MySQL : error in your SQL syntax | LIMIT 0, 25

Question

我不明白这个错误，请大家帮帮我。为什么我收到这个错误..我的查询有问题吗？

这是错误..

#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 'LIMIT 0, 25' at line 7

这是我的查询:

SELECT
    equivalent
FROM
    tb_student_record
INNER JOIN
    tb_student ON tb_student_record.stud_id = tb_student.stud_id 
WHERE
    tb_student_record.instructor_id = 'INST-20131296' 
    AND tb_student_record.criteria_id = '1' 
    AND tb_student_record.class_record_id = '1' 
    AND (CONCAT(stud_fname, ' ', stud_lname) = 'Jeffrey Oliveras' 
    AND tb_student_record.term = 'Prelim'

Answer 1

您在 concat 函数中缺少结束括号

SELECT equivalent FROM tb_student_record INNER JOIN tb_student ON tb_student_record.stud_id=tb_student.stud_id 
WHERE tb_student_record.instructor_id = 'INST-20131296' 
AND tb_student_record.criteria_id = '1' 
AND tb_student_record.class_record_id = '1' 
AND (CONCAT(stud_fname, ' ', stud_lname) = 'Jeffrey Oliveras' )
AND tb_student_record.term = 'Prelim'
