public class SybaseAnywhereMaxValueIncrementer extends SybaseMaxValueIncrementer
DataFieldMaxValueIncrementer
that increments the maximum value of a given Sybase table with the equivalent of an auto-increment column. Note: If you use this class, your table key column should NOT be defined as an IDENTITY column, as the sequence table does the job.This class is intended to be used with Sybase Anywhere.
The sequence is kept in a table. There should be one sequence table per table that needs an auto-generated key.
Example:
create table tab (id int not null primary key, text varchar(100)) create table tab_sequence (id bigint identity) insert into tab_sequence values(DEFAULT)
If "cacheSize" is set, the intermediate values are served without querying the database. If the server or your application is stopped or crashes or a transaction is rolled back, the unused values will never be served. The maximum hole size in numbering is consequently the value of cacheSize. HINT: Since Sybase Anywhere supports the JDBC 3.0getGeneratedKeys
method, it is recommended to use IDENTITY columns directly in the tables and then using aSimpleJdbcInsert
or utilizing aKeyHolder
when calling the with theupdate(PreparedStatementCreator psc, KeyHolder generatedKeyHolder)
method of theJdbcTemplate
.Thanks to Tarald Saxi Stormark for the suggestion!
