# timeSeriesSamples

`timeSeriesSamples(db_name.time_series_table)` - 返回表引擎为 [TimeSeries](/zh/reference/engines/table-engines/integrations/time-series) 的表 `db_name.time_series_table` 所使用的[样本表](/zh/reference/engines/table-engines/integrations/time-series#samples-table)：

```sql theme={null}
CREATE TABLE db_name.time_series_table ENGINE=TimeSeries SAMPLES samples_table
```

如果内部表是 *samples* 表，该函数同样适用：

```sql theme={null}
CREATE TABLE db_name.time_series_table ENGINE=TimeSeries SAMPLES INNER UUID '01234567-89ab-cdef-0123-456789abcdef'
```

以下查询是等效的：

```sql theme={null}
SELECT * FROM timeSeriesSamples(db_name.time_series_table);
SELECT * FROM timeSeriesSamples('db_name.time_series_table');
SELECT * FROM timeSeriesSamples('db_name', 'time_series_table');
```

<Note>
  函数 `timeSeriesSamples` 有一个别名 `timeSeriesData`，保留该别名是为了向后兼容。
