Hi all, Following Dawei's suggestion, I would like to propose a new feature: regex filter. The filter enables regex matching in the where clause. This feature increases the expressiveness of IoTDB-SQL and can be useful in many use cases.
The proposed grammar is as follows SELECT ... FROM ... WHERE <*A>* MATCHES <*REGEX>* SELECT ... FROM ... WHERE <*A>* NOT MATCHES <*REGEX>* where <A>= the measurement to match. <REGEX> = the regular expression string literal. Example: select city from root.ln.wf01.wt01 where city matches ".*" Let me know if you have any suggestions of this feature and/or the grammar.
