However, this is different from ANSI SQL specification, > where double quote is used as identifier quotes. > MySQL has an option "ANSI_QUOTES", which could be switched on/off by user. > Drill should follow the same way, so that Drill users do not have to rewrite > their existing queries, if their queries use double quotes. > {code} > SET sql_mode='ANSI_QUOTES'; > {code} > -- This message was sent by Atlassian JIRA (v6.3.4#6332)
