php - 如何修复 SQL 查询中的错误

Question

错误 SQL 查询:文档

SELECT * 
FROM tbl_vehicle_details 
INNER JOIN tbl_user, tbl_ride 
ON `tbl_vehicle_details`.`v_u_id` = `tbl_user`.`u_id` AND 
   `tbl_ride`.`r_v_id` =`tbl_vehicle_details`.`v_id` 
LIMIT 0, 25

MySQL said: Documentation

#1064 - You have an error in your SQL syntax; check the manual that corresponds to your MariaDB server version for the right syntax to use near 'ON tbl_vehicle_details.v_u_id = tbl_user.u_id AND tbl_ride.r_v_id = ' at line 1

Answer 1

您将隐式连接语法与显式连接语法混合在一起。试试这个:

SELECT * 
FROM tbl_vehicle_details 
INNER JOIN tbl_user
ON `tbl_vehicle_details`.`v_u_id` = `tbl_user`.`u_id`
INNER JOIN tbl_ride 
ON `tbl_ride`.`r_v_id` =`tbl_vehicle_details`.`v_id` 
LIMIT 0, 25

注意:在没有 ORDER BY 子句的情况下使用 LIMIT 会导致任意选择记录，因为 SQL 中没有固有顺序表。
