Encrypt Data In Database
Jun 23, 2007Hi,I have a .net application and i added a code that encrypts data saved in database. However, there is already data in the fields that was entered before this change.I know need to check if the values in those fields are encrypted and if not i need to encrypt them.How can I perform such a check and update the relevant data?I use TrippleDES in .net to encrypt/decrypt the data.Thanks

Best Approach To Encrypt Data?
Sep 12, 2007Hi,
I want to encrypt certain data like password, ssn, credit card info etc before saving in database. Also, this encrypted data can be queried using standard SQL statements like:
select * from users where userid=454 and password = 'encrypted data'
The mechanism to encrypt data could be in a .net application. The code that does encryption/decryption should also be protected so that it doesnt work if it falls in wrong hands.
Can anyone suggest what would be the best way to accomplish above?
thanks,

Encrypt Data In A Stored Procedure
Jul 11, 2006I am trying to insert data in a table using a stored procedure, but somehow I cannot store the values passed by the stored procedure in the table.
Table has two fields FIRST_NAME, LAST_NAME with varbinary data type(I need to encrypt the data)
My stored procedure is as follows. Please let me know what i am doing wrong!
***************************************************************
ALTER PROCEDURE [dbo].[SP_InsertInfo]
-- Add the parameters for the stored procedure here
@FIRST_NAME varBINARY(100)
,@LAST_NAME varBINARY(100)
AS
OPEN SYMMETRIC KEY key DECRYPTION BY CERTIFICATE cert
BEGIN
SET NOCOUNT ON;
-- Insert statements for procedure here
Insert into [dbo].[INFO] (FIRST_NAME, LAST_NAME)
Values ( encryptbykey( key_guid('key'),'@FIRST_NAME'),
encryptbykey( key_guid('key'),'@LAST_NAME')
)
close SYMMETRIC KEY key
END
**********************************************
EXEC sp_InsertInfo 'larry', 'Smith'
when I run the SP, the data stored in the first_name, last_name fields are @FIRST_NAME', @LAST_NAME' instead of larry, smith respectively.

Hash/Encrypt CSV To Lookup Repeating Data?
Oct 1, 2007Hopefully this makes sense, not sure what to even begin researching...
I'm trying to optimize all facets of this process, as it will take over the resources on my server if not done efficiently.
I have CSV files containing INTs that I need to upsert (match to an existing/earlier imported array or create a new record set) millions of times a day. To be clear, this data is a small subset of the actual import, this arrays contents are not the main data of the process, and the value of the entire array is meant to be related to higher level tables.
The contents of the CSV array are 99.9+% repeating, meaning they will very often share the exact same contents as a a previously imported array. A rough guess is there are 20k combinations existing, and less than 1k new per month, and will range from 6 cols x 15 rows to 6 cols x 50 rows.
So current plan is to use a MD5 hash during the (not SQL related) export process to identify the contents of this CSV file, and export only the md5 (32 digit hex) as a lookup to identify the contents. If the SQL import process finds a new (unknown) MD5 it will request the actual contents, otherwise it will simply use the MD5 as a key/id/code for the actual array contents that are already stored.
There's probably a certain terminology I'm not familiar with for this type of thing.. I've never heard of something like this. I realize collision is a threat, but I'm unsure how much I should be worried about it with this type of data (similar size/contents, but a relatively small amount of possibilities). I think up to even 0.1% collision would be acceptable which is probably way more than enough.
Does this sound like a bad idea to anyone? Are there certain hash functions I should use for this type of thing? Anyone have suggestions of where to look next?
Thanks!

Aug 20, 2007Hi!
Need help with this one:
I have a column with a string composed by several data. After using REPLACE several times, I get something like the data below, which has (in most of cases) a value and a date.
378 9/05

4/06 164
The problem is that I need to get each value alone (to separate columns), in example:
Value Date
378 09/2005
388 09/2005
0 04/2005
...
606 01/2006

In addittion you can see that sometimes the Value come first or alone, and sometimes the Date come first or alone.

Encrypting Data Using TSQL
Aug 7, 2006I need to find a way of encrypting and decrypting data from SQL server 2000. I need to do this as transparently as possible, which is why I need to do this if at all possible before my web application encounters the data.I know this is possible without 3rd party applications using SQL server 2005, as I have a working implementation already; however I need to do this with SQL server 2000 as upgrading is not an option. Using a 3rd party product to encrypt/decrypt is also not possible.Any help much appreciated.Matt Rose

Manipulating Text,nText Data Types Filed In Tsql
Jul 12, 2006I have to run a dynamic sql that i save in the database as a TEXT data type(due to a large size of the sql.) from a .NET app. Now i have to run this sql from the stored proc that returns the results back to .net app. I am running this dynamic sql with sp_executesql like this..
EXEC sp_executesql @Statement,N'@param1 varchar(3),@param2 varchar(1)',@param1,@param2,GO
As i can't declare text,ntext etc variables in T-Sql(stored proc), so i am using this method in pulling the text type field "Statement".
DECLARE @Statement varbinary(16)SELECT @Statement = TEXTPTR(Statement)FROM table1 READTEXT table1.statement @Statement 0 16566
So far so good, the issue is how to convert @Statment varbinary to nText to get it passed in sp_executesql.
Note:- i can't use Exec to run the dynamic sql becuase i need to pass the params from the .net app and Exec proc doesn't take param from the stored proc from where it is called.
I would appreciate if any body respond to this.
How To Find Differences In Column Data Types Between Tables In Two Different Databases Using TSQL
Apr 21, 2008
I have Two Database that exist on Two seperate servers. The two database contain same schema and contains tables and columns of same name. Some tables have slight differences in terms of data types or Data type lenght.
For example if a Table on ServerA has a column named - CustomerSale with Varchar (100, Null) and a table on ServerB has a column named CustomerSale with Varchar (60, Null), how can i find if other columns have similar differences in all tables with the same name and columns in the two servers.
I am using SQL Server 2005. And the Two Servers are Linked Servers
What Script can i use to accomplish this task. Thanks

TSQL + VBA - Retrieve SQL SERVER 2000 Data Trough Excel 2003 - Time Out Error 80040e31
Sep 17, 2007Hi guys,
When I thought everything is okay with this script, I got a new problem...
I have a VBA's script from Excel 2003 that builds sql script and retrieves data from SQL SERVER 2000.
in order to make the sql running, I need to use a multi - batch processing, to pass and execute every command line once a time.
Up to here, I am using a test case with Account number = '123456' and getting the desire results.
The code below is running okay with the test case, but when changing the account number (mark as yellow in the code) to include all the accounts (or just one other account), I am getting the following ERROR:
run - time error '-2147217871 (80040e31)' - [Microsoft] [ODBC SQL Server Driver] time out expired.
Now, if I take the same code, with the condition that generates the ERROR, and try it into SQL Server, I get the results without errors.
Thanks in advance,
Aldo.

Encrypt Function
Feb 16, 2003Hi all
I have got an application developed on SQL7 which I have migrated to SQL2K.
It handles authentication internally and therefore stores usernames & passwords in a local table. The passwords are stored encrypted utilizing a function called "encrypt" taking the password in clear-text and returning a varbinary. When a user logs on his password input is encrypted the same way and compared to the stored password. So far so good...
Problem: On SQL2K the encrypt function returns a different result as it does on SQL7., which reults in authentication failures.
Unfortunately I cannot find any documentation about the encrypt function e.g. in BOL. Furthermore I cannot ask the developer who introduced the function anymore.

Encrypt On CLR Decrypt In SQL?
Jan 8, 2008
Hi folks,
I'm trying to encrypt a small token of data on my client c# application and have it decrypted by SQL on the server side, the problem is i cannot find articles on the subject. I don;t really want to get involved with certificates but base the system on a simple symmetric key that is shared by both parties.
I'm attempting to use the TRIPLE_DES algorithm on both sides and thus far have used the decryptbypassphrase on the server side with the data encrypted on the client side by .Net with no initialization vector setup.
If anyone can recommend any articles or have example (client and server side) code for this situation it would be greatly appreciated.
Many thanks in advance

Encrypt In .net, Decrypt In Sql
Feb 29, 2008Does anyone know what my .net app guys need to share with me if encryption was done in the .net app but decryption needs to occur in certain sql queries? I read about master keys, certificates, symmeteric keys, algorithms etc but dont know how that stuff would carry over from the framework into sql. All I know is that the algorithm is AES_256, they must be adding authentication to the encryption and i know the hash algorithm, and symmetric keys are involved. Will they be sharing certain kinds of files with me that need to be registered in the db? Will I have to use CLR if I want the two worlds to come together?
