I have a table with call data (ContactID, Queues Entered, Call Status, Date & Time Stamps etc). Each entry relating to a contact ID goes onto a new row. The first row for a contact is the date and time it is created. It then captures the queue (or queues) it enters before it is answered. Finally, it captures when the call is released (Completed).
I'm trying to link all this data into one single row per contact ID to make it easier to report on.
I started off by using DISTINCT to pull back all of the Contact ID's. I then used a Left Join to pull back the date and time of creation. I created a further Left Join to pull back the first queue that it entered and so on.
When I did this, I started getting duplicates. This is because some calls enter more than one queue.
How can I do this so that it only has one ContactID per row. Also, for the Queue, is there anything I can do to ensure it pulls back the first Queue it enters? (These are time stamped). Subsequently, I would then need to add the second and third queue it enters in other columns. (A call can enter a maximum of 3 queues).
I was wondering if someone could help me with the results on this query, at the moment I am getting values repeated and I was wondering if it was possible to have some of the columns grouped, I have tried to have grouping at the end of the query but this still did not group the rows.
Thanks in advance for your answer - Sean

I am trying to move data from one table to the another (staging to real time) in a stored procedure.
There are no indexes or primary keys on the target table and it is still taking ages to execute it (30 minutes approx.). There are no defaults, no constraints as well. There is one identity int column though.
There are some 500000 odd rows in the target table.
I'm running SQL server 2000 sp1. I created a stored procedure that (1) drops a table, (2) recreates it with a "select into" statement, (3) alters the table by adding a field, and then (4) updates that field.
The trouble I'm having is that when I execute the stored procedure I get an error stating that I have an "invalid column name" between steps (2) and (3). It seems as though when I drop the table in step (1), the entire procedure wants to re-compile and it can't get past step (4) because the table hasn't been altered yet.
I've noticed a similar problem in editing stored procedures when they refer to tables or fields that don't exist yet because WITHIN the procedure they are created/modified. I'm not able to get a successful syntax check and therefore not able to save my work.
I have a sql snippet from a 3rd party application that will not complete its transaction. The SELECT statement executes but does not finish. Instead the statement just sits in AWAITING COMMAND for 1000 seconds then dies, thus killing the UPDATE statement that is supposed to follow.
I am wondering if tempdb stores all results tempararily whenever I query a large fact table with over 4 million records which joins another dimension table? Since each time when I run the query, the tempdb grows to nearly 1GB which nearly runs out all the space on my local system drive, as a result the performance totally down. Is there any way to fix this problem? Thanks a lot in advance and I am looking forward to hearing from you shortly for your kind advices.
I have a table with 22 million Business records. I can see that there are duplicates when I group by BusinessName and Address and Phone. I'd like to place only the duplicates into a table, with a ranking, oldest business key gets a ranking of 1.
As a bonus I'd like each group to have a distinct group name (although not necessary, just want to know how to do this)
Later after I run more verifications to make sure these are not referenced elsewhere I'll delete everything with a matchRank > 1 out of the main Business table.
DROP TABLE [dbo].[TestBusiness]; GO CREATE TABLE [dbo].[TestBusiness]( [Business_pk] INT IDENTITY(1,1) NOT NULL, [BusinessName] VARCHAR (200) NOT NULL, [Address] VARCHAR(MAX) NOT NULL,
Hi, I have table which stores the fund name and its data. We get quarterly information from the fund co. Suppose if the user wants to add a fund thats not in our database we let then add a ClientFundId and a FundName. But may be after sometime the fund company may add that fund in the next quarter.. So how do i get rid of Duplicated Data.. In the ClientFundId column we can a 9 letter Aplhanumeric or a 5 letter character but if the fund co.. provides those values the 5 letter characters are stored in Ticker column and the 9 letter words are stored in Cusip column.. So i just wrote this query hoping i could retrieve the duplicate values but it didnt list any..but i found one this is my query.. Select FundId, Cusip, Ticker, ClientFundId, FundName, ShortName From Fund Where
ClientFundId = Ticker or ClientFundId = Cusip Any help will appreciated Thanks Karen
does someone have a querry to display the duplicate records in a table.
Table: zipcode dma
My data upload is failing because there is a primary key on zipcode and the source data (42k records) has about 50 duplicate zipcode records in it. It is possible that there is a unique combo of zipcode / dma but I need to identify the duplicate records to determine that.
I have this script bellow which does what it is supposed to. However it only outputs the cust_id. I want it to show all the columns in the table. How would I do this?
SELECT cust_id FROM cust_table WHERE cust_name in ('Billy','John') and rownum < 100 GROUP BY cust_id HAVING COUNT(*) > 1;
The database has Name,Email, and skill. Though the name is distinct it is repeated as it has different skills. I would like to remove duplicate names and add the corresponding skill to the only one row.
From the stored procedure, combining 3 tables I got the output as:
NameemaildepartmentSkill ArunemailidTech teamTechnical ArunemailidTech teamLeadership ArunemailidTech teamDecision Making BinayemailidMarketingTechnical BinayemailidMarketingDecision Making
I would like to remove the duplicate Name fields and combine the Skill in a single row as other fields are same.
So the output should be
NameemaildepartmentSkill ArunemailidTech teamTechnical, Leadership, Decision Making BinayemailidMarketingTechnical,Decision Making
how i can check for duplicate entries for example if a serial number has already been inputted and a user tries to input the same serial number.. how can i get a trigger or some sort to check for duplicates and then prompt that the number has already been entered.
Im trying to look for duplicates in a table field.. field name is alphanumericCol and table is a user defined table...This is my trigger:
ALTER TRIGGER [dbo].[DUPLICATES] ON [dbo].[AMGR_User_Fields_Tbl]
FOR INSERT, UPDATE AS DECLARE @Alphanumericcol VARCHAR (750)
-- This trigger has been created to check that duplicate rows are not inserted into table.
-- Check if row exists SELECT @Alphanumericcol FROM Inserted i, AMGR_User_Fields_Tbl t WHERE t.AlphaNumericCol = i.AlphaNumericCol AND t.Client_Id = i.Client_Id -- (@Alphanumericcol = 1) -- Display Error and then Rollback transaction BEGIN RAISERROR ('This row already exists in the table', 16, 1) ROLLBACK TRANSACTION END
The result i get is, if i input a duplicate number it fills in a null in the field so my question is how do i get it to tell me its duplicate and let me insert a new one

There is a table with a single column with 75 rows - 50 unique / 25duplicates. How would pull back a list of the rows that have/areduplicates?This is a question that I got in an interview. I didn't get it,obviously....Thanks,Tim
I have a very large table that can contain up 3 to 5 duplicate records. Every month around 100,000 new records come in. Sometimes it's an ammended record, other times is just duplicated by error.
Is it possible to keep the latest record dumped into the table and delete the others? Does SQL track the order of the data being dropped into the table?
The layout would look like this. There are 10-15 other columns in the table where adjustments can also be made.

How do I only select rows with duplicate dates for each person (id)? (The actual table has approximately 13000 rows with approximately 3000 unique ids)
Hiya everyone,I have two tables in SQL 2000. I would like to append the contents ofTableA to TableB.Table A has around 1.1 Million Records.Table B has around 1 Million Reocords.Basically TableA has all of the data held in TableB plus 100,000additional records. I would only like to import or append these newadditional records. I have a unique index already setup on Table B.Any ideas pretty pretty please?Paul.Ps. (Have been messing around with DTS but get a unique violation error- Which is kinda what I want I guess, but would like SQL to ignore theerror and only copy the new data - if only)
(i am not sure which forum to post this too) Hi, I imported a table onto my host's server, table_Login which has username password, and userID. userID is Primary Key & identity. When I had my code do insert of new user, I was getting error the Login.userID doesn't allow null values. Which shouldn't have mattered because userID is an identity. After making a diagram from Enterprise Manager, I noticed that I have two Login tables (although only one shows in Enterprise Manager's "Table" node view. The second table, which had none of the constraints that my table of the same name which is listed under the "Table" node does; appears to be the table which is being written to by my code. I can't find this table, Login(dbo), through Enterprise Manager, nor am i sure how to access it through Query Analyzer. Needless to say, I don't like this arrangement. and well tech support for this host seems to leave a lot to be desired. Anyone know what needs to be done so that I can fix it or fight with tech support to convince them that they should?
HiOur product uses MS-SQL Server 2000. One of our customer has 10installations with each installation stroring data in its own database.Now the customer wants to consolidate these databases into one and wealready have plan for that by consolidating one DB at a time. But firstthey want to find how many unique or duplicate entries they have acrossall the 10 databasesAssumptions:1. All the databases reside on the same server. (This is just anassumption, not the real environment at customer site)2. Databases can not be merged before it is found how many unique orduplicate rows exist.Table under consideration:Message(HashID PK,....)# of rows in Message table in each of databases: 1 MillionHere is my question: How can I find how many unique or duplicateentries they have across all the 10 databases. I easily find uniquerows for two databases with a query like this:SELECT COUNT(A.HasID) FROM db1.dbo.Message A LEFT OUTER JOIN ONdb2.dbo.Message B ON A.HashID = B.HashID WHERE B.HashID IS NULLHow can I do this for 10 databases. This will require factorial of 10queries to solve this problem.I will appreciate if someone can provide hint on this.RegardsAK
I have table with columns as ID, DupeID1, DupeID2. ID column is unique. DupeID1 and DupeID2 -- the combination should only be there once. I don't want reverse combination of duplicates, i.e. DupeID2, DupeID1 in the table. How can I delete the reverse duplicates from this table?
Just curious if anyone has any in depth knowledge of how table join filtering works:
SELECT col1 FROM tbl1 a INNER JOIN tbl2 b ON a.col2 = b.col2 AND a.col3 = 1
(versus)
SELECT col1 FROM tbl1 a INNER JOIN tbl2 b ON a.col2 = b.col2 WHERE a.col3 = 1
Running some simple tests, the executions plans look identical. Does anyone know if/when either of these options would be preferential over the other? This is a rather difficult topic to Google and find any decent information.
I was looking at some sample queries on how to do product promotion. Basically im after the top few products that have been ordered along with a given product ID. I think this should do it, but wasnt sure about the 2nd join...and why ?
SELECT ProductID, ProductName, SUBSTRING(Description, 1, 150) + '...' AS Description FROM Products WHERE ProductID IN ( SELECT TOP 5 details2.ProductID FROM OrderDetails details1 INNER JOIN OrderDetails details2 ON details1.OrderID = details2.OrderID WHERE details1.ProductID = @ProductID AND details2.ProductID != @ProductID GROUP BY details2.ProductID )

Please help in how to write such SQL? Thanks in advance
I'm having two general problems trying to do a JOIN. I have a table withthree fields {Code, Date, Amount}. Code+Date is a unique key. I'm tryingto get a rowset with 1) one row for each unique Code+Date pair, 2) andwith each row containing, {Code, Amount for Date-A and Amount forDate-B}. Basically, I want to create two temp tables with the Amounts fora specified Date and then Join them.The problems are1) I'm trying to do this in SQL-Server 7 with a single stantment, and2) If a Code+Date pair doesn't have any Amounts, I'd still like a rowreturned with NULLs.Anybody have any wisdom on this??Thanks
I got this problem where I need to look up values in two columns fromanother table.I can get OUTER LEFT JOIN working when looking up one column from a tablebut when looking up at two columns from a table I can't get the SQL syntaxcorrect.The scenario isA table has definitions for abbreviation of initials. From my search querythere are two columns of initials, I am having problems in writing an SQLstatement to look up and replace both columns of initials with theircorrect definitions. I was using an OUTER LEFT JOIN statementI am sorry if this isnt the correct Newsgroup to post this.
