Query for the number of variable instances that fulfill given parameters. Takes the same parameters as the Get Variable Instances method.

Method

GET /variable-instance/count

Parameters

Query Parameters

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 and comma-separated process instance ids.
executionIdIn	Only include variable instances which belong to one of the passed and comma-separated execution ids.
caseInstanceIdIn	Only include variable instances which belong to one of the passed and comma-separated case instance ids.
caseExecutionIdIn	Only include variable instances which belong to one of the passed and comma-separated case execution ids.
taskIdIn	Only include variable instances which belong to one of the passed and comma-separated task ids.
batchIdIn	Only include variable instances which belong to one of the passed and comma-separated batch ids.
activityInstanceIdIn	Only include variable instances which belong to one of the passed and comma-separated activity instance ids.
tenantIdIn	Only include variable instances which belong to one of the passed and comma-separated tenant ids.
variableValues	Only include variable instances that have the certain values. Value filtering expressions are comma-separated and are structured as follows: A valid parameter value has the form key_operator_value. key is the variable name, operator is the comparison operator to be used and value the variable value. Note: Values are always treated as String objects on server side. 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. key and value may not contain underscore or comma characters.
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.
variableNamesIgnoreCase	Match all variable names provided in variableValues case-insensitively. If set to true variableName and variablename are treated as equal.
variableValuesIgnoreCase	Match all variable values provided in variableValues case-insensitively. If set to true variableValue and variablevalue are treated as equal.
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.
firstResult	Pagination of results. Specifies the index of the first result to return.
maxResults	Pagination of results. Specifies the maximum number of results to return. Will return less results if there are no more results left.

Result

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

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