A table or column name uniquely identifies a table or column. Stream Compute Service has the following rules regarding the naming of tables and columns:
Do not use fields reserved for data types. If you have to, include them in backquotes, for example, 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).
