Oscar,

As an aside, I suggest you use Wonder’s features to implement the port, so you’re not stuck again with raw SQL.  I would also bet that raw SQL has nothing to do with performance, but more with either:

1.  A very complex query that cannot be translated into qualifiers (rare)
2.  A developer that didn’t understand what was possible

Fix it now, so you don’t have to fix it later!  I learned so much good stuff about ERXKey lately!

Hi all,
I'm migrating a few projects from Oracle to Postgresql, there are a lot straight RawRow for performance.

Raw rows or raw SQL?  Most raw row stuff can take a qualifier which removes the need for raw (custom) SQL.  You are using Wonder, right?


Now I'm facing the problem of changing every incompatibility like nvl for coalesce for example.
1. I will like to know the right way of doing a RawRow to use the JdbcPlugin for better cross databases

There might be some stuff in JDBCPlugin or in the SQLHelper family to make this easier, but it might be more trouble than it is worth unless you plan on migrating the projects again.


2. For my own problem is there any workaround instead of doing it by the long way.

I think you might be stuck with it.  Oracle is known for doing things its own way.

Appreciate any help
