Class DbSqlSession.BulkDeleteOperation

java.lang.Object

org.activiti.engine.impl.db.DbSqlSession.BulkDeleteOperation

All Implemented Interfaces:

DbSqlSession.DeleteOperation

Enclosing class:

DbSqlSession

public class DbSqlSession.BulkDeleteOperation
extends Object
implements DbSqlSession.DeleteOperation

Use this DbSqlSession.DeleteOperation to execute a dedicated delete statement. It is important to note there won't be any optimistic locking checks done for these kind of delete operations!

For example, a usage of this operation would be to delete all variables for a certain execution, when that certain execution is removed. The optimistic locking happens on the execution, but the variables can be removed by a simple 'delete from var_table where execution_id is xxx'. It could very well be there are no variables, which would also work with this query, but not with the regular DbSqlSession.CheckedDeleteOperation.
