Workflow.TaskDefinition

Providing you have sufficient access control permissions, the Workflow.TaskDefinition provider enables you to write a Luminesce SQL query that retrieves task definitions from the Workflow Service.

See also: Workflow.TaskDefinition.Action, Workflow.TaskDefinition.Schema, Workflow.TaskDefinition.Transition 

Basic usage

select * from Workflow.TaskDefinition where <filter-expression>

Data fields

By default, Workflow.TaskDefinition returns a table of data populated with particular fields (columns). You can return a subset of these fields.

To list fields available to return, their data types, whether fields are considered 'main', and an explanation for each, run the following query using a suitable tool:

select FieldName, DataType, IsMain, IsPrimaryKey, SampleValues, Description from Sys.Field where TableName = 'Workflow.TaskDefinition' and FieldType = 'Column';

Note: Fields marked 'main' are returned by queries that select a caret character, for example select ^ from Workflow.TaskDefinition.

Examples

Example 2: Retrieve task definitions created by a particular user

select * from Workflow.TaskDefinition where CreatedBy = '00ujiW7gSOp024j7Fg98';

Example 3: Retrieve states for a particular task definition

select States from Workflow.TaskDefinition where Scope = 'approvals' and Code = 'dataApproval';
