Queries :: Round Query Values Up To Nearest Table Value
Sep 15, 2014
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 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 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.
I have a timesheet database, which has the exact start time and exact end time. I want to ignore this if it is five minutes either side of the half hour, and display the exact half hour, but otherwise want to round it UP to the nearest fifteen minutes.
I have an expression that sets an AI Buy It Now value that is 125% of AI Value and rounds it, which follows AI Buy It Now: Round(([AI Value]*1.25)/10)*10
I need to add to this expression that I only want this calculation applied if AI Values are greater than 999. But I can't figure out how to add this stipulation to the above expression. I have tried IIF but it is not working.
I have about ten append queries to group various financial data to one main table.
I have used the round function (iff (Round(Nz([FIN_data]),2)) in the queries to round the original data into 2 decimal places but there is still one or two lines exceeding 2 decimal places.
What is the better approach to have only 2 decimal places for all append data?
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.
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 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?
Let's say Table (T1) has fields F1 and F2. After a massive update to T1, there are some records with F1 = "" because a Dlookup using F2 as criteria to another Table (T2) resulted in a null. I created a select query to show unique T1F2 values where T1F1 = "". The user can use this query to find out which F2 values need to be added to T2.
How do I create an update query that will update T1F1 with values from T2 using the T1F2 results from the select query to again use the Dlookup to T2 (of course after T2 has been updated to contain the missing F2's)?
I'm using Access 2010. I need to calculate a score based on values selected in a table by looking up corresponding values in other tables. I have a "Project" form to create new entries into the Project table (see Table 1). When I create a new project record, I will select values for the Payback and Need fields by selecting options from a list. The Payback list is pointed at Table 2 and the Need list is pointed at Table 3. In the below example, I created the "ABC" project and selected "1 year" for the Payback field and "Repair" for the Need field. Pretty simple.
Now that I have the "ABC" project loaded to my Project table, I'd like to create a report that will show a "score" for this project. The score should be calculated as follows: Payback Impact + Need Impact. In this example, the score should be 30 (Payback Impact of 20 + Need Impact of 10).
I have a query with an INNER JOIN and ORDER BY that is working great. Now, using the same JOIN, I need to update values in one table with the values in another. I thought it would be simple until I learned you can't do an ORDER BY with an UPDATE. Is there another way to achieve the same result? If you remove the 'ORDER BY', the statement below doesn't produce an error but the results are not correct:
UPDATE TableA INNER JOIN TableB ON (Left(TableA.CDN,6))=(TableB.CDN) SET TableA.HCC = TableB.HCC WHERE TableB.HCC Like '241*' AND TableB.BBB = 'X' AND TableA.CCC = "1234" AND TableA.HCC IS NOT NULL ORDER BY TableB.HCC, TableA.CDN;
I'm trying to determine the SQL to return only those records in a table which have duplicate values in each of two fields, but different values in a third field. Here's an example:
Code:
AcctNum FoodType FoodClass ------- -------- --------- A123 Apple Fruit A123 Apple Fruit A123 Grape Fruit A456 Potato Vegetable A456 Potato Perishable A789 Carrot Vegetable A001 Banana Fruit
For the above table, I'm trying to return records which have multiple entries for AcctNum + FoodType, but DIFFERENT values for FoodClass. So for the above table, the query would return:
It returns these two records because there is more than one record with for the AcctNum + FoodType (i.e. 'A456' + 'Potato'), but DIFFERENT values for FoodClass (i.e. one record has 'Vegetable' while the other has 'Perishable').
In a query I have placed functions that work fine. Now I needed to round a currency number to the nearest $10. ex. 224.49 would be 220.00. I used round(xxxxxxx,-2). this gives me an error. positive 2 works fine. What's the deal? thanks for anyone who can help me. :)
I track reports in a database. I have a date field [Approval_Date] in the database table. I want to review the reports after they have been approved for 6 months to see if the actions fixed the problem, so I created a query based on the table and used the code "6-Month Review Date: [Approval_Date]+180". This works great except that our meetings are always on Wednesday. So, is there a way to modify my code so that it calculates the 6-Month Review Date as 180 days after the Approval_Date, but then rounds up to the next Wednesday?
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 have two tables (Table 1, Table 2). Table 1 is blank and has the fields "Field1, Field2, and Field3." Table 2 has data and 10 different fields ("Field1, Field2", etc). I want to copy all data from the matching fields in Table 2 to the corresponding Table 1. I've tried an Update Query in design view. Did not join any records, and just a simple:
Field: Field 1 Table: Table 1 Update To: [Table2]![Field5]
This returns 0 records to update. I thought about a Make Table to override the entire Table, but that isn't working either.
I have a query that takes a value, Proposalvalue, and depending on the currency, loc curr, it calculates the currency. It gets the currency value from the currencies table and appends to TableB
eg. proposalvalue currency 50000 1
Currencies id Value 1 0.6587
This creates the conversionvalue = 32935 in the TableB.
I have a form that can viewedit the data in TableB.
Using this form, I want to be able to change the proposalvalue and for it to automatically update the conversionvalue.
inserting values from a listbox in to a table. I have a table with a field named: PrefReports. This field will hold data from values in a list box that the user selects.
Table: Profiles Field Name: PrefReports Type: Memo
The user utilizes a form to input the values necessary for the query. I then have the query tied to a command button. When the command button is clicked, the query is executed.
How can I take what the user selects in the list box, and insert into my TblProfiles.PrefReports field? When I run the query, all other information makes it to the table except the list box values.
I have a table having fields start date and end date. I need to calculate difference in the dates and store the values in a new column in the same table. I am able to write the query for this but am clueless as to how to put in these values in a new column in the table.
I am trying to write a query that gets all the telephone hours from a worker done under supervision in a town (qry_svhoursbytown). I have a table that has the workers details, including town (Crisis_support_workers), then another table that has what hours each worker has done (Supervision_Hours). The town is selected from a combo box on the form (frmSearch), under the heading �total hours by location�.
I try and select Bathurst then press recalculate results and in the text box next to supervision hours, it says 66, but if you look in the Supervision_Hours table, there is only 11 hours for the workers that are in Bathurst.
In the query, I have the sum total of the hours field in the Supervision_Hours table, the Town field from the Crisis_support_workers table with the total selected as Where and in that criteria I have [forms]![frmSearch]![ComboTown], then I just have the town field displayed.
What do I need to change to get it to sum correctly?
I have attached the database below so people can take a look.
