Mysql字符串中有數(shù)字的排序問題?
select id,col,length(col)from D order by length(col)ASC,col ASC
或
select select id,col from D order by cast(trim(“Chinese”from col)as signed)
mysql數(shù)據(jù)庫的orderby排序無效?
order by convert(科室名稱使用)GBK)、convert(床號使用GBK)、convert(用藥時間使用GBK)列名不能用單引號括起來,這是一個字符串。UTF-8編碼格式用于根據(jù)ASCII碼、一級漢字和二級漢字對漢字進行排序
