现在我正在使用查询获取数据，但出现错误。请帮帮我。 我的查询是 SELECT * FROM testdata.orders where line_items.vfsku = 'VFPQ123_VT1'

Answer 1

查看如何scan for STRUCT field values that satisfy a condition:

SELECT *
FROM testdata.orders
WHERE EXISTS(SELECT 1 FROM UNNEST(line_items) WHERE vfsku = 'VFPQ123_VT1');

Answer 2

试试这个

SELECT *
FROM testdata.orders,UNNEST(line_items)
WHERE vfsku = 'VFPQ123_VT1';
