我试图排除所有毛列都为空值的行。
示例数据:
market item_id gross_1 gross_2 gross_3 period
POLAND 1111 1 2 3 20190301
ESTONIA 2222 blank 2 3 20190302
POLAND 3333 1 blank 3 20190303
POLAND 3333 1 blank blank 20190304
POLAND 4444 blank blank blank 20190305
POLAND 5555 1 2 3 20190306`
我想收到:
market item_id gross_1 gross_2 gross_3 period
POLAND 1111 1 2 3 20190301
ESTONIA 2222 blank 2 3 20190302
POLAND 3333 1 blank 3 20190303
POLAND 3333 1 blank blank 20190304
POLAND 5555 1 2 3 20190306`
我发现了类似的东西，但它在 snowflake 中不起作用:
WHERE NOT ROW(gross_1, gross_2, gross_3) IS NULL
最佳答案
使用coalesce() :
select * from tablename
where coalesce(gross_1, gross_2, gross_3) is not null
关于sql - 根据多列排除行，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/58028650/
