I am using spark-csv to load data into a DataFrame. I want to do a simple query and display the content:

val df = sqlContext.read.format("com.databricks.spark.csv").option("header", "true").load("my.csv")
df.registerTempTable("tasks")
results = sqlContext.sql("select col from tasks");
results.show()

 

The col seems truncated:

scala> results.show();
+--------------------+
|                 col|
+--------------------+

+--------------------+

How do I show the full content of the column?

To prevent your result from truncating, add this to your code:

results.show(False) 

or 

results.show(false)
