Inner Join Duplicate Data
Jun 13, 2000
i have 2 tables not connected in any way
but both have orderid filed (same filed).
In one table this filed (and onther one) are keys,
the second table dose not hace a key at all.
The same order_id CAN repeat itself in each table.
When i try to join the tables (some rows just in one table and some in both):
Select tab1.name, tab1.orderid, tab2.sku
from tab1 inner join tab2 on tab1.orderid=tab2.orderid
The result i get is duplicate.
each row is multiple.
What I'm doing wrong?

select a.[Cuno], [doc_type], [Doc_name]
from [assembly] a
left join [assembly_Doc] doc
ON a.id = doc.assembly_id
left join [assembly_Recog] re
ON a.id = re.assembly_id
where [activate] =1
and doc.doc_type = 1
I only have two records for doc_type =1 in the [assembly_Doc] table. Without joining the third table [assembly_Recog], the results is corrected, 2 records returned. I need to join with [assembly_Recog] table, but when it joined, I got the duplicate records. It listed twice. pls see the results below:
CusNoDocType DocName
CUS-022 1B1489-01 Rev 1
CUS-022 1B1489-01 Rev 1
CUS-022 1B149-02 Rev 2

I had a problem before of not been able to find the rows with 0 values. I've now managed this although it's brought up duplicate rows due to the discounts been different on the same Mfr_part_number. I tried using the max function on the isnull (Exhibit_Discount.Discount, 0.00) AS Discount instead but to no success. i think i maybe something to do with PK keys not been used in the set-up of the database.
Use Sales_Builder
Go
SELECT DISTINCT
GBPriceList.[Mfr_Part_Num],
[Code]....

Hi,
I'm having a little trouble with the following code:
SELECT DISTINCT cd1.*, cd2.*
FROM Table1 cd1 LEFT JOIN Table2 cd2
ON cd1.RegNr=cd2.RegNr
WHERE cd1.RegNr = $RegNr
I want it to return the 2 rows that is present in the tables but it returns 4.

My SQL statement is: SELECT Table.Name, Table2.Country FROM Table Left Join Table1 ON Table.Rowid = Table1.Rowid Left Join Table2 ON Table1.Rowid1 = Table2.Rowid1
My final result is shown on Table2. But is it possible if I can generate the results without the duplicate Names (as shown below)?
Name

Any advice will much appreciated.

I am using SLQ Server 2008 R2. The database was designed by another company.
I have two tables: Client and Client_Location. In the Client table the pk is Client_ID. There is also a unique key: sys_Client_ID. Both the Client_ID and the sys_Client_ID fields exist as a foreign keys in the Client_Location table. However, the fields are not noted as unique in the Client_Location table. There are two fields in the Client_Location table that determine when the address was effective. They are from_dt and end_dt.
Multiple records have been loaded into the Client_Location table to track old as well as current addresses of clients.
I'm trying to run a report that will pull clients with a plan_id constraint from the Client table and join the Client_Location table to retrieve the current address of these clients.
My SQL is:
select distinct (a.client_id), a.cli_last AS Last_Name,
a.cli_first AS First_Name, a.cli_middle AS Mid_Init,
b.city AS City, b.county AS County, b.state AS State
from ECBH.dbo.tbl_Client a inner join ECBH.dbo.tbl_Client_Location b
on a.client_id = b.client_id
inner join ECBH.dbo.tbl_client_insurance c
on a.client_id = c.client_id
inner join ECBH_TEST.dbo.tbl_GEF_County d
on b.county = d.COUNTY_NAME
where c.plan_id = 4
order by a.cli_last, a.cli_first
Because multiple records exist in the Client_Location table, the result set has duplicates. How can I pull only the results where the from_dt is most recent?

I have 4 tables (SqlServer2000/2005). In the select query, I have FULL JOINED all the four tables A,B,C,D as I want all the data. The result is as sorted by DDATE desc:-
AID BID BNAME DDATE DAUTHOR
1 1 abcxyz 2008-01-20 23:42:21.610 c@d.com
1 1 abcxyz 2008-01-20 23:41:52.970 a@b.com
1 2 xyzabc 2008-01-21 00:17:14.360 c@d.com
1 2 xyzabc 2008-01-20 23:43:17.110 a@b.com
1 2 xyzabc 2008-01-20 23:42:43.937 a@b.com
1 2 xyzabc NULL NULL
2 3 pqrlmn NULL NULL
2 4 cdefgh NULL NULL
Now, I want unique rows from the above result set like :-
AID BID BNAME DDATE DAUTHOR
1 1 abcxyz 2008-01-20 23:42:21.610 c@d.com
1 2 xyzabc 2008-01-21 00:17:14.360 c@d.com
2 3 pqrlmn NULL NULL
2 4 cdefgh NULL NULL
I want to remove the duplicate rows and show only the unique rows but contains all the data from the first table A. I have to bind this result set to a nested GridView.

Hello,
This probably has been addressed before but I was unable to get the search to work properly on this site.
I am needing a script/way of deleting all rows from a DB with the exception of one record left for each row that has duplicate column data. Example :
Row 1
Field1 = 12345 Field2 =xxxxx Field 3=yyyyy Field4=zzzzz etc.
Row 2
Field1 = 12345 Field2 =zzzzzz Field 3=xxxxxx Field4=yyyyyy etc.
Row3
Field1 = 12345 Field2 =20202 Field 3=11111 Field4=zzzzz etc.
Row 4
Field1 = 54321 Field2 =xxxxx Field 3=yyyyy Field4=zzzzz etc.
Etc. Etc.
I want to be able to find the duplicates for Field1 and then delete all but 1 of those rows.( I don't care which one I keep just so only one is left.) The data in the other fields may or may not be unique.
I know how to find the duplicates it's just the deleting part I am having problems with. Any help would be much appreciated. Thanks,
Kerry

I am new to SQL server 6.5.
I will need to stress test a sql server 6.5 test database by duplicating
data. To do so, I need to know how to modify the primary key(which are
numbers in character data type) to duplicate the data several times over.
The primary key is character data.
What I have done ion the past is use insert statments -let's say 20 -- and then copy them and change the date in a text editor and change the primary key column and the other coluimns with thea replace of different letters and numbers. This is slow and tedious.
Does any one have a script I can run to do so?
Can I do this sql or do I need some sort of stored procedure? Any help
would be appreciated. Thanks.

would be greatly appreciated. THanks.

Hello all,
I have recently been working on a project that requires one simple table to insert data into. The problem here is that all the data inserted must only access the database via stored procedure and I want to ensure that no duplicate data is inserted in the database.
I have done quite a bit of research for many ways to perform duplicate data testing from building temp tables and on, but nothing has really stood out to me yet. I would really like to find some information on how to perform duplicate data testing using a stored procedure that allows to test the data being inserted before it is saved to the database; therefore, when the user inserts the fields and clicks the insert button, the fields will be tested against the existing data (via stored procedure) within the database before being added.
Can anyone help?
Thanks

Hello people, not sure how to do this. I have a unique Claim ID and when joined with the code table has 4 different Code ID and the Claim Amt is also unique to the Claim ID (One Claim Amnt per one Claim ID). I need all of these data for the report my problem is in getting the correct summation of the claim amt since this looks like I have 4 amounts of $1773.31 when in actuality there is only one. The Code ID is also part of the report parameter so I tried assigining the $ amount to just one of the Code ID but that will not work incase that particular Code ID is not selected in the parameter, the claim would read as a zero. Any help would be appreciated. Thanks
Claim ID: Code ID Claim Amt

Hi everybody,
I'm migrating a table that has above 20,000 records and lot of duplication.Let's say an Employee table with multiple records having slight
diference in the EmployeeName field.Now nobody would like to sit and manually identify them with such hugh number of records.
Is there any way which would help me identify most of them and
reduce the redundancy.
Thanx

I have a query that for one reason or another produces duplicate information in the result set. I have tried using DISTINCT and GROUP BY to remove the duplicates but because of the nature of the data I cannot get this to work, here is an example fo the data I am working with
ID Name Add1 Add2
1 Matt 16 Nowhere St Glasgow
1 Matt 16 Nowhere St Glasgow, Scotland
2 Jim 23 Blue St G65 TX
3 Bill 45 Red St
3 Bill 45 red St London
The problem is that a user can have one or more addresses!! I would like to be able to remove the duplicates by keeping the first duplicate ID that appears and getting rid of the second one. Any ideas?
Cheers

Hi. Not sure which section this request needs to be put in, but i'm relatively new to SQL.
I have 1 table which contains an user_id (autonumber), user_name, and user_profile.
I have 2 other tables:
config_version (cv) and config (c)
These two tables both access the user table (us) to view the user_id (which is required).
I want to be able to view the user_names for both "cv" and "c" on a seperate page. Using the code below, i'm lost. I created what i wanted in MS Access with the use of a 2nd table (this might be easier to understand than my rant above). However, I don't want a 2nd table.
Can someone provide me with a function, or the "answer" to my problem?
Highlighted Blue - just there to fill in the front page with data (not wanted)
Highlighted Green - doesn't work, but was my first attempt
Code:
public function ShowQuotes
Dim objConn
Dim objADORS
Dim strSQL
Dim row
Set objConn = Server.CreateObject("ADODB.Connection")
objConn.ConnectionString = strConn
objConn.Open
Set objADORS = CreateObject("ADODB.RecordSet")
strSQL = "Select top 50 "
strSQL = strSQL & " cv.config_version_id as cvid, cv.configuration_id as cid, cv.version_number as cnum"
strSQL = strSQL & ", cv.status as cstat, cv.total_price as cprice, cv.modification_date as cmod, cv.version_description as cvrem"
strSQL = strSQL & ", c.remarks as qrem"
strSQL = strSQL & ", p.prod_description as pdesc, p.version as pvers, p.status as pstat"
strSQL = strSQL & ", cust.customer_name as custname"
strSQL = strSQL & ", us.user_nt_login as modname"
strSQL = strSQL & ", us.user_name as usname"
' strSQL = strSQL & ", cv.user_id as modname"
strSQL = strSQL & " from tbl_config_version as cv, tbl_configuration as c, tbl_product as p, tbl_user as us, tbl_customer as cust"
strSQL = strSQL & strWhere 'SETS RESULTS TO BE UNIQUE
strSQL = strSQL & " and us.user_id = c.user_id"
strSQL = strSQL & " and cv.configuration_id = c.configuration_id"
strSQL = strSQL & " and c.product_id = p.product_id"
strSQL = strSQL & " and c.customer_id = cust.customer_id"
strSQL = strSQL & strOrderBy & ";"

This is probably a silly question to most of you, but I'm in the processof splitting off years from a large DB to several smaller ones. Some ofthe existing smaller DBs already have most of the data for theirrespective years. But some of the same data is also on the source DB.If I simply do an insert keying on the year column, and a row beinginserted from the source DB already exists in the target DB, will aduplicate row be created?And if so, how can I avoid that?Thanks,John Steen*** Sent via Developersdex http://www.developersdex.com ***Don't just participate in USENET...get rewarded for it!

Hello,
I have a dataset which I would like to remove data from, but I can't seem to find out how to do this.
The dataset contains the following columns:
SCode, NIn, SIn, AIn, NOut, SOut, AOut and TagNumber.
I would like to remove data from the dataset when the following occurs:
("SC123", "NIn123", "s-in-323", "a-in-342", "NOut43", "s-out-231", "a-out-45", "tagnumber12")
("SC123", "NIn123", "s-in-xyz", "a-in-xws", NULL, NULL, NULL, "tagnumber12")
This is when NIn occurs with the same value more than once, and I would like to remove (or ignore, filter) the row when NOut, SOut and AOut are null.
I am new to SSIS and can't see how I could do this (although I'm sure it's possible).
If anyone could show me how I would appreciate it.
Thanks.

Hello Everyone:
I am using the Import/Export wizard to import data from an ODBC data source. This can only be done from a query to specify the data to transfer.
When I try to create the tables, for the query, I am getting the following error:
Msg 2714, Level 16, State 4, Line 12
There is already an object named 'UserID' in the database.
Msg 1750, Level 16, State 0, Line 12
Could not create constraint. See previous errors.
I have duplicated this error with the following script:
USE [testing]
IF OBJECT_ID ('[testing].[dbo].[users1]', 'U') IS NOT NULL
DROP TABLE [testing].[dbo].[users1]
CREATE TABLE [testing].[dbo].[users1] (
[UserID] bigint NOT NULL,
[Name] nvarchar(25) NULL,
CONSTRAINT [UserID] PRIMARY KEY (UserID)
)
IF OBJECT_ID ('[testing].[dbo].[users2]', 'U') IS NOT NULL
DROP TABLE [testing].[dbo].[users2]
CREATE TABLE [testing].[dbo].[users2] (
[UserID] bigint NOT NULL,
[Name] nvarchar(25) NULL,
CONSTRAINT [UserID] PRIMARY KEY (UserID)
)
IF OBJECT_ID ('[testing].[dbo].[users3]', 'U') IS NOT NULL
DROP TABLE [testing].[dbo].[users3]
CREATE TABLE [testing].[dbo].[users3] (
[UserID] bigint NOT NULL,
[Name] nvarchar(25) NULL,
CONSTRAINT [UserID] PRIMARY KEY (UserID)
)
I have searched the "2714 duplicate error msg," but have found references to duplicate table names, rather than multiple field names or column name duplicate errors, within a database.
I think that the schema is only allowing a single UserID primary key.
How do I fix this?
TIA

I have a table storing only 2 FKs, let's say PID, MID
Is there any way that I can check distinct data before row is added to this table?
For example, current data is
PID MID------------100 2001100 2005101 3002102 1009102 7523102 2449
If my query is about to insert PID 100, MID 2001, since it's existing data, i don't want to add it. Can I use trigger to solve this issue?

I want to import data from a live site database into a development database (SQL Server 2005 Express) using the DTSWizard. Once I copy/paste the live database to my dev machine, I cant attach the live site database because it has the same name as the database on the dev site.A simple solution I would assume is to change one of the names. But I can't seem to change the "orignal file name". A backup/restore won't work for me because I made table/field changes to the dev database. Thanks --Dietrich

I'm working on a web app that needs to be able to take a row in the database and duplicate it, creating a new row in the same table with the same data except for the ID field and reference field.So basically: table1.row1 references table2.row1. I need to duplicate the data in table1.row1 (creating table1.row2) with the same reference to table2.row1.Is there any easy way to do this in SQL? I'm just looking for some ideas or a framework to accomplish this.

Hi, I am new to SQL 7.0 and I have a large database but with some duplicate
problems.
For example, in a table tblA we have columns as:
userid, lname, fname, street, state... etc,
The problem is: The same user sometimes use different styles for his/her street and state (suppose he/she always use same userid, lname and fname),
such as,
street State
7531 Plum Drive Maryland
7531 Plum Dr. MD
So a same user can produce a lot of duplicate user infomation. Can anybody
help to elimenate this kind of duplicate data?
Thanks.

I just converted an old non-relational database into something that MS SQL likes. The old primary keys were broken up into two columns, one being useful. The column I need to use has some rows with the same values in them.
I am looking for some way in a SQL script to look for the duplicate rows and add "_X" to the data where X is a value incremented by 1 for each duplicate row found.
For example, 3 duplicate rows with "5443aa" would return "5443aa", "5443aa_1","5443aa_2".
Any ideas?

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.
