hi there
how many columns is the maximum in a query?, because i have one that has 26 columns , but i need some more... what can i do?? is there a way to add some empty columns to a query??
thanks
I need to know about "Need to query result from access2007 find only "one maximum number" in hour per day every cell ID"
How I use sql command?
See my file at ...
I would like to know if there is a maximum nb of columns to use in a table or at least a prefered max nb. For example i have a table "customers" and inside i have "name" "last name" "age" "gender"..and so on is there a limit?
By the way i'm using access 2007
Thx for the explanation in advance.
Hi,
I'm trying to get the maximum number in a table field to increase it by one depending on the member that is selected in a drop down in a field.
I have three tables: members, programs and times. Each member can have N programs and each program can be broadcast N times.
Each member has a three digit code, like XXX. Each program has the three digit code of the member + three numbers that are supposed to auto increment. That is, the first program of member X with the member code XXX is called XXX001.
What I'm trying to do is that when a new program is filled in and I select the member, then the program code should update automatically, adding one to the latest program by that member.
That is, if the last program by member X that was inserted in the database is XXX010, then if a new program is inserted it should automatically be XXX011, even though programs by other members have been added in between.
This is the code I use now, for the AfterUpdate when selecting the member in a dropdown in the form. But although I've played around a bit, I just get error messages...
Private Sub medlemsruta_AfterUpdate()
Dim medlemskod
medlemskod = Me![medlemsruta].Column(2)
Dim strMax As String
strMax = DMax("programs_kod", "table_programs", "Left$(programs_kod, 3) = medlemskod")
Me!program_kod = Left$(strMax, 3) & Format$(Val(Right$(strMax, 3)) + 1, "000")
End Sub
Medlemsruta is a dropdown where one selects the member from the members table, where the three digit code is in the third column (Column(2)).
I'm trying to use DMax to get the maximum number for the particular member and after that adding 1 to that for the new program code.
Grateful for any advice! Thanks!
Hi,
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.
hi all,
This is general question only. How many number of records that Access can handle as a maximum records?
Or it only depend on size limit (4GB)???
thanks
My 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.
I have created a db for my warehouse, now what I want is to set a maximum no of items to be issued to one person = 20 (means 20 rows only) in a subform. If the number exceeds it prompt user that you reached to the maximum no of issues.
View 2 Replies View RelatedI have run into a problem with an ODBC table connection. The table I am connected to exceeds the number of fields allowed in an Access table. I am using Access 2003. When I looked on Microsoft help site I think the max number of fields in a recordset is 242 so I am unable to see all of the fields in the original table I am linking to. Does anyone know if this limitation has changed in the newest version of Access? I checked the Filemaker www site and that program does not have the same limitations. Thanks in advance for any help!

Is it better to have many fields in one table or to split the data between a number of tables and link them?
Thanks.

I have an Access database with a table that contains 11 fields. The first is a unique ID and the other 10 fields are various numbers. I need to know which of the 10 columns contains the highest number for each row and return the 2 rightmost characters of that column name. I started with the "maximum" function that I found on-line and it works to give me the maximum number in each row, but I need it modified to return the 2 rightmost characters of the column name that contains that number.
Code:
Function Maximum(ParamArray FieldArray() As Variant)
' Declare the two local variables.
Dim I As Integer
Dim currentVal As Variant
' Set the variable currentVal equal to the array of values.
[Code] ....

Can someone help me out on this:
I have a table 'articles'
ID --- date --- authorID
1 --- 20060901 --- 1
2 --- 20060902 --- 1
3 --- 20060903 --- 3
4 --- 20060904 --- 3
5 --- 20060905 --- 2
I need a query that will produce the records that have maximum date for each author (distinct authors), ordered by date descending.
For example, output should be in this case:
5 --- 20060905 --- 2
4 --- 20060904 --- 3
2 --- 20060902 --- 1
Hope that you understand what I mean...
Please help!
I know that tables have a max of 255 fields. How many can you add to a query?
I have a large database that is divided into several tables. When building the query to select all the data I will be way over 255.
Will this be an issue?
Thx!
I was able to use the UNION ALL qry. But, when I have another file (like original2) that does NOT have all the columns listed in the UNION ALL qry, I get a Parameter value box asking for the missing columns when I run the qry.
Example:
original1IDDateGroupChristianJohnnySteve 18/5/2013A1528/5/2013B338/5/2013C2348/5/2013D2358/5/2013E5
original 2IDDateGroupChristianJohnny18/6/2013A212528/6/2013B2338/6/2013C2248/6/2013D22
The UNION ALL qry includes all the possible resources ( includes all the possible column fields Christan, Johnny, and Steve).
When I run the UNION ALL qry with the original2 file, An "Enter Parameter Value" box is displayed with the mssing column name "Steve".
Is there a way to Map the original2 table into a working table with all the columns, or use VBA code to construct the UNION ALL qry to only include the existing columns? My data has variable columns and I'm trying to avoid the parameter popups.
Is it possible to increase the number of columns in Access 10?I upgraded MS Office because I knew Excel no longer restricted you to 256 columns. I often pull data from a data base that uses as many as 800 columns.When I try to open these files I get a "too many cross tabs" error prompt.

I have a small database which lists delegates for courses.
I have a venue which will hold only a small amount of people
is there a way of stopping data entry when it gets to a certain point. ie putting a limit on how many columns can be entered on a single table
Is there a way to change the formatting of a numbers column to the formatting :
1 = 0001
11 = 0011
111 = 0111
1111 = 1111
But that would have to apply to this also
1 - 2 = 0001 - 0002
11 - 22 = 0011 - 0022
111 - 222 = 0111 - 0222
1111 - 2222 = 1111 - 2222
If that makes sense ....
I have a table in a database with 7 columns. The data is sorted by Date1 in descending order.
For each pid I want to put the sequence numbers
First record has two conditions
If string 2 is null then start numbering from sequence1
If string 2 is not null then start numbering from sequence2
If string 2 = string1 then
Sequence1 = 0
Second record has two conditions
Number sequence2 with the value 2 or 3 depending on the line one
If string 2 = string1 then
Sequence1 = 0
Else
Sequence1 = next number
Same condition for the rest of records
I have a report that constists of 4 subreports.I need the first two subreports to render in a two-column format and the 3. and 4. in a single column format.Unfortunatelly I cannot it work as I need to.I have read, that setting the main report in a single-column format and the subreports in a two-column format with "first across then down" setting (Or something like that) is and option.
Unfortunately this option does not fit my requirements.Is there a possibility to set the number of columns through VBA and change it across the different parts of the report?
I am working with a large database of 8,000+ entries. We have five tables in this database, but mainly use three of them. The main table is "OAKE Main Table" which is basically a list of all members our organization has had. Each member has accounting data linked to their member ID number which has been generated by ACCESS, and can be accessed or edited by clicking on a sub table next to each member. The accounting data that has been manually entered in the OAKE Main Table can be found in the Accounting table.
Here's my issue. I need to be able to extract a list of transactions from this accounting table since January 1st. I can do this no problem, but all I get is the member ID and the accounting data. How do I get ACCESS to include the member ID's first and last name? or maybe even the first, last name, address, city, state, zip, etc so that I can get a list of people who have made donations, for example?
I'm assuming this will have something to do with the relationships we have set up in our table. Here's a picture of it. I have no clue how to make this work.
