OraDump to MySQL converter merges data according to the following algorithm. If a table does not have primary key or an unique index, the tool appends all rows from Oracle table to the corresponding MySQL table. Otherwise, the converter inserts into MySQL table only those records whose key/index value does not exist in the destination table. If the structures of source and destination tables are different, OraDump to MySQL converter transforms each record of Oracle table so that it conforms to the target table structure.
