I have 3 tables
items,
item_units,
order_items
First table items has the list of items that can be ordered.
Second table item_units has units for the items as well as the amount of those items in this unit
Third table has items that were ordered... ie... item_code , unit, qty
Here are the columns for items
[item_code]
,[desc]
Here are the columns for item_units
,[item_code]
,[unit]
,[amount]
,[price]
,[default_sprd_sht]
Here are the columns for order_items
,[order_id]
,[item_code]
,[item_desc]
,[unit]
,[qty]
,[price]
Note the [default_sprd_sht]. This field is a boolean. If it's set to true this unit is never put into order_items table. This field will be used as calculation field.
For example:
If 1 customer orders 2 6 packs of bread and another orders 3 dozens of bread, the baker needs to know how many pans of bread to make.
Now a 6 pack unit has 6 breads as amount, meaning 2 * 6 = 12. And a dozen unit has 12 breads.. 12 * 3 = 36. A pan bread unit has 20 breads. So i need to add up all the bread units amounts and divide them by the pan amount like so
((2*6) + (12 * 3)) / 20 = 2.4
So the first thing I did to create a report for the baker was
Create a group for order_items.item_code and then order_item.unit.
This needs to be done since the same item and unit cobination will be repeated in different orders. The baker needs to see how many bagels or breads he needs to bake in total.
in the order_item.unit group header I created a formula field that multiplies the order_item.unit by item.amount
Sum ({order_items.qty}, {order_items.unit}) * {items_units.amount}
That was easy.
But I aslo need to group all order items if there exists a record in the items_units with the same item_code and with [default_sprd_sht] set to true
This would look like so
(Sum ({order_items.qty}, {order_items.unit}) * {items_units.amount}) / (get amount for unit with the same item_code and [default_sprd_sht] = 1)
I have two problems accomplishing this.
How to check if this order item has a unit with same item_code and
[default_sprd_sht] = 1?
How to further group order items only if there is a unit with same
item_code and [default_sprd_sht] = 1?

I have the following problem.
I need all the products in a table and at the same time put the sum of the quantities sold of each product.
I need to see each product in the product table with the total sum of sales, according to the date range.
If there is no sales record in that range, it must be zero.
My query is as follows, but it doesn't work.
Product Table : sto_producto
Product sales movement table: sto_movdet
SELECT
sto_producto.pro_codprod AS cod_product,
sto_producto.pro_desc AS name_product,
sum(sto_movdet.mvd_cant) AS total_sale,
AVG(sto_movdet.mvd_costo) AS cost_product_sale
FROM sto_producto
INNER JOIN sto_movdet ON (sto_producto.pro_codprod = sto_movdet.mvd_codprod)
WHERE mvd_fecha BETWEEN '2020301' and '20200716'
GROUP BY pro_codprod, pro_desc
I expect a result similar to
cod_product name_product total_sale cost_product_sale
0004 mousered 45 $ 2.355
0071 pc laptop 0 $ 1.000
How can I indicate multiple records with the same Invoice number, but a different Sales Person ID? Our commissions can be split into multiple Salespeople, so there can be two different Salespeople per an invoice.
For example:
Grouped by: Sales Person ID (No Changing this option)
These records are in the Group Footer.
Sales Person ID: Invoice: Invoice Amt: Commissions: (Indicator)
4433 R100 20,000 3,025 * More than one record on the same invoice with a different sales person
4450 R096 1,987 320
4599 R100 20,000 3,025 * More than one record on the same invoice with a different sales person
4615 R148 560 75
4777 R122 2,574 356
If your report has less than 1000 invoices, you may try something like this.
This will return true when a second ocurrence of the invoice shows up. Then you can make something like set the row background do red.
Global NumberVar Array invoices;
numbervar nextIndex := count(invoices) + 1;
if nextIndex <= 1000 and not ({Result.InvoiceNumber} in invoices) then (
redim invoices [nextIndex];
invoices[nextIndex] := {Result.InvoiceNumber};
true;
)
else false;
If you want to detect the first occurrence, you will need something more sophisticated.
I think a SQL Expression Field would be a good way to achieve the result you want. You already have an InvoiceNo in each row of data. You just need a SQL Expression Field that uses that INvoiceNo to execute a query to count the number of salespersons who get a commission.
Something along the lines of:
(
Select Count(Sales_Person_Id)
From [Table]
Where [Table].InvoiceNo = InvoiceNo
)
This will return an integer value that represents the number of salespersons who are associated with one invoice. You can either drop the SQL Expression Field in your Indicator column, or write some other formula to do something special.
How can I write a calculation field in a table that outputs '1' if there are other (related) records in the same table that meet a given set of criteria and '0' otherwise?
Here's my problem explained in more detail:
I have a table containing 'students' and another containing 'exam results'. The 'exam results' table looks like this:
StudentID SubjectID Level Result
3234 1 2 A-
3234 2 4 B+
4739 1 4 C+
A student can only pass a Level 4 exam in subject 2 if they have also passed a Level 2 exam in subject 1 with a B+ or higher. I want to define a field in the 'students' table that contains a '1' if there exists an exam result belonging to the right student that meets these criteria and a '0' otherwise.
What would be the best way to do this?
Let us take an example of a Results table where the results are also calculated as a numeric value, e.g.
StudentID SubjectID Level Result cResultNum
3234 1 2 A- 95
3234 2 4 B+ 85
4739 1 4 C+ 75
and an Exams table with the following fields (among others):
RequiredSubjectID
RequiredLevel
RequiredResultNum
Given these, you can construct a relationship between Exams and (another occurrence of) Results as:
Exams::RequiredSubjectID = Results 2::SubjectID
AND
Exams::RequiredLevel = Results 2::Level
AND
Exams::RequiredResultNum ≤ Results 2::cResultNum
This allows each exam record to calculate a list of students that are eligible to take that exam as =
List ( Results 2::StudentID )
I want to define a field in the 'students' table that contains a '1'
if there exists an exam result belonging to the right student that
meets these criteria and a '0' otherwise.
This request is unclear, because there are many exams a student may want to take, and a field in the Students table can calculate only one result.
You need to do a self-join in the table for the field you want to check, for example:
Exam::Level = Exam2::Level
Exam::Student = Exam2::Student
And for the "was passed" criteria I think you could do an "If" on the calculation like this:
If ( Last(Exam2::Result) = "D" and ...(all the pass values) ; 1 ; 0 )
Edit:
It could be just with the not pass value hehe I miss that it will be like this:
If ( Last(Exam2::Result) = "F" ; 0 ; 1 )
I hope this helps you.
I have a report which has essentially
Order
OrderDetail 1
OrderDetail ..
OrderDetail n
These details can have parts and/or labour costs associated with them.
Currently, I group based on OrderId and then have the OrderDetail information in the details section of the report. This works perfectly.
However, now I need to group the Orders based on two criteria OrderType and LabourCost of the entire Order. I have put together a quick formula to determine order.
if(Sum({order.Labour}, {order.OrderId})> 0) then
if({order.type} = "type1") then 1 else 2
else
if({order.type} = "type1") then 3 else 4
Basically, if it should be sorted based on labour then on type. (the Sum({order.Labour}, {order.OrderId}) sums the labour grouping based on the orderid)
However when I go to the Group Expert and add the group by field to my formula and then preview my report it spins (I cancelled the preview after a minute). If I remove the Sum portion of the formula then it takes less than a second.
Is there a way to order this report?
How I would approach it:
First, create a sql-expresssion field that calculates the labor total for each order:
// {%TOTAL_LABOR}
(
SELECT Sum(Labour)
FROM OrderDetail
WHERE OrderId=Order.OrderId
)
Next, create a formula field:
// {#OrderGroup}
if({%TOTAL_LABOR}> 0) then
if({order.type} = "type1") then 1 else 2
else
if({order.type} = "type1") then 3 else 4
Finally, create a new group, based on the formula field, ensuring that it groups before the order group. You can suppress the group's header and footer if desired.
I want to get grouped data from a table in sqlite. For example, the table is like below:
Name Group Price
a 1 10
b 1 9
c 1 10
d 2 11
e 2 10
f 3 12
g 3 10
h 1 11
Now I want get all data grouped by the Group column, each group in one array, namely
array1 = {{a,1,10},{b,1,9},{c,1,10},{h,1,11}};
array2 = {{d,2,11},{e,2,10}};
array3 = {{f,3,12},{g,3,10}}.
Because i need these 2 dimension arrays to populate the grouped table view. the sql statement maybe NSString *sql = #"SELECT * FROM table GROUP BY Group"; But I wonder how to get the data from the resultset. I am using the FMDB.
Any help is appreciated.
Get the data from sql with a normal SELECT statement, ordered by group and name:
SELECT * FROM table ORDER BY group, name;
Then in code, build your arrays, switching to fill the next array when the group id changes.
Let me clear about GroupBy. You can group data but that time its require group function on other columns.
e.g. Table has list of students in which there are gender group mean Male & Female group so we can group this table by Gender which will return two set . Now we need to perform some operation on result column.
e.g. Maximum marks or Average marks of each group
In your case you want to group but what kind of operation you require on price column ?.
e.g. below query will return group with max price.
SELECT Group,MAX(Price) AS MaxPriceByEachGroup FROM TABLE GROUP BY(group)
