The Ultimate Guide to High Availability with MariaDB

Object Name : Naming Rule ?

Hello. I have some questions regarding to MariaDB ColumnStore object naming rules. I'm a bit puzzled when I came up to issue a CREATE TABLE statement...

I have read the following page, but my question is not mentioned ; - https://mariadb.com/kb/en/mariadb/columnstore-naming-conventions/

1) For non-ASCII characters (but in UTF-8 defined) , such as Japanese or special controll character CR/LF , can it be used in object names (tables and columns for example) ? (Assuming to quote it surrounding by ` )

2) Seems like including hyphen in column name caused an error upon CREATE TABLE statement. Such as a column named `col-1` `col-2` ; - ERROR 328856920 - The storage engine for the table doesn't support The syntax or the data type(s) is not supported by Columnstore. Is this an expected behavior ? Any other characters that are not allowed ?

3) Confirmed that the statement works on both normal (I mean non ColumnStore) MariaDB and MySQL but fails on MariaDB ColumnStore mode.

Thank you in advance.

Currently, you should limit yourself to alphanumeric and underscore only, i.e. "A-Z a-z 0-9 _". I have corrected https://mariadb.com/kb/en/mariadb/columnstore-naming-conventions/ and filed an enhancement for this:https://jira.mariadb.org/browse/MCOL-716
