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 Replieshi 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
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.
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 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] ....

View 2 Replies View RelatedHi People,
I am working on a database related application in which the user enters the data from the form and it is stored in 3 related tables in DB.
This is what I want to do,
If IsNull(Me.Q1_2005) = True Or Me.Q1_2005 = "" Then
rs!January2005 = Me.Jan_05
rs!February2005 = Me.Feb_05
rs!March2005 = Me.Mar_05
If parametername = "time" then
rs!Q12005 = DMax([Me.Jan_05], [Me.Feb_05], [Me.Mar-05])
else
rs!Q12005 = DMin([Me.Jan_05], [Me.Feb_05], [Me.Mar-05])
End If
If user enters monthly data of Jan'05, Feb'05 and Mar'05, but he is not entering quarterly data of 2005 Q1. So I need to update Q1 data in that record, that has a condition. If the parameter name is time then I want maximum of the three month data assigned to Q1 record in DB table else I want minimum of those three text box values assigned to Q1 record in DB table.
Please help me with this kind of conditional statement.

hi all,
I've got one question regarding dates.
I've already make the form to show the count of records by using query according to the start and end date selected by the user.
What I want is when I open the form, it should show the results of count between the minimum and maximum dates inside the data table. It means I want to show the count result without date specification that is the total count from all records of the whole table .
Can anyone help me how can I make it?
thanks a lot in advance.
I have a form [IUDATA]
I have a add record button.
I have a date field [DATEIN]
I have a text field [DRPNO]
If the [DPRNO] field is empty, I would like the user to have the [DPRNO] field be automatically populated after the user enters a date.
I'd like the format of [DPRNO] to be "dpr YY-XXX"
Where:
YY is the year of the [DATEIN] field and
XXX is number of records in that year.
So for example, if it was the 4th record with a 2013 date the [DPRNO] would be dpr 13-004.
I've created a report and report has the same number of pages as the number of records that it's displaying.
If there are two records, the report has 4 pages...the first 2 are the actual report and then the other 2 are a copy. If there are 3 records, the report would have 3 copies (...6 pages).
Any idea how to change this so that I have only one copy of the report?
One shows my form with the Transporters Subform with 3 entries, and 1 entry.The three line items that say "Transporter" are in one subform. I used this code
Code:
Private Sub Form_Current()
If Me.RecordsetClone.RecordCount >= 3 Then
Me.AllowAdditions = False
End If
End Sub
to limit the number of records I can add to 3 or less.My issue is that I lost the blank text box that allows you to add another record. So, if I only have one Transporter listed, there's no box to let me add a second or third.I have the following properties for the Transporters Subform set to "Yes":
Data Entry
Allow Additions
Allow Deletions
Allow Edits
Allow Filters
Here is my issue. In a table with an Auto Number index some records have been deleted. I have been able to recreate them along with their original auto number. The problem is that I do not know how to append these records forcing the original auto number. I have tried changing the auto number field to a number field in the table, this works except I cannot change it back to auto number.
I am sure I’m not the first with this question or issue. I did search through a couple hundred entries about auto number before I posted this question.

I have a Table where the are several entries all with Fields A, B and C
the same, and varying values for Field D.
There are several different values of A, B and C.
I want have a query, pick out each combination of A, B and C and just the
Max value of D for that combination.
It looks as if it should be simple but I can't figure out how to do it?
Anybody able to help?

Hi 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
Hi,

How do you find the maximum of four fields in each record of a query. Say (for example) you have daily records of the rainfall across four cities, where the cities are the fields in the query. how do you write an extra calculated field to the query that shows the max. rainfall across the fields on a paticular day.
Many thanks if you can help

I 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.
How 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?
