Cannot resolve column (numeric column name) in Spark Dataframe

Question

This is my data:

scala> data.printSchema
root
 |-- 1.0: string (nullable = true)
 |-- 2.0: string (nullable = true)
 |-- 3.0: string (nullable = true)
         


        

Answer 1

You can use backticks to escape the dot, which is reserved for accessing columns for struct type:

data.select("`2.0`").show
+---+
|2.0|
+---+
| , |
+---+
