gengliangwang edited a comment on issue #26833: [WIP][SPARK-30203][SQL] store assignable if there is an appropriate user-defined cast function URL: https://github.com/apache/spark/pull/26833#issuecomment-564180861 @yaooqinn I think the store assignment rule is independent of the casting rule. In PostgreSQL, if you try inserting a string column to an integer column, there will be an error. It works with inserting literals though. > there shall exist an appropriate user-defined cast function UDCF from SD to TD IIUC, there is no UDCF support in Spark.
