SqlBulkCopy Issues With Duplicate Records
Sep 14, 2006
SqlBulkCopy does not seem to have much flexibility.
If your table has columns that dont allow duplicates, you are apparently screwed. Its a shame there is no switch or param setting you can issue the SqlBulkCopy class (if there is, please let me know!!)
Example:
Say I have a table "Cars" with fields "CarId" (identity) and "CarName" (varchar) and the CarName field has a unique constraint. Now, I have a DataTable that contains a bunch of CarNames to insert. If there are duplicates on CarName, the entire insert fails. This is nothing to do with the PK or identity field.
The problem I have: I would much rather have an option to ignore or silently not insert that duplicate row, but continue to insert the rest of my data.
Any known work arounds for this would be much appreciated. Maybe I am missing something?

I'm looking at SSIS and SqlBulkCopy as a possible method to quickly insert and process large amounts of data, my current method uses the sp_xml_preparedocument and OPENXML to parse an xml document of the data I want to process and insert into the database, however I'm noticing the performance of SqlServer parsing the xml document isn't that good.
I found the C# SqlBulkCopy method (new in .NET 2.0) and I was thinking it would be faster to use that to load my data into a staging table and then use SSIS to extract the data from the staging table, process and transform it as necessary and finally load it into the final destination tables. I was able to create an Integration Services Project that selects the data from the staging table, does a bit of processing on one of the fields (by calling a stored procedure), and finally loads the processed data into the final table.
The problem with this is I need to clean out the rows that were extracted from the staging table and I'm not sure how I can accomplish this (and I can't just issue a "delete from staging_table" because there maybe new records in the staging table that were not processed), perhaps I can either delete each record as it is proccessed or somehow get the last proccessed identity id from the staging table and delete all records less than or equal to that id.
thanks in advance for any help you can provide, maybe there is an easy way to accomplish what I'm trying to do.

Yes, I know this subject has been exhausted, but I need help in locating the discussion which took place a few months ago.
Sharon relayed to the group a piece of software (expensive) which would help in my particular situation. I grabbed a demo and have gotten the approval for purchase. Unfortunately, I don't have the thread with me at work.
The problem:
Number Fname Lname Age ID
123 John Franklin 43 1
123 Jane Franklin 40 2
123 Jeff Franklin 12 3
124 Jean Simmons 39 4
125 Gary Bender 37 5
126 Fred Johnson 29 6
126 Fred Johnson 39 7
127 Gene Simmons 47 8
The idea would be to get only unique records from the Number column. I don't care about which information I grab from the other columns, but I must have those fields included.
If my resultant result set looked as follows, that would be fine. Or any other way, as long as all of the fields had information and there were only unique values in the Number field.
Number Fname Lname Age ID
123 Jeff Franklin 12 3
124 Jean Simmons 39 4
125 Gary Bender 37 5
126 Fred Johnson 39 7
127 Gene Simmons 47 8
If anyone remembers this discussion, mainly the date, I would really appreciate it.
Thanks

I have two tables, one contains all work orders, the second contains records on work orders that are linked to customoer orders. I'm trying to create a query that will return specific fields from the table that contains orders in the linked order table, and only the work orders in the all order table that (work_order) do not exist in the linked order table (demand_supply_link). I have tried several queries and cannot get the results I desire. Here is the query I am currently trying.
SELECT DISTINCT WORK_ORDER.DESIRED_WANT_DATE as 'Want Date', DEMAND_SUPPLY_LINK.SUPPLY_BASE_ID as 'WO Id',
WORK_ORDER.DESIRED_QTY as 'End Qty', DEMAND_SUPPLY_LINK.SUPPLY_PART_ID as 'Part Id', CUST_ORDER_LINE.CUSTOMER_PART_ID as 'Cust Part',
OPERATION.RESOURCE_ID as Resource, PART.DESCRIPTION as Description, CUSTOMER.NAME as Name
FROM ((((DEMAND_SUPPLY_LINK INNER JOIN CUST_ORDER_LINE ON DEMAND_SUPPLY_LINK.DEMAND_BASE_ID = CUST_ORDER_LINE.CUST_ORDER_ID)
INNER JOIN WORK_ORDER ON DEMAND_SUPPLY_LINK.SUPPLY_BASE_ID = WORK_ORDER.BASE_ID)
INNER JOIN OPERATION ON WORK_ORDER.BASE_ID = OPERATION.WORKORDER_BASE_ID) INNER JOIN PART ON WORK_ORDER.PART_ID = PART.ID)
INNER JOIN (CUSTOMER INNER JOIN CUSTOMER_ORDER ON CUSTOMER.ID = CUSTOMER_ORDER.CUSTOMER_ID) ON CUST_ORDER_LINE.CUST_ORDER_ID = CUSTOMER_ORDER.ID
WHERE WORK_ORDER.DESIRED_WANT_DATE Is Not Null AND OPERATION.RESOURCE_ID in ('ASSY','FAB 1','PLAY TRK')
AND WORK_ORDER.STATUS='R'
UNION
SELECT distinct work_order.desired_want_date as 'Want Date', work_order.BASE_id as 'WO Id',
work_order.desired_qty as 'End Qty', work_order.part_id as 'Part Id', operation.resource_id as Resource,
part.description as Description
FROM WORK_ORDER INNER JOIN PART ON PART_ID=WORK_ORDER.PART_ID INNER JOIN OPERATION ON WORK_ORDER.BASE_ID=OPERATION.WORKORDER_BASE_ID
WHERE WORK_ORDER.DESIRED_WANT_DATE IS NOT NULL AND OPERATION.RESOURCE_ID IN ('ASSY','FAB 1', 'PLAY TRK')
AND WORK_ORDER.STATUS='R'
This is the error I receive:
Server: Msg 205, Level 16, State 1, Line 1
All queries in an SQL statement containing a UNION operator must have an equal number of expressions in their target lists.
The all orders table (work_order) will not have the other fields to link to as there is no customer order linked to them.
Can anyone help. Thanks!

Hi,
Not so sure how simple this question is but here is what happened. I installed SQL Server 2005 on a new Win Server 2003. I exported the tables and their data from the old machine to the newly established database on the new machine.
It looks like all my records were duplicated. When I try to delete one of the duplicates it won't work because both rows are effected. I can't set my primary key now and if I try to create a new database with the primary key already set than the import fails.
Any one run into this before or know what's going on?
Any help ASAP would really be appreciated.
Thanks,
Alice

Hi,I have written a web application using dreamweaver MX, asp.net, and MSsql server 2005.The problem I am having occurs when I attempt to edit a record. I have setup a datagrid with freeform fields so that the user can click on edit, make the required changes within the data grid then click update. The data is then saved to the database. All this was created using dreameaver and most of the code was automatically generated for me.The problem is that, not everytime, but sometimes when I go to edit a record once I hit the update button to save the changes the record is duplicated 1 or more times. This doesnt happen everytime but when it does it duplicates the record between 1 and about 5 times. I have double checked everything but cannot find anything obvious that may be causing this issue. Does anyone have any suggestions as to what I should look for? Is this a coding error or something wrong with MSsql? Any ideas?Thanks in advance-Mitch

hi,
I am trying to fetch data from 2 tables, say TABLE1 and TABLE2, both of which got columns like id and num. Then i want all the rows from TABLE1 where id1=id2 and num1 != num2.
but it is showing all the rows for an id1 twice, if there are two records in TABLE2 with same id and num.
is there any way to filter those records without using the distinct keyword.
regards
Rajeev.

Sorry for the new thread.
I have a userprofile table. There are a lot of duplicate records in this table. e.g.
USERID-----LASTNAME---EMAILADDRESS----CREATEDATE
----------------------------------------------------------------------
1----------A-----------A@yahoo.com---------2000-09-05 16:07:00.000
2----------A-----------A@yahoo.com---------2000-09-10 16:07:00.000
3----------A-----------A@yahoo.com---------2000-09-15 16:07:00.000
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)

Hello board,
I was wondering if anyone can tell me an easy way to find duplicate records on sql. The thing is this, at work we have a database (table) which includes tracking numbers, I need a easy way to be able to search this table for duplicate tracking numbers and print them out. I currently access this table to edit some data by using the following path “Start > Programs > Microsoft SQL Server > Enterprise Manager” then work my down the tree to “Databases > Master > Tables” on tables I do a right click and “open table/query”. Any help would be most appreciated. Believe me I’m very “SQL illiterate”
