我试图在
PHP中运行SQL查询并按一个列排序,但按特定顺序排序
我试过这个：
$sql3="SELECT * from extension where client_id = '".$result2["id"]."' ORDER BY FIELD(type,'term','queue','ivr','voicecentre','conference','callback','intercom','queuecentre') ";
但它根本就没有订购
试试这个.希望充分利用你.

COUNT,0) ascount
from
(select ‘A’ as col union all
select ‘B’ as col union all
select ‘C’ as col union all
select ‘D’ as col )a
left join Table1 T
on a.col=T.type
order by FIELD(a.col,’A’,’B’,’C’,’D’) ;
