我正在尝试使用python和MySQLdb运行ETL脚本,但我坚持使用初始提取查询的结果.当我想要Int和Float时,返回的类型都是Long和Decimal.我搜索了几个小时,试图找到答案但没有任何成功.
database = MySQLdb.connect(host='db',user='user',
passwd='password', db='db123')
database_cursor = database.cursor()
database_query = ("SELECT id, siteId, campaignId, hour, sum(impressions) AS impressions, "
"sum(clicks) AS clicks, sum(conversions) AS conversions, sum(costs/1000000) AS revenue "
"FROM database.DM_PublisherFact_Hourly WHERE time = '%s' GROUP BY siteId, campaignId;") %(today)
print database_query
database_cursor.execute(database_query)
result = database_cursor.fetchone()
database.close()
返回值是Longs和Decimals的元组.我尝试将转换字典显式传递给connect对象,但没有运气.有帮助吗？
这是转换代码
