> Due to work on https://issues.apache.org/jira/browse/FLINK-9432 I have faced with question how to check DECADE function with tests in
> _org/apache/flink/table/expressions/validation/ScalarFunctionsValidationTest.scala._ 
> Because I have used CENTURY function as an example, first of all I have check it. During the test I figured out that when we use it with TIME it returns 0.
> I suppose arguments for such functions (also it works for YEAR, MONTH, MILLENNIUM, etc) need to be checked and throw some exception if type is not suitable.
> As an example, in Apache Calcite project (checked in sqlline shell), when I am trying to use CENTURY with TIME it throw:
> {code:java}
> java.lang.AssertionError: unexpected TIME
> {code}
> Need to determine, why such check is not exists and add it.
