Hello,

Current I am using MonetDB server v5.18.3 , and as i see in Wiki , MonetDB support hash index ,I intended to create a hash index on a table. But how to do it , i have referred to sqlmanual downloaded from monetdb.cwi.nl, but it simply wrote following format:

CREATE [UNIQUE] INDEX ON ( , ...) ; MonetDB decides itself when it needs a hash index. There is no control by the user. This SQL statement is simply a noop from the system point of view.

regards, Martin

Is that Btree index or hash index or others? Does MonetDB support multiple column hash index? I am looking forward to your reply.

Thanks a lot.
