Description

SQL:1992 supports delimited identifiers for schema objects in queries:

(http://www.contrib.andrew.cmu.edu/~shadow/sql/sql1992.txt, §5.2, p82)

<delimited identifier> ::= <double quote> <delimited identifier body> <double quote>

Currently Impala only allows backticks around shema objects, which can cause issues for some versions of some tools which produce queries of the form:

select * from "table";
