How Can Array Binding with ODP.NET Optimize Bulk Inserts into Oracle from .NET?

Bulk Insert Optimization for Oracle with .NET

For bulk insertions into an Oracle database using .NET, the conventional method of executing an insert statement for each record can be time-consuming, especially with large datasets. Here's a superior approach:

Utilizing Array Binding with ODP.NET (Oracle Data Provider for .NET) has proven to be highly efficient. This technique involves creating a stored procedure and passing arrays of parameter values to the procedure. Oracle then executes the stored procedure multiple times using the bulk values provided from .NET in a single operation.

By adopting this approach, you can significantly reduce the execution time. For instance, inserting 50,000 records using Array Binding can be completed in approximately 15 seconds.

To implement Array Binding:

1. Create a stored procedure that performs the insert operations.
2. In your .NET code, use the OracleCommand object to create an array binding.
3. Associate the parameter arrays with the corresponding stored procedure parameters.
4. Execute the OracleCommand, which will invoke the stored procedure and insert the bulk data efficiently.

This approach offers a substantial performance improvement over the conventional method of individual insert statements.
