I have a table that contains some duplicate records. The entire record is not duplicated, but there are two fields which if both are duplicated, result in what I call a duplicate record. I can see that I have these duplicates by doing the following:
SELECT DISTINCT ReferenceNumber, ShipToCompanyID
FROM tabMedia
WHERE (MediaTypeID = '1') AND (FinishDate > '2011-01-01')
GROUP BY ReferenceNumber, ShipToCompanyID
HAVING (COUNT(ReferenceNumber) > 1) AND (COUNT(ShipToCompanyID) > 1)
ORDER BY ReferenceNumber
but of course, this only returns two fields. I need the entire record returned where the duplicate exists...
writing the query for the following, I need to collapse the continuity. If the termdate for an ID is one day less than the effdate of the next id (for the same ID) i need to collapse the records. See below example .....how should i write the query which will give me the desired output. i.e., get min(effdate) and max(termdate) if termdate is one day less than the effdate of next record.
Using Transact-SQL how can I copy all fields except one from one record to another? The field in question being the identity field. Since, this field cannot be duplicated a simple INSERT statement fails. How can I specify an exclusion list of fields?
I'm designing an app for stock keeping. In my DB, I have a field called "ItemSerialNo" and I made it unique(but not the table's primary key). On my front end, I have a text box for Item Serial No and a combo box loaded with the item brands and also a save button. I know that if I try to save a serial no already existing in my DB, the app won't allow me because of the unique property of the field named "ItemSerialNo". But I want to be able to save a serial no already existing in my DB but with a different brand name.
For example, I want to be able to save information like:
1. ITEM SERIAL NO = 12345 BRAND NAME = AA 2. ITEM SERIAL NO = 12345 BRAND NAME = BB.
I have a result set stored in a temporary table variable. The fields need to have heirarchy when they finaly get displayed to the user. I need to replace the repeating fields per group with NULL and leave out only one set of unique records per group.
I want to do something like this- make the fields in red NULL while leaving out the ones in green.
ValB ValB2 ValB3 ValB40 ValA50 { Row. Group B ValB ValB2 ValB3 ValB41 ValA51 }
I was able to achieve this by using @@ROWCOUNT with in a while loop by performing one UPDATE at a time (SET ROWCOUNT = 1). But i have to run Count(*) each time I loop through the update query to figure out the remaining number of rows I have per group as I need to leave out one untouched. But the Count function is taking too much time and I'm having performace issues.
Any idea how I might be able to do this in my stored proc. efficiently?
hi, I've done Googling and forum hunting but haven't had success finding a simple answer... My table schema is such that it requires the (int) LinkedItemID field to be nullable but still those fields which are set must not be duplicates. I see constraint is out of question and also identity doesn't seem to fit since I'm not using autofill for this particular field. Is there some other way doing this on Sql Server 2005?
I'm looking for the correct syntax to pull back duplicate vendors based on 6 fields from two different tables. I want to actually see the duplicate vendor information (not just a count). I am able to pull this for one of the tables, something like below:
select * from VendTable1 a join ( select firstname, lastname from VendTable1 group by firstname, lastname having count(*) > 1 ) b on a.firstname = b.firstname and a.lastname = b.lastname
I'm running into issues when trying to add the other table with the 4 other fields.
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.
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 someone tell me the best procedure when trying to find duplicate records within a table(s)?
I'm new using SQL server and I have been informed that there maybe some DUPS within unknown tables. I need to find these DUPS.
If someone can tell me how to perform this procedure I would apprciate it. And if you reply can also include examples that i could follow for my records.
Table1 has shop# and shop_id. Every shop# should have only one shop_ID. There has been a few data entry errors where a shop# has duplicate a shop_id. How to write a query for shop#s that have more than one shop_id?
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?
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

How can I made a query to show only my duplicate records ? For some reason that i do not know, i have duplicate entries in my clustered index 21 duplicate records in a table how can i query to know those 21 duplicate records ?
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”
