Comparing Similar Tables - Removing Duplicate Or Repeated Data
Sep 30, 2007
It seems that there should be a solution for my situation, but for the life of me I can't seem to figure it out.
I need to compare two "like" tables, containing similar data. Tbl 1 is "BOOKED" (which is a snapshot of inventory) and tbl 2 is "CURRENT" (the live - working inventory table). If I write my query as follows the the subsequent result is "duplicate" data.
Code Block
SELECT booked.item, booked.bin, booked.quantity, current.bin, current.quantity
FROM BOOKED
LEFT JOIN
CURRENT
ON booked.item = current.item
No matter what type of join I use, there is duplicate data displayed for each table. For example, if there are more bins in the BOOKED table that contain a certain product then the CURRENT table will repeat data and vica versa.
As follows:
Item
Bin
Quantity
Bin
Quantity
12345
A01
500
A01
7680
12345
B01
6
A01
7680
12345
C01

98765
Y15
2500
Y15
3000
98765
X10
1200
Y15
3000
What I would like to do is display Bin and Quantity only once and the repeating values as NULL or [BLANK]. Or, to display all of the bins from both tables and only the quantities from each table in relation to the bin found in that table, returning a "0" if no quantity exists.
This is what I'm after:
Item
Bin
Quantity
Bin
Quantity
12345
A01
500
A01
7680
12345
B01

Is this possible? If so, how?
I also might add that it is ok for each table to contain multiple entries for any given item. This is basically being requested as an inventory variance report - inventory before physical count and immediatly after physical count - and will only be run once a year.

Just thinking out loud here:
What if I created three subqueries, the first containing only BOOKED information, the second containing only CURRENT information and the third being a UNION of both tables? Something like this:
Code Block
SELECT q3.bin, q1.item, ISNULL(q1.quantity, 0) as QTY_BEFORE, ISNULL(q2.quantity, 0) as QTY_AFTER
FROM
(select item, bin, quantity
from BOOKED)q1
Left Join
(select item, bin, quantity
from CURRENT)q2
on q1.item = q2.item
Left Join
(select bin, item
from BOOKED
UNION
CURRENT)q3
on q1.item = q3.item
Order By q1.item
I don't know if I wrote the UNION statement correctly, but I will have to try this when I get back to work...
I am trying to write an SQL command for my crystal report. I need to compare the same column in 3different tables & get the data from each table for only the matching data.. I understand I need to create a temporary table, get the data into it & then work around.. I am quite new to SQL.
Eg: Considering one customer account Table 1 Cust.No Name Amt_Counter AmtPaid 123.456 sam 0 0 123.456 sam 1 50
Table 2 Cust.No Name Freq_Counter Frequency 123.456 sam 1 0 123.456 sam 2 15
I am running a query on multiple tables and the data I get back consists of several repeated rows but with one column different. I want to take out those repeated rows and for the column that is different join that data and separate it by a comma. Can this be done?
Ex. Cindy Lair 111 Drury Circle Harrisburg Pennsylvania 717 Cindy Lair 111 Drury Circle Harrisburg Pennsylvania 610 Cindy Lair 111 Drury Circle Harrisburg Pennsylvania 310
So i would like this data to come up as: Cindy Lair 111 Drury Circle Harrisburg Pennsylvania 717,610,310
I have a table that I am basically reduplicating a couple of times for each part of this database that I want to create.Each table basically has the same data: The tables will be called motherTable, fatherTable, sonTable, daughterTable and so on.I am pretty much using the following in each column: UserID, MotherID(or FatherID or SonID, etc., etc. and so on for each unique table), FirstName, LastName, MiddleName, BirthPlace, Photo, Age.I don't see an option to copy a table and just modify the second ID part and rename that table accordingly.How can I make this an easier way of creating these similar tables without retyping all these columns over and over again?Thanks in advance.
I have two tables in my database called CartItems and OrderItems. Istore all of a session's shopping cart items in the CartItems tableusing the sessionID as the identifier (called cartID in my DB). Afteran order is placed and is approved, I would like to copy all of theitems in the CartItems table for that given cartID to the OrderItemstable given a new orderID.I will know the cartID and orderID ahead of time and would like tosend them both into a stored procedure and have the transfer takeplace.Example:take this data...CartItems (table)--------------------------------------cartID | itemID | quantity | price--------------------------------------12345 2 1 12.9512345 7 2 17.95and make it this data...OrderItems (table)--------------------------------------orderID | itemID | quantity | price--------------------------------------00001 2 1 12.9500001 7 2 17.95via some stored procedure that I send (@cartID,@orderID)Any help would be greatly appreciated!!
I would like to compare data across two tables. I have partinformation in a table. I get a new set of information periodically.I would like to compare my new info to my old info. I recognize thatdoing a compare of every attribute of every part will take FOREVER. Isthere some way I can do a "diff" based on the columns that I careabout?Thanks!--gloria
I am looking for an efficient mechanism to compare data between 2 tables/views.
Rationale: I use a proprietary tool to data transfer between 2 databases. The tool itself uses Microsoft SSIS (integration service) to transfer data. I want to make sure that the data is transfered properly. Both the source and target database are not live database. The source and target database are in seperate servers.
I have recently converted my DTS packages to SSIS and deployed them to the new server. I have the 2000 and 2005 server running concurrently, all that is left for me to do is compare the the tables generated by the DTS and SSIS packages to see if they are the same.
How do I go about comparing the tables, which are from two different servers using SQL server 2005?
I have two tables of book information. One that has descriptions of thebook in it, and the isbn, and the other that has the book title,inventory data, prices, the isbn.Because of some techncal constraints I won't get into now, I can'tcombine them both into one table. No problem. Things are going fine aslong as there is a description in the one table to corrispond to theisbn and other data in the other table.However, about half of the products are not yet entered into thedescrition table. I'd like to run a sql query that pulls up all theisbns that don't exist in the other. In other words, I'd like to get aquery that tells me exactly which isbns do not yet have descrition datain them. I know there is some sql that says to search from one filewhere the number does not exist in the other, but it slips my mind. Cansomeone help me on this please?Thank you!Bill*** Sent via Developersdex http://www.developersdex.com ***Don't just participate in USENET...get rewarded for it!
I have found a bunch of duplicate records in our housing database that ideally I need to delete.There are two tables that I need to remove data from ih_cml_log_entry and ih_cml_log_notes. There is no unique identifier between the tables for a log entry. So I have had to join on the person_ref, log_seq and the date/time of entry.How do I go about deleting the data - I've used the script below to identify what I need to delete -
SELECT * FROM ( select cml.person_ref, cml.open_date + open_time as 'datetime',cml.open_user,cml.log_type ,ROW_NUMBER() OVER (PARTITION BY cml.person_ref, cml.open_date + cml.open_time,cml.open_user,cml.log_type ORDER BY (SELECT 0)) AS RowNo ,n.note FROM ih_cml_log_entry cml

Hi all, I have one table in which one column contains duplicate values. My question is how i can use T-SQL so that i can retrive values for all columns in the table which are distinct and retriving the single value from column which contains duplicate values.
Please give the DML to SELECT the rows avoiding the duplicate rows. Since there is a text column in the table, I couldn't use aggregate function, group by (OR) DISTINCT for processing.
Table :
create table test(col1 int, col2 text) go insert into test values(1, 'abc') go insert into test values(2, 'abc') go insert into test values(2, 'abc') go insert into test values(4, 'dbc') go
I want the output like this,it should take only Min Datecreated FormCodeRefCodeSerialnoDateTime R1-196H1-68A12232138/6/2007 19:38:14 R1-205H1-67XS23124148/6/2007 19:36:08 R1-220H1-66F433365348/6/2007 19:30:27 R1-400H1-64ER53436648/6/2007 19:24:23 R1-408H1-65TE4626268/6/2007 19:24:23

for each 7530568 ordernumber there should only be one OESCHD status.
This is the query I'm using to insert the data sent to me.
INSERT INTO ORDER_EVENTS SELECT d.division as division, dt.orderNum as orderNum, dt.poNum as poNum, dt.statusCode as statusCode, dt.statusChangeDate as statusChangeDate FROM dt_Order_Events dt INNER JOIN division d ON dt.division = d.divisionShort INNER JOIN status s ON s.division = d.division AND s.statCode = dt.statusCode WHERE directive <> 'C' AND dt.orderNum IN (SELECT orderNum FROM ORDER_HEADER)
This works fine when used with in the hourly transactional update. But When I ran it for the Bulk UpDate (so we'd have historical data) it allowed orders to have statuses to many times.
I am not a SQL guru, I have no idea how to write a sql statement or stored proc that will remove the duplicate records. or how to change what I have to prevent further ones.
I am having a 1st listbox which is populating production lines, 2nd combobox to populate the production units. From here , the user will be able to select multiple production units from the combobox and hence populate the variable in listbox 3.
This is the query that I'm using to query on the variable table: 'SELECT DISTINCT PU_Id,Var_Id,Var_Desc from Variables where PU_Id IN (@ProductionUnits)'
The problem now is that this would return all the variables for the selected production units and for those variables that have the same name, they would appear in the listbox as duplicates.
I wonder if there's any way to filter off or remove the duplicates in the listbox 3 by using sql query?
Hi, I have results from a survey in a table, every entry is assigned a unique ID. I want to remove duplicate entries based on the survey data but not on the unique ID (obviously). So far I have...SELECT DISTINCT RespondantID, Q1, Q2, Q3, Q4, Q5, Q6, Q7, Q8, Q9, Q10, Q11, Q12, Q13 FROM Results But that gives...
1 - Anonymous 1 1 1 1 1 1 1 1 1 1 1 1 1
2 - Anonymous 2 2 2 2 2 2 2 2 2 2 2 2 2
3 - Martin 2 2 2 2 2 2 2 2 2 2 2 2 2 I.e. in the above example, it would seem that 'Martin' submitted his data once and then submitted it again with his name. How can I remove the '2 - Anonymous' frrom the data set? Thanks!
I am trying to get people from my table that have closed accounts. However, in my table many people have more than one account. They will have multiple closed accounts and some active accounts. I need to get the people with only closed accounts.
Values in the table
Code: name surname status Closed Number ----------- --------- ----------- ------------- ---------------------------- Jeff Burns closed 2012/01/01 142 Tina Drewmor closed 2008/05/20 546 Jeff Burns active 1900/01/01 354 Kyle Higgin active 1900/01/01 851 Tina Drewmor closed 2009/04/14 154
The query I am using so far is:
Code: select d.name, d.surname, s.status, s.closed, s.number from d d inner join s s on d.number = s.number where s.status = 'closed'
What I need to see in the results
Code: name surname status Closed Number ----------- --------- ----------- ------------ ----------------------------- Tina Drewmor closed 2008/05/20 546 Tina Drewmor closed 2009/04/14 154
I have regular work that requires me to extract a bunch of customer records from our database, and then remove duplicate address destinations (so we dont mail the same address more than once).
I can currently achieve this using a combination of my poor SQL skills and Excel, but it's really not working out for me, so looking for SQL wizardry necessary to do it just in SQL.
Relevant fields: Member.AddressBarcode (This is a unique barcode (Text representation of a base-3 number) based on the customer address. So if there's more than one record in the pulled records with the same barcode, we then look at Member.MemberTypeID to determine whether to include this record in the results or discard it as a duplicate. Note that AddressBarcode may be blank if the mailing address couldn't be validated, if it is blank we don't discard it since there is no easy way to detect duplicate addresses without the barcode)
Member.MemberTypeID (This is the type of member account. We have 3 types - Single, Joint Primary, Joint Secondary, represented in this field by the numbers 1/2/3. This is also the order of preference of who to mail. So if there is a Joint Primary and Joint Secondary with the same mailing barcode, we want to discard the Joint Secondary from the results, so that the Joint Primary is the record we include in the results of who to mail.)
Member.ID (Unique numeric ID for each customer. Kind of irrelevant here, but it's a key)
So some pseudo code for what I'm trying to achieve is:
(Member.MemberTypeID = 1) OR (Member.MemberTypeID = 2 AND Member.AddressBarcode not in results of Member.MemberTypeID = 1) OR (Member.MemberTypeID = 3 AND Member.AddressBarcode not in results of Member.MemberTypeID = 2 AND Member.AddressBarcode not in results of Member.MemberTypeID = 1)
Below is a snippet of MS SQL inside some VB that retieves Commodity info such as product names and related information and returns the results in an ASP Page. My problem is that with certain searches, elements returned in the synonym field repeat. For instance, on a correct search I get green, red, blue, and yellow which is correct. On another similar search with different commodity say for material, I get Plastic, Glass,Sand - Plastic, Glass,Sand - Plastic, Glass, Sand. I want to remove the repeating elements returned in this field. IOW, I just need one set of Plastic, Glass and Sand. I hope this makes sense.
Below is the SQL and the results from the returned page.
PS I tried to use distinct but with no luck I want just one of each in the example below.
Thanks in Advance!

hi All, I have to remove non-useful and duplicate records containing NULL , Blanks and extra spaces (either on left or right side of the column values) etc from all the tables in my server's DB XYZ weekly thru a a scheduled job with the help of a Stored Proc, that s i guess called Purging og DB. Plz help how i can do it with T-SQL.
Also i have to find out and remove all the duplicate DB objects(tables) from the DB .e.g. a table existing with name TABLE_TEST or TABLE_DEBUG etc for an original table TABLE , making sure no any of the base table is dropped.
What is the best way to compare two entries in a single table wherethe two fields are "almost" the same?For example, I would like to write a query that would compare thefirst two words in a "company" field. If they are the same, I wouldlike to output them.For example, "20th Century" and "20th Century Fox" in the companyfield would be the same.How do I do this? Do I need to use a cursor? Is it as simple as using"Like?"
Hi, Please help me with an SQL Query that fetches all the records from the three tables but a unique record for each forum and topicid with the maximum lastpostdate. Please provide separate solutions for SqlServer2000/2005. I have four tables namely – Forums,Topics,Threads and Messages in SQL Server2000 (scripts for table creation and insertion of test data given at the end). Now, I have formulated a query as below :- SELECT Forums.forumid AS ForumID,Topics.topicid AS TopicID,Topics.name AS TopicName,LastPosts.date as LastPostDate,LastPosts.author AS Author, (select count(threadid) from Threads where Threads.topicid=Topics.topicid) as NoOfThreads FROM Forums JOIN Topics ON Forums.forumid=Topics.forumid LEFT OUTER JOIN ( SELECT Topics.forumid,Threads.topicid,Messages.date,Messages.author FROM Topics INNER JOIN Threads ON Topics.topicid = Threads.topicid INNER JOIN Messages ON Threads.threadid=Messages.threadid WHERE Messages.date=(SELECT MAX(date) FROM Messages WHERE Messages.threadid = Threads.threadid) ) as LastPosts ON LastPosts.forumid = Topics.forumid AND LastPosts.topicid = Topics.topicid Whose result set is as below:-
forumid topicid name LastPostDate author NoOfThreads
5 17 General NULL NULL 0 I want all the rows from the Forums,Topics and Threads table and the row with the maximum date (the last post date of the message) from the Messages table as shown above. When I use the query by using only three tables namely Forums,Topics and Threads, I get the correct result. The query is as:- SELECT Topics.forumid AS ForumID,Forums.name AS ForumName,Topics.topicid as TopicID,Topics.name as TopicName, LastPosts.author AS Author,LastPosts.lastpostdate AS LastPost, (select count(threadid) from threads where Threads.topicid=Topics.topicid) as NoOfThreads FROM Forums JOIN Topics ON Forums.forumid=Topics.forumid LEFT OUTER JOIN ( SELECT Topics.forumid, Threads.topicid, Threads.lastpostdate, Threads.author FROM Threads INNER JOIN Topics ON Topics.topicid = Threads.topicid WHERE Threads.lastpostdate IN (SELECT MAX(lastpostdate) FROM threads WHERE Topics.topicid = Threads.topicid) ) AS LastPosts ON LastPosts.forumid = Topics.forumid AND LastPosts.topicid = Topics.topicid Whose result set is as:-

I have a stored procedure that returns a single row based on a parameter of employee ID. This particular procedure uses a CTE to traverse our org structure. One of the columns is returning a delimited string of Windows login values and due to the business rules, it can contain duplicate values. I need to have that column contain only unique values - no dupes.
For example, this one column could contain something like this:
Hi,Say I have a table Job with columns name, date, salary . I want to getthe name ,date and salary for the date when that person earned maximumsalary. I am using something likeSELECT X.name,X.date,X.salaryFROM job XWHERE X.salary IN(SELECT MAX(Y.salary) FROM job Y where Y.name= X.name);The problem is ; if a person earns maximum salary on two dates, both ofthe dates are printed. I just want to get any one of those two rows.I triedSELECT X.name,Min(X.date),X.salaryFROM job XWHERE X.salary IN(SELECT MAX(Y.salary) FROM job Y where Y.name= X.name);but it gives error.Can anybody please suggest a solution?Regards,Aamir
I have tested the code below to remove duplicate table entries based on the field IntOOS. This code works; however, I want to ensure I am removing the oldest entries and keeping the most recent entry. The field to key on this would be something like Max(ID). What would be the best way to ensure I keep the most recent table entry?
/*** Removes duplicate rows from ampfm.rpt_AdtVisitDiag table

;WITH CTE

SELECT
ROW_NUMBER() OVER (Partition By IntOOS Order BY IntOOS) AS ROWID
I need write a query for removing duplicates, for Example in my table I have columns
A_ID name id 1 sam 10 2 sam 10 3 sam 10 4 sam 10 5 ccc 15 6 ccc 15 7 ccc 15 8 fff 20 9 fff 20 10 fff 20
So now I have duplicates values in id column so now I need to take only one value of each and delete the remaining. I need to take first id value 10,15,20 so only 3 rows should be there in my table.
There are more than hundred tables, so i wanna automate this. i am tryin to do this in a cursor: please guide!
declare @name VARCHAR (50) declare cur cursor fast_forward for select name from sysobjects where type='u' and status not like '-%' open cur WHILE (1=1) BEGIN FETCH NEXT FROM cur INTO @name IF @@fetch_status = 0 BEGIN ALTER TABLE @name ADD created_by [VARCHAR] (25) GO ALTER TABLE @name ADD created_by [VARCHAR] (25) GO ALTER TABLE @name ADD created_date [DATETIME] GO ALTER TABLE @name ADD modified_by [VARCHAR] (25) GO ALTER TABLE @name ADD modified_date [DATETIME] END ELSE BREAK END DEALLOCATE cur
I also want that if one column for a table exists; the other columns should be created rather than it quits.
I have a table that I am basically reduplicating a couple of times for each part of this database that I want to create.
Each table basically has the same data: The tables will be called motherTable, fatherTable, sonTable, daughterTable and so on.
I am pretty much using the following in each column: UserID, MotherID(or FatherID or SonID, etc., etc. and so on for each unique table), FirstName, LastName, MiddleName, BirthPlace, Photo, Age.
I don't see an option to copy a table and just modify the second ID part and rename that table accordingly.
How can I make this an easier way of creating these similar tables without retyping all these columns over and over again?
