I dont have any idea how create new table "product" in postgresql.
In mysql everythink is good
You can with do it manually by running heroku pg:psql and then running the appropriate SQL statements. Or you can use a migration framework in your app.
For more information on running database migrations see the Heroku docs.

I have all my liquibase changelogs with respect to MySQL database now we are planning to move to MSSQL so when I try to run the existing changelogs which is working fine for MySQL is failing for MSSQL. Is there any configuration in liquibase to handle database migration?
getting below error when I run changelogs on MSSQL
addAfterColumn is not allowed on mssql
you can use dbms attribute and configure changelogs to be executed only on given databases.
In my current project, I am doing migration from Oracle to Azure SQL Server. Right now, we need to integrate both database working with same queries. Depending on what I have on my configuration, project will connect with Oracle or Azure SQL.
Problem is, there are some queries that are not compatible for both database types. For instance, nextval works for Oracle, but not with Azure SQL:
In Oracle:
... values(unique_id_seq.nextval ...
In Azure SQL:
... values(NEXT VALUE FOR unique_id_seq, ...
Therefore, I think I will need to create two different queries and my project should know which database I am loading and it should map to correct query. Is this possible to achieve in springboot? I am pretty new to springboot..
(One of my co-worker said If possible try to convert query into HQL or add the mapping entity, instead of creating separate queries., but I am not sure what this means.)
Try using Spring Boot with Hibernate.
I searched the docs and web for it and could not find the answer.
I'm trying to create a mysql db from datanucleus on startup, I don't mean the CreateSchema option but the create database command.
Is there an option to do it rather then from the mysql server ?
I'm using datanucleus 4.1,
Thanks .
When we write an application, we also write migrations for database schema and data, we use liquibase for that.
For example I am deploying an application locally as developer on my machine, application uses elasticsearch, but before adding some data I need to execute some query/mappings.
So, I want to add that query/mappings to some files, so, when another developer will deploy application on his machine, that query will be executed automatically.
What tools/library are using for migrations ElasticSearch schema?
I created a long time ago a project I'm still maintaining which creates an index with all settings and mappings if it does not exist at startup.
elasticsearch-beyonder is available at https://github.com/dadoonet/elasticsearch-beyonder.
For now, it works only with a TransportClient but I'm planning to add support for the Java REST Client as well.
Is there any available/aiding tool in java/Spring to do read data from Oracle (old/existing table structure), do some transformation and basically send to Spring-data-REST exposed MySQL database(new table structure).
Basically, want to build a Spring boot application/service which does the same.
P.S.,we have a audit log table in Oracle which we want to use it to drive/sync from Oracle to MySQL.
Does Flyway support this?
Thanks
