public Class SybaseAnywhereMaxValueIncrementer

extends SybaseMaxValueIncrementer
Class Inheritance
Imports
javax.sql.DataSource

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 getGeneratedKeys method, it is recommended to use IDENTITY columns directly in the tables and then use a org.springframework.jdbc.core.simple.SimpleJdbcInsert or use a org.springframework.jdbc.support.KeyHolder when calling the update(PreparedStatementCreator psc, KeyHolder generatedKeyHolder) method of the org.springframework.jdbc.core.JdbcTemplate.

Thanks to Tarald Saxi Stormark for the suggestion!
