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:
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.
[One day I will come back here and answer questions, rather than only ask.]
I have a custom connection manager that returns an OleDbConnection. The only thing "custom" about the connection manager is how it determines its connection string. The object returned in AcquireConnection is an OleDbConnection.
OleDbConnection oleDbConnection = new OleDbConnection(this.connectionString); oleDbConnection.Open();
return oleDbConnection; }
Some of the objects within SSIS only work with an OleDbConnection, but mine is not recognized as such. Is there any way to have my connection recognized as a valid connection?
I am running into issues with custom objects interaction with visual studio 2005.
1. Custom connection manager. I am setting the name of the connection manager ( to standardize naming convention ) that user created, however when the CM is created, the name displayed in visual studio is still the default name even if the real name is the one i set. I have to do things like, edit it or save package - close - reopen, create another connection, ... etc in order to get it refreshed.
2. Custom Task I am managing some variables in this custom task so that I will be adding and deleting variables in the package. The challenge i am running into is, when I added 2 variables for example, even though the variables are successfully added to package, the Variable Window in visual studio designer will not reflect the new variables. I have to save package, close, and re-open in order for the variables to show up.
So this brings to my question - is there any way to tell Visual Studio programmatically to refresh the contents of these 2 sections, 1 is the Variable Window and the other is the panel containing the list of connection managers.
I have been searching around and found some clue about visual studio SDK but I still cannot find an exact way of doing it. Visual Studio SDK example tells you how you can access the Variable window as
SP2 for SQL Server 2005 x64 has been less than happy for me.
The initial problem, mentioned in another thread, concerned SSIS client which stopped liking Data Flow components. It was solved by a removal and reinstallation of the client tools.
However, there now seems to be a problem with making use of the Teradata oledb provider within SSIS. Prior to the installation of SP2 there was no problem.
I create a new SSIS package Add a Data Flow component Within the data flow add an oledb source Create a new connection - using the Teradata oledb provider Test the connection (it works!) Use SQL something like "select * from some_teradata_table_on_the_TD_server" Click on columns, wait a second, a list of columns is returned Add a SQL Server destination (with a new SQL Server connection) Connect the two components Save the package
Click go The TD oledb source component turns bright red and the error is "class not registered"
I have uninstalled the TD oledb provider (and underlying TD components) and re-installed (32-bit and 64-bit) - no change
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?
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.
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

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.
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 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?
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]
I have a package that uses a for loop to iterate through an unknown amount of excel files and pull their data into a table. However, there will be cases when the file is corrupted or has some sort of problem so that either the transformation will fail or the excel data source will fail with an oledb connection error. Could anyone suggest a clean way to trap these errors? Specifically, the "Cannot Aquire Connection from Connection Manager", which is the excel connection.
for some reasons, I have to get access to the TaskHost during validation and execution. For example, I wanna know, if my task is within a container or not (parent is Sequence).
For the UI during design time, there is the TaskHost parameter. What about the execution time or during validation?
HI, I am going to make a big web application. so im going to use sql connection with class for example i have 100 web pages and i will make a slq connection in class.vb Class1.vb(see the below code) Imports System.Data Imports System.Data.SqlClient Imports Microsoft.VisualBasicPublic Class Class1 Private conn As New SqlConnection("Data Source=DANISHSQLEXPRESS;Initial Catalog=ARBASHHR.MDF;Integrated Security=True")Private cmd As New SqlCommand() Private da As New SqlDataAdapter(cmd) End Class default.aspx(here is asp.net page i want to use the sql connection from that class.) but this below page saying that Name "cmd" is not declared and connection Try cmd.Connection = conn conn.Open()Dim ds As New DataSet cmd.CommandText = "SELECT * FROM Users where (UserName = N'" & TextBox1.Text & "')" 'And (Password = N '" & TextBox2.Text & "')"da.Fill(ds, "data") conn.Close() For Each dt As DataTable In ds.Tables For Each dr As DataRow In dt.RowsTextBox3.Text = dr.Item("Password") Next drNext dt If TextBox2.Text = TextBox3.Text ThenResponse.Redirect("Welcome.aspx") Else Label3.Text = "Invalid Username/password" End IfCatch ex As Exception ' MsgBox(ex.Message) '("Error Loading Information From Database..", MsgBoxStyle.Critical, "Error") End Try End Sub please let me know where im doing mistake..... Thank in Advance
I added a connection (ADO.NET) object by name testCon in the connection manager - I wanted to programmatically supply the connection string. So I used the "Expressions" property of the connection object and set the connectionstring to one DTS variable. The idea is to supply the connection string value to the variable - so that the connection object uses my connection string.
Then I added a "Backup Database Task" to my package with the name BkpTask. Now whenever I try to set the connection property of BkpTask to the testCon connection object, by typing testCon, it automatically gets cleared. I am not able to set the connection value.
Then after spending several hours I found that this is because I have customized the connection string in testCon. If I don't customize the connection string, I am able to enter the "testCon" value in the connection property of the BkpTask.
Hi enquiring whether is it more efficient to use OLEDB destination to update and extract all records from table A to tabl e B or use script task? And whether OleDB destination perform row by row update? Finally will data integrity be affected if i run delete, update and insert operations in the same data flow but extracting different sets of data each time from the 2 tables?
I have a strange problem, which I never encountered earlier, I have a data flow which has one source and multiple destinations, I am also using multicast and derived column transformations too, however when I run the package (either from cmd line or designer) the data flow task hangs when it comes to inserting data into the target tables. and it keeps waiting forever. Initialy I thought it was my data set , however if with very few records the problem persists. I have also tried removing the table lock from the destination , increasing the rows per batch to 10000 and commit size to 10000 but to no change. I am using the fast load option within my destination. When I run sp_who2 on my Management Studio I see that the status of all the processes is sleeping and the command is "awaiting command" , any help appreciated.
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..............
Inside a data flow task, i have a oledb source and destination. In my situation, I need to pull data from a table in the source, but also hard code some columns myself, which means my source is a blend of data from table, hard coded data, which will then have to be mapped to columns in oledb destination. Does anyone which option to choose in the oledb source dropdown for the data access mode. Keep in mind, i do need to run a a select query, as well as get data from a table. Is it possible to use multiple oledb sources and connect to one destination, because that is really what intend to do here. I am not sure how it will work, or even if its possible. Basically my source access mode needs to be a blend of sql command and table columns, how would that be implemented? Any help or advice is appreciated.
Hi, I'd like to know which is the best choice to execute a store procedure that execute transformations from table to files using bcp command, 2 millions rows everyday (i'ts a Data Warehouse database). So in the sql task in connectionType I had choiced ADO.NET is the best option? Thanks
I am having a problem on updating data in DB2 target table.
I followed BJ Custard's (http://forums.microsoft.com/MSDN/ShowPost.aspx?PostID=1058272&SiteID=1&mode=1)(thanks amillion!) post and configured OLEDB destination to insert data. But I have to also update or delete data from the target table based on flag from source.
I tried using OLEDB command which uses the OLEDB connection created by following the steps posted in above link.
Trail 1real requirement): When I used the SQL query:
delete from table where Col1=? and Col2=?
I am unable to map to the parameters. When I click refresh button after writing the query, I get "There is a data source column with no name. Each data source column must have a name." message. Added to before message, there are no parameters to map to.
Trail 2: When I hard code the parameters :
delete from table1 where Col1='abc' and Col2='xyz'
no parameters will come up, so no mapping. So when I execute the mapping I get the following error:
Error: 0xC0202009 at Load .....................................................: SSIS Error Code DTS_E_OLEDBERROR. An OLE DB error has occurred. Error code: 0x80040E00. Lookup on above error codes show those are related more to target Db2 database.
I am sure some one might have used the OLEDB command task, not only just insert task.
My package needs to be a High Performance (target: 150,000 rows in 30 minutes) ETL solution. We are using all MS technologies - SSIS, SQL 2005, BIDS, etc. I need to loop the recordset executed by a Stored Proc in a Execute SQL Task in a Source Script Component.
If I use an ADO.NET Connection Manager, here is the code in the Source Script Component Public Overrides Sub CreateNewOutputRows()
Code 1
Dim sqlAdapter As New SqlDataAdapter
Dim dataRow As Data.DataRow
Dim ds As DataSet = CType(Me.Variables.rsSomeResultset, DataSet)
sqlAdapter.Fill(ds)
Iget: Error: System.InvalidCastException: Unable to cast object of type 'System.Object' to type 'System.Data.DataSet'.
Code 2
Dim oledbAdapter As New OleDb.OleDbDataAdapter Dim dataTable As DataTable
Error: System.ArgumentException: Object is not an ADODB.RecordSet or an ADODB.Record. Parameter name: adodb
It works all right when I use an OLEDB Connection Manager with the second code sample.
Question: In order to extract the maximum performance, wouldn't it be preferred to use ADO.NET with SqlClient Provider in an all SQL Server 2005 environment? Or will an OLEDB Connection provide comparable or equal performance?
If so, what code can I use? Since the recordset returned by the Stored Proc (in the Execute SQL Task) can only be captured in a System.Object variable and you can only use the overload of the Fill() method of the OleDbDataAdapter to accept an ADO Recordset or Record object.
Are there compelling reasons to use one versus the other? I am completely redeveloping all of our site from .ASP, VBScript and Access, to ASP.NET, VB.NET and SQL Server 2005 Express. I have a lot of code in ADO and OLEDB already, and would like to make the change to the System.Data.SQLClient classes if I should.
I have tried to connect ce database by using c++ and oledb, and failed in every turn, i dont know what i did wrong...
I created a new database by using create a new database sample in ssce bol, but i couldnt connect that database, it says invalid class string or authentication failed...
I know this has been a topic of discussion before and I have read and tried the suggestions to no avail. I have a few .dbf files to import into my sql database and I know that one needs to make a oledb connection to these files.
I am using the Jet provider and have tried setting the extended properties to all of the DBASE versions and still cannot get it to connect. These files' names are shorter than 8 chars so that issue is no problem in this case. I can actually get these files to show in a Microsoft Access 2008 database when I import it from there so I know that I must be missing something in my SSIS project.
After doing some reading on this topic, it would seem that this shouldn't be such a schlepp but, here I am
