　　自己模仿著，然後成功的完成了數據庫名的動態替換：

CREATE DEFINER=`pnggu`@`%` PROCEDURE `district_to_db`(IN city_id int ( 20 ), IN basedb_city VARCHAR ( 255 ))
BEGIN
-- 參數說明：city_id：城市id；
--                     basedb_city 需要傳遞到的業務數據庫名稱
-- REPLACE INTO basedb_sh.district ( TID, STATUS, DistrictName, DistrictFullName, DescriptionDate )
 
-- select 
-- id as TID,
-- 0 as STATUS,
-- full_name as DistrictName,
-- full_name as DistrictFullName,
-- NOW() as DescriptionDate
-- from python3.district where parent_id = ‘310100‘;

SET @sqlStmt = CONCAT(‘REPLACE INTO ‘,basedb_city,‘ .district(`TID`,`STATUS`,`DistrictName`,`DistrictFullName`,`DescriptionDate`)
        select `id` as TID,0 as STATUS,`full_name` as DistrictName,`full_name` as DistrictFullName,NOW() as DescriptionDate from python3.district where parent_id = ‘,city_id);
    PREPARE stmt FROM @sqlStmt;
    EXECUTE stmt;
END
