It really depends on what you are going to do with the information. If all that will ever happen is that the phone number gets displayed on the screen for a customer services person to see and then dial the number then having phone1, phone2 etc. is probably fine.
If you are storing more than just the phone number you might consider normalising it. e.g. for each phone number you are going to put what type of number it is (work, home, mobile, fax, etc.) and maybe a description, e.g. "Available between 9:00 and 18:00"
Alternatively, if you are going to do any serious processing with phone numbers (and I really can't imagine what that could be outside of a telco or automated call centre scenario) then you would be better normalising the data otherwise the SQL will get horrendous.

How do I sort a Dataset by a certain column value? The data will be bound to a datalist. The only sorting I've found is for the datagrid web control.

Select name from sysobjects where xtype='u'
SELECT table_name FROM INFORMATION_SCHEMA.TABLES
These two performs one nad the same
But when executed in Query Execution Plan the first query costs less
So I prefer the first one

I am writing a program that updates a access database. I am filling a dataset with data from a comma delimited text file. Then I insert the dataset into the database with this piece of code.
OleDbAdapter.Update(dataSet1, "Table1");
This works great, but I also need to insert records to the database using a SQL insert statement. I am using the code below to insert a single record to the database.
"insert into Table1(col1, col2, col3)"
+ " values ('" + textBox1.Text + "', '"
+ textBox2.Text + "', '"
+ textBox3.Text + "')";
This works great. The problem comes in when I try to insert another dataset. The correct number of records are added but every row is the same as the row from the SQL statement. I bound the dataset to a datagrid but the datagrid shows the correct data in each row. Please help me before I get fired. Thanks

SELECT * INTO NEW_tblName FROM EXISTING_tblName WHERE 0 = 1
--SQLServer Books Online--
INTO Clause
Creates a new table and inserts the resulting rows from the query into it.
The user executing a SELECT statement with the INTO clause must have CREATE TABLE permission in the destination database. SELECT...INTO cannot be used with the COMPUTE. For more information, see Transactions and Explicit Transactions.
You can use SELECT...INTO to create an identical table definition (different table name) with no data by having a FALSE condition in the WHERE clause.

There go my people. I must find out where they are going so I can lead them.

I have successfully retrieved data with an adapter to create my required dataset. But now I want to know how many rows are in my dataset? I am using SQL 2003 and .NET1. I see that many people use the Tables.Rows.Count, but mine isn't working when I do that.
How do I retrieve the number of rows of the table in the dataset?
Thanks.

|

please try the following code
dim ds as new dataset<br />
dim da as new sqldataadapter(strQuery,conn)<br />
da.fill(ds,"test")<br />
response.write(ds.tables("test").rows.count)
strQuery is the select command, conn is the connection

//this should answer your question
string connStr = "Fill in your connection string here";
string sqlStr = "SELECT * FROM someTable";
System.Data.OleDb.OleDbConnection conn = new System.Data.OleDb.OleDbConnection(connStr);
System.Data.OleDb.OleDbDataAdapter da = new System.Data.OleDb.OleDbDataAdapter(sqlStr, conn);
System.Data.DataSet ds1 = new DataSet("test");
System.Data.DataTable dt1 = ds1.Tables["someTable"];
int rowCount = dt1.Rows.Count;
//or a good use is
for(int i=0; i< dt1.Rows.Count; i++)
{
//do something
}
//or another
foreach (System.Data.DataRow dr1 in dt1.Rows)
{
//Do something else
}

Hey,
Anyone knows where the databases/tables, created on SQL Server2000, are located.I mean the actual path to which I can navigate to from windows browser.
Thanx & Regards.

In Query Analyzer type the following in, while connected to the master database:
select name, filename FROM sysdatabases This will give you the operating-system path and name for the database's primary file.
Alternatively, you can connect to a specific database and perform
SELECT * FROM sysfiles This will get the details of the files for the current database.
