Question

I am in the process of migrating some legacy code to LINQ to SQL and I am having some difficulty with the following Stored Procedure.

BEGIN
    INSERT INTO tblCMOEncounterHeader (
        submitter_organization_id, 
        submission_date, 
        begin_posting_date,
        end_posting_date, 
        number_of_records_transmitted) 
    VALUES (
        @submitter_organization_id,
        @submission_date,
        @begin_posting_date,
        @end_posting_date,
        @number_of_records_transmitted)

    RETURN @@ROWCOUNT
END

Specifically, what does @@ROWCOUNT return when partnered with an INSERT? How would I accomplish the same thing in LINQ?

Answer 1

@@ROWCOUNT 

Returns the number of rows affected by the last statement

MSDN

In your case it will always return 1, I guess, or raise an error in case of constraint violation, etc.

Your LINQ to SQL code should definitely return (numsRowsAffected > 0);, i.e. a boolean value or something similar
