> Currently the "replace" function requires to be enclosed within backticks (ie. `replace`); otherwise it would fail during the parsing.
> For example the following query fails:
> 0: jdbc:drill:schema=M7> select replace(substring(name,1,10), 'or', 'EA') from `dfs.default`.voter where name like 'victor%';
> Query failed: Failure while parsing sql. Encountered "replace" at line 1, column 8.
> Was expecting one of:
>     "UNION" ...
>     "INTERSECT" ...
>     "EXCEPT" ...
> .
> .
> .
> The following modified query succeeds:
> 0: jdbc:drill:schema=M7> select `replace`(substring(name,1,10), 'or', 'EA') from `dfs.default`.voter where name like 'victor%';
> +------------+
> |   EXPR$0   |
> +------------+
> | victEA tho |
> | victEA you |
> | victEA rob |
> | victEA van |
> | victEA rob |

> The parse error was originally filed in this jira: https://issues.apache.org/jira/browse/DRILL-738.  We should find a way to avoid requiring backticks as this is a standard sql function.
