Hi there,
How do I ensure case sensativity in SQL server? If I do a string comparison on "password" and on "Password" then they are exactly the same. This should not be the case. It should only be true if "password" = "password".
Please could someone help.
Thanks

Where do I change this? In Enterprise Manager?

Generally I set up the collation sequence when I install the server so all string columns use the sequence I want by default, however you can set it at the column level if you wish. I'm not sure if this can be done in the enterprise manager, I tend to script data model changes so I can run them as necessary. Something like this:
ALTER TABLE MyTableName ALTER COLUMN MyColumnName COLLATE Latin1_General_CS_AS

You can make a case sensitive test on any SQL configuration by casting the strings to varbinary . Paste this into Query Analyzer:
DECLARE @Test1 VARCHAR(20)
DECLARE @Test2 VARCHAR(20)
DECLARE @Test3 VARCHAR(20)
SET @Test1 = 'Hello World'
SET @Test2 = 'Hello World'
SET @Test3 = 'hello World'
--Normal SQL Compare
PRINT
CASE
WHEN @Test1 = @Test3 THEN
'SQL Compare: Test1 equals Test3'
ELSE
'SQL Compare: Test1 does not equal Test32'
END
--varbinary compare equal strings
PRINT
CASE
WHEN CAST(@Test1 AS VARBINARY(50)) =
CAST(@Test2 AS VARBINARY(50)) THEN
'VarBinary: Test1 equals Test2'
ELSE
'VarBinary: Test1 does not equal Test2'
END
--varbinary compare on case changed strings
PRINT
CASE
WHEN CAST(@Test1 AS VARBINARY(50)) =
CAST(@Test3 AS VARBINARY(50)) THEN
'VarBinary: Test1 equals Test3'
ELSE
'VarBinary: Test1 does not equal Test3'
END
|
|

Or you can just add a COLLATE statement to your comparison:
DECLARE @Test1 VARCHAR(20), @Test2 VARCHAR(20)
SELECT
@Test1 = 'Hello World',
@Test2 = 'Hello world'
--Normal SQL Compare
PRINT CASE
WHEN @Test1 = @Test2 THEN 'Test1 equals Test2'
ELSE 'Test1 does not equal Test2'
END
-- Case sesitive compare
PRINT CASE
WHEN @Test1 = @Test2 COLLATE Latin1_General_CS_AI THEN 'Test1 equals Test2'
ELSE 'Test1 does not equal Test2'
END

That is easier then the binary compare - good info. It does assume you know the language of the server. Not that a password test is a time consuming query, I wonder which is quicker; a conversion plus binary test or a language specific character test? I would assume the first since the other requires multiple comparisons per character. My wife tells me I am wrong most of the time so I would not trust my guess.

Looked at many ORM solutions.There are many open source projects.
I have implemented the ;
mapper pattern ______one class one mapper,
identity map_________manage the records that are read from the DB,
Seperated interface_________for having a simplier domain logic,
Registry_________________to centralize the mappers,
Finders__________________for finding objects,
DataSource________________for loading domain objects,
Type converter____________no casting (generics in c# 2.0),
List Loader_________________for loading list of domain objects,
Topological Sorting__________for not writing referantial integrity rules behind UI,
UnitofWork________________for storing the states of our objects for transactions(used system.transactions),
Connection Manager_________dot.net framework 2.0 feature DBProviderFactory is used to change the database providers,
Application Session Manager______for managing the sessions,
and I got all these from martin fowler POEAA,it took no more than a week to accpmplish these.Looked at hibernate and
Npersist they helped a lot.
Am I missing anything?Why anyone needs a commercial OR mapper with is not flexible?

Simple question, what is the easiest way to reinstall SQLServer2000
|
|

Hi gharry:
What exactly you want to do? Perhaps if running a old Service Pack, did you try with a newer Service Pack.
That should cause to remedy any of your problems with the current SQLServer instance you are facing.

The simplest way to reinstall something is to remove it and install it again

Yo i know that, i am not stupid. But i want to be sure that there are no databases lost when i remove the application.

The data files won't be lost if you uninstall SQL Server. However, you should have a backup of these already just in case.
When you reinstall SQL Server you will just have to attach these data files to the new instance of SQL Server. However, your logins will be lost as they operated at the server level, not the database level - so users will be orphaned from their login.

Then you should backup you databases and then proceed as I suggested , or simply stop the server and copy the mdf and ldf files corresponding to you databases you want to backup into a safe location...
I hope you understand...

Is there a simple way to duplicate / copy an en entire table?
I am using VC++ / ADO ( Access database) and I need to duplicate tables during the program run. It is my understanding that ALTER will rename but not build a new table.
Thanks for your time and help

Hello !
I have created two tables in access. The 1st table is "products" and the 2nd is "components". I have also established a relation of one to many using the editor in access. Now, from ASP.NET I wish to read a product, television, and its component, screen. Is it enough to call:
StrCommand = "SELECT TVscreenID FROM products WHERE ID = " + x + " ORDER BY ID"
OleDbDataAdapter da = new OleDbDataAdapter(StrCommand, conn);
da.Fill(ds,"products");
for accessing the details of the component 'screen' which is elaborated within the table components ? how do I access the details of the screen through the member 'TVscreenID' ? GetChild() or something? should I change the sql-string command to relate the both tables ?

hi,
I have problem in desktop application, how to connect remote sql server in my desktop application.
I have url of that db with user id and password.
Anyone can give guidance how to connect with remote dabase

You may need the IP address of the Remote Machine then only you can connect to the Remote Server. You cannot use the url name as the server name if your remote machine is a server and configured that machine as a DNS then you may can use the url (doubt).

Adding to the other comment, check that the firewall settings allow for external communication of SQL Server, and that it was installed (in the case of MSDE, I don't know about SQL Server) with DISABLENETWORKPROTOCOL=0 (not default).
