Name

RECOVER

Description

This statement is used to restore a previously deleted database, table or partition

grammar:

1. restore database

   RECOVER DATABASE db_name;
   

2. restore table

   RECOVER TABLE [db_name.]table_name;
   

3. restore partition

   RECOVER PARTITION partition_name FROM [db_name.]table_name;
   

illustrate:

• If a new meta information with the same name and type is created after the meta information is deleted, the previously deleted meta information cannot be recovered

RECOVER DATABASE example_db;

2. Restore the table named example_tbl

RECOVER TABLE example_db.example_tbl;

3. Restore the partition named p1 in table example_tbl
