问题:
文档(<a href="https://ci.apache.org/projects/flink/flink-docs-release-1.10/dev/table/sql/queries.html#scan-projection-and-filter)使用'%'求余运算,在SQL解析报错:">https://ci.apache.org/projects/flink/flink-docs-release-1.10/dev/table/sql/queries.html#scan-projection-and-filter)使用'%'求余运算,在SQL解析报错: org.apache.calcite.sql.parser.SqlParseException: Percent remainder '%' is not allowed under the current SQL conformance level
MYSQL conformance 支持'%'运算,使用MYSQL CONFORMANCE,在SQL语法校验过程会找不到'%'对应的SqlOperator
