Queries :: Select Last Input From Several Date Columns
Oct 2, 2013
Having built a database that tracks projects across their lives, I've now been asked it I can identify the latest status of the project in a "quick view"
The table "All Projects" has columns that list the Project Number; Project Title; Project Manager and further colunms that list dates that the various stages of the project were achieved. i.e. Start Date; Date Milestone 1 Completed; Date Milestone 2 completed etc.
The projects are such that Milestone 5 may be completed before Milestone 2 and so on, so I need to be able to identify which Milestone was the last to be completed.
I thought of trying an IIF but the progress across the Milestones isn't logical so it won't work. I found something on the Internet about "Greatest" being used on some other program (not Access), which Access didn't like at all!
If the requirement had been given before starting building the db, I would have done everything differently, but I have no real desire to go back to stage 1 and start again, so how or if it's possible to find the highest / latest date relevant to the Project Number across the row of data ?
I have a database table in which I'm trying to pull sales data and generate sales reports from. The problem I face is that the sales data is recorded into a table with this structure:
Year | Customer | Sales_Month_1 | Sales_Month_2 | Sales_Month_3
Rather than having a single field "Month" in which I could set criteria or prompt the user to select a month to derive sales data from, I need to write a query that through user input (or through some code within the query) the right field will be selected. An example of this would be generating a report for the 1st month of the year, obviously.
I have a database that tracks students and their test scores. I am trying to figure out a way to where it will pull the student's latest test score and compare it to see if they fall within standards. So far I have 3 tables.
The query I have written looks like this: SELECT tblStudents.studentID, Max(tblResults.resultDate) FROM tblStudents LEFT JOIN tblResults ON tblStudents.studentID = tblResults.resultStudent GROUP BY tblStudents.studentID." The data pulls just fine at this point. What I'm trying to figure out is how to then add more columns to this query to start doing comparisons. When I try to add more columns it tries to use them for additional grouping and adds many more records.
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 a large database filled with customer records. Some customers come one time. Other customers come 50 times at year. I want to find all customers that have records that are less than 30 days apart so I can ultimately see the types of products they buy. How do I write the query?
I attached a picture of a sample database. The 30 day (+/-) field doesn't exist but I would like the query results to build it.
I'm using a form to select a date range. Using the following, and entering start date of 6/1/14 and end date of 7/1/14 I would expect to pull the records with a date of 7/1/14; however it doesn't. I have to enter and end date of 7/2/14 to pull 7/1/14 records.
>=[Forms]![F_Transaction_Date_Range]![txtStartDate] And <=[Forms]![F_Transaction_Date_Range]![txtEndDate]
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 need to find the frequency of client's appointment activity after their last appointment in a 4 month window.
My question is: (1) Is my SQL going to give me the last time a client was in the office within the 4 month window?
(2) What will my SQL need to like to count frequency of appointments before and after window for each client?
(3) Can I do (2) in the same SQL shown above or will I need to make a new SQL statement?
Code: SELECT tblTest.Client, Last(tblTest.AppointmentDate) AS LastOfAppointmentDate INTO tblTest FROM tblTest GROUP BY tblTest.Client HAVING (((Last(tblTest.AppointmentDate))<#4/30/2014#)) ORDER BY Last(tblTest.AppointmentDate);
Details
Date Window I need to select the clients last appointment: Jan 1, 2014 - April 30, 201
Once the last appointment has been determined for each client in that window I need to count the frequency of appointments before and after that date.
get the data from two tables on the basis of criteria...
I want to select the whole table1 which has 6 fields including Emp_id...
I want to select the single field from table2. field name is "Username" from second table2. will select the username on the basis of Emp_ID becaue both tables has same emp_ID.
It should be in order like. Emp id, Username, Startdate, Enddate, Hours, trainingNames.....
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'm developing a small Access 2007 database. I am looking for a dropdown list for one of the columns that would automatically reflect the contents of the previous 4 columns of the same row.
Sample table mentioned below. Column 6 (Winner) should be a dropdown reflecting the nominations1,2,3
Zone Nomination 1 Nomination 2 Nomination 3 Nomination 4 Winner

I have a MS ACCESS 2010 database with a data table which i am trying to create a query from. I have 6 columns of data( one with an ID Field and 5 Name Fields). Below i have made examples of how it first appears as a simple query and the second will show you what i would like it to look like.
What the simple query looks like: [URL] ...
Second what I want the query to look like: [URL] ....
Hi! I want to add two columns a and b. However, there are rows in which EITHER a OR b is NULL. This should be handled as if the cell would be zero. Is there any way besides filling in 0s in the tables?
I tried SELECT a, b, IIF( a = NULL, b, IIF(b = NULL, a, a+b)) AS c FROM
I'm fairly new to Access. 's various select queries containing useful and useless results. I want to create a select query that will pick out all the useful figures into a 1 row table that can then be pasted into Excel.
e.g Existing Select Query 1 returns 1 row showing Average Age, Average Price, Total rainfall Existing Select Query 2 returns 1 row showing Average Weight, Average Salary, Total snowfall Existing Select Query 3 returns *2* rows: It returns Distance from London, Hours daylight and population for Town A and Town B
I want a select query that returns 1 row showing (6 items):
Total rainfall, Total snowfall, Town A Distance from London, Town A Population, Town B Distance from London, Town B Population.
I've been able to handle getting Total rainfall and Total snowfall. But I cant figure out how to get Town A Distance from London, Town A Population, Town B Distance from London, Town B Population to appear in the same row of the same query results as Total rainfall, Total snowfall.
I am trying to write a query that will select distinct values from three columns. The table name is Hoods. The columns are C1, C2, and C3. All three columns contain colors and can have the same values, but I only need to have a particular color selected once. For instance, all three columns contain "Black", but "Black" should only be listed once. The result of the query will be used in a drop down list.
The following works for one column:
SELECT DISTINCT [Hoods].[C1] FROM Hoods WHERE C1<>"";
I can create a customized Input Mask, however there are two possible structures that the data may take. I think that this should be doable by the use of two fields, if it can be done with one field it would be preferable for searching options. If I have to use two fields there would only be one or the other used for each record so I would prefer to have the unused field inhibited. Either way the code work is beyond my present ability, any assistance would be appreciated.
The columns are PayPeriod, StartDate, EndDate, FiscalYear
What I want to be able to do is highlight a chunk of dates and have the first selected StartDate and the last selected EndDate populate two hidden text boxes so I can use them for my queries/reports.
I've tried a couple different ways. Each time what happens is it only uses the last item I have selected in it's calculations.
Code: Dim ItemIndex As Variant For Each ItemIndex In Me.lstPayPeriods.ItemsSelected If Me.lstPayPeriods.Selected(ItemIndex) And Me.lstPayPeriods.Selected(ItemIndex - 1) = False Then Date1.SetFocus Date1.Text = Me.lstPayPeriods.Column(2, Me.lstPayPeriods.ListIndex) End If Next
In this example I tried to have it go through each Item of the listbox. I wanted to check to see if the current row was selected and the row before it wasn't. That way I could determine it was the first item selected in the group of selected items. It would always only use the last item I had selected.
Code: Dim CurrentRow As Integer Dim FirstDate As Date For CurrentRow = 0 To Me.lstPayPeriods.ListCount - 1 If Me.lstPayPeriods.Selected(CurrentRow) Then Date2.SetFocus
[Code] ....
I tried to do something similar with this code. Again, it only uses the last item I have selected.
I am not a professional programer but would like to do a simple database for my group to track research progress. Is that possible to "pick up a date from drop down calendar" then the date will input to the cell (save in table) in a form, instead of typing it in? I saw that in lots of web sites, but can not figure it out how to do it in Access. Tried "Canendar Contol" and "LANDesk Data control" in the toolbox.
Is it possible to select 1 MAX date from multiple date fields for a record?
For example, on an employee record there are 10 date fields, each for a performance review date. Some employees may have date fields 1-3 with values, some with just 1, others 1-5, etc.....depending on how many performance reviews they've had.
Is there a way to pull the MAX review date for an employee, knowing that the MAX date could reside in Field 1 for a certain employee, and could be from Field 7 for another?
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 am trying to add calculations to queries based on columns in the query... it seems to randomly expect 'Expression' or 'Group by' as column types, and Im having to create 3 sets of queries following on from each other to de-dupe data and allow filters on calculated values.
Also I've got a function which turns a date into a quarterly cohort, e.g. Oct 2013 -> 20134. I use ot on a lot of dates. I created a VBA function, CohortQ used as follows in queries:
Code: Function CohortQ(InputDate As Date) As Integer If InputDate = 0 Then CohortQ = 0 Exit Function End If
[Code] .....
But when I run it on a date field, it gives me a data mismatch error. I can't step through as it's working on 600K rows. If I put the function into the query,
Dear fellow forum members have been trawling the forum but unable to solve what seems a simple issue.Have a form with a field for a short date input.I would like the year to be input automatically and the user to be left to input day and month.Have played around with format(date(),mm-yy) but unable to crack it.If someone can save me another sleepless night I would be more than grateful.
