我想查出 开始日期(event_start_time)或 结束日期(event_end_time)在 2015-11的所有数据
这个 where 语句要怎么写?

.... where data_format(event_start_time, '%Y-%m') = '2015-11' or data_format(event_end_time, '%Y-%m') = '2015-11'

.... where data_format(event_start_time, '%Y-%m') = '2015-11' or data_format(event_end_time, '%Y-%m') = '2015-11'



data_format does not exist
