What would you all suggest a database with less number of tables and more number of columns or more number of tables with less number of columns. I am developing a web application using Visual stuio 2005 and Sql Server 2005
View 2 RepliesI am developing the Home page of a Client. Apart from various things on this home page I have a text box and search button. Having said that, I have a database in which I have almost 12 tables with varying number of columns. Now my question is,Is there anyway to search a word typed by a user in the textbox to search it in all the tables(all columns) of the database.

View 3 RepliesHow to create a table which is the combination of different columns in database tables.
I know how to make the var table using single table.
What is I have to combine multiple coolumns and create a table.
My requirement is a gridview which has a datasource which is loading from columns from multiple tables.
I have two SQL Server tables with Primary Keys (PK) and a Foreign Key (FK) linking the two tables:
1) Table "Order"
OrderID, int, PK
AddressID, int, FK
...
2) Table "Address"
AddressID, int, PK
City, nvarchar(50)
...
Then I've created an (ADO.NET) Entity Data Model out of those two tables. Now on my (ASP.NET) webpage I put a GridView with an EntityDataSource. In my GridView I want to display two columns:
OrderID City (belonging to that order and linked by the AddressID-key) How can I do that? My problem is: When I configure the Entity Data Source I can select an "EntitySetName" which can be either "Order" or "Address" but not both, nor can I select any kind of relationship. If I select "Order" as EntitySetName
then in the GridView I can add the columns
OrderID
Address
Address.AddressID
Adding the column "Address" displays empty cells. Adding "OrderID" and "Address.AddressID" displays the expected IDs. But how can I add the "City" of the related address to my GridView? Edit: Clarification:
The Entity Framework has created a class "Order" and a class "Address" corresponding to the database tables. The class "Order" has a reference to an "Address" object as a navigation property, corresponding to the 1-n relationship between Address and Order table. Basically I want to have a column in my GridView which displays Order.Address.City. I have tried to add a bound field with "Address.City" as data field to the GridView but it results in a runtime error ("no such property...").
using sql server 2005 and vb.net 2005. I am writing a console application to import a mass amount of data from a non-sql database table into a sql server database table. The destination db table (sql server) has fewer tables than the source db table so I need to map the columns. does anyone have an example of how to do this?
View 1 RepliesI have two sql tables.
- (Fields:PersonID, FirstName, LastName, Role, Department)
and
- (fields: PersonID, Unit).
I want to merge those with a single table ( Fields:PersonID, FirstName, LastName, Role, Department, Unit). How can I query to accomplish this so that same personID data go to same row ? ANY QUERY ?? (I have an idea : both export to excel and merge into a single excel file and import to SQL table but due to very long data it was truncated last time when importing so I don't want to reimport again.)
I have set up a SQL Role and denied SELECT, INSERT, UPDATE, DELETE access to a number of tables.I noticed that a user in this role can create a stored procedure containing a SELECT, INSERT, UPDATE or DELETE statement on the table that I have denied access to.How could I stop the user in the role from being able to create/alter/execute stored procedure which use the tables than I have denied access to?Also, the user in the role needs to be able to execute stored procedure on the tables which they are not denied access to.

I want to add custom columns to some tables created by ASP.NET. For example; I need to add two fields such as FirstName and LastName to the aspnet_Membership table.
I can add this directly by editing the table but;
Is this the right thing to do (I mean; extending the table directly) OR should I create a separate table and hold the extra user data, there?How can I see these custom database fields as properties in code completion? example: membershipuser.FirstName;
i have one database named as sampleDB its having more than 100 tables. this database running on production. here we have one requirement need to add companyid feild all the tables in our sampleDb. is it possible to write query to alter all the table.

I'm working on a new asp.net 4.0 resume web site. I'm starting off with SQL Server Express 2005 and using the standard security and login features given with ASPNETDB.mdf. My site will be hosted on GoDaddy.com.
Quesiton. Should the tables that will contain the information that users will be putting in like resumes, contact information and such go into ASPNETDB.mdf or should it go into a separate database.

I used to work in the IT field, but because of an accident and meds I have lost a bunch of my memory. So, I'm in need of relational database help..I've got a web site I want to put up that will sell books. I'll be using SQL server 2008. I'll be using Pay Pal's Cart, etc, so I just have to put up some buttons on the web site, but I need to track, display, etc, the books and properties about the books such as Authors, Paper back or hard cover, first edition, or something else, etc,..I have a table for books obviously, but I'm wondering if I should break out the Authors out of that table? I mean I don't see why except that if I end up with some books that have the same author then there names will be stored more than once, but I will be doing a lot more queries than inserts. I've got Customers, Book Types which is if the book is a hard cover, softcover, first edition, etc,. I will relate the Books to the Book Types of course, but again, should I have an authors table? Hope this makes sense.. I am using Visual Studio 2008 Pro, and want to do my relations there, so I thought I'd do so in the IDE if possible? I can't remember, but I thought it was possible?

I am in a situation where, I have to copy a databse with records and also want to include new columns in it?
Or can I copy a db schema and later on include new cloumns and then copy a records from old database?
I am using SQL Server 2008 Enterprise Edition R2.
I am working on a multi-lingual application Assume the following:
Database has 50 tables and application has to support 5 languages
Which is the best way to design the database:
1. Include a langugae column for each table. Repeat the values for each language. Say i have a country table which has 100 countries in it. Then my design will contain 500 rows (100 for each langugae)
2. Create a separate table which will contain the translations for all the 50 tables in with a foreign key to the parent table.
Which is more efficient out of the above two.
I have an entry from a database that has 500 characters. But when i display it i only want to return 200 charcters. How do I do that. I use Sql Server.

View 3 RepliesWhat would be the best database/technique to use if I'd like to create a database that can "add", "remove" and "edit" tables and columns? I'd like it to be scaleable and fast. Should I use one table and four columns for this (Id, Table, Column, Type, Value) - Is there any good articles about this. Or is there any other solutions? Maybe three tables: One that holds the tables, one that holds the columns and one for the values?
Maybe someone already has created a db for this purpose? My requirements is that I'm using .NET (I guess the database don't have to be on windows, but I would prefer that)
I have a partitioned db where several tables have the exact same structure. I'm able to query the tables using linq, but only by quering the individual tables 1 at a time and by using the explicit table name. For example at the moment, I have 8 tables so I have something similar to the following:
[Code]....
Is there any way, that based on a certain value (stringValue), I could determine which table to query and then code the linq query just once?
is there an easy way to compare two columns in two datatable to see if they match? I need to check if the values in column["x"] of datatable1 occur in column ["y"] of datatable2, without iterating through both tables (for each value in column of dt1, check column of dt2). I tried:
foreach (DataRow dr in dt1.rows)
if (dt2.rows.find(dr["x"]) but this checks the whole row and if finds an "x" in any column, "if" condition is true. I need to only check one column of dt2. Tables have different columns but the same primary column and that's what I need to check
