Description
Hi, first of all thanks for this great package.
I've used it a bit with polars and PostgreSQL and looks amazing.
I would like to use it now with Oracle but I can't really stablish a connection to my instance (DBA managed). I'd like to offer a bit more of information but I'm completely new to Rust.
When I try to connect like:
conn_str = f"oracle://{username}:{password}@{host}:{port}/{service_name}"
pl_df = cx.read_sql(conn=conn_str,
query=sql,
return_type="arrow")I get:
[2021-12-23T15:33:18Z ERROR r2d2] OCI Error: ORA-12514: TNS:listener does not currently know of service requested in connect descriptor
conn_str syntax neither works for me in SQLAlchemy since I need to establish a connection using the Service Name, not using a SID. To connect to it with SQLAlchemy:
conn_str = f"oracle://{username}:{password}@{host}:{port}/?service_name={service_name}"I think this might be somehow related.
I installed Rust and tried to explore a bit the issue but it is a lot to learn. I managed to connect to the same instance using the 2 underlying libraries connector-x uses (rust-oracle and r2d2-oracle) so I guess there might be something related to connector-x or its python interface.
use r2d2_oracle::oracle::Connection as oracle_conn;
oracle_conn::connect(username, password, "//examplehost.com:1561/servicename")I'll try to give more information, possibly in the new year but I hope this is not as extremely confusing as I feel it is :P
edit: using version 0.2.3
