    Preondition Violations
    Expression log.info("Source and destination schemas were the same schema") cannot be parameterized, because it has dependencies to/from statements that will be extracted
    Expression s_log.debug("init(): expected non-null sql. Skipping execution") cannot be parameterized, because it has dependencies to/from statements that will be extracted
    Expression log.info("Source and destination schemas were the same schema") is a void method call, and thus it cannot be parameterized
