IMPORT vs REPLACE_ALL vs REPLACE_DATA

Asked by: 5073 views Data Mover

Once you have the data exported into the .DAT file from the source DB, you have many ways to push it into the target DB. IMPORT, REPLACE_ALL and REPLACE_DATA are available options that you can use. Can you compare between these commands?

    IMPROT : Irrespective of table existence in target, it imports data in target and if table is not present; it creates table, index and triggers. For transfer between two databases both must have identical records.

    REPLACE_ALL : Drops existing target table and creates new table and indices and imports.

    REPLACE_DATA : Drops existing target table data and creates replace with new data.
