DB2 时间转换

create function ts_fmt(TS timestamp, fmt varchar(20)) returns varchar(50) return with tmp (dd,mm,yyyy,hh,mi,ss,nnnnnn) as ( select substr( digits (day(TS)),9), substr( digits (month(TS)),9) , rtrim(char(year(TS))) , substr( digits (hour(TS)),9), substr( digits (minute(TS)),9), substr( digits (second(TS)),9), rtrim(char(microsecond(TS))) from sysibm.sysdummy1 ) select case fmt when 'yyyymmdd' then yyyy || mm || dd when 'mm/dd/yyyy' then mm || '/' || dd || '/' || yyyy when 'yyyy/dd/mm hh:mi:ss' then yyyy || '/' || mm || '/' || dd || ' ' || hh || ':' || mi || ':' || ss when 'nnnnnn' then nnnnnn else 'date format ' || coalesce(fmt,' ') || ' not recognized.' end from tmp 使用例句： update t_attachment as a set a.attach_path=(select '/'||rtrim(char(apply_com_id))||'/'||rtrim(char(ts_fmt(apply_date,'yyyymmdd')))||'/' from t_rmbs_claim as c where a.claim_id=c.claim_id)||rtrim(a.attach_path) where exists (select 1 from t_rmbs_claim as tc where tc.claim_id=a.claim_id);

DB2 restore Redirect

(1)db2 restore db EFINANCE incremental from /db2/eFinance091228  taken at 200912282115 on /db2/eFinanceWJ28 into EFINAN28 logtarget /db2/eFinanceWJ28 redirect generate script  restore.clp
说明：EFINANCE 为备份前的数据库名称  EFINAN28 为回复后的数据库名称 /db2/eFinance091228备份文件存放的路径  /db2/eFinanceWJ28为还原后日志存放路径以及还原后数据库文件路径。

(2)db2 -tvf  restore.clp
如果需要重新指定表空间的路径请修改该文件
