# LegacyAdaptableQuery

Pre-v25 expression wrapper as it appears in persisted state. Until v24 a
`Rule` / `Query` was an object whose single key named the expression kind
(`Expression` / `AggregatedExpression` / `ObservableExpression`, plus the
pre-v24 spellings). From v25 the property is the expression string itself
and the kind is inferred from the text; `CalculatedColumn.Query` and
`Report.Query` are renamed to `Expression`.

```ts title="TypeScript"
export interface LegacyAdaptableQuery 
```

## Properties

| Property | Type | Description |
| --- | --- | --- |
| [AggregatedExpression](https://www.adaptabletools.com/docs/reference/legacyadaptablequery.md#aggregatedexpression) | `string` | Aggregated expression text (a brace call). Current state stores the string directly; the kind is inferred. |
| [Expression](https://www.adaptabletools.com/docs/reference/legacyadaptablequery.md#expression) | `string` | Per-row expression text. Current state stores this string directly on `Rule` or `Expression`. |
| [ObservableExpression](https://www.adaptabletools.com/docs/reference/legacyadaptablequery.md#observableexpression) | `string` | Observable expression text. Current state stores the string directly and treats it as a scalar expression. |
