这种sql语句怎么写

想把表A中的数据排序，取出前X个，插入到表B中，同时插入另外两个参数

DROP PROCEDURE IF EXISTS SetValue;
CREATE PROCEDURE SetValue(
IN paramA INT,
IN paramB INT,
IN paramC INT,
IN paramD INT)
BEGIN

  SET @result = 0;  
  
  SET @prepareStatement = CONCAT("SELECT RoleName, Score FROM A WHERE attr=", paramA ," ORDER BY Score DESC limit ", paramB );
 INSERT INTO B values (paramC ,paramD ,上面select的结果) ;
  PREPARE stmt FROM @prepareStatement;
  EXECUTE stmt;
  DEALLOCATE PREPARE stmt;
END

SET @prepareStatement = CONCAT(" INSERT INTO B ","SELECT ",paramC,",",paramC,",","RoleName, Score FROM A WHERE attr=", paramA ," ORDER BY Score DESC limit ", paramB );
 ;
