Utilização

Alguns exemplos de uso.

Conexão básica

from pyDbOracle.database import Database
str_conn = 'oracle://<USER>:<PASS>@<HOST>:<PORT>/<INSTANCE>'
db = Database(str_conn)
db.info()

Conexão em banco com RAC

from pyDbOracle.database import Database
str_conn = 'oracle://<USER>:<PASS>@<HOST>:<PORT>/<INSTANCE>?threaded=True'
db = Database(str_conn)
db.info()

Conexão definindo charset

from pyDbOracle.database import Database
str_conn = 'oracle://<USER>:<PASS>@<HOST>:<PORT>/<INSTANCE>?encoding=utf-8'
db = Database(str_conn)
db.info()

Executando queries

from pyDbOracle.database import Database
str_conn = 'oracle://<USER>:<PASS>@<HOST>:<PORT>/<INSTANCE>'
db = Database(str_conn)
command = 'SELECT INSTANCE_NAME FROM V$INSTANCE'
data = db.get(command=command)
print(data)
# {'instance_name': 'PROD'}

Executando queries com filtros

from pyDbOracle.database import Database
str_conn = 'oracle://<USER>:<PASS>@<HOST>:<PORT>/<INSTANCE>'
db = Database(str_conn)
command = 'SELECT INSTANCE_NAME FROM V$INSTANCE WHERE HOST = :host'
params = dict(host='MEUHOST')
data = db.get(command=command, params=params)
print(data)
# {'instance_name': 'PROD'}

Executandos Inserts, Updates ou Deletes

Quando precisar executar um comando do tipo insert, update ou delete, rodar o metodo run

from pyDbOracle.database import Database
str_conn = 'oracle://<USER>:<PASS>@<HOST>:<PORT>/<INSTANCE>'
db = Database(str_conn)
command = 'INSERT INTO TABELA (COLUNA1, COLUNA2) VALUES (:valor1, :valor2)'
params = dict(valor1='ABC', valor2=123)
data = db.run(command=command, params=params)
print(data)
