I have been tasked to match a payment file from a bank that has invoices/payments listed on a text file I have imported into a table called Bank. I need to match the invoices to the project/projects that are associated with the invoices - call this table Invoices - which contains every invoice and project we have every had. I want to match the invoices (from Bank) to the project or multiple projects (from Invoices) to another table - called Report - so I can reconcile the payment file. I can get the correct results from Bank and Invoices with the following query
SELECT invoice
FROM Invoices INV
INNER JOIN Bank as BANK
ON INV.Invoice = BANK.Invoice_Number
The Bank file has 100 invoices and I get 169 invoices on this query. But when I try and do and update or insert
Update Report
set Invoice_Num =
(SELECT invoice
FROM Invoices INV
INNER JOIN Bank as BANK
ON INV.Invoice = BANK.Invoice_Number)
I get 0 rows updated.
I have tried to copy the Bank table to the Report table with
Insert into Report(Invoice_Num)
select Invoice_Number from Bank
but can't figure out how to account for the projects that have duplicated invoices when they are found. Of course I might be going at this entirely wrong and someone has a better way entirely.
Thanks!
Does your Report table have anything in to start with? If not, your UPDATE statement will update 0 rows, because there are 0 rows there to update. (Also, with your code as it stands, note that it would update every entry there to have the same, indeterminate value; I don't think that's what you intend.)
If you just want to copy the invoice numbers from Bank to Report, but leave out any duplicates, then your final bit of SQL just needs a DISTINCT added to do that:
Insert into Report(Invoice_Num)
select DISTINCT Invoice_Number from Bank
If you're trying to put in only invoice numbers from Bank that also match Invoice, then your first bit of code almost works, but needs to be an INSERT, not an UPDATE:
INSERT INTO report (invoice_number)
SELECT invoice
FROM Invoices INV
INNER JOIN Bank as BANK
ON INV.Invoice = BANK.Invoice_Number
Again, if you're also dealing with potential duplicates invoice numbers you only want in Report once, make that a SELECT DISTINCT to avoid them.
I have a SQL Server database with a table dbo.sales with 7 columns.
First column contains different sales person names, on column 2 to 6 other information, on column 7, sales average.
Question: what I need is a query to get all sales person details (all seven columns in Excel) if their sales average is more than 60% between a given date.
For example: in my database, I have data from 01/05/2016 to 31/05/2016, if I enter a period in my Excel sheet between 25/05/2016 to 31/05/2016 and my required average for ex. 60% (should be changed as per my need), then I need all the sales person details who continuously have sales average of more than 60% between 25 to 31st May 2016.
If a sales man average was dropped below 60% on 28th May, then I don't want to see him on my report. In simple words, I need all sales person who continuously hitting 60% or more on average sales within my search period.
Not sure if the sales period date is within the table, but if it is, that query should work for you:
;WITH PeriodSales as (
SELECT * FROM Sales
WHERE SalseDate between #StartDt and #EndDt)
SELECT * FROM PeriodSales
WHERE SalesPerson not in (
SELECT SalesPerson FROM PeriodSales
WHERE CASE WHEN IsNumeric(salesavg) = 1
THEN CAST(salesavg as Decimal) ELSE 0 END <= 60.
);
I have 2 database tables called Spend, and VendorSpend. The columns used in the Spend table are called VendorID, VendorName, RecordDate, and Charges. The VendorSpend table contains VendorID and VendorName but with distinct data (one record for each unique VendorID). I need a simple way to add a column to the VendorSpend table called Aug2015, this column will contain the SUM of each Vendor's charges within that month time period. It will be calculated based on this query:
Select Sum(Charges)
from Spend
where RecordDate >= '2015-08-01' and RecordDate <= '2015-08-31'
Keep in mind this will need to be called whenever new data is inserted into the Spend table and the VendorSpend table will need to update based on the new data. This will happen every month so actually a new column will need to be added and the data be calculated every month.
Any assistance is greatly appreciated.
Create a user-defined function that you pass a VendorID and Date to and which does your SELECT:
Select Sum(Charges)
from Spend
where VendorID=#VendorID
AND DATEDIFF(month, RecordDate, #Date) = 0
Now personally, I would stop right there and use the function to select your data at query time, rather than adding a new column to your table.
But treating your question as academic, you can create a computed column called [Aug2015] in VendorSpend that passes [VendorID] and '08/01/2015' to this function and it will contain the desired result.
Background: In SQL Server, my database table only has three columns:
DataID (PK, bigint)
ProductName (Nchar20)
Price (float)
Every day it will automatically insert about 5000+ rows of data into this table. Later on this table may add more columns like AdjustedPrice (float), Discount (float)...
Question: I know I should probably make ProductName as FK to another table (ProductNameTable with ProductID (PK,int) and ProductName (Nchar), but what about the price (float)? Price are depends, could range to 100 - 1000, should I make it FK to another table or just leave it alone in the table?
Any advice from DBA? Thank you sooooo much.....
Yeah. No. Price is an atmic element. But my advice would be to get a copy of the Data Model Ressoure Book volume 1 - it discusses database schemata for pricing engines. A good read.
I want to create a small database for my inventory but I have some problems on picking a structure. The inventory will be updated daily at the end of the day.
The problem I am facing is the following.
I have a table for my products, having an
id, name, price, quantity.
Now I have another table for my sales, but there is my problem. What kind of fields do I need to have. At the end of the day I want to store a record like this:
20 product_x $ 5,00 $ 100,-
20 product_y $ 5,00 $ 100,-
20 product_z $ 5,00 $ 100,-
20 product_a $ 5,00 $ 100,-
-------------------------------------------------
$ 400,-
So how do I model this in a sales record. Do I just create a concatenated record with the product id's comma separated.
Or is there another way do model this the right way.
This is a model which supports many aspects,
Supports Sites, Locations and Warehouses etc.
Supports Categorization and Grouping
Support Generic Product (Ex. "Table Clock" and specific product "Citizen C123 Multi Alarm Clock" )
Also support Brand Variants (by various manufacturers)
Has CSM (color / size / model support) Ex. Bata Sandles (Color 45 Inch Blue color)
Product Instances with serials (such as TVs , Refrigerators etc.)
Lot control / Batch control with serial numbers.
Pack Size / UOM and UOM Conversion
Manufacturer and Brands as well as Suppliers
Also included example transaction table (Purchase order)
There are many other transaction types such as Issues, Transfers, Adjustments etc.
Hope this would help. Please let me know if you need further information on each table.
Cheers...!!!

I'd have a table with a row per item per day - store the date, the item ID, the quantity sold, and the price sold at (store this even though it's also in the product table - if that changes, you want the value you actually sold at preserved). You can compute totals per item-day and totals per day in queries.
Tables:
create table product (
id integer primary key,
name varchar(100) not null,
price decimal(6,2) not null,
inventory integer not null
);
create table sale (
saledate date not null,
product_id integer not null references product,
quantity integer not null,
price decimal(6,2) not null,
primary key (saledate, product_id)
);
Reporting on a day:
select s.product_id, p.name, s.quantity, s.price, (s.quantity * s.price) as total
from product p, sale s
where p.id = s.product_id
and s.saledate = date '2010-12-5';
Reporting on all days:
select saledate, sum(quantity * price) as total
from sale
group by saledate
order by saledate;
A nice master report over all days, with a summary line:
select *
from (
(select s.saledate, s.product_id, p.name, s.quantity, s.price, (s.quantity * s.price) as total
from product p, sale s
where p.id = s.product_id)
union
(select saledate, NULL, 'TOTAL', sum(quantity), NULL, sum(quantity * price) as total
from sale group by saledate)
) as summedsales
order by saledate, product_id;
Try modelling your sales as a transaction - with a "header", i.e. who sold to, when sold, invoice # (if applicable), etc. and "line items", i.e. 20 * product_x # $5 = $100. The safest approach is to avoid relying upon prices etc. from the products table - as these will presumably change over time, and instead copy much of the product information (if not all) into your line item - so even when prices, item descriptions etc. change, the transaction information remains as was at the time the transaction was made.
Inventory can get quite complex to model. First you need to understand that you need to be able to tell the value of the inventory onhand based on what you paid for it. This means you cannot rely on a product table that is updated to the current price. While you might want such a table to help you figure out what to sell it for, there are tax reasons why you need to know the actual vlaue you paid for each item in the warehouse.
So first you need the product table (you might want to make sure you have an updated date column in this, it can be handy to know if your prices seem out of date).
Then you need a table that stores the actual warehouse location of each part and the price at purchase. If the items are large enough, you need a way to individually mark each item, so that you know what was taken out. Usually people use barcodes for that. This table needs to be updated to record that the part is no longer there when you sell it. I prefer to make the record inactive and have a link to my sales data to that record, so I know exactly what I paid for and what I sold each part for.
Sales should have at least two tables. One for the general information about the sale, the customername (there should also be a customer table most of the time to get this data from), the date, where it was shipped to etc.
Then a sales detail table that includes a record for each line item in the order. Include all the data you need about the part, color, size, quantity, price. This is not denormalizing, this is storing historical data. The one thing you do not want to do is rely on the prices in the product table for anything except the inital entry to this table. You do not want to do a sales report and have the numbers come out wrong becasue the product prices changed the day before.
Do not design an inventory database without consulting with an accountant or specialist in taxes. You also should do some reading on internal controls. It is easy to steal from a company undetected that has not done their work on internal controls in the database.
I think you need a table with fields showing the transaction properties per customer
OR
a table with fields - date, product(foreign), quantity - this way you'll have no problem with new products
Try multiple tables with links
table_products
id
name
table_product_sales
id
product_id
quantity
price_per
transaction_time AS DATETIME
SELECT table_product_sales.*, table_product.name
FROM table_product
JOIN table_product_sales
ON table_product_sales.product_id = table_product.id
GROUP BY DATE(transaction_time)
Haven't tried it but will something like that work? That allows you to keep each transactions separate so you can query things like average number sold per sale, total sold per date, total sales each day, etc.
