Eric Hanson commented on HIVE-6013:
-----------------------------------
The spec sounds reasonable. I'm fine with it. I'm curious though, did you
consider allowing square brackets to delimit an identifier, like SQL Server
allows? E.g. create table sale([Shipment Date] date, ....); That seems a tad
more readable than the back-quotes.
> Supporting Quoted Identifiers in Column Names
> ---------------------------------------------
>
> Key: HIVE-6013
> URL: https://issues.apache.org/jira/browse/HIVE-6013
> Project: Hive
> Issue Type: Improvement
> Components: Query Processor
> Reporter: Harish Butani
> Assignee: Harish Butani
> Fix For: 0.13.0
>
> Attachments: HIVE-6013.1.patch, HIVE-6013.2.patch,
> QuotedIdentifier.html
>
>
> Hive's current behavior on Quoted Identifiers is different from the normal
> interpretation. 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.
