EA1: Diff Wizard Issues

Question

The schema difference tool now seems to work reliably, but I find it very limited. The main limitations are
1 it is 'one-way'.
It doesn't show you objects in the target schema which aren't in the source schema. I think this is by design - the aim seems to be to provide a tool for converting adding one schema to another. I had hoped for more of a 'schema merge' tool (see below).
2 You can't see the actual differences.
For tables you can see the ddl to change the table, but you can't see what was there in the first place.
For PL/SQL objects, the 'create or replace syntax' means you can't see what the differences were at all.
This is what I would like to see.
As I said above, I would like a schema merge tool, just like the code merge tool in JDeveloper and many other development tools.
1) The ability to view the two schemas side by side with differences highlighted.
2) The ability to create a merged schema by selecting differences from either side
3) Generate DDL to go from either schema to the merged schema.
I used to use something similar years ago with ERwin http://www.ca.com/us/products/product.aspx?id=260
BTW. How do you post proper hyper links in the forum?

Answer 1

An example of an empty line? If you insist... ;-)
Delimiting the code blocks with *.
Here's the contents of an SQL tab in the base schema:
*  CREATE OR REPLACE FORCE VIEW "VW_AFI_CNO" ("AFICNO_ID", "AFICNO_CODIGO", "GENTRADUC_TRADUCCION", "GENIDIOMA_ID") AS
  SELECT AFI_CNO.AFICNO_ID, AFI_CNO.AFICNO_CODIGO, GEN_TRADUCCIONES.GENTRADUC_TRADUCCION, GEN_TRADUCCIONES.GENIDIOMA_ID
FROM   AFI_CNO, GEN_TRADUCCIONES
WHERE  GEN_TRADUCCIONES.GENEXPRES_ID(+) = AFI_CNO.GENEXPRES_ID
Here's the contents in the destination schema:
*  CREATE OR REPLACE FORCE VIEW "VW_AFI_CNO" ("AFICNO_ID", "AFICNO_CODIGO", "GENTRADUC_TRADUCCION", "GENIDIOMA_ID") AS
  SELECT AFI_CNO.AFICNO_ID, AFI_CNO.AFICNO_CODIGO, GEN_TRADUCCIONES.GENTRADUC_TRADUCCION, GEN_TRADUCCIONES.GENIDIOMA_ID
FROM   AFI_CNO, GEN_TRADUCCIONES
WHERE  GEN_TRADUCCIONES.GENEXPRES_ID(+) = AFI_CNO.GENEXPRES_ID
Here's the comparison result:
--  DDL for View VW_AFI_CNO
  CREATE OR REPLACE VIEW "VW_AFI_CNO" ("AFICNO_ID", "AFICNO_CODIGO", "GENTRADUC_TRADUCCION", "GENIDIOMA_ID") AS
  SELECT AFI_CNO.AFICNO_ID, AFI_CNO.AFICNO_CODIGO, GEN_TRADUCCIONES.GENTRADUC_TRADUCCION, GEN_TRADUCCIONES.GENIDIOMA_ID
FROM   AFI_CNO, GEN_TRADUCCIONES
WHERE  GEN_TRADUCCIONES.GENEXPRES_ID(+) = AFI_CNO.GENEXPRES_ID
