> `default`.`customer_source` `src`
> ON `src`.`id` = `trg`.`id`
> INSERT INTO `default`.`customer_target` -- update clause
> select `trg`.`id`, `src`.`first_name`, `src`.`last_name`, `trg`.`age`
> WHERE `src`.`id` = `trg`.`id`
> sort by `trg`.id
> INSERT INTO `default`.`customer_target` -- insert clause
> select `src`.`id`, `src`.`first_name`, `src`.`last_name`, `src`.`age`
> WHERE `trg`.`id` IS NULL
> {code}
> *ACTUAL RESULT*
> {code}
> FAILED: SemanticException [Error 10087]: The same output cannot be present multiple times: customer_target
