如何对每个SQL的数据集进行反序列化?
示例源表:
UserID | Name | Email1 | Email2 | Email3
-----------------------------------------------------
1 MaxMan max.man@example1.com max.man@example2.com
2 MaxGirl max.girl@example2.com
示例Out Table:
ID | Name | Email
-----------------------------
1 MaxMan max.man@example1.com
2 MaxMan max.man@example2.com
3 MaxGirl max.girl@exmaple2.com
谢谢!
