如何从字符串SQL Server中选择第n个和第(n+1)个单词

import pyodbc

def select_words_from_sql_server(sql_server_string, n):
    # 提取SQL查询语句
    sql_query = extract_sql_query(sql_server_string)

    # 连接到SQL Server数据库
    conn = pyodbc.connect('DRIVER={SQL Server};SERVER=localhost;DATABASE=mydatabase;UID=username;PWD=password')
    cursor = conn.cursor()

    # 执行SQL查询语句
    cursor.execute(sql_query)

    # 获取查询结果
    result = cursor.fetchone()

    # 关闭数据库连接
    cursor.close()
    conn.close()

    # 将查询结果按照空格分割成单词列表
    words = result.split(' ')

    # 选择第n个和第(n+1)个单词
    selected_words = [words[n], words[n+1]]

    return selected_words

# 提取SQL查询语句的函数，具体实现略
def extract_sql_query(sql_server_string):
    # ...
    pass

# 示例用法
sql_server_string = "SELECT column1, column2 FROM table WHERE condition"
n = 2
selected_words = select_words_from_sql_server(sql_server_string, n)
print(selected_words)
