Null在 spark 中将值加载到数据库时出现以下错误。Datatype目标表是smallint
Caused by: java.lang.IllegalArgumentException: Can't get JDBC type for null
代码 ：
val hivedata = spark.sql(s"""select 1 as column1 , B a column2 , NULL as column3 from table""")
hivedata .write.mode(SaveMode.Append).jdbc(url = con, table = targettable, Pconnectionropertiess)
谁能帮帮我吗
