SQL Server Books Online says a schema "can be thought of as a conceptual object containing definitions of tables, views, and permissions."
But your boss probably just wants you to make a database diagram that has all the tables, relationships, keys, etc. in your database. The Diagrams node is right above the Tables node in the Enterprise manager. There isn't much to it.

schema is a logical representation of Business logic from a database.
example: You have a large ERP system and have 4 schemas One each for Accounts, Stock Control, Purchasing and Sales.
Consider it a logical database within a physical database.

I have seen this syntax in several news group posts:
Dim AccessCommand As New System.Data.OleDb.OleDbCommand("INSERT INTO Orders SELECT * FROM [Orders] IN '' [ODBC;Driver={SQL Server};Server=(local);Database=Northwind;Trusted_Connection=yes];", AccessConn)
but of course it does not work and of course I cannot find any reference to anything like it at Microsoft. Does anybody know where to find the documentation to this kind of syntax?

hello, i have a problem with the relations between 2 tables. I want to make a table with contacts and another table with websites. I want to have many website for 1 contact! SO 1 contact can have many websites. Can someone help me on this pls?

Naturally, the contact table will have a primary key (some sort of ID for each individual contact). The websites table will need to store this key also - but in the websites table it will be a foreign key (because it is the primary key of another table). The websites table will also naturally have a primary key of its own.
Is this enough to get you going?

Hi Adrian,
Are you using some kind of form in your .NET application as a database interface? If so, you can use an oleadapter/sqladapter to connect to your database. The procedure is quite straight forward (there is a Wizard). The data controls are on the Data tab of the Toolbox in the IDE.

When i use oledb.oledbconnection,i connect to SQL Server with this connection string :Provider=SQLOLEDB.1;Persist Security Info=False;User ID=sa;Initial Catalog=MDLABS;Data Source=SQL
But when i use sqlclient sql connection , i cannot connect to sql server.
my sqlclient connection string is
Persist Security Info=False;User ID=sa;Initial Catalog=MDLABS;Data Source=SQL
What is missing?

Try adding in the Instance name
e.g.
Source=SQL\SQLSERVEREXPRESS
or the password even if its blank

How extract the numbers only in the particular filed (Mobile_no).
ex. data’s like mr law ( 011-2231183)
House Fax:72336 6553
En Zaiadnal -202323204
I used replace but still the characters is coming

Well, one solution would be to create table with a column (tinyint) named HouseFax in which you would place the number 72336 6553. You wouldn't have any problem extracting the number then...

You could soemthing like this, not very clever but it works and you could alway put it in an UDF.
declare @Mob varchar(50)
set @Mob = '0122-1230-123'
set @Mob = REPLACE( @Mob , '-', '')
set @Mob = REPLACE( @Mob , ' ', '')
set @Mob = REPLACE( @Mob , '/', '')
set @Mob = REPLACE( @Mob , 'T', '')
set @Mob = REPLACE( @Mob , '\', '')
SELECT @Mob
Results
--------
01221230123

Is UDF slow? 
Norman Fung
|
|
|
|

Like anything, it depends how you use it.
For example:
SELECT * FROM A INNER JOIN B ON A.SomeValue = dbo.SomeUDF(B.SomeValue) isn't likely to be very quick.
What scenarios did you have in mind?

No UDF is quick due to it being precompiled on SQL server.
Although I have heard rumours its slower than stored procedures under certain situations; but I've never found any hard evidence to support this.

We're planning to use SQL 2005 Reporting Services, but first:
1. Is it as buggy as 2000?
2. Formular field and DTS packages: VBScript or C#?
3. Can you deploy reports built for SQL 2000 on SQL 2005?
Thanks in advance.

Hi everyone,
I have a small problem which I really need to solve today. I am doing a program which the user needs to log in. Now, when the user clicks the login btn, the username of that particular user is saved in a table called Marks.
Then a new form is opened in which the user can do a small exam and finally submit it. When he clicks the submit btn the mark is saved in the table, in the column called subjectMarks, near the username which was already saved before (in the column userName).
Unfortunately it is working wrong since the username is saved in the first row and then the mark is saved in the 2nd row.
How can I do it?
The following is the code I used in the submit btn:
string query = ("INSERT INTO Marks (" + subjectMarks + ") VALUES ('" + marks + "')");
OleDbCommand myCommand = new OleDbCommand(query);
myCommand.Connection = myConnection;
try
{
myCommand.ExecuteNonQuery();
}
catch(Exception ex)
{
ex.ToString();
}
Thanks

You need to do an UPDATE not an INSERT. You might want to take steps to prevent SQL Injection Attacks[^]
Also, from the limited amount of information that I have about your data model I have a feeling that it is not normalised properly. You shouldn't need to inject the column name in the way you are doing.

string query = "UPDATE Marks SET subjectMarks = '" + marks + "' WHERE userName = '" + cUserNameVar + "'"
This assumes that the username is unique in the Marks table, since every record with that user name will be changed to have the new subjectMarks value.
Either that, or you need an ID column - when you INSERT the name into the table from the login btn, get the ID and use that in the WHERE clause of the UPDATE when you put the subjectMarks in later.

hi
i have had that problem for some time now, where i wish to receive data from another source, format it into a datatable sturcture identical to a data table in my database, and pass said data table to an Oracle database in order to update said data table.
consulting with one of my DBA's i've been refered to the SYS_REFCURSOR object, however i could not find any explenation on it anywhere.
i would very much appriciate someone telling me first if i'm only daydreaming and what i want is impossible, and if it is possible, some way of coding it.

Hi,
I have a big trouble with connecting a SQL server database... 
The code for connecting SQL server database I used to connect to other SQL server database is as following:
Dim cnReg As SqlConnection
cnReg = New SqlConnection(ConfigurationSettings.AppSettings("MyConnection"))
cnReg.Open()
Dim dsReg As New DataSet
Dim comReg As New SqlCommand
With comReg
.CommandType = CommandType.Text
.CommandText = strSQL
.Connection = cnReg
End With
Dim daReg As New SqlDataAdapter(comReg)
daReg.Fill(dsReg, "Temp")
cnReg.Close()
In Web.config file
<appSettings>
<add key="MyConnection" value="Persist Security Info=False;Data Source=64.119.38.128;User ID=myid; Password=mypassword;Initial Catalog=mydb;" />
</appSettings>
The above code works correctly for my other projects. For my current project, since this hosting company doesn't allow external access SQL server database, I need to use server name, instead of server IP address, for the Data Source, so I change the setting in web.config as following:
<appSettings>
<add key="MyConnection" value="Persist Security Info=False;Data Source=whsql-v09.prod.mesa1.secureserver.net;User ID=myid; Password=mypassword;Initial Catalog=mydb;" />
</appSettings>
When I try to run the application, I got the error:
System.Data.SqlClient.SqlException: SQL Server does not exist or access denied.
I am using .NET Framework 1.1 and have SQL server service manager installed on my testing machine. Also, have McAfee personal Firewall installed.
I think, it's probably because there is something wrong with the setting on my local machine. I have spent the whole day trying to find out the problem, but still couldn't solve it...
Can anybody give me some ideas about how to solve the problem? Any advices and help would be very appreciated!
Thanks,
