Guojian Li updated SPARK-32638:
-------------------------------
Description:
I am migrating sql from mysql to spark sql, meet a very strange case. Below is
code to reproduce the exception:
{code:java}
val spark = SparkSession.builder()
.master("local")
.appName("Word Count")
.getOrCreate()
spark.sparkContext.setLogLevel("TRACE")
val DecimalType = DataTypes.createDecimalType(20, 2)
val schema = StructType(List(
StructField("a", DecimalType, true)
))
val dataList = new util.ArrayList[Row]()
val df=spark.createDataFrame(dataList,schema)
df.printSchema()
df.createTempView("test")
val sql=
"""
|SELECT t.kpi_04 FROM
|(
| SELECT a as `kpi_04` FROM test
| UNION ALL
| SELECT a+a as `kpi_04` FROM test
|) t
|
""".stripMargin
spark.sql(sql)
{code}
