Synonym for TEXT datatype (migration from postgres)

Question

Hi,
we want to migrate a Java application currently using a postgres database to Oracle with the least changes possible. One open question is the use of TEXT datatypes in postgres. We need some trick that the 2 statements in Oracle will work:
create table COFFEEStext
(COF_NAME varchar(32),
SUP_ID int,
PRICE float,
SALES text,
TOTAL float)
and
INSERT INTO MONALISA.COFFEESTEXT (
COF_NAME, SUP_ID, PRICE,
SALES, TOTAL)
VALUES ( 'arabica', 1, 2.35,
'good stuff', 2.35 );
I tried using a TYPE
CREATE OR REPLACE TYPE TEXT AS OBJECT (
COL VARCHAR2 (4000))
but then the INSERT statement does not work (Needs TEXT('good stuff') and easy select does not work as well).
I would need to define a synonym TEXT for VARCHAR2(4000) or CLOB (like the datatype REAL and FLOAT are synonyms for some NUMBER(x,y)).
How can I achieve this without changing the original statements from the Java Application?
Thanks, Michael

Answer 1

yes, that's true. But this means to change the code in the Application from datatype TEXT to VARCHAR2.
This is only an example, in realityt there are dozens of tables with their DDLs spread in the code, so I look for a solution without changing the DML and without changing the DDL of the application if possible!
The problem is that the same code still runs on postgres and the maintainer is not willing to make great changes everywhere.
