Best Way To Add To DB While Checking For Duplicates
Jul 23, 2005
Situation:
Day 1
Table contains 100 items of actions imported via FTP. One of the fields
in the table can be updated to reflect an assigned unit code.
Day 2
Actions that may be duplicates of the table from Day 1 (with the
exception of the updated assigned unit field) are imported for
inclusion in the Table from Day 1.
Question- What is the best way to insure that any new items are added
to the table and that no duplicates are added at the sametime?
I'm wanting to create a if statement that will query a table and check for a duplicate and if there is a duplicate return that uniqueID or if it doesnt find a duplicate continue to add a new record...so here is my question is there a way to run a if statement that will call a function (lets say a function that returns like a bool) and if it finds a duplicate grab that id and store it in a session.....i guess my question is how do i query the database for a record and if found return true if not return false....that is my question....
how i can check for duplicate entries for example if a serial number has already been inputted and a user tries to input the same serial number.. how can i get a trigger or some sort to check for duplicates and then prompt that the number has already been entered.
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,
As you can see Col1 & Col2 ONLY do not make up the PK. I need to include Col3 as well. My concern is I am not sure if I have a row like.. 1...........2.......A......X reapeated lower down the order. So how do I figure the PK out?
I need some help. 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?
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
i'm trying to get duplicates out of the my database
SELECT COUNT(*) AS Amount, Firstname, surname, Internalextension FROM iac.dbo.sf_profil GROUP BY FirstName, surname, internalextension HAVING COUNT(*) > 1 order by firstname, surname
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 Pricing_Source, VaR_Identifier, Price_Date, PX_Last, Count(*) as 'count' from tblPricesClean group by Pricing_Source, VaR_Identifier, Price_Date, PX_Last having count(*) > 1 order by count desc
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
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)
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
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. It'sthe comment line:-- Need to find out how many hours the employee is scheduled etc.Also, there are no duplicate records in the Employee table nor theWeeklyProfile table. At least I assume so - if the following SQL todetect duplicates is correct!SELECT E.*FROMEmployee Ejoin(select EmployeeIDfromEmployeeGroup by EmployeeIDhaving count(*) > 1) as E2On(E.EmployeeID = E2.EmployeeID)SELECTW.*FROMWeekProfile Wjoin(SelectWeekProfileIDFROMWeekProfileGROUP BYEmployeeID, MondayHours, WeekProfileIDHAVING COUNT(*) > 1) AS W2ONW.WeekProfileID = W2.WeekProfileIDNOTE: In the second statement, I have tried for MondayHours thruFridayHours.Anyone got any ideas?

Can someone show me some C# code for detecting if a SQL row exists or not? This seems like a very typical action and I cannot for the life of me find a tutorial online that explains this step. In my code I'm either going to INSERT or UPDATE a record. I tried sending a SELECT command through a ExecuteNonQuery, but only got -1 as a response. Apparently ExecuteNonQuery does not work with SELECT. I then saw that T-SQL has an EXISTS keyword, but I cannot see anyway to use that from within C#.So...can anyone share the typical code they use to identify if a row exists or not within a database. I guess I was execting there to be some method available to do this sort of thing.
i want to check a value in 2 tables. the 1st table i want to check if the value exists and from the 2ed table i samething. i came up with this but when it's doing the second if i get error on the page.

Good morning everyone I am writing a windows forms application that will work similar to the windows messenger popup. I need this application to display a message to the user whenever a record is added to table in my DB. Any help would be appreciated in explaining how I can check the DB for new records.
I've forgotten the character set that I've chosen when I was installing the SQL Server 7. Is there a way to check?
I'm currently using US English version of Windows NT4 and SQL7. But interestingly, all the data is in Japanes characters. It's actually for a Japanese website, and the front-end application is written in ASP. I remember reading somewhere that it is impossible to do certain type of sorting (by some particular order for the Japanese language) as it is limited by the choice of the language of the NT OS.
The type of sorting that I'm looking at is the grouping of 5-characters. One example is in http://www.forest.impress.co.jp/aiueo.html
Would this be possible with my current setup? Or would it help if I migrate over to Windows 2000? (I'd rather not move to Japanese NT4)
Your feedback and advice would be very much appreciated!
Just a brief question. I have a script which does a number of insert statements. What I would like to do is determine if the insert statements were all successful. Aside from checking @@ERROR after every insert, is there a way to check if all the insert statements completed successfully?
I want to do a check to see if a number falls within a range specified by the user. Basically, they enter in a min and max value and I return a hit if a number falls inbetween.
I have having trouble with my SQL statement:
Code:
SELECT DISTINCT * FROM Table WHERE ( (0=0) AND (min.value <= Table.Value <= max.value) )
(This isn't my actual code, but just the logic)
It will return all the results everytime. Does anyone have any suggestions on what I could be missing here?
I have a question I hope someone can help me with.
My situation: I have a single-step job in SQL Server, which runs a stored procedure, A. This stored procedure invokes another stored procedure, B. In B, one of the statements is a 'BACKUP DATABASE' command, and a database is backed up to a file.
The job is started by an application. Once started, the application then uses the SQL-DMO property CurrentRunStatus to periodically check the status of the job. When the property returns the value SQLDMOJobExecution_Idle (indicating the job has completed), the application code then continues processing, and attempts to access the .dat file produced by the 'BACKUP DATABASE' command.
My problem: On occasion, the application will hit the problem where either the backup file cannot be located, or the file is still being locked by another process (Error=The process cannot access the file because it is being used by another process).
Is anyone able to shed some light on this?
I assume that the job will only return a completed status after: (a) both A and B have completed execution, and (b) the BACKUP operation has completed
Is it possible that even though SQL Server indicates the job has finished, that the BACKUP operation still hasn't completely ended?
I have around 25 sql servers(sql server 2000) all on windows server 2003. i would like to know if anyone has a script that will poll all the servers and check to make sure the agent is running.
I need to check one table while updating another table suppose i need to check table1's value is whether less then 0 or not without if condition can i check it with update query? thank you
I have a table that I know has a null or nothing in a field. When I run this query to get a list of them nothing comes back at all but it doesn't error out. Any ideas?
select * from lab_test_add_conf where table_name = null order by lab_test_conf_id
This is going to sound ignorant but... I had a look here http://support.microsoft.com/?id=321185
And one thing isn't clear. How doe you know if the 32-bit or 64-bit version was installed?
