Track Duplication Of Records
May 20, 2002
Hello,
I have a table which consists of 27,000 of records. Among these records, there is one record which
is a duplication of another record.
Is there any way to track this record from the same table by the SQL statement ?
I have been advised to use the following statement but it does not help:
Select count(*) As Duplicate, columnname from tablename group by columnname
Scrolling 27,000 lines of records with bare eyes is very painful.
Any help is appreciated.
Cheers

Hi all,
I have a data of applicants. Everyday we dump this data into SQL server. Now I need to generate reports everyday so that we can track how many records get updated everyday. Now the thing is that the applicants are in various stages. So my reports need to track the how many applicants changed from stage "abc" to "pqr" and how many changed from "pqr" to "xyz". Now it is not necessary that all the records change stages everyday.
thanks in advance,
Rohit

Hi,
I have a table full of items which can be searched.
I also have another table with the ID of each item and columns for no of times details shown, no of times saved etc.
What I would like to do is increment a value in this second table for each item every time it is returned in a search.
What would be the best way to do this?
(Im using a Stored Procedure)
Thanks in advance,
Pete

HI
I have created a job to run a reporting services job which then named it in the job scheduler 354EEF12-404F-46BD-B54F-708B5027837F. I then renamed the job to Rpt ETL log.
However it I was surpised to see two emails come with reference to this report. It seems to have created another one with the long job names.
Is there any way to stop this as I would really like to name to schduled rpt jobs without it duplicating.
Many Thanks
Robert

Hello
I noticed a spelling mistake in the data in a column of several tables, I used the following syntax to alter the spelling:
UPDATE [dbo].[Prod_Cat] SET [ProdName]=N'merseyside' WHERE ProdName = 'mmserseyside'
The above code correctly updated the spelling error, but it also inserted a new row with the corrected data.
So I found myself with two Identical rows containing the corrected information. I had to manually delete the extra row. Because if I had put in a DELETE statement, I would have then lost both rows.
What do I need to do to prevent this happening next time. As I find that I need to update the names of some products, but I don't want to duplicate them.
Thanks
Lynn

Hi
I have a set of excel files that i need to export to sql2005 using ssis. Now the issue is that i have no idea about he data ie it may have duplication in the primary key column. If i export it as it is to sql server, it will cause me problems. Is there any way i can filter out the rows which have duplication in the primary key column?

Hi, I having a problem with my query...
I want to copy data from 4 different database to 1 database... but if the destination database have already the same Primary Key the copying stops/terminated and not copying others that is not yet in the destination...
I don't have knowledge in T-SQL like IF...ELSE
my database is SQL Server 2000 but i'm using SQL 2005 Express Management for the query...
What i'm doing is like this:
Use osa (Destination Database)
Go
DELETE FROM tblFaculty (*I'll delete first the datas to avoid duplication)
INSERT INTO tblFaculty (FacultyID, LastName, FirstName, MiddleName, Rank, DeptCode)
(SELECT FacultyID, LastName, FirstName, MiddleName, Rank, DeptCode FROM cislucena.dbo.tMasFaculty)
INSERT INTO tblFaculty (FacultyID, LastName, FirstName, MiddleName, Rank, DeptCode)
(SELECT FacultyID, LastName, FirstName, MiddleName, Rank, DeptCode FROM amapn.dbo.tMasFaculty)
INSERT INTO tblFaculty (FacultyID, LastName, FirstName, MiddleName, Rank, DeptCode)
(SELECT FacultyID, LastName, FirstName, MiddleName, Rank, DeptCode FROM abe.dbo.tMasFaculty)
INSERT INTO tblFaculty (FacultyID, LastName, FirstName, MiddleName, Rank, DeptCode)
(SELECT FacultyID, LastName, FirstName, MiddleName, Rank, DeptCode FROM aclc.dbo.tMasFaculty)
My problem is if the facultyID (PrimaryKey) which i'm copying is already on the destination which is osa, the copying stops/terminated regardless whether there is more to copy. On the 4 source database, there might data that other database also has. That's why the copying is terminated. All i want to do is to check first each FacultyID if it is already on the destination before copying it to avoid error or duplication of Primary Key so it won't terminate the copying.
How is this possible sir? Anyone care to help? Thanks in advance! More Power!
Best Regards

Hi All,
Scenario: De-duplication logic should pick one record from source and check with all the destination records and insert if not duplicate. Else raise error. There are average 8 to 10 lookup check for each logic path. Key fields used for de-duplication check are FirstName, LastName, DOB, Gender, SSN.
Issues:
· Since picking row by row and processing the performance is constrained.
· Since 8-10 comparison is done using lookup performance downstream. (Lookup is used without caching, if cashing is used the package is failing after sometimes as if memory is failing. Can we handle this memory problem?)
Please give some suggestion to improve the performance. Current performance is around 2500 records per hour, but there are 8 lac records in total to process.
I am looking for guidance on this issue. If someone can guide me on how to do it better it would help me a lot.
Thanks,
S Suresh

I have a table with many fields but there is a single field that I do not want duplicates. If I index this specific field preventing duplicates, the entire record does not append. (The field in question is not keyed).

Hello, everyone. I am having problems catching a data duplication issue. I hope I can get an answer in this forum. If not, I would appreciate it if someone can direct me to the right forum.
I am working on a vs2005 app which is connected to a sql2005 db. Precisely, I am working on a registration form. Users go to the registration page, enter the data, ie. name, address, email, etc. and submit to register to the site.
The INSERT query works like a charm. The only problem is that I am trying to reject registrations for which an email address was used. I put a constraint on the email field in the table and now if I try to register using an e-mail address that already exists in the database I get a violation error (only visible on the local machine) on the sql's email field, which is expected.
How can I catch that there is already an email address in the database and stop the execution of the code and possibly show a message to the user to use a different address?
Thank you for all your help.
Antonio

I am using Remote Data service to Query an Sql Server Database using MDAC. The Os in which server is loaded in Window 2003 and the MDAC 2.8 version is installed. Now I create a table X with identity column. Then when I try to insert records in that table using Insert into X select * from Y statement. The statement gets executed by when i check the X table I find that the duplicate records are present with different identity no's.
Even when i truncate and retry the same thing occurs.
What could be the reason for the same??

We have a large table which is very old and not much ppl take care about, recently there is a performance problem from the report need to query to this table. Eventally we find that this table have primary key missing and there is duplicate data which make "alter table add primary key" don't work
Besides the data size of this table require unacceptable time to execute something like "insert into new_table_with_pk from select distinct * from old table"
Do you have any recommendation of fixing this? As the application run on oracle , sybase and sql server, is that cross database approace will work?

When I tried to create a bar chart using SSRS 2012, the vertical axis values are repeating for smaller data sets values. It's only happening when the data labels are below 5, when the data is above 5 this chart represents data fine.
I tried specifying the custom intervals and this option all together eliminated the  bar for value 1, instead it only showed the value 1 as text on the chart.
I tried changing the data interval type as number and the data type is of Integer, these are counts which I am showing in the chart.

Situation:
2 servers: 1 production, 1 test.
While my application is running on the production server, I want to develop on the test server. After a few weeks, I want to update the application, and have to update the database structure on the production server also with the most recent one from the testserver, but without deleting the current data on the production server.
I create/modify all tables in SQL Server 2005 via Management Studio. The application is built in VS2008 Pro. I'm using SubVersion (SVN).
I can let Management Studio generate scripts for every change and store them manualy, but that's a little bit too much work. What I want is a sort off version control solution. A solution that a service running on the background tracks every change on a specific database on my test server, and stores them as T-SQL code in a repository. Then I can collect all those T-SQL scripts, and run them against the production server.
Is there some solution for that?

I want to create a page(using GridView) where it will detect changes made in the database and display it for Administrator observation. I've created a table name history for this purpose.
History
guid (uniqueidentifier)
dateCreated(datetime)
lastDateUpdated(datetime)
changesMade(varchar(50)) ---- eg; dropdownlist
oldValue(varchar(50)) ----- compaq
newValue(varchar(50)) -----dell
updateBy(varchar(10)) <------ username of registered user
comNo(int) = foreign key for Computer table
History data will insert data whenever a changes made. Could anyone advise and direct me how to do this function. I was thinking of using stored procedure to insert the data. Thanks in advance.

I have an application that has a SQL back end, and I want to be able to track who is accessing a record so that no one else can access it at the same time. I was going to do this with a table or application state, but how can I avoid keeping files locked when someone abandons a session? Any Ideas?

Hi
We need to keep track of all changes that are made to our tables.
The changes will be saved in a table that records:
- the table in which the change was made
- the name of the field that was changed
- the old data for the field
- the new data for the field etc..
I've seen a few examples that record the name of the table that was
modified but none that record done to the field level.
Can anybody give some guidance?
Thanks..

I need to be able to track which users and the number of times a user connects to a particular SQL Server database. I have a simple SQL Server database that users query (SELECT only) using an Access 2000 front-end. I do not have any control over the front-end so my only tools on the database side. I can't use 3rd party software, just SQL Server. Is there any way? Thanks.

I have a requirement. I am having a database which is having views,procedures and tables. Many users are having access to the database. If i want to track all the schema changes happening in the database how to achieve that? As in i have used some tables in a procedure and someone might change the column or drop the column. So it is going to have impacts on my procedure. I need a trigger which tracks all the changes done in a database and the impacts those changes are going to make.

In my Sql Server 2012 I have the following table in a database
CREATE TABLE [dbo].[HumanResource](
[ID] [int] IDENTITY(1,1) NOT NULL,
[Name] [nvarchar](50) NOT NULL,
[IsHired] [bit] NULL,
[Address] [nvarchar](max) NULL,
[Score] [bigint] NULL,
[Code] ....
Considering that sql server Update is a chained Delete and Insert, the first row is the delete row capture and the second one is the insert row capture.
But I don't understand why the address is tracked as NULL when I update other fields.

I have a strong feeling that this isn't possible but I thought I might as well ask...
I'm developing a database application (SQL Server 2000 backend) where the client and the server is separated over a slow network connection (satellite). There are parts in the application where I will have to query a large resultset so I was wondering if there is a way to determine the percent complete of a query so I can put a progress bar on the interface so the user can see it loading data instead of having a frozen form.
I thought about spliting up the query into different ones and update the bar once each separate one is complete but I'd rather not do that because in the application development environment I'm working in, I have to close the resultset and reopen it every time I do a query... unless this isn't a big deal but I'm under the impression its something to avoid.
Thanks!

different Users are running select statements under their own login. they have readonly permission to the database. My goal is to track all those queries and send notification which tables were opened and which columns were displayed...Looks like I need trigger on select statement for the table...( Unfortunetely it doesn't exists)
I collect all those statements in trace file and in the night time I stop trace, move file data to table and then step by step try to massage sql queries using VB.net... Most of those queries are so complicated, have derived tables inside and it is really hard to parse these sql statements...
1.If anybody has an idea how to say: User B opened table tbl_A col_B twice per today...using different methodology rather then go through SQL.(Other words how to create an event on a table which will be fired in a case of request select any column of that table?)
2.If somebody know where we can take good parser which will help with this job?
Thanks

I am an advanced user of MS Access and other databases but relatively new to SQL Server. I am utilizing SQL Server Express to analyze a database that was created by another entity. I am interested in looking at any specific record in any table and seeing who created that record, what date/time the record was created, who edited the record, when that edit occurred, etc. I don't see any such fields in the database. Would the designer of the database have to have explicitly added such functionality, or is this information available but just hidden from the novice's view?
Thanks for your help.
