Stopping Duplicate Values From A Junction Table
Mar 1, 2008
Hi i have a junction table(UserGroups) which is linking my "users" table with my "groups" table, however when the information is coming back in the format below, instead i want the group names to appear in only one field, instead of repeating the same data, could someone please tell me what i need to change.
UserName: Edwin Carols
UserAge: 28
JobTitle: Manager
GroupName: MUFC
UserName: Edwin Carols
UserAge: 28
JobTitle: Manager
GroupName: AFC
Below is my SQL statement;
Code:
SELECT Users.UserName,Users.UserAge, Users.JobTitle, Groups.GroupName FROM Users INNER JOIN UserGroups ON Users.UserID = UserGroups.UserID INNER JOIN Groups ON UserGroups.GroupID = Groups.GroupID WHERE (Users.UserID = '5')
And my table structure is like;
Users; UserID, UserName, UserAge
Groups; GroupID, GroupName
UserGroups; UserGroupID, UserID, GroupID

[RS 2005]
Given the starting and stopping points (time values), how do I generate values between these points.
For example, if I have 08 (representing Hour) as a starting point and 12 as a stopping point.
From this I would like to generate a data sequence like 08, 09, 10, 11, and 12.
So how do I accomplish this? In SQL or in the RS?
The only thing I can think of is using a WHILE loop and a temporary table in SQL (not to keen on doing this).

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 two tables. A table called users (content speaks by it self) and a table called groups.
Since i want every user to be able to be a member of several groups and, of course, a group to have several users i have made a junction table called jt.
The junction table contains userId's and groupId's according to the user-group bindings. The primary key(identity) in the junction table is a int named jtId.
Now i want to take out all posts from the junctiontable and the corrresponding userName (s) from the users-table and the corresponding groupName from the groups-table.
Can somebody please help me to make a SQL command that will di that for me. I have tried with INNER JOIN and several SELECTS in the same command.
Thanks in advance, Greetings from Esben

I am trying to update 2 tables at the same time by adding new records to them and then making sure that they are related on my junction table?
Table1
packageID
Packagename
Table2 (JunctionTable)
PackageID
JobID
Table3
JobID
JobName
And I want to create a new package and new Job Name at the same time I would need to make multiple insert statements
First take care of the new Package
INSERT INTO Table1 (PackageName) Value (@PackageName)
Then Take Care of the JobName
INSERT INTO Table3 (JobName) Value (@JobName)
Finally marry the two together
but how?

Looking for some help here, so thanks for any input. I'm a painfully new newbie to SQL scripting.Situation:
I have a simple database to handle an organization's events. Those
events are categorized and may have more than one category assigned to
each event. I need a maintenance Web Form to update their events.Set
Up (so far): I have a CATEGORIES table. It has an auto incrementing UID
and a Category name field. This table will be updated so infrequently,
I plan to update it manually (no need for a maintenance Web Form). Next
is the EVENTS table. It also has an auto incrementing UID along with
several fields (Title, Location, DateTime, etc.). The junction table is
named jEVENTSCATEGORIES. It has its own auto incrementing UID along
with 2 fields named for the primary keys (UIDs) in the other 2 tables
(EventsID and CategoryID).Goal: On the Web Form, I have a
CheckBoxList control that's populated by the CATEGORIES table. One or
more categories can be checked for each event. I have a FormView
control that allows Edits and Inserts.Need: I need to know the
INSERT statement(s) required to insert a new record in the EVENTS table
and then to update one or more rows in the junction table
(jEVENTSCATEGORIES).My Assumptions: I know how to create
SELECTs and INSERTs and whatnot, but I'm not certain how to create a
second INSERT statement that is based on a variable (or output) from a
previous action. So any help would be MUCH appreciated. Thanks for your
time!

As an example, I am building an authentication mechanisim that will usedata in the 3 left tables to determine rights to objects in adestination table, diagrammed below. In this structure, multiplerecords in the left tables will point to multiple records in the righttable. Normally, I would approach this problem using junction tables(LeftID, RightID) to create many-to-many joins.However, given the structure of each table is nearly identical (as faras the linking IDs are concerned), I could also use a single junctiontable with columns for each available table ID (LeftID1, LeftID2,LeftID3, RightID). In this table, only two IDs would be utilized perrow (LeftIDx -> RightID).In both designs, the needed rights information is returned from fairlysimple views, thus the end result is equivalent. The advantage to thesecond, multi-ID junction table design, is a simpler databasestructure. However, never using this approach before, I am unsure ofthe potential future performance impacts.Any significant downsides to this second design? Examples of anabbreviated structure follow:Data Tables-----------LeftTable1LeftID1 (int)Data1LeftTable2LeftID2 (int)Data2LeftTable3LeftID3 (int)Data3DestinationTableRightID (int)DataLinking tables option 1-----------------------JunctionTable1LeftID1RightIDJunctionTable2LeftID3RightIDJunctionTable3LeftID3RightIDLinking table option 2----------------------JunctionID1 (int)ID2 (int)ID3 (int)DestinationID (int)

Hi all,
This is a bit of a general question regarding SQL Server link tables that i hope someone can find the time to answer.
I am looking for the best practice. If I have 3 tables
1) tblCompetition
2) tblTeams
3) tblTeamsInCompetition (this is the link table)
I know the link table should have a related CompetitionID and TeamID,
but should the link table also have a primary key that is an identity
autoincrement by 1 just as you would with the other two tables. In
Access I have never done this, however in SQL Server I have read that
you should do this (but now I can't find the documentation again which
prompts me to ask the question here).
Thanks for taking the time to answer this question.

Hello,
This seems like such a simple problem but I am new developer even through I have been on the administration end of things for some time. I will go into more detail about my tables and there relationships below. Anyway, I am trying to create a many-to-many relationship within ms sql server 2005. I have created both of my primary tables and also a junction table per the directions on microsoft's website all per ms's instructions as stated here...
http://msdn2.microsoft.com/en-us/library/ms178043.aspx
At then end of these instruction it states as a NOTE: The creation of a junction table in a database diagram does not insert data from the related tables into the junction table. For information about inserting data into a table, see How to: Create Insert Results Queries (Visual Database Tools).
http://msdn2.microsoft.com/en-us/library/ms189098.aspx
and these directions do not go into detail on how to do an insert on a junction table. And I cant find out how to do this anywhere on the internet... I did create a T-SQL INSERT statement in a trigger as listed below but I end up getting an error AS LISTED BELOW....
Here is how I set everything up...
PetitionSet table consists of:
PetitionSetID int auto-increment primary key
PetitionSetName varchar(50) no nulls
PetitionSetScope varchar(50) no nulls
the Petition table consists of:
PetitionID int auto-increment primary key
PetitionSetID int no nulls
PetitionName varchar(50) no nulls
the SetToPetitionJunction table consists of:
PetitionSetID int
PetitionID int
And, there is a composite key made up of both the PetitionSetID and PetitionID fields.
I have created the foreign key relationships with DEFAULT VALUES from the SetToPetitionJunction table to each column's respective corresponding column in each of the tables: PetitionSet and Petition.
The trigger is on the Petition table and it has the following code:
set ANSI_NULLS ON
set QUOTED_IDENTIFIER ON
go
-- =============================================
-- Author: Name
-- Create date:
-- Description:
-- =============================================
ALTER TRIGGER .[SetToPetitionJunctionTrigger]
ON .[dbo].[Petition]
AFTER INSERT
AS
BEGIN
-- SET NOCOUNT ON added to prevent extra result sets from
-- interfering with SELECT statements.
SET NOCOUNT ON;
INSERT INTO SetToPetitionJunction
(PetitionID, PetitionSetID)
SELECT Petition.PetitionID, PetitionSet.PetitionSetID
FROM Petition INNER JOIN
PetitionSet ON Petition.PetitionSetID = PetitionSet.PetitionSetID
END
I have created an asp.net 2.0 front end to insert values into the PetitionSet table and the Petition Table. And in the detailsview for the Petition table I manually insert the PetitionSetID field to the number that corresponds to an auto-generated number on the primary key of the PetitionSet table. So I am maintaining referential integrity...
The first time it works and inserts one record in the Junction table containing the PetitionSetID from the PetitionSet table and the PetitionID from the petition table.
Then when I try to add in another petition for the same petition set number just like I did the first time and then I get this error...
Violation of PRIMARY KEY constraint 'PK_SetToPetitionJunction'. Cannot insert duplicate key in object 'dbo.SetToPetitionJunction'.
The statement has been terminated.

Hello specialists.
Maybe this is the wrong formum but I've got a question for which you probably have the answer, i hope.
Situation
------------
John is member of Group_A and Group_B
Bill is member of Group_B and Group_C
Allison is member of Group_A and Group_E
How can I create a query to input Allisons username into table 1 and groupmembership into table 2. Also updating the relationship within junction-table3 must be done automaticaly. I want to avoid duplicate records.
The final situation I want is given in red text.
The relationships between the tables are as follows
-------------------------------------------------------------
Table1 (PK)ID-Userinfo [ONE] <------------> [MANY] Table3 ID-Userinfo
Table3 (PK)ID-GroupInfo [MANY] <------------> [ONE] Table2 (PK)ID-GroupInfo
Table1: UserInfo
------------------------------
(PK)ID-Userinfo UserName
1 John
2 Bill
3 Allison
Table2: GroupInfo
------------------------------
(PK)ID-GroupInfo GroupName
1 Group_A
2 Group_B
3 Group_C
4 Group_E
Table3: MemberOf
------------------------------
(PK)ID-MemberOf ID-UserInfo ID-GroupInfo
1 1 1
2 1 2
3 2 2
4 2 3
5 3 1
6 3 4
I hope you can help me cracking this nut.
Thx in advance. Greetings Fred

Hello Everyone:
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.
How do I fix this?
TIA

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

I have 2 identical tables one contains current settings, the other contains all historical settings.I could create a union view to display the current values from table A and all historical values from table B, butthat would also require a Variable to hold the tblid for both select statements.
Q. Can this be done with one joined or conditional select statement?
DECLARE @tblid int = 501
SELECT 1,2,3,4,'CurrentSetting'
FROM TableA ta
WHERE tblid = @tblid
UNION
SELECT 1,2,3,4,'PreviosSetting'

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?
