Python hdbcli的使用小结

from hdbcli import dbapi

# 建立连接
def connect_to_hana():
    try:
        connection = dbapi.connect(
            address='your_hana_address',
            port=30015,  # 默认连接端口号
            user='your_username',
            password='your_password'
        )
        print("Connected to SAP HANA")
        return connection
    except dbapi.Error as error:
        print(f"Connection error: {error}")
        return None

# 使用连接
connection = connect_to_hana()

# 确保在使用完连接后关闭连接
if connection:
    connection.close()

# 创建游标对象
cursor = connection.cursor()

# 执行查询
cursor.execute("SELECT * FROM YOUR_TABLE_NAME")

# 获取结果集
results = cursor.fetchall()

# 遍历结果
for row in results:
    print(row)

# 关闭游标
cursor.close()

# 插入示例
insert_query = "INSERT INTO YOUR_TABLE_NAME (column1, column2) VALUES (?, ?)"
data_to_insert = (value1, value2)

cursor.execute(insert_query, data_to_insert)

# 更新示例
update_query = "UPDATE YOUR_TABLE_NAME SET column1 = ? WHERE column2 = ?"
data_to_update = (new_value, condition_value)

cursor.execute(update_query, data_to_update)

# 提交事务以保存更改
connection.commit()
