下面一条龙实现linux平台下 DB2数据库的简单操作：
从实例用户(db2inst1) 查实例下的数据库、创建/删除实例下的数据库 查询数据库SAMPLE包含的所有表 查询表数据。
1.切换到实例用户：db2inst1
infosrvr:~/Desktop # su - db2inst1 db2inst1@infosrvr:~>
2.列出实例下的所有数据库
infosrvr:~/Desktop # su - db2inst1 db2inst1@infosrvr:~> db2inst1@infosrvr:~> db2 list db directory System Database Directory Number of entries in the directory = 4 Database 1 entry: Database alias = XMETA Database name = XMETA Local database directory = /opt/IBM/InformationServer/Repos/xmeta Database release level = d.00 Comment = Directory entry type = Indirect Catalog database partition number = 0 Alternate server hostname = Alternate server port number = Database 2 entry: Database alias = QS Database name = QS Local database directory = /home/db2inst1 Database release level = d.00 Comment = Directory entry type = Indirect Catalog database partition number = 0 Alternate server hostname = Alternate server port number = Database 3 entry: Database alias = TEST1 Database name = TEST1 Local database directory = /home/db2inst1 Database release level = d.00 Comment = Directory entry type = Indirect Catalog database partition number = 0 Alternate server hostname = Alternate server port number = Database 4 entry: Database alias = SAMPLE Database name = SAMPLE Local database directory = /home/db2inst1 Database release level = d.00 Comment = Directory entry type = Indirect Catalog database partition number = 0 Alternate server hostname = Alternate server port number =
3.创建新的数据库
db2inst1@infosrvr:~> db2 create db test2 DB20000I The CREATE DATABASE command completed successfully.
4.删除数据库
db2inst1@infosrvr:~> db2 drop db test2 DB20000I The DROP DATABASE command completed successfully.
5.连接到数据库
db2inst1@infosrvr:~> db2 connect to sample Database Connection Information Database server = DB2/LINUX 9.7.4 SQL authorization ID = DB2INST1 Local database alias = SAMPLE
6.查看数据库中的表
db2inst1@infosrvr:~> db2 list tables Table/View Schema Type Creation time ------------------------------- --------------- ----- -------------------------- ACT DB2INST1 T 2012-01-17-09.38.24.314033 ADEFUSR DB2INST1 S 2012-01-17-09.38.30.953823 CATALOG DB2INST1 T 2012-01-17-09.38.45.758734 CL_SCHED DB2INST1 T 2012-01-17-09.38.17.264534 CUSTOMER DB2INST1 T 2012-01-17-09.38.42.650735 DEPARTMENT DB2INST1 T 2012-01-17-09.38.17.922386 DEPT DB2INST1 A 2012-01-17-09.38.19.113115 EMP DB2INST1 A 2012-01-17-09.38.20.001560 EMPACT DB2INST1 A 2012-01-17-09.38.24.312415 EMPLOYEE DB2INST1 T 2012-01-17-09.38.19.114152 EMPLOYEES DB2INST1 T 2012-01-31-12.29.59.242048 EMPLOYEESBCK DB2INST1 T 2012-01-31-12.30.01.379628 EMPMDC DB2INST1 T 2012-01-17-09.38.33.972494 EMPPROJACT DB2INST1 T 2012-01-17-09.38.24.072812 EMP_ACT DB2INST1 A 2012-01-17-09.38.24.313415 EMP_PHOTO DB2INST1 T 2012-01-17-09.38.20.002277 EMP_RESUME DB2INST1 T 2012-01-17-09.38.20.913174 INVENTORY DB2INST1 T 2012-01-17-09.38.41.945239 IN_TRAY DB2INST1 T 2012-01-17-09.38.25.117312 ORDERS DB2INST1 T 2012-01-31-12.30.00.875412 ORDERS_REPORT DB2INST1 T 2018-04-30-03.23.21.691567 ORG DB2INST1 T 2012-01-17-09.38.25.248487 PRODUCT DB2INST1 T 2012-01-17-09.38.40.533568 PRODUCTSUPPLIER DB2INST1 T 2012-01-17-09.38.52.256502 PROJ DB2INST1 A 2012-01-17-09.38.23.450158 PROJACT DB2INST1 T 2012-01-17-09.38.23.450891 PROJECT DB2INST1 T 2012-01-17-09.38.22.005809 PURCHASEORDER DB2INST1 T 2012-01-17-09.38.43.886457 SALES DB2INST1 T 2012-01-17-09.38.25.597600 STAFF DB2INST1 T 2012-01-17-09.38.25.364715 STAFFG DB2INST1 T 2012-01-17-09.38.28.800946 SUPPLIERS DB2INST1 T 2012-01-17-09.38.51.099347 VACT DB2INST1 V 2012-01-17-09.38.26.143195 VASTRDE1 DB2INST1 V 2012-01-17-09.38.26.217231 VASTRDE2 DB2INST1 V 2012-01-17-09.38.26.302266 VDEPMG1 DB2INST1 V 2012-01-17-09.38.26.205180 VDEPT DB2INST1 V 2012-01-17-09.38.25.733555 VEMP DB2INST1 V 2012-01-17-09.38.26.136359 VEMPDPT1 DB2INST1 V 2012-01-17-09.38.26.211423 VEMPLP DB2INST1 V 2012-01-17-09.38.26.520095 VEMPPROJACT DB2INST1 V 2012-01-17-09.38.26.192738 VFORPLA DB2INST1 V 2012-01-17-09.38.26.499173 VHDEPT DB2INST1 V 2012-01-17-09.38.26.132636 VPHONE DB2INST1 V 2012-01-17-09.38.26.515803 VPROJ DB2INST1 V 2012-01-17-09.38.26.139689 VPROJACT DB2INST1 V 2012-01-17-09.38.26.148497 VPROJRE1 DB2INST1 V 2012-01-17-09.38.26.306779 VPSTRDE1 DB2INST1 V 2012-01-17-09.38.26.312796 VPSTRDE2 DB2INST1 V 2012-01-17-09.38.26.494157 VSTAFAC1 DB2INST1 V 2012-01-17-09.38.26.505147 VSTAFAC2 DB2INST1 V 2012-01-17-09.38.26.509563 51 record(s) selected.
