Calculate Price For Quantity

Feb 20, 2008



Hello all, I have an interesting question about calculating a price in my database for a quantity entered. I have a join table that I store ProductID, SizeID, Quantity and Price. The price for a particular product changes based most often on the quantity ordered. For example, if you order one unit of a widget the price is 10.00, however if you order one dozen units of the same widget the price drop to 9.75 and so on.

Here is a sample of my table....columns are in the order I specified above.

1, 1, 1, 10.00
1, 2, 1, 10.00
1, 3, 1, 10.00
1, 1, 6, 9.90
1, 2, 6, 9.90
1, 3, 6, 9.90
1, 1, 12, 9.75
1, 2, 12, 9.75
1, 3, 12, 9.75
1, 1, 24, 9.50
1, 2, 24, 9.50
1, 3, 24, 9.50
1, 3, 36, 9.30
1, 2, 36, 9.30
1, 1, 36, 9.30


So depending on if my widget is available in certain sizes, the second column, then each product has an price for the size id and quantity at which the price break occurs.

I use this stored procedure to return the price or price range based on the input parameters entered.

CREATE PROCEDURE dbo.sp_GetPrice
@ProductID INT,
@QuantityID INT = NULL,
@SizeID INT = NULL
AS
BEGIN
SET NOCOUNT ON
IF @QuantityID IS NOT NULL AND @SizeID IS NULL -- WE ARE L0OKING FOR A SPECIFIC PRICE BUT DO NOT HAVE A SIZE SPECIFIED
SELECT DISTINCT Price AS 'Price'
FROM join_ProductSizeQuantityPrice
WHERE ProductID = @ProductID
AND Quantity = @QuantityID

IF @QuantityID IS NOT NULL AND @SizeID IS NOT NULL -- WE WANT THE EXACT PRICE FOR THE SIZE AND QUANTITY SPECIFIED
SELECT Price AS 'Price'
FROM join_ProductSizeQuantityPrice
WHERE ProductID = @ProductID
AND SizeID = @SizeID
AND Quantity = @QuantityID
IF @SizeID IS NULL AND @QuantityID IS NULL
SELECT MIN(Price) AS 'Price Range' -- WE ARE LOOKING FOR A PRICE RANGE
FROM join_ProductSizeQuantityPrice
WHERE ProductID = @ProductID
UNION ALL
SELECT MAX(Price)
FROM join_ProductSizeQuantityPrice
WHERE ProductId = @ProductID

END
GO

So everything works great, however, when a user orders an quantity amount like 7, 13, 26 - which is not part of the table - I want to give them the discount available to them for the price break appropriate.

For example if a customer orders 16 widgets of size 2 the price break threshold they have crossed is one dozen, however they have not yet reached the next one which is two dozen. Therefore I want to offer the price associated with one dozen widgets of size id which is: $9.75. Once I have this a simple calculation of this price * 16 units would give me a total but my question is, how do I elegantly design this quantity / right price per unit calculation?

Need Help Updating A Quantity In Db Via A Loop

May 16, 2008

When a user orders an amount of a given product, I want to update the available quantity in my db.  I use a loop to insert each ordered product item and the needed quantity into an ORDERED_ITEMS table (these items are tied to an order record in another table).  The available_quantity is in the STOCK table.  Here is my code.  Can you help me out with how I can achieve this? (I know my queries should be in SP's, but for now while I'm getting everything the way I want it, it's easier to write it directly in my code.)
 Thanks!
 //insert the individual items
string items_to_ship = "";

foreach (GridViewRow rw in GridView1.Rows)
{
if (rw.RowType == DataControlRowType.DataRow)
{
if (((TextBox)rw.Cells[4].FindControl("qtyneeded")).Text != "")
{
int qty = Convert.ToInt32(((TextBox)rw.Cells[4].FindControl("qtyneeded")).Text);
int itm = Convert.ToInt32((rw.Cells[0].Text));

SqlConnection mycn2 = new SqlConnection(myConnectionStr);
SqlCommand myCommand4;
SqlDataReader rdr = null;
int new_qty = 0;
myCommand4 = new SqlCommand
("INSERT INTO SHP_ORDERED_ITEMS (ship_id, item_id, quantity) values(@ship_id,@item_id,@quantity);" + "SELECT item_description, qty_available from shp_stock where item_id = @item_id;", mycn2);

myCommand4.Parameters.Add("@ship_id", SqlDbType.UniqueIdentifier).Value = shipmentID; myCommand4.Parameters.Add("@item_id", SqlDbType.Int).Value = itm;
myCommand4.Parameters.Add("@quantity", SqlDbType.Int).Value = qty;

myCommand4.Connection.Open();

Deduct Quantity Of SKU From One DB To Next Database

Jan 3, 2013

currently we have some shipping software that has a mqsql database locally.There are filters on the program and when an item is shipped from our warehouse it goes into a filter "Shipped".We have a SKU and also quantity for the product.

Now we have an inventory program that also has a mqsql database,this has the same SKU as the shipping software database.what we hope to do is when an SKU is shipped in our software program(ie it Goes into the "Shipped" folder),it will deduct the quantity from the adjacent SKU in the inventory program database.

Note that the 2 databases are independent from each other but would like them to be in effect linked to each other.

MAX Date Dependent On Quantity

Aug 20, 2013

I am trying to query only the Max date dependant on quantity

Create Table dbo.TestParts
(Part char(30), Desc1 char(50), Desc2 char(50));
Create Table dbo.TestStructure
(Model char(30), Part char(30), EDATE smalldatetime, QtyPer float);
GO
Insert INTO dbo.TestParts Values('101111','Widget A', 'Batteries Not Included'),

[Code] ....

Looking for a return of:

PART Description EDATE QtyPer
101112 Widget B ..... 2012-12-03 3
101113 Widget C ..... 2012-12-03 5
101114 Widget D ..... 2012-12-01 1

Widget A should not show because the last date the qty was changed to Zero

Closest that I have come..........(which is pulling the part 101111 which should be incorrect)

Select ts.Part, RTRIM(tp.Desc1) + ' ' + RTRIM(tp.Desc2) as Description,
ts.EDATE, ts.QtyPer
FROM testing.dbo.TestStructure ts
Inner Join (Select Part,MAX(EDATE) as Date

Real Time Quantity Update Using Triggers

Aug 25, 2001

Hi
There are 2 databases db1 and db2 on SQL server 7 with tables 1 and 2 respectively.
Both these tables have a field called Quantity. IF quantity gets updated in table 1 then that change should be immediately reflected in table2.
I though an update on table1 would serve the purpose but this trigger doesn't seem to be working however there are no errors during the syntax check.
The code for the trigger that i have used on table 1 is as below
CREATE TRIGGER [Qty_UPDATE] ON [Table1]
FOR UPDATE
AS
IF UPDATE (Qty)
BEGIN
UPDATE db2.dbo.table2
SET db2.dbo.table2.qty = qty
END
Please help
Thanks in advance
