dm-pure：纯 Python 达梦 DM8 数据库驱动
零 native 依赖、100% Python 实现的达梦 DM8 数据库驱动，适合无编译环境的机器。
源码版 wheel（py3-none-any），任何 Python 3.8+ 通用。
功能
参数化查询（含 NULL）/ 中文（自动检测服务器编码）/ 大结果集分批 fetch / CLOB·BLOB / 事务 / 存储过程 / 批量插入 executemany / 连接池 / DB-API 2.0 兼容层。
安装
pip install dm-pure
零依赖：加密（DES/AES/RC4）内置纯 Python 实现；若安装 pycryptodome 会自动优先使用（性能更优）。
快速上手
from dmpy import DMClient
c = DMClient("127.0.0.1", 5236, "SYSDBA", "password") # 自动检测服务器字符集
c.connect()
c.execute("SELECT id, name FROM t WHERE id = ?", [1]) # → (cols, rows)
c.execute("INSERT INTO t VALUES (?, ?)", [1, "x"]) # → (None, 影响行数)
c.close()
DB-API 2.0（sqlite3/pymysql 风格）
import dmpy.dbapi as dm
conn = dm.connect(host="127.0.0.1", port=5236, user="SYSDBA", password="...")
cur = conn.cursor()
cur.execute("SELECT id, name FROM t WHERE id >= ?", [1])
print(cur.fetchall())
conn.close()
SQLAlchemy 集成：请使用 dmPython-pure（shim 兼容层）， 它内置 SQLAlchemy 方言
sqlalchemy.dialects:dm，可直接create_engine("dm://...")。 本包（dm-pure）保持纯核心驱动，不捆绑 API 适配层。
环境要求
- Python >= 3.8
- 可达的达梦 DM8 服务器（TCP 5236 端口）
