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 ***** DB2MOVE ***** Action: EXPORT Start time: Thu Apr 5 20:21:28 2012 Connecting to database SAMPLE ... successful! Server : DB2 Common Server V9.5.9 Binding package automatically ... /home/db2inst1/sqllib/bnd/db2common.bnd ... successful! Binding package automatically ... /home/db2inst1/sqllib/bnd/db2move.bnd ... successful! EXPORT: 18 rows from table "DB2INST1"."ACT" EXPORT: 5 rows from table "DB2INST1"."CL_SCHED" EXPORT: 14 rows from table "DB2INST1"."DEPARTMENT" EXPORT: 42 rows from table "DB2INST1"."EMPLOYEE" EXPORT: 10000 rows from table "DB2INST1"."EMPMDC" EXPORT: 73 rows from table "DB2INST1"."EMPPROJACT" EXPORT: 8 rows from table "DB2INST1"."EMP_PHOTO" EXPORT: 8 rows from table "DB2INST1"."EMP_RESUME" EXPORT: 145 rows from table "SYSTOOLS"."HMON_ATM_INFO" EXPORT: 0 rows from table "SYSTOOLS"."HMON_COLLECTION" EXPORT: 3 rows from table "DB2INST1"."IN_TRAY" EXPORT: 8 rows from table "DB2INST1"."ORG" EXPORT: 5 rows from table "SYSTOOLS"."POLICY" EXPORT: 65 rows from table "DB2INST1"."PROJACT" EXPORT: 20 rows from table "DB2INST1"."PROJECT" EXPORT: 41 rows from table "DB2INST1"."SALES" EXPORT: 35 rows from table "DB2INST1"."STAFF" EXPORT: 35 rows from table "DB2INST1"."STAFFG" EXPORT: 3 rows from table "DB2INST1"."T_XFF" Disconnecting from database ... successful! End time: Thu Apr 5 20:21:32 2012
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 ***** DB2MOVE ***** Action: LOAD Start time: Sun Apr 15 23:00:17 2012 Connecting to database DB_XFF ... successful! Server : DB2 Common Server V9.5.0 Binding package automatically ... E:\DB2\9.5\SQLLIB\BND\DB2COMMON.BND ... successful! Binding package automatically ...

End time: Sun Apr 15 23:00:26 2012
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 ------ ------------------------------ 1 www.xifenfei.com 2 XIFENFEI 3 xifenfei 3 条记录已选择。
