Question

Here’s how my DataTable looks like(2 columns: Name and Code):

Name Code

name1 code1
name2 code2
name3 code3

I want to insert that DataTable into an existing table named MyTable that has a primary key and those 2 columns.

I really don’t know how I should start coding my Stored Procedure, Is there any way to send as parameter a DataTable or something like that?

Thank you.

In SQL-Server 2008 you can use table valued parameters. Something like this:

CREATE TYPE dbo.MyTableType AS TABLE 
(   Name    VARCHAR(5),
    Code    VARCHAR(5)
);
GO;
CREATE PROCEDURE dbo.MyProcedure (@MyTableType dbo.MyTableType READONLY)
AS
    INSERT dbo.MyTable (Name, Code)
    SELECT Name, Code
    FROM    @MyTableType;

GO;

Then simply pass your datatable as the value for a parameter (SqlDbType.Structured) in a SqlCommand.

Or you can use SQLBulkInsert and bypass the stored procedure.
