GeneralScalarExpression

class GeneralScalarExpression extends Expression with Serializable

The general representation of SQL scalar expressions, which contains the upper-cased expression name and all the children expressions. Please also see Predicate for the supported predicate expressions.

The currently supported SQL scalar expressions:

  • SQL semantic: expr1 * expr2
  • Since version: 3.3.0
  • Name: /
  • SQL semantic: expr1 / expr2
  • Since version: 3.3.0
  • Name: %
  • SQL semantic: expr1 % expr2
