General :: Date Calculation (Multiple Rows)
May 20, 2013
I manage the production schedule of over 150 reports. Some of which are due daily, weekly, bi-weekly & monthly. (some reports have multiple due dates for the current month.) I have the production schedule in a table with multiple DueDate columns: DueDate1, DueDate2, DueDate3, etc. Some reports are due every business day of the week. I need to:
1.) Display the due dates (without having to enter them manually) so I can perform calculations, conditional formatting, etc.
2.) Should I display a column for each due date (31 columns accross for those that are due daily?) or show a duplicate row for that report for each day the report is due?
Row1: Sales_Report, 5/20/13, Completed
Row2: Sales_Report, 5/28/13, Pending
Row3: Sales _Report, 5/31/13, Pending
Row4: Operations_Report, 5/2/13, Pending
3) is there a formula that can be written to autopopulate the duedate fields for every instance and every month? (Sales_Report due every Mon, Wed, Fri (5/13/13, 5/15/13, 5/17)
I am currently putting these dates in manually every month and it would be a pain to continue that given our reporting production schedule will only increase.

The project I'm working on is an action list with the following tables;
itemnumber - autonumber PK
originator - text
dateentered - date/time
actiondescription - text
assignedto - text
targetdate - date/time
forecastdate - date/time
actual date - date/time
remarks - text
due - text (not sure if this will be correct)
Basically, when a new task is entered, all info will be manually filled in except last 3 fields. targetdate needs to be locked after entry, and forecastdate initially set to targetdate.
"due" should show how many days between dateentered and forecast date, and preferably update everytime the DB is opened. IF the current date is beyond the forecast date, "due" should read "OVERDUE".
Changing forecastdate would obviously reset the "due" field to show how many days left to complete. If a date is entered into actualdate, then "due" should show COMPLETE.
Reports will be generated based on what is coming due, what is over due, and not show what is already complete.

I have a table with the following columns: Task, Visa type, time it takes to perform the task. There are several taks that are performed for all visa types. I want to create a form to enter data to the table in which for the field visa type I have a list box that can allow multiple values, however, I do not to create a single line with the task and on visa type all the types of visas selected. I want to create a line for each type of visa with the information introduced.
I don't know if this is possible, the reason for which I want for the form to create several rows depending on the visas types is because then I have a query that sums all the types of visas. Can this be possible? I don't want the people to introduce manually directly to the table the data and also that for the same taks they have to enter manually 50 rows with values. I want it to be more simple and easier.

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.
Query:
PARAMETERS [Candidate Name] Value;
SELECT [Assessment Tracker].Candidate, [Assessment Tracker].Unit, [Assessment Tracker].[EV1 Date], [Assessment Tracker].[EV2 Date], Max(MaxDate([Assessment Tracker]![EV1 Date],[Assessment Tracker]![EV2 Date])) AS Achdate
FROM UnitData INNER JOIN [Assessment Tracker] ON UnitData.Unit = [Assessment Tracker].Unit
[Code]....
Output:
CandidateUnitEV1 DateEV2 DateAchdate
TH11007/05/2015 25/05/201525/05/2015
TH11007/05/2015 07/06/201507/06/2015
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)

hi everyone, i have a table of timeseies data and would like to run a query working out the difference between the current row's value (day) and a previous row (day, or days before) and put this difference in a new column in the resulting query.
I know it would be straight forward in Excel to run a formula between 2 different rows, but this table has >1 million records and are appended with new records regularly.
Any help or inspiration would be greatly appreciated!

On my report, I want rows with expired dates to stand out by having their borders thicker. Something like:
Code:
If Me.txtDate < Date() Then
Me.txtDate.BorderWidth = 6
End If
When I do that, it ends up formatting every txtDate field in the report if one of them passes the If criteria instead of only ones that are expired.

Hello everybody....
I was given a task by my boss to create an appraisal system for our department here in one of the local schools in the Philippines.
Anyway, what I created first a form from which all subjects being offered will be displayed. I did this by having a main form (bind to personal info table) and a subform that displays all the subjects (bind to subjects table). Then, the user will simply click on the appropriate rows bearings the subejct that the students wish to enrolled and when the save button is click, such will be saved into the enrol table.
My questions is, what control will I use to allow me to select multiple rows? and how will I be able to save selected rows into the enrol table?
Thanks in advance and more power...

I'm trying to insert multiple rows into a table at once, but I'm having problems.
I've tried a syntax like this:
INSERT INTO [TABLE] ( [FIELD1], [FIELD2], [FIELD3] ) VALUES
(( '1', 'A', '1' ),( '2', 'B', '2' ));
..but with no success.
On a site I even found this other way, but with no success either...
INSERT INTO [TABLE]
SELECT '1', 'A', '1'
UNION ALL
SELECT '2', 'B', '2';
Is it possible to insert multiple rows and I'm just missing the syntax, or is it not possible with Access?

Could somebody please help me! I am new to access and trying to create a database that brings together information from a number of different sources, into one large database.
I need to import a large amount of data from another access table and I would like to just cut and paste it into my table.
BUT, I can’t figure out how to add multiple rows at once to my existing table. The data that I am importing contains about 6,000 rows and 4 columns. Can anybody tell me how I can do this without having to manually create 6,000 rows, one at a time? I really do not want to do that. Thank you for your help.

I am trying to insert multiple rows to a table using the query
insert into rvp (rvp, rvp_name, controller_id)
values (1200, 'rvp1', 10), (1201, 'rvp2', 10)
But I am getting an error "Missing semicolon( at the end of SQL statement" and placing a semicolon at the end isn't helping either. I can insert a single row so column type or primary key isn't a problem.
Here's the table structure,
rvp - number (pk)
rvp_name - text
controller_id - number
Can someone please help me out.

Hi, I have a table that has a start date field, a duration field and an end date field. I was wondering what I need to do so that the end date is calculated and entered when the duration is added onto the start date to produce the end date?
Should the date fields be set as a date, data type?
Sorry if this does not make sense ;)
Many thanks, Tobi

Here is the scenerio:
I have two tables:
tblDate: Contains on Months (i.e.Jan, Feb, Mar, etc)
tblActivities: Contains 4 fields Name, date, activity and hours
I have greated a form that allows me to select what month I want to see. It has a simple combo box in it that point back to tblDate.date. I setup a macro that is doing a OpenReport, there Where Clause is as follows:
[Forms]![frmMnthSelect]![Combo0] Like [tblVolunteers]![Date]
Of course this is not working, and I am at a loss.
I have a Query that is setup that is pulling all records for the current month, but I need to be able to select individual months, because I often have to pull reports for past and future projects.
Can some one start me out in the right direction......
Thanks,
Chuck

Is there a way to select several rows of records in a datasheet view of a table and delete all of the selected records?
Every time I try to delete more than one record at a time, I get the following message: "The Micorsoft Jet database engine stopped the process because you and another user are attempting to change the same data at the same time."
Then it will let me delete one record out of the selection.
I am the only one in that particular table at the time I am trying to delete the record.
Thanks in advance for your help...

Hello:
I'm new to Access but not SQL, and am having difficulty coming up with a solution to the following problem:
I have one table for all Strings used in all other tables (to make Internationalization easier). The fields are: zId, zType, and zString. zId is an AutoNumber field. zType is a number which defines what type of string it is ( Item Name, Person Name, etc. ). zString is a text field with the actual text string (can be empty).
I have another table for Items, which have (among other things) Names (field name= zName). zName is actually a lookup into the Strings table and stores just the ID.
I want to create a form for people to enter a new Item. When creating a new item using this form, they will have to give it a Name, which will need to add a new entry into the Strings table with the appropriate type (ie, Item Name).
So, my question is "How to do the following..."
* on my form to enter Item Data, when a user goes to create a new Item, I must first create a new entry in the Strings table with the correct value for zType. Then, I must get the value for zId for this new entry and assign it to the zName field in the Items table for the new record that I am creating.
Any help is appreciated.

Hello,
I am trying to find a way to combine multiple rows into one (field). I have 2 tables. One table is data the other table is notes. The notes table has a new record created for each new note. Both tables have the Account Number and and Sub Account Number. I am linking the two tables on these account numbers with a left join normally. There can be records in the data table and no records in the notes table. I guess what I want is a query or sql statement i can use in vba that will display all the data from the data table and all the notes from the notes table in on field.
This data is used in a large report. Right now I have the data table set to the report by itself and code on the report to pull the notes from the notes table using a ADO recordset with a do while that just adds each note to a single variable. This works fine and does the job. The only problem is the time it takes to run the report now. If the report has 1000 records with notes on 90% of them and each of those has multiple notes that recordset code has to run thu ALOT. I use to have all the notes just compile to one field in the data table and the report ran very fast that way. I had to change this since I need it this way as to filter notes by time and archive them after a period.
I have read thru so many posts and see lots of code functions to do this but its just the same thing I already have with the recordset code building the combined field. Any other way to do what I am trying? I think I have just been over thinking this stuff at this point an maybe a fresh set of eyes will help. Below are some simple table layouts for the 2.
**Account Number and Sub ID fields in both tables are not unquie.
Data Table: (this table has alot more data but this gives you the idea.)
Account_NUM - Sub_ID - Data1
1234 | 3 | 123 N Inc.
1234 | 3 | 666 DRN
4567 | 4 | 543 S Way.
7890 | 5 | zzz ABC
Notes Table: (Yes the notes field is a MEMO field)
Account_Num - Sub_ID - Notes
1234 | 3 | notes1
1234 | 3 | notes2
1234 | 3 | notes3
The output I am trying to Get:
Account_Num - Sub_ID - Data1 - Notes
1234 | 3 | 123 N Inc. | notes1 notes2 notes3
1234 | 3 | 666 DRN | notes1 notes2 notes3
4567 | 4 | 543 S Way. | NULL
7890 | 5 | zzz ABC | NULL
Thank you for any advice or thoughts.

I am trying to concatenate multiple rows into one record. I googled it and found many functions in VBA that do the job. However my problem is that my query will be linked directly to Excel file and then I get an error message saying that Excel could not recognise this function. I could potentially insert data into new table and link that table to Excel but I need to avoid end-user exposure to Access as much as possible.
So I am desperately trying to find a way of doing this without VBA code.
Example of data:
Customer Name |Order Number
Smith |O101
Brown |O102
Smith |O103
Green |O104
Brown |O105
I am trying to achieve below:
Customer Name |Order Number
Smith |O101, O103
Brown |O102, O105
Green |O104

I have a table where and account could have multiple rows with different data like Applied_Date and Trans_Code, and AMOUNT. The AMOUNT in two of the rows will be a positive and a negative and will be zero each other out. I am trying to create a query that will only return the the rows that do not offset each other. Here is an example of my table:
ACCOUNT CODE APPLIED_DATE AMOUNT
292020 M 5/11/2012 ($33.95)
292020 11 5/14/2012 $33.95
292020 A 5/30/2012 ($33.95)
