1.GROUP_CONCAT函数:用于字段拼接比较合适,类似于foreach标签

 SELECT
    GROUP_CONCAT( NAME ORDER BY sex DESC SEPARATOR ',' ) 
FROM
    beauty

2.GROUP_CONCAT使用前和使用后对比

2.1使用前

    select distinct COLUMN_NAME  from information_schema.COLUMNS 
WHERE
column_name not in ('name') and
    table_name = 'beauty' 
    AND table_schema = 'girls';

2.2使用后:

 select group_concat(distinct COLUMN_NAME order by COLUMN_NAME ASC separator ',') from information_schema.COLUMNS 
WHERE
column_name not in ('name') and
    table_name = 'beauty' 
    AND table_schema = 'girls';
    

3.实战参考的

   begin
                                #查询该表的所有列用于拼接SQL
                                SET group_concat_max_len=102400;
                                select group_concat(distinct COLUMN_NAME order by COLUMN_NAME ASC separator ',')  into colName from `information_schema`.`COLUMNS` 
                                where TABLE_NAME  = c_a01_TblCod and COLUMN_NAME NOT IN('A00','RECORDID','T0196','T0196_01TIME') and table_schema = 'qyrlzy_avic_talent';
            end;
