argument with
Field.getName()
"MY_field"
(case-sensitive!), a
corresponding field with the same name in this record will be searched.Field.getName()
, then the first one returning true on
Field.equals(Object)
will be returned. (e.g. qualified field
names match)
Table.getRecordType()
must return a class of type
TableRecord
, which must provide a default constructor. Non-public
default constructors are made accessible using
AccessibleObject.setAccessible(boolean)
public final ResultSet intoResultSet()
Record
ResultSet
containing the data of this
Record
.
Use this as an adapter for JDBC-compliant code that expects a
ResultSet
to operate on, rather than a jOOQ Result
. The
returned ResultSet
allows for the following behaviour
according to the JDBC specification:
ResultSet.CLOSE_CURSORS_AT_COMMIT
: The cursors (i.e.
Statement
object) are no longer availableResultSet.CONCUR_READ_ONLY
: You cannot update the database
through this ResultSet
, as the underlying Result
object does not hold any open database refences anymoreResultSet.FETCH_FORWARD
: The fetch direction is forward only,
and cannot be changedResultSet.TYPE_SCROLL_INSENSITIVE
: You can use any of the
ResultSet
's scrolling methods, e.g. ResultSet.next()
or ResultSet.previous()
, etc.
You may use DSLContext.fetch(ResultSet)
to unwind this wrapper
again.
This is the same as creating a new Result
with this
Record
only, and then calling Result.intoResultSet()
on that Result

in interface Record

public final <E> E map(RecordMapper<Record,E> mapper)
Record
public final void from(Object source)
Record
The mapping algorithm is this:
source
is an array
Loading of data is delegated to Record.fromArray(Object...)
source
is a Map
Loading of data is delegated to Record.fromMap(Map)
Column
annotations are found on the Class
of the provided source
, only those are used. Matching
candidates are:
Column
getXXX
or isXXX
, if there exists a matching public single-argument
setXXX()
instance method that is annotated with
Column
Column
Column.name()
must match Field.getName()
. All other
annotation attributes are ignored
Column
annotations, or jOOQ can't
find the javax.persistence
API on the classpath, jOOQ will
map members by naming convention:
If Field.getName()
is MY_field
(case-sensitive!),
then this field's value will be fetched from the first of these:
MY_field()
myField()
getMY_field()
getMyField()
MY_field
myField
The resulting record will have its internal "changed" flags set to true
for all values. This means that UpdatableRecord.store()
will
perform an INSERT
statement. If you wish to store the record
using an UPDATE
statement, use
DSLContext.executeUpdate(UpdatableRecord)
instead.

public int compareTo(Record that)
Record
Record
with another Record
according to their natural ordering.
jOOQ Records implement Comparable
to allow for naturally ordering
Records in a "SQL way", i.e. according to the following rules:
Two Records are comparable if and only if they have the same
ROW
type, i.e. if their fieldsRow()
methods return fields of the same type and degree.
Assume the following notations:
X[i]
means X.getValue(i)
X = Y
means X.compareTo(Y) == 0
X < Y
means X.compareTo(Y) < 0
X[i] = Y[i]
means
(X[i] == null && Y[i] == null) || X[i].compareTo(Y[i]) < 0
X[i] < Y[i]
means
Y[i] == null || X[i].compareTo(Y[i]) < 0
. This
corresponds to the SQL NULLS LAST
clause.r1
and r2
,
x = r1.compareTo(r2)
yields:
x = -1
: if
(r1[0] < r2[0])
OR (r1[0] = r2[0] AND r1[1] < r2[1])
OR ...
OR (r1[0] = r2[0] AND ... AND r1[N-1] = r2[N-1] AND r1[N] < r2[N])
x = 0
: if
OR (r1[0] = r2[0] AND ... AND r1[N-1] = r2[N-1] AND r1[N] = r2[N])
x = 1
: if
(r1[0] > r2[0])
OR (r1[0] = r2[0] AND r1[1] > r2[1])
OR ...
OR (r1[0] = r2[0] AND ... AND r1[N-1] = r2[N-1] AND r1[N] > r2[N])
Note, that the above rules correspond to the SQL ordering behaviour as
illustrated in the following examples:
-- A SQL ORDER BY clause, ordering all records by columns in their order
SELECT a, b, c
FROM my_table
ORDER BY 1, 2, 3
-- A row value expression comparison predicate
SELECT *
FROM my_table
WHERE (a, b, c) < (1, 2, 3)
See Row1.lessThan(Row1)
, Row2.lessThan(Row2)
, ...,
Row22.lessThan(Row22)
for more details about row value expression
comparison predicates
Alternative sorting behaviour can be achieved through
Result.sortAsc(java.util.Comparator)
and similar methods.
