如何用多个搜索条件编写MYSQL CASE WHEN语句？

Question

我知道像PHP这样的语言有一个switch case控制结构,支持在单个case语句中进行多次验证,比如

Switch $x {
  case 1,2,3: 
      $a = 0;
       break;
  case 5,6: 
       $a = 1;
       break;
}

同样可以在MYSQL中完成吗？我试过下面,虽然真的没有用:(

CASE vc_shape
   WHEN ('02' OR '51') THEN SET dc_square_1 = dc_square_1 + dc_row_total;
   WHEN ('06' OR  '30' OR 83) THEN SET dc_square_2 = dc_square_2 + dc_row_total; 
   .....
   .....
  ELSE
      BEGIN
      END;
END CASE; 

任何想法我怎样才能做到这一点？

Answer 1

使用其他格式的CASE语句:

CASE 
   WHEN vc_shape IN ('02', '51') THEN SET dc_square_1 = dc_square_1 + dc_row_total;
   WHEN vc_shape IN ('06', '30', '83') THEN SET dc_square_2 = dc_square_2 + dc_row_total; 
   .....
   .....
  ELSE
      BEGIN
      END;
END CASE;
