Users For Encrypt And Decrypt Purposes Only

Jan 13, 2006

Hi there,

Using symmetric keys and certificates in SQL2005, can one assign users permission to only decrypt or encrypt data?

Reason would be say data capturer and data reader type roles. I tried to create some with the GRANT CONTROL and GRANT VIEW for certificates and definitions on Symmetric keys, but havent been to successfull.

Would be great if someone here can offer some advise on it, and if it's possible using SQL rights.

thanks

RC4 Encrypt And Decrypt

Jul 22, 2002

Hi Guys.

I am looking for TSQL code for RC4 encryption and decryption.

I found VBcode for RC4 encryption, it will take atleast 2 days for me to go thru that and rewrite the whole code in SQL.

If anyone has the code, please provide me.

(I know sql does accept extended ASCII characters)

Thanks

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, 2008

Does 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?

Using CURSOR For INSTR Purposes

Mar 21, 2007

TASK: At my work we want to categorize and summarize all our IIS web logs and make statistics from it and such. What I need to do is take the browser type from a certain column in the table. All the information is stored in 1 column, and I figure an instr function would be best to do this. I am new to SQL, so I was told to look up the cursor function. In summary, I want to take all the IIS data and match it up against a defined table and then have a sum function for each browser.

Here are some examples of what the column data looks like: (found in the [csMethod] column

Mozilla/4.0+(compatible;+MSIE+6.0;+Windows+NT+5.1;+SV1)
Mozilla/4.0+(compatible;+MSIE+6.0;+Windows+NT+5.1;+SV1;+.NET+CLR+2.0.50727)
Mozilla/4.0+(compatible;+MSIE+7.0;+Windows+NT+5.1;+.NET+CLR+2.0.50727;+.NET+CLR+3.0.04506.30;+InfoPath.2;+.NET+CLR+1.1.4322)
Mozilla/5.0+(Windows;+U;+Windows+NT+5.1;+en-US;+rv:1.8.0.8)+Gecko/20061025+Firefox/1.5.0.8

I made a define table which lists an ID (primary key) and instr to search for as well as the full browser name. (define.browser)

DEFINE.BROWSER

ID# INSTR# BROWSER NAME

Data Files For Testing Purposes

Feb 12, 2006

Can anyone give any advice to finding db files for testing. CSV files or what have you. I want to have some nice fun and repetitive Transact practice in creating db's and users etc. I have seen some online but I wondered first if anyone here used a site in particular that they could recommend. Would be nice to have files that may be standard (csv) and in another db format that I could use, mix it up some.

How To Limit Processors Used (for Licensing Purposes)?

Jul 18, 2007

Is it possible in SQL Server 2005 to limit the number of processors used? For cost reasons, we are consolidating servers and want to start running SQL Server 2005 on one of our dual-processor Win2K3 machines instead of the standalone machine it's currently running on. Because we have about 75 users, it's only cost effective to purchase a processor license (vs. a server license with CALs). But right now we only need and can only afford a single processor license, not two. So...

Is there any way in 2005 to limit the number of processors used so that we only need to purchase one processor license? I know in 2000 you could set this on the "Processor" tab of the "SQL Server Properties" dialog. In 2005, is this accomplished by unchecking the "Processor Affinity" and "I/O Affinity" checkboxes for processor #2 on the "Processors" page of the "Server Properties" dialog? If I uncheck these two options does that fully disable SQL Server 2005 from accessing the second processor in any way? From things I've read I can't tell if it restricts access to the second processor completely or if it just places some limitations on the ways it accesses the second processor.
Also, the licensing information for SQL Server 2005 leads me to believe that if you are going down the "processor licensing" route that you have to buy a processor license for every processor that the OS itself has access to and not just what processors SQL Server has access to. I thought I understood that in SQL Server 2000 the licensing information did allow you to buy a processor license just for each processor that SQL Server 2000 had access to, but has that changed for 2005?

Hope someone can provide some clarification on limiting processor access and the licensing implications for SQL Server 2005.

Thanks,

Scott

Extracting Data From A Table For Archiving Purposes

Sep 22, 1999

Hello,

I have been placed in the position of administering our SQL server 6.5 (Microsoft). Being new to SQL and having some knowledge of databases (used to use Foxpro 2.6 for...DOS!) I am faced with an ever increasing table of incoming call information from our Ascend MAX RAS equipment. This table increases by 900,000 records a month. The previous administrator (no longer available) was using a Visual Foxpro 5 application to archive and remove the data older than 60 days. Unfortunately he left and took with him Visual Fox and all of his project files.

My question is this: Is there an easy way to archive then remove the data older than 60 days from the table? I would like to archive it to a tape drive. We need to maintain this archive for the purposes of searching back through customer calls for IP addresses on certain dates and times. We are an ISP, and occasionally need to give this information to law enforcement agencies. So we cannot just delete it.

Sorry this is so long...

Thanks,

1:m Database Relation Flattened For Reporting Purposes

Jul 20, 2005

--Example Schema posted at end of message:---For reporting purposes, I need to build a single comma delimited string ofvalues from the "many" tableof a database.The easiest way to see what I want is to look at the sample after mysignature.By the way, this is actually a busines problem, not homework! I justcreated a simpleexample using class and persons because everyone is familiar with thatrelationship.I have two tables on the 'one' side of the relationship: PERSON and CLASSThe ENROLLMENT table resolves the many to many relationship between PERSONand CLASS.(I know that a real system would be date effective, etc, but this is just asimple example.that will show my problem). ENROLLMENT has one row for each Class in which aPerson is enrolled.Look at the sample report: I have to "flatten" the join result and listthe class titles in acomma delimited string. I am stuck with this reporting requirement, and Iam NOT going to denormalizethe tables.One way to accomplish the result is to use a cursor to step through the rowsand build a "Classes"string with concatenation. I don't much like this option. I am not writingthe front end code,but I want to make it easy for the developer. Ideally, I would like to givehim a flattened viewso he can just do a simple join and run his report.I believe that what I want cannot be accomplished with ANSI SQL. However,does MS SQL have someextensions that could help me do the job? Failing that, how could I write astored procedure that wouldreturn the personID and the "Classes" string in a format that would bejoinable to the other tables?Thanks,Bill MacLeanP.S.

Importing Report Content Direct To SQL Server For Testing Purposes

I have what seems a simple requirement. We want to import the contents of a SQL Server 2005 Reporting Services report into a SQL Server 2005 database, in order to perform some checks on reports displayed to users. Is there an easy way to achieve this? XML would seem appropriate, but I can't find a step-by-step guide on how to achieve this. Any pointers/suggestions would be appreciated.

Power Pivot :: How To Create Incrementing Sub Counter For (sort By Column) Purposes

Nov 16, 2015

I have a table ComponentPeriod. In it we have the combination of a component (e.g. A,B,C ) and a period (2014 Q1, 2014 Q2, 2014 January etc)I want the periods to be in descending order (2015 Q4, 2015 Dec, 2015 Nov, 2015 Oct, 2015 Q3 ... etc) and so I need to create a sequential number series to allow this to happen (as we can only order in the client tools by a single column - and so I guess the technique I'm looking for is used a lot to produce these types of "order by" columns)

I have done this in the past using

Period_Sequence =
calculate
(countrows(Period)
,filter
(Period
, Period[Start_Date] <= earlier(Period[Start_Date])
&& Period[Duration_String] = earlier(Period[Duration_String])
)
)

Which was fine when I was referring to a table where Periods where distinct directly but now I have denormalised this for ComponentPeriod so I need something a little more sophisticated Whats the best way to get a sequence with perhaps some partitions in across a subset of distinct columns (I guess from SUMMARIZE or similar)

E.g. I want

Period_Name, Type, Sequence
2015 Q4, Quarter, 1
2015 Dec, Month, 2
2015 Nov, Month, 3
2015 Oct, Month, 4
2015 Q3, Quarter, 5
2015 Sep, Month, 6
etc

even though there may be multiple records in ComponentPeriod that have the period 2015 Q4, but I want them all to have the value Sequence value of 1? I've got as far as:

Period_Sequence Desc =
calculate
(countrows(summarize(ComponentPeriod, ComponentPeriod[Period_End_Date]))
,filter
( ComponentPeriod
, ComponentPeriod[Period_End_Date] >= earlier(ComponentPeriod[Period_End_Date])
)
)

But this doesn't distinguish between the different types. I need an equivalent of the t-sql -

row_number() over (order by Period_End_Date desc, case when 'P3M' then 1 when 'P1M' then 2 end asc

Reporting Services :: Adding (new) Child Domain Users To SSRS As System Users?

Jul 28, 2015

We have an existing SSRS server, and have just created a new child domain. We'll be migrating users from the parent to the child, and want to add the users of that new domain with access to SSRS. In the parent domain they are able to access, but after migration with the child domain account, they cannot.

I have added the group CHILDDomain Users with a system user role on SSRS, and PARENTDomain Users was already there.

Is there any additional step I should/could take to get this active?
