Good a day to everyone,
We have got a big database with 504 datafiles within, and I have got create a physical standby for it, ok, it's easy but difficult (of course, to me because of poor SQL) to convert string.
We have got datafile location as following
Primary: +DATA/wrhprim/datafile/data.279.907075777
DG: +DATA/wrhstd/datafile/data.279.907075777
The simply SQL to generate file_name location is
select 'set newname for datafile '''||file_name||''' to '''||''||file_name||''''||';'
from dba_data_files where rownum<=10;
and the simply sql to get wrhprim is:
SELECT SUBSTR(file_name,7,7) from dba_data_files where rownum<=10;
But, I have no idea to put the convert string into one of SQL (wrhprim to wrhstd)
May you help me, thank you very much
