Quoted Identifier (using backticks) has a special > interpretation for Select expressions(as Regular Expressions). Have > documented current behavior and proposed a solution in attached doc. > Summary of solution is: > - Introduce 'standard' quoted identifiers for columns only. > - At the langauage level this is turned on by a flag. > - At the metadata level we relax the constraint on column names. -- This message was sent by Atlassian JIRA (v6.1.4#6159)
