![]() ![]() The metadata contains the table name, column names with the type, and schema. metadata = db.MetaData() #extracting the metadataĭivision= db.Table('divisions', metadata, autoload=True, You can produce metadata using SQLAlchemy’s `MetaData()` function. To create a table object, we need to provide table names and metadata. You can take SQL Fundamentals and Python Fundamentals skill track to build a strong base. This SQLAlchemy tutorial assumes that you understand the fundamentals of Python and SQL. If you want to connect PostgreSQL, MySQL, Oracle, and Microsoft SQL Server databases, check out engine configuration for smooth connectivity to the server. from sqlalchemy as dbĮngine = db.create_engine("sqlite:///european_database.sqlite") ![]() We will use the ‘conn’ object to run all types of SQL queries. ![]() Then, we will create a connection object by connecting the engine. We will be using the European Football SQLite database from Kaggle, and it has two tables: divisions and matchs.įirst, we will create SQLite engine objects using ‘create_object’ and pass the location address of the database. In this section, we will learn to connect SQLite databases, create table objects, and use them to run the SQL query. Let’s check if the package is successfully installed: > import sqlalchemyĮxcellent, we have successfully installed SQLAlchemy version 1.4.41. In case, you are using the Anaconda distribution of Python, try to enter the command in conda terminal: conda install -c anaconda sqlalchemy You can install SQLAlchemy using the Python Package Manager (pip): pip install sqlalchemy It is fairly easy to install the package and get started with coding. In simple words, it allows users to connect databases using Python language, run SQL queries using object-based programming, and streamline the workflow. Working with objects provides developers flexibility and allows them to build high-performance SQL-based applications. You can write a query in the form of a string or chain Python objects for similar queries. SQLAlchemy is the Python SQL toolkit that allows developers to access and manage SQL databases using Pythonic domain language. ![]()
