java.lang.IllegalArgumentException: MySQL 仅支持单个生成值。 jooq r2dbc

Question

I am experiencing this issue java.lang.IllegalArgumentException: MySQL only supports single generated value. in all my insert queries not just this table. I am using jooq 3.15 and r2dbc. what could be the issue

public Mono<ResetCodesRecord> generateCode(String phone,int code) {
        return Mono.from(dsl.insertInto(RESET_CODES,RESET_CODES.PHONE, RESET_CODES.RESET_CODE)
            .values(phone,code)
            .returning()).map(record -> record.into(ResetCodesRecord.class));

    }

the generated sql seems alright to me and I have even tried inserting with it on workbench successfully

System.out.println(dsl.insertInto(RESET_CODES,RESET_CODES.PHONE, RESET_CODES.RESET_CODE) .values(phone,code).returning().getSQL());
insert into `myschema`.`reset_codes` (`phone`, `reset_code`) values (?, ?)

and the table ddl looks like this its fairly simple

CREATE TABLE `reset_codes` (
  `reset_codes_id` int(11) NOT NULL AUTO_INCREMENT,
  `reset_code` int(11) DEFAULT NULL,
  `phone` varchar(45) DEFAULT NULL,
  `created` timestamp NULL DEFAULT CURRENT_TIMESTAMP,
  PRIMARY KEY (`reset_codes_id`),
  KEY `phone_idx` (`phone`,`reset_code`)
) ENGINE=InnoDB AUTO_INCREMENT=2 DEFAULT CHARSET=utf8mb4 COLLATE=utf8mb4_0900_ai_ci;

Answer 1

So after some research I found out the exception is returned if no columns are returned in r2dbc. Issue was either insert was not happening or jooq could not return generated key. Turns out its the latter and it's a known jooq issue its documented very well here https://github.com/jOOQ/jOOQ/issues/2943 but there is a workaround for returning the generated value which is what I wanted in the first place. so below is the refactored code and its working now.

public Mono<Integer> generateCode(String phone,int code) {
        return Mono.from(dsl.insertInto(RESET_CODES).columns(RESET_CODES.PHONE, RESET_CODES.RESET_CODE)
            .values(phone,code)
            .returningResult(field("reset_codes_id", INTEGER.identity(true)))).map(record -> record.get(RESET_CODES.RESET_CODES_ID));

    }
