 **Tips: It is recommended to use parameter binding for data insertion**
 
+   :::note
+   We only recommend using the following two forms of SQL for parameter binding data insertion:
+
+    ```sql
+    a. Subtables already exists:
+       1. INSERT INTO meters (tbname, ts, current, voltage, phase) VALUES(?, ?, ?, ?, ?) 
+    b. Automatic table creation on insert:
+       1. INSERT INTO meters (tbname, ts, current, voltage, phase, location, group_id) VALUES(?, ?, ?, ?, ?, ?, ?)   
+       2. INSERT INTO ? USING meters TAGS (?, ?) VALUES (?, ?, ?, ?)
+    ```
+
+   :::
+
 Next, we continue to use smart meters as an example to demonstrate the efficient writing functionality of parameter binding with various language connectors:
 
 1. Prepare a parameterized SQL insert statement for inserting data into the supertable `meters`. This statement allows dynamically specifying subtable names, tags, and column values.

 **Tips: 数据写入推荐使用参数绑定方式**
 
+   :::note
+   我们只推荐使用下面两种形式的 SQL 进行参数绑定写入：
+
+    ```sql
+    一、确定子表存在：
+       1. INSERT INTO meters (tbname, ts, current, voltage, phase) VALUES(?, ?, ?, ?, ?)  
+    二、自动建表：
+       1. INSERT INTO meters (tbname, ts, current, voltage, phase, location, group_id) VALUES(?, ?, ?, ?, ?, ?, ?)   
+       2. INSERT INTO ? USING meters TAGS (?, ?) VALUES (?, ?, ?, ?)
+    ```
+
+   :::
+
 下面我们继续以智能电表为例，展示各语言连接器使用参数绑定高效写入的功能：
 1. 准备一个参数化的 SQL 插入语句，用于向超级表 `meters` 中插入数据。这个语句允许动态地指定子表名、标签和列值。
 2. 循环生成多个子表及其对应的数据行。对于每个子表：
