I im trying to write a SELECT query to display a set of my logged in user's 'Friends'. Although the way that i have designed my tables means that its very complex, and im hoping someone out there can tackle it!
To start ill show you how i contruct friends:
Friends
FriendshipID Incrementing PK
InviteeID Unique UserID of person who offered the friendship link
InvitedID Unique UserID of person who was invites
ApprovedBInvitee True/False - sets to 'True' by default (probably isnt needed come to think of it )
ApprovedByInvited True/False/Declined - an nvarchar
Next, I have my UserDetails table:
UserDetails
UserID Unique UserID PK
UserName Unique Username (foreign key from aspnet_Users as created by aspnet_regsql.exe)
Avatar Integer which represents an image name in a photos folder
So, on the myFriends.aspx i firstly set an invisible label's text property to the unique UserID of the logged in user. This gives me a control paremater for the select statement.
The information I want to display is just the UserName and Avatar of all users who are friends with the logged in user.
I know that to get the records where the logged in user is either that Invited or the Invitee, I do this:WHERE (@loggedInUser = Friends.IniteeID) OR (@loggedInUser = Friends.InvitedID)
(that will show the logged in user as his own friend but i dont mind that)
After that I am stuck more or less... it seems to become very complex... maybe i need 2 queries?
Hi. I have two tables. The first is a price proposal table which contains fields like the index of the proposal, proposal decription, proposal date etc. The second table contains data about the products associated with a certain price proposal. This table has a proposal index field and other fields like the index of the product (a unique identifier), product catalog number, price of the product etc. I want the rows which returned by my select query to display the following: The Proposal index, description, date, product catalog number grouping, the number of products with a certain catalog number in this proposal, the sum of the prices of these products. Example: PriceProposalTable : ProposalIndex = 1 -----> ProductsTable: ProposalIndex = 1, ProductIndex = 1, CatalogNumber=A, Price=100 ProposalIndex = 1, ProductIndex = 2, CatalogNumber=A, Price=90 ProposalIndex = 1, ProductIndex = 3, CatalogNumber=B, Price=80
Ok, I have a table with two columns in the group by clause, ServerID and Database ID. I have 9 unique ServierIDs and 117 unique DatabaseIDs. I need a query that says gimme the 5 highest database id hitcount totals for each server id. I would like to do this without a #temp table or a cursor. here's what I have:
------------------------------------------------------------------- create table #server_hitcount_summary( SID int not null, DBID int not null, ORD int not null, SUM_HITCOUNT bigint not null, SUM_MAXWRITES bigint not null, SUM_MAXREADS bigint not null, SUM_MAX_DURATION bigint not null, SUM_MAX_CPU bigint not null )
declare @id int set @id = 1 while (@id < 20) begin insert #server_hitcount_summary select top (@top) SID, DBID, ROW_NUMBER() over (order by sum(hitcount) desc) as ORD, sum(hitcount) as SUM_HITCOUNT, sum(MAX_WRITES) as SUM_MAXWRITES, sum(MAX_READS) as SUM_MAXREADS, sum(MAX_DURATION) as SUM_MAX_DURATION, max(max_cpu) as MAX_MAX_CPU from hitcounts_table group by SID, DBID having SID = @id and DBID <> 1 order by sum_HITCOUNT desc set @id = @id + 1 end select SID, DBID, ORD, SUM_HITCOUNT, SUM_MAXWRITES, SUM_MAXREADS , SUM_MAX_DURATION, SUM_MAX_CPU from #server_hitcount_summary order by SID asc drop table #server_hitcount_summary -------------------------------------------------------------------
What d'ya think? is there a better way to do this?
-The Universe is naturally cold. It takes the power of a star to change that.
I have a very confusing/complicated query that I am trying to run and getting not the results that i want.
Essentially I have three tables (t1, t2, t3) and I want to select data from two of them, but there are conditions on the data where I need fields to match across pairs of tables. When I run my select query I am getting far too many records - it's giving me all possible combinations, instead of the proper combinations that I want.
Select t1.*, t3.field2, t3.field3 FROM, t1, t2, t3WHERE t2.field4=t3.field4 AND t1.field5=x AND t1.field6=t2.field6
I suspect there is plenty wrong with this query - where should I start correcting it?
Can someone help me with an advanced query?I have two tablesTable 1: EmployeesCols: UID, lname, fnameTable 2: StatEntryCols: UID, Timestamp, descriptionThe queary should reaturn all the information in both tables. If morethan one entry exists in the second table, it should return the onewith the greatest timestamp. If not entries exist I would like thesecond table columns set to "no value"Something link:select Employees.*,StatEntry.* from Employees JOIN StatEntry ONemployees.uid == statentry.uid WHERE timestamp in (selectMAX(timestamp) from statentry where uid=employees.uid).Anyone db guru's out there?-SJ
Hi,I have problem about writing a proper SELECT query for the followinggoal:Table name: peoplelistcolumn 1: id (not NULL, auto_incremental)column 2: namecolumn 3: countrynow, there are about 7,000 rows in this table. I want to select out:first 10 or less people in the table for each country.for example: suppose there are :1000 people from US3000 people from UK3000 people from CanadaI want to list totally 30 people, i.e. 10 people from each country.The problem is , the actual table includes many countries, not onlythree. How can I do this by a SELECT sql query ?Thanks.Han
Hi All, My sql is a little rusty, i ve been trying to do few things but still no luck. I m trying to query some data in one column based on certain . Here is my puzzle: I have 7 tables: categories, characteristics, configs, rm_cat, rm_chars, rm_conf and rooms. And here are the details on these tables: - categories: {cat_id, cat_name} - characteristics: {char_id, char} - configs: {conf_id, conf} - rm_cat: {room_id, cat_id} - rm_chars: { room_id, char_id} - rm_conf: {room_id, conf_id} - room: {room_id. room_name}
I m trying to select a "room_name" based on a certain cat_id, char_id and conf_id and i don't know how to do this.
There are 3 tables, VendorLists, Vendors, and Referrals.
VendorLists is a linking table. It has VendorListID, VendorID, and ListID fields.
Vendors is linked to VendorLists through the VendorID field (one to many)
Referrals is linked to VendorLists through VendorListID (one to many)
I'm given a value for ListID and have to pull records from both the Vendors and Referrals table (a referral is a description of a vendor, one to many).
I am able to do this with the following SQL select statement:
SELECT Referrals.Description, Vendors.Company FROM Referrals CROSS JOIN Vendors WHERE Referrals.VendorListID IN (SELECT VendorListID FROM VendorLists WHERE (ListID = lid)) AND (Vendors.VendorID IN (SELECT VendorID FROM VendorLists WHERE ListID = lid)) ORDER BY Vendors.VendorID
This pulls all the appropriate records and values that i need and orders them by the identifier for the vendor. However, I want to randomly order the vendors but still group them together by company, so, if the VendorID is 1 for "joe's crab shack" and 2 for "billy's ice cream shop", the above will always list joe's crab shack first and all it's referrals. i want to be able to randomly order the vendors, but still keep the referrals of those vendors grouped together so that when i iterate over them, they're grouped.
Does anyone have any idea how to do this? I'm stumped!!

I have a pretty complex SQL statement that looks like this: SELECT aspnet_Employers.active, aspnet_Employers.accountexecutiveusername, aspnet_Employers.created, aspnet_Employers.Title AS Contact, SUM(aspnet_Employers.EmployeeCount) AS [# Emps], COUNT(aspnet_Signups.account) AS [# Email Addresses], COUNT(aspnet_ContactMe.username) AS [# Contact Me], COUNT(aspnet_AppsSubmitted.account) AS [# Apply Now]FROM aspnet_Employers LEFT OUTER JOIN aspnet_AppsSubmitted ON aspnet_Employers.UserName = aspnet_AppsSubmitted.account LEFT OUTER JOIN aspnet_ContactMe ON aspnet_Employers.UserName = aspnet_ContactMe.username LEFT OUTER JOIN aspnet_Signups ON aspnet_Employers.UserName = aspnet_Signups.accountGROUP BY aspnet_Employers.accountexecutiveusername, aspnet_Employers.created, aspnet_Employers.Title, aspnet_Employers.active It does work the way i want it, but the problem is, on my Gridview when i change the Employers accounts "Active" status either way, it changes the username field from the username of the account, to "null". Why does it do this? What would i change to prevent this from happening?
I may not be seeing the forest through the trees here but here goes. I've got a table of computer configurations with columns for cpu, ram, m/b, hdd, etc. The values in those columns are related to the id field in another table named parts. The parts table has columns, id, partnumber, description, and cost. What I want to do is be able to pull a record from the computer configurations table and instead of getting the integers in the cpu, ram, etc. fields I want to put the corresponding description field from the parts table. For example:I want this...id Name CPU RAM MB HDD ... 1 Fast Machine Fast CPU Big RAM Greate MB Huge HDDNOT this....id Name CPU RAM MB HDD ... 1 Fast Machine 1 3 2 7 Below is a screenshot of my actual table relationships.Thanks in advance
hi! i have two tables: Pictures (PictureID, UserName, UserID, DateAdded, Comments int) and UserVisits (VisitID, UserName, UserID, PictureID, NewComment bit) if a new comment is added on a picture with PictureID = 4, i update NewComment from UserVisits with 1 (true) where PictureID = 4 to all rows, and if a user visits a picture with PictureID = 5, NewComment will be set to 0 back where pictureID = 5 (something like asp.net, when a reply is added to a therad) i need to make a stored procedure with UserName input parameter witch selects ALL pictures from Pictures table and selects NewComment (true or false) from UserVisits witch corresponds with that UserName !!! Is possible that in UserVisits to not have yet any column where UserName corresponds with the user who visits if the user did not visited that picture yet (this stored procedure will be used on a Repeater witch lists all the pictures) if i was not clear please tell me, sorry i am verry bad at T-SQL language thanks in advance
This is difficult to explain in words, but the following code outlines what I am trying to do:
with myTableWithRowNum as ( select 'row' = row_number() over (order by insertdate desc), myValue from ( select table1Id As myValue from myTable1 union select table2Id As myValue from myTable2 ) )
select * from myTableWithRowNum Can anyone think of a work around so that I can use the Row_Number function where the data is coming from a union?
I'm sure there is a way of cracking this, but I can't think of a good solution. Right now I am not happy with the solutions I come up with, one of which takes 4 minutes to run on SQL Server The scenario: User is presented with search page where one or more search terms can be entered/selected. There are no required parameters. It can be any or all of the possibilities presented. Below is a model of the search parameters presented. The user will either select to show more options under Profile ABC, or go down to Profile STU or Profile XYZ to show more options, or even select all Profiles and then select from Type 1 and either a. or. b. or. c. or ALL of the above. I cannot predict what a user will make part of the search query so I have to have a stored procedure ready which can handle any or all of the parameters a user may select. Am I biting off more than I can chew (it seems so)? Or is there an elegant way of handling the unknown combination of search parameters that a user might throw into my sql query? I'm running this under ASP 1.0 and SQL Server 2000.
[check to show the options below] Profile ABC [check to shore more options] Type 1
A. Contains fields for entering another data string and selecting from drop-down boxes B. ditto C. ditto D. ditto [check to show more options] Type 2
A. Contains fields for entering another data string and selecting from drop-down boxes B. ditto C. ditto D. ditto [check to show more options] Type 3
A. Contains fields for entering another data string and selecting from drop-down boxes
B. ditto C. ditto D. ditto [check to select more options] Type 4

HI. I have 3 tables 1- std with : stdID , programID. 2- Programs with :ProgramID , Cost 3 - Movements with : stdID , balance. the first table contain the stdID and ProgramID , some times the std hasn't programID that mean he hasn't programID. then we return null. if the std has programID there is to cases. the first one he have a movement on his balance then we get the biggest balance for the std. the second case he hasn't any moventen then we get his balance from Programs table by the ProgramID .
I need sql server function that return table like this stdID , Balance that means every std with his Balance. Regards.

I have 2 tables, say table1, and table2. There is a DocID (primary key) in table1. In table2, DocID is the foriegn key. There can be more than 1 DocID.
how do I join these two tables, such that I get all the otherID's for each DocID. ie., DocID OtherID 1 2 and 10 and 13 and 25 2 3
i am writing this query to display search results on a search page (with keyword search) and so, if I display the result in more than one row, then the user might think that there is more than document...whereas the case is that there is only one document with more than one other ID's.
is there any way I can do this? display...more than 1otherID in the same row for the same DociD? Currently, I am using a left outer join of table1 and table2.

I might have to redesign the tables for this, but I'll ask anyway. I have a table with the following fields:
Email - VarChar Seminar - Int PeckingOrder - Int.
As I add addresses to the table, each one has a Seminar, and then each Seminar has a Pecking Order Value. If an email address shows up for more than one seminar, it can have multiple records. IE:
for address, seminar, and pecking order would be sample entries into the table. Give or Take 1000 records in the table at any given time. What I want to pull out is:
Distinct Email Addresses For each Email Address - The Max(PeckingOrder) And the Seminar that's associated with Max(PeckingOrder)
For the sample data set above, I'd want to see these two records returned by the query:
email1 - 1523 - 424 email2 - 1524 - 235
I can't seem to get the Having / Where clause right to pull those two records properly. Anyone have any suggestions?
Thanks, --Daniel
Edited - Didn't realize the BB removed email addresses.
SELECT goto_last_name as 'Manager', advisor_name, advisor_ao_number as 'AO', COUNT (CASE advisor_termination_date WHEN '<Null>' THEN 1 END) as '#Advisors', SUM(Weekly_TOS_GDC) as 'TOS GDC' FROM weekly_condensed_tb WHERE advisor_platform_number = 1 AND report_date BETWEEN CAST(CONVERT(VARCHAR,'9/11/2007',112) AS DATETIME) -28 AND CAST(CONVERT(VARCHAR,'9/11/2007',112) AS DATETIME) GROUP BY goto_last_name,advisor_ao_number,advisor_name HAVING COUNT (CASE advisor_termination_date WHEN '<Null>' THEN 1 END) > 1
In the query above i select a range from the date - 28 days and do a sum on the TOS GDC column. What i am trying to do is have another query where the range will be - 56 and maybe - 86 so i get the SUMS for that as well. I need to display this in SQL Reporting Services and i can only have one DataSet returned otherwise i will not be able to bind it to one table.
How can i go about this so i return one set of data for 3 different date ranges.
I'm struggling with a syntax error in my sp. I'm hoping someone can give it a fresh look and straighten me out. Thanks. Background: 1. The innermost query (using the dynamic statements) will run fine on its own. 2. I can wrap that in another query (with the innermost as a DERIVEDTBL) and it will run fine UNLESS I apply the GROUP BY. Then I get syntax errors. 3. Also, the entire query runs fine as a view (with hard coded vals for column and value). 4. I don't know what kind of formatting this message will apply, so just know that I've checked my line truncations and they all include a trailing '+. Also, I know that Occured is misspelled. That is the correct object name. Not all our DB admins are lit majors.
I have a sql table with corpcode, EmpName, rate, reportdate and Amount fields. I need to write a query that can return corpcode, EmpName, rate and sum of Amount for January, Sum of Amount for Feburary, Sum of Amount for March, Sum of Amount for April, ..........., Sum of Amount for December, Total for All months, Average for all months.
I tried few option, it didn't work for me, Is it possible to do? Have some tried like this earlier?
Hi, I want to create a query with which I must compare the production demands with the production results. The production demands can be get by the join of two tables. The production results can be get from an aggregate of 4 tables. The connection of these two objects rely on two fields that exist in both two objects. In order to show all the production demands I must left join the two fields from the demands object to the two fields exist in the aggegate production object. In MsAccess the only way to do it is to create 2 queries one for the demands and one aggregate for the production and in a third query create two left joins from the demands query to the production query and get the right results. How can I do it with MSSQL Server with a query??
BLOG --POSTER_ID --POSTED_BY (a FK refer to USERID) --UPDATED_BY (a FK refer to USERID)
USER --USER_ID --NAME
I want to retrieve the info for all posts that posted and updated by different users, also the query returns both user names for every posted and updated action.
I can write two queries to do that
select B.POSTER_ID, U.NAME from Blog B inner join USER U ON B.POSTED_BY = U.USER_ID
select B.POSTER_ID, U.NAME from Blog B inner join USER U ON B.UPDATED_BY = U.USER_ID
Then write some code to combine the result for the posted and updated user name. But this is not efficient.
I am wondering how can I write one query to archeive that?
