MySQL TIMESTAMPDIFF函数不返回预期结果

Question

SELECT 
    M.strMemID           AS 'Member ID', 
    M.strMemLastname         AS 'Last Name', 
    M.STRMEMFIRSTNAME         AS 'First Name', 
    M.strMemMiddlename         AS 'Middle Name', 
    TIMESTAMPDIFF(YEAR, m.dtmMemBirthday, CURRENT_DATE) AS 'Age' 
FROM TBLMEMBER M 
WHERE m.strMemID NOT IN (SELECT DISTINCT m.strmemid 
         FROM tblmember m, tblmemberministry mm, tblpositionmemberministry pmm 
         WHERE m.strMemID = mm.strMMMemID AND mm.strmemmincode = pmm.strpmmmemmincode AND (
          pmm.strPMMCode = 'POS041' OR PMM.STRPMMCODE = 'POS009' OR PMM.STRPMMCODE = 'POS010' OR 
          PMM.STRPMMCODE = 'POS012' OR PMM.STRPMMCODE = 'POS017' OR PMM.STRPMMCODE = 'POS021' OR 
          PMM.STRPMMCODE = 'POS028' OR PMM.STRPMMCODE = 'POS031' OR PMM.STRPMMCODE = 'POS037' OR 
          PMM.STRPMMCODE = 'POS039') AND mm.dtmMMDateQuit IS NULL AND pmm.dtmpmmdateto IS NULL AND 
           TIMESTAMPDIFF(YEAR, m.dtmMemBirthday, CURRENT_DATE) > 30); 

这是我的代码。请忽略令人困惑的子查询。我的目标是显示age > 30的会员。我正在使用TIMESTAMPDIFF。但是这个查询返回以及30岁以下的查询。任何人都可以帮助我吗？

我的坏人。我没有看到我的TIMESTAMPDIFF(YEAR, m.dtmMemBirthday, CURRENT_DATE) > 30在我的子查询中。现在解决了家伙！不管怎么说，多谢拉。
