Describe the bug
Unable to compare DATETIME and TIMESTAMP for logical operators and CASE.

Or for query issues:'

1. Run the query 'SELECT TIMESTAMP(DATE("2010-04-12")) = SUBDATE(TIMESTAMP(DATE("2010-04-12")), INTERVAL 1 HOUR)'
2. See error "ExpressionEvaluationException"

Expected behavior
The SQL plugin should be able to compare DATETIME and TIMESTAMP or SUBDATE and ADDDATE should have output of type TIMESTAMP.
