I have a table that has an encrypted account number column. In order to give users access to the data BUT not access to the symmetric key used to encrypt the data, I'm trying to implement the following:
View 6 RepliesI'm exporting from a View using the bcp utility. I have the -t switch set for comma delimited. My first 3 columns are integers, but the rest of my columns need to be wrapped in double quotes because some of the string data contains commas. I can't find a simple way to do this, although I keep coming across notes about format files without any good examples.
Help?
I would like to wrap the following code in a function and reuse it. I use this code in many triggers.
DECLARE @Action as char(1);
SET @Action = (CASE WHEN EXISTS(SELECT * FROM INSERTED) AND EXISTS(SELECT * FROM DELETED)
THEN 'U' -- Set Action to Updated.
WHEN EXISTS(SELECT * FROM INSERTED)
THEN 'I' -- Set Action to Insert.
WHEN EXISTS(SELECT * FROM DELETED)
THEN 'D' -- Set Action to Deleted.
ELSE NULL -- Skip. It may have been a "failed delete".
END)
Is it possible to write a function and pass the INSERTED and DELETED logical tables to it?
I have created two user defined functions for encryption and decryption using passphrase mechanism. When I call encryption function, each time I am getting the different values for the same input. While I searching a particular value, it takes long time to retrieve due to calling decryption function for each row.
best way to encrypt and decrypt using user defined functions.Below is the query which is taking long time.
SELECT ID FROM table WITH (NOLOCK)
WHERE dbo.DecodeFunction(column) = 'value'
When I try to use symetric or asymetric encryption, I am not able to put "OPEN SYMETRIC KEY" code in a function. So, I am using PassPhrase mechanism.
I am looking to create a constraint on a table that allows multiplenulls but all non-nulls must be unique.I found the following scripthttp://www.windowsitpro.com/Files/0.../Listing_01.txtthat works fine, but the following lineCREATE UNIQUE CLUSTERED INDEX idx1 ON v_multinulls(a)appears to use indexed views. I have run this on a version of SQLStandard edition and this line works fine. I was of the understandingthat you could only create indexed views on SQL Enterprise Edition?

Hi guys 'n gals,
I created a query, which makes use of a temp table, and I need the results to be displayed in a View. Unfortunately, Views do not support temp tables, as far as I know, so I put my code in a stored procedure, with the hope I could call it from a View....
I tried:
CREATE VIEW [qryMyView]
AS
EXEC pr_MyProc
and unfortunately, it does not let this run.
Anybody able to help me out please?
Cheers!
I compared view query plan with query plan if I run the same statementfrom view definition and get different results. View plan is moreexpensive and runs longer. View contains 4 inner joins, statisticsupdated for all tables. Any ideas?
View 10 Replies View RelatedI had given one of our developers create view permissions, but he wants to also modify views that are not owned by him, they are owned by dbo.
I ran a profiler trace and determined that when he tries to modify a view using query designer in SQLem or right clicks in SQLem on the view and goes to properties, it is performing a ALTER VIEW. It does the same for dbo in a trace (an ALTER View). He gets a call failed and a permission error that he doesn't have create view permissions, object is owned by dbo, using both methods.
If it is doing an alter view how can I set permissions for that and why does it give a create view error when its really doing an alter view? Very confusing.
I have this view in SQL server:
CREATE VIEW dbo.vwFeat
AS
SELECT dbo.Lk_Feat.Descr, dbo.Lk_Feat.Price, dbo.Lk_Feat.Code, dbo.SubFeat.SubNmbr
FROM dbo.Lk_Feat INNER JOIN
dbo.SubFeat ON dbo.Lk_Feat.Idf = dbo.SubFeat.Idt
When ever I open using SQL Entreprise manager to edit it by adding or removing a field i inserts Expr1,2.. and I don t want that. The result I get is:
SELECT dbo.Lk_Feat.Descr AS Expr1, dbo.Lk_Feat.Price AS Expr2, dbo.Lk_Feat.Code AS Expr3, dbo.SubFeat.SubNmbr AS Expr4
FROM dbo.Lk_Feat INNER JOIN
dbo.SubFeat ON dbo.Lk_Feat.Idf = dbo.SubFeat.Idt
I don t want Entreprise manager to generate the Expr fields since I use the real fields in my application.
Thanks for help
I was wondering if anyone out there knows if it is possible to encrypt a particular field in a table, or encrypt a whole table. The info would remain on my database and not be sent out anywhere, but I just want an extra level of security against anyone who might try to break into the database.

Hello,
I am needing to migrate an Access database to Sql Server
Express. This database will be distributed as part of a
VB 6 application. This database will have some of the
columns encrypted. My understanding is that SQL Server
Express supports encryption. We will need to be able to
run queries on encrypted data like this, with
LastName being an encrypted column in the database.
Select LastName from Account where LastName = 'Smith'
Select LastName from Account where LastName Like 'Sm%'
Update Account Set where LastName = sLastName
Can this be done using SQL Server 2005 Express and VB 6?
Thanks!

I am using server 2005 running on a windows server 2003 platform. I am trying to do field encryption using symmetric key implemented by the AES algorithm. I created an AES key and apparently it encrypts the data with no problem, however when I try to retrieve the data after decryption the field is always null. I tried using the same process while using the DES or RC2 algorithm and I could both encrypt and decrypt information, however it does not decrypt for any of the AES algorithm i.e. AES_128, AES_192 and AES_256. Attached is a simple query I used to test it.
create symmetric key CCardKeys
with algorithm = aes_192
encryption by password = 'P@s$w0rD'
open symmetric key CCardKeys
decryption by password = 'P@s$w0rD'
declare @Id varchar(50)
set @Id = encryptbykey(key_guid('CCardKeys'),'Test')
select convert(varchar(50),decryptbykey(@Id))
close symmetric key CCardKeys
Is there something I'm missing with AES.
Thanks for taking the time to help me.
Here is my goal please let me know if it is possible.
I have installed sql express on clients machines. I don't want them to be able to view the sp's or the functions. I would like to go as far as not allowing them to see the tables. I tried with encrption but this is still breakable by the user using the DAC.

I have a user table with Fields:
UID, name, SSN, phone,address. I need to encrypt all the fields except UID. My company recently moved to sql server 2005 and I have to encrypt old data. We do perform query search based on username and SSN
I have very shallow knowledge of encryption and indexes. I did looked at one of the articles on encrypting data on existing application but could not understand the indexing part(:()
Do i have to define new fields with varbinary as datatype(for ssn, name,phone number) ? I am asking this because in the demo only ssn_index has varbinary and the ssn field is still nvarchar?
Any help will be appreciated.

I have tried to encrypt by certificate and by symmetric key. In all cases the decryption comes back as null. Any ideas why?
I have used the code from a learnin tree course and the encryption works OK. I have also added a grant to the certificate to the login
I am trying to create a encrypted row in my database Everything here worked except that when i run the final query to decrypt the data It just comes up with null for each row. Even if i do a query to show me the rows that are not null It's like it is saying yeah there is data here but I am only going to show you null instead of what I am supposed to decrypt.Here is what I tried from start to finish Create Certificate
TestCert
Encryption By Password = 'Password'
With Subject = 'SQLCert',
Expiry_Date = '12/01/2050';
declare @Test nvarchar(50)
set @Test='123456789'
insert into testenc (testencry)

(encryptbyCert(Cert_ID('TestCert'),@Test ))
select convert (Nvarchar(50),

Hi,
I have created a DTS package on my SQL 7.0 SP3 server which simply reads a table on another SQL 7.0 server and populates a local table with the information that has been read.
Whenever I try to execute the DTS package (via Run or scheduling it) I get the following error:
-------------------------------------------------------------------------
... DTSRun: Executing... DTSRun OnStart: Delete from Table [AfterSalesAccessories].[dbo].[model_derivative] Step DTSRun OnError: Delete from Table [AfterSalesAccessories].[dbo].[model_derivative] Step, Error = -2147217887 (80040E21) Error string: The property 'Use Encryption for Data' is not supported. Error source: Microsoft Data Transformation Services (DTS) Package
-------------------------------------------------------------------------
I have not selected the encryption option and can't see what I'm doing wrong.
Has anybone else seen this ? I've looked on Technet but no joy.
Thanks,
