I know the rule of thumb is to use T-SQL when manipulating data and to use SQLCLR for conditionals, looping, etc. My question is how much slower (percentage, factor of, anything!) is SQLCLR for doing SELECT, INSERT, and UPDATE commands?
Is the performance difference *that* much greater that the simplicity of SQLCLR doesn't apply?
Hi. this is a tricky one to explain but I'm at a bit of a loss
Consider a product demand table such as
ProductDemand Qty
Prod 1500
Prod 2300
Prod 30
Now consider a Inventory table such as
Product BatchTotal qtyFree qty
Prod 1Batch 13000
Prod 1 Batch 2300100
Prod 1Batch 3200200
Prod 2Batch 22 600300
Wha I am trying to achieve is the "Free Qty" column such that, within each product, the demand is "comsumed" by each batch in turn until completly comsumed (or no batches are left). Hence the demand of 500 would result in 300 going to zero for batch 1, carry forward 200 demand which would be completly comsuemd by batch 2 leaving 100 "free". Subsequnet batches would remain all free for that first product. Then the operation continues for the next product.
How on earth do I do it ?????
Thanks for you thoughts

Hi there.
I work for a charitable organization, am new to this form (and sql programming) and trying to create a flag for unique records indicating the number of consecutive years a donor has given.
I have create a sample db idenifying donor, giving year and total pledges with multiple donor records existing for multiple years having donated.
CREATE TABLE mygifts06 (Donor_id varchar (10), Gift_yr nvarchar (4), Tot_pledges numeric (16,2))
INSERT INTO mygifts06 (Id,Gift_yr,Pledges)
SELECT 155758,2005,15.00 UNION ALL
SELECT 155759,2004,25.00 UNION ALL
SELECT 155758,2004,40.00 UNION ALL
SELECT 155757,2005,100.00 UNION ALL
SELECT 155758,2002,30.00 UNION ALL
SELECT 155758,2001,120.00 UNION ALL
SELECT 155755,2003,15.00 UNION ALL
SELECT 155758,2006,80.00 UNION ALL
SELECT 155757,2003,65.00 UNION ALL
SELECT 155759,2005,400.00
For the above dataset, I am trying to create the following output
Donor_id 2_consec_gifts 3_consec_gifts 4 consec_gifts
--------- -------------- -------------- --------------
155755000
155757000
155758110

Do I need to use a cursor for this task? I lack experienced in using cursors is there an alternative method someone could suggest?
Thanks in advance.
Hello,
is there any way to measure the progress of a synchronization operation so as to show a progress bar to the user?
Best regards,
Marcos Ruano
Is there any way to measure the progress of a long running query,
for instance, to find where in a query plan a query is in SQL 7.0?
I have a query I am running that is currently 2 1/2 hours into the
query. Since it's joining three large tables, one with 42 million rows
and two with 7 million rows, I'm expecting the query to take a
while. However, I have no way of estimating exactly how long
it will take. Before I ran it, I optimized it the best I could in
Query Analyzer using an estimated query plan, making sure I had
all the right indexes, etc. I've been trying to use the estimated cost
to project query time, but that hasn't been working since queries
with similar costs can take radically different amounts of time to
execute.
Now I'm sitting here waiting, wondering if the query is just taking
too long, and I should stop it and work on optimizing it some more
(since I will have to run a couple more queries like it), or let it
finish. But I have no clue how close it is to finishing. I've tried looking
at the Physical I/O given by sp_who2 and then trying to calculate the
number of pages it would have to read if it had to read everything
from disk, then estimating it's progress by that, but this seems dubious
at best, since I don't know a whole slew of factors (ie: how many
pages are being read from the cache, is my page calculation correct,
etc).
So, does anyone know of any way to figure out how soon a long
running query will finish in SQL 7.0?
Thanks.

Here is a brief description what I am actually looking at. As we all have SLA's to understand how much uptime/downtime we can afford maybe per year/per quarter. I am keenly interested in finding out the way of calculating the sql server uptime. I googled for this and didn't find an appropriate solution that can justify my needs.
I am looking at a way that can give me a historical view of the uptime (possibly aggregated over time), considering all the facts for e.g I am not considering the maintenance that we do for keeping our servers up to date which includes patching and stuff, instead I am more focused on the historical view that for e.g if my manager asks me to give him a report stating the uptime for all the sql servers that we have for the current quarter.
Hence, I would basically some kind of script wherein I am storing the history somewhere and at a later date if my manager asks me to give a quarterly uptime report I can pull out that aggregated data, and generate a pie chart or something from that data to show the uptime and downtime for the same. I don't want to use 3rd party tool and I know there are quite a few, but company won't afford it.
I want to measure updates/Insertion rate of my databse in order to measure that how percent the databses is booked for insert and update.
can some one can suggest me the mechanism or other resource for doing this work...
thanxs in advance
How I can measure the volume of data created temporarily to replace usage of physical tables in an SQL query.
View 1 Replies View RelatedIs anyone here aware of any explicit/definite differences between running sqlclr on 32-bit and 64-bit.
Note: These must be documented, well defined differences.
I'm having a problem executing a SQLCLR function: this function
calls a web services that processes a query to a data base and
returns a table to be used in a stored procedure. In a low
concurrency scenario (not to many clients connected), the function
returns correctly, however when the concurrency level is increased
we have a SQLCLR command execution problem (all the SQLCLR
processes hangs), making the server unavailable to all web services
processes.
At first we thought the problem could be the SQLCLR, since the web
services is 100% available, all the time. We monitored to come to
this conclusion. Do you know of some SQLCLR bug?
Could someone help me with this? I'm in a difficult situation with
my client, considering that we defended the MS SQLServer technology
and now it's not working properly.
I'll keep trying new threads here... sooner or later, I'm sure an expert Microsoft CLR employee will gladly lend a helping hand!
The pieces:
1. SQL 2005, MS Windows Server 2003, Standard Edition, SP 1
2. .NET 2005/C#
3. Instance of SQL 2005 running locally.
Trigger on local SQL2005 DB table INSERT calls 2 CLR Functions:
1. Retrieve data from SQL2005 DB table and populate local DBF through OLEDB
2. Call external 16-bit application (written in Clipper) that iterates through local DBF records (added from step 1 above) and populates DBF on domain resource.
Step 2 detail:
External 16-bit application is called by CreateProcessAsUser after impersonating token.
THIS IS SUCCESSFUL - IF: I populate SQL2005 DB table using TSQL insert statement. The trigger executes, Step 1 and Step 2 execute perfectly!
THIS IS UNSUCCESSFUL - IF: The SQL2005 DB table is populated by synchronizing SQL Mobile Server database from a SQL Mobile Edition 2005 PDA emulation. The trigger executes. Step 1 executes perfectly. Step 2 executes without exceptions. HOWEVER, the 16-bit application does not execute! Remember, no exceptions. In fact, the result variable returns true from function below:
result = ProcessUtility.CreateProcessAsUser(
hDupedToken,
null,
@"C:MobileDBMobile.exe",
ref sa, ref sa,
false, 0, IntPtr.Zero,
@"C:MobileDB", ref si, ref pi
);
Also, if I Right-click on the Step 2 function in the Server Explorer and click "Execute", it works perfectly. Domain DBF is updated successfully.
So, in short CLR "CreateProcessAsUser" is not doing it's job when the trigger is fired after SQL 2005 DB is populated via replication/sychronization. I would appreciate a response... Thx!
Hi,
My .NET SQL UDF needs do very complex computation on every call regardless on user input. I would be very happy if I could cache this computed data somewhere in SQL Server memory. And then I should not need to recompute this complex information on every UDF call. Is it possible to cache something inside SQL Server from CLR ?
Thanks.
I'm personally in favor of using the SQL CLR where appropriate, although I'm wondering what the negative consequences of enabling SQL CLR might be? Its disabled by default within SQL Server 2005 and most likely 2008, so what was the reason behind this ... beyond the fear of the DBA enabling something he might not himself fully understand.
Thanks,
Doug Holland
By using impersonation I am able to push data to network path / old fashioned DBF's. Of course, I must use unsafe. I am unable, however to successfully run a "cmd.exe" process(), even if I populate the Username, Domain and password (with securestring). It authenticates correctly (checked by giving wrong password or bad username). But when it runs (even just a "cmd.exe"), I get an access is denied error...
StreamWriter sw = File.CreateText("C:\Error.txt");
WindowsIdentity clientId = null;
WindowsImpersonationContext impersonatedUser = null;
clientId = SqlContext.WindowsIdentity;
impersonatedUser = clientId.Impersonate();
System.Security.SecureString password = new System.Security.SecureString();
foreach (char c in "secret")
password.AppendChar(c);
Process p = new Process();
ProcessStartInfo si = new ProcessStartInfo("cmd.exe");
si.UserName = "MyName";
si.Password = password;
si.Domain = "MySecretDomain";
si.UseShellExecute = false;
try
{
p.StartInfo = si;
p.Start();
}
catch (Exception ex)
{
//handle the exception here (This exception handler will not handle the exception, but I get a
//Window popup (While executing my CLR!!!)
}
finally
{
sw.Close();
}
The message popup says: The application failed to initialize poperly (0xc0000142). Click on OK to terminate the application. I'm kind of at a loss...
I'm using a Windows 2003 server box with the latest SQL Server 2005, .NET 2.0/2005. Let me know if you need anything else.

I am searching for a way of using SQLCLR to do Bulk Insert/Copy within SQL Server 2005.
I am not permit to use SQL command BULK INSERT with any of text based file csv, or xml etc.
I did tried to use SqlBulkCopy within SQLCLR but failed, the context connection was not allowed, I did also use normal connection string with sa & pwd but no luck.
I understand that I can move bulk insert to a service such as windows, web or WCF but it is not on the card at present.
Is there a way of doing this within CLR, size of bulk is fair about 2000+ rows.
If you have solution, sample or link would be appriciated.
Cheers

Hi,
I have an SQLCLR assembly which is required to connect to a remote WCF service. In order to do this in a host such as IIS you would need to store all your WCF configuration data (endpoints, types etc) in the Web.config or App.config (in a windows forms app). This begs the question: Where do you store configuration data for SQLCLR assemblies?
The System.Configuration assembly is available in the SQLCLR, but this assumes a Web or App config files exists? Does SQL have its own config file that you can keep your settings in which is called when the assembly is running from within the SQL process?
If this is not possible, should I rather be storing configuration data in the database itself?
This particular example relates to WCF configuration but is relevant for assemblies using Enterprise Library which is also config driven.
Any help would be appreciated.

Problem:
I have an sp which start an external process, It is working at my local machine but does not work at remote server.
FACTS:
Local machine has SQLExpress (SQL version) while remote machine has SQL Enterprise ..
SQL service is running under the System Account at both machines..
I have enabled the Sql server Service to interact with desptop, so that it can start a process in GUI mode.
I thin there is something in connectionstring which does not allow the application to connect to server with appropriate rights.
How I can chage this setting .. is it possible to write this info manually..
Please, comments
Thanks
Just wondering which scenarios is suitable to use SQLCLR. Any kind of data access is not recommended I guess. Only things that cannot be easily done in TSQL should be done in SQLCLR but why? Can't those things be done in app layer itself? Scenarios recommended for SQL CLR:
- External data access like filesystem, registry etc
- Complex calculation
- Recursion without data access (this can be implemented with CTE for data access)
If data access with SQL CLR is not recommended why should CLR should be even used and logic reside in database layer.. it makes no sense to me. Any thoughts??
Is there a limit to the number of connections that can be made to the SQLCLR? If so, what is that limit and is it adjustable?
Thanks!
I have just begun to delve into the SQLCLR objects in SQL Server 2005. I have created a simple VB function as a SQLFunction. Here's the code:
Imports System
Imports Microsoft.SqlServer.Server
Partial Public Class UserDefinedFunctions
<Microsoft.SqlServer.Server.SqlFunction()> _
Public Shared Function FileDate(ByVal FilePath As String) As Date
Return FileDateTime(FilePath)
End Function
End Class
The function is run with this T-SQL:
declare @FileDate datetime
select @FileDate = dbo.FileDate('C:setup.bat)
select @FileDate
This works fine, but I had to set the Permission Level of the Visual Studio project to "Unsafe" rather than "External" in order to avoid the following error message:
A .NET Framework error occurred during execution of user defined routine or aggregate 'FileDate':
System.Security.SecurityException: Request for the permission of type 'System.Security.Permissions.SecurityPermission, mscorlib, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089' failed.
Is there any way to avoid having to set the permission level to "Unsafe"? If not, what does "unsafe" mean in terms of overall system security? Is it acceptable to use on an internal LAN?
Thanks,

Hi
I had DTS the Northwind sample database from SqlServer 2000 to 2005. It's went ok and no errors. Then, I created a SP named upGetCustomer, bascially it queries the Customers table and list some of it's fields and order by CustomerId,CustomerName, Country decrementally. SP is so simple and has no errors.
Then, I created a SqlServer project in VS2005 using C#. Add store procedure class as below,
using System;
using System.Data;
using System.Data.SqlClient;
using System.Data.SqlTypes;
using Microsoft.SqlServer.Server;
public partial class StoredProcedures
{
[Microsoft.SqlServer.Server.SqlProcedure]
public static void Customers(string customerid)
{
using (SqlConnection sqlConn =
new SqlConnection("context connection=true"))
{
sqlConn.Open();
SqlPipe sqlPipe = SqlContext.Pipe;
SqlParameter param = new SqlParameter("@custId", SqlDbType.VarChar, 5);
param.Value = customerid;
SqlCommand sqlCmd = new SqlCommand();
sqlCmd.CommandType = CommandType.StoredProcedure;
sqlCmd.CommandText = "upGetCustomer";
sqlCmd.Parameters.Add(param);
SqlDataReader rdr = sqlCmd.ExecuteReader();
SqlContext.Pipe.Send(rdr);
}
}
I had taken method of created SQLCLR from source in Microsoft website, but coding is mine, and hopes it is correct. I used SqlConnection string as 'context connection=true' which I still not quite sure what does it means, hopes it mean current connection I am using on my Windows authentication.
The project did compiled & deployed OK on the VS2005 side.
The problem is that when I tried to locate the assembly on the Sql Server 2005, but can't find it anywhere on Sql Server.
I did try complied and deloyed again, it keeps saying there is an error in deployment as customers assembly is already exist on the database. I then, tried to remove this assembly on the database using SQL script, drop assembly customers in the Northwind database but got error saying it does not exist. So where is it???
Please help...
Thank you
I keep getting different answers from different people on regarding if you can or cannot kill the hosting sql server process with an unsafe assembly. Can you do this? If so could you please attach a sample demonstrating this?
Thanks,
Derek
Throughout the course of this book and even before it I have come across conflicting information regarding how SQLCLR attempts to resolve system/CLR assembly references. For example, prior to my latest read thourgh April BOL 2005, I thought SQLCLR attempted to resolve these references implicity for you via the local machine's GAC. Yet here is what I found while trying to help another person in this forum yesterday in BOL...
Assembly Validation
SQL Server performs checks on the assembly binaries uploaded by the CREATE ASSEMBLY statement to guarantee the following:
The assembly binary is well formed with valid metadata and code segments, and the code segments have valid Microsoft Intermediate language (MSIL) instructions.
The set of system assemblies it references is one of the following supported assemblies in SQL Server: Microsoft.Visualbasic.dll, Mscorlib.dll, System.Data.dll, System.dll, System.Xml.dll, Microsoft.Visualc.dll, Custommarshallers.dll, System.Security.dll, System.Web.Services.dll, and System.Data.SqlXml.dll. Other system assemblies can be referenced, but they must be explicitly registered in the database.
For assemblies created by using SAFE or EXTERNAL ACCESS permission sets:
The assembly code should be type-safe. Type safety is established by running the common language runtime verifier against the assembly.
The assembly should not contain any static data members in its classes unless they are marked as read-only.
The classes in the assembly cannot contain finalizer methods.
The classes or methods of the assembly should be annotated only with allowed code attributes. For more information, see Custom Attributes for CLR Routines.
Besides the previous checks that are performed when CREATE ASSEMBLY executes, there are additional checks that are performed at execution time of the code in the assembly:
Calling certain Microsoft .NET Framework APIs that require a specific Code Access Permission may fail if the permission set of the assembly does not include that permission.
For SAFE and EXTERNAL_ACCESS assemblies, any attempt to call .NET Framework APIs that are annotated with certain HostProtectionAttributes will fail.
COULD SOMEONE PLEASE GIVE ME THE DEFENITE ANSWER ON HOW THIS WORKS!
Hi,
I've got a requirement for a procedure to write a text file and want to do it without using command line utilities.
I wrote a sqlclr which queries a db and writes the file that I need. After setting the external_access and database to trustworthy, It only works on my own machine, not on network shares.
Some threads I've found have been related to the "1 network hop" of Windows credentials, which most of us are probably familiar with.
It doesn't make sense to me that this is the problem, since I'm on my workstation, connecting to a local db instance and hopping one time to the shared server. Anyone know what the cause might be?

I am trying to generate a SQL CLR stored procedure and i have done it too. Now the next step is to convert that *.dll file in to assembly. I am getting erro that. My server Database is on the LAN, not on my PC.
Here is the code which i have tried to register an assembly...
/*
CREATE ASSEMBLY MyAssembly FROM 'C:Documents and SettingsAdministrator.ORC80My DocumentsVisual Studio 2005ProjectsMyDB1MyDB1inDebugMyDB1.dll'
WITH PERMISSION_SET=SAFE

*/
and here is the error that i am getting...
/*

*/
Please help me .I am stuck at here.
Hi all,
The problem is: when you're trying to call in method MyMethod anonymous method that doesn't use local variables, deployment of the assembly will fail referring that MyMethod tries to store smth. in the static variable. Indeed, looking at the compiled CLR code, you can see that anonymous delegate is cached in the private static delegate and the call looks like:
If(ClassName.privateStaticDelegate == null)
ClassName.privateStaticDelegate = new MyDelegate(HiddenMethodName);
CallAnonymousMethod(ClassName.privateStaticDelegate);
Is there any workaround to fix this problem.
P.S. I googled about this problem and found only one article on it:
http://www.ayende.com/Blog/default,date,2005-12-26.aspx
CREATE ASSEMBLY uploads an assembly that was previously compiled as a .dll file from managed code for use inside an instance of SQL Server.
What I want to do here is enable/create a "MODIFY" option on CLR-based objects in Object Explorer.
Option is only supported for assemblies who's source code has been previously loaded into DB via ALTER ASSEMBLY
Upon electing the option, source code gets displayed in editor.
Users alters managed source
User clicks the "Execute" button in the editor
onClick of "Execute" performs following
Alters managed source (not sure if this can be done in the system tables, may have to save .cs/.vb files out to file system first then reupload)
Builds updated source/.dll is built
Executes an ALTER ASSEMBLY statement to "refresh" the dll and it's associated source code file(s)
Now...how the heck do i do this lol! Anyone
Hello,
I have a sqlclr stored procedure that works well if started via execute in SSMS. (The stored procedures makes a SSRS web service call.) When I install a trigger on a database table to execute the stored procedure
create trigger NewWdsStatsEntry on dbo.WDSSTATS after insert
as execute UpdateReportExecutionSnapshot N'http://localhost/ReportServer/reportservice2005.asmx', N'/Report1';
go
and add something to the table, I get the following error:
Msg 6522, Level 16, State 1, Procedure UpdateReportExecutionSnapshot, Line 0
A .NET Framework error occurred during execution of user-defined routine or aggregate "UpdateReportExecutionSnapshot":

The statement has been terminated.
The insert times out after 100 seconds and no row has been added to the table, but the web service call actually created a new report! Any idea why the trigger can't execute the stored procedure?
Thanks!

I can create an external text file from within the SQLCLR project, but I cannot run an external executable. Just in case you are asking, I need to do this to push data into a legacy application using a different DB format. I have found it best to simply use my old language (Clipper) for data validation, etc. - and especially since I require multiple indices to be open. So, if you could just take my word on this.
The following code:
Process newProcess = new Process();
string path = @"C:TEST.BAT";
newProcess.StartInfo.FileName = path;
newProcess.Start();
Executes without error, but does not actually run the external.
Now, I can have a DOS (Clipper) application poll a directory for text files, but I am trying to get away from all these "mini" data transformation applications. If an exception is caused in the DOS app, a remote user on the other side of the country has no idea it is broke and his data (coming from a SQL Mobile Device) never gets to our legacy database structure.
So, am I out of luck?
I expected Optional ByRef nArg as Integer=123 to setup a sp arg with a default value of 123. Doesn't look like it does. Anybody know what I'm doing wrong?
Also, I can't write a function with a return using AS System.Int32. There is no RETURN sp arg.
Both situations compile/deploy without error.

This same code works just fine when not running in the SQL CLR assembly. The assembly is marked as External, but I've also tried marking it as Unsafe, which did not work either.
Any suggestions on what the problem might be or how to troubleshoot this further would be greatly appreciated.
Thanks,

have done several SQL_CLR stored procs.
on one of them, get an intermittent error
Msg 6532, Level 16, State 49, Procedure clrsp_RetailPriceOnDate, Line 0
.NET Framework execution was aborted by escalation policy because of out of memory.
System.Threading.ThreadAbortException: Thread was being aborted.
System.Threading.ThreadAbortException:
at Data_SQLCLR.StoredProcedures.clrsp_RetailPriceOnDate(SqlInt32 iSQLsysid_Individual, SqlInt32 iSQLStore, SqlInt32 iSQLGroup, DateTime dtPriceDate, SqlInt32 iSQLInclude)
Msg 6532, Level 16, State 49, Procedure clrsp_RetailPriceOnDate, Line 0
.NET Framework execution was aborted by escalation policy because of out of memory.
Problem is that it is intermittent - runs fine several times(takes c 30 secs to run, returns 15k records), then fails, then runs ok, fails/runs/runs/fails etc... etc...
any ideas on how to track / catch this one
thx
