I have a connection string to read from a SQL data base and another to read from an Excel spreadsheet. However how do I handle a situation where I want to read records from an excel spreadsheet and insert them into my SQL database

example
Insert into DCR_transaction_master  SELECT * from [DCR_transaction_master$] where T2_transactionId='&TransactionId'

What connection string do I provide with this type of statement which is reading from Excel and writing to SQL DB?

regards
Pat

This article seems to provide a really good way to do what you want, and it also shows the use of multiple connection strings, as you are asking about that:
http://code.msdn.microsoft.com/office/Imoprt-Data-from-Excel-to-705ecfcd

However, if that's not enough, I would do it this way. It might not be the fastest or most efficient, but it would work:

1. Write a method to insert the data into the SQL database using the connection string using SQLConnection and SQLCommand. Use the "using" statement:

Using (SqlConnection conn = new SqlConnection("SQL DB Connection String))
{
   // do the insert using a SqlCommand
}

Have this method take in the appropriate data structure (a Class or Struct as you would define it).

Then, in a separate method, read each row from the Excel sheet and populate the structure or class. Pass in that populated structure/class to the method that inserts it into SQL.
