Read and Write to Text file – VB.Net

I created this snippet to save my search time in future. So, you can also make use of this if needed.

The main objective of this code is to read a text file line by line and write it into another file. I know, it looks silly. because, why do we need to read a file and write to others without doing anything. But, The actual purpose is to read a text file and do some operations like update or remove. Using this method I can keep my original file unchanged. does it make sense now?

Code snippet

Imports System.IO

Dim strLine As String
Dim objStreamReader As StreamReader
Dim objStreamWriter As StreamWriter

objStreamReader = New StreamReader(“C:\test\source.txt”)
objStreamWriter = New StreamWriter(“C:\test\destination.txt”)

strLine = objStreamReader.ReadLine

Do While Not strLine Is Nothing
strLine = objStreamReader.ReadLine

‘Close the file.

I know there are millions of ways to do something. But, I choose this method and if you have a new logic please share it in the comment section.

SQL SERVER – Declare Mulitple Variables in Single Line

This may be a simple thing, but sometime new developers are difficult to find this information readily. So, thought of adding it in this website.

How to declare and initialize variables in single or multiple lines?


Declaring variables – Multiple lines


Declare and Initialize variables – Multiple lines

DECLARE @int_i AS INT = 1;
DECLARE @chr_Name AS VARCHAR(50) = ‘Test';

Declare variables in single line

DECLARE @int_i AS INT, @chr_Name AS VARCHAR(50);

Declare and Initialize variables in single line

DECLARE @int_i AS INT = 1, @chr_Name AS VARCHAR(50) = ‘Test';

That is it, You have learned to declare and initialize variables in MS SQL Server.

Unpivot Transformation with Example- SSIS

This blog post is just to give a step by step instruction to work with Unpivot Transformation in SSIS.


Unpivot Transformation is used to convert unnormalized dataset into normalized dataset. Database Normalization.


For instance, we have got a data as show in the below image and we want to normalize the data to make the user table compact.


In this dataset, Column 1 contains Customer names, column 2 to 6 contains product names and each data cell represents the quantity purchased by the customer. But to store this data in the RDBMS, we need to convert this dataset into normalized structure. So, In normalizes structure this data will looks like this.


Now, we are going to implement this scenario in using SSIS.

Table Creation:

CREATE TABLE [dbo].[tblPurchase](
[Customer] [nchar](10) NULL,
[Ham] [nchar](10) NULL,
[Soda] [nchar](10) NULL,
[Milk] [nchar](10) NULL,
[Beer] [nchar](10) NULL,
[Chips] [nchar](10) NULL

Insert rows:

INSERT INTO [dbo].[tblPurchase]
(‘Kate’,’2′, ‘6’, ‘1’, ’12’,NULL),
(‘Robert’,NULL, ‘1’,’2′,’3′,’1′),

Step 1: Create a new package

Step 2: Add a Data Flow Task in to package and Go to Data Flow environment

Step 3: Add a OLE DB source task to configure to read the table.


Step 4: Add Unpivot transformation. This task is used to convert unnormalized dataset to normalized dataset. Unpivot Transformation Editor.


Notice that the customer column is removed from the pivot input column and setup the output column as quantity and the product column as pivot key. So, we will get the output of Product and its quantity for each customer in multiple rows.

Note: All null value quantity rows will be removed by this transformation.

Step 5: Use the OLE destination column to store the unpivoted output in the normalized table. In this example, I am using the union all transformation as the destination and added data viewer to browse the output in the pipeline.


Step 6: Execute the package


This output show that the unpivoted dataset is in normalized structure.

Now, You can easily normalize any unnomalized dataset using Unpivot Transformation task in SSIS. I hope you have enjoyed reading this article. So, please share your thoughts and question in the comment section.

Execute Stored Procedure with Input and Output Parameters and Return Status in SSIS

In this blog post, I would like to show a simple example on how to handle or use the stored procedure that has  input , output parameter and return status value in SSIS.

Create Stored Procedure in SQL Server

CREATE PROCEDURE usp_TestProcedure
    @MyInput varchar(100),
    @MyOutput varchar(100) OUTPUT
    SET @MyOutput = ‘SQL Server Rider';
    RETURN 5;

This user procedure has two parameters input and output. I also returns a return status. All these parameters and return values are imaginary and has no purpose.

Execute usp_TestProcedure in Query window

EXEC [dbo].[usp_TestProcedure] ‘Blogger’, @Output OUTPUT
PRINT @Output

@Output is the character variable and also act as an output parameter variable to bring back the value of the @MyOutput parameter in the stored procedure.

To execute the same stored procedure in the SSIS, we are going to use Execute SQL Task. So, We need to create three variables in the package to execute this stored procedure.

Step 0: Create SSIS solution in SS

Step 1: Add 3 package variables with correct data type.


Step 2: Add and Configure the SQL Execute Tast


Configure Database connection, Stored procedure and its parameters.


SQL Statement: exec ? = usp_TestProcedure ?,? OUTPUT

Map variables to Input/output parameters and return value .


Step 3: Executing the package and watch the variable’s value during run-time.


Package execution succeeded by calling the stored procedure.

Common mistake

We need to Map the parameters in sequential order. It means, in this example parameter 0 is return value and 1 is the input and 2 is the output parameter.
