How to create database using knex npm?
Here it is MYSQL query
create database 'test'
I want to convert this query using knex.
There is no special API for creating DB in knex, probably because knex usually connects to already created DB and to be honest database creation is pretty rare operation.
Npm package knex-db-manager (https://vincit.github.io/knex-db-manager/) can do also database maintenance tasks and has separate superuser and normal user connection.

There are multiple table in my Oracle DB that I plan to migrate into Mysql db.
The way I imagine is that
1.Go to each oracle table to execute some sort of cmd to generate the create statement that I can paste in my Mysql prompt.
However, due to my newbie knowledge in db, Does it really exist such simple cmd to do that?
If yes, can I even execute this idea batchly?
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.
I have a knex powered app that once I clone from github, I can run yarn migrate:latest to get the database up to date.
The problem is, in some cases, like a new developer, the database might not yet exist.
What is the right way to first create the database? Do I need to do that outside of KNEX or is there a KNEX CLI/Migration type of commend for this need?
Thats not supported (knex 0.14.2). You need to create database + db users in advance. If you like to have node library helping in that knex-db-manager is knex based helper lib for database management like creating DBs and db owner user etc.
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.
