Question

I’m writing a converter for my database from MSSQL Express Edition to Oracle.
The amount of rows in the table is around 5 millions.
On MSSQL side I use LINQ to SQL to select data.
I’d use the same approach for Oracle, but unfortunately there’s no LINQ to Oracle in .NET.
I know there is open source LINQ to Oracle implementation, but I think I’ll use simple System.Data.OracleClient namespace.
My question is how to insert row to Oracle db at once? I’m afraid that if I’ll call ExecuteQuery() per row it would take a huge amount of time.
So is there any elegant solution for my problem?
Thanks.

The easiest way would be to forgo the program and use SQL Server Integration Services. You can link directly from MSSql server to the Oracle database and push the data over.
