apache spark - How to express a column whose name contains spaces in SparkSql 1.3.1? -

-

we have tried wrapping column name brackets [column name], single & double quotes, , backticks, none of them works.

does sparksql support columns name contains spaces?

thank you!

backticks seem work fine:

scala> val df = sc.parallelize(seq(("a", 1))).todf("foo bar", "x") df: org.apache.spark.sql.dataframe = [foo bar: string, x: int] scala> df.registertemptable("df")  scala> sqlcontext.sql("""select `foo bar` df""").show foo bar

same dataframe api:

scala> df.select($"foo bar").show foo bar

so looks supported, although doubt recommended.
