1.資料庫表增加、修改字段
alter table itsm_cti add ci_table varchar(30)
修改資料庫字段
alter table smp_runtime_db2 alter last_backup set data type varchar(20);
alter table itsm_incident drop column deparment_id
連線至資料庫：
connect to user using password
2.db2資料庫中的資料操作（匯入匯出）
export to [path(例:d:"table1.ixf)] of ixf select [字段(例: * or col1,col2,col3)] from table1;
export to [path(例:d:"table1.del)] of del select [字段(例: * or col1,col2,col3)] from table1;
匯入表的資料
import from [path(例:d:"table1.ixf)] of ixf insert into table1
load from [path(例:d:"table1.ixf)] of ixf insert into table1;
3.匯出資料庫中所有表
d
b2look -d itsmv6 -e -i -db2inst1 -w db2inst1 -o itsm.ddl
4.查詢資料庫中表名匹配syscat.tables
select * from syscat.tables where tabname like '%base%';
5.重組表
su - db2inst1
之前需db2 connect to ynv6td user db2inst1 using db2inst1
db2 reorg table itsm_ci_computer
6.alter table itsm_portal_widget_user drop primary key;
7.select * from itsm_incident fetch first 10 rows only；
