disableBinaryFetching

public HistoricDetailQuery disableBinaryFetching()

Description copied from interface: HistoricDetailQuery

Disable fetching of byte array and file values. By default, the query will fetch such values. By calling this method you can prevent the values of (potentially large) blob data chunks to be fetched. The variables themselves are nonetheless included in the query result.

Returns:

the query builder

orderPartiallyByOccurrence

public HistoricDetailQuery orderPartiallyByOccurrence()

Description copied from interface: HistoricDetailQuery

Sort the historic detail events in the order in which they occurred and needs to be followed by Query.asc() or Query.desc().

The set of all historic variable update events is a partially ordered set. Due to this fact historic variable update events for two different variable instances are incomparable. So that it is not possible to sort the historic variable update events for two variable instances in the order they occurred. Just for one variable instance the set of historic variable update events can be totally ordered by using HistoricDetailQuery.variableInstanceId(String) and HistoricDetailQuery.orderPartiallyByOccurrence() which will return a result set ordered by its occurrence.

For example:
An execution variable myVariable will be updated multiple times:

runtimeService.setVariable("anExecutionId", "myVariable", 1000);
execution.setVariable("myVariable", 5000);
runtimeService.setVariable("anExecutionId", "myVariable", 2500);
runtimeService.removeVariable("anExecutionId", "myVariable");

As a result there exists four historic variable update events.

By using HistoricDetailQuery.variableInstanceId(String) and HistoricDetailQuery.orderPartiallyByOccurrence() it is possible to sort the events in the order in which they occurred. The following query

historyService.createHistoricDetailQuery()
.variableInstanceId("myVariableInstId")
.orderPartiallyByOccurrence()
.asc()
.list()

will return the following totally ordered result set

[
HistoricVariableUpdate[id: "myVariableInstId", variableName: "myVariable", value: 1000],
HistoricVariableUpdate[id: "myVariableInstId", variableName: "myVariable", value: 5000],
HistoricVariableUpdate[id: "myVariableInstId", variableName: "myVariable", value: 2500]
HistoricVariableUpdate[id: "myVariableInstId", variableName: "myVariable", value: null]
]

Note:
Please note that a historic form field event can occur only once.
