Raw Normal View History

Update to ora2pg 1.2.
2001-05-13 10:10:00 +08:00
2001 05 09 - Initial version 1.0
2001 05 09 - Version 1.1
- Add table grant extraction based on group. Oracle ROLES are groups in PG
2001 05 11 - Version 1.2
Here the latest version and first working release of Ora2Pg a tool to export Oracle database to PostgreSQL. It currently dump the database schema (tables, views, sequences, indexes, grants), with primary, unique and foreign keys into PostgreSQL syntax without editing the SQL code generated. You can dump only a particular schema from the Oracle database. Functions, procedures and triggers with SQL or PLSQL code generated must be reviewed to match the PostgreSQL syntax. Some usefull recommandation on porting Oracle to PostgreSQL can be found at http://techdocs.postgresql.org/ under the "Converting from other Databases to PostgreSQL" Oracle part. I just notice one thing more is that the trunc() function in Oracle is the same for number or date so be carefull when porting to PostgreSQL to use trunc() for number and date_trunc() for date. I will add more precision in type NUMBER conversion based on length to match as closest as possible all rich PostgreSQL numerics type. But it seems not to be urgent as it seems that Oracle DBAs only create number with length 22 (default) Space seems not to be their problem... Gilles DAROLD
