| PlatformPostgreSQLImpl | | public class PlatformPostgreSQLImpl extends PlatformDefaultImpl (Code) | | This class extends PlatformDefaultImpl and defines specific
behavior for the PostgreSQL platform.
Many of the database sequence specific properties can be specified using
custom attributes within the sequence-manager element.
The database sequence specific properties are generally speaking, see database user guide
for detailed description.
Implementation configuration properties:
| Property Key |
Property Values |
| sequenceStart |
DEPRECATED. Database sequence specific property.
Specifies the first sequence number to be
generated. Allowed: 1 or greater.
|
| seq.start |
Database sequence specific property.
Specifies the first sequence number to be
generated. Allowed: 1 or greater.
|
| seq.incrementBy |
Database sequence specific property.
Specifies the interval between sequence numbers.
This value can be any positive or negative
integer, but it cannot be 0.
|
| seq.maxValue |
Database sequence specific property.
Set max value for sequence numbers.
|
| seq.minValue |
Database sequence specific property.
Set min value for sequence numbers.
|
| seq.cycle |
Database sequence specific property.
If true, specifies that the sequence continues to generate
values after reaching either its maximum or minimum value.
If false, specifies that the sequence cannot generate more values after
reaching its maximum or minimum value.
|
| seq.cache |
Database sequence specific property.
Specifies how many values of the sequence Oracle
preallocates and keeps in memory for faster access.
Allowed values: 2 or greater. If set 0,
an explicite nocache expression will be set.
|
| seq.order |
Database sequence specific property.
If set true, guarantees that sequence numbers
are generated in order of request.
If false, a no order expression will be set.
