我的查询字符串如下:

SELECT ... FROM maintable
LEFT JOIN table1 on (maintable.id = table1.idx)
LEFT JOIN table2 on (table1.idy = table2.idy)
LEFT JOIN table3 on (table2.idz = table3.idz)
WHERE (condition1 OR condition2 OR condition3)
AND maintable.status = static

//condition1 & condition2 & condition3 are kind of
table3.idz = 101, table3.idz = 3, maintable.id IN (1,2,3,4), and so on

对于结果,我希望condition1首先返回满足的条目,然后是满足的condition2条目,最后是满足的条目condition3.有任何想法吗？
