Greatest Values Question
Sep 27, 2007
Hi everyone
This seems like a really simple problem, but I can't figure it out...
-I have a table that contains machine problems, and their duration times
-I made a query that filters the problems based on the date of occurance, and adds up the duration times for a specified problem for the date range
Question: How do I get it to display the top 5 (i.e. 5 with the longest duration) problems? Can the max function work for more than one record?
:confused:

Situation:
When logging into my network I record several key information about every computer. The only two fields that concern me at the moment are Username and Computername. I am trying to retrieve the user of each machine. My problem is sometimes users will log into machines that are not theirs. This situation can make my queries somewhat inacurate as I will explain below.
Sample data:
Username Computername
JSmith Comp1
TJones Comp2
TJones Comp1
JSmith Comp1
Perfect World:
What I would like is to individualise this information to the specific party in one complete sql statement. So that I can run the statment with each machine as the variable and allow it to pull the appropriate information for the user.
Example:
JSmith uses comp1
Tjones uses comp2
What I have tried so far:
Max() this seems to treat them as alphabetic characters and returns the user with the highest alpha/numeric value that has logged onto the computer.
Min() see Max()
Last() this seems to be the most accurate option I have, because it should be correct 90% of the time. Though it still has its inherent flaws as the primary user does not have to be the last user necessarily.
I have tried to look for information in both my help file and this website, if someone would please point me in a direction I would greatly appreciate it. Thank you.

I have a table that keeps track of how many times an account is listed. I want to write a query that will only return the greatest number of occurences for that account. For example if acct 12345 has 3 occurences in the database I only want to return the information that is associated with the #3 occurence. As stated there is a field that calculates the number of occurences for each account so in this case there would be a record for 1, 2, and 3 occurence so I only want to see #3. Hope that makes sense. Thanks!

I'm using Access 2010. I need to calculate a score based on values selected in a table by looking up corresponding values in other tables. I have a "Project" form to create new entries into the Project table (see Table 1). When I create a new project record, I will select values for the Payback and Need fields by selecting options from a list. The Payback list is pointed at Table 2 and the Need list is pointed at Table 3. In the below example, I created the "ABC" project and selected "1 year" for the Payback field and "Repair" for the Need field. Pretty simple.
Now that I have the "ABC" project loaded to my Project table, I'd like to create a report that will show a "score" for this project. The score should be calculated as follows: Payback Impact + Need Impact. In this example, the score should be 30 (Payback Impact of 20 + Need Impact of 10).

I have the following dataset in a table called NR_PVO_120. How do i pick out a number (which can change but let's say, 6) of UNIQUE OtherIDs without excluding any OtherIDs under any fax numbers?
So, if you pick OtherID from Row7 you then also must pick OtherIDs from rows 8 and 9 because they have the same fax number. Basically, once you pick an OtherID you're then obligated to pick all OtherIDs that have the same fax number as the one you picked.
If the number requested (6 for this example) isn't possible then "the closest number possible but not exceeding" would be the rule.
For example, if you take OtherIDs from rows 1-10 you will get 6 unique OtherIDs but row 10 shares a fax with rows 11 and 12. You either need to take all 3 (but that will raise the unique count to 8, which isn't acceptable) or skip this OtherID and find one with a fax that has no other OtherIDs and that isn't on the result set already. My result of 6 UNIQUE OtherIDs will need to contain ALL OtherIDs under any fax the existing OtherIDs are connected to.
So one solution is to take rows 1-6, 26. Another is to take rows 1-4,10-14.
There will be many possibilities (the real dataset has tens of thousands of rows and the number of people requested will be around 10K), as long all OtherIDs connected to all faxes on the result set are part of the requested number (6 in this case) any combination would do.
A few notes.
1.Getting as close as possible to the requested number is a requirement.
2.Some OtherIDs will have a blank fax, they should only be included as a last resort (not enough OtherIDs for the requested number).
my table (NR_PVO_120)
Row OtherID Fax
1 11098554 2063504752
2 56200936 2080906666
3 11098554 7182160901
4 25138850 7182160901
5 56148974 7182232046
6 56530104 7182234134
[code]....
A few sample outputs
one solution is taking rows 1-6 and 26.
OtherID
11098554
56200936
25138850
56148974
56530104
56148975
Another solution is taking rows 1-4 and 10-14.
OtherID
11098554
56200936
25138850
56024315
56115247
56148974
This is for a fax campaign, we need to make sure no fax number is faxed twice, that all people connected to that fax number are contacted under one fax sent.

In Access 2010 I have a Data Entry Form on which I have an unbound textbox in the header that the user can put a default date in. In the body of the form is a bound textbox that records the date and the default value is set as =defaultdatestat (obviously the name of the box in the header).
Problem: The default date shows up perfectly until a value is put in any of the other text boxes.
For further info : If you put values in text boxes default value disappears; if you then push escape the default value reappears when the values in the text boxes disappear.

I have a query with an INNER JOIN and ORDER BY that is working great. Now, using the same JOIN, I need to update values in one table with the values in another. I thought it would be simple until I learned you can't do an ORDER BY with an UPDATE. Is there another way to achieve the same result? If you remove the 'ORDER BY', the statement below doesn't produce an error but the results are not correct:
UPDATE TableA INNER JOIN TableB ON (Left(TableA.CDN,6))=(TableB.CDN)
SET TableA.HCC = TableB.HCC
WHERE TableB.HCC Like '241*' AND TableB.BBB = 'X' AND TableA.CCC = "1234" AND TableA.HCC IS NOT NULL
ORDER BY TableB.HCC, TableA.CDN;

I have several result fields which are all drop down lists. I want each result field's drop down list values to be different depending on the selected value of the Test1 drop down list.I came up with using the .rowsource keyword. My syntax seems to be fine but I'm not getting any values under the result fields when I run the form.Here is my code so far:
Private Sub Test1_AfterUpdate()
If Me.Test1 = "Stress Echo" Or Me.Test1 = "Stress SPECT" Or Me.Test1 = "Stress PET" Or Me.Test1 = "Stress MRI" Then
Me.Test1Result2.RowSourceType = "Value List"
Me.Test1Result3.RowSourceType = "Value List"
[code]...

I'd like to create a query which will consist of simple SELECT statements as follows:
SELECT [table1].[field1], [table2].[field1], [table2].[field2]
FROM table1 INNER JOIN table2 ON ([table1].[fieldX] = [table2].[fieldX]);
The challenge arises b/c instead of joining on equal values, such as the following:
[table1] INNER JOIN [table2] ON [table1].[field1] = [table2].[field1]
I would like to join based on equivalencies, such as:
[table1] INNER JOIN [table2] ON [table1].[field1] = 34 is equivalent to [table2].[field1] = 2;
I do not know the proper syntax, so this is where I need help. I tried to search online without any success.
I appreciate your help in advance.

I'm trying to determine the SQL to return only those records in a table which have duplicate values in each of two fields, but different values in a third field. Here's an example:
Code:
AcctNum FoodType FoodClass
------- -------- ---------
A123 Apple Fruit
A123 Apple Fruit
A123 Grape Fruit
A456 Potato Vegetable
A456 Potato Perishable
A789 Carrot Vegetable
A001 Banana Fruit
For the above table, I'm trying to return records which have multiple entries for AcctNum + FoodType, but DIFFERENT values for FoodClass. So for the above table, the query would return:
Code:
AcctNum FoodType FoodClass
------- -------- ---------
A456 Potato Vegetable
A456 Potato Perishable
It returns these two records because there is more than one record with for the AcctNum + FoodType (i.e. 'A456' + 'Potato'), but DIFFERENT values for FoodClass (i.e. one record has 'Vegetable' while the other has 'Perishable').

I have two tables.descriptions I'd like to relate and use to find/replace in bulk.
[Checking].[Description] (with the source data)

I'd like the values in [Checking].[Description] to be replaced with the values in [Rename].[NewDescription], including those that are "Like".
Examples:
[Checking].[Description] = Geico 12345
[Rename].[NewDescription] = Geico
[Checking].[Description] = Geic
[Rename].[NewDescription] = Geico

I have a travel time database that should tally the number of minutes traveled and convert them into a time (hours and minutes). I, however, am having difficulty converting the numeric values cleanly. Is there anyway to convert 102 minutes + 100 minutes + 110 minutes = 312 minutes to 5 hours and 12 minutes cleanly? I need to take averages of time traveled and hours worked but cannot do this correctly. Thank you for any help in advance.:eek:

There is a text box in a form that user can enter the value.
How can I check if the value entered by user is already existed in the record of the linked table or not?
If the value (or record) do not exist, that new value/record will be added to
the table.
If the value do exist, just show the msgbox to indicate.
How can I do that ? :confused:
Thanks

Firstly, is it possible to hide unchecked values in a listbox? I have a user with several roles and I want to only show the ticked roles in the listbox.
Secondly, can you create a hyperlink on listbox values? i.e, if I click on "Manager" in the roles listbox, it follows that to another form and opens the record about managers?

I need for Access only to sum the "hours worked" of my payroll data, only if another field, "pay code" meets a certain criteria.
In Payroll, some codes are used to designate actual hours worked like REG (Regular Hours) and like OTS (Overtime Straight) while other codes are added as "premiums" to these hours and do not mean that you actually worked those hours, like OTP and HOD (Overtime Premium & Holiday Premium). The hours are only added as a reference to the actual hours worked they are attached to. Their units should not be counted as hours worked.
I want Access to 1) Group By Cost Center, 2) Sum "Hours Paid" that are tied to a REG or OTS (only), but 3)Sum the Earnings for all pay types.
Basically, (in excel-like terms: Hours Paid Column= SUMIF of Paycode = REG OR OTS. But Earnings Amount Column= Sum of all Paycodes)
Cost Center
Job Type
Hours Paid
Pay Code
Earnings Amount
20530
Security Guard II
7.5
REG
190.37
[Code] .....

I have a table (Table 1 let's say) which contains a list of numbers that all have unique ID numbers in another table (Table 2). Is there a way to create a column in Table 1 that will link those unique ID numbers from Table 2 to their corresponding values in Table 1?
What happened was I imported a list from Excel and there are frame numbers which are unique (but I still gave them an ID) and I now realize that I have another table which lists all these products, which all contain this frame number. I would like to replace the frame number with the correct ID number.

Hi
In query:
How can I set the values?
Select [Vendor Name]
where [Date Received] = [Please enter the date]
From Input
Union
Select [Vendor Name]
where [Date Received] = Input.[Date Received]
From Month_Report
Can I pass the date value from Input to the Month Report date value. Because they are same date. This way I just input once.
Does that run correctly?

I have designed a form with a Listbox which pulls information from a query.
The listbox multiselect vaue is set to NONE.
As I select a specific record, I have an update query which runs silently in the background through an implemented macro. The subroutine then requeries the listbox to update the latter with the latest values.
Here is a description of my problem:
1. After running the update query and upon requerying the listbox to update its values, I lose my initial listbox row selection. It is imperative that the listbox defaults to the user initial selection after the update requery action occured (note that this would be the same record).
I have searched the forum, but did not find a specific answer.
I thank you in advance.
