Answer 1

Try using sp_executesql as the answer. Not the most efficient but it works

ALTER PROCEDURE [dbo].[uspTestReportData_GetBySerial] 
    @SerialNumbers nvarchar(200)
AS
BEGIN
    SET NOCOUNT ON;
    declare @sql nvarchar(200)

    set @sql = 'SELECT * from MyTable WHERE  Serial_Number in (' + @SerialNumbers + ')'
    execute sp_executesql @sql                    

END
