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”
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.
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 1623 Â 11 Â Â 2015-05-05 16:33:23 Â 2015-05-05 18:45:26
How do i remove duplicate records from a table with a single query without using cursors or anything like that.Sample :tempCol11221P.S The table has only one column
I have a table that has duplicate records with the exception of the ID and I am trying to write a while loop that would go through the table, locate all duplicate records based on a field called LASTNAME.
I just discovered that all my records appear twice inside my table, inother words, they repeat on the row below. How can I delete all of theduplicates? I'm sure there must be a tidy line of sql to do that.Thanks,Bill
I uploaded some data about 2 or 3 times and it keep appending it to thetable.Now I want to keep only first duplicate and delete rest of.Suppose part number 123 has been added 3 times so I want to keep only 1record.Thanks
I loaded one table via SSIS and found that it contained many duplicate records (from the input source). I can create a SQL task to delete them, but I wonder if SSIS offers and task "out of the box" to delete dups?
Hello Frnds....Can anybody give the answer of this question as How to Delete duplicate records from Table ? I Know that with check option and also with Unique Constraint we can avoid to enter duplicate records in table but How to delete from table which does not have any constraints ?
any useful SQL Queries that might be used to identify lists of potential duplicate records in a table?
For example I have Client Database that includes a table dbo.Clients. This table contains various columns which could be used to identify possible duplicate records, such as Surname | Forenames | DateOfBirth | NINumber | PostalCode etc. . The data contained in these columns is not always exactly the same due to differences caused by user data entry; so some records may have missing data from some of the columns and there could be spelling differences too. Like the following examples:
1 | Smith | John Raymond | NULL | NI990946B | SW12 8TQ 2 | Smith | John | 06/03/1967 | NULL | SW12 8TQ 3 | Smith | Jon Raymond | 06/03/1967 | NI 99 09 46 B | SW12 8TQ
The problem is that whilst it is easy for a human being to review these 3 entries and conclude that they are most likely the same Client entered in to the database 3 times; I cannot find a reliable way of identifying them using a SQL Query.
I've considered using some sort of concatenation to a new column, minus white space and then using a "WHERE column_name LIKE pattern" query, but so far I can't get anything to work well enough. Fuzzy Logic maybe?
the results would produce a grid something like this for the example above:
ID | Surname | Forenames | DuplicateID | DupSurname | DupForenames 1 | Smith | John Raymond | 2 | Smith | John 1 | Smith | John Raymond | 3 | Smith | Jon Raymond 9 | Brown | Peter David | 343 | Brown | Pete D next batch of duplicates etc etc . . . .
I have table 'stores' that has 3 columns (storeid, article, doc), I have a second table 'allstores' that has 3 columns(storeid(always 'ALL'), article, doc). The stores table's storeid column will have a stores id, then will have multiple articles, and docs. The 'allstores' table will have 'all' in the store for every article and doc combination. This table is like the master lookup table for all possible article and doc combinations. The 'stores' table will have the actual article and doc per storeid.
What I am wanting to pull is all article, doc combinations that exist in the 'allstores' table, but do not exist in the 'stores' table, per storeid. So if the article/doc combination exists in the 'allstores' table and in the 'stores' table for storeid of 50 does not use that combination, but store 51 does, I want the output of storeid 50, and what combination does not exist for that storeid. I will try this example:
'allstores' 'Stores' storeid doc article storeid doc article ALL 0010 001 101 0010 001 ALL 0010 002 101 0010 002 ALL 0011 001 102 0011 002 ALL 0011 002
So I want the query to pull the one from 'allstores' that does not exist in 'stores' which in this case would the 3rd record "ALL 0011 001".
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.
I have written this script: What I want to do now is, with the new JOINED table find and display all the duplicates custID WHERE the price is either 100 OR 200. Can anyone help? I am very new to all this and can't see how to do it. Thanks!
SELECT * FROM table_customer T1 INNER JOIN table_itemsBought T2 ON T2.custID = T1.custID WHERE price = '100' OR price = '200';
Hi, I have had this problem for a while and have not been able solve it.
What im looking at doing is looping thru my patient table and trying to organise the patients in to there admission sequence, so when patient "A" comes in and is treated at my hospital and is discharged and admitted to another Hospital within one day then patient "A" will get a code of 1 being there first admission.
then if patient "A" is admitted again but there admission date is greater than one day they get a code of 2 being for there second admission but will need to loop thru table looking for other admissions and discharges.
The table name is Adm_disc_Match_tbl
Basically what i have 4 fields. Index_key = which is the patient common link (text) ur_episode = this wil change for each Hospital (text) Admission_datetime = patient admission date and time (datetime) Discharge_datetime = patient discharge date and time (datetime)
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
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:
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.
f_namef_countryf_ID ABCUS123 DEFGB123 ABCUS456 GHIGB789 etc.
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.
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.
