Is there a way to check, before an insert if that particular order already exists in the table?

Yes; the primary key. That's the one that uniquely identifies a tupel/record. Hence, that's what you'd need to check. Most databases will do this automatic and throw an error if the record already exists.

if the process fails in the middle, and i want to start it again, if there are already some rows in the table, not to insert those.

Select a list of all primary key-values in the table, and skip those inserts.
