Dan Cojocaru updated CALCITE-4080:
----------------------------------
Description:
Exception occurs while parsing query with quoted alias for select columns.
{code:java}
final FrameworkConfig config = Frameworks.newConfigBuilder()
.parserConfig(SqlParser.configBuilder().setLex(Lex.MYSQL)
.setConformance(SqlConformanceEnum.MYSQL_5).build())
.programs(Programs.ofRules(Programs.RULE_SET))
.build();
Planner p = Frameworks.getPlanner(config);
SqlNode n = p.parse("SELECT 1 AS 'some alias' from dual");
{code}
The following exception is thrown:
{code:java}
org.apache.calcite.sql.parser.SqlParseException: Encountered "\'some alias\'"
at line 1, column 13.
Was expecting one of:
<BRACKET_QUOTED_IDENTIFIER> ...
<QUOTED_IDENTIFIER> ...
<BACK_QUOTED_IDENTIFIER> ...
<IDENTIFIER> ...
<UNICODE_QUOTED_IDENTIFIER> ...{code}
If query is changed into :
{code:java}
"SELECT 1 AS some_alias from dual"
{code}
the query is parsed correctly.
Quoted aliases ( e.g: 'some alias' ) {color:#172b4d}should be valid as
well.{color}
