1.模拟带有identity表

[db2inst1@xifenfei ~]$ db2 "create table t_xff(xid smallint not null generated always as identity
> (start with 1,increment by 1),x_name varchar(200)) in ts_xifenfei"
DB20000I  The SQL command completed successfully.
[db2inst1@xifenfei ~]$ db2 "insert into t_xff(x_name) values('www.xifenfei.com')"
DB20000I  The SQL command completed successfully.
[db2inst1@xifenfei ~]$ db2 "insert into t_xff(x_name) values('XIFENFEI')"
DB20000I  The SQL command completed successfully.
[db2inst1@xifenfei ~]$ db2 "insert into t_xff(x_name) values('xifenfei')"
DB20000I  The SQL command completed successfully.
[db2inst1@xifenfei ~]$ db2 "select * from t_ff"
SQL0204N  "DB2INST1.T_FF" is an undefined name.  SQLSTATE=42704
[db2inst1@xifenfei ~]$ db2 "select * from t_xff"
XID    X_NAME
------ -------------
     1 www.xifenfei.com
     2 XIFENFEI
     3 xifenfei
  3 record(s) selected.

2.导出表结构

[db2inst1@xifenfei ~]$ mkdir move_s
[db2inst1@xifenfei ~]$ cd move_s/
[db2inst1@xifenfei move_s]$ db2look -d sample -e -l -o db2_sample.ddl
-- No userid was specified, db2look tries to use Environment variable USER
-- USER is: DB2INST1
-- Creating DDL for table(s)
-- Output is sent to file: db2_sample.ddl

3.导出数据

[db2inst1@xifenfei move_s]$ db2move sample export
Application code page not determined, using ANSI codepage 1208

4.目标端创建数据库

C:\Windows\system32>db2 "create db db_XFF pagesize 8 k"
DB20000I  CREATE DATABASE命令成功完成。

5.目标端创建对象

C:\Windows\system32>DB2 -tvf D:\move_s\db2_sample.ddl -l d:\xifenfei.log
--检查xifenfei.log文件,发现错误,手工修复

6.导入数据文件

D:\move_s>db2move db_xff load

7.重新导入identity表

D:\move_s>db2 connect to db_xff
   数据库连接信息
 数据库服务器         = DB2/NT 9.5.0
 SQL 授权标识         = XIFENFEI
 本地数据库别名       = DB_XFF
D:\move_s>DB2 "load from tab19.ixf of ixf modified by identityoverride insert into db2inst1.t_xff"
SQL3501W  由于禁用数据库正向恢复，因此表所驻留的表空间将不被置于备份暂挂状态。
SQL3551W  表至少包含实用程序将覆盖的一个 GENERATED ALWAYS 列。
SQL3109N  实用程序正在开始从文件 "D:\move_s\tab19.ixf" 装入数据。
SQL3500W  在时间 "2012-04-15 23:06:52.393775"，实用程序在开始 "LOAD"。
SQL3150N  PC/IXF 文件中的 H 记录具有产品 "DB2    02.00"，日期 "20120405"和时间 "202132"。
SQL3153N  PC/IXF 文件中的 T 记录具有名称 "tab19.ixf"，限定符 "" 和源 ""。
SQL3519W  开始装入一致点。输入记录数 = "0"。
SQL3520W  “装入一致点”成功。
SQL3110N  实用程序已完成处理。从输入文件读了 "3" 行。
SQL3519W  开始装入一致点。输入记录数 = "3"。
SQL3520W  “装入一致点”成功。
SQL3515W  在时间 "2012-04-15 23:06:52.451619"，实用程序已经完成了 "LOAD"。
读取行数         = 3
跳过行数         = 0
装入行数         = 3
拒绝行数         = 0
删除行数         = 0
落实行数         = 3
D:\move_s>db2 "select * from db2inst1.t_xff"
XID    X_NAME
