Queries :: Identify Missing Records Between Queries
Jul 14, 2015
I have a query that will draw down student details who have completed a course in a given month (May for example), i would like to use this data to identify those learners who are not enrolled on a course in the next Month (June for example). There is no field that denotes whether a student has left only that a course assosciated with their ID has a completion date within that Month. There are approx 250 records.
In my head it should work something like this
1) Identify all learners who finsihed a course in May (Identify learner ID, must have a course end date in that month)
2)Cross reference these against all those who started a course in June and identify the students that have completed in May but did not start a course in June.
Is it possible to store all those who completed (May) in a table/query and cross reference those who started in June and identify of the May completions who did not start in June?

I have a table [PickData] in a WMS (Warehouse Management System) database, that records details of each item picked. The key fields are;
[Movement] - a unique ID for a collection of items to be picked.
[ToAssignRef] - the order ID
[Product] - the product!
[Picked] - the date/time the item was scanned
[Pick Actioned] - the date/time the [ToAssignRef] was completed
[Reason] - A code to indicate why an item could not be picked - AKA F3'd
An operative would be allocated a movement, connected to the [ToAssign Ref], containing a number of products to pick. If an item can not be picked for some reason the operative presses F3 and selects a reason (no stock, damaged etc). These F3'd items (other stock allowing) will later be picked on a different [Movement]. I need a query to identify the subsequent [Movements] and the associated fields following the occurance of an F3'd [ToAssignRef] & [Product].
I have a query, but it runs very slowly (perhaps due to the DB size currently 780K records). Is this the right approach, is there a better (faster) way to do this?
Code:
SELECT PickData.ToAssignRef, PickData.Product, PickData.Picked
FROM PickData
GROUP BY PickData.ToAssignRef, PickData.Product, PickData.Picked
HAVING (((DCount("[Movement]","[PickData]","([ToAssignRef]='" & [ToAssignRef] & "') AND ([Product]='" & [Product] & "')"))<>0));

Hello again
Sorry, just posted this in reports, moved it now.
Could someone point me in the right direction please. I have seen a thread similar to this before but I can't find it now.
I have a query that is made up from 3 different queries.
These 3 queries show the stats totals in the last x weeks.
qry2Week (colleague stats from last 2 Weeks)
qry6Week (colleague stats from last 6 Weeks)
qry13Week (colleague stats from last 13 Weeks)
This query shows every day and also the above 3 queries are linked in.
qryAll (every day and 2, 6, 13week stats totals)
The problem is if there are no stats in the last 2 weeks no stats will show up at all.
If I take out the (is not null) from the individual queries I get duplicate lines in my main query (qryAll)
How do I show all the information without having duplicate lines.
Cheers
Kev.

Basically I would like to populate column three "OUTCOME" according to the following logic:
if train A10 has multiple destinations (we see this in the second column) then in outcome I woudl like to have "multiple destinations" if the destination is only one (in case of trains A15 and A16) , then I would like to have that city in column 3 "OUTCOME".

I have a table that holds information for a type of show and the base cost of the show. I am trying to make a query that gathers information for all the shows in the table and uses the Dlookup function to identify the base cost of that show. This will in turn be used in the same query to create a quote, but I can not get the Dlookup function to work and I am sure that I may be doing it very wrong.
The table is called ShowList. That table contains 3 fields, ID, Show Type, and Cost.
The query is called Venue Cost and will have a series of fields that work to develop some math on all items from another table called Venue Info. Venue Info uses ShowList to select the type of show.
What I want the query to do is look up the Show type from VenueInfo and then look up the base cost of the show type from ShowList. What I have been using is not working but is as follows:
DLookUp("Cost","ShowList","[Cost] =" & "[Venue Cost]![Venue Type]")

I have a relatively large database 65M, 42K records.
For some reason I seemed to have lost most (not all) of the queries I have written. However, if I go to file>database properties>contents, I can see all my queries there.
I certainly did not delete them. Any I idea of what’s going on ? I'm, using Acess 2000 on win2K. Might this be a resources / memory related issue?
Thanks

I have a query where I am geting the last 4 digits from an id. However my query when it returns the results misses out the leading zero from the results. For instance if I had an id of 12340567 the query should return 0567 but instead it returns 567. This is what I am using:Max(Right([Employee]!

I currently have query that looks at 2 tables that hold financial information. I am querying the data to do some adding and subtracting based off a financial class of a facility. The issue I am having is that one table may have a financial code that the other does not have but I still need to show that financial class for the facility.
My looks as follows
FROM [CashValue Link] INNER JOIN TCashValue ON ([CashValue Link].FINANCIAL = [TCashValue].FINANCIAL) and ([CashValue Link].Date1 = TCashValue.Date1) AND ([CashValue Link].FACILITY = TCashValue.FACILITY) AND ([CashValue Link].CLT = TCashValue.CLT)
I am sure I am over looking something.

I have a fairly simple query to weed out all the records in our database that are missing vital pieces of infomation :
Code:
SELECT Contacts.Name, Contacts.Address1, Contacts.Address2, Contacts.Town, Contacts.County, Contacts.Country, Contacts.PostCode, Contacts.Telephone, Contacts.Code
FROM Contacts
WHERE (((Contacts.Address1) Is Null) OR ((Contacts.Address2) Is Null) OR ((Contacts.Town) Is Null) OR ((Contacts.County) Is Null));
Is there anyway to count how many fields are missing for each record ?

How to fix some records in my access table. It is a huge table more than 12k records!
In one of the field there are some data missing. The logic to reconstruct them is easy but I am not sure how to apply it in Access.
I have three columns one is the student ID, Year, term1 and term2
ID Year Term1 Term2
1234 2001 001 002
1234 2002 002 002
1234 2003 002 003
1234 2004
1234 2005 004 004
3311 2001 003 003
3311 2002 003 004
3311 2003
3311 2004 005 005
In the above example student 1234 has a missing record in year 2004 which supposed to be Term2 in the previous year (i.e. 003) and Term2 supposed to be Term1 value in the following year (i.e. 004). Similarly for student 3311
ID Year Term1 Term2
1234 2001 001 002
1234 2002 002 002
1234 2003 002 003
1234 2004 003 004
1234 2005 004 004
3311 2001 003 003
3311 2002 003 004
3311 2003 004 005
3311 2004 005 005

I have 2 tables: one for repairs and the other for the billing for those repairs. There is a foreign key(record_num) in the billing table to match the primary key(prikey) in the repairs table. This works fine as long as the unit repair has been completed.
Now an employee wants to see records even if they are not completed and wants the rate to be $0.00 if the unit has not been completed. But by this method there is no record in the billing table.
My problem is if I have the 2 tables joined then I only see records that match both tables. Here is my SQL for the query:
SELECT DISTINCTROW tbl_module_repairs.end_user, tbl_module_repairs.pickup_date, tbl_module_repairs.complete_date, IIf([pickup_entity]="Storm","APS Storm","APS Field Tech") AS [Repair Pickup], tbl_module_repairs.mfg_part_num, tbl_module_repairs.manufacturer, tbl_module_repairs.module_type, tbl_module_repairs.incoming_module_sn,

I am trying to create a query which show me which of my customers in my database does not also contact a contact to go with it.
I have two tables; Customers and Contacts.
When I create a query I add the fields Company Name from the Customers Table and First Name from the Contacts Table. There are obviously other fields in both tables.
However when I run the query it does not not show me all the results. It only shows me customers if something has been entered into any of the fields in the contacts table for that Customer. I suppose this triggers a contact ID entry for that customer even if no Name has been entered.
However, how do I run a query to show me customer entries which have no contacts to go with them because no contact entry has been made for that customer?

I'm using the following for a field in a query:
ITINERANT: IIf([Day and Time1] Is Not Null,[Day and Time1],IIf([Day and Time2] Is Not Null,[Day and Time2],IFF([Day and Time 3] Is Not Null,[Day and Time 3],IFF([Day and Time 4] Is Not Null,[Day and Time 4],IFF([Day and Time 5] Is Not Null,[Day and Time 5]," ")))))
I'm getting the error message: Syntax error (missing operator).
I'm not very good at using the IIF statement.
I have 5 concatenated fields that may or may not have info.
I want to display all of the info or if blank; show nothing in the one field.
Also, would I be able to have a return after each of the 5 concatenated fields?Not sure how to do that in this statement?

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]);

I'm trying to make a sub form that displays the hours of an employee selected in a listbox. I've got most of it working but having a bit of an issue.
The info for thre query is in 3 tables:
tblStaff (name etc)
tblShifts (start and end times for days that this employee works)
tblDays (a list of days names so I can use numbers elsewhere)
My query looks like this:
Code:
SELECT tblDays.dayName, IIf(Nz([startTime],"")="","NWD",[startTime]) AS start, IIf(Nz([endTime],"")="","NWD",[endTime]) AS [end], tblStaff.staffName
FROM tblDays LEFT JOIN (tblStaff RIGHT JOIN tblShifts ON tblStaff.staffPK = tblShifts.staffFK) ON tblDays.dayPK = tblShifts.workingDay
WHERE (((tblStaff.staffName)=[Forms]![frmMain]![lst_myTeam] Or (tblStaff.staffName) Is Null));
This worked fine with a single user and some test data - it correctly displayed all days of the week, with start/end times on Mon and Tues where I had entered shift information, and "NWD" against all other days.
However, when I add a couple more employees to the mix it shows the correct info for the first employee, but anybody else it will only display days where person 1 doesn't have any hours. I haven't entered any hours for the new employees, but the query should still display Mon-Sun with NWD in every column. It shows Wed-Sun but Mon and Tues are missing.
I've tried different join types but they all come back with "ambiguous joins" error when I try to run.

Hi
i have a query that takes fields from various related tables to give me the information that i want
The primary table has 199955 records
The query displays only 199939
16 recordss are missing
I know why this is: the primary table (CWT reqd equip) has a field on it that is a primary key on another table (cwt Equip). On "CWT reqd equip" 16 records must have an entry in this field that is not present on the table where the entry is a primary key (cwt Equip).
I dont know how to identify what these 16 records are on the primary table. I want to get rid of them so i can enforce referential integrity between the two tables.
can anyone help? Have i wrote this clear enough?
thanks
p.s i've attached a doc showing how the query is built. the other tables other than the two i mentioned aren't important, for this.

After some research it seems i should be using
SELECT Count(Distinct [Customer]) FROM [tblMain];
But when i use this i get
Syntax error (missing operator) in query expression 'Count(Distinct Customer)'.
I have tried leaving out the square brackets but this does not work....

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".

I tend to work with large amounts of data (extracts from company systems) and I create a lot of Access/VBA based tools to automate processes.
I have an annoying error which has always appeared but I don't understand the root cause of it.
When viewing a query, if I filter, I get an error message pop up (though after clicking through the error I can still use the filter function):
"syntax error missing operator in expression 'name of field'".
This seems to happen when I add several calculated fields. Here are some examples of the conditions and calculated field formulas I'm using in this current one:
Conditions:
<>"CINEMATIC" And <>"SFX"
Not Like "*_ZZ*" And Not Like "*test*" And Not Like "EP_*"
[Forms]![FRMscriptPrintReview]![selectLangCombo]
Calculated Field:
Audio Ref Guide: IIf(Left$(Right$([TBLdata]![Script Resource],2),1)<>"_","?",Right$([TBLdata]![Script Resource],2))
I get the impression that its more of a bug with Access as the formulas aren't complicated really but need confirmation on this and if there is a way I can avoid it.

I have a database that is used to create Quotations. After all of the information is entered the queries that hold the calculations must be run. I have lots of calculated that rely on other calculated fields. When I need to Sum all of the calculated fields in one field I must create a new query. I currently have a QuotationID, PartID, and MetalID all linked together. The first of the calculations are done per Metal, and these are working fine. I run into a problem when the calculations need to be done by part. My Queries are creating a record for every Metal and this is throwing all of my numbers off.
