Get Variable Instances Count (POST)

Query for the number of variable instances that fulfill given parameters. This method takes the same message body as the POST query and therefore it is slightly more powerful than the GET query count.

Method

POST /variable-instance/count

Parameters

Request Body

A JSON object with the following properties:

Name Description
variableName Filter by variable instance name.
variableNameLike Filter by the variable instance name. The parameter can include the wildcard % to express like-strategy such as: starts with (%name), ends with (name%) or contains (%name%).
processInstanceIdIn Only include variable instances which belong to one of the passed process instance ids.
executionIdIn Only include variable instances which belong to one of the passed execution ids.
caseInstanceIdIn Only include variable instances which belong to one of the passed case instance ids.
caseExecutionIdIn Only include variable instances which belong to one of the passed case execution ids.
taskIdIn Only include variable instances which belong to one of the passed task ids.
activityInstanceIdIn Only include variable instances which belong to one of the passed activity instance ids.
tenantIdIn Only include variable instances which belong to one of the passed and comma-separated tenant ids.
variableValues A JSON array to only include variable instances that have the certain values.
The array consists of objects with the three properties name, operator and value. name (String) is the variable name, operator (String) is the comparison operator to be used and value the variable value.
value may be String, Number or Boolean.
Valid operator values are: eq - equal to; neq - not equal to; gt - greater than; gteq - greater than or equal to; lt - lower than; lteq - lower than or equal to; like.
sortBy Sort the results lexicographically by a given criterion. Valid values are variableName, variableType, activityInstanceId and tenantId. Must be used in conjunction with the sortOrder parameter.
sortOrder Sort the results in a given order. Values may be asc for ascending order or desc for descending order. Must be used in conjunction with the sortBy parameter.

Result

A JSON object that contains the count as the only property.

Name Value Description
count Number The number of matching variable instances.

Response Codes

Code Media type Description
200 application/json Request successful.
400 application/json Returned if some of the query parameters are invalid, for example if a sortOrder parameter is supplied, but no sortBy, or if an invalid operator for variable comparison is used. See the Introduction for the error response format.
