Is there anything out there to encrypt my SQL 2008 server tables etc. so that only via passwords I can view the contents of it.
|

|

I'm not understanding something. Isn't the connection to the database userid/password authenticated?

Sometimes people don't want the admin to be able to see the data.
Being an admin I find that disturbing.

That's going to make the admin's job a little tough.

Here, I need your help. Please your comments, suggestions, expectation or potential interview Question (along with answer) here. Your input will be very valuable. As time goes by we all learn and get better. There were few things missing at that time when those interview questions and answers were prepared, now is the time to complete the gap and make this interview questions more useful.

Why are people uni-voting this? Did they bother following the link to his site? He has spent some considerable time on what should be a valuable community resource and all he wants is some help to make it better.

Hi Russell,
You have raised excellent point. I have worked very hard but just like everybody I can not make it better without the help of community and smart people.
I invite all the community members to help me build this interview Q and A, this way it is more useful to all of us in future. This will be on of the reference material for people who are new to industry and will know what to expect when they start their career.
Many thanks for your valuable point.
Kind Regards,
Pinal

Because it looks like an ad.
And if you follow the link it's about how to learn answers to common questions at interviews as opposed to learning a trade.
Having a site that gives you quick and simple answers to common database questions you might have, is brilliant, and I find it a good and wellwritten page as such.
But I find the purpose wrong.
And no, I haven't univoted him.

And if you read the text you will find that these misgivings have been discussed with collegues and various solutions suggested.
I don't think it is as one dimensional as you have implied.

So im designing a pm system for a game written in Ruby/On Rails and not quite sure how i would design the database side of the game to facilitate the desired features. The general message system looks like
Table: users
int userid
~ extra
Table: messages
int messageid
int authorid
longtext message
datetime timestamp
Table: message_to
int key
int messageid
int recieverid
What I'm looking to add is essentially custom folders. Meaning a user could create a "Diplomatic" folder and have the message appear under that folder. How would one go about facilitating the association between a message and a folder?
|
|
|
|
|
You need to create a table for folders i.e.
Table: folders
int folderid
text name
and then in meesages table add
int folderid.
Then when you access a message you know which folder it belongs to.
|
|
|
|
|
Yes but that doesn't hand ownership of folders would one do
Table: Folders
int folderid
varchar foldername
int userid
the do something like
SELECT foldername FROM table WHERE userid="x";?
then look into messages with
SELECT message, folderid FROM table WHERE receiverid="x";
then output based on folder?
|
|
|
|
|
Sorry, didn't get the part about folder ownership. This how I would set it up
Tables:
folders:
id int
name varchar
userid int
messages:
id int
fromid int
toid int
message varchar(250)
messagedate datetime
folderid int
users:
id int
name varchar
Then when you want to look up all messages from one person (say his id is 1) to another person (id = 2) in a particular folder (say id = 1) you would have a query like this
SELECT
m.message
FROM
messages m
INNER JOIN
folders f
ON
m.folderid = f.id
WHERE
m.fromid = 1
AND m.toid = 2
AND f.id = 1;

END
GO

It seems as though your tables have been set up not to accept null values. You either need to edit the table to accept nulls (probably not the best approach), or check whether your input values are not null before running the stored procedure(my preferrred approach) .
|
|
|
|

you kind of lost the thread there with your second post, however..
Either change the tables to allow nulls,
Or ensure no null values are passed to the procedure,
Or best of all, use isnull checks for each insert.
e.g.
INSERT INTO tbcontactaddress (emp_id,city,town,street, phone)
VALUES
(
isnull(@emp_id, '')
,isnull(@ccity, '')
,isnull(@ctown, '')
,isnull(@cstreet, '')
,isnull(@cphone, '')
)
Another consideration is that rather than passing so many parameters you may be better off passing it all wrapped up in a single XML parameter.

select spid, status, loginame, hostname, blocked, db_name(dbid), cmd from master..sysprocesses
Above query lists all hosts currently logged in using which login name.
But i want which hostname have logged in past using which login name . where do i found this information ?
Is there any log is maintained for that.

AFAIK, the information isn't stored historically. If you want to know who was online when, then you'll need to add some kind of logging.I are Troll

Why is the first procedure, faster than the second?
The ony difference are the extra local variables!
thanks,
A.

The question is why are you using 3 extra variables, that takes 3 extra cycles and therefore it is slower  Never underestimate the power of human stupidity
RAH
|
|
|
|
|
I can run it a 1000 times!
the difference is:
the first one with local variables: I get a result in 5 seconds.
the second one without local variables: I get a result in 20 minutes!!!!
Thank you

This looks like a problem caused by Parameter sniffing. Just google on it and you'll see what I mean.Wout Louwers

thank you all,
it has something to do with Parameter Sniffing!
It explains a lot!
Is this the best practice? to disable parameter sniffing?
Thank you
