Retrieving Data From A Junction Table

Jan 30, 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; 

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')

SQL Query Question : How To Add Data To Two Tables Connected By Third Junction-table.

May 1, 2008


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

Junction Table SQL Sentence - Please Help Me Out

Feb 17, 2006

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

INSERT Among 3 Tables And 1 Is A Junction Table

Sep 23, 2007

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!

Junction Table Design Options

Jul 20, 2005

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)

Retrieving Data From SQL Table

Feb 5, 2008

 this is a simple problem but it's just driving me mad as it's not reading from my dB. basically, I've have reviews stored in my dB and want to display them in a textbox by clicking on a button called btnReviews. I think the problem might be that there is too much text stored per row of the table (as it is a review), but I have the datatype set as text in sql. here's the simple un-errorred code I have behind the button. any ideas where I went wrong. i've a feeling it's something small but it's just taken too long to figure out.protected void btnReviews_Click(object sender, EventArgs e)    {        String strConn = ConfigurationManager.ConnectionStrings["conLocalDatabase"].ConnectionString;        SqlConnection dbConnection = new SqlConnection(strConn);        SqlCommand dbCommand = new SqlCommand("Select [ReviewC] From [Review])", dbConnection);          dbCommand.Parameters.AddWithValue("Review", txtReviewView.Text);        try        {            dbConnection.Open();            dbCommand.ExecuteNonQuery();        }        catch (SqlException ex)        {            Console.WriteLine(ex.ToString());        }        finally        {            if (dbConnection != null)            {                dbConnection.Close();            }        }            }

Junction/link Table Primary Key: Best Practice Using SQL Server

Nov 30, 2005

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.

Retrieving Hierarchical Data From A Single Table

Sep 3, 2006

I would like to retrieve a hierarchical list of Product Categories from a single table where the primary key is a ProductCategoryId (int) and there is an index on a ParentProductCategoryId (int) field. In other words, I have a self-referencing table. Categories at the top level of the hierarchy have a ParentProductCategoryId of zero (0). I would like to display the list in a TreeView or similar hierarchical data display control.Is there a way to retrieve the rows in hierarchical order, sorted by CategoryName within level?

Insert Statement For Junction Table On Many To Many Relationship Ms Sql Server 2005

Oct 10, 2007

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.

SQL - Retrieving Same Table Twice

Jan 5, 2006

Hi,

I have a giant SQL query that retrieves a bunch of information from a couple of tables for use on a page, and I would like some help on constructing the SQL to get exactly what I have in mind. I have a table - called scContacts - that contains a list of contacts with detailed information. The contacts in the table are regular sales contacts, sales reps, and sales managers. Another table - called scCompany - contains a list of companies with detailed information.

For each company, we have a certain sales manager (or user) pertaining to that company as well as potentially a certain rep. The problem is that the contact tied to the company, the sales manager tied to the company, and the rep tied to the company all come from the same table. Here is the base SQL code I've used to get everything but the sales rep's name and sales manager's name:

----- SQL CODE -----
SELECT DISTINCT
scContacts.ID,
scContacts.inheritCoAddr,
scContacts.fName,
scContacts.lName,
scContacts.contact,
scContacts.billToAddress1,
scContacts.billToAddress2,
scContacts.billToState,
scContacts.billToZip,
scContacts.billToCity,
scContacts.billToCounty,
scContacts.billToCountry,

scCompany.ID AS companyID,
scCompany.companyName,
scCompany.companyURL,
scCompany.billToAddress1 AS companyAddress1,
scCompany.billToAddress2 AS companyAddress2,
scCompany.billToCity AS companyCity,
scCompany.billToState AS companyState,
scCompany.billToZip AS companyZip,
scCompany.billToCounty AS companyCounty,
scCompany.billToCountry AS companyCountry,
scCompany.businessType,
scCompany.phoneExt,
scCompany.phoneNum,
scCompany.faxNum,
scCompany.minEmployees,
scCompany.maxEmployees,
scCompany.actionTypeMAX,
scCompany.actionDateMAX,
scCompany.actionTimeMAX,
scCompany.statusID,
scCompany.userID,
scCompany.repID

FROM
scCompany,
scContacts

INNER JOIN
scStatus ON
scStatus.ID = scCompany.statusID

WHERE
scgroupContacts.contactID = [insert cookie value]
AND
scgroups.ID = [insert cookie value]
AND
scCompany.ID = scContacts.companyID
AND
scCompany.groupID = scgroups.ID
----- END SQL CODE -----

As indicated right now, this SQL code will retrieve all of the contact and company information for a certain contact ID which comes from a cookie value (inserted in ASP). I want to get the [fName] and [lName] fields from scContacts table where the scContacts.ID = scCompany.userID, and I also want those same fields from scContacts table again where the scContacts.ID = scCompany.repID. It would be simplest and most efficient if I could do this all at once (and I'm sure it's possible). How would I change the SQL to bring in that information from the same table two more times, tying their ID's to ID's in the company table?

thanks,
mellamokb

Retrieving Data

Jun 15, 2004

Hi

I've got a module that contains the following function.
Imports System.Data.SqlClient

Module SQL_Sprocs
Function ListUsers()

Dim conn As New SqlConnection(System.Configuration.ConfigurationSettings.AppSettings("DBConn"))


Dim cmd As SqlCommand = New SqlCommand("list_users", conn)
cmd.CommandType = CommandType.StoredProcedure
conn.Open()

Dim dr As SqlDataReader

dr = cmd.ExecuteReader

ListUsers = dr

dr.Close()
conn.Close()

End Function
End Module


I then want to call this function from my webform. So I'm using the following

Dim dr As SqlClient.SqlDataReader

dr = Timetracker.SQLProcs.ListUsers()

Do While dr.Read
Label1.Text &= dr("first_name") & " " & dr("last_name") & ", "
Loop

dr.Close()


But it's not working. I want to have a module that contains all my sprocs and be able to call them from the individual webpages.

What am I doing wrong?

Faculty member writes:

"I meant to delete just one assignment, doing which was giving me difficulty.

I deleted a whole category by accident which had most of my daily grades in it for a course with quite a few of them. I was negligent in backing them up, so I cannot restore them. I have an XLS file from the midterm, but am missing about 6 grades after that.

Is there any way to recover the grades I had in the deleted category. It has been a couple of days since I entered any new grades. HELP!"

My current backup strategy is to do a full backup 5 pm, differentials every 2 hours, logs every 30 min, all so they arenot simultaneous. Backing these all to same backup device via three different jobs.

Then the server is backed up to tape shortly after the 5 pm full backup.

Obviously, I can't restore from the backup for this situation because it would hurt other data.

But - is there a way I can take last night's backup from tape and restore it to a different database than our production database? (Such a database doesn't at this time exist. Would I detach, copy over the files, and then reattach on prod and attach on the devl side, and then restore from the backup device to the devl copy?)

I've never had to perform this kind of rescue and am wondering if my backup strategy is flawed since it isn't immediately evident how I can easily do this.

I needed a similar thing from our Oracle DBA yesterday, and he went to tape, copied out a table and put it on the Oracle database under a different owner, and I easily fixed the few records that I had botched.

That's exactly what I need to do now with MS SQL 2000.

As the faculty dude said, "HELP!"

And Thanks.

Retrieving Data From .MDF???

Jun 26, 2006

Dear fellows,

Up to the moment I've got enough knowledge for read data stored into .LDF files by dbcc log and so on. It's very useful and interesting. Now, I wonder how to retrieve the same information but on MDF files.

At first, I want to make sure that is not possible by mean of traditional methods (dbcc or something like that) I suppose so but I'd like to hear opinions regarding that.

Thanks in advance for any idea, though or further information.

Retrieving PK To Insert Into Another Table

Mar 7, 2006

The query below should be inserting unique records in the PropertyItem table which only has propertyitem, propertyid, and itemid columns, all of which are PK's in other tables. I'm not doing the insert correctly b/c it's inserting 72 records instead of 24. I really just want to automatically insert the values once I've inserted in the other tables but I'm not sure how. Maybe On Update Cascade?


--PROPERTYITEM
INSERT INTO [USCONDEX_Production].[dbo].[propertyItem]( [propertyId], [ItemId])
SELECT Property.propertyId, ITEM.ItemID
FROM ITEM RIGHT OUTER JOIN
miamiherald ON ITEM.StartDate = miamiherald.FirstInsertDate AND ITEM.Price = miamiherald.PropertyPrice AND ITEM.Classified = convert(int,miamiherald.AdNumber) LEFT OUTER JOIN
Property ON property.adprintid = miamiherald.adprintid
WHERE validAD=1

Design Question Regarding Junction Tables

Jan 18, 2008

I'm designing a database with 3 tables called Function, Test andScene.A Function has multiple Tests, but a Test has only one Function. Amany to many relationship exists between Test and Scene therefore Ineed a junction table between these two tables - giving 4 tables intotal. The Test table would store a foreign key, the primary key ofthe Function table.There is a problem with design though and that is that Functions andScenes are actually defined before the Test is defined. Therefore itshould be possible to create a Function and add to id its Scenes,before Tests have been defined. In other words, Scenes are as much apart of a Function as they are of Tests. Tests are in fact only ofrelavence to testers. Anyway, to satisfy this scenario, a Junction boxis also needed beween Function and Scene. This creates a loop betweenall tables.Is this a good approach? Any other suggestions or advice on thematter? Any advice regarding data integrity?Thanks,Barry

Retrieving Sorted Data

Jul 18, 2005

I have four tables that need to be loaded into an ASP.NET application. They need to be loaded together into one result set and sorted. Is it possible to load four tables together and sort them using an SQL statement?

To clarify, say I have the following data:

Table1: Anglesey, Cardiff, Ceredigion
Table2: London, Dorset, Lancashire
Table3: Antrim, Armagh
Table4: Glasgow, Berwick, Edinburgh

I'd want the data retrieved from all four tables and sorted so that the data retrieved would be:

Anglesey, Antrim, Armagh, Berwick, Cardiff, Ceredigion, Dorset, Edinburgh, Glasgow, Lancashire, London

I am aware of and am using the SELECT ... ORDER BY feature of MSSQL in my present ASP.NET application to retrieve from single database tables. I'm using merged datasets and a sort method to solve the above problem at the moment.

Using COALESCE And Retrieving Data

May 16, 2012

I'm preparing a report that will display provider number, provider name, and a single field that will show all the counties that specific provider serves. I realize from researching the coalesce posts that this can be done. However, when I try to retrieve data in the same select statement as my coalesce, I get the error: "A SELECT statement that assigns a value to a variable must not be combined with data-retrieval operations."The listing of the counties must be specific to the provider, so my original code was:

DECLARE @Counties varchar(1000)
SET @Counties = ''
SELECT a.PROV_ID, a.PROV_NAME,
@Counties=coalesce(@Counties,'') + b.COUNTY + ','
from ECBH.dbo.tbl_PROVIDERS a inner join ECBH.dbo.tbl_Provider_Serv_Regions c
on a.PROV_ID = c.PROV_ID
inner join ECBH.dbo.tbl_Regions b
on b.REGION_ID = c.REGION_ID
where c.PROV_ID = a.PROV_ID
and a.MASTER = 1

I thought about creating a table to hold the coalesced values (need to coalesce two other fields as well), but wouldn't an insert to a table fail for the same reason?The counties table does not relate to the provider table, but does relate to a provider_county table (which in turn relates to the provider table).

Need Help With Retrieving Deleted Data

Mar 4, 2008

Hello,

Thank you for reading this. I am faced with a problem where there is no storage of deleted or updated information in an OLTP DB. I am mostly concerned about retrieving the deleted data from a table when an update occurs so as to make the deleted data show as an error. Is there a way to retrieve these kind of data from a DB, if so how? Can these data be retrieved by dates? Also how much time do you have before the data can no longer be retrieved? Assuming that the data can be retrieved.

I know the good stuff about datawarehousing but unfortunately we have no DW. Any help will be greatly appreciated.
