有時候需要些插入語句需要寫字段名稱，但由於字段很多所有比較麻煩。用以下的語句就可以直接把所有字段名稱查出來直接用了
select GROUP_CONCAT(COLUMN_NAME) from information_schema.COLUMNS where table_name = 'activity_info';
合並不同數據庫中相同的表：表id 增加100（這個數字根據表自身的大小來增加）
insert into saas_award_pool_redniu_integration.activity
(Id,ActivityName,CreationTime,CreatorUserId,DeleterUserId,DeletionTime,Description,EndDateTime,HostCompany,IsActivated,IsDeleted,IsGeoRequired,IsVaild,LastModificationTime,LastModifierUserId,PublicAccountId,RuleDescription
,ServicePhoneNumber,StartDateTime,TenantId,Url)
select
Id+100,ActivityName,CreationTime,CreatorUserId,DeleterUserId,DeletionTime,Description,EndDateTime,HostCompany,IsActivated,IsDeleted,IsGeoRequired,IsVaild,LastModificationTime,LastModifierUserId,PublicAccountId,RuleDescription
,ServicePhoneNumber,StartDateTime,TenantId,Url
