Alessandro is correct. But also, you can set using connect-string
parameters: lex=BIG_QUERY will, I believe, have the desired effect.

&gt; Hello,
&gt; you can achieve what you want via the SqlParser configuration
&gt; (.setQuoting() method), for instance:
&gt;
&gt;&nbsp; private static final SqlParser.Config SQL_PARSER_CONFIG =
&gt;
&gt;&nbsp;&nbsp; SqlParser.configBuilder(SqlParser.Config.DEFAULT)
&gt; &gt;&nbsp;&nbsp; .setCaseSensitive(false)
&gt; &gt;&nbsp;&nbsp; .setConformance(SqlConformanceEnum.DEFAULT)
&gt; &gt;&nbsp;&nbsp; .setQuoting(Quoting.DOUBLE_QUOTE) <----
&gt; &gt;&nbsp;&nbsp; .build();
&gt;
&gt;
&gt; Hth,

&gt; &gt; Default ??String representation is apostrophe in calcite SQL
&gt; &gt; ??like&amp;nbsp;'word'. how do I set this to Double quotes 
??like&amp;nbsp;"word".
&gt; &gt;
&gt; &gt; Default is :
&gt; &gt; select * from table1 where column1 = 'word'
&gt; &gt; I hope to support??
&gt; &gt; select * from table1 where column1 = "word"
