Load on SQL Server Database

Hi,
How do we find the load on the SQL server database. even i am not
asking in the right mannar but i will can explain my problem then u
suggest me the right way to clear my problem.
i have written my code in C++,i am using multi threading and my
database is SQL Server.
i closed the connections perfectly still, i am seeing the connection
leak on Performance Viewer.
So i disabled some of the SQL Statements so very very very very slowly
, the connection leaks are growing. like propostional to disabling the
SQL Statements growing of connection leak.
so i thought it will be load balancing factor of the SQL Server or my
thing will be worng please any body help me.
In short, I want to know if the load on the SQL Server can cause
connection leaks? and if yes, then how can we define load on the SQL
Server database.
Thanks in advance,
RSTake a look at Perfomnace Monitor

Load Multiple Signed Assemblies

I am trying to load multiple strongly named assemblies into the same database which are signed with the same .snk file (signed in Visual Studio). I use the following code to create an asymmetric key and login as Books Online recommends:

CREATE ASYMMETRIC KEY SQLCLRKey FROM FILE = 'D:\dba\bin\Assembly.dll'

CREATE LOGIN CLRAssembler FROM ASYMMETRIC KEY SQLCLRKey

GRANT UNSAFE ASSEMBLY TO CLRAssembler

GRANT EXTERNAL ACCESS ASSEMBLY TO CLRAssembler

REVOKE CONNECT SQL FROM CLRAssembler

Do I need to create a new login and asymmetric key for each assembly I load? If so, do I need to sign each with a different key because its giving me an error message when I try to create 2 separate asymmetric keys/logins from 2 different assemblies which have been signed with the same .snk file.

The only way I've gotten everything to load properly is to create a separate key for each assembly and sign each, then create separate logins and asymmetric keys in the database.

Is this the only way to do this? Or am I missing something?

First of all I think you mean:

CREATE ASYMMETRIC KEY SQLCLRKey FROM EXECUTABLE FILE = 'D:\dba\bin\Assembly.dll'

FROM FILE = '...' requires a file that has both the public and private key in it, but an assembly has only the public key in it. Also you should be creating this key in the master database.

In order to use an asymmetic key to enable an assembly to be loaded the asymmetric key must be the master database and include public key, but the private key is not required. When FROM EXECUTABLE FILE = '...' is used the only the public key for the asymmetric key is saved. This key can be used to create a login to grant usafe assembly to. Then, assuming the use has the other appropriate permissions, any assembly signed with this key can be loaded with permission_set = unsafe. A single login is used to load all of the assemblies that are signed with the same key... you can't load the same asymmetric key more than once in the same database. You will have to be sure that Visual Studio is signing all your assemblies with the same key. If you are having to create a new login for each assembly it sounds like Visual Studio is creating a new key for each of these assemblies. When you go to the properties for your visual studio project browse for a common key, don't create a new one.

You can create the asymmetric key directly from the snk file that visual studio creates, for example if myKey.snk is the key pair created by visual studio then:

USE master
GO

CREATE ASYMMETRIC KEY [MyAssemblyKey] FROM FILE = 'c:\keys\myKey.snk'
-- remove the private key, no reason to leave it hanging around.
ALTER ASYMMETRIC KEY [MyAssemblyKey] REMOVE PRIVATE KEY

CREATE LOGIN [LoginMyAssemblyKey] FROM ASYMMETRIC KEY [Key MyAssemblyKey]
GRANT EXTERNAL ACCESS ASSEMBLY TO [LoginMyAssemblyKey]

GO

Once you have done this any assemblies signed with myKey.snk can be deployed from visual studio with unsafe permission set.

My mistake. I did mean EXECUTABLE FILE.

I started out trying to sign them all with the same key and then loading them individually and dropping the key and login, however this was producing an error (which I can post once I get back into the office).

Do I need to load them in the same batch or script if I want to use the same login? Because I was running them separately.

If not, how do I specify the login to use? I tried using the AUTHORIZATION command with it and it threw a permissions error.

|||

I'm not sure what you mean when you say you drop the login after creating the assembly.

If you drop the login, or take away the login's USAFE ASSEMBLY permission, you will not be able to use the assembly even though even though it has been created. The login created with the assemblies key is required whenever any function from the assembly is used.

Dan

You need only use CREATE ASSEMBLY. Authorization is used to specify an owner, it is not related to whether or not the assembly can be external acess or unsafe. If the assembly is being created WITH EXTERNAL_ACCESS or UNSAFE, SQL Server will use the key inside of the assembly to find the login created with that key, then check the permissions granted to that login. It, in effect, does this whenever a function from that assembly is used too.

Load images into Sql Server 2005

Hi There

I have not had much luck finding info in BOL for tsql or SSIS that tells one how to load images on the file system into sql server 2005.

All i have really been able to find is that IMAGE data type will not be used in future and that one should use a varbinary(max) data type.

I am thinking of using a for each file loop in SSIS, but then how do i load the images (.tif) into a sql server database table ? Perhaps i need to use a sql task with the filepath , or an active x script.

Anyway if anyone knows how i can load images from the file system into sql server 2005, please let me know.

Thanx

Hi,

U can use Activex Script. But it is better to use Script task.

|||

You should look at the Import Column component. http://msdn2.microsoft.com/en-us/library/ms141262.aspx

All you need is a source file or table, with a column containing the filenames you wish to insert. SSIS will then load each named file into the data flow, from whence you can insert it to the database as normal.

Choice of the best data type for storing images would be better discussed on the SQL Server engine forum.

Hi Donald

Would a for each file loop not work better, as a source file or table is not realistic considering there are over 9 million flat files.

I am not sure i am following you, import column requires a data source, if i point a flat file source to a image file it gets very confused with randon columns and junk data. I am not sure how to feed the flat file image to the import column task?

I have figured out another way to do it. But i am also interested in your suggestion.

Thanx

|||

That is indeed a lot of files. Actually it is so many that you may want to contact me offline to discuss options. DonaldDotFarmerAtMicrosoftDotCom will get me.

One way to generate a suitable file as a source, may be to pipe a dir command to file and then parse the result using SSIS - either using a flat file source, or a script component. From there it would be relatively simple to implement your scenario.

Donald

Thanx Donald

I am gonna try a couple of things and i will get back to you.

The TextCopy utility is a great way to load binary data into BLOB fields. I am calling the util from a .bat file. Its another option anyway....

the t-sql OPENROWSET BULK statement is designed to import files into sql server: http://msdn2.microsoft.com/en-us/library/ms190312.aspx

this statement can then be used in an execute sql task.

i suggest that you consult with the t-sql forum if you need assistance with this statement.

Load image file

HI

how to load a image file in to a sql server.

do we need c# code for it or can we use just a t-sql procedure to upload it.

In my application we don't have ant c# or other application. we have only t-sql

thanks

sandipan

If you are planning to use SSIS, the Import Column transform could be useful for this purpose.

Thanks.

Load from several CSV files

I have to load around 68 CSV files into one table. I have named the files
1.csv thru 68.csv. Is there a way I can don't have to make 68 packages to
load these. I am not very proficient with VBScriptTry using a global variable for the file name, a Dynamic Properties Task and
an ActiveX Script Task to programmatically loop through and change the name
of the input file for each import.

C:\>copy /?
Copies one or more files to another location.
COPY [/D] [/V] [/N] [/Y | /-Y] [/Z] [/A | /B ] source [/A | /B]
[+ source [/A | /B] [+ ...]] [destination [/A | /B]]
source Specifies the file or files to be copied.
/A Indicates an ASCII text file.
/B Indicates a binary file.
/D Allow the destination file to be created decrypted
destination Specifies the directory and/or filename for the new file(s).
/V Verifies that new files are written correctly.
/N Uses short filename, if available, when copying a file with a
non-8dot3 name.
/Y Suppresses prompting to confirm you want to overwrite an
existing destination file.
/-Y Causes prompting to confirm you want to overwrite an
existing destination file.
/Z Copies networked files in restartable mode.
The switch /Y may be preset in the COPYCMD environment variable.
This may be overridden with /-Y on the command line. Default is
to prompt on overwrites unless COPY command is being executed from
