Is it possible to reverse engineer an oracle database using flyway?
I need to dump all the schema's from a database, including all objects, but don't need the data.
I found this, but it's from 4 years ago
Reverse engineering an existing database with flywaydb?
Could someone confirm if that's still the case and you can't reverse engineer an oracle database with flyway?
Thanks
Oracle SQL Developer can achieve this. You can find the feature in Tools/Database Export menu. Here is the docs page.

Is it possible to compare data from an Oracle DB and an Azure SQL DB. The data should be the same in each but I want to find out is there a way to check and confirm this?
I'm thinking maybe a Java application that could check and compare the same row of each application, or check totals/counts. Or is there a more straight forward way? Any advice appreciated.
Maybe you should give us more info about the story of the database.
Have you created an Azure SQL Database from an Oracle DB or the other way around?
My approach would be:
Use SSMA to translate the Oracle database to a SQL Server database.
Now use any compare database you find online (there are many) and compare the two.
If you tell me more about the story of the database I can understand better.
I want to know oracle 12 c Document Store RDBMS VS NoSql
I think that the Oracle 12c DocumentStore works similarly to MondoDB(schemaless-database).
But today I heard a shocking story.
Oracle12C database works similar to RDBMS. oracle12c document-store create a temporary schema and store data in database. So Oracle12c DocumentStore is not NoSql. Also, how to use Nosql as RDBMS service without separate installation? It just provides similar functionality, not Nosql.
and I said "That's one feature built into the ORACLE12C version, NoSql is correct."
No conclusion, I don't think I'm wrong, but I ask a question because I wanted to get an accurate answer. Please provide a answer or related documentation.
I know this question is similar to another one, but I have now tried both the Oracle data provider and the Devart (dotConnect) provider, and cannot get either combination to work well with our Oracle 11g database and the Power Tools "reverse engineer code first" feature.
With the Oracle provider, there was no way to specify a schema or subset of the database, and it cranked out almost 3,000 entity classes, even though the connection was specific to the target application. It grabbed all the Oracle system tables, etc., along with the application data tables.
With the Devart provider, I still could not specify WHAT to generate, and ended up having to kill it off after running for almost a day.
Anyone know how to get this stuff working with Oracle?
We have answered you about dotConnect for Oracle (Entity Developer) at http://forums.devart.com/viewtopic.php?f=1&t=27520.
I am developing an ASP.net application with Access database. I need to convert this Access database to Oracle. How can I do that?
I saw two options
Migrating the access database to Oracle through MIGRATION WIZARD in SQL developer
In Oracle, just creating a new connection with existing MS Access database and then converting to oracle.
Kindly let me know the best solution for this
thanks in advance,
Arjun
The two choices you proffer could be rewritten like this:
Use an automated tool written by experts
Do it the hard way and figure it out for myself
This is a personal, even philosophical, choice. Do you need to get the task done quickly? Or do you want to learn something along the way?
TRY IT and then tell us.
My experience integrating all things oracle with all things microsoft has always been complicated, and a lot of manual intervention was required.
It also depends on the complexity of your existing access database, if it's only one table, then you can grab that table sql, correct it for nvarchar -> varchar2 fields and datapump the data into oracle.
If Access has 1000+ tables I would suggest getting a professional to do it. Any reasonable dba should handle it no problem.
Please check the solution at Insert into from ms access to oracle db
You can customize the code based on your requirement. You can bundle the whole code into one class and prepare it as exe application.
I have a Microsoft SQL Server database(tables, relationships and data).
But now I want an exact same copy of this database in Oracle.
I was thinking there may be some sort of a tool or converter that could generate Oracle sql scripts that I could run to create and populate my new Oracle database.
Is this kind of thing possible?
And how can I achieve this ?
Your best bet is to use a DB modelling tool which can reverse engineer your SQL Server database and then generate a script to recreate it in Oracle.
DB Designer Fork can do this for you and is Open Source.
