peng wu updated CALCITE-6142:
-----------------------------
    Description: 
When tried to parse spark sql express where double quote(") as literal quote 
string, calcite sql parser threw an exception: 
    org.apache.calcite.sql.parser.impl.ParseException: Encountered "\"" at line 
1, column 26.
    Was expecting one of:
    "ABS" ...
    "ARRAY" ...    "AVG" ...
The literal quote string is specified in sql parser config.

Here is my test case:
{code:java}
public static void main(String[] args) throws Exception {
    String sqlQuery = "case  when `Area` in (   \"Region1\", \"Region2\", 
\"Region3\"  ) then `Sales`  else null end";
    //create spark dialect
    SqlDialect.Context context = SqlDialect.EMPTY_CONTEXT
            .withDatabaseProduct(SqlDialect.DatabaseProduct.SPARK)
            .withUnquotedCasing(Casing.UNCHANGED)
            .withNullCollation(NullCollation.LOW)
            .withIdentifierQuoteString("`")
            .withLiteralQuoteString("\"");
    SqlDialect sparkDialect = new SparkSqlDialect(context);
    SqlParser.Config config = sparkDialect.configureParser(SqlParser.config());
    // Create an SQL parser
    SqlParser parser = SqlParser.create(sqlQuery, config);
    // Parse the query into an AST. Here the exception occurred
    SqlNode sqlNode = parser.parseExpression();
  } {code}
