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.
