strategy UUID uses the Flash UUID API to generate the ID (used for primary key of type
of type int
Applies only for INCREMENT strategy. Specifies the initial value of the primary key. The default value is 0.
initialValue
incrementBy Applies only for INCREMENT strategy. Specifies the integer with which the value must be incremented to generate the
primary key.
If the ID value is not present in the object, the value is generated and is assigned the primary key value. If the key value
is already present on the object instance, then the key generation is ignored.
For integer primary keys, the database table is checked for the presence of existing primary keys. If the highest key
value is greater than the
initialValue
value. For example, if the
initialValue
next key is generated with the value
