Usage

import pydbc_oracle  # registers OracleDriver with DriverManager
from pydbc_core import DriverManager

conn = DriverManager.get_connection(
    "pydbc:oracle://system:password@localhost:1521/FREEPDB1"
)
stmt = conn.create_statement()
rs = stmt.execute_query("SELECT 1 FROM dual")
print(rs.rows)
conn.close()

Parameterised queries

# Positional parameters (translated to :1, :2 numerics)
ps = conn.prepare_statement("SELECT * FROM users WHERE id = ?")
ps.set_int(1, 42)
rs = ps.execute_query()

# Named parameters (translated to :1, :2 numerics)
ps = conn.prepare_statement("SELECT * FROM users WHERE id = :id")
ps.set_int(1, 42)
rs = ps.execute_query()

Paramstyle note

python-oracledb uses named paramstyle internally (:name placeholders), but pydbc forces numeric (:1, :2) for this driver because the ParamstyleNormalizer handles both ? and :name inputs and produces numeric output that oracledb accepts.
