I'm trying to solve this problem but can't seem to figure out how to
start. I would like to create a rating system where people can vote
(1-5 stars) on randomly displayed items. The randomly displayed items
should either have very high ratings OR a very low number of ratings.
For example, only return items in the top 20th percentile *OR* items
with fewer than 5 votes.
The question is, how would I write an SQL query to return such a
result? Is it even possible? Should this be handled by my application
rather than the database?
For simplicity, let's assume I have the following table:
Any help or pointers in the right direction would be greatly
appreciated. My apologies in advance if the solution is obvious and I
am clearly missing the point ;-)
(SELECT MAX(TotalRating)FROM Recipe) AND published = 1 AND ReleaseDate <= @CurrentDate AND ExpireDate > @CurrentDate
This doesn't work good when the recipe having max total rating is not published & expired. I guess I need to first filter the recipes which are published & unexpired and then select the recipe having max total rating. But I don't know how to do that. Could anyone of you please help me doing this ?
I am looking to order this table by CardNo and then TransNo but i only want the query to display the record with the highest TransNo for each CardNo. In other words discard the records with the lower TransNo for each CardNo.
My desired result should hopefully look something like this:
Hi: I'm try to create a stored procedure where I sum the amounts in an invoice and then store that summed amount in the Invoice record. My attempts at this have been me with the error "The multi-part identifier "items.TAX" could not be bound"Any help at correcting my procedure would be greatly appreciate. Regards,Roger Swetnam ALTER PROCEDURE [dbo].[UpdateInvoiceSummary] @Invoice_ID intAS DECLARE @Amount intBEGIN SELECT Invoice_ID, SUM(Rate * Quantity) AS Amount, SUM(PST) AS TAX FROM InvoiceItems AS items GROUP BY Invoice_ID HAVING (Invoice_ID = @Invoice_ID) Update Invoices SET Amount = items.Amount WHERE Invoice_ID =@Invoice_IDEND
I am struggling to come up with a set-based solution for this problem (i.e. that doesn't involve loops/cursors) ..A table contains items (identified by an ItemCode) and the set they belong to (identified by a SetId). Here is some sample data:
SetIdItemCode 1A 1B 24 28 26 310 312 410
[code]....
You can see that there are some sets that have the same members:
- 1 and 10 - 2 and 11 - 7, 8 & 9
What I want to do is identify the sets that have the same members, by giving them the same ID in another column called UniqueSetId.
I'm having an issue creating a report that can group & sum similar items together (I know in some ways, the requirement doesn't make sense, but it's what the client wants).
I have a table of items (i.e. products). Â In some cases, items can be components of another item (called "Kits"). Â In this scenario, we consider the kit itself, the "parent item" and the components within the kit are called "child items". Â In our Items table, we have a field called "Parent_Item_Id". Â Records for Child Items contain the Item Id of the parent. Â So a sample of my database would be the following:
Item's 2 & 3 are child items of "Kit A", Item 5 is a child item of "Kit B" and Item 6 is just a stand alone item.
So, in my report, the client wants to see the SUM of both the kit & its components in a single line, grouped by the parent item. Â So an example of the report would be the following:
Name | Available Qty -------------------------- Kit A | 15 Kit B | 25 Item 4 | 100
Hi, I am a newbie, this is my first post (please go easy).
Iam at the moment trying to set up a query for someone looking for a property on an estate agents website.
From a drop down menu, the user can: select an area (where they may like to live) from a list of areas. select an amount of bedrooms from a list of bedrooms select a minimum price from a list of prices select a maximum price from a list of prices.
The query I worked out for this is as follows: $data = mysql_query("SELECT * FROM property WHERE area like '$area' and bedrooms like '$bedrooms' AND price BETWEEN '$min_price' AND '$max_price'") or die(mysql_error());
This seems to work fine and shows all the properties that meet the criteria onto my webpage.
However, I then thought, someone may not care which area they live in and want to see all properties in all the areas, so I decided to add the option 'All areas' to my 'areas' list, I then did the same for the other lists, eg 'all bedrooms' option to my bedrooms list and so on.
I am now trying to write a query that incorporates where the 'all..' option is selected and have become very stuck! Can someone set me off in the right direction for this. I hope that makes sense?!?!
Let's say I have the following table:entry product quality1 A 802 A 703 A 804 B 605 B 906 C 807 D 808 A 509 C 70I'm looking for a way to find the average "quality" value for aSEQUENTIAL GROUPING of the same Product. For exmple, I need anaverage of Entry 1+2+3 (because this is the first grouping of the sameproduct type), but NOT want that average to include row 8 (which isalso Product A, but in a different "group".)I'm sure it can be done (because I can describe it!), but I'll be amonkey's uncle if I can figure out how. I would imagine it wouldinvolve some sort of running tally that references the next record asit goes... to see if the product type has changed. Perhaps use of atemporary table?Muchas gracias!!Cy.
I've never been the most articulate person in the world, so i thoughthe best way to illustrate the script I am looking for help with, is toprovide you with two tables and the results I require.Table 1ProductName1ProductName2QtyAAAA-12BBBB-13CCCC-14Table2ProductNameQtyAA2BB-13DD6Desired ResultsProductNameQtyDD6Regards,Ciarán
Name Qty Location ----------------------------------- Item A 2 Warehouse 1 Item A 5 Warehouse 2 Item B 3 Warehouse 1 Item C 1 Warehouse 1 Item B 6 Warehouse 2
How is the sql command/query/store procedure to generate result like this?
Name Qty ----------------- Item A 7 Item B 9 Item C 1
I'm not sure if this is even possible but can i pull out rows from two tables (that have a one-to-many relationship) but only if they satisfy a few conditions.
tblWine tblSources ID Name ID WineID Source Price Status ----------------- ----------------------------------------- 1 Le Dome 1 1 Smith 100.00 IB 2 Teyssier 2 1 Jones 110.00 IB 3 Muscat 3 1 Hill 100.00 DP 4 2 Smith 135.00 DP 5 2 Hill 125.00 DP
I only want to pull out row that contain the cheapest wine for their status. So the result would look something like this.
tblWineSources WineID Name SourceID Source Price Status ------------------------------------------------------------- 1 Le Dome 1 Smith 110.00 IB 1 Le Dome 3 Hill 100.00 DP 2 Teyssier 5 Hill 125.00 DP
I have table1 with orderID and demographic info. Table2 with orderID and items. I would like to have a results display like this: OrderIDDemographicInfo Item1Item2Item3....ect One line per order. When I do a join I displaying all items in different rows.
select updatedb.callref, updatedb.updatetxt, updatedb.udsource, opencall.suppgroup from updatedb left join opencall on updatedb.callref=opencall.callref
where udindex = '0' and suppgroup = 'SUPPORT' and (updatetxt like '%' + @Word + '%')
And opencall.status <> '17'This means that when they search for items and they separate each word it is "and" between each one.
They would like it to be more fuzzy with "and" and "or". How can I adapt this?
I have a dropdown list with checkbox and when I select multiple options and search, its returning only the last selected value in the grid. Here is the code I use it for search. Designation is the column where I bind its values to the checkbox.
Use the Northwind database Products table as an example.Purchasing dept gets a report showing when inventory items on hand qty arebelow the reorder level.easy enough:Select ProductID, ProductName, SupplierID, UnitsInStock, ReorderLevelfrom Productswhere (UnitsInStock < ReorderLevel)Results:ProductID ProductName SupplierID UnitsInStock ReorderLevel2 Chang 1 17253 Aniseed Syrup 1 1325It would be nice to know what other products are purchased from this samevendor in case other items are close to their reorder level.All products for Supplier ID 1Select ProductID, ProductName, SupplierID, UnitsInStock, ReorderLevelfrom Productswhere SupplierID = 1Results:ProductID ProductName SupplierID UnitsInStock ReorderLevel1 Chai 1 39102 Chang 1 17253 Aniseed Syrup 1 1325This shows there is 1 more product (Chai) that also comes from Supplier 1.Is there a way to show all items from a vendor when some of the items arebelow the reorder level without needing a separate query for each vendor?Thanks
I have a query that returns material(items) that are used in an event on a certain day.
SELECT C.categoryName, count(I.itemID) AS InMission from items as I RIGHT JOIN Categories AS C on I.categoryID = C.categoryID INNER JOIN LinkMissionItem as LM on I.itemID = LM.itemID INNER JOIN Missions as M on LM.missionID = M.MissionID where '2015/12/19' BETWEEN M.freightLeave and M.freightReturn AND isReturned = 0 GROUP BY C.categoryName, C.categoryID ORDER BY C.categoryID
There are a total of 20 categories and I would like all the categories listed in the result even though there are no items booked in a mission. At the moment, I can only get the categories that have items in that category booked in a mission. I hoped that the RIGHT JOIN on the categories table would do the trick but it doesn't.
I am looking to filter the query using the free text predicate Contains for one of the column that have dimensions of the items. The query is something like
Select * from sampletable where contains(filtercolumn, 'Near("*cm , *cm , *cm , *Kg.",10,True)')
Data in the filtercolumn is something like 64cm x 25cm x 35cm = 10Kg.
The query do not return any data.I also tried running the below query to see if cm* can be searcher for, but with no result again
Select * from sampletable where contains(filtercolumn,, '"cm*"')
If I do something like below, it does return all columns that have 35cm within the text. Select * from sampletable where contains(filtercolumn,, '"35cm"')
I have a query that returns the data about test cases. Â Each test case can have multiple bugs associated to it. Â I would like a query that only returns the test cases that have all their associated bugs status = closed.For instance here is a sample of my data
TestCaseID TestCaseDescription  BugID BugStatus 1         TestCase1            1    Closed 2         TestCase1            2    Open 3         TestCase2            11   Closed 4         TestCase2            12   Closed 5         TestCase2            13   Closed
How can I limit this to only return TestCase2 data since all of that test case's bugs have a status of closed.
Hi! i have a column named number(int),ref_number(char),date(date),creator(ch ar)...what would be my query string, if posible, to get the highest value for clumn 'number'? by the way im using SQL Desktop Engine... any inputs will be greatly appreciated...thanks in advanace!
Ok, I want to write a stored procedure / query that says the following: Code: If any of the items in list 'A' also appear in list 'B' --return false If none of the items in list 'A' appear in list 'B' --return true
In pseudo-SQL, I want to write a clause like this
Code:
IF (SELECT values FROM tableA) IN(SELECT values FROM tableB) Return False ELSE Return True
Unfortunately, it seems I can't do that unless my subquery before the 'IN' statement returns only one value. Needless to say, it returns a number of values.
I may have to achieve this with some kind of logical loop but I don't know how to do that.
