The second is exported as.Sql files, use a text editor to view, versatility is good, but not as efficient as the first, suitable for small amount of import and export data. Particular attention is the table cannot have large fields (blob, CLOB, long), if any, will prompt cannot derive (tips are as follows: table contains one or more LONG columns cannot export in sql format,user Pl/sql developer format instead).
