+# SHOW CONFIG
+
+> **警告：**
+>
+> 当前该功能为实验特性，不建议在生产环境中使用。
+
+`SHOW CONFIG` 语句用于展示 TiDB 各个组件当前正在应用的配置，请注意，配置与系统变量作用于不同维度，请不要混淆，如果希望获取系统变量信息，请使用 [SHOW VARIABLES](/sql-statements/sql-statement-show-variables.md) 语法。

+显示所有配置：
+
+{{< copyable "sql" >}}
+
+```sql
+SHOW CONFIG;
+```

+
+显示 `type` 是 `tidb` 的配置：
+
+{{< copyable "sql" >}}
+
+```sql
+SHOW CONFIG WHERE type = 'tidb' AND name = 'advertise-address';
+```
+
+```

++------+----------------+-------------------+-----------+
+1 row in set (0.05 sec)

+
+也可以用 `LIKE` 子句来显示 `type` 是 `tidb` 的配置：
