DB2数据库序列的移植方法

1. 生成以下语句，得到源数据库序列的当前值：

www.2cto.com

Sql代码

SELECT

'SELECT ''CREATE SEQUENCE ' || seqname || ' START WITH '' || ' || seqname ||

'.nextval from sysibm.sysdummy1'

FROM

syscat.sequences

WHERE

seqtype='S'

AND seqschema=CURRENT schema

www.2cto.com

2. 根据第一步生成的语句，逐句执行产生建立目的数据库序列的SQL语句，如：

Sql代码

SELECT 'CREATE SEQUENCE SEQ_CCP_CM_CLIENT_INFO START WITH ' || SEQ_CCP_CM_CLIENT_INFO.nextval from sysibm.sysdummy1

SELECT 'CREATE SEQUENCE SEQ_CCP_MM_BRODCAST_INFO START WITH ' || SEQ_CCP_MM_BRODCAST_INFO.nextval from sysibm.sysdummy1

SELECT 'CREATE SEQUENCE SEQ_CCP_MM_INDUSTRY_INFO START WITH ' || SEQ_CCP_MM_INDUSTRY_INFO.nextval from sysibm.sysdummy1

SELECT 'CREATE SEQUENCE SEQ_CCP_MM_WARN_LEVEL START WITH ' || SEQ_CCP_MM_WARN_LEVEL.nextval from sysibm.sysdummy1

SELECT 'CREATE SEQUENCE SEQ_CCP_RM_BACK_PLAN START WITH ' || SEQ_CCP_RM_BACK_PLAN.nextval from sysibm.sysdummy1

SELECT 'CREATE SEQUENCE SEQ_CCP_RM_CERT_INFO START WITH ' || SEQ_CCP_RM_CERT_INFO.nextval from sysibm.sysdummy1

SELECT 'CREATE SEQUENCE SEQ_CCP_RM_CLNT_RELATION START WITH ' || SEQ_CCP_RM_CLNT_RELATION.nextval from sysibm.sysdummy1

3. 执行第二步生成的语句。应该还可行列自动化一点，目前没时间测试！
