Workflow.Worker

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

See also: Workflow.Worker.Parameter, Workflow.Worker.ResultField

Basic usage

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

Data fields

By default, Workflow.Worker 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.Worker' and FieldType = 'Column';

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

Examples

Note: For more example Luminesce SQL queries, visit our Github repo.

Example 1: Retrieve first 10 workers

select * from Workflow.Worker limit 10;

Example 2: Retrieve information on a particular worker

select * from Workflow.Worker where Scope = 'Finbourne-Examples' and Code = 'UpsertPortfolio';

Example 3: Retrieve all workers that use a particular Luminesce view

select * from Workflow.Worker where WorkerConfiguration like '%Worker.UpsertTransactionPortfolio%';
