Queries :: Find Latest Date In A Table Where Dates Are In 2 Separate Columns And Multiple Rows
May 19, 2015
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)
Below is the code I have for a query. This query shows Processes, Operations, etc. Due to multiple Effective_ (Effective_ stands for Date) The Operations show multiple times. What I would like to do is have each Operation show only one time based on the latest Effective_ i.e. If Operation START-UP is listed three times due to three effective dates 2007-01-04, 2007-01-08 & 2007-01-17 I would only like to the the one associated with the 2007-01-17. Is there a way to accomplish this in my query?
SELECT ASSYROP.PROCESS, ASSYROP.OPERATION, ASSYROP.OPERATION_, ASSYWC1.PROCESS_AT, ASSYROP.OPERATIO_1, ASSYROP.EFFECTIVE_ FROM ASSYROP INNER JOIN ASSYWC1 ON ASSYROP.OPERATION = ASSYWC1.OPERATION GROUP BY ASSYROP.PROCESS, ASSYROP.OPERATION, ASSYROP.OPERATION_, ASSYWC1.PROCESS_AT, ASSYROP.OPERATIO_1, ASSYROP.EFFECTIVE_ ORDER BY ASSYROP.PROCESS, ASSYROP.OPERATION, ASSYROP.EFFECTIVE_;
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.
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:
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 query which is used to pull data from 2 tables.
1. Only show the records that have 2 or more same Pat#, FName and LName. If it is a single record I would like to hide it.
2. Need to see the different dates amd know the difference.
Currently Query Looks like this.
Pat# FName LName Reason Status Date 00001 John Doe 1 1 11/13/2014 00002 Sally Doe 2 1 11/25/2014 00003 Bill Bates 1 1 11/04/2014 00003 Bill Bates 2 1 11/07/2014 00004 Jenny West 1 1 04/03/2014 00004 Jenny West 2 1 04/10/2014
The Signup reason number 1 represents the signup date and number 2 represents the time they left. SignupStatus number 1 represents a group.
So I am hoping my end goal it would look something like this.
Pat# FName LName Date 1 Date 2 Difference 00003 Bill Bates 11/04/2014 11/07/2014 3 Days 00004 Jenny West 04/03/2014 04/10/2014 7 days
I am trying to avoid using VBA or SQL. I do not know where to input it.
I tried to use the “Find Duplicates” query wizard but this did not work because it finds duplicates like last name first name, but it does not separate the dates.
I have 1 table that I duplicated to make 3 tables total. I did this b/c I am trying to create separate columns from the same field and table. The field is Workorder. Each workorder list the workorder number followed by a dash and then code. I am wanting to put all of the workorders with the same code in it's own column.
I have 5 codes that i am searching for. The first column list the workorder and a code (123456789-AD). The second column (123456789-BC). I'm good to this point but my problem occurs next.
The third column i am trying to put 3 types of workorder and it's code in the same column. As follows, (123456789-CD, 123456789-TC, and 123456789-PTC. However, when I do this it takes the results from the 3rd column and applies it to the 3rd column but also the 1st and 2nd column. I tried a UNION query and unless I am doing it incorrectly it does not work.
I have a database with a form that has 3 fields in a subform. I need to paste there data from multi rows. Now I have to do this column by column and paying attention that I select them correctly. Is there a way to directly insert the data by selecting only 1 field and have the data directly there as it would in excel?
Now we use excel as a "between" road to paste it there and then copy it from excel and paste it into access.
I have a database with all the hours employees have logged stored in the database. Our payroll company wants an excel spreadsheet that has very specific info in particular columns and fields on the excel spreadsheet, so I'm trying to design a query which will put the correct info in the correct fields per their system.
The challenge is, I have currently a query with Employee ID, Overtime Hours, and Regular Hours as separate columns.
I need to translate this to a query with a single column for hours and a separate column that designates those hours as OT or Reg, with two rows for those employees who have both types.
I don't know how to create a query or a formula in a query to break out each employee row into multiple rows with different data in the hours column. It seems like there's something pretty straightforward that I've done in a similar vein but it doesn't seem to work - I can do the opposite and combine those hours by using the SUM function in a query, but I can't seem to break it out this way.
Ive been converting .xls files to Access database files. I would like to use ACCESS to develop the Reports but the client wants the Reports to look like those in EXCEL..eg. where you have lines between rows and columns. If I could give my Access Reports the same look and feel, I could wean these guys off of Excel and into the wonderful world of relational models.
Does anyone have sqlcode or tricks I might use to create the Excel 'look alike' report in Access?
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'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
How do you return the most recent date of multiple columns.
I have a table (tbl_courses) that has a list of training courses. We want to know when a client completed the course most recently.
The problem is, for one course there has been up to 4/5 different variations of the course with different names over the years. E.g. "Drug awareness" has also been known as "Drug Aware" "Illegal Substances" and "Stoppers". I want to pull through the most recent date for all of the above.
We have a field in the Courses table that links the courses into groups (e.g. All drug aware courses come under "23"). Not sure if that works?
Is there a way to do this? The Tbl_Courses is linked to Tbl_Clients via a ClientID.
I've managed to do it in SQL using GREATEST() but that isn't an option in Access.
I have an database that uses a couple of different date ranges, so I created a table that shows the different date ranges that may be required (xReport Dates) so I didn't have to keep manually editing queries or entering dates every time.
I have one query that appends data from one table into another based on a date range that you need to manually enter when prompted; I can't seem to get it to refer to my xReport Dates table for the range.
I have 3 queries named Mech Final Equipment 3 Mth, Mech Final Equipment 6 Mth, and Mech Historical Final Equipment.They all have two fields-Final equipment and Sum of Sum of Down (calculating the number of minutes each piece of equipment was down in the time period selected).
My ultimate goal is to join the three queries to display a pivot chart that uses the Final Equipment as the category field and 3 Mth, 6Mth, and Historical as seperate data fields.What I have is a join query (Which I have named Mech Final Equipment H63 Joined)
Using this SQL:
Code:
SELECT DISTINCTROW [Mech Final Equipment 3 Mth].[Final Equipment], Sum([Mech Final Equipment 3 Mth].[Sum Of Down]) AS Duration FROM [Mech Final Equipment 3 Mth] GROUP BY [Mech Final Equipment 3 Mth].[Final Equipment] UNION
[code]...
Which returns a table that looks like this:
Final Equipment, Duration
Ancillary Equipment, 225 Ancillary Equipment, 401 Ancillary Equipment, 1787 Brush Unit , 1252 Brush Unit , 2519 Brush Unit , 8004
And so on.What I need the table to look like is this
Final Equipment, 3 Mth, 6 Mth, Historical
Ancillary Equipment, 225, 401, 1787 Brush Unit, 1252, 2519, 8004
And so on, like a cross tab.I tried to do a crosstab query but I don't have enough fields.
I have been given the task of organising a mail-merge with a sharepoint list, but the names and emails attached to each object are seperated by a delimiter. Furthermore each person is associated with many objects, and they want the merge programmed to only send 1 email to each person.
So what I need to do is split the data in one column into three separate columns, and then perform a concatenate. The concatenate isn't an issue, but how to split the data into 3 new columns within Access?
If worst comes to worst I'll tell them they will have to use the text-to-columns function in excel first, but would like to try and avoid that where possible.
And I'd like to convert it to this: Member_IDDiagnosis - 1Diagnosis - 2Diagnosis - 3Diagnosis - 4 10000 HypothermiaFrost Bite 10001 Fatigue DehydrationExhaustion 99999 Exhaustion Hypothermia
The columns don't line up well but I am looking for each diagnosis to move into one of the 4 columns, depending on whether it is the first, second, third or fourth diagnosis associated with the member.
I am trying to create a database for a clinic, and am severely stuck on how to input appointment dates for individual patients.
I have been using the 'student' database from office.com as a template for how to save the dates (given that appointments and attendance are exactly the same!), however, even after following what has been set up in the 'student' template database, I can't seem to replicate it.
Every time I add multiple visit dates for a specific patient, these exact dates show up for every other patient in the database. I need to be able to add different dates for all the different patients.
I'm trying to create a query that has a calculated field that shows a maximum value from multiple fields.
As far as I can find, this is not built into Access, so I've used this code from a Microsoft page:
Code: Function Maximum(ParamArray FieldArray() As Variant) ' Declare the two local variables. Dim I As Integer Dim currentVal As Variant ' Set the variable currentVal equal to the array of values.
[code]....
The problem I'm having is, well this doesn't work for me.I'm a bit of an beginner VBA coder, but I understand this code and don't know why it won't work.It only displays the value from the field within the brackets.The values used are Dates, so I need to display the latest date from multiple fields.
I have a Microsoft Access table with the following columns: A,B,C,D,E,F. In first row of Column A, I have the following string value: "Al,Peggy,Kelly,Bud,Buck" What I would like to do is parse this string as such:
