我运行 SELECT * FROM company WHERE company.apply_id = 1 和 SELECT * FROM apply WHERE apply.apply_id = 1 都没有问题，但是为什么运行 SELECT DISTINCT apply.client_name AS 客户姓名, apply.client_id AS 客户 ID, company.company_name AS 公司名称, company.company_province_name AS 公司省, company.company_city_name AS 公司市, company.company_county_name AS 公司县区, company.company_other AS 公司其他, company.department AS 部门, company.office_level_name AS 职位, company.salary AS 月薪, company.other_income AS 其他收入, company.industry_name AS 行业, company.nature AS 单位性质, company.company_size AS 公司规模 FROM apply INNER JOIN company.apply_id = apply.apply_id 的时候，就提示 [Err] 1064 - You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near '.apply_id' at line 18
