Consuming A Recordset In A Script Transformation
Nov 3, 2006
I have a situation where I have created a recordset in a previous data flow task where the output was a recordset.
Now I want to write that recordset to a flat file.
There is no direct recordset input data flow source. So I thought I would use a source script transformation to read the recordset. Then I searched on this and found no information on how I might do this.
Anyone have any ideas on how to do this in a script transformation?
There are reasons that I would like to do it this way, but if I have to choose another way, well that's life.

Hi,
If you have two synchronous transformation components and the input of the second is connected to the output of the first, does the first transformation process (loop through) all rows in the buffer before outputting these rows to the second transformation? Or does the first transformation output each individual row to the second transormation as soon as it has finished processing it?
Thanks in advance,
Lawrie.

tell me the difference between Audit transformation and rowcount transformation.
Because audit and rowcount transformation will provide the environment variables.
Only difference i am finding is rowcount returns the count of rows its updating .
Apart from these is there any other difference?
Tell me the scenario where i need to use the audit transformation.

I've just faced quite interesting case.
I have two SQL Servers 7.0 running on two W2K(sp1) Server boxes (Compaq ProLiant 1600 and HP NetServer LC3) both with RAID5. One of the task these servers peform is logging MS Proxy.
For more convenient way I created the procedure that show me proxy users, their IP address and URL head where they hit for the last one minute and half. This one as follow:
-----
REATE proc usp_showusers as
select clientip, clientusername, substring(stuff(uri, 1, 7, ''), 1, patindex('%/%', stuff(uri, 1, 7, ''))) short_uri into #whoweb from msplog where logtime > getdate()-0.001
select clientip, clientusername, short_uri from #whoweb
group by clientip, clientusername, short_uri
-----
So, when I run this proc on HP box it executes well and SQL keeps on consuming the same amount of memory (approximately 60MB)
When I run on Compaq, the proc executes well as well, but promptly gets memory consume up to 150MB (before execution it did ~50(60)MB). In half an hour it pulls down 90MB.
In addition to SQL Server the boxes run Lotus Domino R5 and Active Directory.
The installed software on them is absolutely identical.
Any idea? I'd be really appreciated.
Thanks

Hi there,
I've been following Vineets and David's procedures to consume web
services using SQL CLR to the t. I created my web service in C#.NET
2005, and generated my proxy using this command:
wsdl /par:oldwsdlconfig.xml /o:ExactMobileService.cs /n:Project360.SmsService http://www.exactmobile.co.za/interactive/interactivewebservice.asmx
I added both files to the project, set Generate Serialization Assembly to on and compiled it.I then generated a strong name key for the assembly and signed my assembly with that key.Inside my post-build event I added the following script:
"E:DevelopmentMicrosoft
Visual Studio 8SDKv2.0Binsgen.exe" /force
/compiler:/keyfile:SmsServiceKey.snk /t:StoredProcedures
$(TargetDir)$(TargetName).dll
This compiled into my assembly, the XmlSerializer assembly and then added strong name key to both.
In SQL Server 2005, I enabled CLR, made my DB trustworthy, created my
first assembly with permissions EXTERNAL ACCESS and then the
XmlSerializer assembly with permissions SAFE. I created my stored
procedure and ran it. When I did I got this error which I assumed the
XmlSerializer was supposed to solve for me:
System.InvalidOperationException:
Cannot load dynamically generated serialization assembly. In some
hosting environments assembly load functionality is restricted,
consider using pre-generated serializer. Please see inner exception for
more information. ---> System.IO.FileLoadException: LoadFrom(),
LoadFile(), Load(byte[]) and LoadModule() have been disabled by the
host.
I have seen alot of posts about this error, but none of them has been able to solve my problem.
Please can you help me?

Hi,
We've been using Sql Server 2005 for some time now and we've found it to be stable and pretty much bug free, well done! (as opposed to Oracle 10g, which is bug-ridden) I'm not sure if this is the right forum to post this in, but it felt like the best place to start. Please move my post if it is not correct.
In the last few weeks we've had a very serious problem; whenever we try to execute our upgrade scripts the CPU usage spikes to 100%. And then every insert takes > 0.5 seconds. Needless to say, but I'll do it anyway, this is a huge problem. Some of our scripts have > 100 000 inserts, so the upgrade process takes "forever".
At this point it might be useful to talk just briefly about how we use our Sql Server; We have an application that is configured via the database (we support Sql Server and Oracle) and so we use the database for a lot more than just a "dumb" datastore. We do massive amounts of insert/update for every version of our application and we add new tables quite often. We have a build system, using TFSBuild, where we do nightly builds. That build will drop the current database (example of name: MONDAY, TUESDAY etc.) and restore it again using an image. Then we upgrade the new database to the most current version of our scripts. On our Sql Server 2005 server we have 4 such databases so the process is repeated 4 times each night. And since we build our database using a baseline image and scripts (both stored in source control) we do not need backups of the databases, so no backup plan is running. I'm only mentioning that because we've had a theory that this might be the cause of our problems...
So, does anybody have an idea how we might go about solving this?

Hi,
Ive been taking a look at how to consume events from a package when executing programatically.
Ive got some code (copied below) that creates a package programatically, adds a sequence container then within that adds a script task , then executes it using the overloaded method of Package.Execute() that takes an IDtsEvents argument.
My class that implements IDtsEvents simply output a message to the console for each event type.
Weird thing is, when I execute, this is the only output I get:
Starting...
OnPreValidate: Microsoft.SqlServer.Dts.Runtime.Package
OnPreValidate: Microsoft.SqlServer.Dts.Runtime.Sequence
OnPreValidate: Microsoft.SqlServer.Dts.Runtime.TaskHost
OnPostValidate:Microsoft.SqlServer.Dts.Runtime.TaskHost
OnQueryCancel
Package ran successfully
What I find weird is that I dont get information for loads of other event types. I would at least have expected to see some OnPostExecute events.
Anyone know why i dont see all of the events?
Thanks
Jamie
Heres the code:

p.OfflineMode = true;
// Add a Script Task to the package.
Sequence s = (Sequence)p.Executables.Add("STOCK:Sequence");
TaskHost taskH = (TaskHost)s.Executables.Add("STOCK:ScriptTask");
// Run the package.
DtsEvents events = new DtsEvents();
p.Execute(null,null,events,null,null);
//p.Execute();
if (p.ExecutionResult == DTSExecResult.Failure || p.ExecutionStatus == DTSExecStatus.Abend)
Console.WriteLine("Package failed or abended");
else
Console.WriteLine("Package ran successfully");
Console.ReadLine();

Hi:
Can someone help me with a SSIS package that would consume from a Web Service (in fact two of them) and then load the data into SQL Server. I currently have Web Service task which connects to ForEachLoop task, and inside the loop task, I have a DFT. I am thinking, I would need to call the webservice utilizing the Web Services Task, and then store the output in a Full ResultSet variable. In my loop, I would like to loop thru the resultset, and store the data into SQL server. Inside the DFT, how would I construct this mechanism? Also, is this a good way to consume from a Web Service and then populate SQL Server? Are there any alternate ideas on this? Any documentation on this yet? Thanks.

Hi,
I believe this question has been covered quite a bit, but none the less I wanted to ask it as I still have no resolution at the moment. I am consuming a table from Oracle which has a data type of NUMBER. When I use a .Net Provider to consume the data, the SCALE defaults to 0 for these select columns and thus we lose any decimal point information for these columns. I have tried using both the .Net Provider and the .Net for OLEDB providers for ORACLE. Both seem to suffer from this. The SSIS server itself is a Win 03' server on x64 hardware architecture. Also, when trying to use the Oracle Provider for OLEDB it throws a design-time error stating "Error in Initializing Provider".
Thanks!

Dear All,This is a query surrounding a problem I encounteredyesterday.In SQL Server, it is possible to write a procedure thathas one or more select statements in it.The results from these select statements will all beindividually returned to SQL Query Analyser where theycan be viewed in "grid" views. Also, these individualresults sets can be consumed by eg ADO.NET by steppingthrough each results set in turn and processing therespective results.My question is, can you do the same in a SQL Serverprocedure? ie:Create Procedure Proc1ASbeginselect Col1, COl2from Table1select Col1, Col2, Col3from Table2endCreate Procedure Proc2ASbeginexec Proc1endCan both/either of the results sets from Proc1 beconsumed by the calling procedure Proc2?I can see that you could design the procedures up-front to do almost anything without consuming theresult sets in this way, but if the proceduresreturning the results sets are already built andin use in other places (for instance in client code),can they be re-used on server-side SQL procedures?Thanks in anticipation!Paul.

Assume I've created a web service named 'SaveActivityData' for some SQL 2005 database on some remote server. Also assume that the stored proc takes two parameters; the first is an integer value and the second an XML value.
1) Is it possible for a stored procedure on a completely different SQL 2005 server to consume this web service?
2) If the above is possible, could someone show me an example of the T-SQL syntax required to consume this web service, passing the two required parameters? In your example, you can make up whatever URL you like for the remote web service location.
Thanks very much - Amos.

At first the server is busy to process the request, when the server is done the rendering client side takes 100% of CPU and never displays the result ("IE is not responding").

Hi,
I have created a program that imports a csv into the sql server. but during that import I need to track all the errors that occured for some malformed rows. I think I need to use the error output collection of the dataflow components to track the errors. I figured out that every dataflow component has a error output collection along with the data output collection. I want to write those error outputs into a separete database. So, I have created a SQL server data destination component and created a path between derived columns error output and it input collection. But it is not working as expected. can any body help on this?
or can anyone give me any example how to use/handle error output collection in SSIS?
I will appreciate all kind of suggestions.

Hi,
Need a guidance on consuming the WCF service with complex type in the SSIS package.
I have a WCF service with complex type inside the complex type (Nested complex type) in the web method as an argument. When I try to use this WCF service in the SSIS web service task, I get an error "The web method has unsupported arguments".
I am able to consume the WCF service with the web method having Complex type and simple/prmitive type in side that as argument.
For example:
The web method in WCF service which accepts the argument as comlex type say "Employee" whose structure is:
Employee
{
FName String;
LName String;
Age int
}
It is possible to consume this WCF service and pass the arguments.
But when the Employee complex type is changed to have one more complex type in side it it give the above mentioned error. The Employee type is modified as:
Employee
{
FName String;
LName String;
Age String
Type EmployeeType;
}
EmployeeType
{
type string;
}
Now I get the error Web Method has unsupported arguments.
Can this be done in SSIS?

Hello All,
I’m looking for a solution to timeouts that occur when I’m executing a stored procedure from my web application. Most of the SPs will run from 3 to 15 minutes, and, unfortunately, modifying/optimizing them isn’t an option at the moment. I tried setting the CommandTimeout to 0 with no luck. Unless, I didn’t use it properly. Here’s my code: 1
2 try
3 {
4 string dbConn = ConfigurationManager.ConnectionStrings["ConStringNTMTLDEV"].ToString();
5 OleDbConnection connection = new OleDbConnection(dbConn);
6
7 lbl_SearchResult.Text = dbConn;
8
9 //OleDbDataAdapter adapter = new OleDbDataAdapter();
10 OleDbCommand cmd = new OleDbCommand("SP_CallHistoryLookUp", connection);
11 cmd.CommandType = CommandType.StoredProcedure;
12
13 cmd.Parameters.Add(new OleDbParameter("@phoneNumber", "1234567890"));
14 cmd.Parameters.Add(new OleDbParameter("@email", "123@123.com"));
15 cmd.Parameters.Add(new OleDbParameter("@WebUser", "123"));
16 connection.Open();
17 cmd.CommandTimeout = 0;
18 cmd.ExecuteNonQuery();
19 cmd.Dispose();
20 connection.Close();
21 }catch(OleDbException ex)
22 {
23 lbl_SearchResult.Text += "<br/> Something went wrong </br>";
24 lbl_SearchResult.Text += ex.Message.ToString();
25 }
26

Is it possible to launch a stored procedure and close the connection without waiting for a result?Would the stored procedure still run on the SQL server? I’m using MSSQL 7. Would you have any examples that would solve this problem? Thank you for your help.

Hi, I have a scenario in which an application generates events upon updates to the database, which need to be reliably transmitted to consuming applications running a) other SQL Server instances and b) as remote web services.
Now,
1) I am planning to use SQL Server Notification Services to generate these events, and allow the consuming applications to subscribe to them.
2) The events will be sent to a ReceiveEvent service, which will then process the event and put it in the respective queues for the Subscriber (consumer) applications.
3) The services representing these consumer applications will then get activated, and sent the message across directly to the service broker on the consumer side in case of situation a - where there is a SQL Server on the other side
4) In case the other side is a web service, I plan to make a SOAP request directly from my queue handler, and depending on the response received, decide whether to commit or roll back that particular transaction.
Does this seem like a good solution? I am very new to the Service Broker, and I am still getting my hands dirty. Any comments/suggestions would be very highly appreciated!
Regards,
Siddhesh

Hello All,
After hitting limitations in the SQL CLR world that bar us from invoking COM objects we are forced to use windows services to read the messages off the Service Broker Queues.
Unfortunately we loose the auto activation feature in the Queues, but we can still read messages and perform the SQL work under one transaction.
We are going to attempt to take N messages simultaneously from the Queue, though N instances of a windows service. If the messages send to the queue are one message per conversation, will we be able to achieve having N readers take messages off simultaneounsly?
Thank you very much,
Lubomir
P.S. if anyone has a better approach to obtaining the message in "out of sql code" or invoking external (not assemblies stores in SQL server) code libraries, that would be etremely nice to hear. I have thought about invoking a web service through CLR, but that is probably too much overhead - MSMQ seems much more appealing than a web service;

form I have 2 command buttons:one gives me the article's definition(Date,Source)
and the other gives me the Filename of the current recordset(Article)
The above SQL syntax is it correct?

Here's my SQL Statement (I'm using MS SQL 2000):
SELECT TOP 2 MenuComments, MenuDate, MenuID, MenuIsActive, MenuName
FROM Menu
ORDER BY MenuDate DESC
This orders the data correctly, but the problem is, I need ONLY the SECOND row, not the top row. Also, because I am sorting for menus entered into the system, I cannot use a variable based on real dates (in other words, I can't use the server clock to help filter the results).
Any and all help would be GREATLY appreciated -- I've been banging my head against this one all day!

Hi,
I am using classic ASP.
Records are grouped together by a GroupUnique number. Some groups are small with about 10 records, othere are larger at about 160.
For each record, I have about 50 columns of data that I need to display on a webpage. Because the 50 columns don't easily fit on the one page, I create two tables, each displaying 26 columns, the first columnn being an ID column. Due to the size of groups, sometimes the tables are very large - and when they get too big it overloads the server.
I think the main problem is the two tables. I use two recordsets (one of them is shown below - although instead of a SELECT * I do in fact name the columns needed for each table). I have to use two because the Recordsets don't like me using the ID column again - once it is used it is gone.
Is there a better way to store all of this information so that I can just use the one recordset? Possibly in an array? Is there a more efficient way of getting the data?
<%
Dim Recordset4__MMColParam1
Recordset4__MMColParam1 = "1"
If (Scramble.Fields.Item("GU").Value <> "") Then
Recordset4__MMColParam1 = Scramble.Fields.Item("GU").Value
End If
%>
<%
Dim Recordset4
Dim Recordset4_numRows
Set Recordset4 = Server.CreateObject("ADODB.Recordset")
Recordset4.ActiveConnection = conn
Recordset4.Source = "SELECT * FROM Table1 WHERE GroupUnique = " + Replace(Recordset4__MMColParam1, "'", "''") + ""
Recordset4.CursorType = 0
Recordset4.CursorLocation = 2
Recordset4.LockType = 1
Recordset4.Open()
Recordset4_numRows = 0
%>
<%
Dim Repeat4__numRows
Dim Repeat4__index
Repeat4__numRows = -1
Repeat4__index = 0
Recordset4_numRows = Recordset4_numRows + Repeat4__numRows
%>
