I am having a problem, probably due to my inexperience with Access. Here is the seniero:
-I have a form/table set up for operators to enter numbers on a daily basis.
-I am setting up queries/reports to display not only the entered data, but also calculated values from the entered values
--I have no idea on how to subtract a previous day's value from today's value and report that value.
- Since Access gives no "ownership" to any value I do not know how to reference yesterday's value in today's calculation.Any Ideas?
I am trying to get a very simple thing done in Access and I must have spent almost over 2 days of Internet time to do so. My problem is that I need to get the difference in 2 records to show in a query.
e.g. MyTable has 2 fields: 1. MyDate 2. MtrReading
Everyday I enter date in MyDate and a number in MtrReading. And I need to find out the difference between today's MtrReading and Yesterday's Mtr Reading.
Hello, I am trying to generate some query result on a form. My DB consists of the following fields : tradeID and profit/loss. How do i make a query to find the Maximum consecutive number of wins and losses in the database and display the results on a form?
Would really appreciate it if any of you have tried to sort and display results for finding consecutive number of events in any database!
I want to place a control in a report footer that will return the highest number of consecutive weeks that a profit was earned. The database has fields named WeekNo and Net. The Net field contains positive values (profit) and negative values (losses). The WeekNo field is an integer from 1 to 52 designating the week number.
For example if the figure in the Net field is a positive number I want the control to count the number of consecutive weeks that a profit was earned. I know how to get the value of total weeks that a profit was earned; this is not what I am looking for. The control must return the highest number of CONSECUTIVE weeks that a profit was earned over the year.
I want subtrack a value on the current record from the previous record and display the result in text box in subform datasheet. This is done during data entry. The calculation works most of the time and randomly it returns the wrong value. I have the code in an after update event after I enter a number. Here is what my code looks like:
I think my subject heading explains it. How would you add or subtract two short time formatted values and produce a short time value? Also, how would you change a short time value into number minutes. (i.e. 5:30 into 330) Thanks!
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').
I have atable the is storing ID, attendance_year and meeting code. Iw ould like to query the table and identify the IDs that have 10 consecutive attendance years no matter when it may have occured. So IDs have more than 10 row of data but not necassrily 10 years in a row.
Firstly I have placed this in the general section as I am not quite sure if any vba would need to be created for the following. I would also like to report on the information but the answer may not be done at report level.
Anyway, I have created a very basic database that holds staff attendance and their reason for being absent.
I have a Student Attendance table and it would be great if I could get some way of automatically determining if the attendance status is Absent - Unexcused for two or more consecutive sessions in order for someone to get in contact with the student.
I have a table of employees, and dates they worked on. These are seasonal employees who want to get in as many days as possible before the season ends, but regulation states they must take a compulsory rest day after x days.So I need to create a query that can return the list of employees, with a count of consecutive workdays up until current date.
If today is 20/09/2013, and Johnny worked on, 19, 18, 17, 15, 14, 13, his count must be 3, because he was absent on 16. Therefore only from 17 through 19 is regarded as consecutive.
If Peter worked 19, 18, 17, 16, 15, 14, 13, his count would be 7, because unlike Johnny, Peter still worked on 16.
I have data for multiple account numbers (for work) and dates, and I need to identify when there is a change in account number in order to add a new field with a count - which counts sequentially starting with 1 and then starts over at 1 when the account number changes.
Hi there, Some scene setting to my problem. I have a corporate system numbering invoices consecutively globally. For a subsidiary in Poland this presents a problem - all invoices for the subsidiary must be consecutive. ie. where the globally issued invoices for Poland might be 1,4,5,7 these need to be renumbered before issue in Poland.
It gets more complicated as the Polish Office standard is to invoice in the format "PL/Year/Month/Number" with the Number restarting from 1 for each month.
My database is very simple. Table 1 = Link table to Oracle corporate data Table 2 = Local table of invoices already produced (Global invoice number and date recorded)
I have a filter to find all new invoices (unmatched items), a report to print them and an Append query to populate the new items to the Local table.
My challenge: (1) to recreate the Polish numbering scheme and (2) have it consistently when existing data goes up to mid month and a new append operation has to follow the invoice number sequence.
Any ideas? I guess Autonumber is no good and I have little array experience.
I am setting up VBA to run multiple append queries in consecutive order. The append queries are supposed to pull a four digit number off of a form that will allow them to know which data to append. I want the number to be stored as text to correspond with the tables I am working with, but I am having trouble getting the form to work.
Here is how I would like it to work:
I enter my 4 digits in the text box on the form. Say "1305" for May 2013. I want to then run my vba (my queries update using the forms!txtupdatequery!textbox I have put in the criteria of the queries) and all of them run.
I enter my date (as a number but I want it to be text) and the form gives me a #name? error.
I am trying to create a form that creates an automatic identifier with a value one greater than the previous identifier. I was able to create something that updates in batches of two: That is, I end up with identifiers that go 1, 2, 2, 3, 3, 4, 4, etc. How do I get it to create consecutive identifiers (1, 2, 3, 4, etc.)?
I'm trying to do a calculation in access that will allow a user to receive a discount in one field and show the results in another. The form looks like this. Having a hard time figuring out the line total. It's giving me a the wrong amount. The employee discount is $.20 and the price is $2.27 for example.. Thanks
Bound text box [UnitPrice] - Bound text box [EmployeeDiscount] x Bound text box [Quantity] = Bound text box [LineTotal]
I am familiar with databases and basic SQL, but never used Access, so your help is greatly appreciated!
What I *think* I need to do here is take the results from one query, subtract another query from that, then create a table of the results, so that I can make a chart in a report. I say that I *think* I need do that because Iím not confident that this approach is the best but thatís a whole other story...
Please look at the following tables below for an example. The Item table has ItemCode as a primary key. The Bids Table has multiple rows for each ItemCode showing bids for the item:
Item Table ItemCode Date Address JH231 2008-Feb-20 123 Test St. KH831 2008-Feb-21 512 Test St.
To make a pretty graph, I would like a table (so a query, or macro, or VBA or something?) that returns the minimum Amount for an ItemCode subtracted from the maximum Amount for an ItemCode based on the example above. What I would end up is something like this:
ItemCode Difference Between Maximum and Minimum JH321 250 KH831 80.00
I hope this is clear. Any help on how to do this from you Access pros would be great, OR if Iím taking the wrong approach, suggestions on what I should try next. Thanks!!!
