mysql不支持嵌套列更改

Question

    ALTER TABLE `paylist` 
  DROP PRIMARY KEY, 
  ADD PRIMARY KEY(`id`), 
  CHANGE COLUMN payment_method payment_method varchar(20) NULL AFTER supplier_id, 
  CHANGE COLUMN supplier_id supplier_id varchar(32) NULL AFTER property_number;

上述规则给出了错误：错误：'paylist'中的未知列'supplier_id'。但它们可以在separte statment中运行。例如。

 ALTER TABLE `paylist`  CHANGE COLUMN payment_method payment_method varchar(20) NULL AFTER supplier_id;

和

ALTER TABLE `paylist`  CHANGE COLUMN  supplier_id supplier_id varchar(32) NULL AFTER property_number;
