who can help me to understand this scenario please. let say there is a client who have been using php as Backend, now he wants to merge his project from php to Spring knowing that he already has a full data and completly defined (mapping, primary key, tables), he export his data as sql (database.sql) so my question is how can we work and interact with this data in Spring Data ?
So you have the database export file(s), you create a new empty database and import those files there, configure your Spring Data to connect to the new db and stop using the Php app if you can (if you continue to use it you will have to somehow synchronize the two databases, more complicated)
In my project, I should receive data from the oracle and after processing it, write it to postgres, in my case, I need to use mybatis to communicate with the database. Can I connect to different databases in one project?(Postgres, Oracle) Have you faced such a situation?
If so, how do configure the datasourse? I need advice, thanks in advance. It will be great to see code examples
I have to use Laravel 5.7 with Oracle Cloud Database.
I actually have no idea how to do that. I have searched a lot but all instructions that I found are about connecting Laravel with local Oracle Database.
I have already created a database instance on Oracle Cloud and have no idea how to use instance's information in the cloud to make the connection.
Please, I need to know how to connect Laravel 5.7 with Oracle DB.
Thanks
Laravel does not officialy supports Oracle databases, but you can use a third party driver. Take a look on https://github.com/yajra/laravel-oci8
A webapp is using following configuration to store some data in DB:
spring.datasource.continueOnError=true
spring.datasource.driverClassName=org.h2.Driver
spring.datasource.url=jdbc:h2:mem:mydb
I was trying to reach this DB using H2 Console, but something is wrong. There are no tables even though I know they were created. I can also access any made up JDBC:URL like jdbc:h2:mem:fakeXYZ just as well with same result. What is goning on here? How can I see this DB tables and data?
Your JDBC URL specifies a named in-memory database which by default only will be available for connections from within the same virtual machine.
You can either change the URL to use a file-based database, or you will have to start a TCP server to allow for connections from other processes.
I have got a workspace in apex.oracle.com , Now , I want to connect to that database through JDBC from ubuntu-14.04 machine. please explain the steps , From where should I download the drivers and what should be the arguments in
DriverManager.getConnection();
step by step please. Thank you
You will not be able to connect to the database that's supporting the APEX instance on apex.oracle.com. If you are hosting your own instance, it's no different than connecting to any other Oracle database.A quick code snippet can be found here: http://www.java2s.com/Code/Java/Database-SQL-JDBC/TestOracleJDBCDriverInstallation.htm. You will need a password for the user/schema that you wish to connect to. If you don't have one, then talk to your DBA.
BTW, please remember that no production-type application and data should be used on the public APEX instance.
Maybe your problem is (or was) that you cannot connect via JDBC using the users you administered in your APEX workspace.
It seems to me that APEX users are not regular users for DB connections via JDBC. If my assumption is right, then you need to create database user with sufficient privileges to access the workspace tables.
