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”

Hi,
As far as I know in SQL Server 6.5 there is no concept called rowid. How can I find duplicate records in a table and delete them.
Thanks,

I have this query that I have been using to find duplicate records works great except for now. The logic I am adding is pcs_rreas <> 'NG'. When I add this it does take out the NG, but it also excludes the reocords that have NULL data in this field. I don't want that to happen. How can I fix this? I tried adding (pcs_rreas <> 'NG' or pcs_rreas is null) but nothing is pulling now.
SELECT pcs_id1, pcs_rreas, pcs_lname, pcs_fname, pcs_minit, pcs_degree, pcs_xtyp, pcs_office, pcs_dba, pcs_dob, pcs_sex, pcs_eff, pcs_trm, pcs_spec1, pcs_spec2, pcs_spec3,
pcs_spec4, pcs_tax1, pcs_ssn, pcs_altid, pcs_upin, pcs_medic, pcs_mcaid, pcs_ecs, pcs_npi, pcs_status, pcs_dir, pcs_den, pcs_www, pcs_hold, pcs_email,
pcs_misc1, pcs_misc2, pcs_newdt, pcs_newby, pcs_chgdt, pcs_chgby, pcs_malp, pcs_pf, pcs_ctl, pcs_sys, pcs_pay, pcs_ann, pcs_bcert, pcs_pass, pcs_w9,
pcs_taxex, pcs_tax2, pcs_type, pcs_rreas, pcs_routo, pcs_rtime, pcs_rdate, pcs_force, pcs_flag, pcs_v419, pcs_bcity, pcs_bstate,

I'm using this to find duplicates where a person has the same email but varying firstname and lastnames:
select distinct t1.booking_id, t1.first_name, t1.last_name, t1.email_add, t1.booking_status_id
from [aren1002].[BOOKING]
as t1 inner join [aren1002].[BOOKING]
as t2
on t1.last_name=t2.last_name and t1.booking_id<>t2.booking_id
where t1.booking_status_id = 330
order by last_name asc
Sample data:
3927 Greg Smith greg@emailno1.com 303
5012 John Smith greg@emailno1.com 303
6233 John Smith greg@emailno1.com 303
4880 Dulcie Abuud dulcie@theiremail.com 303
However it is listing the non duplicate rows, For example: The record with Abuud as the last name, doesn't have any duplicates in the table, so I don't want it listed.
The data should be like this:
3927 Greg Smith greg@emailno1.com 303
5012 John Smith greg@emailno1.com 303
6233 John Smith greg@emailno1.com 303

Hello,
Not sure how to do this. I think I need to use a Group By query. I have a "Products" table with the following fields:
Program#
Number
UPC
Item
Item#
Size
Dept
Everything is specific to the Program#. In other words, for every instance of a Program# there can be more than one Product, which is specified by the "Number" field. So: SELECT * FROM Product WHERE [Program#] = '12345' should return this:
12345 | 1 | 000012345678 | Cookies | 98765 | 12ct | Retail |
12345 | 2 | 000012345678 | Cake | 98765 | 12ct | Retail |
12345 | 3 | 000012345678 | Ice Cream | 98765 | 12ct | Retail |
However, some recordsets are returning like this:
12345 | 1 | 000012345678 | Cookies | 98765 | 12ct | Retail
12345 | 1 | 000012345678 | Cake | 98765 | 12ct | Retail
12345 | 2 | 000012345678 | Ice Cream | 98765 | 12ct | Retail
In which case I have to fix them (the "Number" field) with an update query sp they are numbered sequentially. Luckily, this doesn't happen very often.
Can someone help me with a query that will return only those records with duplicate values in the "Number" field? I am not sure how to construct this query which I will use as a stored procedure.
TIA,

I need to run a query to discover all instances where a f_name and f_country pair exists for more than one f_ID. ABC/US is one such example; IDs 123 and 456 have this pair.

In the FLAT FILE source, I have to find the duplicate rows based on the two fields say, "bill number" & "invoice date".
The rows within flat file has like "bill number" which is duplicated on the same "invoice date".
If duplicate rows found then move the duplicate rows into another Flat File.
If not found then move the rows into Sql Server Table.
Pls provide the solution. Thank you

Someone ran an update statement multiple times so their are multiple entries in the table. Â What is the quickest way to track down the multiple entries? Â I would only want to see where timein and timeoff exist in the table multiple times for the same id. Â So this would be a duplicate
EntryID -- ID Â -- timein -- timeoff
1487 Â 11 Â Â 2015-05-05 16:33:23 Â 2015-05-05 18:45:26

I have a table which is a license holder table (i.e., plumbers, electricians etc...) There are some people who appear in the table more than once as they have more than 1 type of license. I am tasked with querying out 200 of these people a week for mailing a recruitment letter which I am doing using the following select statement:
SELECT TOP 200 Technicians.Name, Technicians.Address, Technicians.City, Technicians.State, Technicians.ZipCode, Technicians.LicenseType
FROM Technicians
My problem is that this doesn't deal with the duplicates and distinct won't work because I need to pass the license type and that's the one field that's always distinct while the name and adress fields duplicate.

I'm ok at SQL, but this has really confused me - please help!
I've got a table which (amongst others) has two columns - myID, and barcode. Ideally myID and barcode should be a 1 to 1 relationship... but it's not. So how can I get a list of all rows where 1 barcode value has >1 myID? (and also vice versa if possible). Thanks!

Hi Guys!
I am trying to figure out a query to which the logic is simple, but I'm missing some basic SQL skill or technique somewhere.....
I have a table called NAME, from which I want to display the following columns:
namecode name Postaladdress
(there's a column called NAME as well as the table being called name incase your wondering)...
I'm concerned with the namecode and name columns for now....
I want to find duplicate name values from the table, how do I do this?
for example, in name, I have the value 'Long water Beach' appear twice. I want the query to show me how many times this appears from this table (duplicate values??)
Both namecode and name are navchar datatypes. So far I tried something like:
select name, namecode, postaladdress
from name
where name in
(select name
from name
group by name, namecode, postaladdress
having count(name) > 1)
I guess we can focus on the subquery here, but I just need that function or code which shows me the duplicate values!! I know its something staring me in the face, but I just can't see it!!
Any help please???
Much appreciated

We are experiencing a problem at more than one site - it has only
just started happening.
We are actually getting duplicate Identity column values in various
tables and the values seem random - its not like the counter just gets
wound back.
We have used dbcc checkident and also bcp out and in the data, which
of course corrected the tables but only temporarily. Our application
is not doing any select into`s - just plain old inserts which for some
reason are allowing dups to be inserted into the tables.
problem sites are either sp3 or sp4.
There are thousands of sites (including most of ours) where there are
no problems like this with this particular app.
Any help from anyone would be most appreciated.

I know this question has been asked before but this is a little different and I can't seem to get my head around it right now.
What i have is a table like so:
ID1 ID2 DESC
100 24 something1
100 24 this is a test
100 24
100 25 somethingelse
101 36 something
101 37 something else altogether
What i need is to determine which ID1 value has the same ID2 value listed more than once WITH the description filled in. If there is no description filled in even though the ID2 may be listed twice on one ID1, then it's ok and don't want it displayed in the query.
So, in this case, ID1 of 100 has ID2 24 listed twice with a description on both ID2's (of 24). this is what I need to show up in the query like so:
ID1 ID2 DESC
100 24 something1
100 24 this is a test
Could someone give me a hand with this? I've found similiar problems...but haven't been able to apply those answers to this.
Thx

HI, I keep getting this warning with a lookup (full cache mode) that retreives data form a table that contains the following information:
SRCE_SYS TABLE_NAME FIELD_NAME CODE ENGLISH_DESCRIPTION
STATIC STATIC PM_PC_TX_TYPE_CODE G GROSS
STATIC STATIC PM_PC_TX_TYPE_CODE E EXCESS
STATIC STATIC PM_PC_TX_TYPE_CODE F FACULTATIVE
STATIC STATIC PM_PC_TX_TYPE_CODE S SURPLUS
STATIC STATIC PM_PC_TX_RIDER_CODE BOAT BOAT
STATIC STATIC PM_PC_TX_RIDER_CODE RIDER RIDER
STATIC STATIC PM_PC_TX_RIDER_CODE CONT CONTENTS
The column tab matches SRCR_SYS, TABLE_NAME and FIELD_NAME (using constants defined in a derived column transform) .The code column comes from the source. We want to retreive the english_description colum from SRCR_SYS, TABLE_NAME,FIELD_NAME and CODE in the dataflow.
I would normally ignore the warning but sometimes, it seems that the lookup does not match any values and enabling memory restriction on the advanced tab resolve the issue and suppress the warning.
As I said, I keep getting this warning and I don't know why since there are no duplicates in the table? Am I missing something?
Thank you,
Christian

Is there a setting in SQL Server that ensures a column is not allowed to have the same value more than once? Or must this be set up in the insert statment itself? Or how about a business rule?
