Query To Extract Greatest Number
Aug 14, 2007
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 do have a module to extract a number from a string :
Public Function ExtractedValue(strSent) As Double
If IsNull(strSent) Then
Exit Function
End If
Dim strTemp As String
Dim intLoop As Integer
[code]....
My problem is that the string I do have is like:
19.0 EA
195 PAC
42 M
150 L
the problem is that when the number is like 19.0 EA the value I get is 190, in reality it should be 19. The rest is fine as there are no dot's.

Hello,
I would appreciate if someone could help on this problem.
What I want to do is to add a field in a form that would automatically show the date of person's birth after entering the persons ID. For example, I enter 39101012345. The first number (3) shows only the gender so I don't need it. The next 6 numbers show the date of persons birth - it is 910101 and it means that the birthdate is 1991.01.01
I need this field in a date format because later I will have to do some calculations concerned with the birthdate of that person.
Thanks in advance!
p.s. beer for help is quaranteed! :)

How to extract or calculate the number of records in a sequence - e.g. in a table/query ordered by ID and date, the number of consecutive records by date for a given ID that have a value >= 50 in a given field. Is there a way of doing this purely within a query, or would I have to resort to a VBA loop through a recordset and keep a count of the consecutive records that match that criteria?

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.

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:

I am trying to do some simple table operations. I have a field (Date) containing dates, and an empty field called Day.
I want to extract the day number from the Date field, and write it to the Day field.
I didn't get very far until I ran into trouble when setting my recordset. I get the error "Too few parameters, expected 1". Clicking "Debug", will highlight the code line "Set rs = db.OpenRecordset(sqlString, dbOpenDynaset)".
So far, my code looks as follows:
Code:
Private Sub Command16_Click()
Dim db As DAO.Database
Dim rs As DAO.Recordset
Dim sqlString As String
Dim dataDay As Byte
'Open connection to current Access database
Set db = CurrentDb()
[Code]...
I am not very familiar with the various types of recordset settings. I just want to be able to read data from the Date field, and write data to the Day field.

Hi there,
I am a relative newcomer to Access, and am trying to work out if there is a way to isolate email addresses in a line of text, and delete all the text around them.
I have basically got a column which contains blocks of text and I want to extract the email addresses that are embedded within them. Does anyone know if this is possible by running queries?
Thank you in advance for any help! :confused:

Hi
If i wanted to run a query from customer records in my database and wanted a list of specific postcodes that matched the criteria how would i do this?
For example each customer records has a postcode BD4 4KL, LS9 7YH ETC
I want to categorise each postcode set to see for example all the customers with postcodes begining with have ordered factsheets.
In the criteria part of the query how would i write it so it only extracts specific postcodes from the database from the ones i require
e.g "HU1, HU2, HU3 HU4" - checks database - returns all postcodes beginning with this.
Please help me!
Thanks

Hi, newbie question.
I have an existing select Query, that has a field of dates. I want a new select query based on that source that shows all records except for the one with the largest value date. There will be no duplicate dates. I tried:
SELECT Q_Tasks_Accs.End AS NotLatestEnd
FROM Q_Tasks_Accs
WHERE (((Q_Tasks_Accs.End)<(Max([Q_Tasks_Accs].[End]))));
but when I run the query I get error message:
"Cannot have an aggregate function in WHERE clause(Q_Tasks_Accs.End)<(Max([Q_Tasks_Accs].[End]))"
I clicked on Help but did not understand what it said. So any help from here would be appreciated.
Thanks

I need to break up part of the value in one of my fields. I can do it in Excel by identifying the position of the dash with eg. =FIND("-",D13) And then using it in a LEFT function. Or using the text to Columns wizard.
How can I do it in a query, there is no find function. If there is an equivelant what is it?
Sample data:
22DF-RED
33AF-0
44TG-Blue
I need only the data to the left of the Dash
Thanks

I am trying to construct a query to extract mailing addresses from a table. I have individuals entered into a table (a separate record for each person) but if they are married I want an address such as Mr and Mrs J. Doe so that only one address label is printed off so that only one letter is sent out. If one of them dies then the address should only go to the surviving party eg Mrs J.

I have a table with a field named BinNo which has a list of items with a bin no in the format 1.234( this number can be any number up to 6000.9999).
Is there a way for me to have a field on a form where I enter a number (i.e 1) and it lists all the items with a 1 before the decimal point but not 10 or an other number with a one in it. If I enter 10 then it will only give me the items with 10 before the decimal point and not 11 etc.
I have a query that pulls all the data into it but I only want the query to show the items relating to the number I enter into the form field.

I am trying to loop through a query results to extract email addresses from a query result.
I have the following code
NameCriteria = Forms![MainMenu]![tbl_Course_Details]![Course_Name].Value

Dim db As DAO.Database

I have a Table1 served by Form1..It is a list of: UnqID, process, quantity, totaltime(in seconds).I want to click on a record to bring up a filtered Form2 with the chosen record on it.What I want to be able to do is to now split the quantity (and the time) and put these new records back into Table1 and delete the original record
EG
ID1,10,write a report,2400
I want to delete this and replace it with two (or three/four etc) replacements, but still adding up to 10 quantity and 2400 seconds so that the new data could be:
ID2,5,write a report,1200
ID3,5,write a report,1200
My initial thoughts are to create a holding table to:Append filtered data on Form2 to a holding Table1hld (i don't know how to do this) delete data in Table1.then enter the new quantities into a holding Table2 (that I will input myself) and then append (through a series of queries back into Table1).The first problem is how to append (and subsequently delete) the filtered record from Form2 to Table1hld.

Well, here's my database :
Name : String
Address : String
I want to add an automatically generated column, "no.", to show which number it's in. Like this :
No. Name Address
1. A Unknown
2. B Unknown2
The problem is, I can do that with Auto-Number, but if the user delete row 1, the number in row 2 is still 2, not 1.
Is it possible to generate query that have "no." column in it ?
