Wang Yanlin updated CALCITE-3281:
---------------------------------
Description:
Currently, the value of [expression0 and expression1
|https://github.com/apache/calcite/blob/master/linq4j/src/main/java/org/apache/calcite/linq4j/tree/BinaryExpression.java#L26]
must be the same type.
Otherwise, when evaluate, we will get a ClassCastException, something like this
{code:java}
java.lang.ClassCastException: java.lang.Integer cannot be cast to java.lang.Long
