Select MAX Date From Multiple Date Fields?
Oct 20, 2005
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 appreciate the help guys!

I am currently building a booking and invoicing database for the small business where I work. One aspect of this database allows you to enter an employee name and schedule days off via a form I have already built. To access this information I would like a parameter query where you can enter a date once and then have this date looked up across a number of date fields. Here are my table column headings:
ID
Employee Name
Date 1
Date 2
Date 3
Date 4
Date 5
Date 6
Date 7
....etc
So, basically, the parameter query would ask "What date?" which the person would enter, and then search all 12 date fields to see if the date was contained in any one of them. Then it would pull any records which did have the date in one of the fields.
It seems really simple but I have searched and searched and can't seem to find the answer. Tried a multivalue field but does not seem to work.
Thanks very much, any help appreciated! Elspeth :confused:

I have a simple table in Access 2003:
Case# (numeric)
CaseOpen (Date)
CaseClose (Date)
Item# (numeric)
ItemOpen (Date)
ItemClose (Date)
Some of the date fields may be null; If null then that date may NOT be selected
I am trying to write a query that returns:
Case#
Item#
Only the most recent date in any of the four date fields
The heading that matches the selected date field
ie:
Case# = 251
Item# = 4756
Most Recent Date = 7/8/2005
Matching Heading = "ItemOpen"
I have been searching and reading for two days-
Help, please?
TIA

I'm trying to get my "IncidentDate" field to autopopulate two other date fields to a few days from the "IncidentDate". The other two date fields are "ContainDueDate" and "RootDueDate". I'm trying to accomplish this on my "Test CAP Form"
I tried using the following in the BeforeUpdate of "ContainDueDate" and received a complier error: expected =
Code : DateAdd(d,2,[IncidentDate])
so I removed the parenthesis and nothing happened
Code : DateAdd d,2,[IncidentDate]
I even tried redoing it in the AfterUpdate of "IncidentDate" and nothing happened either
Code : DateAdd d,2,[ContainDueDate]
I'm not sure if I'm even using the right function to get what I want.

Hi! My question is similar to Hondasteed earlier today but a little different. I have a database that has 6 date fields. I would like to develop a query where the user enters a start and end date and the query checks all six of those fields for the appropriate dates and shows only those records who have dates in that range. The dates would change each month as we ran the query again. I would appreciate any help as this has really had me stuck and I'm guessing it's a simple solution. Thanks!

I have a table where I use 3 date fields in, all with different views.
Field 1: Date as dd/mm/yyyy
Field 2: Quarter: q (shows the same date, but then as quarter of the year.
Field 3: Year: YYYY
Now I have a form that fills all of my fields, but is there a simple way () to populate the other two fields Quarter and Year from the value I entered in Date?
So if I change Field "Date", Fields "Quarter" and "Year" updates as well.
Maybe I don't need to do it in the form, but in the table?
I'm not that good with VB- scripts, and I'm not sure If it is possible to auto populate the table field Quarter and Year directly in the table itself.

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 am building Access (2013) database for 100+ employees to keep track of their expiry dates of visa/passport/work permits, for that to work I need to be able to search between date range to generate a report to work on. please check out the image attached as it will explain better where I am stuck, with current settings access keeps giving me empty query table as I think it searches for exact same result in all 3 fields at the same time. But I want it to search between all 3 fields and display if any of the 3 fields falls into that range.

automatically adding modified date/time to a record as it changes..I have a work log database for a team of people to keep track of workflow (documents in/out, stage in the workflow, owner of the record, etc.). I have a number of records that I want to automatically update a corresponding date/time field when it is changed. For example, one part of the workflow tracks a document through the approval of 5 different people. So I have a five records that are yes/no flags for approval and five records that are date/time for when it was approved. Right now my team is manually entering the five date/time stamps, but I'd like to have it automatically update when the check the "yes" box and update that field in the record.

I am trying to create an expression in a query to sum only the # of hours a student attended between two date fields. I do not want to use a parameter because each student has different start and midpoint dates and I need to see all of them in one list.These are the fields I'm using in the query:
Student Name
Start Date
Midpoint Date
Hours
It keeps giving me "0" or if I move the () around it says the correct syntax is [NOT]
Expr1: Sum([Hours]) between [Start Date] & [Midpoint]))

What I have: A table with multiple Date/Time columns. Here's an example:
What I would like: A month-by-month summary counting the number of entries in each of the three columns, like this:
I'm indifferent as to what happens with the months zeros across all three fields (whether they show up in the report with zeros or are omitted altogether).
Smaller Pieces: I am able to create such a summary for one column at a time:
Not what I'm looking for: I can not figure out how to create a query that does this for all three columns. My best attempt was a disaster:
I have attached the example file for your convenience: Database1.accdb
To clarify, my issue isn't the format of the date. I know about the Month(...) function. My question is regarding how to count this data and split it into a month-by-month summary (see the picture above in the "What I would like:" section)

I have developed a database which has required many checkbox fields to enable analysis. It requires to have the facility to input random/variable date ranges for statistical purposes.
I have built a query which obtains the counts of multiple fields using the following parameters in Query Builder in Access 2010. Although this comes up with the correct results for these multiple fields when I try introduce date range the results come up blank for all results.
An example of the parameters used for one of the checkbox fields in Query Builder is as follows:
Field: SumAnger: Sum([Anger]*-1)
Table: Default as only one table
Total: Expression
Show: Checked
This works fine.
My latest parameters for the date range are this:
Field: [cDate]
Table: Default as only one table
Total: WHERE Corrected! Whoops Copy & Paste Typo. Too early AM!
Show: Checked or Unchecked makes no difference
Criteria: Between [From Date:] And [To Date:]
This gives a statement in SQL view of:
SELECT Sum([Anger]*-1) AS SumAnger, Sum([Anxiety]*-1) AS SumAnxiety, Sum([Depression]*-1) AS SumDepression, Sum([Listening]*-1) AS SumListenig, Sum([Psychosis]*-1) AS SumPsychosis, Sum([Stress]*-1) AS SumStress, Sum([Other]*-1) AS SumOther, tblCommsLog.[cDate]
FROM tblCommsLog
WHERE (((tblCommsLog.[cDate]) Between [From Date:] And [To Date:]));
what I need to get this to work in Query Builder or failing that recommend some VBA script/code with embedded SQL to achieve the required report.

I am creating a repayment schedule (as a report) and I want to display a series of fields as a column which return (show) a date one month after the date in the field above.
The first repayment date field (Line 1) will show a date one month after the loan was paid out. the Next field below will show the date one month later.
I can't simply insert the "Date + 30" because that would get out of since over the year. If the loan was issued on say the 15th of January, I need the first field to display 15th February and the next would be .... 15th March.... Yes - You've got it!
Now I could do that in Excel, but I don't know how to get Access to do it.

Ok let me explainI have a list of 50 people who may have accessed events A,B,C at different times but what I want to do is to put a date in my form, run the quaery which will list all people who have Attended A,B or CWhen I do my normal query, I put the fields in, but if I put a date filter in Event A, it will not show up any person who may have attended event B but not Event A.I thought about running an append query but this would mean running the data several times with possible duplication of client names.Ideally I would like to have my report to showDate: 31/07/2006Name A B CK.Brown Y YJ Blogg Y YK Smith YK Ellum Y Ythen I can just use a count at the bottom :)The methods I have tired will filter event date A, but will not show J BloggIf I create another append for Event B, and append that data to a table, then I will have duplicaion of K Brown.. Any Help Appreciated.Last thing - when I run the append queriy and get my duplications, the fields where I had a Y/N option - if it was YES then I get a -1 instead of 1 ??? Why? and how do I make sure that when appending that the Y answer is a 1 not a -1

Working in MS Access 2010. Data must be entered and updated in Access only. Trying to figure out if it's even possible to auto populate dates in multiple fields in a form that are triggered when I enter ANY date in a primary date field on the form. I have close to half a dozen fields I'd like to do this for but here are a couple of the fields I'm working with:
Re Insp Date 90 Day Notice(Form field to be triggered and show a date 90 days prior to the trigger date)
Re Insp Date 60 Day Notice (Form field to be triggered and show a date 60 days prior to the trigger date)
Re Insp Date (Trigger date)
What I'd like to do is enter values in the "Re Insp Date" field (in the form) and have it trigger/auto-fill/auto-populate the "Re Insp Date 90 Day Notice" so that it shows the date 90 days prior to the "Re Insp Date" and the "Re Insp Date 60 Day Notice" so that it shows the date 60 days prior to the "Re Insp Date"........all this, and have it auto-update the queries and tables its linked to.
I've tried looking online and in instructional material to see if there is a formula, equation, macro, an expression or VBA coding that I can use to execute this but am having no luck.
The MAIN OBJECTIVE is to have the the linked query and table update automatically. Possible??
I have tried doing =([Re Insp Date])-90 but no dice...

The query is there to query data, not to edit data or manipulate data in anyway. However, I am disgusted by the appearance of the date picker when I pick a field that is a date field.
Is there a way to hide/remove these date pickers from the query sheet?
Within the table itself I turned the "Show date picker" property to "Never" but that didn't make a difference.

Help - Why don’t my date fields sort in date order ?
I’m having a very annoying problem with my date fields. I have a database that keeps records of patients details and their visits to the practioner.
I have a form based on Patients table with name address etc, and a subform based on a Case Details table with details of visits and advice given etc.
I need the Case Details subform to display the latest visit/record at the bottom (the earlier visits at the top of the list). For some reason I just cannot achieve this. Dates seem to be scattered all over and I can’t understand why ??
I have tried sorting the Case Details table in ascending order, sorting the ‘Date of Visit’ field on the form in ascending order (which does work but as soon as the form is closed and re-opened, all the dates are mixed up again).
In the ‘OrderBy’ property of my Case Details Subform, it says:-
[Case Details Table].[Date of Action]
which according the help I have tried to look at should sort the records ??
I’d really appreciate any pointers as to where I’m going wrong

A small issue I was wondering of for a few day . Is it possible in SQL query to SELECT multiple fields from multiple tables ? Example for the question is
Code:
dim my_var as String
my_var = "SELECT Emp_FName , Emp_LName , Emp_Adress " _
& " FROM Table1 " _
& " AND Emp_Date_Of_Payment , Emp_Sum_Of_Payment " _
& "FROM Table2 " _
& " WHERE Emp_ID = 3 "
Is this code actually valid in SQL gramatics , and is it usable if passed to a Recordset variable ( rs = CurrentDB.OpenRecordset(my_var) ) ? Just FYI - The two tables are not related and I want to keep them that way (If possible relate their records just via SQL/Vba )

I have a database with date and time each stored in a separate field. Now I want to query the database based on a start date/time and an end date/time. I started with the code below but it only returns events within the same time range on each day when what I really need is every event from a specified date and time through a specified date and time.
SELECT myTable.ID AS myTable_ID, myDate, myTime, FirstName, LastName
FROM Staff INNER JOIN myTable ON
Staff.ID = myTable.StaffID
WHERE myTable.myDate >= #3/2/2014#
AND myTable.myDate <= #3/3/2014#
AND myTable.myTime >= #8:00PM#
AND myTable.myTime <= #11:00PM#
ORDER BY myDate desc
In the above example what I want is every event from 3/2/2014 8:00PM until 3/3/2014 11:00PM. But what I get instead is every event between 8:00PM and 11:00PM on 3/2/2014 and every event between 8:00PM and 11:00PM on 3/3/2014.

Hi all,
Firstly, I'm an ex-fulltime access developer who has found himself doing access work again 6 years later; I can't actually believe how much I've forgotten :s
Anyway, I've done a search and havn't found anything that can help me so wondered if anyone could give some advice.
I have an access form with 3 combo boxes and a checkbox next to each of them. these are accessed using a query with 3 iif statements in it stating; (iif checkbox is null, "*", combo_box_value). the whole query looks like this
SELECT Customers.*
FROM Customers
WHERE (((Customers.Partner)=IIf(Forms!frm_rpt_main!check _partner Is Null,"*",Forms!frm_rpt_main!partner)) AND ((Customers.[Type Business])=IIf(Forms!frm_rpt_main!check_type Is Null,"*",Forms!frm_rpt_main!type)) AND ((Customers.[Year End Month])=IIf(Forms!frm_rpt_main!check_month Is Null,"*",Forms!frm_rpt_main!month)));
However, the query only seems to want to pull data from all 3 combo boxes
My issue is that if a checkbox is not ticked, I want the values to be ignored for all 3 combo's.
I've attached a copy of the mdb file as my description probably doesnt make any sense, the specific query is "qry_select_month_partner_type_wname_frm_rpt"
Thanking you all in advance for your help!

When I enter a date only results for that particular date are visible.
Can anyone suggest how i can expand this to include all live assignments?

Hello,
I'm trying to make a report query work but with no succes so far. Can anyone please help me?
I've got a multiselect listbox and a txtbox (txtCursisten) where the results from the multiselect listbox appear.
I want to get the results out of a table (tblAbsentie) where I can set a start and end date AND use the people selected in the txtBox. So far I've got a NOT working query, a report based on the query and a button on my form.
The VB code behind the "show report" button is this:
Private Sub cmdAbsentiePerCursistPerPeriode_Click()
On Error GoTo Err_cmdAbsentiePerCursistPerPeriode_Click
Dim db As Database
Dim Q As QueryDef
Dim sql As String
If IsNull("Me.txtCursisten") Or Me.txtCursisten = "" Then
Exit Sub
Else
Set db = currentdb()
Set Q = db.QueryDefs("qryAbsentiePerCursistPerPeriode")
Q.sql = "SELECT tblCursist.Naam, tblAbsentie.Datum, tblAbsentie.Lesuur, tblAbsentie.AantalLesuren, tblAbsentie.Deelkwalificatie, tblAbsentie.Docent, tblAbsentie.Gemotiveerd, tblAbsentie.Reden, tblAbsentie.Status, qryCountLesuren.SumOfAantalLesuren" & _
"FROM (tblCursist INNER JOIN qryCountLesuren ON tblCursist.OVnr=qryCountLesuren.OVnr) INNER JOIN tblAbsentie ON tblCursist.OVnr=tblAbsentie.OVnr" & _
"WHERE (((tblAbsentie.Datum) Between [Voer begindatum in] And [Voer einddatum in]) AND ((tblAbsentie.OVnr) In ("Me!txtCursisten"))); "
Q.Close
DoCmd.OpenReport "rptAbsentiePerCursistPerPeriode", acPreview
End If
On Error GoTo 0
Exit Sub
Exit_cmdAbsentiePerCursistPerPeriode_Click:
Exit Sub
Err_cmdAbsentiePerCursistPerPeriode_Click:
MsgBox "Selecteer klas en cursist(en)."
Resume Exit_cmdAbsentiePerCursistPerPeriode_Click
End Sub
I get a syntax error when pressing the button. Please help...

1/010/1-8TCOWLFEEDER 2005-11-09 40
Out of the records above I would only want to see the records with the 2005-11-09 date. The dates can vary based on processes so I really need something that selects the the latest date for each Process and Operation. I would like to do this in a query or multiple queries.
Thanks for any help.
