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?
View 2 RepliesWe have a table with 1 million rows with duplicates in a column which allows nulls.Can we enforce uniqueness for only future inserts by anyway(ignoring the old ones)?
Thanks!
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:
domainuser1;domainuser2;domainuser2;domainuser 3;
The need is to convert to this:
domainuser1;domainuser2;domainuser3;
I know that's a tall order.
With the data example below I am trying to consolidate the duplicate rows by flattening the dealer and billcode, or putting those values in each of the columns instead of creating separate rows...

My data is like below:
ClassId ClassName StudentId Subject SubjectId
1 ESL 12 English 20
1 ESL 13 Science 30
1 ESL 12 Social 40
1 ESL 12 Maths 50
Required output: parameters are Subject column values
ClassId ClassName TotalStudents SubjectIds
1 ESL 1 20, 40, 50
1 ESL 1 30
When one student takes multiple subjects then count student only once, so in the above data 12 is one student id takes multiple subjects so counted only once. TotalStudents value is 1
I did write below query:
Declare @subjectids string
set @subjectids = '20,30,40,50'
-- will split @subjectids and store in temp table
select classname, classid, Count(Distinct StudentId)
from mytable
where SubjectsIds in @subjectIds
group by ClassId, ClassName, SubjectId,
but it gives me below output:
ClassId ClassName TotalStudents SubjectIds
1 ESL 1 20
1 ESL 1 30
1 ESL 1 40
1 ESL 1 50
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.
I have 2 excel tables files.One table has info about sales by country, by model, by date...and the other table has units by date.Obviously, the common key is "date"....and by creating a relationship, I can add "units" to my combined resulting table.However, I can't create the relationship. Excel keeps telling me: "the relationship cannot be created because each column contains duplicate values. Select at least one column that contains only unique values".

I have a result set stored in a temporary table variable. The fields need to have heirarchy when they finaly get displayed to the user. I need to replace the repeating fields per group with NULL and leave out only one set of unique records per group.
I want to do something like this- make the fields in red NULL while leaving out the ones in green.
{ Col.Group I } { Col. Group II }
Col1 Col2 Col3 Col4 Col5
------- ------- ------- ------- -------
ValA ValA2 ValA3 ValA40 ValA50 {
ValA ValA2 ValA3 ValA40 ValA50 Row. Group A
ValA ValA2 ValA3 ValA41 ValA51 }
ValB ValB2 ValB3 ValB40 ValA50 { Row. Group B
ValB ValB2 ValB3 ValB41 ValA51 }
I was able to achieve this by using @@ROWCOUNT with in a while loop by performing one UPDATE at a time (SET ROWCOUNT = 1). But i have to run Count(*) each time I loop through the update query to figure out the remaining number of rows I have per group as I need to leave out one untouched. But the Count function is taking too much time and I'm having performace issues.
Any idea how I might be able to do this in my stored proc. efficiently?
Thanks,

When setting up an ODBC connection on a non-sql Server X and choosing from the drop down menu which SQL Server to connect to, I see two identical names for my SQL Server (Y). No matter which one I choose, Im not able to go to the screen after being asked how I want to log in (SQL server authentication)
If I build a ODBC connection from any other desktop, I only see one SQL Server Y, and am able to establish a connection to SQL Server Y, with the same user account and password as when Im on Server X.
Server X has two network cards and is teamed...could that be a possible problem ?
Any ideas ?...Thank you
We have SharePoint list which has, say, two columns. Column A and Column B.
Column A can have three values - red, blue & green.
Column B can have four values - pen, marker, pencil & highlighter.
A typical view of list can be:
Column A - Column B
red - pen
red - pencil
red - highlighter
blue - marker
blue - pencil
green - pen
green - highlighter
red - pen
blue - pencil
blue - highlighter

We are looking to create a report from SharePoint List using SSRS which has following view:
red blue green
pen 2 0 1
marker 0 1 0
pencil 1 3 0
highlighter 1 1 1
We tried Sum but not able to display in single row.
I have an SSIS package that imports data from an Excel file, replaces any value in Excel that reads "NULL" to "", then writes the data to a couple of databases.
What I have discovered today, is I have two columns of dates, an admit date and discharge date column, and what I need to do is anywhere I have a null value in the discharge date column, I have to replace it with the value in the admit date column.
I have searched around online and tried a few things using the Replace funtion in Derived columns but no dice so far.

Hi,
I want to insert data into table without duplicate values ..
how to do?
I have a table in which a non-primary key column has a unique index on it.
If I am inserting a record into this table with a duplicate column value for the indexed column, then what will be the error number of the error in above scenario? OR How could I find this out?
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

View 2 Replies View RelatedWe 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 want to extract only the duplicate values from a table

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
Pardon the newbie question...but I'm trying to load a dimension table in a small data mart that has columns in it that are unique to the dimension and not sourced from any source table. Two of those columns are date columns that I want to default to the system date and the other column I want to load with a default value. I can't figure out how to do this within a data flow task. The source columns flow from the input db source into a scd transform but I can't seem to edit the columns in the target table table if they don't actually come from a data source. There doesn't seem to be a data transform object to handle this.
Thanks.
I have one table with two columns, GUID and PID and another table with three columns, GUID, LastName, and FirstName. For each unique PID, I need to find the PID's that have more than one GUID and then match that with their respective FirstName and LastName from the other table.
Table1
GUID PID
GUID1 PID1
GUID1 PID1
GUID1 PID1
GUID2 PID1
GUID3 PID2
GUID3 PID2
GUID3 PID2
Table2
GUID LastName FirstName
GUID1 Mulder Fox
GUID2 Scully Dana
GUID3 Skinner Walter
So I'm looking for a result like:
PID1 GUID 1 Mulder Fox
----- GUID 2 Scully Dana

Hi there,I would like to know how to get rows with duplicate values in certaincolumns. Let's say I have a table called "Songs" with the followingcolumns:artistalbumtitlegenretrackNow I would like to show the duplicate songs to the user. I considersongs that have the same artist and the same title to be the same song.Note: All columns do not have to be the same.How would I accomplish that with SQL in SQL Server?Thanks to everyone reading this. I hope somebody has an answer. I'vealready searched the whole newsgroups, but couldn't find the solution.

The columns BCOM_ID contain unique values, but Venue_ID can have duplicate
values. I only want to get rows for one instance of the Venue_ID (per
BCOM_ID) - doesn't matter which instance but basically, no duplicates.
Oh yes, one of the columns is a Bit column.
Any ideas would be welcome & appreciated!
