If the time interval between two continuous rows are within the time interval specified by `tol_val` they belong to the same session window; otherwise a new session window is started automatically. +`EVENT_WINDOW` is determined according to the window start condition and the window close condition. The window is started when `start_trigger_condition` is evaluated to true, the window is closed when `end_trigger_condition` is evaluated to true. `start_trigger_condition` and `end_trigger_condition` can be any conditional expressions supported by TDengine and can include multiple columns. + +`COUNT_WINDOW` is a counting window that is divided by a fixed number of data rows.`count_val`: A constant, which is a positive integer and must be greater than or equal to 2. The maximum value is 2147483648. `count_val` represents the maximum number of data rows contained in each `COUNT_WINDOW`. When the total number of data rows cannot be divided by `count_val`, the number of rows in the last window will be less than `count_val`. `sliding_val`: is a constant that represents the number of window slides, similar to `SLIDING` in `INTERVAL`. + For example, the following SQL statement creates a stream and automatically creates a supertable named `avg_vol`.
