Fetching predefinedLiteralValue(), if not set (default value) than next step, otherwise using one of predefined literals such as TRUE or CURRENT_DATE defined in LiteralValues.
Fetching signedInteger(), if not set than would be created DEFAULT constraint with value 0 (DEFAULT 0) Created by akaish on 30.04.2018.
