I'm quite new to access and I am currently in the process of making a database for my company.
I have a 'Jobs' table with these fields in:
Job No.
Year Initiated
Month Initiated
Company ID
Job Description
Amount Quoted
Amount to Invoice
Invoice Number
Completed By
Cost
Profit
What I want to know Is what is the best way/ how do I calculate either in a form or query the overall profit for each month?
Please help, the database is really coming along, apart from this is well entruely stuck on.
You want to find all rows matching a specific year / month, and add together all the profit entries for that month to get a total?
If so, try this :
select sum(profit) from Jobs where year = 2013 and month = 02
Or, if you want to retrieve this information for all months in one go, try this :
select year, month, sum(profit) from Jobs group by year, month

Problem Statement: I need to find out Over Due start date and from that i need to calculate number of Over due days. I know how to do for Over due days count, but i am not able to find a way to figure out for Over due start date.
Example: Let us say a customer did not pay for 4th November 2017, 4th December 2017, 4th Jan 2018, 4th Feb 2018. Now for these There were 4 Zero collection records placed in Collections table and 4 records placed in Over Due Collections table with D Flag. Now on 8th Feb Customer Paid an installment then the respective payment record has been placed in Collections table and another record in Over due collections with C flag. Since this payment gets adjusted for 4th November 2017 the Over due start date will be 4th December. Suppose if the customer did not pay then it will be 4th November 2017 as the Over due start date.
I have tables as follows for a Loan Management System:
Schedule (Payment Schedule): Which will have all the Installments, with the dates adn the respective amounts to be paid for each month.
Schema: LoanNo, Schedule Date, Installment No, Principle, Interest.
Collections (Payment Collections) for each month which has been collected. Suppose if the payment not received, A record placed with the respective date and with Zero amount. and another record will be placed in Over due collections table with D flag with the respective amounts. If there is any collection happens, then another record will be inserted with the flag C which represents collections.
Schema: LoanNo, PaymentReceived Date, Principle, Interest
Over Due Collections (Which there will be a record placed if there is a Due)
Schema: LoanID, Flag(D/C), Date, Principle, Interest
Please do suggest and guide me to write a proper query for this
it's interesting yet easy problem. you can tackle by calculating running sum of the amount and then compare with total payments by the customer. Take all the records having running sum greater than total payment. and choose minimum date out of it.
let me know if require further help I will give you SQL query. But you should try by your own
Edit 1
this will provide you running_sum
_______Subquery1_______
select a.LoanNO,a.Scheduledate,a.Amount,sum(b.amount)run_sum from
Paymentschedule a
join PayamentSchedule b
on a.LoanNo=b.LoanNo and a.ScheduleDate>b.ScheduleDate and
a.ScheduleDate<=now() group by 1,2,3
total collection against loan
_______subquery 2_____
select LoanNo,sum(amount)total collection from collection group by 1
now
select a.LoanNo,min(ScheduleDate) overduestartdate from subquery1 join subquery2 on
a.LoanNO=b.LoanNO
and a.run_sum>b.Collection group by 1
modify according to your schema
I'm using MS Access 2010 and am writing a program to display the lease amount to be paid over a period of 36 months. Once I have entered the contract into a table I use the following expression:
Charge: IIf(Date()>[1StartDate] And (Date())<=[2StartDate],[1Sched],
IIf(Date()>[2StartDate] And (Date())<=[3StartDate],[2Sched],
IIf(Date()>[3StartDate] And (Date())<=[4StartDate],[3Sched],
IIf(Date()>[4StartDate] And (Date())<=[5StartDate],[4Sched],
IIf(Date()>[5StartDate] And (Date())<=[EndDate],[5Sched],"0")))))
This shows the correct Rental amount to be invoiced but I would like to display the entire 36 months schedule so that when I run batch invoicing one specific month at a time will be ticket off as having been processed. How may I accomplish this?
I've created a new measure which uses [TotalSales] and 'SAMEPERIODLASTYEAR' to calculate the previous year's sales, see below:
=CALCULATE([TotalSales], SAMEPERIODLASTYEAR(Dates[Date]))
This all works fine if I create a pivot that displays individual dates (e.g. 01/01/2015) and then the new measure 'previous year sales' value next to it. My problem occurs when I want to change the pivot and display previous year sales by year, quarter or month - with any of these options I get no sales value.
I'm using a 'Dates' table which is linked to the Sales table.
Am I right in thinking I can re-aggregate sales in this way? I have seen an error message which says something about not been able to aggregate a non-contiguous value or date.
I've had a good look to see if anyone else has experienced the same problem, but can't see anything. Any guidance would be helpful.
Regards,
Martyn
Yes you can re-aggregate in this way. Your formula is correct would handles the changes to the aggregation level.
I would check that your 'Dates' table is marked as a date table. Ensure that the year, quarter & months are in this date table and not in your Sales table. Make sure that your date table has one record for each day between the beginning of your sales data set and the end. Check behavior in Power View if you are using Excel 2013.
I have a table named "Historical_Stock_Prices" in a MS Access database. This table has the columns: Ticker, Date1, Open1, High, Low, Close1, Volume, Adj_Close. The rows consist of the data for each ticker for every business day.
I need to run a query from inside my VB.net program that will return a table in my program that displays the growth rates for each quarter of every year for each ticker symbol listed. So for this example I would need to find the growth rate for GOOG in the 4th quarter of 2012.
To calculate this manually I would need to take the Close Price on the last BUSINESS day of the 4th quarter (12/31/2012) divided by the Open Price of the first BUSINESS day of the 4th quarter (10/1/2012). Then I need to subtract by 1 and multiply by 100 in order to get a percentage.
The actual calculation would look like this: ((707.38/759.05)-1)*100 = -6.807%
The first and last days of each quarter may vary due to weekend days.
I cannot come up with the correct syntax for the SQL statement to create a table of Growth Rates from a table of raw Historical Prices. Can anyone help me with the SQL statment?
Here's how I would approach the problem:
I'd start by creating a saved query Access named [Stock_Price_with_qtr] that calculates the year and quarter for each row:
SELECT
Historical_Stock_Prices.*,
Year([Date1]) AS Yr,
Switch(Month([Date1])<4,1,Month([Date1])<7,2,Month([Date1])<10,3,True,4) AS Qtr
FROM Historical_Stock_Prices
Then I'd create another saved query in Access named [Qtr_Dates] that finds the first and last business days for each ticker and quarter:
SELECT
Stock_Price_with_qtr.Ticker,
Stock_Price_with_qtr.Yr,
Stock_Price_with_qtr.Qtr,
Min(Stock_Price_with_qtr.Date1) AS Qtr_Start,
Max(Stock_Price_with_qtr.Date1) AS Qtr_End
FROM Stock_Price_with_qtr
GROUP BY
Stock_Price_with_qtr.Ticker,
Stock_Price_with_qtr.Yr,
Stock_Price_with_qtr.Qtr
That would allow me to use the following query in VB.NET (or C#, or Access itself) to calculate the quarterly growth rates:
SELECT
Qtr_Dates.Ticker,
Qtr_Dates.Yr,
Qtr_Dates.Qtr,
(([Close_Prices]![Close1]/[Open_Prices]![Open1])-1)*100 AS Qtr_Growth
FROM
(
Historical_Stock_Prices AS Open_Prices
INNER JOIN Qtr_Dates
ON (Open_Prices.Ticker = Qtr_Dates.Ticker)
AND (Open_Prices.Date1 = Qtr_Dates.Qtr_Start)
)
INNER JOIN
Historical_Stock_Prices AS Close_Prices
ON (Qtr_Dates.Ticker = Close_Prices.Ticker)
AND (Qtr_Dates.Qtr_End = Close_Prices.Date1)
I have two tables, one is income which consists of ID, income_amount and date
the other is expenses which is ID, amount_spent and date.
I'm trying to display a table with three columns the daily total of income, the daily total of amount and the date for that day, it is possible for that day to have no income or amount but not necessarily both.
I was able to display the table in visual c# by gathering them in individual tables and deriving the results programmatically but is there a way to achieve that table with just a single sql query?
trunc_to_day here is an hypothetical function which truncates a date to its day (you didn't specify what RDMBS you are using):
select sum(incomes), sun(spent), day from (
(select income_amount incomes, 0 spent, trunc_to_day(datecol) day from income_table)
union all
(select 0 incomes, amount_spent spent, trunc_to_day(datecol) day from spent_table)
) group by day;
Finally, if you want to limit to some days, use a where statement on it.
