Hi everybody I need help on finding duplicates and deleting the duplicate record depending on name and fname , deleting the duplicates and leaving only the first one.
my PERSON table is this below:
ID name fname ownerid id2
1 a b
2 c c
3 e f
4 a b 1 10
5 c c 2 11
I have this query below that returns records 1 and 4 and 2 and 5 since they have the same name and fname
select * from ( Select name ,fname, count(1) as cnt from PERSON group by
name,Fname ) where cnt > 1
ID name fname ownerid id2
1 a b
4 a b 1 10
2 c c
5 c c 2 11
With this result I need to delete the second record of each group but update the first records with the ownerid and id2 of the second record that would be deleted... I don't know how to proceed with this..
Some guy posted that the syntax: delete top 1 from some_table works for deleting duplicates. I am pretty sure that doesnt work but I wanted to check just in case it did because it would be a really easy to delete duplicates.
Hi i need a query to check a table and if any duplicates of the column called "MessageID" and if there are any duplicates then delete them leaving just the one unique MessageID
so i have
MessageID, Number, Text.

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
I am trying to find when a name has been entered more than once into 1 database table.
I'm currently doing something like this (can't remember exactly, not at work)
SELECT COUNT(*) AS Cnt, Name FROM tblTable GROUP BY Name ORDER BY Cnt Desc
This brings back all the Names in the database and tells me which are duplicates but I want to just have the results of the duplicate values and not the single values.
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;
Hi.I have a "union" table which results of a union of two tables.Occasionally I could have duplicates, when the same PIN has been addedto both tables, albeit at different Datees/Times, such as:PINNameAdded Date100411A7/11/2007 10:12:58 AM100411A7/17/2007 10:54:23 AM100413B7/11/2007 10:13:28 AM100413B7/17/2007 10:54:39 AM104229C7/6/2007 2:34:13 PM104231D7/6/2007 2:34:25 PM104869E6/10/2007 11:59:12 AM104869E6/22/2007 2:40:18 PMThe question is - how can I delete by queries the first occurence(time-wise) of these duplicates - i.e. I would want to delete thefirst occurence of 100411 (A), the first occurence of 100413 (B), andthe first occurence of 104869 (E) in the example above - records C andD show only once, so they are fine.Is there a MsAccess solution ? Is there a SQL-server solution ?Thank you very much !Alex
I have a DELETE statement that deletes duplicate data from a table. Ittakes a long time to execute, so I thought I'd seek advice here. Thestructure of the table is little funny. The following is NOT the table,but the representation of the data in the table:+-----------+| a | b |+-----+-----+| 123 | 234 || 345 | 456 || 123 | 123 |+-----+-----+As you can see, the data is tabular. This is how it is stored in the table:+-----+-----------+------------+| Row | FieldName | FieldValue |+-----+-----------+------------+| 1 | a | 123 || 1 | b | 234 || 2 | a | 345 || 2 | b | 456 || 3 | a | 123 || 3 | b | 234 |+-----+-----------+------------+What I need is to delete all records having the same "Row" when there existsthe same set of records with a different (smaller, to be precise) "Row".Using the example above, what I need to get is:+-----+-----------+------------+| Row | FieldName | FieldValue |+-----+-----------+------------+| 1 | a | 123 || 1 | b | 234 || 2 | a | 345 || 2 | b | 456 |+-----+-----------+------------+A slow way of doing this seem to be:DELETE FROM XWHERE Row IN(SELECT DISTINCT Row FROM X x1WHERE EXISTS(SELECT * FROM X x2WHERE x2.Row < x1.RowAND NOT EXISTS(SELECT * FROM X x3WHERE x3.Row = x2.RowAND x3.FieldName = x2.FieldNameAND x3.FieldValue <> x1.FieldValue)))Can this be done faster, better, and cheaper?
Serial Count 001 2 the count is 2 because Serial 001 has an MSDSID of 20 and 22 002 1 the count is 1 because Serial 002 only has MSDSID 21 003 2 the count is 2 because Serial 003 has an MSDSID of 21 and 22 004 1 the count is 1 because Serial 002 only has MSDSID 23
It would be even better if the results just showed where the count is greater than 1.
I have a table employee_test having the sample data. The rows with EmployeeID=6 are duplicate rows. I want to delete the duplicates retaining one row for the employeeid=6. Note :- I don't want to use a temporary table. I want to do this using a single query or at the most in a SP query batch. Please advise.
I have this query below that I created to do a count, but I don't think this is what I needed.
I need to find the duplicates. Example, if
CLI_ID1 12345 has 4 CLIP records, each CLIP record should have a different CLIP rank. I need to find scenarios where 2 (or more) of the CLIP records have the same CLIP RANK. If there are duplicate CLIP_RANKs within the same CLI_ID,
Select Distinct cli_id1, count(clip_rank) countrank FROM impact.dbo.CLI LEFT JOIN impact.dbo.CLIO ON CLI.CLI_ID1 = CLIO.clio_id1
left join impact.dbo.clip ON cli_id1 = clip_id1 Where (clio_trm = '' or clio_trm = NULL or clio_trm is null) group by cli_id1 order by cli_id1
I need to make a selection on join datasets with 2 conditions and populate the results in another dataset(Report).It is working with the fist condition "AccountingTypeCharacteristicCodeId = 3"...
Auto_ID Account_ID Account_Name Account_Contact Priority 1 3453463 Tire Co Doug 1 2 4363763 Computers Inc Sam 1 3 7857433 Safety First Heather 1 4 2326743 Car Dept Clark 1 5 2342567 Sales Force Amy 1 6 4363763 Computers Inc Jamie 2 7 2326743 Car Dept Jenn 2
I'm trying to delete all duplicate Account_IDs, but only for the highest priority (in this case it would be the lowest number).
I know the following would delete duplicate Account_IDs:
DELETE FROM staging_account WHERE auto_id NOT IN (SELECT MAX(auto_id) FROM staging_account GROUP BY account_id)
The problem is this doesn't take into account the priority; in the above example I would want to keep auto_ids 2 and 4 because they have a higher priority (1) than auto_ids 6 and 7 (priority 2).
How can I take priority into account and still remove duplicates in this scenario?
Every sunday, new data will be loaded from temptable to main table. I have to make sure that, duplicates does not get loaded from temptable to maintable.
For example, if last sunday a record gets loaded from temp to main. If this sunday also the same record is present then it means that is a duplicate.
The duplicate is decided on below scenario
select 'CodeChanges: ', count(*) from CodeChanges a, CodeChanges_Temp b where a.AccountNumber = b.AccountNumber and a.HexaNumber = b.HexaNumber and a.HexaEffDate = b.HexaEffDate and a.HexaId = b.HexaId and
[Code] ...
Yesterday (Sunday) , data from temp got loaded onto maintable but with duplicates.
There is a log which just displays number of duplicates.
Yesterday the log displayed 8 duplicates found. I need to find out the 8 duplicates which got loaded yesterday and delete it off from main table.
There is a column in both tables which is 'creation date and time'. Every Sunday when the load happens this column will have that day's date .
Now i need to find out what are all the duplicates which got loaded on this sunday.
The total rows in temp table is : 363 No of duplicates present is : 8
I used below query to find out the duplicates but it is returning all the 363 rows from the maintable instead of the 8 duplicates.
Select 'CodeChanges: ', * from CodeChanges a where exists ( Select 1 from CodeChanges_Temp b where a.HexaNumber = b.HexaNumber and a.HexaEffDate = b.HexaEffDate and
[Code] ...
Need finding the duplicate records which has creation date time as '2015-11-01 00:00:00.000' and all the above columns mentioned in the query matches.
My basic situation is this - I ONLY want duplicates, so the oppositeof DISTINCT:I have two tables. Ordinarily, Table1ColumnA corresponds in a one toone ratio with Table2ColumnB through a shared variable. So if I queryTableB using the shared variable, there really should only be onrecord returned. In essence, if I run this and return TWO rows, it isvery bad:select * from TableB where SharedVariable = 1234I know how to join the tables on a single record to see if this is thecase with one record, but I need to find out how many, among possiblymillions of records this affects.Every record in Table1ColumnA (and also the shared variable) will beunique. There is another column in Table1 (I'll call itTable1ColumnC) that will be duplicated if the record in Table2 is aduplicate, so I am trying to use that to filter my results in Table1.I am looking to see how many from Table1 map to DUPLICATE instances inTable2.I need to be able to say, in effect, "how many unique records inTable1ColumnA that have a duplicate in Table1ColumnC also have aduplicate in Table2ColumnB?"Thanks if anyone can help!-- aknoch
I have a patient record and emergency contact information. I need to find duplicate phone numbers in emergency contact table based on relationship type (RelationType0 between emergency contact and patient. For example, if patient was a child and has mother listed twice with same number, I need to filter these records. The case would be true if there was a father listed, in any cases there should be one father or one mother listed for patient regardless. The link between patient and emergency contact is person_gu. If two siblings linked to same person_gu, there should be still one emergency contact listed.
Below is the schema structure:
Person_Info: PersonID, Person Info contains everyone (patient, vistor, Emergecy contact) First and last names Patient_Info: PatientID, table contains patient ID and other information Patient_PersonRelation: Person_ID, patientID, RelationType Address: Contains address of all person and patient (key PersonID) Phone: Contains phone # of everyone (key is personID)
The goal to find matching phone for same person based on relationship type (If siblings, then only list one record for parent because the matching phones are not duplicates).
I am new to SQL and SQL Server world. There must be a simple solutionto this, but I'm not seeing it. I am trying to create a crystalreport (v8.5) using a stored procedure from SQL Server (v2000) inorder to report from two databases and to enable parameters.When I create the stored procedure, it joins multiple one-to-manyrelationship tables. This results in repeated/duplicate records. Isthis an issue that should be solved within the stored procedure, or isthis inevitable? If latter, how do you eliminate the duplicates inCrystal Reports?Let's say we have three different tables - Event, Food, Equipment.Each event may have multiple food and multiple equipments; some eventsmay not have food and/or equipments. The stored procedure outcome maylook like this:Event Food Food_Qty EquipmentEquipment_QtyEvent1 Food2 10 Equipment51Event1 Food4 10NULL NULLEvent2 Food4 50 Equipment210Event2 Food4 50 Equipment52Event2 Food1 12 Equipment210Event2 Food1 12 Equipment52As you can see in Event2, for each Food variations, Equipment valuesrepeat. When I am creating a Crystal Reports, I have the duplicationproblem.What I would like to see in the report is either:Event1Food2, 10 Equipment5, 1Food4, 10Event2Food4, 50 Equipment2, 10Food1, 12 Equipment5, 2OR:Event1Food2, 10Food4, 10Equipment5, 1Event2Food4, 50Food1, 12Equipment2, 10Equipment5, 2Attempt1: Using "Eliminate Duplicate Record" option does not work withthe Equipment section since CR does not recognize "Equipment2" in thethird line of the table and "Equipment2" in the fifth line of thetable as duplicates.Event1 Food2, 10 Equipment5, 1Food4, 10Event2 Food4, 50 Equipment2, 10Equipment5, 2Food1, 12 Equipment2, 10(duplication)Equipment5, 2(duplication)Attempt2: I created group for each category (Event, Food, Equipment),put the data in Group Headers and used "Suppress Section" to eliminateif the same equipments are listed more than once within the Foodgroup. This eliminated the duplication, but the items do not aligncorrectly.Event1 Food2, 10 Equipment5, 1Food4, 10Event2 Food4, 50 Equipment2, 10Equipment5, 2Food1, 12 (I want this to appear right below the'Food4, 50' line)I would really appreciate any suggestions! Thank you in advance.
I'm using Management Studio Express, is there a way to find out what relationships of a database have cascade delete set to true? Also is there a way to change the settings (properties) of a relattionship without having to delete it and add it back?
Hello there,Im not quiet sure this is the right forum, but what the...I got a database with eg. dates in..(Day-Month-Year)01-02-200802-02-2008 <-- Today03-02-2008 Then i want to find the date for yesterday, in this example 01-02-2008, and delete the record.. - How is this done?Hope you understand and can help me,Regards Jeppe Richardt
I've been handed a database with over 100 tables and told to find everywhere a cascade delete constraint exists. I could just go through every table by hand and check, but I think there must be an easier way, perhaps an sql query on the master db. Any thoughts?
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.

Hi,I'm tring to call a stored procedure i'v made from a DNN module, via .net control.When I try to execute this sql statement: EXEC my_proc_name 'prm_1', 'prm_2', ... the system displays this error: Could not find stored procedure ''. (including the trailings [".] chars :)I've tried to run the EXEC statement from SqlServerManagement Studio, and seems to works fine, but sometimes it displays the same error. So i've added the dbname and dbowner as prefix to my procedure name in the exec statement and then in SqlSrv ManStudio ALWAYS works, but in dnn it NEVER worked... Why? I think it could be a db permission problem but i'm not able to fix this trouble, since i'm not a db specialist and i don't know which contraint could give this problem. Also i've set to the ASPNET user the execute permissions for my procedure... nothing changes :( Shoud someone could help me? Note that I'm using a SqlDataSource object running the statement with the select() method (and by setting the appropriate SelectCommandType = SqlDataSourceCommandType.StoredProcedure ) and I'm using the 2005 sql server express Thank in advance,(/d

Hi, I am kinda stuck on a delete stored procedure in my project and I was wondering if you could give me a hand.
My table is like this: Image <----FKconstraint ----- ImageNote --------FKconstraint------>Note.
What I want to do is delete all the notes linkeds to and Image through ImageNote when I am calling the storedprocedure DeleteImage:
So far I did something like this:
DELETE FROM [ImageNote] WHERE [Image Id]=@Id DELETE FROM [Note] WHERE Id IN (SELECT [Note Id] FROM [ImageNote] WHERE [Image Id]=@Id)
DELETE FROM [Image] WHERE (Id = @Id) RETURN
Obvisouly the second DELETE statement won't work as ""SELECT [Note Id] FROM [ImageNote] WHERE [Image Id]=@Id"" won't return a thing at that time. However I have to delete ImageNote first due to the constraint.
A friend told me I should try a trigger, but perhaps there would be something easier to do with some kind of array?
