I'm trying to clean up a database design and I'm in a situation to where two tables need a FK but since it didn't exist before there are orphaned records.
Tables are:
Brokers and it's PK is BID
The 2nd table is Broker_Rates which also has a BID table.
I'm trying to figure out a t-sql statement that will parse through all the recrods in the Broker_Rates table and delete the record if there isn't a match for the BID record in the brokers table.
I know this isn't correct syntax but should hopefully clear up what I'm asking
Hi All,I have a table in SQL Server 2000 that contains several million memberids. Some of these member ids are duplicated in the table, and eachrecord is tagged with a 1 or a 2 in [recsrc] to indicate where theycame from.I want to remove all member ids records from the table that have arecsrc of 1 where the same member id also exists in the table with arecsrc of 2.So, if the member id has a recsrc of 1, and no other record exists inthe table with the same member id and a recsrc of 2, I want it leftuntouched.So, in a theortetical dataset of member id and recsrc:0001, 10002, 20001, 20003, 10004, 2I am looking to only delete the first record, because it has a recsrcof 1 and there is another record in the table with the same member idand a recsrc of 2.I'd very much appreciate it if someone could help me achieve this!Much warmth,Murray
I need to identify duplicate records in a table. TableA [ id, firstname, surname] I’d like to see records that may be duplicates, meaning both firstname and surname are the same and would like to know how many times they appear in the table
I’m not sure how to write this query, can someone help? Thanks in advance!
I use a tabel for storin log data from a mail server. I noticed that I'm getting duplicate records, is there a way to delete the socond and/or third entry so I dont have any duplicates?
Userid is auto number, lastname and emailaddress are PK.
I want to delete duplicate records. If lastname and emailaddress are the same, only keep a record which createdate is the most newest date. See above example I only want to the record which userid is 3. I have alreday created a code which I attached below. This code onle keep a record which userid is 1.
Anybody can help me to solve this problem? Thanks.
============== My current code ==================== delete from userprofile where userprofile.userid in --list all rows that have duplicates (select p.userid from userprofile as p where exists (select lastname, emailaddress from userprofile where lastname = p.lastname and emailaddress = p.emailaddress group by lastname, emailaddress having count (userid)>1)) and userprofile.userid not in --list on row from each set of duplicate (select min(p.userid) from userprofile as p where exists (select lastname, emailaddress from userprofile where lastname = p.lastname and emailaddress = p.emailaddress group by lastname, emailaddress having count (userid)>1) group by lastname, emailaddress)
CAN ANYBODY REPLY FOLLOWING QUESTIONS. I WANT TO DELETE DUPLICATE ROWS IN MY TABLE WITHOUT USING TRANSACTION TABLE. AND ONE MORE QUESTION HOW TO GET YESTERDAY DATE BY USING ISQL WINDOW.
I have several rows in a table that contain duplicate information. I want to trim them down to one instance per row, without other duplicates.
I have several columns, but only 2 of the columns are used to determine the "Identical Rows", however one of the other columns could also be used to determine which of the others are deleted.
Let's just say I have a table called DATA. In DATA I have the following columns: C1: ID/Key column (Unique numbers not associated with any other row) C2: Specific Data column 1 C3: Specific Data Column 2 C3: Keeper if not null C4: Misc Info C5: Misc Info
Basically IF C2 & C3 are duplicated, then I want to keep one of these and ditch the others.
The row I want to keep is the one that has info in C4, but at times C4 does not have anything in it on any of them, at that point I just care about keeping one of the C2 & C3 Duplicate rows.
The other issue I face is C2 will always have something in it, but at times C3 will not and C4 will.
So I want to keep the one duplicate row that has the most info in it. At minimum, I want to always keep C2 & C3 if they both contain data.
For example, if I had the following duplicate rows: (C2) red (C3) 123 (C4) XYZ (C2) red (C3) 123 (C4) XYZ (C2) red (C3) 123 (C4) XYZ (C2) red (C3) (C4) XYZ (C2) red (C3) 123 (C4)
I want to keep: (C2) red (C3) 123 (C4) XYZ
I have some rows that have three exact duplicates, some that have four, some that have two.
How can I tell the Query Manager to delete all but one instance of each duplicate row?
I did do a query to find out how many duplicates I have and found it to be around 232,000+. Basically I will be cutting this in half if I can get rid of the duplicates.
I have read 30 different ways on many sites and I am now officially confused
I am trying to delete the duplicates from a table, but keep 1 of the records.
Here is my query which works on smaller tables <2000 records, but the query either timeouts or just runs and runs on larger tables >50,000 and >150,000.
DELETE FROM Table1 WHERE Table1.ID IN
/* LIST 1 - all rows that have duplicates*/ (SELECT F.ID FROM Table1 AS F WHERE EXISTS ( SELECT computerName, programName, version, publisher, Count(ID) FROM Table1 WHERE Table1.computerName = F.computerName AND Table1.programName = F.programName AND Table1.version = F.version AND Table1.publisher = F.publisher GROUP BY Table1.computerName, Table1.programName, Table1.version, Table1.publisher HAVING Count(Table1.ID) > 1)) AND Table1.ID NOT IN
/* LIST 2 - one row from each set of duplicate*/ (SELECT Min(ID) FROM Table1 AS F WHERE EXISTS ( SELECT computerName, programName, version, publisher, Count(ID) FROM Table1 WHERE Table1.computerName = F.computerName AND Table1.programName = F.programName AND Table1.version = F.version AND Table1.publisher = F.publisher GROUP BY Table1.computerName, Table1.programName, Table1.version, Table1.publisher HAVING Count(Table1.ID) > 1) GROUP BY computerName, programName, version, publisher);

The duplicate records i am trying to delete are not truly duplicates, each record has a unique ID and install dates could vary. I am trying to identify duplicate records as identical (computerName + programName + version + publisher) See records 1 and 4 in table structure above... i dont care which of the duplicates is kept, as long as 1 is kept.
What I am looking for is either a completely new query which maybe optimized to run on a larger scale table or maybe just a performance tweak to my exisitng query??
I have a little dilemma. I have a table ALLTABLE that has duplicate records and I want to delete them. ALLTABLE has these columns with these values for example:
As you can see there is some duplicates in the first 3 rows and the final 2 (the entity number is the only difference). I want the table to look like this:
Policy Premium Class State Entity Number ADC-WC-0010005-0 25476 63 31 1 ADC-WC-0010005-0 1457 63 29 4 ADC-WC-0010092-1 2322 63 37 1 ADC-WC-0010344-0 515 63 01 1
Thank you so much for the help. It is really appreciated.

I wrote this to show for example in my real table have 50000 rows and 1751 duplicate rows.
This is part of my trigger on table T1. I am trying to check if the records inserted to T1 is available in myDB.dbo.myTable or not (destination table). If it is available rollback T1. It does not do that although I insert the same records twice.
-- duplicate record check SET @step = 'Duplicate record' IF EXISTS ( SELECT i.myID, i.Type FROM INSERTED i INNER JOIN myDB.dbo.myTable c ON i.myID = c.myID GROUP BY i.myID, i.Type HAVING (COUNT(*) > 1) AND (i.Type = 'In') ) BEGIN ROLLBACK transaction RAISERROR('Error: step: %s. rollback is done.', 16, 1, @step) Return END
Hi EverybodyThis Code duplicate the record in the database, can somebody help me understand why that happen.

In order to check that a new users ID does not already exist in the database I thought it would be a good idea to put the Insert into a Try Catch statement so that I can test for the duplicate record exception and inform the user accordingly. I was also trying to avoid querying the data base before executing the Insert.
The problem is what to actually test for. When the code throws the exception it is a big long string . .
"Violation of PRIMARY KEY constraint 'PK_Users_2__51'. Cannot insert duplicate key in object 'Users'"
I just thought that there has to be something simplar to test for than comparing the exception to the above string.
Can anyone tell me of a better way of doing this ?
(by the way I am only using Web Matrix and MSDE in case it matters)
I am working on a web application that utilizes a sql server database. One of the tables is a large text file that is imported through a DTS package from a Unix server. For whatever reason, the Unix box dumps quite a few duplicate records in the nightly run and these are in turn pulled into the table. I need to get rid of these duplicates, but can't seem to get a workable solution. the query that is needed to get the records is:SELECT tblAppointments.PatientID, tblPTDEMO2.MRNumber, tblAppointments.PatientFirstName, tblAppointments.PatientLastName, tblAppointments.PatientDOB, tblAppointments.PatientSex, tblAppointments.NewPatient, tblAppointments.HomePhone, tblAppointments.WorkPhone, tblAppointments.Insurance1, tblPTDEMO2.Ins1CertNmbr, tblAppointments.Insurance2, tblPTDEMO2.Ins2CertNmbr, tblAppointments.Insurance3, tblPTDEMO2.Ins3CertNmbr, tblAppointments.ApptDate, tblAppointments.ApptTimeFROM tblAppointments CROSS JOIN tblPTDEMO2WHERE (tblAppointments.PatientID = tblPTDEMO2.MRNumber)AND tblAppointments.Insurance1 = 'MED'AND tblAppointments.ApptTypeID <> 'MTG'AND tblAppointments.ApptTypeID <> 'PNV'AND DateDiff("dd", ApptDate, GetDate()) = 0Order By tblAppointments.ApptDateMy first thought was to try to get a Select DISTINCT to work, but couldn't figure out how to do this with the query. My next thought was to try to set up constraints on the table, but, since there are duplicates, the DTS package fails. I assume there is a way to set up the transformations in a way to get this to work, but I'm not enough of an expert with SQL Server to figure this out on my own. I guess the other way to do this is to write some small script or application to do this, but I suspect there must be an easier way for those who know what they are doing. Any help on this topic would be greatly appreciated. Thanks.
So I'm working on updating and normalizing an old database, and I have some duplicate records that I can't seem to get rid of. Every column is identical, right down to what is supposed to be the key. I can't right a delete query to just isolate one row, and I can't delete (or even udpate) any row in management studio. Any thoughts on how to remove the extra rows?
There is a field that's supposed to be unique, so I can write a simple query to get all of the problem rows. The only thing is that they come back in pairs.

I want to Update one of the duplicate row as I don't have any unique id column. So can anybody update one of the the duplicate record without using any id or altering any column.
