timeSeriesMetrics(db_name.time_series_table) - 返回表引擎为 TimeSeries 的表 db_name.time_series_table 所使用的指标表：

CREATE TABLE db_name.time_series_table ENGINE=TimeSeries METRICS metrics_table

当 metrics 表为内表时，该函数同样适用：

CREATE TABLE db_name.time_series_table ENGINE=TimeSeries METRICS INNER UUID '01234567-89ab-cdef-0123-456789abcdef'

以下查询是等价的：

SELECT * FROM timeSeriesMetrics(db_name.time_series_table);
SELECT * FROM timeSeriesMetrics('db_name.time_series_table');
SELECT * FROM timeSeriesMetrics('db_name', 'time_series_table');
