[jira] [Created] (SPARK-17764) to_json function for parsing Structs to json Strings

Hyukjin Kwon created SPARK-17764:
------------------------------------

             Summary: to_json function for parsing Structs to json Strings
                 Key: SPARK-17764
                 URL: https://issues.apache.org/jira/browse/SPARK-17764
             Project: Spark
          Issue Type: Improvement
          Components: SQL
            Reporter: Hyukjin Kwon


After SPARK-17699, now Spark supprots {{from_json}}. It might be nicer if we have {{to_json}} too, in particular, in the case to write out dataframes by some data sources not supporting nested structured types.
