Ruben Q L commented on CALCITE-5123:
------------------------------------
Correct, quoted identifiers do support starting with a digit (among other
advantages, e.g. being able to use a SQL reserved word as identifier).
Would this be a viable solution in your case? If so, shall we consider closing
the current ticket?

> Not sure if this is related solely to Spark:
>
> Parsing the following query errors in Calcite:
> {code:java}
> public static void main(String[] args) throws SqlParseException {
> String sqlQuery = "SELECT a AS 1a FROM FakeTable";
> SqlParser.create(sqlQuery,
> SparkSqlDialect.DEFAULT.configureParser(SqlParser.config())).parseQuery();
> } {code}
> {noformat}
> Exception in thread "main" org.apache.calcite.sql.parser.SqlParseException:
> Encountered "1" at line 1, column 13.
> {noformat}
> However, Spark does accept such queries:
