Examples

Example #1

テーブル <code>({[ key = "x", a = 1, b = null, c = 3 ], [ key = "y", a = 2, b = 4, c = null ]})</code> の列 "a"、"b"、および "c" を受け取り、属性/値のペアにピボット解除します。

Table.Unpivot(
    Table.FromRecords({
        [key = "x", a = 1, b = null, c = 3],
        [key = "y", a = 2, b = 4, c = null]
    }),
    {"a", "b", "c"},
    "attribute",
    "value"
)

Result:

Table.FromRecords({
    [key = "x", attribute = "a", value = 1],
    [key = "x", attribute = "c", value = 3],
    [key = "y", attribute = "a", value = 2],
    [key = "y", attribute = "b", value = 4]
})
