Description
使用withJion连表查询,希望主表某个字段不要查询,再使用withoutField,会报错,因为withoutField设置的field没有表名。
不使用withoutField时:
SELECT
`system_admin`.`id`,
`system_admin`.`auth_id`,
`system_admin`.`head_img`,
`system_admin`.`username`,
`system_admin`.`password`,
`system_admin`.`phone`,
`system_admin`.`remark`,
`system_admin`.`login_num`,
`system_admin`.`sort`,
`system_admin`.`status`,
`system_admin`.`create_time`,
`system_admin`.`update_time`,
`system_admin`.`delete_time`,
`system_admin`.`nickname`,
`system_admin`.`email`,
`system_admin`.`wechat_official_account_openid`,
`system_admin`.`notifications_setting`,
`system_admin`.`uid`,
`systemAuth`.`id` AS `systemAuth__id`,
`systemAuth`.`title` AS `systemAuth__title`
FROM
`ea_system_admin` `system_admin`
LEFT JOIN `ea_system_auth` `systemAuth` ON `system_admin`.`auth_id` = `systemAuth`.`id`
WHERE
`system_admin`.`delete_time` IS NULL
ORDER BY
`system_admin`.`sort` DESC,
`system_admin`.`id` DESC
LIMIT
0, 15
使用时,除了正确的字段,后面还多了一批字段:
SELECT
`system_admin`.`id`,
`system_admin`.`auth_id`,
`system_admin`.`head_img`,
`system_admin`.`username`,
`system_admin`.`password`,
`system_admin`.`phone`,
`system_admin`.`remark`,
`system_admin`.`login_num`,
`system_admin`.`sort`,
`system_admin`.`status`,
`system_admin`.`create_time`,
`system_admin`.`update_time`,
`system_admin`.`delete_time`,
`system_admin`.`nickname`,
`system_admin`.`email`,
`system_admin`.`wechat_official_account_openid`,
`system_admin`.`notifications_setting`,
`system_admin`.`uid`,
`systemAuth`.`id` AS `systemAuth__id`,
`systemAuth`.`title` AS `systemAuth__title`,
`id`,
`auth_id`,
`head_img`,
`username`,
`password`,
`phone`,
`remark`,
`login_num`,
`sort`,
`status`,
`create_time`,
`update_time`,
`delete_time`,
`nickname`,
`email`,
`wechat_official_account_openid`,
`notifications_setting`,
`uid`
FROM
`ea_system_admin` `system_admin`
LEFT JOIN `ea_system_auth` `systemAuth` ON `system_admin`.`auth_id` = `systemAuth`.`id`
WHERE
`system_admin`.`delete_time` IS NULL
ORDER BY
`system_admin`.`sort` DESC,
`system_admin`.`id` DESC
LIMIT
0, 15
会导致报错:
SQLSTATE[23000]: Integrity constraint violation: 1052 Column 'id' in field list is ambiguous
无论在withoutField中怎样的写法都不行:
->withoutField('system_admin.password')
->withoutField('password')

Research direction
Reproduce the reported query using withJoin and withoutField, comparing the two generated SELECT statements shown in the issue. Trace how both options build the selected field list; done means excluding the requested main-table field without adding duplicate unqualified columns, so the joined query executes without the ambiguous-column error.
