The Affinity Mask Specified Does Not Match The CPU Mask On This System.
Nov 17, 2007We are having a problem with one of our SQL servers, and in comparing it to the backup server which is working fine, I noticed some differences. I attempted to correct the differences, but no luck.
The dell server has 4 dual-core processors and at one point hyper-threading was enabled. One of our DBAs recommended that it be turned off. We didn't have any major problems until recently and it seems that getting this setting right is the lynchpin. Any suggestions?

SELECT - BETWEEN &<mask&> AND &<mask&>
May 10, 2004I have a table into which users can enter a To and From range, and an application returns all the values in between. Naturally the users can enter to and from values that don't exist, as all they need to do is satisfy a "between" expression. eg they can enter '1100' to '1399' and even though neither value actually exists in the data, the query will return all the values that fall into the desired range.
However the application now demands a bit more of a sophisticated approach. The target data may have the form 'nn-nnnn-nn' where n is '0' to '9', and the user wants to select all the values (in pseudo-code) which satisfy a pattern like '%-7040-%' and '%-7400-%'
A simple LIKE expression with a mask containing a RegEx won't work - ie LIKE '%-7[0-4][0-4]0-%' doesn't work because (eg) '00-7150-00' won't satisfy the mask because of the 5 falling outside [0-4], although it is within the range I want.
I have come up with a solution to this problem by using MIN and MAX aggregate functions on LIKE [From] and LIKE [To] respectively and this works fine. eg
"SELECT A.<something> from <target_table1> A, <table_with_ranges> B WHERE A.<something> BETWEEN (SELECT MIN(X.<something>) FROM <target_table1> X WHERE X.<something> LIKE B.[From]) AND (SELECT MAX(X.<something>) FROM <target_table1> X WHERE X.<something> LIKE B.[To])"
It's actually quite a bit more complicated than that - I have simplified the SQL a bit, but that is the basic algorithm.
The problem is that for the BETWEEN expression to work, both the MAX and MIN functions have to return a value that is not NULL- ie there has to be a value in the target table which satisfies the mask. In the application, this is not always going to be the case - Users will want to create large ranges to allow for future growth so every time they enter new data into target_table1 the don't then have to go out and redfine the [From] and [To] ranges to satisfy the new data. What I really need is an SQL expression along the lines of "SELECT .... FROM ... WHERE A BETWEEN <pattern1> AND <pattern2>" where <pattern1> and <pattern2> contain wildcards.
Anyone got any suggestions??? By the way, using SUBSTRING or other string functions is NOT an option for a variety of reasons.
What Happens If Affinity Mask And Affinity I/O Mask Are Not Mutually Exclusive?
Jan 21, 2008
I have a dual 64 bit quad core server with 16 GB of memory. We are going to run an application server and SQL Server 2005 SP2 CU4 64 bit on this hardware, but we only want to purchase a single CPU license for SQL Server. The obvious choice is to use the affinity settings to prevent SQL Server from using one of the CPUs.
Initially, the development team simply went into SSMS and unchecked affinity mask and affinity io mask for the first four processors. This appeared to work fine in their testing. A problem arose when we started monitoring the maintenance plan and saw that the database integrity check was failing. The root problem was this invalid state that the affinity masks were in.
I have seen a lot of documentation stating the SQL Server will ignore an invalid mask setting, but in our testing, it appears that SQL Server respects the setting. For example, when we set CPU 7 to be available for processing and IO, Performance Monitor showed that only CPU 7 was used during a load test.
So from our preliminary testing, it looks like SQL Server will use a single CPU for both processing and IO if you tell it to. Is there some other reason why these affinity settings need to be mutually exclusive? Is there a test I can run that can illustrate why?

SQL Server 2008 :: Trigger To Encrypt A Column?
Jul 23, 2015Can I accomplish encrypting a column with a trigger similar to below, but without the 'SSN' column?
I added the SSN column just so I could pass an UNencrypted value. Seems round-about & clunky.
This works:

Transact SQL :: Encrypt Server Column Using Trigger
Oct 20, 2015We have to encrypt one of the SQL Server column data at the database level, we don’t want to modify the application programs, because we use ERP application and we don’t want to reapply our customization very few months, so we are looking for an option to encrypt and decrypt the column level data value using trigger/procedure/function, I used instead of trigger on that table to encrypt and decrypt the values but it is not working, we want only one user(Application Service account) have an ability to encrypt and decrypt the data, not for any other id.. I read somewhere we cannot automatically encrypt/decrypt the column value using trigger, is that true...

View 9 Replies View RelatedAffinity Mask And Affinity I/O Mask Configuration
Sep 17, 2007I'm experiencing some problem with the affinity mask and affinity I/O mask configuration.
We are running SQL Server Enterprise Edition 2005 64bit on Windows 2003 Server 64bit with 4 dual core CPU. The actuelly configuration is:
Affinity Mask Affinity I/O Mask
CPU0 0 0
CPU1 0 0
CPU2 1 1
CPU3 1 1
CPU4 1 1
CPU5 1 1
CPU6 1 1
CPU7 1 1
We did it so, because we are running LiteSpeed Tool for the backup. LiteSpeed is configured to use CPU0 and CPU1.
Now, we know that the settings are wrong. If Affinity mask is 1 affinity I/O mask should be 0 and vice-versa.
My question is: how many CPU should I enable for affinity mask and how many for affinity I/O mask. Which are the correct criterias.
Thx in advence.

Possible To Encrypt Database Assembly?
Oct 11, 2006Hello.
I've built a simple Visual Basic .NET project containing the following code...
Imports System
Imports System.Data
Imports System.Data.SqlClient
Imports System.Data.SqlTypes
Imports Microsoft.SqlServer.Server
Partial Public Class StoredProcedures
<Microsoft.SqlServer.Server.SqlProcedure()> _
Public Shared Sub WhoAmI()
Using connection As New SqlConnection("context connection=true")
connection.Open()
Dim command As New SqlCommand("SELECT SUSER_SNAME()", connection)
SqlContext.Pipe.ExecuteAndSend(command)
End Using
End Sub
End Class
From Visual Studio, I want to encrypt the contents of this assembly, as a proof-of-concept.
Even though assembly contents are stored as varbinary(MAX) in the database, converting to varchar(MAX) will expose the code.
However, the Dotfuscator Community Edition reports the following error: "Dotfuscator Community Edition cannot operate on SQL Server applications.... please try Standard or Professional Edition."
Has anyone tried encrypting a database assembly and deploying to the database?
A good test would be to issue the following TSQL script against the database holding the assembly...
-- Does the sample code above run?
EXEC dbo.WhoAmI
GO
-- Is the code readable?
SELECT * , Convert(varchar(MAX), content) FROM sys.assembly_files

Stripping Input Mask From Phone Numbers
Mar 28, 2006Hello, I have this Access 2K query that I need to re-create in MS SQLServer 2000, so I'm using the Query Analyzer to test it.One of the Access fields stores the home phone number. In the Accessquery, if the phone number is null, it fills it up with zeroes"000000000." If the phone has an input mask, it only gets the 9 numbers(area code included) and if the phone number's good (all numbers) thenit leaves it alone. That Access query is using immediate ifs toaccomplish that task.Does anyone have any idea how to copy this behavior into SQL Server2000? I've using the CASE statement but so far my code is not correct.I get stuck in the input mask. This is the Access code:HomePhone:IIf(IsNull([HomePhone]),"0000000000",IIf(Left([HomePhone],1)="(",Right(Left([Homephone],4),3)& Right(Left([Homephone],9),3) & Right([HomePhone],4),[HomePhone]))Thanks for all your help.JR.

Forcing Data Format Mask Without Modifting Code
Sep 24, 2004I have statement which is comparing a smalldatetime column to literal string as follows:
sales_date ='21-9-2004 0:0:0.000'
when I run the statement in query analyzer it bombs out with:
Server: Msg 296, Level 16, State 3, Line 1
The conversion of char data type to smalldatetime data type resulted in an out-of-range smalldatetime value.
If I alter the format of the date literal to '2004-09-21 00:00:00' the statement works.
Is there anyway of forcing the statement to treat '21-9-2004 0:0:0.000' as '2004-09-21 00:00:00' without modifying the statement itself ?

SQLStatement.printf("select c.value from master..sysconfigures c, master..spt_values v,"
"master..syscurconfigs r where v.type = 'C' and v.number = c.config and v.number >= 0 "
"and v.number = r.config and v.name ='affinity mask'");

Database Diagrams : Showing Relations Column To Column
Dec 19, 2005Hi to all,
As I am going to deal with a huge number of database tables, I thought that drawing their diagrams will be the most professional way of keeping track of what I am doing. So In Enterprise Manager using the Wizard I made it to be drawn nicely.
But I have a problem now. I see that the relations defined among the tables are represented correctly but the line connecting the two table is drawn randomly. I mean the starting point of the line doesnt start from the column having the primary key and doesnt end near to the column having the foreign key. Viewing my diagram I want to see the lines to start and end showing the 2 related key columns.
Is there a way to accomplish this like setting an option, clicking somewhere or should I try to drag the lines to manually?
Thanks in advance
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.
