I have an excel file with some columns as shown below.
I am using it as Excel Source in SSIS package.
I have Unpivotted the columns 2012, 2013 and 2014 using Unpivot Transform whose results look like
How can I send the output of this Unpivot Transform out of its data flow and Excecute SQL Task on it or send it to another Data Flow in the same package for various transformations? I do not want to use the option of writing the output of Unpivot Transform into OLEDB Destination and then Read them Back.
Thanks in Advance.
If you need to execute an SQL query on the Excel data, you can do this inside the DataFlow Task using an OLEDB Command transformation (The OLE DB Command transformation runs an SQL statement for each row in a data flow.)
Or you can use a RecordSet Destination to store data in a In-Memory Table (Table variable) and use it outside the DataFlow Task
You can follow the following links to learn more:

Problem is as simple Client want to store executable sql task queries result in Excel file.I have set full result set as a object but cant consume that object anywhere.
You need to export data from SQL Server to Excel using SSIS, right? In SSIS, you need to create a data flow task. Inside the data flow task you need an OLEDB data source or an ADO.NET data source. Then you need an Excel destination. Connect the source and destination and configure the mappings and other settings. More detailed instructions can be found in this tutorial: https://codingsight.com/export-data-from-sql-server-to-excel-and-text-file-via-using-ssis-package/
Add a Data Flow Task that contains a Script Component Source where you generate output rows from the recordset and an Excel Destination:

Implementing Recordset Source
On the other hand, you can simply use the SQL Command that you are executing in the Execute SQL Task in an OLE DB Source which is more simple.
Is there any way out there in SSIS, through which I can be able to get data first, and, then use that data inside my Script Task to generate a sqlite file.
You can use an OLE DB Connection and an OLE DB Source together to pull data out from SQL Server. Add an script task, configure it as a destination task,set the input columns an ad the code necessary to fill your sqlite tables.
I have a pretty heavy MDX query with many dimensions and measurements. I need to export the results of that MDX query to a SQL Server table using SSIS data flow (OLE DB Source --> SQL Command). I created an OLE DB Source, added "Format=Tabular" to its properties, and connected it to the OLE DB Destination. For a simple MDX query it runs fine.
But even for a simple query every time I copy and paste it in the SQL Command window (OLE DB Source) and press "OK" or "Columns" it looks like SSIS runs the whole query and returns the metadata then.
Is it possible to get just metadata without completely executing the query? I need to pass the metadata to the destination. I will appreciate any help on extracting the data from a cube into SQL Server table. Thanks.
That's been our experience with SSIS. The way we've got round it is to use a dummy query from a variable, that is returns the metadata to SSIS during design time. Then at runtime the actual variable is modified using another task (such as a script task) to be the full query.
I want to transfer data from tableA to tableB using SSIS. These tables are in the same server and database I am using OLEDB source and OLEDB destination. However it does not write any rows and there are no errors being reported.
If I change OLEDB source to read from a different server with the same database name it works. How can I recreate the SSIS package? All help appreciated.
Try to Use ADO.NET source and destination instead of OLEDB.
It wouldn't be problem if the tables are on same server, and database.
Create an Execute SQL task, which truncate you destination table.
Create a dataflow task, and create an ADO.NET source and destination inside the task.
If you haven't created package before:
you can also create SSIS package with ImportExportTool like this:
SSIS Tutorial, and check the Save SSIS package checkbox.
After the tool created the package, you can open it in visual studio and modify it.
The package will contain OLEDB source and destinations. It should work.
The data transformation components are very useful for a couple of issue.
How can I make identical output from a transformation go to two separate places e.g., an OLE DB destination and a DataReader destination?
Background:
I have an existing package that reads data from a text file, does some transformations, and loads the data into a SQL Server table.
Now I'm trying to make the package be callable from a reporting services report (SSRS). I'm following the instructions here: http://msdn.microsoft.com/en-us/library/ms159215.aspx
It says to make my data go into a DataReader destination and then the report will have access to that. So I want the output of the final transformation to go to both the SQL table, and the DataReader destination.
Use the MULTICAST and send to a "DataReader destination" and "OLEDB destination" in your SSIS package.
When you create your datasets in SSRS, you should use the name of the Output object from your SSIS package. Your dataset in the report should then populate with fields, data, etc that from the SSIS package.
Perhaps the Multicast step?
