private static final SqlParser.Config SQL_PARSER_CONFIG = SqlParser.configBuilder(SqlParser.Config.DEFAULT) > .setCaseSensitive(false) > .setConformance(SqlConformanceEnum.DEFAULT) > .setQuoting(Quoting.DOUBLE_QUOTE) <---- > .build(); Hth, Alessandro On Wed, 16 Dec 2020 at 09:55, 莫失莫忘 <xiaoxiong....@qq.com> wrote: > Default ,String representation is apostrophe in calcite SQL > ,like 'word'. how do I set this to Double quotes ,like "word". > > Default is : > select * from table1 where column1 = 'word' > I hope to support: > select * from table1 where column1 = "word"
