I was hoping is there a way to create temporary tables using sequelize alike creating in RDBMS.

Being new to Azure SQL, I am already successfully JOINing my table with the table from the other database (by defining the CREATE EXTERNAL TABLE and the related things). However, some queries contain views from the other database, not the tables. How can I join my table with that external view? Is it possible at all? Or do I have to copy the code from the remote view and work directly with the external tables?
with create external table you can access a table or view :

Not:
DROP -> CREATE
I need:
COMPARE -> ALTER
I have a test and a production database, the data withing these two are different but the schemas should be the same.
I need something like a production script or a tool or a method which compare these two dbs schema and sync them. I'm coding in nodejs and the thing is I haven't used tools like an ORM or db-migrate, I've created the database using MYSQL-workbench and it costs a lot to write every alter query. there must be an easier way.
Using Apache Ignite, is it possible to extract the CREATE statement used to create the table? You can do this in MySQL with the SHOW CREATE TABLE x command for example.
I don't think dumping DML (database structure) is possible currently. Especially since CREATE TABLE is only one way of making tables in Ignite out of three.
However, you can query tables, schemas and indexes via JDBC metadata introspection feature.
I have a visio .vdx for the design of the my data warehouse with Lucidchart. Is there a way to generate redshift sql from that ?
What would be the best tool to work with Redshift data modeling ?
If those sql generator can generate tables for special visio stencil, like http://www.visualdatavault.com
Amazon Redshift is (mostly) compatible with PostgreSQL, so any tool that can introspect PostgreSQL tables should work with Redshift.
One things to note -- constraints and foreign keys are not enforced in Redshift.
I have a sqlite database in sqlite manager. I would like to create DB schema. How can i do that? Or is it best to use some software to create the DB Schema?
Need some suggestions and guidance.
there is a system table called sqlite_master. It contains the SQL CREATE statements for all objects.
So, all you need to do is to select all rows from this table, and run the sql statements.
You can also use Database->Export Database Structure, which will effectiveley do the same thing
there is only one database in SQLite for file.
probably you can create a new file and open that with sqlite manager.
certainly you can
go to Database menu + create new Database
