The Below Code will be useful in the cases when we need to deal with flat files, wherein the file structure may be dynamic and we are dealing with multiple files each one with a different schema definition. The approach will be here is to loop through each file and then read the first line of each file and read the column names from the file and then dynamically create the table and then load the data. The below code is used to read the column information from the file and then generate a SQL Command which will create the table in the database. Here it goes -  Code to dynamically create a table using the Input File Data – Public Sub Main()         Dim objReader As New StreamReader(Dts.Variables( "SRCDATAFILE" ).Value.ToString)         Dim sLine As String = ""         Dim arrText As New ArrayList()       ...

Duplicate data is a very well known and frequently occurring issue in any DBMS and dealing with deletion of duplicate data is something not that easy for one specially one who is dealing with crucial and huge data. There are 2 scenarios which can come while deleting duplicate data - 1. when we have an identity column in our table containing duplicates. The problem becomes much easier here and we can just keep the data with MIN or MAX keys removing all other. --Create New Table create table Person ( ID int identity ( 1 , 1 ), Name varchar ( 30 ), age int ) --Insert Data into Table with multiple Duplicate entries insert into Person ( Name , age ) values ( 'Ashish' , 24 ) insert into Person ( Name , age ) values ( 'Ashish' , 24 ) insert into Person ( Name , age ) values ( 'Gaurav' , 26 ) insert into Person ( Name , age ) values ( 'Nayan' , 25 ) insert into Person ( Name , age ) values ( 'Nayan...
