Do you really want to do a cartesian product on those two tables?
If yes, you can set
pache.spark.sql.Dataset.showString(Dataset.scala:254)
at org.apache.spark.sql.Dataset.show(Dataset.scala:723)
at org.apache.spark.sql.Dataset.show(Dataset.scala:682)
at org.apache.spark.sql.Dataset.show(Dataset.scala:691)
The table A and B don't have same column.
What can I do please?

Hi ，
I checked the code.
It seems it is hard to change the code.
Current code, string + int is translated to double + double.
If I change the the string + int to string + sting, it will incompatible whit
old version.
Does anyone have better idea about this issue please?

Hi,
Using concat is one of the way.
But the + is more intuitive and easy to understand.

Hi,

(eval1, eval2) => s"(${ctx.javaType(dataType)})($eval1 $symbol $eval2)")
case CalendarIntervalType =>
defineCodeGen(ctx, ev, (eval1, eval2) => s"$eval1.add($eval2)")
case _ =>
defineCodeGen(ctx, ev, (eval1, eval2) => s"$eval1 $symbol $e
