# Workflow.Worker

| **Type** | **Read/write** | **Author** | **Availability** |
| --- | --- | --- | --- |
| [Data provider](/v1/docs/what-are-a-data-provider-and-a-direct-provider) | Read | FINBOURNE | Provided with LUSID |

Providing you have sufficient [access control permissions](/v1/docs/creating-policies-to-control-access-to-providers-for-different-luminesce-end-users), the `Workflow.Worker` provider enables you to write a [Luminesce SQL query](/v1/docs/understanding-the-luminesce-sql-query-syntax) that retrieves [workers](/v1/docs/how-do-i-create-a-worker) from the Workflow Service.

**See also**: [Workflow.Worker.Parameter](/v1/docs/workflowworkerparameter), [Workflow.Worker.ResultField](/v1/docs/workflowworkerresultfield)

## Basic usage

```sql
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](/v1/docs/what-tools-are-available-to-write-luminesce-queries):

```sql
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](https://github.com/finbourne/luminesce-examples/tree/master/examples).

### Example 1: Retrieve first 10 workers

```sql
select * from Workflow.Worker limit 10;
```

### Example 2: Retrieve information on a particular worker

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

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

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