Hi All.
I have a Table with records and some of them are actually multiple records. I need to query SQL 2005 (compare) field values on more than one column to return these records.
I am an absolute beginner and need some guidance on how to start on this. Can anyone advise.
Thanks.

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.
DROP TABLE [dbo].[TestBusiness];
GO
CREATE TABLE [dbo].[TestBusiness](
[Business_pk] INT IDENTITY(1,1) NOT NULL,
[BusinessName] VARCHAR (200) NOT NULL,
[Address] VARCHAR(MAX) NOT NULL,
[code]....
Hi
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.
Hope you can help.
Thanks
mytable fld1 int primkey fld2 varchar(20), fld3 varchar(20)From the definition of the above table, how do i do i modify my below query to only select the rows with duplicates in fld2. I know a groupby with a having count will display the duplicates for a given field, but i want my query to see all the fields and rows that are duplicates. select fld1, fld2, fld3 from mytable

Hello everyone,
Obviously, I'm new here so I'd like to start by thanking anyone for their help with this very newbie SQL search query question.
I have been tasked with trying to figure out how to get search results from several different columns of two different tables within a database. I have successfully accomplished this, but one column has many many duplicates. I have read on these forums about using the DISTINCT command to eliminate this, but so far have been unsuccessful. Here is the search I'm using...(columns 1, 2, and 3 are from one table and columns 4 and 5 are from another. The results need to be in ascending order (alphabetical) of column1.
select column1, column2, column3, column4, column5 from table1, table2 order by column1;
The result of this is great except that column1 has many duplicates.
I tried entering the search like this...
select distinct column1, column2, column3, column4, column5 from table1, table2 order by column1;
...but that didn't seem to help.
Can someone steer me in the right direction?
Thanks for any and all assistance.
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?

the query above is basically.. selecting all the fields from a table in database W/OUT their primary key. then putting them in a temp table.. delete all the records in the original table. then paste the records from the temp table into the original table.
is there a way for this to work? i don't know how to use the variables w/ this script. please help me correcting this query..
this is for removing duplicates btw. thanks!
join three tables and wont be duplicate records.
I have tried and attached the computed results and also expecting results.
IF OBJECT_ID('tempdb..#tmpExam1')IS NOT NULL DROP TABLE #tmpExam1
IF OBJECT_ID('tempdb..#tmpExam2')IS NOT NULL DROP TABLE #tmpExam2
IF OBJECT_ID('tempdb..#tmpExam3')IS NOT NULL DROP TABLE #tmpExam3

I am working with a bunch of records that have duplicates on the Persid and the intPercentID where there are duplicates I want to remove when I stick them in the temp table, I tried join on tempo table and doing not exists but still inserts, so now I am trying a merge but same thing. how can I keep duplicates from being inserted in the temp table. I made a cursor as well but its slow as heck, but it does work. trying better ways.
Create table #TempStr (STRId int not null Identity(1,1) primary key, Persid int, percentId int, dtCreated datetime, CreatedBy int)
Create table #NewStr (STRId int, Persid int, percentId int, dtCreated datetime, CreatedBy int)

that's what I have, and I need to find all instances where parent_key=child_key.
I've been trying something similiar to...
[SELECT name, count(name), name2, count(name2)
FROM people
GROUP BY name, name2
HAVING (count(name)>1 AND count(name2)>1)]
The problem is that I keep getting error messages because I can't use

I was hoping you guys might have a suggestion for me. Thanks ahead of time.
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"...

I'm joining several tables and when I add the last one I get duplicate results. How can I get just one for each?
select a.field, b.field, c.field

left outer join ctblname as c on a.id = c.parent_id
There are more than one result when joining tbl a and c, but I'm getting a reult for each of them for all results from joining a and b.
Is there a query or a way to convert duplicates value in a column to non duplicates.

I have created a database that looks like the following:
FirstName Table link to Main Table.
I have created a Stored procedure that looks like this:
Create procedure dbo.StoredProcedure
(
@FirstName varchar(20)
)
Declare FirstNameID int
Insert Into Main Table
(
FirstName
)
Values
(
@FirstName
)
Select @FirstNameID = Scope_Identity()
How could I redesign this to check if a value exists and if it exists then simply use that value instead of creating a new duplicate value?
Thanks!!
I have a dilema..... I have a databas eof about 60,000 users and i need to get rid of those users where there is a duplicate email address. I have written an asp utilty that works but is far too taxing on our little server and i thinkk itwill kill it. what it does is for each email address it compares it against all the others.... so for each address it checks against 60,000 other records 60,000 times.... you know what i mean. its pretty phucked.... i tested it on just one record and took about 5mins.
anyway ive been trying to do it in SQL with no luck
here is a simplified version of my dilema

NAMEEMAILAGE

marycool@mail89
thomas tom@mail13
richrich@mail65

so what i want to do is cut it down so there are no duplicate email addresses. I want the table looking like this:

Can you think of a way to do this?
i tried the following but it gets rid of duplicates of other fields which is not what i want to do
CREATE table distinct_records
SELECT name, Email, Age
FROM duplicate_records
GROUP BY name, Email, Age;
any ideas guys?

the schema is
directoryid firstname, lastname, extension
703168 Andrew Lim 78094
703154 Joseph Egan 78888
704548 Andrew Lim 78094
I realized the spreadsheet had a large number of duplicates. How can i delete the duplicates ?
like deleting directoryid 703168 only.
i'm trying to get duplicates out of the my database
SELECT COUNT(*) AS Amount,
Firstname,
surname,
Internalextension

How do i alter the query just retrieve records which have firstname and lastname which are similar but different extension numbers ?
Hi,
This is the query which shows me the duplicates
Some of the records have more than one records
I would like to know how to delete the extra records so that I will end up with one record per row.
select

VaR_Identifier,
Price_Date,
PX_Last,
Count(*) as 'count'
from
tblPricesClean
group by

order by

Hi,
Is there a way to find duplicates in one field? For example my query has person_nbr and for each person_nbr on one day they could have used multiple payer_names. I want to be able to count each person_nbr one time but also I want to group by description(which is the name of the provider) and by payer name to see how many person's that the provider seen with each payer. My problem is that if the person had more than one payer they are counted twice. Is there some type of aggregate function to use the first payer in the list??
With PersonMIA (person_id,person_nbr,first_name,last_name,date_of_birth) as
(
select distinct person_id,person_nbr,first_name,last_name,date_of_birth from
(select count(*) as countenc,a.person_id,a.person_nbr,
a.first_name,a.last_name,
a.date_of_birth
from person a
join patient_encounter b on a.person_id = b.person_id
group by a.person_id,a.person_nbr,a.first_name,a.last_name,a.date_of_birth )tmp
where tmp.countenc <=1
)
select person_nbr,payer_name,first_name,last_name,description,year(create_timestamp),create_timestamp
from
(
select distinct c.description,tmp.person_id,tmp.person_nbr,tmp.first_name,
tmp.last_name,tmp.date_of_birth,d.payer_name,b.create_timestamp
from PersonMIA tmp
join person a on a.person_id = tmp.person_id
join patient_encounter b on a.person_id = b.person_id
join provider_mstr c on b.rendering_provider_id = c.provider_id
join person_payer d on tmp.person_id = d.person_id
where c.description = 'Leon MD, Enrique'
group by c.description,tmp.person_id,tmp.person_nbr,tmp.first_name,tmp.last_name,
tmp.date_of_birth,d.payer_name,b.create_timestamp
)tmp2
where year(create_timestamp) IN (2005,2006)
group by person_nbr,payer_name,first_name,last_name,description,create_timestamp
Thanks in Advance!

Hi,
I'll see if I can explain this clearly. The query below
selects rows from the "hdr_ctl_nbr_status" table if the value in the field "tcn" from that table is found in the table "temp_tcn". I want all fields from the "hdr_ctl_nbr_status" table to be selected BUT only one row. In other words for a tcn with a value "12345678" there are 10 rows returned from the hdr_ctl_nbr_status table, I want only 1. Is there a way I can use SELECT DISTINCT to do this ? I know this usually functions on one or more fields but I want the DISTINCT to be on tcn only BUT return all fields in the query.
Select h.*,'' from hdr_ctl_nbr_status as h WITH (NOLOCK)
where h.tcn in (select tcn from temp_tcn)
Thanks, sorry if this is too confusing. Jeff
Hi, All,
I have two columns of int data in the a table, as my example data shows below.
I want my data returned to be something like those in #test3, but my question is this, how can I do it without using #test2 and #test3?
By the way, the business requirement doesn't care it's min/max or any ID when one side has duplicated values.
Thanks!
Use tempdb
Go
if object_ID ('#test') is not null drop table #test
create table #test (col1 int, col2 int)
insert into #test
Select 123, 222 union
Select 124, 222 union
Select 125, 222 union
Select 111, 223 union
Select 111, 224
if object_ID ('#test2') is not null drop table #test2
create table #test2 (col1 int, col2 int)
Insert into #test2
Select distinct col1, min(col2) from #test group by col1
if object_ID ('#test3') is not null drop table #test3
create table #test3 (col1 int, col2 int)
Insert into #test3
Select min(col1), col2 from #test2 group by col2
Select * from #test3
I am attempting to execute the Stored Procedure at the foot of thismessage. The Stored Procedure runs correctly about 1550 times, butreceive the following error three times:Server: Msg 512, Level 16, State 1, Procedure BackFillNetworkHours,Line 68Subquery returned more than 1 value. This is not permitted when thesubquery follows =, !=, <, <= , >, >= or when the subquery is used asan expression.I've done some digging, and the error message is moderatelyself-explanatory.The problem is that there is no Line 68 in the Stored Procedure.

Hello!
Just looking for advise on dealing with duplicates in database.
I have a contact table that have a bunch of duplicated customer records.
My goal is to combine all duplicated records into one record.
This involves couple tables:contact,contact history ,calendar.
All tables related by common column "accountno".
What would be the best approach for this?
Thank you,

The resultant is all the original rows also getting deleted with the duplicates..anyone please help me out..

I have a customer database with the following structure:
Dept ID (int)
Section (varchar)
I need to find only occurrences of a section (eg Admin) where the section name has a record in Dept 1,2 and 3 - only return the result if the record for Admin is associated will these depts.
Example Data:
Dept Section
1 Admin
1 Finance
1 Marketing
2 Admin
2 Sales
2 Marketing
3 Admin
3 Sales
3 Finance
The query would only return 'Admin' since this is the only Section that is represented in Departments 1,2 + 3.
I am not in control of the data design and can't create a bitwise field to achieve this.
