/**
* A database result record.
*
* A record essentially combines a list of columns ({@link Field}) with a
* corresponding list of values, each value being of the respective field's
* type.
*
* While records can be seen as generic column / value mappings, their concrete
* implementations often specialise the above description in any of the
* following ways:
*
*
Table records
*
* Records originating from a concrete database table (or view) are modelled by
* jOOQ as {@link TableRecord} or {@link UpdatableRecord}, if they contain a
* primary key. If you're using jOOQ's code generator, you can generate even
* more concrete types of table records, i.e. one table record per table.
*
*
UDT records
*
* {@link SQLDialect#ORACLE} and {@link SQLDialect#POSTGRES} formally support
* user defined types (UDT), which are modelled by jOOQ as {@link UDTRecord}. In
* addition to being regular records (column / value mappings), they also
* implement the JDBC {@link SQLData} API in order to be streamed to a JDBC
* {@link PreparedStatement} or from a JDBC {@link ResultSet}
*
*
Records of well-defined degree
*
* When projecting custom record types in SQL, new ad-hoc types of a certain
* degree are formed on the fly. Records with degree <= 22 are reflected by
* jOOQ through the {@link Record1}, {@link Record2}, ... {@link Record22}
* classes, which cover the respective row value expressions {@link Row1},
* {@link Row2}, ... {@link Row22}
*
* Note that generated TableRecords and UDTRecords
* also implement a Record[N] interface, if N <= 22
*
*
Record implements Comparable
*
* jOOQ records have a natural ordering implemented in the same way as this is
* defined in the SQL standard. For more details, see the
* {@link #compareTo(Record)} method
*
* @author Lukas Eder
