Need help in migrating data

edited Mar 3, 2014 12:00PM in PL/SQL (MOSC) 1 commentAnswered

Hi All,

I have a requirement to migrate and update only changed data from one schema to another  using plsql..

TABLEA:(SCHEMA A)

RUNID                      NAME                  VALUE

-----                      ----                  ------

HOST_dbname_20140221045343 NLS_LENGTH_SEMANTICS  CHAR

HOST_dbname_20140221045343 sga_max_size 7516192768

HOST_dbname_20140221045343 compatible            11.2.0

TABLEB:(SCHEMA

RUNID     NAME  VALUE

-----    ------ ------

we need to create package to insert the data first and then for future runs we have to update only the modified values for for eg if compatible is changed 11.2.0 to 11.0.0.0 then we need to update the changes

TableA data will be inserted by connecting to remote databases using dblink.finally the staging TABLE A data will be deleted after migrating to the target table TABLE  B.

Howdy, Stranger!
