使用临时列名而不是索引从 MySQL/Python 查询中检索数据

Question

如何使用列名从 MySQL 查询中检索数据（我只是按索引使用它）。例如，这是我的示例代码：

query = ('SELECT Column1 as name, Column2 as lastname, Column 3 as othername FROM '
         'table WHERE condition = 1 ORDER BY name ASC LIMIT 1')
cursor.execute(query) # I'll get just 1 result
results = cursor.fetchall()

if not results:
  connection.close()
  ..
else:
  for row in results:
    var = row[0] # <- Here is the problem, I am using the index to retrieve 
                 # the result from query, I wanna to use 'var = row["name"]' instead
                 # but this throw me an error because row must be integer type
    ...

我希望你能帮助我。谢谢，祝你有个愉快的一天。

嘿，为了使用 'row["name"]'，您需要制作一个查询字典。这可以通过使用 dictcursor 来完成...

光标 = connection.cursor(pymysql.cursors.DictCursor) cursor.execute(查询)
