mysql - 还有其他的sql子句吗？

Question

SELECT 
    tbl_tmpdtr.id, 
    tbl_tmpdtr.userid, 
    date(tbl_tmpdtr.in_out) as in_out, 
    tbl_tmpdtr.status, 
    tbl_employee.emp_id, 
    tbl_employee.emp_lname, 
    tbl_employee.emp_mname, 
    tbl_employee.emp_fname 
FROM tbl_tmpdtr 
INNER JOIN tbl_employee 
    ON tbl_tmpdtr.userid = tbl_employee.emp_id 
WHERE 
    tbl_tmpdtr.in_out >= '2015-05-01' 
    AND tbl_tmpdtr.in_out <= '2015-05-05'
GROUP BY
    tbl_tmpdtr.userid

在上面的 SQL 查询中，我想使用特定的 id 进行查询。但是我已经使用了 WHERE 子句。我怎样才能正确地做到这一点？或者你们有什么想法吗？或者有什么方法？

如果我理解正确，这将帮助您:

SELECT 
    tbl_tmpdtr.id, 
    tbl_tmpdtr.userid, 
    date(tbl_tmpdtr.in_out) as in_out, 
    tbl_tmpdtr.status, 
    tbl_employee.emp_id, 
    tbl_employee.emp_lname, 
    tbl_employee.emp_mname, 
    tbl_employee.emp_fname 
FROM tbl_tmpdtr 
INNER JOIN tbl_employee 
    ON tbl_tmpdtr.userid = tbl_employee.emp_id 
WHERE 
    tbl_tmpdtr.in_out >= '2015-05-01' 
    AND tbl_tmpdtr.in_out <= '2015-05-05' and tbl_tmpdtr.id=(specific id)
GROUP BY
    tbl_tmpdtr.userid
