Queries :: Select All Dates Since A Given Date Without Referencing A Table? (Access 2007)
Apr 23, 2014
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 have a table of records, which has within it two date fields (effectively, a 'start' and 'end' date for that particular record)
I now need to create a query to perform a calculation for each date between the 'start' date and the 'end' date
So the first step (as I see it anyway) is to try to create a query which will give me each date between the two reference dates, in the hope that I can then JOIN that onto another query to perform the necessary calculation for each of the returned dates.
Is there a way to do this?
So basically, if for a particular record, the 'start' date is 01-Apr-2015 and the 'end' date is 09-Apr-2015, can I produce a dataset of 9 records as follows :01-Apr-2015
02-Apr-2015
03-Apr-2015
04-Apr-2015
05-Apr-2015
06-Apr-2015
07-Apr-2015
08-Apr-2015
09-Apr-2015
(The *obvious* solution would be to create a separate table of dates, from which I could just SELECT DISTINCT <Date> Between #04/01/2015# And #04/09/2015# - but that seems like a dreadful waste of space, if that table is only required to generate the above? And it would have to cover all possible options; so it would either have to be massive, and contain every possible date - ever! - or maintained, adding new dates as necessary when they are required. Seems horribly inefficient!)
Is it possible to just select each date between the two reference dates? Or can you only query something which exists somewhere in a table?

I have a table of logged entries. Each record has a date field (ValueDate) and an account identifier field (AccountID)
I also have a table of rates. Each record has the same account identifier field (AccountID), a date field (EffectiveDate) and a rate field (BankRate)
Entries can be logged for any given ValueDate. But there may or may not be a corresponding EffectiveDate in the rates table.
I need to write a query that will return all of my logged entries and the largest EffectiveDate which is on or before the ValueDate (as well as the BankRate corresponding to that EffectiveDate)
This is as far as I've gotten but it returns multiple records for each logged entry. I need one record per logged entry.
Code:
SELECT tblLoggedEntries.EntryID, tblLoggedEntries.AccountID, tmp.BankRate, MAX(tmp.EffectiveDate) AS EffectiveDate
FROM tblLoggedEntries
LEFT JOIN
(SELECT tblRates.AccountID, tblRates.BankRate, tblRates.EffectiveDate
FROM tblRates) AS tmp ON tblLoggedEntries.AccountID = tmp.AccountID
WHERE tmp.EffectiveDate<=tblLoggedEntries.ValueDate
GROUP BY tblLoggedEntries.EntryID, tblLoggedEntries.AccountID, tmp.BankRate

If you want to use a "DoCmd.RunSQL "INSERT INTO" command to insert data in a table and the data to insert comes from a table and a form, could this be done in one pass?
So...writing a record wit 4 values from table1 together with a additional value from a textbox in table2 as 5 values.

I have a table which includes a start date field and completion date field for housebuilding.
I am trying to extract all records that have either a started date or a completed date between 2 dates supplied by the user. I have tried to use Between on both fields but that doesn't return results between the fields.
It workd if I just do it on EITHER the start date field OR the completion date field so that implies to me that I need to break it into 2 queries, one returning start date recrods and the other returning completion date records but then I would need to have somthing that removes records that appear in both the start date and the completion date results.

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)

Is it possible to run a SQL command to update a field within a table with random numbers?
More specifically - random long integers linking back to an ID (autonumber) field in another table?
Background to this is, I have multiple static data tables related to each other by long integer identifiers (autonumbers)
The structure is fine but I haven't been provided with the actual data yet - but for development purposes, I need to work on other functionality which requires that this data be present.
So I want to fill my table with dummy data such that I can go off and work on the remaining functionality, but then just go back and clear it all out once I get the actual data.
I have one 'main' static table, which links back to other tables, which I have already populated with dummy static (i.e. company names, locations etc) Now I want to go into my main table and populate those fields in each record with a random ID. I don't mind doing this field-by-field (there's only a handful) but I've a lot of records in there (~1000) so I'd rather not do this record-by-record.

I have a table with only two fields and one record: BegDate and EndDate (beginning and end date of the reporting period respectively). I also made a function with variables that look up those values for use as a date parameter in a query.
Here is the code:
Option Compare Database
Option Explicit
Public Function getCurrentRepDates() As Date
Dim dtBegDate As Date
dtBegDate = DLookup("BegDate", "tblCurrentRepDates")
[Code] ....
I am getting a syntax error for the line marked red. How can I use "Between" function in VBA code? Access 2010

I have generated two queries called "qry_GetWellName_GetAPI" and "qry_GetWellProduction" that extracts all the data I need from a csv to make two tables.
My issue is that I can not gather all the production data into a query formatted properly for a make table query that contains production history by month / api number.
Ideally the data would be placed in a table called tblProductionHistory with the following unique table index --> [api_fk] [data date]. The api_fk would link to the table that was created by extracting well names using qry_GetWellName_GetAPI.
tblProductionHistory field structure I am trying to achieve:
[api_fk]--[data date]--[oil rate]--[gas rate]--[water rate]--[days produced]--[cumulative oil]--[cumulative gas]
Currently the qry_GetWellProduction shows each well name and the year it had production as a separate record from the month names and the month's production values. I need to consolidate the data so each record can be matched to the unique table index.
Is there a sub query I need to use to manufacture a data date for each month that includes the year and last day of that month for that year? Also would I need a separate sub query to match each month's production to the api number?

I have made a new access 2013 database. I have created a linked table that has imported a substantial amount of data from an external data source, (an Excel spreadsheet). So far no problem. I created a select query that plucked data from the original table mentioned. Again, no problem. Then I decided to create another table, using certain fields only from the select query. Microsoft's guide tells me to start with CREATE, then Table design. I am happy to use just 4 fields from my query, but what I keep ending up with is a table, that, when I double click on it gives me the following:
ID Field1 Field2 Click to add
(New)
It is presumably expecting me to enter an ID number and it will come up with some record, but I want a complete table that should show several hundred records.

such as: I want to find title is manager and sex is F and datebirth from 1965/1/1~1973/12/31.
I'm lack skill in Access and tried to find this answer for a long time, every suggestion will be appreciated, thanks so much in advance.

I have a main menu "MainMenuF" in my database and I would like the database to be able to be searched by any of the column headings. For example I have a table titled "NewLabReportT" this table has many column headings like "Submitted By" "Reviewed By" "Title" "Abstract" etc...
I would like my users to be able to click a radio button with the same column headers on this main menu and have a box that pops up to say "Enter search parameter" and have that parameter be searched in the table "NewLabReportT" and generate a FORM not a REPORT of all of the listings in the database that have that keyword associated to that certain category searched. That way they can "CLICK" the exact field they are looking for and have it open right up to that form.

I have two queries, one base upon the other. I would like to combine them (If Possible) into one query so I can embed them into a form or report. I have tried without success at finding the answer on the forum as well as searching the web.
The table lists employee numbers and dates they worked. I need a count of how many employees worked each year, based upon the paycheck date, not the actual date worked. Pay check dates are two weeks apart. An extreme example, is the first pay check date of 2010 was on 1/1/2010, but all the days worked were in 2009, this would have to be included in 2010 not 2009(See the query for further date calculation understanding). Anyway, the date calculations are not the issue here.
I only have one table, so if I am not mistaken, I can't use the WHERE (SELECT... JOIN) feature. I also was unsuccessful at using SQL DISTINCT.
I am running ACCESS 2010 Tables are ACCESS 2007.
OS is Windows 7 Ultimate.
I have included a same database with the queries. qryEmployeesAnually2 is the results I am trying to achieve.

Attached is a screenshot of the relationships in a database I built a couple of years ago. It's worked absolutely fine in Access 2003 and currently has over 18,000 customers with associated information in it.
However, when I open the database in Access 2007 the performance is awful. All the forms are very slow to respond when tabbing between form elements. I've experimented by reducing the number of form elements calling on related data on a given page and whilst this improves performance it reduces usability - something I don't want to compromise on especially since Access 2007 should be able to cope with this.
My next question is therefore whether I've got the most efficient underlying table design and I can't see any other way of doing it than my current method so I'd be grateful for any feedback or advice anyone has.

I'm trying to select a range of relevant dates for an amortization calculation (see my earlier thread on this subject here), but I'm having a bit of trouble making the SQL work.
I have a table called "t_AllMonths" that has only one field: MonthStartDate which contains the first day of the month for a very wide range of months over something like a ten-year period. I'm calculating amort for assets which will be amortized for some subset of those months (defined by the asset's Amort Start Date and Amort End Date). Further complicating matters, the amortization may be suspended during certain "hiatus" periods when the asset it not planned to be in use, and may differ by which business units make use of the asset.
So, I have three tables.
Table: t_Assets
Fields: AssetID (autonumber; primary key), Asset_Name, Asset_Cost
Table: t_AllMonths
Fields: MonthStartDate
Table: t_AmortPeriods
Fields: AmortPeriodID, AssetID, Amt_Period_Num (which I don't expect to use in this), StartDate and EndDate
Right now, I'm just trying to pull the range of dates between the earliest amort start date and the latest amort end date. (Min of StartDate and Max of EndDate, respectively) for a given AssetID.
My sql looks like this:
SELECT t_AllMonths.MonthStartDate,
Min(t_AmortPeriods.StartDate) AS MinOfStartDate, Max(t_AmortPeriods.EndDate) AS MaxOfEndDate,
t_Assets.AssetID
FROM t_AllMonths,
t_Assets INNER JOIN t_AmortPeriods ON t_Assets.AssetID = t_AmortPeriods.AssetID
WHERE ((t_AllMonths.MonthStartDate) Between [MinOfStartDate] and [MaxOfEndDate]);
I keep getting an error message that reads "Run-Time Error 3122: You tried to execute a query that does not include the specified expression MonthStartDate as part of an aggregate function."

I've built an an update query that updates a Yes/No field "Expired?" to "Yes" if the expiration date has passed i.e. if the current date is newer than the expiration date. I thought this would translate into the current date being greater than the expiration date?
UPDATE Alert
SET Alert.[Expired?] = 'Yes'
WHERE Alert.Current_Date>Alert.Expiration_Date;
When I run this, it identifies the records to be updated, but then stops updating the fields due to "a conversion failure."

I am creating a query to use in a Word 2007 mail merge.
For simplicity, let's say the query has three fields:
schname for school name, role for staff role, and name for the staff member's name.
The current query shows:
SchoolA, Admin, Jerry Garcia
SchoolA, President, Bob Hope
SchoolB, Admin, Janet Jackson
SchoolB, President, Mae West
I would like a query that would show one line per school like so:
SchoolA, Jerry Garcia, Bob Hope
SchoolB, Janet Jackson, Mae West

For example:
A record for John Doe has him start vacation 08/19/2014 and end vacation on 8/28/2014. If I wanted a report that shows who is on vacation today, 08/25/2014, using the date() function), how would I do this?
