DB2数据库序列的移植方法

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：

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

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！
