8.enabling automatic extension of data files
sql>alter tablespace app_data add datafile 'c:\oracle\oradata\app_data01.dbf' size 200m
sql>autoextend on next 10m maxsize 500m;
9.change the size to data files manually
sql>alter database datafile 'c:\oracle\oradata\app_data.dbf' resize 200m;
10.Moving data files:alter tablespace
sql>alter tablespace app_data rename datafile 'c:\oracle\oradata\app_data.dbf' to 'c:\oracle\app_data.dbf';
11.moving data files:alter database
sql>alter database rename file 'c:\oracle\oradata\app_data.dbf' to 'c:\oracle\app_data.dbf';
第三章：表
1.create a table
sql>create table table_name(column datatype, column datatype,...)
sql>tablespace tablespace_name [pctfree integer] [pctused integer]
sql>[initrans integer] [maxtrans integer]
sql>storage(initial 200k next 200k pctincrease 0 maxextents 50)
sql>[logging|nologging] [cache|nocache]
2.copy an existing table
sql>create table table_name [logging|nologging] as subquery
3.create temporary table
sql>create global temporary table xay_temp as select * from xay;
on commit preserve rows/on commit delete rows
4.pctfree=(average row size - initial row size)*100/average row size
pctused=100-pctfree-(average row size*100/available data space)
5.change storage and block utilization parameter
sql>alter table table_name pctfree=30 pctused=50 storage(next 500k minextents 2 maxextents 100);
6.manually allocating extents
sql>alter table table_name allocate extent(size 500k datafile 'c:\oracle\data.dbf');
7.move tablespace
sql>alter table employee move tablespace users;
8.deallocate of unused space
sql>alter table table_name deallocate unused [keep integer]

sql>alter table table_name drop columns continue;
12.mark a column as unused
sql>alter table table_name set unused column comments cascade constraints;
sql>alter table table_name drop unused columns checkpoint 1000;
sql>atler table orders drop columns continue checkpoint 1000 data_dictionary:dba_unused_col_tabs
第四章：索引
1.creating function-based indexes
sql>create index summit.item_quantity on summit.item(quantity-quantity_shipped);
2.create a B-tree index
sql>create [unique] index index_name on table_name(column,..asc/desc) tablespace
sql>tablespace_name [pctfree integer] [initrans integer] [maxtrans integer] [logging|nologging] [nosort] storage(initial 200k pctincrease 0 maxextents 50);
3.pctfree(index)=(maximum number of rows-initial number of rows)*100/maximum number of rows
4.creating reverse key indexes
sql>create unique index xay_id on xay(a) reverse pctfree 30 storage(initial 200k next 200k pctincrease 0 maxextents 50) tablespace indx;
