     IF(namea<>'')THEN
        SET @selectSql =CONCAT(@selectSql,' where name like ',"'%",namea,"%'");
     END IF;

     IF(b<>'')THEN
        SET @selectSql =CONCAT(@selectSql,' and type in ',"(",b ,")");
     END IF;


     SET @selectSql =CONCAT(@selectSql,' order by id desc');
    -- SELECT @selectSql; -- 打印sql语句

    PREPARE stmt FROM @selectSql;
    EXECUTE stmt ;
    DEALLOCATE PREPARE stmt;
end;


call my_pro('zhang','"123","12"');
