How Can I Efficiently Pass Multiple Rows to a Stored Procedure using ADO.NET?

Optimizing Data Transfer to Stored Procedures using ADO.NET

Leveraging table-valued parameters significantly improves database interaction efficiency in ADO.NET by enabling the transmission of multiple rows as a single parameter. This approach streamlines data handling and reduces the overhead associated with individual row insertions.

Parameterization Process:

1. Creating a User-Defined Table Type: Begin by defining a user-defined table type in SQL Server to mirror the structure of the data you intend to pass. This type serves as the blueprint for your parameter.
2. Developing the Stored Procedure: Next, create a stored procedure that accepts a table-valued parameter of the user-defined type created in the previous step.
3. Building the DataTable in C#: Within your C# code, construct a DataTable object. Ensure its columns precisely match the structure of your SQL Server user-defined type. Populate this DataTable with the rows of data you wish to send to the stored procedure.
4. Creating the SQL Parameter Object: Finally, create a SqlParameter object. Set its DataTypeName property to the name of your user-defined SQL Server type. Assign your populated DataTable to the Value property of this parameter.

This method allows developers to efficiently manage and transfer complex datasets to stored procedures, enhancing the performance of database operations within ASP.NET applications.
