I need to find a way to calculate total salary per employee per year
I have a list of employee's data which i need to sum their total salaries per each employee per year
below is sample data
This is basic use of SQL that would be covered in any class, book, or online course. In general you should not ask these "how do you code it" questions on this site but instead ask questions about code you have already written, we are not here to write it for you we are here to help if you have problems. On the other hand it is easy:
select employee_no, year, sum(sal_amount)
from table_name_you_did_no_say
group by emplyee_no, year
You could make yourself a formula like this:
salary_per_annum = salary_per_month * 12
What you really need to do is to first categorize your staff based on the salary they earn.
If they earn allowances/bonuses, you could make a different calculations for that too and then add the both values.
If you're talking of an SQL query, for each employee, you could loop:
select sum(salary) * 12
If you're looking to calculate and group, you could have:
select employee_num, sal_year, salary from tbl_payrol group by emplyee_num, sal_amount

I am quite new to SQL, have been learning for ~3 weeks, and have taken a liking to it. Hoping to polish up my skills before beginning to apply to Data Analyst roles.
I've been working with a dummy dvd-rental database and have found myself unable to solve a challenge given to me by a peer. The question was: "what is the most expensive rental for the 4th customer?"
We can see in picture, that based on the nth_customer column, Terrance Roush is the 4th ever customer (he's the 4th ever person to pay). But the issue is that the nth_customer column is actually reporting back the nth order and continues counting to infinity. So the next time Terrance shows up, the nth_customer column will not show '4' (which is what I was hoping to achieve).
Would appreciate any feedback on how to solve this. Thank you in advance.
If "the fourth customer" means the customer who did the fourth rental, you can break the problem down into two - finding that fourth customer, and finding their most expensive rental. Something like this:
SELECT *
FROM payment
WHERE customer_id = (
SELECT customer_id
FROM payment
ORDER BY payment_date
LIMIT 1 OFFSET 3
)
ORDER BY amount DESC
LIMIT 1;
Here I'm finding the ID of the fourth customer in the subquery, using a LIMIT & OFFSET to get just the one record I want. Then in the outer query I'm simply ordering all of that customer's records and taking the one with the biggest amount.
I'm trying to figure out how to come up with a calculation or query to count the number of employees by grade promoted on each pay period.
*count the number of records who's value in grade have increased by pay period.
Sample solution:
Soln:
Year Payroll Period Count
2018 16 2
2019 6 1
2019 10 1
I've tried pivot and queries in access but I think this needs to have an inner join to identify specific employees who got promoted. thanks for the assistance.
code in excel that seems to work but needs to be transferred in access due to the number of records. I think inner join would make this work. =AND(B2<>B3,C2=C3,D3>D2)
Based on EXCEL, you can derive your solution, assuming that your records are in sequence for columns Year, Payroll, Employee & Grade.
Add another column to determine if there is a grade increase for that particular Payroll Period.
For excel cell reference sake, "Year" is in cell A1
Set formula of 1st cell of this column to false
For the next cell in this new column, set it as such:
The above checks if there is a grade increase for that particular Payroll Period.
The explanation of the formula in sequence is as such, 1. Check if year same (A3=A2), 2. Check if Payroll Period is different(B3<>B2), 3. Check if Employee is the same (C3=C2) and finally 4. Check if there is a change in grade (D3=D2).
Copy this formula down to the rest of your range.
Next, you can start to pivot.
Add your pivot table from your table/range with the following
Filter Grade Increase to true and also change the values aggregation of Employee from Sum to Count.
You will get the following:
I would rename Count of Employees to make it more meaningful.
One caveat for the above approach is that if the grade was increased at the beginning of the 1st Payroll Period of the year, the increase won't be captured. For such, you can remove the year check from the formula A3=A2.
Edit:
Doing a bit of research, perhaps you can do
select t1.*, (t1.Grade > t2.Grade) as Grade_Increase
from YourTableName t1 left join YourTableName t2 on
t1.Employee = t2.Employee and
(((t1.Year - 2018)*26) + t1.Payroll_Period) =
(((t2.Year - 2018)*26) + t2.Payroll_Period - 1) -- -1 to get the prior record to compare grades
What the above does is essentially joining the table to itself.
Records that are 'next in sequence' are combined into the same row. And a comparison is done.
This was not verified in Access.
Substitute 2018 with whatever your base year is. I'm using 2018 to calculate the sequence number of the records. Initially I thought of using common table expressions, rank and row_number. But access doesn't seem to support these functions.
I have a query that I am currently using to find counts
select Name, Count(Distinct(ID)), Status, Team, Date from list
In addition to the counts, I need to calculate a goal based on weighted average of counts per status and team, for each day.
For example, if Name 1 counts are divided into 50% Status1-Team1(X) and 50% Status2-Team2(Y) yesterday, then today's goal for Name1 needs to be (X+Y)/2.
The table would look like this, with the 'Goal' field needed as the output:
What is the best way to do this in the same query?
I'm almost guessing here since you did not provide more details but maybe you want to do this:
SELECT name,status,team,data,(select sum(data)/(select count(*) from list where name = q.name)) FROM (SELECT Name, Count(Distinct(ID)) as data, Status, Team, Date FROM list) as q
I want to make a web app for salary management. In which I want to calculate total number of leaves with in a year if there is more than 16 L present in my table than it will count as A absent.
How to make procedure for this?
Any help is appreciated.
Perhaps this could work.
SELECT
EmployeeID,
DaysAbsent=(SELECT COUNT(DISTINCT aDate)FROM aDateTable
WHERE Absent=1 and EmployeeID=Employees.EmployeeID)
FROM
Employess
I am trying to write a report (DB2 9.5 on Solaris) to do the following:
I have a set of data, let's say it's an order table. I want to run a report which will give me, for each month, the number of orders per customer, and their "rank" that month. The rank would be based on the number of orders. I was playing around with the RANK() OVER clauses, but I can't seem to get it to give me a rank per month (or other "group by"). If there are 100 customers and 12 months of data, i would expect 1200 rows in the report, 100 per month, each with a rank between 1 and 100. Let me know if more detail would be helpful. Thanks in advance.
the solution is to use the PARTITION BY clause.
