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?
View RepliesI am looking to make a table which adds a sequence number to my records.
Example data would look like this

I have two tables - one with parent Records, the other with child records. The ID links the two tables .I want to add a sequence number on the child table which resets at each ID change. What would be the best way to accomplish this?
Code:
PC_ID ID Name Address
P 1 Parent1 Address1
P 2 Parent2 Address1
PC_ID ID Name Address SEQ
C 1 Child1 Address1 1
C 1 Child2 Address1 2
C 1 Child3 Address1 3
C 1 Child3 Address1 4
C 2 Child1 Address1 1
C 2 Child2 Address1 2
C 2 Child3 Address1 3
I have a set of transactions with a Unique ID field and a date. I want to add a field based that gives me the sequence of events for each Unique ID in order of when it happened.
For example, if customer X has 6 transactions, the sequence field would have a number (1-6) in each record that corresponds to the order in which those transactions occurred. The first transaction would have the number 1, the second would have the number 2 and so on.
I do same thing each month and would like to make it easier/faster: is there a way to run many queries, one after another?
I cannot use macro, cause Run SQL is restricted to 255 characters and my queries SQL codes are longer than that.
Is there a way to run them in a row? Like run query1, wait till its finished, then run 2..3..4.
791335.12pack. This is the object that is in one of my access fields. I need to extract the 12 and place that in another column called qty.

My database includes two separate dates related to a vehicle purchase and default payments resulting in repossession. I need to find out how many weeks passed between those dates.
Example:
03/14/12 Date of automobile purchase
06/06/13 Date of last payment before default
How many weeks in between? And then I need to average all of those figures so my company can see the usual week-term time frame that our customers are defaulting and getting repossessed.
I receive a report daily. From this report I need to calculate the number of successful backups within a window, and number of successful backups outside a window. The window is 7:00 a.m. The column contains date and time (10/15/2014 7:00 AM). Right now I have written the following query =Date() And > #7:00:00 AM#
I do not get any results even though there are 79 records that fit the criteria.
In the attached image I was trying to calculate number of working days(throughput) b/w item received_date and item_released date by using datadiff with "w" interval . but if I use "w" interval it brings value zero .but if I use "d" interval then it brings result with inclusive of Saturdays and Sundays.i don't need that.
How to calculate the number of working days exclusive of Saturdays and sundays.
I'm trying to calculate the number of days between two dates using the iif statement
Fields:
[LDW] "Last Day Worked"
[ReturnedDate]
DESCRIPTION: If ReturnedDate is null, then calculate the datediff "d" between LDW with Now(), if not, then calculate the datediff "d" between LDW with ReturnDate.
I tried this but it didn't work at all.
Days Absent: Iif(isnull([ReturnedDate],(DateDiff("d",[LDW],Now())),(DateDiff("d",[LDW],[ReturnedDate])))
I want to count number of mountpoints appear in the table.
As below sample table,
- Different mountpoints will appear, based on number of server using it. As you can see, the mountpoints will have repeating name based on number of server using it.
- The Count_Mountpoints will calculate number of total Mountpoints appear in the list.
MountpointsUsedbyCount_Mountpoints
/a/ins2server12
/a/ins2server22
/a/ins1server31
/b/ins2server31
/b/ins1server41
I only managed to get number of TOTAL mountpoints.... but by individual's mountpoint total count...
The title probably doesn't give an idea of what I need, so here goes.
We currently have reference #'s for our bills that include the date requested in mmddyy format, the first 3 letters of the customer, the initials of the order taker and finally a sequential number to show the sumber of bills that day.
example: 120705SEAGMM02 2nd order taken by GMM for Seagate on 12/7
120705SEARLH01 1st order taken by RLH for Seagate on 12/7
I want to generate this number automatically based on the date entered and the initials given of the user. We only deal with one customer at our desk so that will always be "SEA".
I have a query that generates the first portion (date, customer, and initials):
SELECT Format([REQDATE],"mm") AS [Month], Format([REQDATE],"dd") AS [Day], Format([REQDATE],"yy") AS [Year], Format([REQDATE],"mmddyy") AS [Both], [Both] & "SEA" & [PickUpReqData]![INITIALS] AS REFNO
FROM PickUpReqData;
But I can't seem to get my head around the part of generating the number. I know I had done this in a database I created 2 jobs ago but all my files were flooded out in Katrina. (I have since relocated to Atlanta, although I'm not looking for sympathy. But I will take what I can get!)
Anything to point me in the right direction will be appreciated. I am looking to have this on a form and feed the REFNO field in the PickUpReqData table.
Thanks.

Basically I have a report that shows any 'Issues' that wasnt closed within the KPI Target.
I have the report working, but I simply want to do a count of how many days the observations overran the 'Target Date of Closure'.
The report also shows observations that are not closed but passed their Target Date of Closure. These observations will not have a 'Actual Closure Date', but I would like to still have a count of how many days its overrun closure.
This is a formula I tried to piece together but obviously not correct as it's not returning anything;
IIf(IsNull([Issues]![Actual Closure Date]),DateDiff("d",[Issues]![Target Date of Closure],
Date()),DateDiff("d",[Issues]![Target Date of Closure],[Issues]![Actual Closure Date]))
I am trying to count how many of the "same" and "differences", as well as calculate the percentages of the number of "same" over the total amount. To clarify, I work at a nursing home, and I need to calculate the number of people who were admitted to our facility and then to the hospital for the same diagnosis, and a different diagnosis. Then, out of the total number of people who were admitted to the hospital from our facility, I need to calculate how many of those people had the same diagnosis or a different diagnosis.
Also, I need to categorize these diagnosis by each type of diagnosis.
Hi!
1. If accidently a record or two in a sequence are deleted, how will you know that this has happened! What type of validation can be enforcedto prevent this?
2. How do you make your Tables, Quries, Forms, Reports, Macro tamper proof?
Please help!

I have a query that captures date values from a table based on a between function that works fine. What I would like to do is associate a sequence number fro each date value returned and either perform a make table or leave it as a select query. If I create a table I know that I aam able to add an autonumber field but the query is executed frequently and performing the addition of the autonumber field is not feesible. Any thoughts how I can generate the sequence number each time the query is executed?
Thanks
i want to know such a method that if i give a number, the database find me the next available number from the given list in the table.for example, i have a table having list of numbers like 6500, 6501, 6502 etc, I give the number 6500, the database should give me the next available number in sequence from that given list in the table.

All I need is a way to number rows with a value higher than the previous for that particular ID_NUM.
I'm trying to code for a 'duplicate record' button on a form that, as well as copying the values of all the controls of the previous record to the new record, makes a certain control (which contains a number) increment as appropriate.
There are two controls on the form which contain the start and end values of a numerical sequence (of potentially any length) e.g. the range 48-82 shows 48 in text box boxREGSEQSTART and 82 in the text box boxREGSEQEND OR the single value 99 shows 99 in text box boxREGSEQSTART and text box boxREGSEQEND is empty. In a record, the value of boxREGSEQEND would always be higher than that of boxREGSEQSTART or would be blank.
The appropriate incrementing action would be:
After clicking 'Duplicate Record' button, If there is no value in boxREGSEQEND in the record being copied, then in the new duplicated record the value of boxREGSEQSTART should be 1 greater than the value of boxREGSEQSTART in the record it has been copied from.
i.e. the record being copied is records a single item, a single value, and the next record should show the sequence moved on by one
OR
If there is a value in boxREGSEQEND in the record being copied, then in the new duplicated record the value of boxREGSTART should be 1 greater than the value of boxREGSEQEND in the record it has been copied from.
i.e. the record being copied is recording multiple items, a sequence, but the next record should still show the sequence moved on by one
I can get the duplication to work no problem, and I can get the incrementing to work fine for the first set of conditions, but can't for the life of me get it to increment when there is a range!
The logic (in my head, expressed as best I can in the macro language ) for the whole sequence of actions goes like so:
RunMenuCommandCommand SelectRecordRunMenuCommandCommand CopyRunMenuCommandRecordsGoToNewRunMenuCommandCommand SelectRecordRunMenuCommandCommand Paste
If [boxREGSEQEND]=[IsNull] Then
GoToControlControl Name boxREGSEQSTARTSetValueItem = [boxREGSEQSTART]
Expression = [boxREGSEQSTART]+1Else
GoToControlControl Name boxREGSEQSTARTSetValueItem = [boxREGSEQSTART]
Expression = [boxREGSEQEND]+1GoToControlControl Name boxREGSEQENDSetValueItem = [boxREGSEQEND]
Expression = [boxREGSEQEND]=Null
Which I would assume would tell the program to copy the current record, make a new one and paste the copy, then if there was a range recorded in the original, start the numbering of the new record one number higher than the end of that range and clear the way in the new form in case it also records a range, otherwise just increment the sequence along by one.
Hi -
Suppose I have a generic query that returns a group of records.
Is there some way to generate a field containing the number sequence of each record? E.g. if there are 10 records, generate the numbers 1 through 10?
Must be a simple way to do this, I'm just a bit dense today...
Thanks,

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 data in a table that looks like the first table and I would like to write a query to update the sequence so it looks like the second table.

Occasionally a user of mine needs to reset a sequence number in a table.
A few months ago I made him a simple app that has two text entry boxes and a button. The first text entry box uses a dlookup:
Code:
=DLookUp("sSessionNumID","qryGetAPIsessionLastValue")
...the other textbox ties to an update query, which updates the sequence number with the new value supplied by the user. Simple.
Then about a week ago it stopped running the dlookup part - nothing shows in the text box that is to show the current sequence num.
Oddly, if I enter a value in the update text box and press the button to update the sequence number (which still works) -- the previously dormant dlookup textbox now shows the new value - so it works ...it just doesn't want to work on this one workstation unless the update query is run first.
What can this be? The update button merely calls a DoCmd.RunSQL with both an insert (storing old value locally in ms access table) and an update (updating the sql server table's seq number using an ODBC DSN and sql server driver).
It's almost like the dlookup falls asleep now and won't wake up until the update is run...
I have a Primary Key field named Member ID(Number format) in a Table named Mail List. The field is populated with existing ID numbers and my need is to use my Member Entry Form to increment by 1 from the last entry.
I have gleaned from other references that this can easily be achieved by the following entry in the Default Value of the property sheet for the relevant field;
=DMax("Member ID","Mail List")+1
The Form saves without error but when I attempt to add a new record in the entry form, the ID Number reads "#Error".
