# Lusid.PostingModule.Rule

| **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 `Lusid.PostingModule.Rule` provider enables you to write a [Luminesce SQL query](/v1/docs/understanding-the-luminesce-sql-query-syntax) that retrieves [posting rules](/v1/docs/assigning-economic-activity-to-general-ledger-accounts-using-posting-rules) for one or more posting modules.

`Lusid.PostingModule.Rule` returns one record per posting rule. The `RulePriority` field reports the order of the posting rule in the set belonging to a particular posting module; lower numbers take precedence and are evaluated earlier.

**See also**: [Lusid.PostingModule.Rule.Writer](/v1/docs/lusidpostingmodulerulewriter)

## Basic usage

```sql
select * from Lusid.PostingModule.Rule where <filter-expression>;
```

## Query parameters

`Lusid.PostingModule.Rule` has parameters that enable you to filter or refine a query.

To list available parameters, their data types, default values, 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, ParamDefaultValue, Description from Sys.Field where TableName = 'Lusid.PostingModule.Rule' and FieldType = 'Parameter';
```

## Data fields

By default, `Lusid.PostingModule.Rule` 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 = 'Lusid.PostingModule.Rule' and FieldType = 'Column';
```

> **Note:** Fields marked 'main' are returned by queries that select a caret character, for example `select ^ from Lusid.PostingModule.Rule`.
