I need to find the nearest dates between two tables.
Table1 contains dates 11/1/2006 to 11/30/2006
Table2 contains only two dates:
11/5/2006
11/19/2006
I want Query1 to produce the nearest date in Table2 beside each of the dates in Table 1.
Example:
Date Nearest Date
11/1/2006 11/5/2006
11/13/2006 11/19/2006
etc.
I have a table that archives hour meter readings for my equipment. You sharp folks here helped me set it up and it works great. Thanks! I am at the point now where I want to do some studies and calculations on this data. The first project I’m working on is equipment utilization over a period of time. I have all my calculations figured out, all I need is to pull the proper data out and run it through. And that’s where I’m a little stuck.
My table is just three fields: tblHourMeterArchive = eqnum, readingdate, meterreading. I want to be able to input a StartDate and EndDate and have the query choose the archive date that is nearest to the input date and the meter reading on those dates. For example, I have meterreading dates of 1/9/05, 1/30/05, 6/5/05, and 6/19/05. I input 1/18/05 as the StartDate and 6/16/05 for the EndDate, the query should return the archive dates of 1/9/05 and 6/19/05. How would I go about doing this?
I’ve done some research on “nearest date”, but most of the information has been about doing it in VB and SQL. Can this be done without going into coding? I’m still very much a novice when it comes to VB code. Ultimately, I would like to have this work with a form and calendar controls. I’ve been studying some of the examples and suggestions for the calendars, but I’m not really sure how I would go about setting up a query in code and linking it all together.
As always, any help and/or links to information you could provide would be greatly appreciated.
I need to do a report that takes data from many different tables (like 10).
To do this I have a big query with many LEFT JOIN to link all the tables together. I have made this query last year and it worked well and efficiently until now.
But I have to add something there, and the problem comes with it :
One of the tables is a currency exchange rate table, with the exchange rate of USD to 50 different other currencies and for each day since Jan 1st 2011.
But in this table there are some dates when a currency does not have an exchange rate (example : it was a holiday in that country, so there is no official exchange rate with this currency on that day).
However, I need to have rates even if they are not present in the table.
I need to get the nearest rate, for example if the rate of EUR on 31st December is not available, I can take the one of the 30th, or 29th or January 1st...
Ideally I would like to do the following :
Add a new LEFT JOIN to my already big query that would look like :
LEFT JOIN CurrencyExchangeRate ON ABS(RateDate - Instrument.Date) < 3
But to take only the closest rate.
I tried with a subquery :
LEFT JOIN (SELECT TOP 1 * FROM CurrencyExchangeRate WHERE ForeignCurrency = Instrument.Currency1 AND ABS(RateDate - Instrument.Date) < 3) AS MRate ON MRate.ForeignCurrency = Instrument.Currency1)
But the subquery does not accept Instrument.Currency1 because it is not part of the table CurrencyExchangeRate
I have a solution that should work, it is to search for this rate in a subquery in the select clause instead of doing a left join. But the tables are quite big (hundreds of thousands of entries) and my work machine is not really 'fast' so it would take hours and hours (when I tried I stopped after 3 hours).
I know there is the solution to make a macro to "fill" the missing rates with the rate of the previous day... But I would prefer not to go to this extent.
I have main form call frmemployee and subform call frmlcourse subform the main form hold's employee information e.g. first name addresss the sub form hold's all the training courses that the employee has been on
I have a text box called txtnextcourse due to display when the next course due date is
Code:
=DMin("Expirydate","tblcourses","[ID]=" & [empID])
this works perfect. I have check box on my subform called ex course if this is true. I don't want the dmin to count that record I have tried
Code:
=DMin("Expirydate","tblcourses","[ID]=" & [empID]) [forms]![frmlcourse subform]![ex course]=false
I have got a formula in a Query as follows:
Suggested Qty: [StockQty]/[Numerator]
How do I round this down to the nearest 1?
(i.e 7.2 = 7 or 9.9 = 9)
Any help would be greatly received.

Hi, I am quite new to access, and have the following problem:-
I have a value that is returned in a report of say 17.93, i would like to round this number down to 17, similarly 9.13 should read 0
Can someone help please? Many thanks in advance
:)
I have been searching the forum for the last hour or so. I'm new to access, vba and macros. So I asking for some help, please be gentle with me. I'm am trying to round up the the nearest twenty.
example. I have a table that contains an estimate take-off f and I want to round the pipe footage to the nearest 20 for purchase amounts and update the table.
ie.
Item QTY
Pipe 534.08
Pipe 405.5
Pipe 28.83
Pipe 1381
Item QTY
Pipe 540
Pipe 420
Pipe 40
Pipe 1400
Another problem I'm not sure how to fix is, some of the qty totals are two decimals and others are nine. Maybe not an issue but thought it might be.
So if anyone is compelled to help a greenie out it would be much appreciated.
Thanks
Not sure what happened to my original post but here it goes again......I have a calculation that I need to perform in a query. Before I do the calculation however I need to round down numbers to the nearest hundred so a number like 1485.45 would be 1400, something like 543 would be 500 and something like 68 would be 0.In excel this is easy for me to do using the following formula/function:=ROUNDDOWN(C2,1-LEN(INT(C2)))Where cell C2 might contain something like 588 the net result is 500.How can I acheive this in Access (query)? There doesn't appear to be a rounddown function nor a len function in access.Any help is appreciated!M Opine
View 3 Replies View RelatedI have values for example like, 0.03, 1.14, 1.28 I'd like to round them to the nearest tenth. So resulting values will be as follows:
0.03 = 0.00
1.14 = 1.10
1.28 = 1.30
How do i achieve this? What's the formula?
I'm trying to create a query that will return the closest matches to what is input. However the closest i have gotten to this working correctly is by using the following criteria.
Like Left([Forms]![TESTTESTTEST]![Text2],1) & "*"
Now obviously this isn't a great solution as it just produces results that match the first number but i need it to display results closest to the number entered into text2.
Basically i am doing this as a designer can search for a gap on a machine where there new project can fit on causing the least amount of disruption. So by entering in the size of there project the query will display jobs of a similar size that are already planned on the machine.
How can a I round to the nearest 10 cents
e.g
10.04 = 10.00
10.06 = 10.10
10.28 = 10.30 ........
I am increasing prices and after increasing I am left with 4 decimal places and am trying to figure out how to run an UPDATE query to round down prices to the nearest 5 cents, examples below:
42.4516 round to $42.45
42.4659 round to $42.45
42.4489 round to $42.40
2.49 round to $2.45
2.46 round to $2.45
2.44 round to $2.40
2.04 round to $2
I am using "Currency" format.
I would like to add fields from one table to another based on matching datetime codes.
Most data are in the table 'metadata' (information on sound recordings), and i want to add lat long fields from a large table of GPS points 'gpsData'. Each record in the metadata table has start and end datetime fields - i want to a add lat and long that matches the start time and a lat and long that matches the end time (so four fields to metadata).
My approach has been to try this with two separate select queries (i.e. one for adding the start locations and one for adding the end locations), with the intention of then combining these two outputs in a single table.
When i try a simple select query though I can see that:
a) there are no matching time codes for some records, because although the hh:mm:ss look the same there are differences in the lesser decimal places of the datetime serial numbers. I have tried using the round function on the datetime fields of both tables but this doesn't fix it (I don't understand why not).
b) there are some duplicates because there are sometimes more than one GPS point for each second, and the metadata times are given to second precision (so some metadata records get two entries in the query result).
How can I have the query select the gpsData record with the nearest datetime stamp to that in the metadata table's start time field? The respective field names are UTC and StartUTC. Can i do the same for the end times simultaneously or should i do this separately?
I have Territory Mgmt database. Sometimes when I get a new lead I need to quickly find other leads in the database that are closest to it.
I am currently not tracking latitude/longitude etc. Do I need to? Is there a way to set certain location marks by address?
If so, once I put in the latitudel/longitude how do I create a search to find the nearest?
I have a table of standard Circuit Breaker (CB) sizes. I then calculate a minimum CB size in a query field. I want to use that calculated minimum value to look up the next largest CB size from the table and fill a field in the query with it.
For now, I am going to add a field to the CB size table with the smallest size CB which would be assigned that standard value. I will then use a Dlookup with conditions of greater than "smallest size" and less than "standard size" fields from the CB size table.
I think this will work fine, but there must be a better way.
I have a field that sums pounds. I need to convert this to tons (rounded to the nearest 3 decimals), then multiplied by $67.50. This will calculate a fee payment.
This is what I have now:
Code:
=Round(Sum([Hazardous_Waste]/2000*67.5),3)
The total pounds is 2675.
After dividing by 2000, Access generates a number of 1.3375. It rounds 1.3375 to 1.337 which generates an incorrect final total. Not sure how to alter this to round properly.
I am trying to round off times to the nearest half hour. To be clear, I don't want to only round down or only round up. I need the rounding to be to the nearest half hour. I want to do this in the query, not vba. I've attached a picture of the query.

Neither of which work ....
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.
Can someone tell me how to get year to date totals, month to date totals, week to dates in a query? I need to get all three for three different fields.
I was not able to get the totals with the formulas given. I received the totals for each day instead. Are there any other suggestions? I am trying to different formulas, but they are not working either. I did try doing different queries with the formulas to see if that would work.
I am creating an online post, similar to a guestbook. When a user submits an entry, I am storing the date and time in a column titled "Timestamp", which is formatted 8/4/2005 9:16:58 ("General Date"). I am running the table through a query which is then posted on the web.
What I would like to do is this: I would like to use Timestamp to display the date that the entry was submitted, but not the time (basically, "Short Date"). Can I exclude the time using a query without changing the actual data stored in each record of the table? I understand that the time stored is completely different than the time displayed, even in the table. How can I do this?

Using access 2010; i have a form that includes a date field. Is there a way to force the user to only choose a month end date? When the user clicks the date from the popup, they may use 9/1/2013 when the mgr. want them to use only 8/31/2013. I am thinking validation field to put a msg but want to be able to force it not the option.
View 2 Replies View RelatedI have a report that displays simple date fields. One of the fields is "lease execution". On the report, I want "lease execution" to display differently depending on the date the report was run.
So:
- If the "lease execution" date is more than 120 days away from today, I want it to display as Q YYYY.
- If the "lease execution" date is between 120 and 90 days away from today, I want it to display as MM/YYYY
- If the "lease execution" date is 90 days or less away, I want it to display the normal date MM/DD/YYYY
I was thinking I would need to do DateDiff() to figure out an amount of days that's between Now() and [Lease_Execution]. Then based on that amount make the report show it differently. Pseudocode would be: if DateDiff() = 40, then display [lease_execution] as MM/DD/YYYY
