Flask-SQLAlchemy data types

Question

I'm starting to use the Flask-SQLAlchemy package in my web project and am wondering about the data type usage. It appears that the package can use any of the SQL standard types , but also seems to have a few of it's own ( String ) that are likely recasts of one of the standard types. The notation difference to distinguish these seems to be caps ( INTEGER ) for the standard types and a starting cap ( Integer ) for the package specific types.

Does anyone know where they do an overview of all the permissible types - I'm mainly interested in understanding the package specific ones and their characteristics. I've been reading the documentation, and may have missed it. Otherwise, I know I can just keep it simple and use all standard types.

Answer 1

您在文档的右侧，只需要跳到Column and Datatypes-Generic Types文档即可 。

Answer 2

This page provides an overview of the types implemented in SQLAlchemy.

You can also use the flask-sqlalchemy.SQLAlchemy class to look through the available data types.
