您可以尝试下面的代码

    SELECT (@row_number:=@row_number + 1) AS num,
       TE.ID,
       TE.QUESTION,
       TE.A,
       TE.B,
       TE.C,
       TE.D,
       TE.E,
       TE.QUESTION_TYPE,
       TE.SCORE,
       S.NAME AS Subject,
       TE.CREATE_DAY,
       TE.CORRECT
     FROM TEST_TABLE TE
    INNER JOIN SUBJECT S ON S.ID = TE.SUBJECT,
   (SELECT @row_number:=0) AS t
   WHERE TE.ACTIVE =1
   AND S.ACTIVE =1 LIMIT 1,1;
