Find Missing Numbers

Jan 1, 2006

I think this would be done though a query but i am not sure, any help or examples would be useful on this on.

Question:

Is there a way of getting access to find missing numbers. for example if some one enters 0 - 5 then access will pull the following numbers 1,2,3 & 4.

I am not sure if this is possible so any help would be good.

Alastair

P.S. HAPPY NEW YEAR TO ALL.

Queries :: Unable To Find Missing Sequential Numbers In A Text Field

May 5, 2013

I am trying to create a query to find missing sequential numbers in a text field. I am using this specific field as a case number which is designated as two letters, the # sign, two digits indicating the year, a dash, and then a four digit number; For Example: AB#13-1234.

The reason for this query is to tell the user of this database that a specific case number has yet to be entered and needs to be. The case numbers are unique and will never be referenced more than once.

My table name is "MainDataTbl" and the field i'm trying to find the missing case numbers is titled "CaseNumber".

Queries :: Match Up Two Tables - Removing / Changing Numbers

Jul 12, 2013

Okay, this one should be simple and can be solved in one of two ways. I have two seperate tables with a 12 digit identifying number that is ALMOST exactly the same in each. I am trying to match up these two tables, which works amazingly well, except for the occasional case where the 12 digit ID (which is called API) ends in 01, instead of 00. The last two digits do not make a difference at all, but in one table it will end in 00 and the other it will end in 01, even though they are the same record.

Basically, it looks like this...
Table 1---------------Table 2
541236554700-----541236554700
541236123700-----541236123700
443231246700-----443231246701

So basically, in my final query, the last entry will not show up since these two are not related by this API (ID) number. Any way to either replace the 01 on the end with 00... OR to remove the last two digits?

Missing Numbers

May 22, 2007

I have a sequencial number in my data base. It counts 1,2,3 all the way to 302344. I want to find missing records. How would I come up with the missing records in a separte database. In other words if I had 1,2,4,5,8,9. I would want to have a database that would show me 3,6,7 since they are missing.

Find Duplicates That Don't Match Single Field

Jun 5, 2007

Hello all,

I am sure this must be simple, but I can't get my head around it.

I have a query that looks at client bank account numbers, and finds duplicates.

There are a LOT of duplicates, because we have several accounts for the same person.

What I would like to do is find all the records where the account number and sort code match, but where the account NAME is different.

I am trying to find any records where the same account number is being used on more than one account.

All the fields are in a single table.

This is what I have so far, which just finds duplicate sort codes and account numbers;
SELECT CPL_ACCOUNT.ACCOUNT_NUMBER, CPL_ACCOUNT.SORT_CODE, CPL_ACCOUNT.BANK_NAME
FROM CPL_ACCOUNT
WHERE (((CPL_ACCOUNT.ACCOUNT_NUMBER) In (SELECT [ACCOUNT_NUMBER] FROM [CPL_ACCOUNT] As Tmp GROUP BY [ACCOUNT_NUMBER],[SORT_CODE] HAVING Count(*)>1 And [SORT_CODE] = [CPL_ACCOUNT].[SORT_CODE])))
ORDER BY CPL_ACCOUNT.ACCOUNT_NUMBER, CPL_ACCOUNT.SORT_CODE;


Thank you!

Finding Missing Numbers In A Sequence

Feb 1, 2005

Hello, I have no idea what to search for to see if someone else has already asked this question. I've tried several things with no luck. So here goes...

I work in a library. We deal with thousands of journal subscriptions--we cancel our subscriptions and order new journals all of the time. Every paper journal we have is assigned a unique number, called a ZP number. When we throw out a journal, that ZP number can be assigned to a new journal.

I would like to find the earliest missing number in the sequence without having to check manually. Is there a way I can do a query or something to find missing numbers in the sequence? The ZP numbers start with 1 and go up to 9999.

So, I have two fields: Title and ZP#.

How can I do this?

This is a cloned table, used solely for assigning ZP#'s, so it can be altered in any way--including adding records with blank titles for each missing number.

Thanks,
Siena

Finding Numbers Missing In Sequence

May 8, 2007

Hi

I've searched the forum and only found one thread which covers this but doesn't help me.

I have a table with peoples individual information in it.

Every person has a unique ID number.

I want to find the missing ID numbers when I delete a person so I can keep the numbers in sequence.

I am not using autonumber. The reason for this is coloured wristbands. Each wristband has a unique number and they are broken into 4 colours. each colour has a number range 1 - 300, 301 - 600, 601 - 900, 901 - 1200. Each person in the table has to have an ID number matching a wristband. The people are also broken into 4 colour categories. This means that not every range is filled before i need to start using the next range.

Hope that makes sense.

Modules & VBA :: Textbox Value To Loop Through Table And Find Match

Jun 26, 2015

I have an MS Access 2010 db that has a main form called switchboard. This has 4 command buttons that open diffrent forms. Also on the main switchboard form i have an unbound textbox called TxtUserName that captures the users environ"username" when the switchboard form is opened.

I have a table called "tblAccessUsers" that i manually enter who i want to use my db. This table will have up to 50 names added to it. Their is only one field name in this table and it is "User Login".

When the user hits any of the commandbuttons on the main switchboard form i need some code that will look at the value in TxtUserName and loop through tblAccessUsers for an exact match. If it finds a match then it will carry out the open form command or if not prompt the user with a message box.

My knowledge of Access and especially VB is quite limited. I managed to create this using a DLookup but that only returns the first record in the table. The logic works but it will not look past the first record.

Modules & VBA :: Define And Setup Array - Find Respective Numbers For A Text String

Apr 21, 2015

I need to find the respective numbers for a textstring when for

abcdefghijkl stand the numbers
79 81 82 83 84 85 86 87 88 89 91 92

The textstring to "decode" is for example is 'adgjk'

The result (79 83 86 89 91) should be added into a table by Looping.

rs.Addnew
rs("Letter")= myarray??
rs("corNumber")= myarray?
rs.update
rs.movenext

Something like this.

But I cannot define and Setup the Array, which should be the best way for doing this.

The Array does not change its Content nor its Dimension.

Both, letters and numbers are strings.

Missing Records (and Missing Updates)

Oct 7, 2005

Hi all

This is an ongoing problem I have had for 4 weeks now.

I have made a a system thats acts like a clock In/clock out Out system.

the structure is somthing like this
ID
Username
tblDailyLog
TimeIn
MorningBreakOut
MorningBreakOut
LunchOut
LunchIn
AfternoonOut
AfternoonIn
TimeOut

All fields apart from ID (autonumber) and username (String*255) are Date field (there are a few others like DateOfTimesheet etc but they arnt important here)

When a user arrives in the morning they make a record which they use for the day

They then have a form with a whole bunch of buttons which simply updates the correct field. For example they click the "Sign in for the Day" button and it updates the correct field with the current time.

Everything was going fine until people noticed that every now and again a sign in time dissapeared.

I have hacked myself to death trying to solve this problem but still the updates go Astray.


Now each time a time is updated the process goes somthing like this


1. the user opens their timesheet for the day (the RS is SNAPSHOT and no locks)

2. User Hits a sign in/out button
3. The record source is changed to "" and all buttons hidden (to ensure the record isnt locked and to make sure you dont do two things at once)
3. The table is updated with the new time (using some dynamic SQL)
4. The table is repeatadly checked using a DO loop to make sure the the correct time went in.
5. when the returned time value of the field matches the varaible used to update it, the form is returned to normal and the user carries on his/her merry way (if it never matches the screen should crash but this never happens).
6. A New record is added to another table called "tblbugfixinglog" which records which field was updated and when. This is so that I have two records in two different ways (figured if one went astray I could pull it back off the other)
7. Another new record is added to yet another table called tblSQLRecord, which simply logs all .RUNSQL statements that are executed.


I thought that the two extra tables (and the check that the record had been updated) would help me track down where the records are going missing, but this isnt the case.

Now it appears that some records arnt being added to tblBugFixingLog and to tblSQLRecord either and some of these tables are getting quite a few #ERROR's in them..

None of the tables are related to any other and i've no idea how #ERROR lines are appearing in a table that has 1 function... to recieve new records ... no editing, no viewing, no deleting.

Does anyone have any idea how these updates/inserts can go missing or create #ERRORs.
I've built plenty of Databases in my time and have never come across this.
__________________________________________________ ______________

This is the function I use to add a record to tblBugfixingLog and tblSQLRecord


Private Sub AddBugLog(ByVal TimesheetNumber As Long, ByVal FieldUpdating As String, ByVal NewFieldValue)
Dim TempSQL As String
TempSQL = "INSERT INTO tblBugFixingLog (TimeAndDateOfEntrySERVER,TimeAndDateOfEntryPC,Fie ldUpdated,NewEntry,UserID,TimesheetNumber,Computer AssetNo) VALUES (" & _
"#" & Format(ServerGetTime(Environ$("LOGONSERVER"))) & "#," & _
"#" & Now & "#," & _
"'" & FieldUpdating & "'," & _
"'" & NewFieldValue & "'," & _
"'" & GetNTUser & "'," & _
"'" & TimesheetNumber & "'," & _
"'" & fOSMachineName & "')"
' MsgBox TempSQL
DoCmd.RunSQL "INSERT INTO tblSQLRecord (Username,DateAndTime,Screen,TheSQL) VALUES('" & LoginInfo.sUsername & "','" & CStr(Now) & "','Add Bug Log function','" & CleanData(TempSQL) & "')", False
'CleanData is a function that removes ' and " from the SQL string so i can easily add the SQL string into the table
DoCmd.RunSQL TempSQL, False
End Sub

Public Function CleanData(ByVal DataToClean As String)
Dim TempData As String
Dim i As Integer
TempData = ""
For i = 1 To Len(DataToClean)
Select Case Mid(DataToClean, i, 1)
Case "'"
TempData = TempData & "`"
Case """"
TempData = TempData & "`"
Case Else
TempData = TempData & Mid(DataToClean, i, 1)
End Select
Next i
CleanData = TempData
End Function


__________________________________________________ ____


I have no idea how this can create #ERROR lines in the table when it is just added to and nothing else.

Does anyone have any clue to what may be happening here.

(Oh yeah and no matter how hard I try, I can't replicate the problem.... works for me every time no matter how harse I am to it!)

Please save what little hair I have left and give me some hope

Cheers
Homer

Queries :: Search For Multiple Plot Numbers Preferably In One Parameter Prompt With Comma To Separate Numbers

Aug 12, 2014

I'm having multiple problems with my database like things such as -

i'm currently working on the Query 2 - On the Phone database (ignore Query 1) and i want to search for multiple plot numbers preferably in one parameter prompt with a comma to seperate numbers. (this could be a multitude of numbers so i would like to be able to input as many as needed). Also when i do search on this query since the Criteria is a 'Between' Value i would expect everything between the 2 numbers input to show up - but a lot of numbers out of the range show up too - why is this? (The Numbers are like "69 to 136" and they will show up - but 1-69 and 136-170 would too

I would also like to implement the search results from Query 2 into the Form i currently have made but it just opens up a access table when the search is made?

i cannot link my database as it is too big for the server - But here are the Criteria for Query 2:

Plot No - (criteria = Between [Enter First Plot No:] And [Enter Last Plot No:])
Site - (criteria = Like "*" & [Enter Site:] & "*")
Product - (criteria = Like "*" & [Enter Product:] & "*"

The Query is the one im most concerned about , i can live without a form.

Numbers Stored As Text Convert To Numbers?

Ok so in excel I have some numbers that are stored as text. The reason being that they are zip codes and some begin with 0 and excel doesn't want numbers to start with 0....so when I import these into an access field that has an input mask for zip codes...will it convert these correctly since the field is a text with input mask?
