Question

I have the following tsql function:

ALTER FUNCTION [dbo].[fn_MyFunc] (
        @AccountId varchar(50)
)
returns bit
as 
begin 

    declare @IsEligible bit
        --some calculation
    return @IsEligible


end 

Using c#, is that the way to call this tsql function and get its returned value?

     Database database = DatabaseFactory.CreateDatabase("DB");
     using (DbCommand dbCommand = database.GetStoredProcCommand("fn_MyFunc"))
                    {
                        database.AddInParameter(dbCommand, "@AccountId", DbType.String, "1234");
 bool returnedVAlue = (bool)dbCommand.ExecuteScalar();
}

Answer 1

Because you are calling a function you would have to call it using inline sql rather than a stored procedure. So rather than calling a stored proc you would call

select dbo.fn_myFunc(?) as result

You could also create a stored procedure that just wraps up the call to the function.
