一、加载数据:
1、 以默认分隔符加载,默认为“,”号
db2 "import from btpoper.txt of del insert into btpoper"
2、 以指定分隔符“|”加载
db2 "import from btpoper.txt of del modified by coldel| insert into btpoper"
二、卸载数据:
1、 卸载一个表中全部数据
db2 "export to btpoper.txt of del select * from btpoper"
db2 "export to btpoper.txt of del modified by coldel| select * from btpoper"
2、 带条件卸载一个表中数据
db2 "export to btpoper.txt of del select * from btpoper where brhid='907020000'"
db2 "export to cmmcode.txt of del select * from cmmcode where codtp='01'"
db2 "export to cmmcode.txt of del modified by coldel| select * from cmmcode where codtp='01'"
三、查询数据结构及数据:
db2 "select * from btpoper"
db2 "select * from btpoper where brhid='907020000' and oprid='0001'"
db2 "select oprid,oprnm,brhid,passwd from btpoper"
四、删除表中数据:
db2 "delete from btpoper"
db2 "delete from btpoper where brhid='907020000' or brhid='907010000'"
五、修改表中数据:
db2 "update svmmst set prtlines=0 where brhid='907010000' and jobtp='02'"
db2 "update svmmst set prtlines=0 where jobtp='02' or jobtp='03'"
六、联接数据库
db2 connect to btpdbs
七、清除数据库联接
db2 connect reset 断开数据库连接
db2 force applications all 断开所有数据库连接
十二、查看数据库参数:
db2 get dbm cfg
db2 get db cfg for btpdbs
十三、修改数据库参数:
db2 update db cfg for btpdbs using LOGBUFSZ 20
db2 update db cfg for btpdbs using LOGFILSIZ 5120
改完后,应执行以下命令使其生效:
db2 stop
db2 start
补充:
db2 set schema btp 修改当前模式为"btp"
db2 list tablespaces show detail 查看当前数据库表空间分配状况
db2 list tablespace containers for 2 show detail 查看tablespace id=2使用容器所在目录
db2 list application
db2 list db directory 列出所有数据库
db2 list active databases 列出所有活动的数据库
db2 list tables for all 列出当前数据库下所有的表
db2 list tables for schema btp 列出当前数据库中schema为btp的表
db2 list tablespaces show detail 显示数据库空间使用情况
db2 list packages for all
db2 list applications
db2 "force applications (353)"
db2 "import from tab76.ixf of ixf commitcount 5000 insert into achact"
db2 "create table achact_t like achact"
db2 "rename table achact_t to achact"
db2 "insert into achact_t select * from achact where txndt>=(select lstpgdt from
acmact where actno=achact.actno)"
