Table Design/structure Help Please...
Sep 19, 2006
Hi all
I am developing a site for a client but unfortunately
I havn't much of a clue regarding db/table design.
Scenario:
The client intends to sell window blinds over the internet.
The site has been developed using Asp.Net2 and C# with Server 2005.
I need to develop a price lookup control that has access to 4 parameters:
ManufacturerID (from existing table Products.manufacturerID)
PriceBandID (from existing table Products.PriceBandID)
Width (input by the user)
Drop (input by the user)
The idea being upon button click, the correct price is returned based on those parameters.
The price structure has been given to me in the form of Excel files.
There are around 20 different manufacturers
each with a 7 band (A - G) price matrix.
My question is what would be the most efficient way to represtent
this pricing structure under the current environment?
Will I really need 20 * 7 tables?
Any help, info, advice, pointers, links or comments would be most welcome!
Thanks for your time.

ok i have a design question and since I am not a db designer I hope somebody can give me some insight into this...
I have an app that uses a treeview control to display a hierarchy of a machine assembly. Currently it only goes two levels deep (top level and a single subcomponent.
WHat I would like to do is enable my users to add n-deep levels to the top level machine. The problem with that is that I can't think of a way to store this in a DB and how the table(s) structure would look like.
It seems like this would be a classic problem in DB design, but that is where I lack knowledge so any help will be greatly appreciated
Thanx

Hello everyone,I have a webcontrol that uses database-structures alot, it uses the system tables in SQL to read column information from tables. To ease the load of the SQL server I have a property that stores this information in a cache and everything works fine.I am doing some research to find if there are anyway to get information from the SQL server that the structure from a table has changed.I want to know if a column or table has changed any values, like datatype, name, properties, etc.Any suggestions out there ?!

Hello friends,
I am new to the SQL Server 2005 development.
From last 1 week or so, i have been facing very strange problem with my sql server 2005s database
which is configured and set on the hosting web server. Right now for managing my sql server 2005 database,
i am using an web based Control Panel developed by my hosting company.
Problem i am facing is that, whenever i try to modify (i.e. add new columns) tables in the database,
it gives me error saying that,
"There is already an object named 'PK_xxx_Temp' in the database. Could not create constraint. See previous errors.
Source: .Net SqlClient Data Provider".
where xxx is the table name.
I have done quite a bit research on the problem and have also searched on the net for solution but still
the problem persist.
Thanks in advance. Any help will be appreciated.

we have a table in our ERP database and we copy data from this table into another "stage" table on a nightly basis. is there a way to dynamically alter the schema of the stage table when the source table's structure is changed? in other words, if a new column is added to the source table, i would like to add the column to the stage table during the nightly refresh.

Below is my table structure. And I am inserting data from other temp table.
CREATE TABLE #revf (
[Cusip] [VARCHAR](50) NULL, [sponfID] [VARCHAR](max) NULL, GroupSeries [VARCHAR](max) NULL, [tran] [VARCHAR](max) NULL, [AddDate] [VARCHAR](max) NULL, [SetDate] [VARCHAR](max) NULL, [PoolNumber] [VARCHAR](max) NULL, [Aggregate] [VARCHAR](max) NULL, [Price] [VARCHAR](max) NULL, [NetAmount] [VARCHAR](max) NULL,
[Code] ....
Now in a next step I am deleting the records from #revf table. Please see the delete code below
DELETE
FROM #revf
WHERE fi_gnmaid IN (
SELECT DISTINCT r2.fi_gnmaid
FROM #revf r1, #revf r2
[Code] ...
I don't want to create this #rev table so that i can avoid the delete statement. But data should not affect. Can i rewrite the above as below:
SELECT [Cusip], [sponfID], GroupSeries, [tran], [AddDate], [SetDate], [PoolNumber], [Aggregate], [Price], [NetAmount], [Interest],
[Coupon], [TradeDate], [ReversalDate], [Description], [ImportDate], MAX([fi_gnmaid]) AS Fi_GNMAID, accounttype, [IgnoreFlag], [IgnoreReason], IncludeReversals, DatasetID, [DeloitteTaxComments], [ReconciliationID],
[Code] ....
If my above statement is wrong . Where i can improve here? And actually i am getting 4 rows difference.

2) I need to create hardware using labour and materials.
3) I need to be able to include some hardware in some products.
4) Some materials in the product are made of a culmination of materials. E.G., Concrete is made of sand, stone, and cement.
Any suggestions?

I'm new in creating tables. and I was asked to create table(s) to capture information using SQL server 2005 (express edition)
please read below and share your thoughts and opinions o what's the efficient and best way to structure the tables.
I need to capture user's input daily and every hour, text can be from 20-100 characters, and my company is expecting to have 50,000+users in the future...Also the hrs's text can be stored for max 120 days, after that data would be deleted from the table(s)
An example is put all together, (not sure if it is the right and efficient way)
An example is put all together, (not sure if it is the rigth and effectient way) and if database would support that.. and if it will be fast enougth to search for data
(table structure) - (example with 3 users)
userId | timestap | message
1 12/12/2007 10:00 some message
1 12/12/2007 11:00 some message
1 12/12/2007 12:00 some message
1 12/12/2007 13:00 some message
1 12/12/2007 14:00 some message
2 12/12/2007 10:00 some message
2 12/12/2007 11:00 some message
3 12/12/2007 12:00 some message
3 12/12/2007 13:00 some message

Hi,
I have one field "Status" with 15 different types of values. Like 1, 2, 3, 4 .. 15.
Now this Status field contains the values like this:
Id Status
1 1,2
2 3
3 1,2,3
4 13,15
What is the best way to organize this information in SQLServer table?
My idea is Create one table with the following volumns: ID, Status1, Status2, Status3, ... Status14, Status15.
Now the above data look like this:
Id Status1 Status2 Status3 ... Status13 Status14 Status15
1 1 1 0 0 0 0
2 0 0 1 0 0 0
3 1 1 1
4 0 0 0 1 0 1
So, In future If they add new column they can easily add column like status16.
And status table look like this
Status
StatusID Description
1 a
2 b
..
15
Thanks in advance

All,On my aspx page i have 2 sets of checkboxlists, each with a number of items and i am storing that info in my db. currently i have my table set up this way: InfoID--PK autoUserID-intCheckBoxList1ID-intCheckBoxList2ID-int So a user can select more than 1 item in each checkbox, so this table will contain multiple user-ids and each id from the respective checkboxes. My question is, is there a better way to store this data? I hope this is clear, any input would be greatly appreciated.Thank you.

Hi,I have a table for storing my picture albums here it is:CREATE TABLE [UserAlbum] ( [ID] [int] IDENTITY (1, 1) NOT NULL , [UserID] [int] default(0) , [AlbumName] [nvarchar] (100) NULL , [Audience] [int] default(0) , [Date_added] [smalldatetime] NULL , CONSTRAINT PK_CmmNet_userAlbum_ID PRIMARY KEY CLUSTERED ( ID )) ON [PRIMARY]GO
it has a field called "audience" as the name defines i want to choose who will see my albumsit is integer and as follows:0 value=everyone1=friends only2=private
as i started to write a query for it i came into this problem: for exampleif i write SELECT * FROM UserAlbum where audience=1 then only friends can see the infowhat happens to everyone with value of 0?when i set it to 0, friends should also be able to see the info because it is set for everybody
i noticed i should use "in cluase" like thisSELECT * FROM UserAlbum where audience in ('0','1') > so in this way both everyone and also friends can see the info
or maybe i should add 3 different fields for private,public,friends
it seems to be simple but at the same time harddoes anyone have a suggestion?

Hi i have a student table and also an societies table, and a student can belong to as many societies as possible, for example student John Taylor belongs to the Football society, rugby societey and dance society, where as student Jim Jenkins belongs to the Football society, rugby society, arts society and graphics society.
My tables so far look like this;
STUDENTS; student_id, student_name
SOCIETIES; society_id, society_name
My question is how can i make the scenario above reflect in my table structure, would i need to create another table, if so what fields or columns should i place in this new table, thank you.

I'm a VB.net programmer working in an environment that doesn't have a true sql db administrator. We have a situation where we're thinking about adding a new database (db2) with the same Tables used in an existing database (db1). We were hoping to avoid this, but circumstances are forcing us to think about it. Are there any sql tools out there to maintain a dual-db like this? What are the main disadvantages to this?

Hi,
In SQL Server, Is there any DDL available to copy a table structure alone and not the data,
I believe 'SELECT * into new_table from table1' will copy both structure and data as well.
Please advice,
