Sometimes in University I found bold young guy saying something like:
I will reimplement this in machine language because is faster
I will reimplement this xyz C function by my own
My program crash, I think there is a bug in HP UNIX socket implementation
I will ge rid of this Java Garbage Collector because it is too slow. I will reimplement all the code in my C++ routine.
Belive me: your code is doomed. A full list of guys have already done your same code, found a million bugs and corrected it in the tool you want to replace because they are shitty slow, to your eyes.
I feel your pain because I made your same mistake. Keep reading.

Oracle SQL Developer is full of nice feature, damned by a overwhelming options pane, like the one I will describe to you right now.
I will show here a very fast way of comparing different database and auto-generate migration script.
- Reverse engineer the source database using Oracle Data Modeler
- Now select the right arrow shown below:
- Select the destination datasource (more here) when asked.
- The compare pane will enable you to compare the databases.
But the default options will also use schema name to detect different object, so you will not get what you want in every scenario.
In 50% of my daily job, schema are different, so you must select the options below to fix it:
Select “Options” and then “Compare options”. Then de-select “Use schema property” like suggested below:
- Push the “Sync new object”. Then push the “DLL Preview” button and inspect the generated database.
- Bonus: by default the tool will not include tables to drop. Inspect the two pane ad check the table you want to drop in the left pane.
- Refrain launching the script without proper testing. You are migrating your valuable data.
