Missing Null Value In Query
Jan 4, 2006
Yes, another of my query troubles. I am running a query that is showing the number of demos booked, number of demos executed, then the percentage of demos executed. I have 2 demos that have 1 or 2 booked, but they have not been executed. They should show up in the query so I can get a percentage for them, but they do not. Here is my SQL:
SELECT [Promo count].PromoNo, [Promo count].[# of Demos], Count(Query6.Status) AS CountOfStatus, IIf([CountOfStatus]=0,0,[CountOfStatus]/[# of Demos]) AS Percentage
FROM [Promo count] INNER JOIN Query6 ON [Promo count].PromoNo = Query6.PromoNo
WHERE (((Query6.Status)="E"))
GROUP BY [Promo count].PromoNo, [Promo count].[# of Demos];
Anyone know what may be going on?

Hello all,
A bit of a weird one, I've got a query and the criteria for showing records is that one particular field is null. However the query is showing records with the values in the field chosen for the Is Null.
Not sure why this is happening, has anyone come across this problem before?
Thanks.

I am using an Access 2010 DB to keep track of a schedule. Essentially, at least one person needs to be signed up to work for every hour of every day in a week.
Tables:
Days with 7 records
Hours with 24 records
Workers with as many people that sign up to work the different hours
Schedule signifying the worker, day, and hour which are signed up.
As of now i have a query that relates these results and gives me a line detailing the worker/time information for the slots that are signed up for.What I'm TRYING to do is to create a query that gives me BLANK worker info when there is no one signed up for a particular hour.Currently my Schedule table has the following:
WorkerID | DayID | HourID
----------+---------+--------
1 | 5 | 12
4 | 5 | 13
16 | 5 | 15
What I'm looking to do is have this table matched up with another table (or query) that provides every combination of day/hour. When an day/hour combination is skipped, the query will be able to "fill in the blank" with a row. Like this:
WorkerID | DayID | HourID
----------+---------+--------
1 | 5 | 12
4 | 5 | 13
| | 14
16 | 5 | 15

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

I have what seems to be a fairly simple question.
There are two tables in my database. A and B. Each table has the same criteria: Name, Number, and Date.
I have created a formula in my query which will add the Number fields together when they both have the same name. My problem is that when there is not a row for a particular name on table B, the calculation does not list that row in the results.
I would like for my calculation to insert a zero in the space and add Number.
I have tried the Nz function, but this results in a missing name and date and just the numbers are shown.
How do I get the results to show a row where the name is only on one field and still make sure that it places a zero in its spot and add the zero and the other number together based on the name.
Thank you in advance for any assistance.

I have an ID field that is text. Here are some example ID's. The number is generated automatically and the letter is added by the user.
A10565
52073
C20633
RMA18941
I need to start numbering new id's automatically. I don't want to repeat numbers so I need to know which numbers have been used. So I am trying to remove the letters preceeding the numbers. However I can't seem to get rid of the records with more than 1 letter. Here is the what i've tried in the query -
test2: Left([ID],3)
newnum: IIf([test2]="A" Or [test2]="C" Or [test2]="F" Or [test2]="H" Or [test2]="R" Or IIf([test2]="RMA",Mid([ID],4),[ID]),Mid([ID],2),[ID])
after that is run this is what i get -
10565
52073
20633
MA18941
They are fine except the last one - MA18941 needs to be 18941.
I know I am missing something simple

I want to use a column in a query to show where data is missing in other fields.
In excel I have used this statement:
=IF(COUNTA(I5:J5)=2,"","error")
Basically, I have two fields PRICE and WEIGHT. I want a column in the query to show 'Error' (or any kind of flag) when either (or both) of these fields are blank.
Hope this makes sence.
Any advice?
Thanks

Hi.
i.e..............
Table A has records 1,2,3,4,5,6,7,8,9,10
Table B has records 1,2,3,4,5,6
How do I create a query that returns values 7,8,9,10 for Table B when I compare Table A and Table B?
What sort of query do I need? I tried the "Unmatched query" but this did not get the result I wanted.
Thanks for reading.....

I have a table for stock with two fields, KEY and DESCRIPTION; a table for manufacturers with two fields, KEY and NAME; and a third table which links to them both with a many-to-one join with three fields, KEY, STOCK-KEY and MFR-KEY. What I am trying to do is write a query that for a given manufacturer (entered via a parameter) shows a single line for all stock records that are NOT linked to it via the third table. I am sure it should be simple but all my attempts fail to exclude stock linked to the manufacturer if it is also linked to another manufacturer. Any ideas?

Hi
I have inherited a database that contains details of staff training data and the tables contain the following:
Personal Information Table:
PersonalID
Surname
Forename
EmploymentStatus (this contains either Staff, Operative, or Supervisor)
Training Courses Table:
CourseID
Course Name
Course Description
Supervisor (Yes/No)
Operative (Yes/No)
Staff (Yes/No)
Training Courses Attended Table:
RecordID
PersonalID
CourseID
Date
Each of the courses in the Training Courses Table should be attended by one or more of the groups identified in the EmploymentStatus field (ie. Supervisor, Operative, Staff) and the relevant field in the Training Courses Table is flagged eg.
Training Courses Table:
CourseID, CourseName, Supervisor, Operative, Staff
100, basic safety, Yes, Yes, Yes
101, safety management, Yes, No, No
102, working with ladders, No, Yes, No
103, VDU, No, Yes, Yes
I need to identify which individuals have not attended the courses that they should have been completed (ie. compare courses attended with the list of courses associated with the EmploymentStatus associated with individual staff members, and identify which courses have no attendance dates).
How can I structure the query, I can't see how to do this with the existing tables, but I think it should be possible, but my Access expertise is just not good enough to work through this.
Any advice would be much appreciated.

I am working with a normalized database that has MANY tables. Most of these consist of lists of options to select from for the primary table. The primary table is linked to the secondary tables (and those to tertiary tables) by Primary Key ID fields, and the other tables contain additional information.
For Example, the Name list table is related to the Actions table by the SSN field, and the Actions table is related to the PayStatus table by an ID number collected by a lookup field.
When I pull all three tables into a query to display all the information related to a particular individual an his action, there are more records if I remove the PayStatus table from the query. It seems to only pull reports for which a PayStatus has been selected.
How can I get the query to display ALL the records, whether or not the individual has a pay status? Whether or not the individual has one is irrelevant, but I want his name to be displayed, whether or not he has one.
Thanks for any suggestions.

I have an Access MDB which uses a number of queries, reports, forms, and tables, and a module. When I make a new replica of it or try to synchronize it, several of the queries don't get put into the replicas. The data, however, appears to be synchronized perfectly.
I'm wondering if our use of replication is causing the problem. I have the database application running on three computers so different people can add data. The computers aren't networked. What we do to synchronize is copy the file used on one computer onto a CD-R, then copy that back onto the main computer, and then synchronize it there. Then we reverse the copying to put it back on the secondary computer. Am I doing this wrong?
Any idea of how to fix this problem?

I have an asp page which modifies articles in my access database.
I added a field in the db called "Blocco" which is a checkbox field.
The code (working) which the page used before was (I'm copying just the part that modified will cause the problem):
Code:SQLModifica = " UPDATE [Articoli] SET Articoli.Sezione = '"& FSezione &"', Articoli.Autore = '"& FAutore &"', Articoli.Titolo = '"& FTitolo &"', Articoli.Podcast = '"& FPodcast &"', Articoli.tags = '"& Ftags &"', Articoli.Data = '"& FData &"', Articoli.Ora = '"& FOra &"', Articoli.Letture = "& FLetture &", " If FBozza = "si" ThenSQLModifica = SQLModifica & "Articoli.Bozza = True "ElseSQLModifica = SQLModifica & "Articoli.Bozza = False "End IfSQLModifica = SQLModifica & "WHERE Articoli.ID = "& FID &" "If Session("BLOGAdmin") = False ThenSQLModifica = SQLModifica & "AND Articoli.Autore = '"& Session("BLOGNick") &"' "End IfSet RSModifica = Server.CreateObject("ADODB.Recordset")RSModifica.Open SQLModifica, Conn, 1, 3Set RSModifica = Nothing
After adding a radio type field in the form called Blocco (with yes or no values, working like the existing field "Bozza") I've modified the code adding something to update the db:
Code:SQLModifica = " UPDATE [Articoli] SET Articoli.Sezione = '"& FSezione &"', Articoli.Autore = '"& FAutore &"', Articoli.Titolo = '"& FTitolo &"', Articoli.Podcast = '"& FPodcast &"', Articoli.tags = '"& Ftags &"', Articoli.Data = '"& FData &"', Articoli.Ora = '"& FOra &"', Articoli.Letture = "& FLetture &", "If FBlocco = "si" ThenSQLModifica = SQLModifica & "Articoli.Blocco = True "ElseSQLModifica = SQLModifica & "Articoli.Blocco = False "End ifIf FBozza = "si" ThenSQLModifica = SQLModifica & "Articoli.Bozza = True "ElseSQLModifica = SQLModifica & "Articoli.Bozza = False "End ifSQLModifica = SQLModifica & "WHERE Articoli.ID = "& FID &" "If Session("BLOGAdmin") = False ThenSQLModifica = SQLModifica & "AND Articoli.Autore = '"& Session("BLOGNick") &"' "End IfSet RSModifica = Server.CreateObject("ADODB.Recordset")RSModifica.Open SQLModifica, Conn, 1, 3Set RSModifica = Nothing
The page itself is loaded with no errors but when the form takes action I get this:
Syntax error (missing operator) in query expression 'True Articoli.Bozza = False'.
why? I've just used the same code that worked with the field "Bozza" (which is a checkbox field too)
Sorry for my english

I'm trying to create a single, Update Query in Access 2007 that does all of these 3 things:
Update (skipping zero-length values)
Append
Automatically handle missing Fields without showing any "Enter Parameter Value" prompts.
I've managed to accomplish the 1st & 2nd items on my own, but I'm stumped on the 3rd. In essence, what I'm looking for is a way of telling Access to automatically use a zero-length/null value for any missing Field(s) the Query encounters, so long as it does not involve manually modifying the Table beforehand. Automation is key. And that's where you guys come in.
Attached, is a diagram of the desired results applied to a set of sample Tables. And here's the SQL code for the Update Query adjusted to work with those sample Tables:
Code:
UPDATE Table_1 RIGHT JOIN Table_2 ON Table_1.ID = Table_2.ID SET Table_1.ID = NZ([Table_2].[ID],[Table_1].[ID]), Table_1.Company = NZ([Table_2].[Company],[Table_1].[Company]), Table_1.Address = NZ([Table_2].[Address],[Table_1].[Address]), Table_1.Phone = NZ([Table_2].[Phone],[Table_1].[Phone]);
