# Perseus MicrORM
Majormode Perseus MicrORM Python Library is a small, little, mini, tiny, micro Object-Relational Mapping (ORM).
MicrORM is not a object-relational mapping in the sense it maps Pyth objects to a Relational DataBase Management System (RDBMS), but in the sense it maps results of SQL queries, executed on a RDBMS, to Python objects.
## Installation
To install [Perseus MicrORM Python Library](https://github.com/dcaune/perseus-microrm-python-library), simply enter the follow command line:
``` shell
pip install perseus-microrm-library
```
## Usage
``` python
import uuid
from majormode.perseus.utils import cast
from majormode.perseus.utils.rdbms import RdbmsConnection
RDBMS_CONNECTION_PROPERTIES = {
None: {
'rdbms_hostname': 'localhost',
'rdbms_port': 5432,
'rdbms_database_name': 'foo',
'rdbms_account_username': 'dbo',
'rdbms_account_password': ''
}
}
PLACE_IDS = [
uuid.UUID('54879ffc-a1ec-11e8-85bd-0008a20c190f'),
uuid.UUID('9025d1c8-a1ec-11e8-9e29-0007cb040bcc')
]
with RdbmsConnection.acquire_connection(
RDBMS_CONNECTION_PROPERTIES,
auto_commit=False,
connection=None) as connection:
cursor = connection.execute(
"""
SELECT place_id,
ST_X(location) AS longitude,
ST_Y(location) AS latitude,
ST_Z(location) AS altitude,
accuracy,

FROM place
WHERE place_id IN %[place_ids]s
""",
{
'place_ids': PLACE_IDS
})
rows = cursor.fetch_all()
places = [
row.get_object({
'place_id': cast.string_to_uuid,
'creation_time': cast.string_to_timestamp})
for row in cursor.fetch_all()]
for place in places:
print(place.place_id, place.longitude, place.latitude)
