Py-Linq-SQL

A Python module used for interacting with sql database using LINQ syntax. The project is under EUPL License v1.2.

Py-linq-sql allows you to go from (SQLAlchemy using direct text query):

conn.execute(
  text(
    """SELECT "data"-&gt;'obj'-&gt;'name' as name """
    """FROM "objects" """
    """WHERE "data"-&gt;'obj'-&gt;&gt;'name' == "earth" """
    """AND CAST("data"-&gt;'obj'-&gt;'mass' &gt; 0.5 AS Decimal) """
    """LIMIT 1 OFFSET 2"""
  )
)

to the safer and easier to read:

sqle = (
  SQLEnumerable(conn, "objects")  # objects is the name of the table
  .select(lambda x: {"name": x.data.obj.name})  # data is a JSONB column
  .where(lambda x: x.data.obj.mass &gt; 0.5)  # data is a JSONB column
  .skip(2)
  .take(1)  # this is the last part of the query, till there nothing is executed
  .execute()  # now we ask for the whole query to be executed on the DB server
)

Pro :

all the query expression are expressed in pure python expression
easy support of JSON database using a simple object notation
very difficult to have an SQL injection (only the names of the tables are strings)
standardized syntax/API of LINQ (used in java, C# and many .net languages)
very fast: even very long and complex queries are executed in one single query on the server
no need to define a class for every table in the DB as you would do in an ORM here you write query assuming the tables, columns and fields exist, if not then you get a clear error about it
results are pylinq Enumerable that are themselves queryable in same way but locally
all kinds of join (inner, outer and full, with or without intersections) are easy to use and combine with any kind of query

Cons :

currently only support PostgresQL

Any feedback is welcome see Contributing.
