Is This Table Design Correct?

Mar 22, 2004

Hey Everyone,

Just had a quick question for you . I have these 3 tables that are related in some way - below are the structures. I know the structures are correct and they work fine. However, I am using Visio Enterprise Architect to design these tables and when I try to generate the code, I get an error saying that it does not like the table with 2 fields as the primary key. And I just wanted to get feedback to find out whether I am correct or Visio is.

Table: Orders

Columns:

OrderID int PK

Name varchar(100)

Phone varchar(20)

Table: Products

Columns:

ProductID int PK

Name varchar(100)

Table: OrderLineItems

Columns:

OrderID int PK

ProductID int PK

Price money

Thanks for any feedback.

I would like to create a table called product. My objective is to get list of packages available for each product in data grid view column while selecting each product. Each product may have different packages type (eg:- Nos, CTN, OTR etc). Some product may have two packages and some for 3 packages etc. Quantity in each packages also may be differ ( for eg:- for some CTN may contain 12 nos or in other case 8 nos etc). Prices for each packages also will be different that also need to show. How to design the table..

Product name :
Nestle milk |
Rainbow milk
packages :
CTN,OTR, NOs |

CTN, NOs
Price:
50,20,5 |
40,6

Getting Correct Data From A Table

Dec 20, 2004

Hey,

I have a temp table with a column of all the same number. When I run my select statement I need it to bring back all the other data and just the single instance of the column with all the same numbers. How would I do this in my select statement?

For example, here is my table:

Here1One
There1Two
Up1Three
Down1Four
Back1Five

I need to bring back everything from column 1 and 3, but just the single instance of 1 from column 2 since it contains all the same number. All the data is collected in a single select statement.

Any suggestions?

Thanks

How Can I Create These Table In Correct Way??

May 17, 2008

I need to create these tables..But i dont know how to create in correct way The question is in quote
...Please help me ..

quote:
Blue library has required an application to manage their works. This library organizes books with categories and sub categories. So each book belongs to a category. Books are stored with their title, author(s), edition, publication date, ISBN, and Publisher Company. Publisher Information must be stored in the separate table for data integrity. Additionally each book must have information about if it is international edition or not. Books must be searchable by their title, author and their categories.
Also, student information with their department information must be stored. Each student must have std id, name, surname, dept_id, enterance_date. And department table should have dept_id, dept_name columns.

When a student comes to library to reserve a book, the librarian should be able to reserve the requested books to the student. Each student may take at most 3 books. And each book should be returned in a month. The library manager should be able to take the list of books that are not returned on time. Also, library manager should be able to add/delete/update categories. However, other librarians should not be able to perform those tasks. Librarians should add/delete/update the books and reservations. For those functionalities, you should have two user categories that are Library Manager and library operators. Your database should support multiple operators. Unauthorized access to database should be prevented with user passwords. Each operator and Library Manager should have their own passwords. Library manager should have all privileges on library operator accounts. (i.e: retrieving a forgotten password, removing an account, adding a new operator account, etc.) User management process should be done by library manager account.

Trying To Correct Corrupt Table

Hi there!

I need to execute: ALTER DATABASE MyDB SET SINGLE_USER
which always returns Timeout Expired.

I can't execute dbcc checktable (MyTable, REPAIR_ALLOW_DATA_LOSS) until the database is in single mode.

How else can I set single-mode or can I bypass that requirement?

Thanks!

Can't Get A Subreport To Start On The Correct Page Or Table Header To Repeat On Multiple Pages

May 24, 2006

I am staring to lose my mind on all this "work-around" BS in trying to create a dynamic header.

I have a report with contains a table, whose first two lines are a header line in which I want to repeat on each page. Then I have about 20 detail rows of information related to the header. The 21st detail row is a merged cell that contains a subreport relating to the header item.

When printing to PDF, the detail rows consume about half the page and the subreport is anywere from half a page to several pages long. When the subreport is more than half a page, it skips the end of the first page and starts on the top of the next page, leaving the bottom half of the first page blank. No matter what I set the page breaking to, it continues this behavior. In addition, when the subreport data spans more than one page, my parent table's header row will not print to the next page even it the RepeatOnNewPage is set to true.

I am coding this way because I have found no good way of creating a dynamic header that will correctly and consistantly display data that has detail that spans more than one page.

Any thoughts on what I might be doing incorrect?

DB Design :: Table Partitioning Using Reference Table Data Column

Oct 7, 2015

I have a requirement of table partitioning. we have 10 years of data on a table which is 30 billion up rows on 2005 server we are upgrading it to 2014. we have to keep 7 years of data. there is no keys on table or date column. since its a huge amount of data and many users its slow down the process speed. we are thinking to do partition on 7 years for Quarterly based. but as i said there is no date column on table we have to use reference table to get date. is there a way i can do the partitioning with out adding date column on table? also does partition will make query faster?

I have think three ways to do it.
1. leave as it is.
2. 7 years partition on one server
3. 3 years partition on server1 and 4 years partition on server2 (for 4 years is snapshot better?)

Integration Services :: Mapping Correct Surrogate Keys In Fact Table After Performing SCD Type 2 On Dimension

Nov 5, 2015

I have dimension data like this

persn_key persn_id address is_active updated_date
1 10 NYC 0 2015-11-04 14:19:54.817
2 10 Chicago 1 null

and Fact table like

fact_key persn_key units_purchased
1 1 10

persn_key is the surrogate key between tables.

My question here is as the dimension has SCD type 2 on it and every time when there is a change the persn_key gets a new key value but the fact table still points to oldest key.how to update the surrogate key on fact table to the current key value? As per the requirement fact surrogate key must be pointing to current active record on the dimension.

Table Design

Apr 30, 2008

Hi, I am developing an application to a garment factory. I have a doubt in designing a table.Basic tables:Jobs, JobColors, Material, Units, Currencies ...These tables are designed with normalization rules.I got a problem at PurchaseOrderDetailsMain
table is JobMaterial. It has materialid, jobid, supplierid, description
and TypeFactor(which represents the type of order) means that the
material is ordered based on size or colors or total qty.1 for ByColor, 2 for BySize, 3 for ByQty, 4 for By Contrast colorsThe main problem at the details of the sub table.JobMaterialDetailsIf typefactor is by size, i need to store the details based on sizeex: S - 2000pcs, M - 4000pcs, L - 4000pcs, XL - 2000pcsSo I will have 4 records per each sizeIf it is by color, White - 3000pcs, Portabella - 5000pcs, Black - 2000pcs.If it is by general, Total qty 10000pcsHow
can I design this table. If I take, ColorOrSize column, it will refer
different values for diffrent typefactor. When by size, it will have
Size and when by color, it will refer colorcode.But colors are having referential integrity. So it is violated other than by color as typefactor.What is the best way to design this table?Can anybody suggest?Thanks in advance

Table Design

Aug 21, 2000

Coming from a support background and having to design my first database I have a couple of questions re- table design. Firstly I have set up several tables and included one field (of the same name) in each. This is a primary key in one table with an incremental seed. I would like this info to appear in the other tables although these can be duplicates in the other tables. How is it best to achieve this relationship. From reading it suggest FK in the relationship application but looking at other databases this seems to have been achieved by some other means. Is it more common to use stored procedures to enforce this? If so please add pointers. Secondly, I have set up a couple of master tables to act as looks ups for fields in other tables. Again how do I get this to look up the table - is it done through stored procedures or at the time of writing the front end application?? Sorry if this is all basic stuff but it is new to me.

Thanks for any help

Table Design Help

Mar 16, 2004

I'm currently developing a real estate system to manage order processing and work flow. I'm a little uncertain as to how to design the tables because an order can have N number of applicants, owners, buyers, and properties. There are cases where there are 9 different buyers and some where the number of properties exceeds 20. It seems that normalization might make the situation crazy, but I'm a touch rusty. Thanks.

Table Design ? What To Do?

Apr 16, 2004

I am developing an estimating application and at the "quantity takeoff" level, all products/equipment/sub contracting/etc.... end up on the same table because of the common elements:

Item | Quantity | Unit Price | SubTotal | Total

Now, since the unit price of a product is not determined from the same tables as the unit price of equipment rentals or sub contract work, etc...
how do I direct the attention to the appropriate table when trying to obtain the unit price or edit the unit price etc...

If my question is not clear, let me know, I will try to clarify.

------------------
DEPARTMENT_CODEint
DEPARTMENT_NAMEvarchar

In employee table I have to store two country names.
ie. employee currently working in this country
but his home country name (origin country) is another
name. In country table all countries information available.
ie. country_code and country_name.

How I can design the employee table that it get country_name from COUNTRY TABLE ?
but we can not use same country_code in two fields.

OR
otherwise I will have to create employee table like this

employee table
------------------------
EMP_ID varchar
NAME varchar
DEPARTMENT_CODEint
POSITION_CODEint
COUNTRY_CODEint
COUNTRY_NAMEvarchar

ie. during data entries direct insert the country_name in employee
table ?

I want to create separate table for separate data.
department,postion,country.

How I can use unique country_code in employee table's two
fields ?

Best Table Design

Nov 8, 2007

Hi,

I'm struggling coming up with an optimal table design for the following scenario.

I have a table in which each row is recording information about a document - author, publisher, publication, title, abstract and so forth. I also have an image table which contains information about the images which can be associated with the documents.

Each document can have on of three image types associated with it - an author photo, a publisher logo and a publication logo. There aren't actually that many different authors, publishers and publications in the database so it would be common for many documents to have the same author or the same publisher although authors sometimes write for different publications. In the current setup it's possible for a document to have more than one image of each type associated with it, which is undesirable - this needs to eliminated and we need to ensure that each document can only have one image of each type associated with it.

It'd also be a huge boon if I could get all the information about a document and it's attached images with a single database call. In the current setup, trying to do this returns multiple rows so I've ended up making two calls, one for the document and one for it's attached images.

I can see two possible ways of setting this up, neither of which appeal.

The first is to add three columns to my document table to record the image URLs which is simple but inflexible should I want to add more image types later on.

The second is to set up three new tables for author, publisher and publication and associate each of these with the document table through a key and then to the image table through another key. There's also an image type table which is going to come in to play. I'm unwilling to do this because it's going to just explode the number of tables I've got, especially if we add more image types, and play havoc with my XML schemas.

Is there another way of rationalizing this that I've missed?

Cheers,
Matt

Table Design

Jan 11, 2007

Hi,

I am trying to decide between 2 table designs. I basically have several different types of work items that need to be tracked. Each work item has their own set of statuses, some of which may be the same as other work item's statuses, some of which will be unique for that work item.

Now, should I create one status table for each work item, or would it be better to use one status table, but add a column to track which work item the status belongs to?

I'm not sure which is a better design, or perhaps there is some alternate design that is better. Any help is appreciated.

Thx.

Design Table Need Help

Sep 20, 2007

Currently I need to design database table and got stuck.

I have a project and its sub projects. A parent project and its sub projects share the same requirement.The description of the requirement will be changed every day.
For example
Project A - Do Some thing 1 on Project A [09/28/2007]
Project A-A1 - Do Some thing 1 on Project A [09/28/2007] , Do Some thing 2 on Project A [09/29/2007]

Every time the comments updated, both project A and project A-A1 should share the same update i.e select project A and its subproject will be displayed
Project A Do Some thing 1 on Project A [09/28/2007] , Do Some thing 2 on Project A [09/29/2007]
Project A-A1 Do Some thing 1 on Project A [09/28/2007] , Do Some thing 2 on Project A [09/29//2007]

When you tried to insert new sub project, the requirement will be shared with the parent project ie.
Project A - Do Some thing 1 on Project A [09/28/2007]
Project A-A1 - Do Some thing 1 on Project A [09/28/2007] , Do Some thing 2 on Project A [09/29/2007]
Project A-A2 - Do Some thing 1 on Project A [09/28/2007] , Do Some thing 2 on Project A [09/29/2007] , Do Some thing 2 on Project A-A2 [09/30/2007]

assume Project A-A1 and Project A-A2 are sub project of project A

Could anyone show me how to design the database table for those mess?

Thank you

Jan 3, 2008

Hi All,

If I have the following data that I need to put in a lookup table, what would be considered the proper create table schema for it?

G, "Group"
R, "Region"
D, "District"

Would you setup your table like this:

Level_ID Varchar(1),
Level_Desc Varchar(20)

Or would you go ahead and create like this

Level_ID Integer,
Level_Code Varchar(1),
Level_Desc Varchar(20)

Not sure which one would be the preferred method.

Thanks,

Table Design

Dec 17, 2007

I have a huge database and off lately, I have been experiencing some performance issues on some queries. Some of my tables now have over 10 million records. I noticed the performance issue was caused mainly from one table created as a work around. If I remove the column from the workaround table (but still leave the table in the query), I get the results in 1 second. However if I include a column from the workaround table, the same query takes 14 seconds (same output only an extra column) . I will appreciate any advise on a better design to get around my workaround table.

Below is my scenario

Table - Team
-------------------
Column -
TeamID (Primary Key)
TeamName

Table - Matches
---------------------------
Columns -
MatchID (Primary Key)
MatchName
Team1ID (Foreign to "TeamID" in Table "Team")
Team2ID (Foreign to "TeamID" in Table "Team")

Table - Players
----------------------
Columns -
PlayerID (Primary)
TeamID (Foreign to "TeamID" in Table "Team")
PlayerName

The above tables work very well... The tables I listed below are my cause of issue... I need to write a query to list every match with the names of players who played in it comma delimited (one row per match).

I created a table

Table - MatchPlayer
-----------------------------
Columns -
MatchPlayerID (Primary)
MatchID (Foreign to "MatchD" in Table "Match")
PlayerID (Foreign to "PlayerD" in Table "Player")

But I couldnt write a query that would list me all the players comma delimited in one row per match..

So I put a workaround

Table - MatchPlayer1
-----------------------------
Columns -
MatchPlayerID (Primary)
MatchID (Foreign to "MatchD" in Table "Match")
Team1PlayerNames (Comma Delimited values - varchar(800))
Team2PlayerNames (Comma Delimited values - varchar(800))

This allows me to easily list the player names comma delimited per match but is a very bad design. Is it possible to list the same using the table Match Player.

Thanks in advance

Table Design Of User Table.

Jun 23, 2006

We are in the early stages of developing a small project and I have a question I would like an opinion on.
When deciding how to design a table to store information on users who will be different types.
The project involves setting up webpage that allow " appointment setters" to book demos for our Sales reps. We want to keep track of how many each appointment setter books.
I have a user table with user_id, fname,lname, type. Where type represents the type of users they will be either "appointment setter" or "Sales Rep".
In the Appointment table I would like to store the Appoinment setter ID, sales rep Id, date/time appointment was booked and some other data on the appointment.
My question is how do I set up the relationship from the appointment table back to the user table.
Since each record in the appointment table will have a App Setter ID and a Sales Rep ID.
Should I just pick either the app setter id or the sales rep id as the foreign key back to the userID in the user table. Or is there another method how to handle this.
Any thoughts or articles would be greatly appreciated.
thanks,

SQL Table, Key, Field Design

Dec 5, 2007

i am putting together an application for a client of mine that involves image heavy data handling. i have a couple of possible methods in mind of how to go about this, and would like some outside opinions, especially from any of you who may have done anything similar before.
to quickly sum up the application's desired results: a photo gallery that contains four sections of job before/after photos. 1)residential 2)comercial 3) automotive and 4)specialty. when a site browser clicks a section, it will bring up a gridview of the "key" or ideal photo (one each)from several different jobs. the site browser can then click the photo, and a new page (or new control, does'nt make much difference) will come up showing all photos for that particular job.) past and current customers will create user logins to have ability to upload photos of their specific job. admin needs ability to 1)upload photos for many jobs 2)review all photos before posting them to the gallery 3) would like to give admin ability to order the photos within the gallery and within each job 4)admin needs ability to create tagline with short description either for each photo or at least for each job.
as to the design of the data, i can either store the images themselves in the database, or create tables to tag the images with various identifying data, then simple store and call the images in a directory on the server. i have code to do either. i am trying to construct a database design to handle all issues. i like the idea of storing photos in the database more, just not sure how to architect it. it would be the 4 albums, each with infinitely create-able 'job' albums within, each job album housing job photos.
i am thinking the images maybe get a table for their specific info (ID as primary key, image itself, file type, length, and a foriegn key to a job table that has jobID primary key) the job table could have a job name that user inputs, thus identifying all photos to the same job. the job table would also foriegn key to the album table id, with its four categories of residential, automotive, commercial, and specialty. does this method seem feasible? if this system seems workable, i can throw in a boolean default to false for the admin to set true to display the job photos as a whole, with admin power to delete photos on an individual basis. but i am a little stumped how he can maybe order them? maybe an int field that he can edit and just manually put the jobs in the order he wants? and then put the photos under the jobs in the order he wants as well?
it seems i have somewhat thought this out just now while writing, so it seems i have a somewhat workable solution, if awkward, but if anybody knows a simpler, or tried and true, method, please let me know
any ideas, suggestions, and help is greatly appreciated.

Table Design Question

Jan 2, 2008

Hi all
I am more of a front end UI developer but have been tasked with building a project from scratch - here is my question.
I need to store information on Cases (e.g. Helpdesk calls/Customer Complaints etc...) and then against each Case and number of Activities. This is what I have come up with:

2 Tables (Case and Activity)
