How To Remove Partially Duplicate Rows From Select Query's Result Set (DB Schema Provided And Query Provided).
Jan 28, 2008
Hi,
Please help me with an SQL Query that fetches all the records from the three tables but a unique record for each forum and topicid with the maximum lastpostdate. I have to bind the result to a GridView.Please provide separate solutions for SqlServer2000/2005.
I have three tables namely – Forums,Topics and Threads in SQL Server2000 (scripts for table creation and insertion of test data given at the end). Now, I have formulated a query as below :-
SELECT ALL f.forumid,t.topicid,t.name,th.author,th.lastpostdate,(select count(threadid) from threads where topicid=t.topicid) as NoOfThreads
FROM
Forums f FULL JOIN Topics t ON f.forumid=t.forumid
FULL JOIN Threads th ON t.topicid=th.topicid
GROUP BY t.topicid,f.forumid,t.name,th.author,th.lastpostdate
ORDER BY t.topicid ASC,th.lastpostdate DESC
Whose result set is as below:-
forumid
topicid
name
author
lastpostdate
NoOfThreads
5
17
General
NULL
NULL
0
On modifying the query to:-
SELECT ALL f.forumid,t.topicid,t.name,th.author,th.lastpostdate,(select count(threadid) from threads where topicid=t.topicid) as NoOfThreads
FROM
Forums f FULL JOIN Topics t ON f.forumid=t.forumid
FULL JOIN Threads th ON t.topicid=th.topicid
GROUP BY t.topicid,f.forumid,t.name,th.author,th.lastpostdate
HAVING th.lastpostdate=(select max(lastpostdate)from threads where topicid=t.topicid)
ORDER BY t.topicid ASC,th.lastpostdate DESC
I get the result set as below:-
forumid
topicid
name
author
lastpostdate
NoOfThreads
5
17
General
NULL
NULL
0 I want all the rows from the Forums,Topics and Threads table and the row with the maximum date (the last post date of the thread) as shown above.
The scripts for creating the tables and inserting test data is as follows in an already created database:-

I am currently trying to write a query that pulls a summation of item specific data from sales orders. For simplicity's sake, the column structure can be something like the following...
Item#, PoundsDuringWeekNumber (this would be the current week number out of the 52 weeks in a year and the pounds of the item during that week)
However, those are not going to be the only 2 columns. The idea of the query is that the user would be able to provide the query a date range (say 2 months) and the columns would then morph into the following...
Item#, PoundsDuringWeekNumber (current), PoundsDuringWeekNumber(current - 1), PoundsDuringWeekNumber (current - 2), etc. etc. PoundsDuringWeekNumber(current - 8)
Initial ideas where to create a function to execute the summation of the pounds during the date range of the week in question and execute it across the columns, but with the indeterminable number of columns, the query would not know how many times to execute the function.
I have 4 tables (SqlServer2000/2005). In the select query, I have FULL JOINED all the four tables A,B,C,D as I want all the data. The result is as sorted by DDATE desc:- AID BID BNAME DDATE DAUTHOR 1 1 abcxyz 2008-01-20 23:42:21.610 c@d.com 1 1 abcxyz 2008-01-20 23:41:52.970 a@b.com 1 2 xyzabc 2008-01-21 00:17:14.360 c@d.com 1 2 xyzabc 2008-01-20 23:43:17.110 a@b.com 1 2 xyzabc 2008-01-20 23:42:43.937 a@b.com 1 2 xyzabc NULL NULL 2 3 pqrlmn NULL NULL 2 4 cdefgh NULL NULL Now, I want unique rows from the above result set like :- AID BID BNAME DDATE DAUTHOR 1 1 abcxyz 2008-01-20 23:42:21.610 c@d.com 1 2 xyzabc 2008-01-21 00:17:14.360 c@d.com 2 3 pqrlmn NULL NULL 2 4 cdefgh NULL NULL I want to remove the duplicate rows and show only the unique rows but contains all the data from the first table A. I have to bind this result set to a nested GridView.
Working in Sql Server 2005,got 3 different table.Need to fetch the list of persons.A person can belong to different categories.When i am using inner join on tables i am getting the duplicate rows because a perosn can belong to different categories.I want that there should be only onoe row for the person and the different categories he belongs to can come up in single field as comma sepatated string Now the results are like this: firstname lastname adress category abc xyz aaa a abc xyz aaa b abc xyz aaa c I want like below: abc xyz aaa a,b,c I am thinking of using cursors in the stored procedure.Can you provide me the solution of this including the stored procedure..

I have following problem. I would like to provide to my STP encrypted data and decrypt them inside it. To decrypt the data I'd like to use DecryptByKey. Encryption should be made on the Win32/.NET client.
Unfortunately I cannot find the way to make the data understable between the both worlds. First how to assign the same key on the both side? Do I get the same key from
Code Snippet
create symmetric key MyKey with
algorithm=triple_des,
key_source='abrakadabra'
encryption by password='aaa'
and from
Code Snippet
string Key = "abrakadabra";
byte[] bKey = Encoding.ASCII.GetBytes(Key);
byte[] salt = new byte[8];
RNGCryptoServiceProvider rnd = new RNGCryptoServiceProvider();
rnd.GetBytes(salt);
PasswordDeriveBytes pdb = new PasswordDeriveBytes(bKey, salt);
TripleDESCryptoServiceProvider prov = new TripleDESCryptoServiceProvider();
I have read somewhere that create symmetric key calls CryptDeriveKey, but I'm not sure.
The next point is the format of the output data. I have noted, that the output from EncryptByKey is 16 bytes longer (after stripping key guid and fixed 0x01000000) than the one from Win32/.NET application. I assume, that it can lie in the inserting of IV as the first block, but should not IV be only 64 bit long in the DES family of algorithms?
Neverthless I have not magaged to perform encrypted communication such way between SQL Server 2005 and client application. Is it possible at all?
I have been working with a client on a legacy application migration to SSIS and I found SSIS to be very helpful, as this is my first project using integration services I found myself in a situation where multiple solutions can work but I cannot assess the risk of using one or the other and the effort required for the implementation.
The situation is as following, we cannot touch the input files that come from the other legacy systems so I need to get information that is packaged following the next multipart schema:
&Header with context information from the source &BatchHeader with context information from the batch (including format N) - Data in format N &BatchHeader with context information from the batch (including format K) +Data in format K &BatchHeader with context information from the batch (including format P) =Data in format P
Etc... Needless to say that they can come in whatever order and they need different processing depending on the format. I have been tempted to use the techniq shown in "Handling Different Row Types In The Same File" from http://www.sqlis.com/default.aspx?54.
However, there are multiple issues that I have to resolve to do that: First is how to feed the pipeline with the Data in format N and then reparse them in an easy way cause the data that comes from the other system is very wide (aprox 120 columns), so using a parsing script is by no means a viable solution (I have multiple formats to handle). So I do not see a way to treat the data without using a Custom Connection Manager. Here comes my first question: Is there anyway someone can use the already provided managers to handle an scenario like this one?
Next comes the separation, which one is the wisest thing to do: Write again that to disk in as easier format or pass along that information to the next task in memory? The volume of data is in the order of hundreds of megabytes (100 to 200), maybe half a Gigabyte in the extreme cases. How about uploading that to SQL Server and work from there?
BTW, the production servers will have 6 to 8 Gb of memory and 4 to 8 processors (more or less).

Hello, can anyone tell me if it is possible to conditionally join tables? If so, how could it be done?
What I would like to do is create a query similar to the one below but include the rows in the Asset table where the corresponding Alert field is NULL.
Assets AS A ON AL.IndustryId = A.IndustryId AND AL.RegionId = A.RegionId AND AL.RevenueId = A.RevenueId WHERE AlertId = 1
The output I am after would be the first row in the Assets table. But since the RevenueId column is NULL, I get nothing. The only time the above query will work is if all three Id columns are populated. That is not always going to be the case. Please don't suggest changing table structures or adding data. That is not an option.

I have a database being populated by hits to a program on a server.The problem is each client connection may require a few hits in a 1-2second time frame. This is resulting in multiple database entries -all exactly the same, except the event_id field, which isauto-numbered.I need a way to query the record w/out duplicates. That is, anyrecords exactly the same except event_id should only return one record.Is this possible??Thank you,Barry
I have two tables .. in one (containing user data, lets call it u).The important fields are:u.userName, u.userID (uniqueidentifier) and u.workgroupID (uniqueidentifier)The second table (w) has fieldsw.delegateID (uniqueidentifier), w.workgroupID (uniqueidentifier) The SP takes the delegateID and I want to gather all the people from table u where any of the workgroupID's for that delegate match in w. one delegateID may be tied to multiple workgroupID's. I know I can create a temporary table (@wgs) and do a: INSERT INTO @wgs SELECT workgroupID from w WHERE delegateID = @delegateIDthat creates a result set with all the workgroupID's .. this may be one, none or multipleI then want to get all u.userName, u.userID FROM u WHERE u.workgroupIDThis query works on an individual workgroupID (using another temp table, @users to aggregate the results was my thought, so that's included) INSERT INTO @users SELECT u.userName,u.userID FROM tableU u LEFT JOIN tableW w ON w.workgroupID = u.workgroupID WHERE u.workgroupID = @workGroupIDI'm trying to avoid looping or using a CURSOR for the performance hit (had to kick the development server after one of the cursor attempts yesterday)Essentially what I'm after is: SELECT u.userName,u.userID FROM tableU u LEFT JOIN tableW w ON w.workgroupID = u.workgroupID WHERE u.workgroupID = (SELECT workgroupID from w WHERE delegateID = @delegateID) ... but that syntax does not work and I haven't found another work around yet.TIA!
I have a column colC in a table myTable that has a value (e.g. '0X'). The position of a non-zero character in column colC refers to the ordinal position of another column in the table myTable (in the aforementioned example, colB).
To get a column name (i.e., colA or colB) from table myTable, I can join ("ON cte.pos = cn.ORDINAL_POSITION") to INFORMATION_SCHEMA.COLUMNS for that table catalog, schema and name. But I want to show the value of what is in that column (e.g., 'ABC'), not just the name. Hoping for:
COLUMN_NAME Value ----------- ----- colB Â Â Â Â 123 colA Â Â Â Â XYZ
I've tried dynamic SQL to no success, probably not executing the concept correctly...
I receive this error when I make a depolyment to our new server(virtual server). The report works fine in the report manager. In my application, I use RenderStream method to retrieve the images and embed in the webform. I googled it and found some people having the same issue because of the cookie, so they set 'UseSessionCookies' = false in the table ConfiurationInfo of ReportServer database. I tried this, but no luck.
Also, there is a hotfix from Microsoft http://support.microsoft.com/kb/913363. I have requested a copy, but not sure whehter it's gonna be helpful.

SELECT * FROM Map INNER JOIN ThreatCategory INNER JOIN Threat ON ThreatCategory.threatCategoryID = Threat.threatCategoryID INNER JOIN Threat_Map ON Threat.threatID = Threat_Map.threatID ON Map.mapID = Threat_Map.mapID LEFT JOIN person on map.contentPersonID = person.personID WHERE (((DATEDIFF(dd, Map.dataAcquisitionDate, GETDATE()) > map.goodForDays) and (map.expired = '1')) or (map.expired = '3'))
The problem is the table Threat_Map is a many to many mapping between the Map table and the Threat table. Eg) A map can have more than one threat and a threat can have more than one map. I know this is not the best way to have a database set up but its out of my hands as to changing the database. What I need help with is this.
My application checks as to whether a certain field in the Map table is expired or out of date (as in the query). If so it gets some required information from the other tables using those joins. However, I don't want to get information for the same Map.mapID that's expired twice. I don't really care which ThreatID I get from the Threat_Map table I just need to get one of them to meet the objects standards. However, so far this seemingly simple task has eluded me. I'd like to do this in SQL. Is there perhaps a way to do this. If not I guess I'll just take care of it in the application.
Hi everyone.How can I get the unique row from a table which contains multiple rowsthat have exactly the same values.example:create table test (c1 as smallint,c2 as smallint,c3 as smallint )insert into test values (1,2,3)insert into test values (1,2,3)i want to remove whichever of the rows but I want to retain a singlerow.TIADiego
I've got the following table data:116525.99116520.14129965.03129960.12129967.00And I need to write a query to return only rows 2 and 4, since theremaining rows have duplicate IDs. I've tried the Group By, but amhaving no luck.Thanks!
I'm trying to write a query that will return rows within a specified range and print to a Crystal Report. When I run the query, it produces 2 row of everything. I would use the SELECT DISTINCT clause, but Crystal Reports will not let me edit the Select statement. But I can edit the FROM, WHERE and ORDER BY clauses. I think the problem is in my INNER JOINS but I'm having a problem figuring it out. Can someone please guide me in the right direction.
SELECT DrawingVouchers."PlayerID", DrawingVoucherNumbers."PromoID", DrawingVoucherNumbers."VoucherNumber", DrawingVoucherNumbers."IssueDate", DrawingVoucherNumbers."UserID", CDS_PLAYER."LastName", CDS_PLAYER."FirstName", CDS_ACCOUNT."Address1A", CDS_ACCOUNT."City1", CDS_ACCOUNT."State1", CDS_ACCOUNT."Zip1" FROM { oj (("WinOasis"."dbo"."DrawingVouchers" DrawingVouchers INNER JOIN "WinOasis"."dbo"."DrawingVoucherNumbers" DrawingVoucherNumbers ON DrawingVouchers."PlayerID" = DrawingVoucherNumbers."PlayerID") INNER JOIN "WinOasis"."dbo"."CDS_PLAYER" CDS_PLAYER ON DrawingVoucherNumbers."PlayerID" = CDS_PLAYER."Player_ID") INNER JOIN "WinOasis"."dbo"."CDS_ACCOUNT" CDS_ACCOUNT ON CDS_PLAYER."Player_ID" = CDS_ACCOUNT."Primary_ID"} WHERE DrawingVoucherNumbers."VoucherNumber" >= 37806 AND DrawingVoucherNumbers."VoucherNumber" <= 37813
I have a table with one column, and i want to remove those records from the table which are duplicate i meant if i have a records rakesh in table two time then one records should be remove... my tables is like that
My site have a complicated search, the search give the results in two stages- the first one giving the number of results in each section:
"In the forums there is X results for the word X In the articles there is X results...."
And when the user click one of those lines, the list shows the specific results in that section.
My problem is that I don't know how to calculate the first part, for now I use dataset, and table.rows.count to show the number of results in each section. Since my site have more then ten, it looks like a great waste to fill such large dataset (in some words it can be thousands of rows in each section) only for getting the number of rows…
Are there is a sql procedure or key word that will give me only the number of results (the number of times that specific word showing in the columns?)
We are getting error and we are aware that there should be 2 files but we are able to find the second file,how to search all files(2) so that we may restore DB.
I have three tables, Accounts, AccountCustomer and Customers, and the data-relationshiop between are defined according to the image below:
I created also a query (the sql-query below), displaying the customers for every account that is on the table "Accounts", and I got the results, as we can see in the image below:
SELECT A.AccountID, c.CustomerNo, c.Surname, c.Name, c.TaxNum FROM Accounts A left join AccountCustomer ac on ac.AccountID = A.AccountID left join Customers c on c.CustomerNo = ac.CustomerNo order by A.AccountID;
As we understand, an "AccountID" have multiple customers, so I want to transform tha multiple results to one row, grouping by AccountID (one account belongs to one or many Customers), like the image below:
I tried to use row_number()-expression to get this, but I didn't make it. So my question is, how can I alter my sql-query to get the final result like image above?
I need to remove "rows affected" text from results as shown below from posted Sp. I am using set nocount on but its not working as expected.
Create Procedure DailyCheckList As SET NOCOUNT ON Declare @EmailSub varchar(500),@dt varchar(100),@Msg varchar(max),@M varchar(max) set @dt= convert(varchar(20),GETDATE(),107)
When I run simple select against my view in Query Analyzer, I get result set in one sort order. The sort order differs, when I BCP the same view. Using third technique i.e. Select Into, I have observed the sort order is again different in the resulting table. My question is what is the difference in mechanisim of query analyzer, bcp, and select into. Thanks
We have a query that uses the Full-text index on a view that's returning duplicate rows. We thought maybe it was the way we were joining, but we were able to simplify the query as much as possible and it still happens. Here's the query:
Code Snippet SELECT * FROM FREETEXTTABLE(vwSubtable, TitleSearch, 'Across five Aprils') AS KEY_TBL ORDER BY RANK DESC
vwSubtable is an indexed view that contains some of the columns in our original table, and is also filtering out some rows from the main table in a where clause. There are no joins in the view.
This seems like it's about as simple a query as we could get. It will return some rows twice (ie. the same primary key row is returned back as two separate rows in the resultset). This is a problem since we're filling a datagrid, which is throwing a ConcurrencyException because the primary key is already in there.
I made sure we have SP2 installed on my SQL Server. Any ideas on what might be happening?
