I've just found a version of what I need which works for MS SQL Server
2005 - it doesn't work for oracle though:-

UPDATE portlet
SET     portlet.description = param_exception.param_char_val
FROM portlet, param_exception
WHERE portlet.portlet_code = param_exception.portlet_code
and param_exception.param_char_val is not null
and param_name = 'portlet_title'

The sample statements below should work for you (They took quite a bit
of creating - is there an easy way to generate these statements)?

I want select * from portlet to go from

1,NULL

to

1,'Text To Be Transfered'

Hope I've been clear - many thanks ;-)

CREATE TABLE PORTLET
(
  PORTLET_CODE         VARCHAR2(20 BYTE)        NOT NULL,
  DESCRIPTION          VARCHAR2(50 BYTE),
)

INSERT INTO  PORTLET (
   PORTLET_CODE,  DESCRIPTION )
VALUES ( 1,NULL );

ALTER TABLE  PARAM_EXCEPTION
 DROP PRIMARY KEY CASCADE;
DROP TABLE RMGTEST.PARAM_EXCEPTION CASCADE CONSTRAINTS;

CREATE TABLE  PARAM_EXCEPTION
(
  PORTLET_CODE    VARCHAR2(20 BYTE)             NOT NULL,
  PARAM_NAME      VARCHAR2(20 BYTE)             NOT NULL,
  PARAM_CHAR_VAL  VARCHAR2(4000 BYTE),
) ;


INSERT INTO  PARAM_EXCEPTION (
   PORTAL_TYPE, STRUCTURE_CODE, OWNER_TYPE,
   OWNER, PORTLET_CODE, PARAM_NAME,
   PARAM_NUM_VAL, PARAM_CHAR_VAL, PARAM_DATE_VAL,
   PARAM_BOOL_VAL)
VALUES ( 1,'Description','Text To Be Transfered'  );

INSERT INTO  PARAM_EXCEPTION (
   PORTAL_TYPE, STRUCTURE_CODE, OWNER_TYPE,
   OWNER, PORTLET_CODE, PARAM_NAME,
   PARAM_NUM_VAL, PARAM_CHAR_VAL, PARAM_DATE_VAL,
   PARAM_BOOL_VAL)
VALUES ( 2,'Description2','Text Not To Be Transfered'  );
