# Lusid.TransactionType.SideDefinition

| **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.TransactionType.SideDefinition` provider enables you to write a [Luminesce SQL query](/v1/docs/understanding-the-luminesce-sql-query-syntax) that retrieves [sides](/v1/docs/what-is-a-side) from a particular transaction type scope.

Note that Luminesce knows nothing about your [custom transaction type scopes](/v1/docs/grouping-related-transaction-types-using-scopes-and-sources). If you omit the `Scope` parameter, LUSID retrieves sides from the built-in `default` scope. You cannot retrieve sides from *all* scopes.

**See also:** [Lusid.TransactionType](/v1/docs/lusidtransactiontype)

## Basic usage

```sql
select * from Lusid.TransactionType.SideDefinition where <filter-expression>
```

## Query parameters

`Lusid.TransactionType.SideDefinition` 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.TransactionType.SideDefinition' and FieldType = 'Parameter';
```

## Data fields

By default, `Lusid.TransactionType.SideDefinition` 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.TransactionType.SideDefinition' and FieldType = 'Column';
```

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

## Examples

### Example 1: Retrieve the first ten sides from the default scope

If you omit the `Scope` parameter, only the built-in `default` scope is searched.

```sql
select * from Lusid.TransactionType.SideDefinition limit 10
```

### Example 2: Retrieve all sides where the amount derives from a property

```sql
select * from Lusid.TransactionType.SideDefinition where Amount like 'Transaction/%'
```
