck entity if in my query "Unavailable trucks", that particular TruckName is listed there. Ive tried so many IIF commands but i dont really know what to do.
thanks a lot guys!
General :: Can Count Down Remaining Chars Of 255?
May 11, 2013TextBox1 has, of course, a maximum of 255 Chars.
I imagine Unbound TextBox2 will count down from 255 with each keystroke entered to TextBox1 so I know when my limit is getting close.
Access Auto-correcting Strange Chars
Jun 19, 2007Is there a way to prevent Access from "auto-correcting" certain characters?
Example: If I enter "DEJA VU" into a table Access changes it to "DÉJÀ VU" with the strange É and À characters. I don't want this to happen.
There must be a way around it.
Thanks for your help.

How To Select The Maximum Value
Jul 17, 2007Hi all
I have an expression in a query which is checking a list box on a form. If the list box is empty (is null), then I would like the query to search on the highest (maximum) value in the specified field (CourseFK), otherwise it will look for the value in the list box.
Expr1: IIf([Forms]![frmEditDeleteStudentDetails]![lstEditCourseFK] Is Null,[CourseFK]=Max([CourseFK]),[CourseFK]=[Forms]![frmEditDeleteStudentDetails]![lstEditCourseFK])
However it seems Access will not allow me to do this - I get an error about an aggregate function in a where clause.
Can someone please suggest to me how to get around this? Eg, is there an alternative way to search for the maximum (still needs to be determined dependant on the list box).
Thanks

Maximum Value Across Fields
Jul 12, 2007I am a beginner and have a very basic query. I would like to create a field which returns the maximum value across a number of fields for each record. Is there a function that would do this?
To explain in more detail, each record is a customer and the fields are their purchases by month. I would like to get the maximum monthly purchase amount for each customer over the past year.
Maximum Number Of Connections
May 4, 2005Hi,
we use access for localisation in our application. The business object which accessess the access uses DAO connectivity and we often land to
"Too many client tasks" problem.
is it wise to change the DAO to ADO? if so the above problem will go off?
what are the chances that the problem still persists?
is that access has any limits on the number of connections? like 64, 255? or is that ADO/DAO has any limitaions on the number of concurrent connections to access DB?
Pls help, your help will be highly appreciated.
Thanks,
Venkat.
Maximum Amount Of Users
Sep 26, 2005How many users can an access database support? I'm setting up an app accross 3 workstations but each has multiple users. There may be as many as 1000 records a day entered. Can an access database handle this or do I need to switch to sql server?

Maximum # Of Fields For A Table?
Aug 17, 2007I understand that the maximum file size for an Access db is 2GB but can you essentially have as many fields as you like as long as you do not exceed the 2GB threshold?
I am doing some planning for creating a database with ~90 fields and want to know before I start it whether it will be able to handle that many.
Maximum Number Of Relationships?
Jun 3, 2005My issue:
Does anyone know the maximum number of (one to one) relationships with cascading deletes a table can have?
Background:
I have a split database peer-to-peer application with ten simultaneous users, 250+ linked tables running on A2K, AXP and A03. MSDE and SQL Server are presently not viable options.
I'm unable to manually or programmatically relate one table to 73 others with referential cascade deletes; some of the 73 are related to still other tables. The one table is used as a recordsource on a subform on each of 73 different main forms, each of the latter having a different recordsource.
In other words, I want to delete a record in any of 73 different main forms, each with a unique table recordsource, and then cascade delete a subform record (which has the same table recordsource, regardless of the main form).
If I combined the 73 into a single table, I'd have a monster record with 500+ fields, assuming the latter is even possible, and in which event perfomance would suffer from excessive network traffic.
What I've tried:
I haven't worked this issue for some time and have forgotten the number of relationships for a single table I've been able to create. As I recall, it's on the order of 20 relationships maximum for one table.
Of course, I can do it programmatically delete the subform record on the OnDelete event of the main form, but, for elegance, I'd like to use a cascade delete.
Peer-to-peer network performance is not presently a problem.
Maximum Nb Of Columns In A Table

By the way i'm using access 2007
Thx for the explanation in advance.
Need To Return Only The Maximum Record
Sep 20, 2005My quiery is supposed to search through a table of names, and find the latest timesheet entry date for each name, as follows:
ID: 1
Name: John
Timesheetdate: 1/1/2005
ID is specific to each name.
I want the result to be a single row for each ID/name, and to return ONLY the latest timesheetdate (this could either be the maximum value or the latest entry).
I have a feeling that this is a simple problem, but i just dont have the knowledge to do it, any help would be greatly appreciated!

Returning Maximum Value For Max Date
Dec 14, 2005I need to create a query that will return for the latest document, the greatest document number. If I do select max(doc_date), max(doc_nbr), I end up getting the max doc_nbr, but it has an earlier doc date. How would I structure the query to do this?
An example is for these values:
1/30 1
1/30 3
1/30 5
2/28 2
2/28 4
The result should be:
2/28 4
I will then need to see if this returned value is different than the value that was returned the day before, but I am pretty sure I know how to do that.
Thanks,
David

Is There A Maximum Size Of A Recordset?
Feb 4, 2006Hi!
I have a database with a lot of chemical data. My ASP page allows the user to search out all data from a specific location during a specific time period. It then creates a normal html table with the results.
The problem is when I have a large time period and a lot of parameters. For example: data from location 1, 1959 to 2005 returns a HTTP 500 error. When using "on error resume" only the code and data from the last three years are printed (all html tags etc missing from the beginning of the page).
When I choose the period 1959-2002 it works, and also if I use 1970-2005 (which shows that it's not corrupt data in the 2003 year).
My question is: is there a size limit for a recordset? If so, how do I solve this? If not, what could be my problem? Size limit of html pages?
Thanks
Martin
