According to the [calcite official documentation](https://calcite.apache.org/docs/reference.html), the JDBC function needs to be escaped before it can be executed. We need to rewrite the SQL to the following format: ```sql SELECT order_id, {fn IFNULL(SUM(cnt), 0)} AS totoal FROM ( SELECT order_id, user_id, COUNT(1) AS cnt FROM t_order GROUP BY order_id, user_id ) a GROUP BY order_id; ``` -- This is an automated message from the Apache Git Service.
