Display Only The Listing With The Lowest Price (was Need A Little Help Here.....)
Mar 13, 2006
I have a little problem that I just haven't been able to solve. I don't think it is very difficult but I can't seem to make it work. Here's the scenario:
I have a database with the following values:
Model Make Price
DA1100 GTN$88.00
DA1100 GTN $100.00
DA1000 GBN$110.00
DA668 GTN$100.00
DA880 GTN$200.00
In this case DA1100 is listed twice with 2 different prices. I only want to display the one with the lowest price. So the result I want is:
Model Make Price
DA1100 GTN$88.00
DA1000 GBN$110.00
DA668 GTN$100.00
DA880 GTN$200.00

I have to add the unit price on the order acknowledgement for products on our shelf.
Each product has different price breaks stored in a table called MaterialUnitCost.
I don't know how to pull the correct price based on the order quantity.
Let's say the customer orders 200 pieces,
I sell 1 pcs @ $20
50 pcs @$15
200 pcs @$10.
My order acknowledgement should pull a unit price of $10, but it pulls $20 instead, because in my select statement I have
select materialunitcost.unitcost.
I thought I should do a loop or use the row_number function, but I am new to SQL, and I never used any of these two.

I am developing basket and need a simple way to get price x quantity + total price.
I get back a recordset which has a varying number of items, each item has a price and quantity. Using
SELECT ((productprice)*(productquantity)) AS subtotal, product name, productid
I don't know how to add all subtotals to get a total, I have tried putting in SUM but but cant get it to work.
Any help would be well appreciated.

OK, this should be an easy one but my brain isn't quite working right now.
I have a table, we'll call Table1 like so:
ProductID Supplier Cost
12345 A 14.50
12345 B 13.49
12345 C 12.00
43222 A 15.00
43222 B 15.21
43222 C 13.99
12312 B 14.00
15421 A 21.99
15421 C 20.00
And I want to Get the name of the Supplier with the Lowest cost,
I know I can go like:
SELECT ProductID, MIN(Cost) FROM Table1 GROUP BY ProductID
and get the lowest cost, but what would be the most effiecent way to get all three fields returned by the query? I need the ProductID, Supplier and Cost.
Thanks,

Hi, this seems to be an easy question but I can't find a quick answer to it.
I have an asp page that communicates with a database and I want the following example to work...
Insert 5 records into the DB with primary keys 1-5.
Remove record with key number 2.
Now, if I insert a new record I want it to take the smallest available key number (in this case number 2). This will save space in the database and keep the key numbers from increasing forever.
Does auto increment work like this?
If not, how do I do it?
Thanks for any replies!

Im having trouble finding a solution to comparing columns to find the lowest value.
Example
Row 1
COL 1 = 10
COL 2 = 20
COL 3 = 60
COL 4 = 5
COL 5 = 35
I would want to return 5.
I tried to write a case statement such as below but am unable to use Logical Operators.
WHEN C1 <= C2 and C1<= C3 THEN C1
WHEN C2 <= C3 THEN C2
ELSE C3
any help would be great.
Thanks,
Nick

I'm using sql express 2005. I need help with buliding a view.
I'm trying to join two tables and then, if duplicate ID's exist, retrieve the row with the lowest value in a specific column.
For instance:
TableHousehold:
ID Name Status
001 The Smith€™s A
002 The Jone€™s A
003 The Adam€™s A
004 The Grant€™s A
TableResidents
Pk HouseholdID ResidentID Name Gender
1 001 1 Mary Smith F
2 001 2 Jason Smith M
3 001 3 Rachel Smith F
4 002 1 Mike Jones M
5 002 2 Sara Jones F
6 003 2 Erik Adams M
The resident ID is auto increment and assigned by the server. It is possible for resident 1 for each household to have been deleted. It is also possible that a household does not contain any residents. Therefore, I wish to join these tables and return this:
ID HouseHoldName Status ResidentName Gender
001 The Smith€™s A Mary Smith F
002 The Jone€™s A Mike Jones M
003 The Adam€™s A Erik Adams M
004 The Grant€™s A null null
There are other columns in both tables that I will want to join, but for simplicity, the above example illustrates my need.
I was able to accomplish this by creating two views. But I€™d like to try and do this in one.

Let's say I have a result set (records) containing numbers such as:01239162145100101102103104105106How might someone write a procedure to get the next lowest number inthis sequence? In this case it would be: 4. Some combination ofSelect, Min & When, I am sure, but it escapes me at the moment.Thoughts? Thanks...

I am attempting to only query the lowest year, and month from my entire production database. I am using the following query and when I do it individually it will bring back the lowest year but also with additional years. How can I remove those other years so I can only query the lowest year and month from the entire database?
Code:
select distinct RRCID, MIN(YEAR)as YEAR, MONTH
from Gas_Prodv1
where RRCID = 1221376
group by RRCID, MONTH
order by YEAR, MONTH

ID (PK), userID (FK), from [Datetime], to[datetime], type [int] , value [nvarchar]
Conditions
I want to select the column "to" which is a datetime-column for all users within the table.
One user can have multiple registered rows in "mytable", so I want to select the row that contains the newest "from" date.The newest "from"-column for a specific user is where I am struggling... Because if the "to"-column of any of the registered rows by the current user is equal to the newest "from -1 day" column for the user, I want to select the second newest from-date.
Code:
//Handwritten
DECLARE @from DATETIME //Current Selected datetime [the newest of the current user doing the query]
DECLARE @id INT //userID
DECLARE @tbl TABLE (from datetime, userid int)
[code]....
But for user ID 201 [all users with Type = 1], I need to run through some more code, to figure out which date we want... Which date do I want? The "from"-date that is the newest, but if "to" is just 1 day before "from", I want to select the "from" at that row instead... Example with numbers [integers] instead of Date:
Code:
From - To
5 8
10 15
16 20
I want to select "10" in the from column as the maximum "from"-integer, and not 16. Because in the "To" column we have a match in the "from" column on the condition "To + 1" [15+ 1 == 16], so then I want the "from" value where "To" equals 15, which is 10. The top row I do not want, because the difference between From and To [10 - 8 is larger than 1]...
This means that the Image shown... I am first selecting the "1", then I do some checks, if the "to" for the user is 1 day earlier than the MAX(from) I grab a new "from" value...
Code:
SELECT MIN (t1.from) FROM table as t1
WHERE
t1.from IN
(
SELECT t2.to+ 1 FROM table as t2
WHERE t2.userID = @id
)

Hello all, I have a question. I have two tables, one called Products which is comprised of various lookup values for IDs. The sceond table is a join table where I enter through a tool that I built another series of lookup IDs for Product, Size, Color, Quantity and Price. Each product in the join table can have multiple entries because there is not one price for each product. Instead, based on the product size, color there are price breaks at certain quantities - for example if someone orders one dozen widgets then the price will be one amount, while if they order two dozen they will get a different price.
Here is an example:
Product table
ProductID ProductName Description
1 Widget This is a widget description...
ProductPrice tbl
ProductID ColorID SizeID QuantityID Price
1 1 1 1 10.00
1 1 1 2 9.50
etc....
Quantity tbl
ID Description
1 12 - or one dozen
2 24
So what I want to do is get a complete list of products with the MAX price for each product returned. This will be displayed on a page where I will have the Product Name, Description, etc and the Price will state something like 'Starting at $10.00'
Here is what I have so far but I am not getting any results....
SELECT p.ProductID,
p.ProductName,
pc.ProductCategoryName,
p.ProductImageID,
SUBSTRING(p.Description, 1, 150) + '...' AS Description,
(SELECT DISTINCT MAX(Price)
FROM ProductColorSizeQuantityPrice
WHERE ProductId = 1) AS 'Price'
FROM Products p
INNER JOIN ProductColorSizeQuantityPrice pcs
ON pcs.ProductID = p.ProductID
INNER JOIN ProductCategory pc
ON pc.ProductCategoryID = p.ProductCategoryID
The area highlighted in blue is what I am trying to do logically but this is not getting any results. If I removed this section I get all the fields I want but I need to include this price. Any ideas?

I have just been running a query which I was planning on improving by removing a redundant GROUP BY (there are about 20 columns, and one of the columns returned is atomic, so will mean that the "group by" will never manage to group any of the data) but when I modified the query to remove the grouping, this actually seems to slow the query, and I can't see why this would be the case.
Both queries return the same number of rows (69000), as I expected, and looking at the query plan, then they look nearly identical, other than at the start, there is a "stream aggregate" and "sort" being performed. The estimated data size is 64MB for the non-grouped query (runs in 6 min 41 secs), vs 53MB for the aggregated query (runs in 5 min 31 secs), and the estimated row size is smaller when aggregated.
Can rationalise this? In my mind, the data that is being pulled is identical, plus there is extra computation for doing an unnecessary aggregation, so the aggregated query should be unquestionably slower, but the database engine has other ideas; it seems to be able to work more quickly when it needs to do unnecessary work :) Perhaps something to do with an inefficient query plan for the non-aggregated query? I would have thought looking at the actual execution plan might have made this apparent, but both plans look very similar.
Edit: More information, the "group by" query had two aggregations on it, a count of one of the columns, and an average of another one. I changed this so that it was just "1" instead of the count, and for the average, I changed it to be the expression within the average aggregate, since the aggregation effectively does not do anything.

Hello Group,
I'm still a bit new to T-SQL and am wondering how to get various LOWEST values from a table, rather than TOP values. There does not appear to be a keyword opposite of TOP in T-SQL.
My real problem is this: I know how to get the 2nd highest value, third highest value, etc...but how does one get the 2nd lowest value, third lowest value, etc?
Would anyone be able to help?
Thanks!!

I plan on purchasing a new production server that will be running sql server and IIS under the dotnet framework/Windows Server 2003. It will be doing the following-
Running 6 or 7 customer service web applications that will operate as asp.net apps w/vb.net. These are database intensive applications but run a relatively light load with only 20 or so users accessing.
Running the 'customer service' portion of our web site that customers will use to access their account info, historical orders, order status, etc. These are also asp.net pages and are modestly database intesive. If I had to make a WAG, I would say that maybe 50 users on average to say 100 peak using these pages.
I plan on buying a single Xeon with say 2 GB of RAM, I'm not sure about the hard drives but something with suds.
So my question after that long tome is what's the tradeoff between RAM and extra processor. Given a fixed budget for the server, if I were to ask for additional funds I'm not sure if I should invest in additional processor or more RAM.
And also, I'm not sure about running the server for both internal and external applications. Obviously the internal apps could take a hit if things got busy externally. Is there any kind of best practice that advises against this.
Any ideas?

I've got a fairly large hierarchy table and I'm trying to put together a query to find the lowest level descendants of the hierarchy. I think there must be some way to use the "Breadth-first" approach that's stated in the MSDN technet sites about SQL Server HierarchyID but i'm not sure how to write the necessary T-SQL to traverse that. I know I can get all the descendants of a parent node like this
SELECT *
FROM AdventureWorks2012.HumanResources.Employee
WHERE OrganizationNode.IsDescendantOf(@ParentNode) = 1
However, this query returns all levels for that parent's branch. If I just wanted list of employees that were at the lowest level of the branch(es) for this parent node, how would I do this?
