    Description

      The error message of CREATE TEMPORARY FUNCTION IF NOT EXISTS looks confusing:

      scala> org.apache.spark.sql.SparkSession.builder().enableHiveSupport.getOrCreate.sql("CREATE TEMPORARY FUNCTION IF NOT EXISTS yuzhouwan as 'org.apache.spark.sql.hive.udf.YuZhouWan'")
      
      org.apache.spark.sql.catalyst.parser.ParseException:
      mismatched input 'NOT' expecting \{'.', 'AS'}(line 1, pos 29)
      
      == SQL ==
       CREATE TEMPORARY FUNCTION IF NOT EXISTS yuzhouwan as 'org.apache.spark.sql.hive.udf.YuZhouWan'
