    We only recommend using the following two forms of SQL for parameter binding data insertion:
 
     ```sql
-    1. INSERT INTO meters (tbname, ts, current, voltage, phase, location, group_id) VALUES(?, ?, ?, ?, ?, ?, ?)   
-    2. INSERT INTO ? USING meters TAGS (?, ?) 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 (?, ?, ?, ?)

    我们只推荐使用下面两种形式的 SQL 进行参数绑定写入：
 
     ```sql
-    1. INSERT INTO meters (tbname, ts, current, voltage, phase, location, group_id) VALUES(?, ?, ?, ?, ?, ?, ?)

+       2. INSERT INTO ? USING meters TAGS (?, ?) VALUES (?, ?, ?, ?)
