Queries :: Find Dates In One Table But Not Another
Mar 14, 2014
I've got two tables, both are indexed by customer ID, with a series of dates against the customer ID. One has a list of all dates a customer was visited, the other is a list of dates where activity happened on the customer account
I want to get a list of the dates when the customer was visited but where no activity happened on the customer account, i.e. where there is a customer visit date on the customer visit table but no record for that date on the activity table.
How do I do that? I can find all dates where was a date was on both tables, but how to find where its on one but not the other
I am trying to find the latest date in a table where the dates are in 2 separate columns and multiple rows. (there are business reasons why there are 2 dates per row they represent different but comparable activities)
I have a table "Assessment tracker" with the following structure
Name Type Candidate short text Unit short text EV1 Date Date EV2 Date Date
My Data:
Candidate Unit EV1Date EV2 Date TH1 10 07/05/2015 25/05/15 TH1 10 07/05/2015 07/06/15
I have a query "Candidate AC Dates" that compares the 2 dates EV1 and EV2 and outputs a 3rd column with the latest date.
It does this by using a function shamelessly copied from the web somewhere...
Function Maxdate(ParamArray FieldArray() As Variant) ' Declare the two local variables. Dim I As Integer Dim currentVal As Date' Set the variable currentVal equal to the array of values. currentVal = FieldArray(0) ' Cycle through each value from the row to find the largest.
[Code]....
This is working well (I think)
I then want to find the latest date for the 2 records i.e. the Max value for the Achdate.
Query: SELECT [Candidate AC Dates].Candidate AS Expr1, [Candidate AC Dates].Unit AS Expr2, Max([Candidate AC Dates].Achdate) AS MaxOfAchdate FROM [Candidate AC Dates] GROUP BY [Candidate AC Dates].Candidate, [Candidate AC Dates].Unit ORDER BY [Candidate AC Dates].Candidate, [Candidate AC Dates].Unit, Max([Candidate AC Dates].Achdate) DESC;
But this is returning
Candidate Unit MaxOfAchdate TH1 1025/05/2015
I expect it to return
Candidate UnitMaxOfAchdate TH1 10 07/06/2015
It looks to me like MAX is considering only the day value rather than the whole date. I suspect this is because it is considering the results of the function in the first query as a short text rather than a date field. (I've tried to force this through declaring the variables as dates but don't know where else to force this. (I am UK based hence the DD/MM/YYYY format)
I have been working on a simple data base for some time now (beginner level) and am still trying to improve it. I would like to do something but before that I would like to have your opinion to know if it is even possible?I have a query QryMainReport:
Start Date/Time End Date/Time Employee
At the moment this is what the format of my report looks like (I removed other unnecessary fields):
StartTime----------EndTime---------------Employee 12/06/2014 01:00--12/06/2014 03:00------John Smith 12/06/2014 04:00--12/06/2014 06:00------Jane Doe 13/06/2014 02:00--13/06/2014 05:00------John Smith 13/06/2014 08:00--13/06/2014 08:00------Jane Doe
I would like to do as a report. (Dates would always be from Sunday to Saturday). I am not sure it is possible to do that. I suppose first it would mean:I would have to do a query to separate the times from the dates?I would have to find a way for Access to find the unique dates and unique names?Does it mean I have to use cross tab queries?
Code: tblPrice PosNr PriceDate Company Price 1 01.01.2014 Firma A 5 2 02.01.2014 Firma A 7 3 03.01.2014 Firma A 9 4 04.01.2014 Firma A 8 5 06.01.2014 Firma A 6 6 02.01.2014 Firma XY 11 7 03.01.2014 Firma XY 9 8 04.01.2014 Firma XY 7 9 05.01.2014 Firma XY 8 10 06.01.2014 Firma XY 10
And I have a table with the dates, for which I need a price.
Code: tblDates PosNr PriceDate Company 1 01.01.2014 Firma A 2 02.01.2014 Firma A 3 03.01.2014 Firma A 4 04.01.2014 Firma A 5 05.01.2014 Firma A (no price available) 6 06.01.2014 Firma A 7 02.01.2014 Firma XY 8 03.01.2014 Firma XY 9 04.01.2014 Firma XY 10 05.01.2014 Firma XY 11 06.01.2014 Firma XY
And now I want to combine this tables, and for the dates which have no price, the last price should be taken.
Code: tblResult PosNr PriceDate Company Price 1 01.01.2014 Firma A 5 2 02.01.2014 Firma A 7 3 03.01.2014 Firma A 9 4 04.01.2014 Firma A 8 5 05.01.2014 Firma A 8 (actualy no priceavailable, so take last price) 6 06.01.2014 Firma A 6 7 02.01.2014 Firma XY 11 8 03.01.2014 Firma XY 9 9 04.01.2014 Firma XY 7 10 05.01.2014 Firma XY 8 11 06.01.2014 Firma XY 10
how I can get this?
I have this code, but it need hours.
Code: SELECT tblDates.PosNr, tblDates.Company, tblDates.PriceDate, (SELECT TOP 1 B.Price FROM tblPrices As B WHERE B.Company = tblDates.Company AND B.PriceDate <= tblDates.PriceDate ORDER BY B.PriceDates DESC ) AS Price FROM tblPrices RIGHT JOIN tblDates ON (tblPrices.PriceDate = tblDates.PriceDates) AND (tblPrices.Company = tblDates.Company);
I know there is no more than 4 dups of each record.
what i want from this is a table that will give me a record of how many dups for each record then all the dates that they were added and the date between each record entry.
I have an "order details" table that needs to populate a field called "Voucher" with data from another table called "codes". The "codes" table also has a true/false field called "allocated" because once allocated the code cannot be re-used.
I am trying to work out how to automatically allocate the next unallocated code in the "codes" table to each record in the "order details" table when that order details record has a DiscountID of "92".
Order Details Table Fields and conditions/criteria: ID - primary key DiscountID - only when the DiscountID = 92 Voucher - only populated when Discount ID = 92
Codes table Fields and conditions/criteria: ID - primary key code = text field with a code like "einstein01", "einstein02" Allocated = False
Is there a way to put the next available code into the order details record then mark that code as allocated in the codes table. Then, move on to the next order details record that has a discountID = 92, input the next unallocated code and mark that code etc. etc.
Ideally, I would like to do this to happen via an event when the Order forms button "Close" is clicked.
I'm currently busy with something for my thesis as a student and I need to use Access for this. I'm not too new at access, I know how to do the very basics, let's say on the level of [if field contains *"text*", return x].
However I am struggling right now on something that shouldn't be too hard... I could do it immediately in Excel if there werent millions of rows..I have 2 tables. Table 1 regards a list of patent publication numbers (eg. WO2012024604A3) and additional data (publication date, title, etc), only the publication number matters for me now.
Now what I'd like to do is to create a third table which has for each of [Table 1].[Publication number]:
Column 2) A count of how many times the [Table 1].[Publication number] is found in [Table 2].[Cited Refs - Patent] ...
Column 3) In case a patent is cited more than once, return the [table 2].[publication Number Citing Patents] value of the earliest citing patent (so with the lowest Publication Date value).
For Column 2 I had expected it to be an easy count(iif( [Table 2].[Cited Refs - Patent] = "*"&[Table 1].[publication number]&"*")) command but apparently it's harder than that..
I've got 2 tables, same structure, one [T-temp-Target] holds number of training units split by module a trainee needs to finish the course, the other [T-temp-Actual] holds what they've completed so far.
Both tables have structure TRAINEEID MODCODE CountOfUnits
I'm trying to find the modules that they've not done yet so I can add up the units for them, only modules that have been started are recorded in the table of what they've done [T-temp-Actual], modules they haven't started yet aren't included in it. Here's the SQL
Code: SELECT [T-temp-Target].TRAINEEID, [T-temp-Target].MODCODE, [T-temp-Actual].MODCODE FROM [T-temp-Actual] INNER JOIN [T-temp-Target] ON ([T-temp-Actual].TRAINEEID = [T-temp-Target].TRAINEEID) AND ([T-temp-Actual].MODCODE = [T-temp-Target].MODCODE) WHERE ((([T-temp-Actual].MODCODE) Is Null));
I have a table where csv files get imported to on a daily basis. The key fields I am working with are a supply number and date. The problem I have is that sometimes the csv file will contain information that is correcting/updating information held in the table. This is creating duplicated records.I need to either create a query to find records that have the same supply number and date or find a way of overwriting the records in the table with the new data.
I have a report with 2 access tables (1 Master table and another a daily feed table)
The Master table keeps a log of all incoming records. (once append it to this table, should not show in future reporting)
The Daily feed information within the last 48 hours. (uploaded from an excel report into access temporary table)
When the daily feed table gets completed, I append the records and updated them into the Master to avoid duplication.
When I upload the daily feed table and I match it against the Master table to find duplicates, how can I delete the duplicates from the Daily Feed table?
This is my code to find duplicates:
SELECT CMPreport.ID, CMPreport.MbrName, tblMaster.ID FROM CMPreport LEFT JOIN tblMaster ON CMPreport.ID = tblMaster.ID WHERE (((tblMaster.ID) Is Not Null));
I have a table Billing_Temp that I need one field updated if I find a match in another table Random_Temp. I runt the query and it prompts for "Enter parameter value: Random_Temp.peopleID... what could be going on? Both tables have a field called peopleID and always Billing_temp has many more records than Random_temp:
UPDATE Billing_Temp SET Billing_Temp.audited = -1 WHERE (([Billing_Temp].[peopleID]=[Random_Temp].[peopleID]));
Setup a query to find the result in a table containing the highest date value.
The query is linked to two tables : Payment information containing the date, and tenant information containing the tenant.
In the query i have selected the tenant name from the payment table (which is linked to the tenant name in the payment table) and the payment terms - ie weekly / monthly etc. I've then selected the payment date from the payments table.
The query should return for each tenant the latest date they paid.
On the pay date i selected the Max option.
But it shows me more than one record.
SQL query is shown here
SELECT Max(tblPayments.DateDue) AS MaxOfDateDue, tblLease.cboPaymentTerms, IIf([cboPaymentTerms]=2,DateAdd("ww",1,[DateDue]),IIf([cboPaymentTerms]=3,DateAdd("ww",2,[DateDue]),IIf([cboPaymentTerms]=4,DateAdd("ww",4,[DateDue]),IIf([cboPaymentTerms]=1,DateAdd("m",1,[DateDue]),"n/a")))) AS calcNextPayDueDate, tblPayments.cboTenant FROM tblPayments INNER JOIN tblLease ON tblPayments.cboTenant = tblLease.cboTenant GROUP BY tblLease.cboPaymentTerms, IIf([cboPaymentTerms]=2,DateAdd("ww",1,[DateDue]),IIf([cboPaymentTerms]=3,DateAdd("ww",2,[DateDue]),IIf([cboPaymentTerms]=4,DateAdd("ww",4,[DateDue]),IIf([cboPaymentTerms]=1,DateAdd("m",1,[DateDue]),"n/a")))), tblPayments.cboTenant;
I have a table that is linked into access 2003. This table is updated by personnel in another location and I have to run a weekly report on engines that are below a certain performance level.
The column heading is MGT Margin and I have to list all of the engines that are below 20 degrees.
Can I run a query that looks at this table and produces a report of all the engines that are below 20 degrees?
I currently have to cut and paste each engine from the updated spread sheet every week onto a separate spread sheet and import that into access. If a query can be used to do what I am after I can use similar principles in other reports I have to run.
Giving up after a zillion tries. I have a table (tblLOADS) containing: BROKER, PUDATE, MATERIAL & DRIVER. I am able to create this query:
SELECT tblLOADS.L_ID, tblLOADS.BROKER, Max(tblLOADS.Pudate) AS MaxOfPudate, tblLOADS.Material, tblLOADS.Driver FROM tblLOADS GROUP BY tblLOADS.L_ID, tblLOADS.BROKER, tblLOADS.Material, tblLOADS.Driver HAVING (((Max(tblLOADS.Pudate))>0));
Problem: It's datasheet view displays all of the records for BROKERS, PUDATE, MATERIAL & DRIVER, instead of ONLY the records for the last PUDATE of each of the BROKERS, with their corresponding MATERIAL & DRIVER fields.
I have a parameter that I need to get a table contents between dates. In the query:
Birthdate: XXTable: criteria as follows: Between [Enter Start Date] and [Enter End Date:]
When run it gives me the Error - ! This expression is type incorrectly, or its too complex to be evaluated. For example, a numeric expression may contain too many complicated elements. Try simplifying the expression by assigning parts of the expression to variables
I have tried almost everything. The formatting of the Birthdate is x/x/xxxx or shortdate. Will this affect the input thus affecting the outcome of the query.
The database I'm working on is used for personnel budget projections. Because some employees are hired mid-year, I need to be able to use various dates in my projection calculations.
I have 3 different tables - one with the employee start date, the other with the fiscal year start date, and the last with the start date of certain special pay tables. In order for my projections to work correctly, I'll need to return in a query the minimum of these 3 dates. I know how to do a minimum value in a single field within a table, but don't know how to select a minimum from multiple values in multiple tables. Is this possible.:rolleyes:
Running Access 2010 and developed this query to filter out data from a table between times on 2 dates (day before report run and day of report). Covers data from a shift that carries over to the next day.Trouble is, the PC i developed on still operates the query as expected. However, on the PC the database resides (not networked just stored) and operates, the query brings up no data at all unless I remove the Time filtering.
This PC used to operate correctly up until early this year (about 18 months operated correctly) when the PC was replaced due to failure. Access version is the same and I am at wits end to what the cause is. Here is what my query looks like:
Quote:
SELECT Breakdowns.BreakdownDate, Breakdowns.Time, Breakdowns.Shift, Breakdowns.Downtime, Breakdowns.Equipment, Breakdowns.Conveyor, Breakdowns.Fault, Breakdowns.Stopper, Breakdowns.Gate, Breakdowns.Dolly, Breakdowns.Carrier, Breakdowns.FaultType, Breakdowns.Comments, Breakdowns.Tradesman FROM Breakdowns WHERE (((Breakdowns.BreakdownDate)=Date()) AND ((Breakdowns.Time) Between #00:00:00# And #6:29:00#) AND ((Breakdowns.Shift)="Night")) OR (((Breakdowns.BreakdownDate)=Date()-1) AND ((Breakdowns.Time) Between #22:30:00# And #23:59:00#) AND ((Breakdowns.Shift)="Night"));
I have a table which includes a start date field and completion date field for housebuilding.
I am trying to extract all records that have either a started date or a completed date between 2 dates supplied by the user. I have tried to use Between on both fields but that doesn't return results between the fields.
It workd if I just do it on EITHER the start date field OR the completion date field so that implies to me that I need to break it into 2 queries, one returning start date recrods and the other returning completion date records but then I would need to have somthing that removes records that appear in both the start date and the completion date results.
Is it possible to create a query to select all dates from a given reference date? I don't mean all dates in a table - I mean all dates generally?
(The idea being to fill the first field in the resultant dataset with the list of dates, then run subqueries off that to fill the remaining calculated fields)
I'm currently using a date field in one of my tables to populate this first field (the full SQL is in a separate thread here)
But that was just a convenient way of getting a list of dates; the dates in that table don't actually have any significance to the resulting dataset (other than they should roughly overlap with the dates I'm looking for)
The flaw in that method is that the table from which I get those dates can only ever have dates up to and including yesterday. I also need to get today's date in there (and calculate the subqueries based on that date as well).
It's also possible - although unlikely - that there could be random dates missing from that table as well - in which case I need to plug those gaps and calculate my fields for those missing dates as well.
For clarity; that first field (AsOfDate) should contain every weekday from the earliest date in that table (i.e. Min([tblBalances].[BalanceDate]) up to and including today. It doesn't matter if any of the dates inbetween are missing from tblBalances as the subqueries will just return zeroes for those dates (which is exactly what I want to see).
I have built a query to calculate the expiry dates of training courses but I am trying to input a criteria so that only dates within 90 days of todays date show. I am using Date()<90 but it doesn't return the correct information. What the criteria should be for this?
I have a table tROE with a field listing all dates starting 1/1/10 to date (populated), and three fields for currency exchange rates [USD], [RSD] & [EUR] which are empty and need to be populated. I have another table tROEPartial that has the exchange rates for some of the dates starting 1/1/10 but not all. Their structures are identical. I want to add the exchange rates from tROEPartial to tROE where the dates match, leaving the unmatched fields in tROE blank.
I have a table of records, which has within it two date fields (effectively, a 'start' and 'end' date for that particular record)
I now need to create a query to perform a calculation for each date between the 'start' date and the 'end' date
So the first step (as I see it anyway) is to try to create a query which will give me each date between the two reference dates, in the hope that I can then JOIN that onto another query to perform the necessary calculation for each of the returned dates.
Is there a way to do this?
So basically, if for a particular record, the 'start' date is 01-Apr-2015 and the 'end' date is 09-Apr-2015, can I produce a dataset of 9 records as follows :01-Apr-2015
(The *obvious* solution would be to create a separate table of dates, from which I could just SELECT DISTINCT <Date> Between #04/01/2015# And #04/09/2015# - but that seems like a dreadful waste of space, if that table is only required to generate the above? And it would have to cover all possible options; so it would either have to be massive, and contain every possible date - ever! - or maintained, adding new dates as necessary when they are required. Seems horribly inefficient!)
Is it possible to just select each date between the two reference dates? Or can you only query something which exists somewhere in a table?
And another table holding patient's surgeries (each patient will have only one surgery)
Code: PatientID SurgeryDate 1 4/1/12 2 ...
I need to compare these two tables and create a variable that indicates which pre-surgery visit date (i.e., VisitDate < SurgeryDate) is closest to the surgery date. In the above example, it would return:
