云原生数据湖分析 DLA - 文档停止维护：MSCK REPAIR TABLE语法

同步OSS数据源上实际的数据分区信息到元数据中

语法

MSCK REPAIR TABLE table_name

示例

在命令执行前，SHOW PARTITIONS primitives_parquet_p无法显示分区信息。

mysql> show partitions primitives_parquet_p;
+--------+
| Result |
+--------+
|        |
+--------+
1 row in set (0.85 sec)

执行完MSCK REPAIR TABLE命令后，可以看到对应的分区信息：

mysql> msck repair table primitives_parquet_p;
+--------+
| Result |
+--------+
| NULL   |
+--------+
1 row in set (0.94 sec)
mysql> show partitions primitives_parquet_p;
+--------------------------------------------------------------------------+
| Result                                                                   |
+--------------------------------------------------------------------------+
| year=2009/month=1
year=2009/month=2
year=2009/month=3
year=2009/month=4
 |
+--------------------------------------------------------------------------+
1 row in set (0.33 sec)
