I woululd like to use sequelize as my ORM in a web app I am building. The app will be based on NodeJS - Express for constructing and MySQL as its relational database. What I haven't found anywhere on documentaino or on the net, is how to declare in sequelize models the "Views" that exist in my MySQL Database....
Is the only way to manually construct the query SQL? Thanks
You can use Node ORM2, which has support for MySQL views as well.
Try at

So I have a multi-tenant application. So each tenant has their own schema and there is a common schema between all of them. The common database is created and maintained programmatically by sequelize using the folders and files created by sequelize init. This allows me to use ORM functions such as findAll or findByPK for the common schema but to do any CRUD on one of the tenants schemas I use a mysql connection with raw queries. My question is: Is it possible interface with the tenants schemas using ORM? Like can I change the current default schema being used by sequelize so that I can use findAll for a tenants schema?
Please let me know if this question is confusing and I will try ask it in a different way.
I just convert database backend from sqlite to mysql.
But When I test my feature in project is ERROR.
NotSupportedError at /filter/
intersection is not supported on this database backend.
In my view.py have Django ORM Union, Intersection. I think this is the troublemakers. Why It can't use Union, Intersection in MySql Backend.
I try to fix it. But I don't know how. Please Help me T^T
Because the MySQL backend does not support intersection. From Django source:
https://github.com/django/django/blob/a906c9898284a9aecb5f48bdc534e9c1273864a6/django/db/backends/mysql/features.py
supports_select_intersection = False
You can switch to another database backend which supports intersection, or rewrite your query in a way that doesn't require intersections.
Based on some researches, I'm sure Laravel supports MySQL, SQLite, PostgreSQL by default. I mean we can just simply replace one of those database names with this:
Well I have two related questions:
Isn't there any list of all databases that Laravel supports by defaul? For example what about SQL Server? Can I just replace sqlserver with mysql, then does it work? In other word Does Laravel know sqlserver by default?
How can I add a new database to Laravel? For example (suppose sqlserver is not supported in Laraver by defaul) so how can I add sqlserver to Laravel?
Currently, Laravel 5.3 supports four databases:
MySQL
Postgres
SQLite
SQL Server (Driver 'sqlsrv')
Refer Laravel Docs - Database
Adding a new Database will always going to take great amount of efforts. Because you will need to write at least whole DB Façade (Forget about the Eloquent ORM Support) to maintain the cleanliness and ease of Laravel Framework.
This includes basic CRUD , database structures & Schema and Eloquent model and Query builder with support for your Database.
As Laravel supports most used SQL and No-SQL Databases by default, there are plenty of open source libraries for other databases, too.
For Example, Laravel MongoDB is a good open source library built using Laravel Core APIs.
Am able to connect to database in node.js but i wonder where to create, store and retrieve my tables .
Try using sequelize js ORM,
http://docs.sequelizejs.com/en/latest/docs/schema/
This module can be used for defining the tables,
By the way no need to navicat for this, in case you have specific requirement please brief here.
I tried using sequelize and node-orm as well - but is there a way to reuse existing mysql schema? I Have a db schema defined with tables in mysql and wanted to use this with my node.js app (using express). So, I don't have to write all the define methods of defining tables again.
Any help appreciated...
I went through bunch of stackoverflow questions already such as: Which ORM should I use for Node.js and MySQL?
Thanks,
JP
Checkout bookshelf.js, it doesn't require that you define the schema in the model layer.
