public Class RowMapperNotNullConstraintsResultSetExtractor

extends RowMapperResultSetExtractor
Class Inheritance
Imports
java.sql.ResultSet, .SQLException, java.util.ArrayList, .List, .Map
Adapter implementation of the ResultSetExtractor interface that delegates to a RowMapper which is supposed to create a not null constraint object for each row.

Special mapper needed because sys table ALL_CONSTRAINTS provides info about not null constraints that have type 'C' and SEARCH_CONDITION(Text of search condition for a check constraint) field with 'is not null' string of data type: 'LONG' But type 'LONG' limits us to do any text operations (match, contains, etc.) on DB level Only one way to do this on backend side
