我在雪花中有一张桌子,结构如下,
----------------------------------------
Name | Number
----------------------------------------
Dim_1 | {'Table_1': 100}
Dim_1 | {'Table_1': 101}
Dim_2 | {'Table_2': 200, 'Table_3': 300}
Dim_2 | {'Table_2': 201, 'Table_3': 301}
我试图得到输出:
-----------------------
Name | Table | Entries
-----------------------
Dim_1 | Table_1 | 100
Dim_1 | Table_1 | 101
Dim_2 | Table_2 | 200
Dim_2 | Table_3 | 300
Dim_2 | Table_2 | 201
Dim_2 | Table_3 | 301
有任何想法吗?
