自己模仿着，然后成功的完成了数据库名的动态替换：
CREATE DEFINER=`pnggu`@`%` PROCEDURE `district_to_db`(IN city_id int ( 20 ), IN basedb_city VARCHAR ( 255 )) BEGIN -- 参数说明：city_id：城市id； -- basedb_city 需要传递到的业务数据库名称 -- 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
