Hi all,
I tried our SQL parser on version 1.32.0 and 1.36.0.
I used double quote(") as literal quote string in my sql expression, and set it
on my parser config, but it threw a sql parse exception:
org.apache.calcite.sql.parser.impl.ParseException: Encountered "\"" at line 1,
column 26.
Was expecting one of:
"ABS" ...
"ARRAY" ...
"AVG" ...
I am not sure if this is bug, because double quote for literal string is not a
rare case.
Here is the my test case:
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();
}
Wish to get your reply.
Thanks,
Peng
