Copy from a query into a table.
The COPY command works for remote and even non-oracle databases.
Syntax:
COPY {
FROM username[/password]@db_spec |
TO username[/password]@db_spec |
FROM username[/password]@db_spec TO username[/password]@db_spec
}
{APPEND|CREATE|INSERT|REPLACE}
destination_table
[(column, column, column ...)]
USING query
options:
FROM Source database (defaults to current)
TO Destination database (defaults to current)
USING The SELECT statement(source of data to copy)
APPEND Insert into the destination_table
COPY will create the destination_table if does not exist.
CREATE Insert into the destination_table
CREATE will fail with an error if the destination_table already exists.
INSERT Insert into the destination_table
INSERT will fail with an error if the destination_table does not already exist.
Columns in the USING query must match those in the destination_table.
REPLACE Replace destination_table and its contents with rows from query.
REPLACE will drop the destination_table(if it exists)and
replace it with a table containing the copied data.
Columns created with NUMBER datatype will default to NUMBER(38)
it is often more efficient to CREATE TABLE AS and then COPY... INSERT
