    Purpose

    You can use this statement to purge the tables, indexes, or all objects from the recycle bin.

    Syntax

    PURGE  { {TABLE object_name | INDEX object_name }
    | RECYCLEBIN
    };
    

    Parameters

    Parameter Description
    object_name The name of a table or an index to be purged from the recycle bin. Use the name that represents the table or index in the recycle bin, instead of its original name.
    Note
    • If you directly drop an index, the index will not be moved to the recycle bin.
    • If you directly drop a table with indexes, the table and its indexes are all moved to the recycle bin. When you purge a table from the recycle bin, the indexes of the table are also purged.
    RECYCLEBIN Purges the recycle bin.
    Notice: PURGE RECYCLEBIN will purge all objects from the recycle bin. Proceed with caution.

    Examples

    Sample tables and their data are defined as follows:

    obclient> CREATE TABLE tbl1(col1 INT,col2 INT);
    Query OK, 0 rows affected
    
    obclient> CREATE TABLE tbl2(col1 INT,col2 INT);
    Query OK, 0 rows affected
    
    obclient> CREATE INDEX tbl1_idx1 ON tbl1(col1);
    Query OK, 0 rows affected
    
    obclient> CREATE INDEX tbl2_idx2 ON tbl2(col1);
    Query OK, 0 rows affected
    
    obclient> DROP TABLE tbl1;
    Query OK, 0 rows affected
    
    obclient> DROP TABLE tbl2;
    Query OK, 0 rows affected
    
    obclient> SHOW RECYCLEBIN;
