time.For column names, do not use
PROCTIME or SOURCETIME. This is to avoid conflicts with system-generated timestamps.Do not start with
_DataStreamTable_.If a table or column name includes spaces or special characters, include them in backquotes, such as
HELLO WORLD.The length cannot exceed 128 half-width characters (one Chinese character or full-width character is equal to two English letters or two half-width characters).
