Spark SQL - IN clause
提问by Shankar
I would like to add where condition for a column with Multiple values in DataFrame.
我想为 DataFrame 中具有多个值的列添加 where 条件。
Its working for single value, for example.
例如，它适用于单个值。
df.where($"type".==="type1" && $"status"==="completed").
How can i add multiple values for the same column like below.
我如何为同一列添加多个值，如下所示。
df.where($"type" IN ("type1","type2") && $"status" IN ("completed","inprogress")

the method you are looking for is isin:
您正在寻找的方法是isin：
import sqlContext.implicits._
df.where($"type".isin("type1","type2") and $"status".isin("completed","inprogress"))
Typically, you want to do something like this
通常，你想做这样的事情
val types = Seq("type1","type2")
val statuses = Seq("completed","inprogress")
df.where($"type".isin(types:_*) and $"status".isin(statuses:_*))
