I have three different data base regions

Question

Help is Greatly appreciated.
I have three different databases - development, QA and Production.
my requirement --I have to insert 20 new records  into "scott.PERMANENT" table 
2)In the Developemnt,QA both regions in the "scott.PERMANENT" table , 3 records are already presnet in the above new 20 records. 3)In the Production database , i dont have any data and have to insert all of the records.
So inorder to insert the data i have to use the same script in all the regions meaning i have to iclude all the 20 new records in the insert script ,but based on the region name it should check and insert those records .
could anyone please kindly give me an idea how to check the region name and insert.
Your help is kindly appreciated.

2)In the Developemnt,QA both regions in the "scott.PERMANENT" table , 3 records are already presnet in the above new 20 records. 3)In the Production database , i dont have any data and have to insert all of the records.
So inorder to insert the data i have to use the same script in all the regions meaning i have to iclude all the 20 new records in the insert script ,but based on the region name it should check and insert those records .Use MERGE instead of INSERT. If you're using Oracle 10 or higher, then you don't even need a WHEN MATCHED clause; if you only have a WHEN NOT MATCHED clause, it will simply ignore the rows that you said to add but already exist.
If the columns have unique constraints, you can also INSERT all the data, and use an error logging clause
I hope this answers your question.
If not, post a complete test script that people can run to re-create the problem and test their ideas.
For example:
-- In all 3 databases, the permanent table looks like this:
CREATE TABLE permanent ...
-- In Production, where it has no rows, I could populate it like this:
INSERT INTO permanent ...
-- This is how I want the table to look in all 3 databases when everything is finished.
-- But in Development and QA, the table does have some rows already, like this:
TRUNCATE TABLE  permanent;
INSERT INTO permanent ...
-- What statement(s) would get the table to the finished state regardless of how it starts?Always say which version of Oracle you're using (e.g., 11.2.0.2.0).
