| title: LOAD STATS | ||

| category: reference | ||

|
||
| # LOAD STATS | ||
|
|
||
| `LOAD STATS` 语句用于将统计信息加载到 TiDB 中。 | ||
|
|
||
| ## 语法图 | ||
|
|
||
| **LoadStatsStmt:** | ||
|
|
||
|  | ||
|
|
||
| ## 参数说明 | ||
|
|
||
| 用户直接指定统计信息文件路径,统计信息文件可通过访问 API `http://${tidb-server-ip}:${tidb-server-status-port}/stats/dump/${db_name}/${table_name}` 进行下载。 | ||
|
|
||
| 路径可以是相对路径,也可以是绝对路径,如果是相对路径,会从启动 `tidb-server` 的路径为起点寻找对应文件。 | ||
|
|
||
| 下面是一个绝对路径的例子: | ||
|
|
||
| {{< copyable "sql" >}} | ||
|
|
||
| ```sql | ||
| LOAD STATS '/tmp/stats.json'; | ||
| ``` | ||
|
|
||
| ``` | ||
| Query OK, 0 rows affected (0.00 sec) | ||
| ``` | ||
|
