Duplicates Again! UNION Join - Remove Records With Column Diff.
Sep 9, 2004
Hello All,
We all were new at one point.... any help is appreciated.
Objective:
Combining two 49,000 row tables and remove records where there is only 1 column difference. (keeping the specified column value removing the one with a blank.)
Reason:
I have 2 people going through a list, coding a specific column with a single letter value. They both have different progress on each sheet. Hence I am trying to UNION them and have a result of their combined efforts without duplicates.
My progress/where I'm stuck:
Here is my first query/union:
SELECT * FROM [Eds table]
UNION SELECT * FROM [Vickis table];
As shown above, I have unioned these 2 tables and my results removed th obvious whole record duplicates, but since 1 column is different on these, a union without criteria considers them unique.....
an example of duplicates that I must remove are as follows:
I have some duplicate values for my query results, about 200 duplicates out of 30000 rows. Of these 200 duplicates I want to keep the ones that have a higher value for... 'UpdatedBatchID'.
SELECT IR.Id as 'ID' , CAST(IR.Priority as varchar) as 'Priority' , IRSupportGroupDN.DisplayName as 'Support Group' , DATEADD(MI,DATEDIFF(mi,GETUTCDATE(),GETDATE()),IR.CreatedDate) as 'Created Date' , DATEADD(MI,DATEDIFF(mi,GETUTCDATE(),GETDATE()),IR.ResolvedDate) as 'Resolved Date' , SLOConfig.DisplayName as 'SLO' , DATEADD(MI,DATEDIFF(mi,GETUTCDATE(),GETDATE()),SLOFact.TargetEndDate) as 'SLO Target' , SLOStatusDN.DisplayName as 'SLO Status' , SLOMetric.DisplayName as 'SLO Metric' , SLOFact.UpdatedBatchId as 'UpdatedBatchID'
I have a requirement where i want to delete the records based on the Date column. I have table which contain the columns like machinename ,lasthardwarescandate
I want to delete the records based on the max(Lasthardwarescandate) i.e. latest one, column where the machine name is duplicate menace it repeats. So how would i remove the duplicate machine names based on the Lasthardwarescandate column(There are multiple entries for the Lasthardwarescandate so i want to fetch the latest date column).
Note: Duplication should be removed based on “Last Hardware Scan” date.
Only latest date should be considered from multiple records for the same system. "
Hello, I am doing a UNION (not UNION ALL) of two tables and two columns. The first column is AcctCode VARCHAR(16), and the second column is Revenue FLOAT.
I am getting two rows back, using UNION, where the values in both columns are the same. Basically, it looks like this:
AcctCode Revenue AM247 300.64 AM247 300.64
There are trailing spaces after the AcctCode, and I have tried RTRIM.
The following is the query I am using:
Select RTRIM(AcctCode)AS Acctcode, SUM(ISNULL(ScFee,0)) as Revenue From cdnbwfin1.txnRptg.dbo.dailySummary where TxnDate = '4/22/2008' group by Acctcode
union
Select RTRIM(AcctCode) As AcctCode, SUM(ISNULL(ScFee,0)) as Revenue From bwdbfin1.txnrptg.dbo.tbl_dailySummary where TxnDate = '4/22/2008' group by Acctcode order by acctcode
Why would I get this duplicate if I'm using UNION?
Hi - I am a newbie to t-sql and have an issue that I am not sure is me or sql I want to merge several tables from several databases. I have created a union statement:
create view myViewas select *, ‘1’ as compId, ‘AAA’ as SiteID from ClientAAA.dbo.stats UNION (select *, ‘2’ as compID, ‘ABC’ as SiteID from clientABC.dbo.stats UNION (select *, ‘3’ as compID, ‘ABD’ as SiteID from clientABD.dbo.stats UNION (select *, ‘4’ as compID, ‘ABF’ as SiteID from clientABF.dbo.stats UNION (select *, ‘5’ as compID, ‘AGG’ as SiteID from clientAGG.dbo.stats )))) Its ok till the last statement then they repeat from the 4th line stats. Any help would be great

I have a situation where we get XML files sent daily that need uploading into SQL Server tables, but the source system producing these files sometimes generates duplicate records in the file. The tricky part is, that the record isn't entirely duplicated. What I mean, is that if I look for duplicates by grouping the key columns, having count(*) > 1, I find which ones are duplicates, but when I inspect the data on these duplicates, the other details in the remaining columns may differ. So our rule is: pick the first record, toss the rest of the duplicates.
Because we don't sort on any columns during the import, the first record kept of the duplicates is arbitrary. Again, we can't tell at this point which of the duplicated records is more correct. Someday down the road, we will do this research.
Now, I need to know the most efficient way to accomplish this in SSIS. If it makes it easier, I could just discard all the duplicates, since the number of them is so small.
If the source were a relational table, I could use a SQL statement to filter the records to remove the duplicates, but since the source is an XML file, I don't know how to filter these out in the pipeline, since the file has to be aggregated to search for dups.
This SQL is meant to show the changes that will be made, when removing a selected user's email address from a batch.
However, when executed, each row is duplicated, and in the duplication, the semi-colon or comma isn't removed. For example, if I wanted to remove user "sam@mail.com"
Ideally, it should only display each row once, and not have the semicolon error. It seems to be a union error, because when I comment out the First and second union statements, it runs fine.
-- Delete email address from a.Batch
IF(@EmailAddress IS NOT NULL) BEGIN IF(LEN(@EmailAddress) > 0) BEGIN IF(@ShowOnly = 1)
DELETE FROM tblContacts WHERE tblContacts.ID IN( SELECT F.ID FROM tblContacts AS F WHERE Exists ( SELECT email, Count(ID) FROM tblContacts WHERE tblContacts.email = F.email GROUP BY tblContacts.email HAVING Count(tblContacts.ID) > 1 ) ) AND tblContacts.ID NOT IN( SELECT Min(ID) FROM tblContacts AS F WHERE Exists ( SELECT email, Count(ID) FROM tblContacts WHERE tblContacts.email = F.email GROUP BY tblContacts.email HAVING Count(tblContacts.ID) > 1 ) GROUP BY email )
I readily admit that I've shamelessly copied 'n pasted this from a tutorial and then taken a stab at tweaking it for my own ends. But I really don't understand what it's doing.
Really, all I want to know is that it will remove records with duplicate email fields. But I could also do with confirming - looking at the "SELECT Min(ID)" bit - does that mean that if it finds a duplicate, it'll delete the latest-added one? And if so, that changing it to remove the earliest-added one is simply a case of changing MIN to MAX?
I am working with a bunch of records that have duplicates on the Persid and the intPercentID where there are duplicates I want to remove when I stick them in the temp table, I tried join on tempo table and doing not exists but still inserts, so now I am trying a merge but same thing. how can I keep duplicates from being inserted in the temp table. I made a cursor as well but its slow as heck, but it does work. trying better ways.
Create table #TempStr (STRId int not null Identity(1,1) primary key, Persid int, percentId int, dtCreated datetime, CreatedBy int)
INSERT #TempStr (Persid, percentId, dtCreated, CreatedBy) select intPersonnelID, intPercentID, dtSubmitted, intSubmittedBy from tblSTR whereintpercentId in (61,62) group by intPercentID, intPersonnelID, dtSubmitted, intSubmittedBy UNION ALL
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?
Product No Grade Quantity A Good A Normal A Bad B Good B Bad C Good C Normal C Bad
In Table 2, Product No divided by Grade. I want to lookup the Quantity from Table 1 to Table 2. The same Product No will have 1 value, the other value is 0. The result for Column Quantity should be like this:
Table 2:
Product No Grade Quantity A Good 1 A Normal 0 A Bad 0 B Good 2 B Bad 0 C Good 3 C Normal 0 C Bad 0
Within the LinkingID, there are duplicates in ID1 and ID2 but just in opposite columns. I have been trying to figure out a way to remove these set based. It doesn't matter which duplicate is removed. Essentially these are just endpoints and I don't care which side they are on. The solution must recognize the duplicates and not just remove based on every 2nd row.
I have a bunch of contacts that I've scored how well their names match to other contacts in the same business. I can programmatically figure out how to parse the results, but would like to know how to do this via SQL. My problem is for Business_fk 968976 I have 7 contacts. In the end I should have 4 contacts based on name match. For the business key listed Gerardo Lopez is in the ContactScore table twice for Contact keys 7355719 and 57028145. I then have two rows like so:
Each reference each other, and 2 is a good case, a more difficult case would have key 1 listed 10 times showing a ContactMatch_fk of 2 - 11, and then Contact_fk 2 listed 10 times with a ContactMatch_fk of 1, 3-11.I know 57028145 maps to 7355719 from the first row in the ContactScore table, so when Contact_fk of 7355719 comes up I should be able to skip it and not process that match. Hopefully that makes sense. Anyway here is the test data:
IF EXISTS (SELECT * FROM sys.objects WHERE object_id = OBJECT_ID(N'[dbo].[ContactScore]') AND type in (N'U')) DROP TABLE [dbo].[ContactScore]; GO CREATE TABLE [dbo].[ContactScore] ( [ContactScore_pk]INT NOT NULL, [Contact_fk]INT NOT NULL,
How can i perform this task with ssis OR TRANSACT SQL? I HAVE THESE ROWS WITH THE NEXT DATA, I want to take just the valid one, BUT I HAVE A LOT OF COMBINATIONS AS following names, it can be animals, things or personal names

Im working through the MS example of "removeDuplicates". I cant seem to figure out how to add custom property for input column.
I added the helper method: private static void AddIsKeyCustomPropertyToInput(IDTSInput90 input, object value) { IDTSCustomProperty90 isKey = input.CustomPropertyCollection.New(); isKey.Name = "IsKey"; isKey.Value = value; } I call it from: public override void ProvideComponentProperties() { //... AddIsKeyCustomPropertyToInput(input, false); //... } public override void ReinitializeMetaData() { IDTSInput90 input = ComponentMetaData.InputCollection[0]; if (input.CustomPropertyCollection.Count == 0) { AddIsKeyCustomPropertyToInput(input, false); } // ... }
However when I deployed it and added the component to SSIS package - I cant see the Custom Column "IsKey" in the input column properties window. What am I missing - please help
I have created a phone list and am using a union to be able to display letter category. However, what I would like to do is only show the letter category if their is an employee with the corresponding last name.
For example, if someone does not have a last name starting with "Z", then "Z" should not show up on my report.
SELECT LastName, FirstName, Dept, Phone UNION ALL
SELECT v.letter,NULL,NULL,NULL,NULL FROM (VALUES('A'),('B'),('C'),('D'),('E'),('F'),('G'),('H'),('I'),('J'),('K'),('L'),('M'),('N'),('O'),('P'),('Q'),('R'),('S'),('T'),('U'),('V'),('W'),('X'),('Y'),('Z')) AS v(letter) ORDER BY vchLastName, vchFirstName
I had Excel file input & import to DB Table by using Data flow in SSIS.but it had duplicates so I dont use the Dupe Records
So I planned like below:
Method 1: Here OLEDB Destination are Good Records(Without Duplicates) OLEDB Destination are Not Good Records(only Duplicates) or Method :2 If I add a column(GOOD_RECORD) in DB Table and Should I update '1' for top 1 record (for Good Record) and remaining as '0' for other Records (for Dups)latter I utilize Through flag of GOOD_RECORD
i.e.,, select * from DB_TABLE where GOOD_RECORD='1' .
I think that Method :2 Advisable for Performance/flexible but Here How can I update by using SSIS(Data flow) ????

What happens when you add the Ignore Case flag into the mix?
I'm having a hell of a time - I'm dealing with an SCD situation using TableDifference component and I have both existing dimensions and new data coming in, each go through identical Case-Insensitive/Sort with remove duplicates, but I'm getting identical new and deleted records detected - I think because of ordering issues. I'm still trying to whittle the test case down, but I think data from all around the records I'm investigating seems to get sorted in between them, so I'm having trouble getting a small test case built.
I think the mixed case data is the root of the problem, and I think the design is bad, but before I go back to the technical lead, I need to understand enough to show that you cannot take two pipelines sorted and de-duped case-insensitively and then do a case-sensitive table difference operation.
my table does not have primary key so i created a seperate index on each of the table.
I used the recommended tablediff utility and it works successfully. But its only show the difference of records in each table and does not copy rows from source to destination and destination to source table. I was expecting database1.dbo.table1 contains same records as in database1.dbo.table2.

Can you write a short script for my problem, just like comparison of database1.dbo.table1 compares in database2.dbo.table2 and which ever records not present it should copy those and vice-versa.
It means Database1.dbo.table1 contains 5 records Database2.dbo.table2 contains 5 records
Can some kind person out there please help me, I've been stuck on this for daaaa-y-s.
I have a database that allows users to search for pdf's of technical drawings.
Basically I have one huge table with multiple columns, which the user can only search on any combination of one of these two columns "drawing_series" eg 0100, 0046, 1000 "drawing_number" eg 0076000, 0000123, 0000004
There is also a Revision column(which the user can't see) that goes up by 1 each time a drawing has been modified and resubmitted to the database. "revision" eg 01, 02, 03, ....... 99
So a search on 0046 series might pull back drawings
The problem is that I only want drawings with the highest revisions returned eg
0046-0010000-03 0046-0076000-01 0046-0076888-02
The code below worked like a charm in the test stages pulling back a few hundred records but now that i've uploaded 10's of thousands of records to the DB the whole lot dies if the search result pulls back more than a few thousand records.
SELECT * FROM dbo.Drawing_Database where dbo.Drawing_Database.revision=(select max(revision) from dbo.Drawing_Database self where self.drawing_series + self.drawing_number = dbo.Drawing_Database.drawing_series + dbo.Drawing_Database.drawing_number) Drawing_Series like '0046' order by Drawing_Series, Drawing_Number
There must be a simpler way of doing this as i can pull out duplicate series + numbers using " HAVING Count(*)>1" but dont know where to go from there.
Hi All,I am banging my head against a brick wall over this problem, so anyhelp in the correct direction would be muchly appreciated!I have 2 SQL (MS SQL) server tables, realated to -a Property,Sales of that property.A property is uniquely identifed by its Roll, valuation Number andSuffix (not my choosing).Each property can only appear in the property table once, and can onlyhave 1 assessment - but can have multiple sales (ie - over theannalysis period the same property can sell more than once).There is approximatly 19000 properties relating to about 8000 sales.When creating a query to list property and most recent sale (if thereis any) I end up with somthing like this -SELECT [roll], [valuation], [suffix], [sale date]FROM [property]LEFT JOIN [sales]ON[property].[roll] = [sales].[roll] AND[property].[valuation] = [sales].[valuation] AND[property].[suffix] = [sales].[suffix](table names simplifed).I get rows where there is all the property data there, but sale date(etc.) is null (as I would expect from a left join), but the problem is- when there is more than 1 sale for a property it pulls out anothercopy of the property data.In short, because of that I come out with more records than properties.ie -roll valuation suffix sale date12 456789 A 1/1/200312 788988 B NULL14 123456 A 1/1/200314 123456 A 1/1/2004(Note - the last two are the same property).I didn't know that the left join can affect both joined tables!Is there any way around this? Any suggestions/hints in the rightdirection would be very much appreciated!THANKS!

Person can have more than one start/end date therefore I get multiple of the same row ID and Person ID when looking at their dates.
I want to display the most recent end date and associated data if there is more than one start/end date for the same person. I decided to do a self join with max Date aggregate using this against a main select from the Table1:
SELECT PersonID, MAX([End Date]) AS MaxEndDate FROM Table1 GROUP BY PersonID
And join it this way:
select RowID, PersonID, [End Date] FROM Table1 INNER JOIN ( SELECT PersonID, MAX([End Date]) AS MaxEndDate
[Code] ....
When I run the sub-query on its own it gives me the single PersonID and Max Date but on self-joining with Table1 I still get the duplicates values.
Trying to cross-update 2 tables. Picture a checkbook reconcilliation without common check numbers. The checkbook has uniqueids and the bank has transaction ids but they are different. So the match is on date/payee and amount. So I wrote 2 checks to the same person, on the same day, for the same amount but forgot to enter one in the register.
when i run the update statement: update b set b.bankid=c.myid from checks c join bank b on c.cdate=b.cdate and c.payee=b.payee and c.cost=b.cost
Both bank statement records would be updated to my one check record [can't happen] Also: this will be running on a hundred thousand records per month with potential for duplication/ommission on either side.
