Queries :: Sequence Number Reset At Each ID Exchange
Nov 18, 2014
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 Microsoft Access database with SQL Server backend with 10000 records in my table, I have a autonumber field and in my database the purpose of the autonumber field is just to keep the record sequence (not to treat as a unique identifier) and I don't want to use a number field to manually enter the sequence. Whenever the record is deleted or the user won't save the record, it put gaps in the record sequence, Is there any way to refresh the autonumbers automatically "After delete confirm" event or "After Insert/update" even.
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?
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.
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.
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?
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?
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.
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.
I am currently working on a db to handle our FMLA time. I keep a continous form that totals the time used and subtracts that from the starting amount. One year after the time is used their total should grow. I am looking for some code that will not calculate any record that has a date beyond one year from the current date.
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
...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".
I do not want to use AutoNumber to generate my Stock Control Number. I need to somehow automatically generate a number so that when I enter data and then make an error it does not mess up the numbering system like AutoNumber does.
I am a novice who is will to try to do what it takes to get this going properly. I cant find anything online relating to Access 2010.
There is a autonumber column in one table Order.Everyday I need delete records in Order and then append records into it.Doing so, autonumber keeps on increasing.Is there any way to reset Autonumber from 0 after deleting records?
I have a table which will be completely emptied and refilled. The table has a field autonumbered it is also the primary key. When the table is refilled I want this field to start from 1. How can I do that. Yes some people will say this subject has been discussed search for it. But here the issue is somewhat different we have an existing field and I do not want to compact the database each time the procedure runs.
I have a BE database that we have been using for over a year. I imported data from an external database into this database. Now I've found that my Autonumber has reset to a very low number -- that was imported from my external database. Is there a way to change this autonumber BACK to what it was and increment up? The lowest autonumber in this database is 275944, so I don't have to worry about duplicates in the near future. I would like it reset to 457230, or at least higher than that number.
