Hi, not sure if this is the right forum for this question.
I am creating relational tables for the first time in sql server express. I will have an orderItems table and an orders table. the MenuItems table is the problem. It is a catalogue of books. There will be about ten columns. all are unique to each book. i.e isbn number, title, author, publisher etc. but ten columns seems to be quite cumbersome. it may be easier to break the table down into two tables (i.e. primary details and secondary details perhaps) However to populate the table in the first place it would be easier to have it as one table instead of opening and closing 2 tables Adding the odd book to the two tables in the future would not be a problem. so the question is can i create a table and then brak it into two relational tables afterwards. If so how do i do this. this is my foirst go at relational tables and i am still trying to get a handle on visualising them. If my logic is up the wall please let me know....
hello, I am beginner for asp.net and sql server. I used Sql server manegement studio full version and I exported my aspnetdb which was created by VS2005 to my host sql server. I have a question: relational tables are not relational no longer. I noticed that when I created database diagram. what is wrong by exporting? thanks for your helps...
I need help with database design. I am doing a bowling league program. 1. each bowling center has 1 or more leagues 2. each league has 2 or more teams 3. each team has 2 or more bowlers 4. each week each team bowls 3 games 5. summer leagues last ~13 weeks winter leagues last ~36 weeks
Tables I have + is primary key FK is foreign key BowlingCenter + CenterID ......
League + LeagueID FK CenterID .......
Team + TeamID FK LeagueID
Bowler + BowlerID FK TeamID
Here I am lost. How do I do the 3 games a week for 13 or 36 weeks AND associate the 3 games each week with each bowler?
I understand the basics for doing an insert. Their seems to be many ways of achieving the same thing in .net. I have used the tableadpaters and sqlcommand functionality to achieve this. My one question is how foregin keys should be created in associated tables. EG so if i create a new record entry in one table and the primary key for that entry is a foreign key in another table, do I need to call 2 table adapters, or run 2 sqlcommands(taking the primary key from the first traction and use this in the next transaction)?
Any help or direction for some good tutorials on this would be much appreciated.
Ok, I have a page on my website where we can add products to our database. We are a music store, and most products have different versions or colors. I've created 2 tables, Products and Subproducts. The products table may hold info like Fender Stratocaster, and the subproducts would hold colors (Blue, Sunburst, etc). The subproducts table has an integer field called MainProductID, which is linked to the mainproducts table field RecordID. So far the page uses a wizard where if first creates the main product using an sql datasource. After the data has been added to the main products table, my page gives you the opportunity to add different sub products. The problem I am having is actually feeding in the RecordID from the main products table to my insert parameter on the sub products data source. This is what I have tried so far: There is a formview on the page that is bound to the main products table, after the entry is created I can physically see the info on my screen, so I know the data is there at my disposal SubProductsDataSource.InsertParameters.Add("@MainProductID", Formview1.datakey.item("RecordID"))SubProductsDataSource.Insert()Using this adds the data to the table, but the MainProductID is nullalso is there a cheap little way to refresh a page, because when I upload the product images I have it go to the next step where you are supposed to be able to see the images you uploaded, I don't see them which makes me think that the page is loading faster than the images are uploading. Thanks
I am trying to insert data into 2 different tables. I am using dataadapter and dataset.
Protected Sub SubmitButton_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles SubmitButton.Click Call ConnectionString()
Dim insertSQL As New SqlCommand() insertSQL.Connection = sqlConn insertSQL.CommandText = "SELECT location.CountryName, location.CityName, location.BuildingName, location.FloorID, rooms.name, rooms.FloorID AS Expr1 FROM location INNER JOIN floors ON location.FloorID = floors.id INNER JOIN rooms ON floors.id = rooms.FloorID"
Dim ds As New DataSet() Dim da As New SqlDataAdapter()
da.SelectCommand = insertSQL Dim scb As New SqlCommandBuilder(da)
Try da.Fill(ds) Dim ndr = ds.Tables("location").NewRow Dim ndr2 = ds.Tables("rooms").NewRow
I have two tables with data that I need to get and display in a combobox. What I want to do is have the parent table listed in the combobox with all of its children indented. Sorted by parent then by child.
This SQL seems to be more complex than I have done previously
I can get all of the records from both tables easily:
Code: SELECT strName, ID FROM tblParents as pp INNER JOIN tblChildren as cc ON cc.pID = pp.uiGUID UNION (SELECT strName FROM tblChildren as c INNER JOIN tblParents as p ON c.pID = p.ID)
However, this simply returns a list that is not ordered in any fashion. I'd like to have all of the parent's children shown under the parent name (there is only 1 parent per child and multiple children per parent)
I'm shredding the below xml into relational tables. Each element of the xml has it's own table and there is a foreign key to join the tables, you can see this in the below picture. The process I follow is each relational table I always bring the nesecary xml and store it in the table and when shredding I always look at the parent table.So for example when processing the seat table, I use seat xml from the parent route table, also taking the ROUTEID from the route table. The reason I do this is all about taking the id from the previous step to create the relationships between the tables. without taking the xml down to the tables?The problem with this approach is I have xml stored in most tables and the tables are becoming very large.
Hi all, I am trying to create a diagram for our database, during the creating, I create some of the relationships which were not there(basically our original database is not relational database, that's why I am doing it) So sometimes I have to chage data type in order to create a relationship for the coloumns in different tables. i.e. change char(16) to varchar(7) (I checked the field that make sure all the data in this field is <= 7 characters)
But when I saved the diagram, there is an error message that state: Errors were encountered during the save process. Some of your database objects are not saved on your diagram.
'agent' table saved successfully 'VisitUSA' table - Unable to create relationship 'FK_VisitUSA_agent'. ODBC error: [Microsoft][ODBC SQL Server Driver][SQL Server]ALTER TABLE statement conflicted with COLUMN FOREIGN KEY constraint 'FK_VisitUSA_agent'. The conflict occurred in database 'CMC', table 'agent', column 'AgentCode'.
What does that mean? is it caused by some of the agentcode data in VisitUSA table which is not in agent table? Thanks! Betty
I am trying to build something similar to www.alienware.com where it lets you build your own computer. I was wondering if some one could help me design sturcture to do it on my own. I am zero in DB and know little asp. I am trying to do it for my own site.

Friends, Who is responsible for the Design of Database? System Analyst, DBA, Databse Designer, Project Leader? Coz I am working as a System Analyst, but now desgining the Databse for the ERP package which I feel is another man's work. Confussed. Plz help me.
Dear Friends,I'm a junior DBA, I've to prepare an online examination. for this, I've three categories. a)beginer level b)intermediate level c)expert level
again here subjects are 6. like sqlserver,oracle,c#,vb.net,html,javascript. in these subjects, i've to select these three types of questions. now how can i design for this requirement? shall i create three tables for beginer, intermediate,expert or shall i create 6 tables and write according that?
I am new to sql server. Currently i am using sql server 2000. i have created two tables course and student , with course_id and stu_id , as primary key of the respective tables. Now i am trying to relate them through the diagram , in order to create a relationship between the two. When i try to draw a relationship between stu_id and course_id , i get the following error error: Unable to create relationship 'FK_stud_course'. ODBC error: [Microsoft][ODBC SQL Server Driver][SQL Server]ALTER TABLE statement conflicted with COLUMN FOREIGN KEY constraint 'FK_stud_course'. The conflict occurred in database 'student', table 'course', column 'course_id'.
Im creating a sample database for purposes of keeping track of employee's jobs + billing codes for that job. currently they just use an excel spreadsheet to keep track of billing.
Question 1:
What would be the easiest way for the manager to enter billing codes? Billing codes are numbers like 956, 958, 805 and they co-relate to prices for each billing code.
1. I want the manager to enter the billing code and have the sql database find out how much that code is and add them up daily. This would prevent the manager from having to input prices and billing codes, and extra step.
Any links on the above topic would be helpful. I'm not looking for anyone to spoon feed me code just point me in the right direction. Im relatively new to sql having only a class of sql @ ITT.
Heres the way I have the db tables laid out currently.

I am having problems populating a target and then using that populated target as a source for subsequent targets.
Hey,I have a fairly large table for my keeping my information about users. My question is, would it be better to separate it, for example, create another table that has all the personal information (like city, street, etc)and have it related to my other table where more of the data-ish information is kept? Thanks,Sixten
Hi all, Does anyone know how I can design the database schema. I mean what tools can be used to the design the database and view the table relationships, etc. TIA.
One interviewer has asked me the following question: What are the things that you consider while designing database? I have told about integrity constraints, and normal forms. but he has added 15 more concepts like 1. indexers 2. Table columns 3. Table rows 4. search facilities 6....... Can any one give full Idea on this question? Thanking you Ashok kumar.
My current project requires me to convert a mysql based software to a more generic one. I started by designing separate db class files and separated the lower level connection queries from the business logic. By doing this, I now have mssql.class, mysql.class, sqllite.class etc..
But am not sure how to handle sql functions in queries. For instance, one of my queries need the use of a date function to add minutes to a db field.
In mysql, I accomplish this using
dbfield+interval '$arg' minute between date1 and date1
But in mssql I cannot use this type of query. It seems I'll have to use date_add() function. How do I handle this situation?
With my next application, I'm thinking about establishing a new security paradigm for my programs, with respect to SQL Server.
In all my previous applications, connections are established using SQL Server authentication. So, all my users may log-in under a single log-in, mapping to a single user in a database. My application then has to use its own security arrangement to determine who has access to what forms within the application. There are three major problems with this design: 1) the user name and password to connect to the SQL server have to be resident as strings somewhere in the application code (or ancillary files), 2) everyone connecting to the SQL Server "looks" the same, and 3) you have to give the broadest rights to everyone with the same login and then pare those rights down within the application itself.
By implementing multiple SQL Server Authentication logins I can mitigate problems 2) and 3), but the only way to eliminate problem 1) is to move to Windows Authentication.
Windows Authentication would allow me to resolve all three design constraints, but there is one problem that I see coming as a result.
If I use Windows Authentication, each user must have an independent login to the SQL Server. If I have an application that may have 4,000 to 6,000 users, does that means I have to have 4,000 to 6,000 logins set up on SQL Server?
Is that true?
I could, of course, generate a script to build all 4,000 to 6,000 users, but I am concerned about this.
Is this a "normal" arrangement that SQL Server has no problem-with?
I'm currently developing an ASP.NET site with SQL Server 2005 Standard and I'd like to ask a question about the future of the database. It needs to have continuity and performance. I'm thinking about doing replication or mirroring for continuity and table partitioning for performance. I admit I've never done any of those before and I'll learn about them but they're not needed at this time. The question is, I'm currently designing the database and do I have to anything for consideration for those things I'm thinking of implementing later? For example, I'm using Identity in my tables but I've heard about identity crisis using replication with identity columns, therefore I'm thinking of using Guid's but now I fear the Guid column index itself will be the slowdown factor in the first place.
Any suggestions to consider? I'd appreciate any opinions.
Hi i am designing a database. It will be used by field guys who will insert new records and will replicate at the end of the day with a central database using merge replication. Can anyone tell me if I am choosing wisely or not with the following 3 points: 1. i am going to use a uniqueidentifier value in a column (using newid()) for the merge replication. (I don't care that it's an ugly value as i never plan to look at it.
2. I am using an identity column (INT)to create a unique value within the table
3. I want to create a unique column comprising of data from other columns (e.g. date+identity+salesrep) This gives me an intelligent candidate for a primary key. But I think i have to create this with an instead of trigger (is that right)
1.update on this derived table daily (how/what should I do - with triggers/jobs against the original tables?) 2.create a view that would show: - by years the percentage of sold products - quarterly percentage of new customers / rebuyers / etc. - ... 3. Thinking of making a cube in BIDS (with dimensions / measures)
I want to design a login named "JobAdmin" who can add/modify/delete any SQL Agent Jobs but can't access my "db1" database. The jobs would execute some stored procedures in db1, and it could be a user "db1dbo" with db_owner role in db1 to execute the stored procedures.
How could I let JobAdmin impersonate db1dbo to run these jobs? Thanks in advance.
i have created a report which contains a table(header,group header , details)... when i get a copy in pdf format i got more than 20 pages...the issue is the table top border is not displayed in all pages except first page...
for example
if i have two pages ..
first page top border is always displayed properly ..second page top border is not displayed properly.. i think this issue because of alignment , i have tried a lot of scenarios nothing works ...
I am asking something very basic and theoretical, here.
Are there any design tools available in the market for designing SSIS packages? By "design tools" I mean tools which enable us to "plan" or "design" the architecture of a SSIS Solution that will be implemented later, using SSIS, of course.
We have several design tools available for designing a Web Application solution, for example. Similarly do we have something for SSIS?
Are there any design approaches, best practices and/or design techniques published for designing a SSIS solution?
Please note that I am not talking about the SSIS Designer or the BIDS. I am talking about a tool/approach for designing the SSIS solution which can be delivered as a project artifact before the actual coding phase starts?
Well, I have tried to express myself as best as I could. If someone can help me with this, it will be really great!
