大家好，
我在MySQL数据库中有以下表格。
id report_date value event_id event_start_date event_end_date
1 5/31/1978 10
1 6/30/1978 20
1 7/31/1978 30
1 8/31/1978 40
1 9/30/1978 70
1 10/31/1978 90
1 11/30/1978 10 a 11/25/1978 11/29/1978
1 12/31/1978 30
1 1/31/1979 50
2 7/31/2012 28
2 8/31/2012 40
2 9/30/2012 60
2 10/31/2012 100 b 10/2/2012 10/4/2012
2 11/30/2012 120
2 12/31/2012 130
2 1/31/2013 140
我想在事件开始日期和事件结束日期之间为该ID添加行，其值为零，这些日期将作为报告日期。所以结果表应该是这样的：
id report_date value event_id event_start_date event_end_date
1 5/31/1978 10
1 6/30/1978 20
1 7/31/1978 30
1 8/31/1978 40
1 9/30/1978 70
1 10/31/1978 90
1 11/30/1978 10 a 11/25/1978 11/29/1978
1 11/25/1978 0 a 11/25/1978 11/29/1978
1 11/26/1978 0 a 11/25/1978 11/29/1978
1 11/27/1978 0 a 11/25/1978 11/29/1978
1 11/28/1978 0 a 11/25/1978 11/29/1978
1 11/29/1978 0 a 11/25/1978 11/29/1978
1 12/31/1978 30
1 1/31/1979 50
2 7/31/2012 28
2 8/31/2012 40
2 9/30/2012 60
2 10/31/2012 100 b 10/2/2012 10/4/2012
2 10/2/2012 0 b 10/2/2012 10/4/2012
2 10/3/2012 0 b 10/2/2012 10/4/2012
2 10/4/2012 0 b 10/2/2012 10/4/2012
2 11/30/2012 120
2 12/31/2012 130
2 1/31/2013 140
我无法找到办法。有人请帮我解决这个问题。 感谢
