I have several fuctions that I would like to share between my different script tasks in my SSIS package. I assume I do this by creating a custom class, but I cant quite figure it out. Can someone please point me in the right direction?
Thank You!!
Hello everybody,
I am new to .NET programming and the C# language. I'm coming from a ColdFusion/Java background, but am trying to learn .NET to further my abilities as a programmer, and take advantage of the CLR functionality in SQL Server.
What I am wondering is: is it possible to write an assembly which has stored procedures and functions that each utilize a custom class written within that assembly?
I am having some trouble with this concept. I am writing a UDF that will compile various data together and build a string from it. To help simplify the code, I want to build a custom class which will represent the primary object I am running the compilations against.
I would like to have the class be able to load its data directly from the database using a load() method. However, I am getting the following error when trying to run the UDF:
Msg 6522, Level 16, State 2, Line 1
A .NET Framework error occurred during execution of user defined routine or aggregate 'CompileList':
System.Security.SecurityException: Request for the permission of type 'System.Data.SqlClient.SqlClientPermission, System.Data, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089' failed.

Any help and/or insight would be greatly appreciated.
Thanks,

I have a custom assembly that i'm trying to get tied into my report. the problem is when i try to call it i get the error that the class is not defined
I have the class in the references tab and the class name and instance name both have a name.
here's the error I'm getting
Error 1 [rsCompilerErrorInClassInstanceDeclaration] Error in class instance declaration for class Assembly_1: [BC30002] Type '[ClassName]' is not defined. [Project folder][reportname].rdl 0 0
I have OLE DB Connections set up in my connection manager (Native OLE DBMicrosoft OLE DB Provider for SQL Server). I would like to reference and query these connections from a custom task, written in C#. I currently reference it as follows:
using System.Data.OleDb;
...................................
OleDbConnection connection = (OleDbConnection) connections["MyConnection"].AcquireConnection(null);
What may be obvious to some (though wasn't to me, as I am new at this), when I run the task, I get an error saying that I cannot make this cast. After perusing the boards, I understand that this is because I am not making a cast to the right connection type. Well, that is where I am lost. What connection type (and corresponding library) do I need to reference? I want to continue to use the "Native OLE DB..." connection.
Thanks!
Good Morning..
We're having a heck of a good time trying to implement our first CDE project in SSRS 2005.
In our SDE class library we have included an App.Config file where we want to store configuration settings..
Trouble is that when we view the configuration settings or connection string settings in debug mode, they're not being read for some reason..
Here's our app.config file:
-------------------------------------------------------------
<?xml version="1.0" encoding="utf-8" ?>
<configuration>
<configSections>
</configSections>
<appSettings>
<add key="eventLogName" value="FocusDPEEventLog" />
</appSettings>
<connectionStrings>
<add name="PassConnString" connectionString="Data Source=SOMEDATASOURSE;Persist Security Info=True;User ID=SOMEUSERNAME;Password=SOMEPASSWORD;Unicode=True"
providerName="System.Data.OracleClient" />
</connectionStrings>
</configuration>
-------------------------------------------------------------
Here's what our Immediate window Debugger is tellin' us about our configuration settings:
-------------------------------------------------------------
ConfigurationManager.AppSettings
{System.Configuration.KeyValueInternalCollection}
[System.Configuration.KeyValueInternalCollection]: {System.Configuration.KeyValueInternalCollection}
base {System.Collections.Specialized.NameObjectCollectionBase}: {System.Configuration.KeyValueInternalCollection}
AllKeys: {Dimensions:[0]}<----incorrect should be 1
ConfigurationManager.ConnectionStrings
Count = 1 <----ok, is one, but the wrong 1, see 3 lines down...
base {System.Configuration.ConfigurationElementCollection}: Count = 1
ConfigurationManager.ConnectionStrings[0]
{data source=.SQLEXPRESS;Integrated Security=SSPI;AttachDBFilename=|DataDirectory|aspnetdb.mdf;User Instance=true}<--Should be PassConnString
base {System.Configuration.ConfigurationElement}: {data source=.SQLEXPRESS;Integrated Security=SSPI;AttachDBFilename=|DataDirectory|aspnetdb.mdf;User Instance=true}
ConnectionString: "data source=.\SQLEXPRESS;Integrated Security=SSPI;AttachDBFilename=|DataDirectory|aspnetdb.mdf;User Instance=true"
Name: "LocalSqlServer"
ProviderName: "System.Data.SqlClient"
Now notice the stuff in bold...I have NO IDEA where this gosh-danged thing is reading, but it doesn't seem like it's the app.config file in our class library...
thanks..

Hi,
Can anyone tell me where I might find the Class and Sequence Diagrams for the SSIS framework (for Custom Components)?
I've just started trying to create some Custom Transform Components and
I'm really struggling to get my head around the component lifecycle
(i.e what methods are called when, with what arguments, and why) with
just the BOL documentation to guide me.
Thanks in advance,
Lawrie
I have a requirement in which i have to create a custom .net class library for Ex:-I retrieve password(s) from a thrid party component. Below is what i am doing.
(1) Created a custom class library which reads a custom .xml file from a drive Ex:- "D:MyAppMYAppCofig.xml" and sets to my properties of my custom class library and inside it i created an instance of third party component's class and passed these values. Since i need to use this .net custom class library both in web and ssis/database side i am using this custom .xml file.
(2) After validating passed data (properties set in custom .net class library) the thrid party component instance object created in my custom .net class libraty returs a password to me own custom .net class libray.
(3) This password I use in my web app for connecting to database. This code is working fine.
(4) My question is how to execute a custom .net class library code through ssis and to use the my same custom .net class library and pass the password to my SSIS component / taks so that that code block also uses the returned password to connect and do any needed tasks? In other words how to use custom .net class library from SSIS.
My Environment is as follows:-
SQL Server is : 2008 R2
VS.NET 2013
I have a SqlDataSource that has a parameter that I am trying
to set.
The item is stored in a session field called “GameObject�
Game Object is a simple class that has a several variables.
I am trying to access the .name data member of the class.
<asp:SessionParameter Name="GameCode" SessionField="((GamingSystem)Session[‘GameObject’]).Name" />
This does not work. Is there a way to declarative bind to
the item that I am for.
Hai Guys,
I have a doubt Regarding SqlDataReader
i can able to create object to Sqlconnection,Sqlcomand etc...
but i am unable to create object for SqlDataReader ?
Logically i understand that SqldataReader a way of reading a forward-only stream of rows from a SQL Server database. This class cannot be inherited.
sqlDatareader belongs to which class is it sealed or static class?
can we create own class like SqldataReader .......
Reply Me ...... if any one know the answer..............
We have a static class that makes an HTTPWebRequest to get XML data from one of our vendors. We use this as input to a stored proc in SQLServer2005. When I compile this class and call it from a console application in visual studio it executes in milliseconds, everytime. When I compile it, create the assembly and clr function and execute it in SQLServer, it takes around 14 seconds to execute the first time, then on subsequent requests it is again really fast, until I wait for 10 seconds and re-execute, once again it is slow the first time and then fast on subsequent requests. We do not see this behavior when executing outside SQLServer. Makes me think that some sort of authentication is perhaps taking place the first time the function is run in SQLServer? I have no idea how to debug this further. Anyone seen this before or have any ideas?
Here is the class:
Code Snippet
using System;
using System.Collections.Generic;
using System.Text;
using System.Net;
using System.IO;
namespace Predict.Services
{
public static class Foo
{
public static string GetIntradayQuote(string symbol)
{
string returnQuote = "";
HttpWebRequest request = (HttpWebRequest)(WebRequest.Create("http://data.predict.com/predictws/detailed_quote.html?syms=" + symbol + "&fields=1,2,3,4,5,6,7,8,9,10,11,12,13,14,15,16,17,18,19,20,21,22,23,24,25,28,30"));
request.Timeout = 1000;
HttpWebResponse response = (HttpWebResponse)(request.GetResponse());
StreamReader streamReader = new StreamReader(response.GetResponseStream());
returnQuote = streamReader.ReadToEnd();
streamReader.Close();
response.Close();
return returnQuote;
}
}
}
When I run call it from a console app it is fine.
I compile it into a dll and then create the assembly and function as follows:
Code Snippet
drop function fnTestGetIntradayQuoteXML_SJS
go
drop assembly TestGetIntradayQuoteXML_SJS
go
create ASSEMBLY TestGetIntradayQuoteXML_SJS from 'c:DataBackupsCLRLibrariesTestGetIntradayQuote_SJS.dll' WITH PERMISSION_SET = EXTERNAL_ACCESS
go
CREATE FUNCTION fnTestGetIntradayQuoteXML_SJS(@SymbolList nvarchar(max)) RETURNS nvarchar(max) AS EXTERNAL NAME TestGetIntradayQuoteXML_SJS.[Predict.Services.Foo].GetIntraDayQuote
go
declare @testing nvarchar(max)
set @testing = dbo.fnTestGetIntradayQuoteXML_SJS('goog')
print @testing
When I execute the function as above, again, really slow the first time, then fast on subsequent calls. Could there be something wrong with the code, or some headers that need to be set differently to operate from the CLR in SQLServer?
Regards,
Skipper.
In MS Access, I could write a function in a module, then just call that function as part of the SQL statement. For example, "SELECT RemoveDashes([SS_No]) AS SSN FROM Employee" with "RemoveDashes" being the name of the function.
I'm trying to do the same with an asp.net page and sql server. I have a custom function in the code behind that I call in the SQL statement, but I get the error, "not a recognized function name".
What do I need to do to make this work?
All help is greatly appreciated!

I made an SQL function in MSSQL2000. This is a function that get's a calculated heat emission. When I run the Query in MSSQL2000 the function works. It calculates every emission for every row. When I call this SQL function in VS2005, it says it does not recognize the function. Does anyone know what this may cause? thank you. For the people who are bored, I added the SQL statement. The error is at the function
SELECT TOP 15 tbProducts.prod_code, tbProductProperties.prop_height, tbProductProperties.prop_length, tbProductProperties.prop_type, tbProductProperties.prop_default_emission, tbProductProperties.prop_weight, tbProductProperties.prop_water_volume, tbProductProperties.prop_n_value, GetHeatEmission(50,70,20,[prop_default_emission],[prop_n_value]) AS customEmission FROM tbProductClassification INNER JOIN tbProducts ON tbProductClassification.clprod_fk_prod_id = tbProducts.prod_id INNER JOIN tbProductProperties ON tbProducts.prod_id = tbProductProperties.prop_fk_prod_id WHERE (tbProductClassification.clprod_fk_class_id = 3327) AND (prop_height >= '030') AND (prop_height = '060') AND (prop_length

Greetings,
I need to create a function that is available across all databases. This function is for exchange rate conversions and will be used extensively. I'd prefer not having to call it by it's full four-part name and just make it available everywhere on the server.
Is there a way to create such a function? Where is it stored?

Hello, I am about out of hair from pulling it out. If someone could please show me what I'm doing wrong I would really appreciate it. I have this function for a SSRS 2005 report:
Public Function funAdditions(pFields As Fields) As Double
if pFields !FA00902_AMOUNT.Value > 0 and
pFields !FA00902_TRANSACCTTYPE.Value = 3 and
pFields !FA00902_DEPRTODATE.Value > Parameters!BeginDate.Value and
pFields !FA00902_DEPRTODATE.Value <= Parameters!CutOffDate.Value and NOT
instr(pFields !FA00902_SOURCDOC.Value, "FACHG")=1
then return pFields !FA00902_AMOUNT.Value
end
else if pFields !FA00902_TRANSACCTTYPE.Value = 3 and
pFields !FA00902_DEPRTODATE.Value > Parameters!BeginDate.Value and
pFields !FA00902_DEPRTODATE.Value <= Parameters!CutOffDate.Value and
instr(pFields !FA00902_SOURCDOC.Value, "FACHG")=1
then return pFields !FA00902_AMOUNT.Value
end
End Function
...and after much research cannot figure out the solution to this error:
[rsCompilerErrorInCode] There is an error on line 1 of custom code: [BC30201] Expression expected.
I'm new to SSRS so is there a syntax error I'm missing?
Thanks in advance,

I want to create a custom bitwise OR aggregate function.
I want to use it like the built in aggregate functions (MIN, MAX etc.)
SELECT dbo.bitwise_or(bit_string) FROM table
where bit_string is a nvarchar(3)
so for example if the table contains two rows ('100', '001') the above query should return '101'
I would like to implement this as a CLR function/assembly with the aggregate below:
CREATE AGGREGATE dbo.bitwise_or (bit_string nvarchar(3))
RETURNS [nvarchar(3)]
EXTERNAL NAME [Aggregate].[bitwise_or]
I have followed this post to implement amedian aggregate function [URL] ..... but there is a lot of code (not sure what is really needed in my case).

This is how I am trying to use it in the View:
Production.GBDATEADD(Production.Schedule.START_DATE, Production.Operations_Data_Pool.MFG_DAY - 1) AS SCH_DATE
I created a custom function that accepts an array of strings as a input. I need to pass several fields from the dataset to this function as an array. How can I do this?

Hi All,I need help in creating a function in VB for my ASP.NET application where I want to add records to database on the first day of every month.I have got no idea about what I have to do for achieving this goal.Its basically for a customer based application where Interest will be paid into customers' account and I need to implement this for every customer on 1st day of every monthThe thing I am not sure about is how can I get the application to add a record for each customer on the first day of each month, i.e. how can I get the application to check that its 1st day of month and then the application adds records automatically for each customer based on my specified rules.If any of you could help me with this, I'll really appreciate it.Thank you.
View 5 Replies View RelatedWhen data is imported from our legacy system, the same functions need to be applied to several columns on different tables. I want to build a kind of "Function Library", so that the functions I define can be re-used for columns in several packages.
The "Derived Column" transform seems ideal, if only I could add my list of user-defined functions to it. Basically I want to inherit from it, and add my own list of functions for the users to select.
Is this possible ?
What other approaches could I take to building about 30 re-usable functions?

Hi there
I'm relatively new to Reporting Services and .Net development so bear with me if I've missed something obvious.
I've set up Reporting Services to run under forms authentication successfully.
I want to filter the data (both within Report Builder Models and .rdl files) to the company the user belongs to.
To avoid joining the users table to all other tables on the companyID I'm wondering if it's possible to create a custom funciton which could use the UserID to lookup the companyID and then pass this through as a parameter, and have this "GetCompanyID" function available when building Models and/or reports...???
When building a model the Information Functions available are GETUSERID and GETUSERCULTURE. Is it possible to modify how these work and/or create additional functions here???
Thanks in advance for your help.
Cheers,
Todd.
Hi,
I am creating a custom transformation component, and a custom user interface for that component.
In
my custom UI, I want to show the custom properties, and allow users to
edit these properties similar to how the advanced editor shows the
properties.
I know in my UI I need to create a "Property Grid".
In
the properties of this grid, I can select the object I want to display
data for, however, the only objects that appear are the objects that I
have already created within this UI, and not the actual component
object with the custom properties.
How do I go about getting the properties for my transformation component listed in this property grid?
I am writing in C#.
Hi,
I've created a Custom Data Flow Component and added some Custom Properties.
I want the user to set the contents using an expression. I did some research and come up with the folowing:
Code Snippet
IDTSCustomProperty90 SourceTableProperty = ComponentMetaData.CustomPropertyCollection.New();
SourceTableProperty.ExpressionType = DTSCustomPropertyExpressionType.CPET_NOTIFY;
SourceTableProperty.Name = "SourceTable";
But it doesn't work, if I enter @[System:ackageName] in the field. It comes out "@[System:ackageName]" instead of the actual package name.
I'm also unable to find how I can tell the designer to show the Expression editor. I would like to see the elipses (...) next to my field.
Any help would be greatly appreciated!
Thank you
Hi,
I'm trying to enable Expression for a custom property in my custom data flow component.
Here is the code I wrote to declare the custom property:
public override void ProvideComponentProperties()
{
ComponentMetaData.RuntimeConnectionCollection.RemoveAll();
RemoveAllInputsOutputsAndCustomProperties();
IDTSCustomProperty90 prop = ComponentMetaData.CustomPropertyCollection.New();
prop.Name = "MyProperty";
prop.Description = "My property description";
prop.Value = string.Empty;
prop.ExpressionType = DTSCustomPropertyExpressionType.CPET_NOTIFY;
...
}
In design mode, I can assign an expression to my custom property, but it get evaluated in design mode and not in runtime
Here is my expression (a file name based on a date contained in a user variable):
"DB" + (DT_WSTR, 4)YEAR( @[User::varCurrentDate] ) + RIGHT( "0" + (DT_WSTR, 2)MONTH( @[User::varCurrentDate] ), 2 ) + "\" + (DT_WSTR, 4)YEAR( @[User::varCurrentDate] ) + RIGHT( "0" + (DT_WSTR, 2)MONTH( @[User::varCurrentDate] ), 2 ) + ".VER"
@[User::varCurrentDate] is a DateTime variable and is assign to 0 at design time
So the expression is evaluated as: "DB189912189912.VER".
My package contains 2 data flow.
At runtime,
The first one is responsible to set a valid date in @[User::varCurrentDate] variable. (the date is 2007-01-15)
The second one contains my custom data flow component with my custom property that was set to an expression at design time
When my component get executed, my custom property value is still "DB189912189912.VER" and I expected "DB200701200701.VER"
Any idea ?
What I want to accomplish is that at design time the designer can enter a value for some custom property on my custom task and that this value is accessed at executing time.
View 10 Replies View RelatedI am writing a custom task that has some custom properties. I would like to parameterize these properties i.e. read from a varaible, so I can change these variables from a config file during runtime.
I read the documentation and it says if we set the ExpressionType to CPET_NOTIFY, it should work, but it does not seem to work. Not sure if I am missing anything. Can someone please help me?
This is what I did in the custom task
customProperty.ExpressionType = DTSCustomPropertyExpressionType.CPET_NOTIFY;
In the Editor of my custom task, under custom properties section, I expected a button with 3 dots, to click & pop-up so we can specify the expression or at least so it evaluates the variables if we give @[User::VaraibleName]

Just started SQL Class and I am struggling with an assignment.
Would someone be kind to give me some help please?
your task is to make a stored procedure that will only billcustomers making monthly payments higher than $500.A Customer can have multiple Plans (services for which they pay amonthly fee).
You have to execute a billing procedure for each single active planunder an eligible customer account. Eligible customer account is anaccount that makes estimated monthly payment higher than $500.
You are given 2 tables, "Customers" and "Plans". Table "Customers" has columns: CustomerID, EmailAddressTable "Plans" has columns: PlanID, CustomerID, MonthlyPrice, isClosed,NextBillDate
Also, you are given two stored procedures named "Bill_Plan" and"Send_Email". All stored procedures returns 0 upon success and negativenumber upon failure.The "Bill_Plan" actually bills a customer for a plan. The storedprocedure takes one input parameter and have one output parameter.
Bill_Plan
@nPlanID = @PlanID,
@dtNewBillDate = @NextBillDate output
You have to use the output parameter @NextBillDate to updatePlans.NextBillDate with its new value.
Upon successful billing you have to send en email to the customer'semail address. The "Send_Email" stored procedure takes two inputparameters.
Send_Email
@sEmailAddress = @EmailAddress,
@sSubject = 'Your Invoice is Ready'
You have to rollback any single billing transaction upon any kind offailure and continue billing the remaining plans. (Important!!!)
Thank signed I don't want to flunk!
