pandas is a Python package that provides fast, flexible, and expressive data structures designed to make working with "relational" or "labeled" data both easy and intuitive. It aims to be the fundamental high-level building block for doing practical, real world data analysis in Python. Additionally, it has the broader goal of becoming the most powerful and flexible open source data analysis / manipulation tool available in any language. It is already well on its way towards this goal.


SQLAlchemy is the Python SQL toolkit and Object Relational Mapper that gives application developers the full power and flexibility of SQL. SQLAlchemy provides a full suite of well known enterprise-level persistence patterns, designed for efficient and high-performing database access, adapted into a simple and Pythonic domain language.


sql_to_ibis is a Python package that translates SQL syntax into ibis expressions. This allows users to use one unified SQL dialect to target many different backends, even those that don't traditionally support SQL.

A good use case would be ease of migration between databases or backends. Suppose you were moving from SQLite to MySQL or from PostgresSQL to BigQuery. These frameworks all have very subtle differences in SQL dialects, but with sql_to_ibis, these differences are automatically translated in Ibis.

Another good use case is pandas, which has no SQL support at all for querying a dataframe. With sql_to_ibis this is made possible.

For example,

import ibis.backends.pandas
import pandas
import sql_to_ibis

df = pandas.DataFrame({"column1": [1, 2, 3], "column2": ["4", "5", "6"]})
ibis_table = ibis.backends.pandas.from_dataframe(
    df, name="my_table", client=ibis.backends.pandas.PandasClient({})
sql_to_ibis.register_temp_table(ibis_table, "my_table")
    "select column1, cast(column2 as integer) + 1 as my_col2 from my_table"

This would output a dataframe that looks like:

column1 my_col2
1 5
2 6
3 7
