but the tricky part is the number could be suffixed with a revision. It is the latest revision I would like to find. For example, If I have a number followed by 3 revisions I would have:
I would like to write a ms-sql query to return the records of each customer number with the latest OrderDate. One more thing, if the customer has two separate order numbers on the same date(should be the latest date), the query should be able to pull up both the records.
I tried with the code below but its taking a long time to execute and finally hanging up MS ACCESS.
SELECT * FROM TableName AS a WHERE Not Exists (SELECT * FROM TableName b WHERE b.CUSTNo = a.CUSTNo AND b.OrderDate >= a.OrderDate);
I have two tables. The first is called Drawing Register and contains the fields Drawing No (primary field) and Drawing Title.The second table is the Drawing Register Details table which contains the fields Drawing No (joined field - Drawing Register table), Revision, Revision Notes, Date Issued.
I have a query and report which will list all the revisions for each drawing. This is very important and useful. However I want a summary report which will only show the last revision for each drawing.
I copied the original query, turned on the Totals option and under the Date Issued field changed Group by to Max. However it is still returning all results for each drawing instead of only the last issue date for each drawing.
FName | END_Date| --------|---------------| John| Oct 09, 2014| John| Oct 15, 2014| John| Oct 25, 2014| Mike| Dec 10, 2014| Mike| Dec 15, 2014| Mike| Dec 20, 2014| Mike| Dec 25, 2014| Jimm| Dec 10, 2014| Jimm| Dec 15, 2014| Jimm| Dec 20, 2014| Alex| Dec 01, 2014| Alex| Dec 05, 2014| Alex| Dec 10, 2014| Thom| Nov 10, 2014| Thom| Oct 10, 2014| Thom| Aug 10, 2014|
The output will be:
FName | END_Date| ----------|---------------|
John| Oct 25, 2014| Mike| Dec 25, 2014| Jimm| Dec 20, 2014| Alex| Dec 10, 2014| Thom| Nov 10, 2014|
The query table(output) will just have to be latest date("END_Date") per "FName"
I have a table of accounts and a table of rates. There is a one-to-many relationship between them (i.e. each account can have multiple rates, each with their own - unique - effective date)
I'm trying to build a query which will show me all of the accounts in the accounts table and the most recent rate (based on the effective date) for each of those accounts.
This is as far as I've gotten with the SQL :
Code: SELECT [tblAccounts].[AccountID], [tblAccounts].[AccountNumber], [tblAccounts].[AccountName], [LatestRate].[IntRate], [LatestRate].[EffectiveDate] FROM [tblAccounts] LEFT JOIN (SELECT TOP 1 [tblRates].[AccountID], [tblRates].[IntRate], [tblRates].[EffectiveDate] FROM [tblRates] ORDER BY [tblRates].[EffectiveDate] DESC) AS LatestRate ON [tblAccounts].[AccountID] = [LatestRate].[AccountID]
But this can't work because the [LatestRate] subquery can only ever return one record (i.e. the most recent rate across all of the accounts)
I need the most recent rate for each of the accounts in the main query
(FYI - I use an outer join as it is possible for no rate to be available in the rates table for a given account, in which case I want to return the null value rather than omit the account from the resulting dataset...)
I have a database that is used (partially) to enter appointments during a day. In the appointment column I've entered the date and time as dd-mmm-yyy-hh-nn-ss. I'm now trying to search for appointments entered on a specific day through a user input ([Enter Date] in the query criteria) Problem is, this only returns records where the time hasn't been entered and the time shows as 00:00:00.
I've tried CDate which gives me add/mmm/yyy return. if I try to search against that I get nil returns though. As a test I put DATE() in the criteria but it then says that it's an invalid foremat. I've also tried various machinations of "Like" and "Between" without success.
How to find the max value of a field in a query... How does a query display the max record based on the primary key... want to isolate the last record created, the one with the max primary key.
I have a table of SOPs/WIs. Each, with time, gets a new version - this I keep in the child table.
tblVersions ------------ VersionID (PK) SOPID(FK) Version (integer) IssueDate (date)
I want to make a list of the currently valid versions, i.e. for each SOPID pick the VersionID with the latest date.
One can do many things with subqueries and Max - functions, but after some experimentation I have stumbled upon this:
Code: SELECT Last(tblTest.VersionID) AS LastOfVersionID FROM tblTest WHERE (((tblTest.IssueDate)<Date()-10)) GROUP BY tblTest.SOPID;
The function Last has a bit tricky reputation and description on the web. It does yields the right result in my testcase though , see the attached db - run query3.
Query3
Code: LastOfVersionID 100 90 20 40 666 888 55 8
Update: Well, it isn't. Just changing the VersionID numbers to something other than an ascending sequence renders an incorrect result with the above query. So what is the best way to get the desired result? (Access 2007)
I'm having trouble with a simple query. They have an access database with a table like this (simplified for this example):
-------------------------------- Name Result Date -------------------------------- Bob 5 1/1/2014 Bob 6 2/2/2014* Bob 7 3/3/2015 Bob 8 5/4/2015* Len 5 1/1/2014 Len 6 2/2/2014* Len 7 3/3/2015 Len 5 7/4/2015* ---------------------------------
how I would write a query that gives me the latest result that each person earned in each year (I put a * symbol against the rows above that I am talking about)?
Bob 6 2/2/2014 Bob 8 5/4/2015 Len 6 2/2/2014 Len 5 7/4/2015
(The database is normalised and this table has an ID field).
I have a query with a record id, report date and status.
How do I pull the latest record if the status is AA?
For latest record in report date I used Max in Totals. With just this max it is pulling the latest date for each set of records with the same record id.
This is a start now how do i pull the latest record that has a AA status?
I have a list of project, each of which have dates which work were carried out on them. Each project can have more than one date. I want to be able to find the last date that any work was carried out, and then calculate how many days have passed since that happened.
(1) a query that returns the latest record (newest) in a table called 'Invoices' and then
(2) places this value in a form called 'FrmInputInvoices' as the default value when the form opens. Newest record is by Autonumber and the table defaults this to top of table as views newest down to oldest.
Re (1) Query is called 'QInvoices'; the values I want to return in my query is ID (my autonumber) and Invoice_No . Must be a simple answer to put in the criteria, but I can't find this.
Re(2) What code do I use in my Form field named 'Invoice_No when the curser defaults there on opening?
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 table that contains readings from several pieces of equipment as well as the status of each one. Each record has a timestamp, equipment number, status, etc. What I want is to create a query that will return the latest record for each equipment number. Simplified example table:
There are more than 20 different Equipment numbers and they are read several times per day and sometimes some of them get missed. What I'm looking for is a way to get a list of all the machines with their latest reading so they can tell which machines are running and which are down based on the last time they were read (instead of specifying a date). I can get this for one machine with no problem. I'm having trouble getting it for more than one machine. I tried a union query (with just 2 of the machines included for testing) but it only returns the results from one machine:
Code:
SELECT TOP 1 TestCompressorRoundQuery.LoggedAt, TestCompressorRoundQuery.AssetNumber, TestCompressorRoundQuery.CompressorID, TestCompressorRoundQuery.Status, TestCompressorRoundQuery.CompressorIntegrity, TestCompressorRoundQuery.Notes FROM TestCompressorRoundQuery WHERE (((TestCompressorRoundQuery.AssetNumber)="104399")) UNION ALL
[Code] ....
I'd rather not have to create a seperate query for each machine and then join all of those together! I think perhaps a Union query might not be the correct approach. All the data is coming from only one table.
If I have four date Fields in a query, Astart, Bstart, Cstart, and Dstart and want to have a calculated field to find the latest date for each record how would I do that? I have tried things like:
I have a list of archive folders with unquie IDs and images files which have a version history.
I need to remove the history and just keep the latest archive version set of files. It seems an append query would be best but just can't think the best way todo it.
In the above example I only want to keep user 8769091 latest filename info from archive 3 and exclude the rest. I need todo this for over 3000 users who could have multiple versions.
How do I make an append query only append the records beginning with the next autonumber?
I have linked tables in db...one db is for warehouse employees to input their orders and the other table is in the original db for managers to use for reports. I need to append the records to original db throughout the day, but the records cannot be deleted from warehouse db because it keeps running total of order minutes (for production purposes) so employees know how many minutes they have (and need to make up) through the day. Also, managers need up to date db so they can see if they are on track.
The autonumber field is my primary key.. I hope this all makes sense.
I am working on a report and I am stuck with the following problem:
Here at work we use two tables. One for creating records and for the updates of the created records. In the attachment you see a part of the table 'updated'. What you see is one ServiceNumber (1-551747091) which is changed users (Eigenaar.) three times.
I want to query the latest user of each ServiceNumber. So that the result is:
ServiceNumber | User 1-551747091 | MKB_VERHUIZEN etc.
I have 2 tables... 1 is customer info (name, address, etc...), and the second is shipments (ShipToCustomerName, ShipmentDate, etc...).
Now, I wish to query the shipments table to get ONLY the LATEST shipment information for EACH customer.
If customer A has a shipment in Jan 1, Feb 2, and March 3... while customer B has a shipment in April 4 and May 5. then the result of the query should be
customer A - March 3 customer B - May 5
Is there a simple way to construct such a query?!?
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 two fields. A barcode field will have several instances of the same data, and the other field has different dates and times when it was scanned. I need to be able to query the barcode field and only return the record with the latest time. Can this be done in a query or do I need to do something else? Here is a sample of data I am working with. I attached a small sample of data as an example.
I'm fairly new to SQL and have a problem finding the latest record.
Lets say I have a development project that has many disbursal payments to be sent. I want to find the latest disbursal record created for that one project instead of having all of the disbursal records show on the query.
I'm trying to work out how to do this in a query but haven't got a clue where to start.
Please, if anyone can help I'd be very grateful!:D
I am trying to pick the latest record from "tblEmpVac.id" field but I keep getting syntax errors. I am thinking if the "tblEmpVac.id" = Count('tblEmpVac.id') then that will show the most current record as it will count and match the last record correct?
Another problem is if I put it into the WHERE section, it will give a conflict. So I don't know where to put it. Below is the SQL, if anyone can help it would be great.
SELECT DISTINCTROW tblEmp.position, tblEmp.fname, tblEmp.lname, tblEmpWorkHistory.region, tblEmpWorkHistory.[current store], tblEmpVac.current_year, tblEmpVac.id, tblEmpVac.entitlement, tblEmpVac.days_taken, tblEmpVac.days_carryover, [days_carryover]+[entitlement]-[days_taken] AS total FROM ((tblEmp INNER JOIN tblEmpVac ON tblEmp.ssn = tblEmpVac.ssn) INNER JOIN tblEmpWorkHistory ON tblEmp.ssn = tblEmpWorkHistory.ssn) INNER JOIN tblEmpWorkHistoryData ON tblEmpWorkHistory.ewh_id = tblEmpWorkHistoryData.ewh_id WHERE (((tblEmp.position)<>"Terminated") AND ((tblEmpVac.current_year)="2005")) ORDER BY tblEmp.position, tblEmpWorkHistory.region, tblEmpVac.id;
