I am trying to connect JHipster's MySQL database with a HIVE database so that JHipster can be receive data from HIVE tables. I want to ask you what is the best approach for this problem as I have just began using JHipster.
Thank you !
what do you mean when you say JHipster's MySQL database with a HIVE database? I asume that you want to use the MySQL database for authentification and authorization and then for diferent bussines logic you will want to retrive data from HIVE. If you are using your JHipster project with a relational database, then jhipster is using spring data jpa in order to access the database. Since HIVE is a NoSQL database, my recomandation it will be to have a look at spring-hadoop for an easy access on HIVE database and create a service which is macking use of sopring-data-jpa.

Is it possible to create a MySQL Schema from a running AWS-based RDS database? I am a newbie and not sure whether there is a tool like what is available in MySQL workbench type dashboard to create schema at ease?
I am also new to this but I recently created a MYSQL database on AWS RDS.
(I am new to MySQL and AWS).
The answer is yes, we can create schemas. However, as much as I understand, there is no concept of schema in MySQL. There is one database where you create the different database objects and then we just query those using one user or the other.
Edit:: Database and Schema are same thing as per the comments. So yes, we can create schemas and then users to access them.
Anyways, you can use the MySQL workbench to connect your AWS RDS database.
Or you can do the same using any coding language. For both the above options, make sure your database is created with 'Publicly accessible' option enabled.
Refer to this - https://aws.amazon.com/getting-started/hands-on/create-mysql-db/
If you follow all steps, your database on AWS should work like one installed locally on your machine.
I have a MySQL file that I would like to explore using sqltool. I do not want to deploy a MySQL database because I only need to run a few queries on the data; I do not need persistence.
I understand that sqltool will allow me to create an in-memory database and run queries on it. This is perfect for my use-case, but how do I make it accept the MySQL dialect of SQL?
Additionally, is the process the same for other dialects such as Postgres SQL?
You need to deploy a MySQL database.
The HSQLDB SqlTool allows you to connect to a MySQL server using the MySQL JDBC driver, or to any other database server such as PostgreSQL using the relevant JDBC driver.
The SqlTool also allows you to create an in-memory database when used with HSQLDB, but this type of database is different from a MySQL database.
now I'm working on hybrid mobile application with SQLite. This application just only retrieve the data from database. The data come from MYSQL database, but I want to store the data into local storage which is SQLite so when the user don't have the internet, they can retrieve the data from local storage. So,is there a way to connect mysql db and sqlite? I have been following the tutorial from this site
but I do not know how to connect sqlite with mysql db. So,anyone can help me to solve my problem ?
You can connect using a API that give a response as a JSON and store and access those using ionic local storage
Or you can design a server side code using node js and connect to db
I need to select some data from WX2 Database and put it in MYSQL DB.
Can any one help me on this?
Is ODBC.ini configuration will work for the mysql database to connect to WX2 database?
Thanks
To access the data in Kognitio you could use the ODBC driver to retrieve it, or for better performance use the bulk unloader utilities to export it as CSV, which you could then load into MySQL.
If you were going the other way round, pulling data FROM MySQL TO Kognitio, you could bulk unload as CSV from MySQL then bulk load into Kognitio, or you could use the External Table functionality of version 8 to access MySQL tables on demand from Kognitio via an ODBC connector.
The documentation covers off all these approaches.
I need to migrate some tables in mysql db to oracle db.
Do you now any tutorial to learn about this migration?
Thanks
You can connect to the MySQL instance from Oracle using Oracle's database link - this link details making the connection from Oracle to MySQL.
Bearing in mind that the MySQL account you use to create the connection will determine access to MySQL data, once the link is created you can work within Oracle to select data from the MySQL tables into the Oracle tables without a need for scripts and such.
Find an ETL tool like Informatica or SSIS to help you. Oracle's Migration Workbench might be the perfect choice, since you're already using Oracle.
