Now, the tabels above are a sitework price list for an estimating package. The tbSitworkCostTypes table is used to trace the value of the particular item back to an account after the item is added to a takeoff. My questions are:
1) How should I tie each items variable (Material, Labour, Travel, Boarding) to its appropriate cost type?
2) Should I divide the table tbSiteworkPriceList above into 2 tables as shown below?
This seems to be a little better in the point of view that each item variable is linked to the appropriate cost item by joining the tables tbSiteworkCostItems to tbSiteworkCostTypes. They have to be linked because after the takeoff is generated, the dollar values have to be imported into an accounting system where the account code and cost type code are determined by the "CostTypeID". Any thoughts?
Hello,Consider I have a String:Dim MyString As String = "Hello"or an Integer:Dim MyInteger As Integer = 100or a class which its properties:Dim MyClass As New MyCustomClass MyClass.Property1 = "Hello" MyClass.Property2 = Unit.Pixel(100) MyClass.Property3 = 100Or even a control:Dim MyLabel As Label MyLabel.Id = "MyLabel" MyLabel.CssClass = "MyLabelCssClass" Is there a way to save a String, an Integer, a Boolean, a Class, a Control in an SQL database?Something like: Define something (Integer, String, Class, Control, etc) Save in SQL 2005 Database Later in code Retrive from database given its IDIs this possible?How should I do this?What type of SQL 2005 table field should be used to store the information?Thanks,Miguel
Hi All Professionals Programmers, I would like to ask a question that is very important for me. The question is how can i create a flexible data base in which i m able to create the inner levels as much as i can. Like i have a table building, then i have another child table floor, then the floor become parent and i have its child rooms, then the rooms become parent and i have its child floor tiles etc. you can see i am going to inner dept, so i need a flexible database because its very costly and intimadting to change the database and every time create a new table and relationships. Hope you have understood what i am going to say and need advice of professional and expert user to resolve it. Any concise quality material like articles, white paper etc will also be suitable for me. Thanks in Advance
I am thinking of doing a fake PC company site for my ASP project. so what they will have is a chat, products with reviews, and users can have "Buddies".So my DB so far (Tables):ProductPC - ID, Processor, RAM, HDD, Graphics, LCD ...ProductHardware - ID, Title (Like "Intel C2D E6600"), Description, Price, Rating (0-5 stars, so integer), Category (CPU, HDD, Graphics)ProductSoftware - ID, Title (eg. "Adobe CS3"), Description, Price, Rating, Category (eg. Design, Programming)Reviews - ID, ProductID, Title, Content, DateChat - ID, TopicID, Title, Content, DateUsers - ID, Username, Password,The problem, how do i connect Reviews to the products since they are from diff tables.How do i get the "buddy" system workingChat i think its not as simple as thatBut i just need a simple ASP project, so no need to get too complex, but i still hope to learn as much.
Have an interesting issue in a database I'm trying to design and I'm trying to find a better way to setup the structure, if there is one. Going to generic example of my issue.
StudentList --- This table is the list of all College Students(with Primary Key of StudentID) MajorsList --- This is a table listing all of the majors available at the College (PK of MajorID) CourseList --- This is the list of all of the courses at the school (PK of ClassID)
This college allows students to take 1 or more majors, with the number of majors unknown. -- Any number of students can take the same majors or different majors. -- -- (aka 1 StudentID -> 1+ Majors & 1 Major -> 1+ StudentID's) The majors all have different numbers of courses in them. -- Many of the majors can have the same, or different courses in their lists. -- -- (aka 1 Major -> 1+ Courses & 1 Course -> 1+ Majors)
I'm looking to see if their is a better way of tieing together the Students -> Majors and Majors -> Courses. If done properlly, a single select and a few joins should bring up every class a student is taking for all their majors, or any other relationship to any of the three main tables primary keys.
Currently, to tie the three tables together, I have made two Interrum tables: -- StudentMajors - - With only two columns -- -- StudentID (ForeignKey tied to PrimaryKey StudentID in StudentList) -- -- MajorID (FK tied to PrimaryKey MajorID in MajorList) and -- MajorCourses - - with only two columns
-- -- MajorID (FK tied to PrimaryKey MajorID in MajorList) -- -- CourseID (FK tied to PrimaryKey CourseID in CourseList)
These tables give clear and definate ties between the tables, but my worry is that there is no primary key for these two tables, and no column in the tables is elledgeable for becoming PK, because, in this example the StudentMajors table can lis tthe studentID multiple times, each with a different MajorID. Sames goes with MajorCourses.
Is there a better structure method for reaching this same goal?
Additional, I don't know how to do a contraint that should be in place of: -- In StudentMajors, for each value of studentID, there can be no duplicate values on MajorID -- -- (same in MajorCourses tables in relations to classid's) Any advice on how to do this constraint?
I would like to create a database that keeps track of our companies subject matter experts. I have roughed out some of the tables. I would appreciate any feedback on if this is the right approach and if there might be any issues when I start writting a front-end (probably VB 2005).
What makes this interesting (at least for me) is that a subject has an owner and at least 1 "expert", possibly up to 3. Here is what I am thinking for tables:
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.
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.
ok - I have to allow my user to enter in from date - to date (multiple date selections) and these dates will be marked as holiday.. user will also be able to choose a date selection (like march 2-march 5)that was added and remove it from being marked as holiday or add new date selections.
now I need to be able to based on a date lookup whether it is a holiday or not.
what's the best way to set up the table? should I set it up with fromdates = todates or a table with each individual date and then mark it.

hello, i started making my database some time ago, and therewith i maked some relations between my tables at the beginning, at Tables, at the UserId row, i had uniqueidentifier. and because i had some difficulties when trying to get the username who corresponds with that uniqueidentifiers i've discarded that and replacing the uniqueidentifier with varchar(255) where i am writing dirrectcly User.Identity.Name. Because of that, i had to delete some of the tables relations, because i can make relations only by unique variables (witch in fact are unique but database can't know that) What i should do now? remake the tables with UserId as uniqueidentifer or i should let it so without no relations between them? (witch i don't think is good) thanks

1) I need to create a product using labour and materials. 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?
So far I have :

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 3 12/12/2007 14:00 some message ...etc..
Hi,I am new to XML and need a structure of table in XML format, which needsto be created as a table in another server.The Source and destinationservers are SQL Server 2000. Could anyone help me on this.Balaji.S.--Posted via http://dbforums.com
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
Hi, I have the following two tables in MS SQL 2000 1.Products: ProdID intProName char(10) 2.Orders: OrderID intProdID intOrderDate DateTimeQuantity int I want to join these two tables to form the following result format: _________Prod1__Prod2__Prod3__Prod421/01/07__1______0_______1_____0___22/01/07__5______1_______2_____3___23/01/07__8______0_______1_____2___24/01/07__3______3_______4_____3___25/01/07__2______0_______1_____4___26/01/07__1______2_______6_____2___ So the first row would have the product name, Left hand column has the order date and then the sum of all the orders within Any pointers on how to achive this would be great.
I've been assigned to do the data access layer for an existing SQL database created by someone else. Amazingly enough, the primary table, the one containing all of the records that are central to the db and the whole project, has over 3000 entries and no unique identifer (autonumbered ID) column. The data in all of the other columns is repetitious so none of them can be used as a primary key. I have added a column called TaskAssignmentID, designated as an int data type. The goal is to somehow autofill this column with sequential numbers and then designate that column as the primary key. (don't you just love fixing other people's mistakes?) Any suggestions/examples on how to accomplish this the easiest, most efficient way?
For reference purposes, the table is called tbl_MCHS and the newly created column is called TaskAssignmentID. The data type of the column can be changed, if that would make it easier.
Tools available include Visual Studio 2005 (very familiar) and SQL Server 2005's SQL Server Management Studio (less familiar).
Things I am restricted from doing include blowing away the table and starting over or strangling the previous developer (I asked about both). :-)
Any and all suggestions, steps, or examples will be appreciated.
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?
