mysql 複製表以及表結構

 

1.複製表結構及資料到新表
    create table新表select * from舊錶  
2.只複製表結構到新表
方法1 :(低版本的mysql不支援,mysql4.0.25不支援,mysql5已經支援了)
    建立表新表如舊錶  
方法2:
    建立表新表select * from舊錶limit 0 
方法3:
    create table新表select * from舊錶其中不成立條件
3.複製舊錶的資料到新表
1,(假設兩個表結構一樣)
    插入新表select * from舊錶  
2,(假設兩個表結構不一樣)
    insert into新表(欄位1,欄位2,......)選擇欄位1,欄位2,......來自舊錶
如
INSERT INTO zbasecourse(zbasecourse.id,
zbasecourse.username,
zbasecourse.userId,
zbasecourse.studyCount,
zbasecourse.secondMajorTittle,
zbasecourse.secondMajorId,
zbasecourse.salesStatus,
zbasecourse.`code`,
zbasecourse.cover,
zbasecourse.`name`,
zbasecourse.isCompetitiveProducts,
zbasecourse.displayName,
zbasecourse.dateCreate,
zbasecourse.majortittle,
zbasecourse.majorId
) SELECT zbase_course.id,
zbase_course.username,
zbase_course.user_id,
zbase_course.study_count,
zbase_course.second_major_tittle,
zbase_course.second_major_id,
zbase_course.sales_status,
zbase_course.`code`,
zbase_course.cover,
zbase_course.`name`,
zbase_course.is_competitive_products,
zbase_course.display_name,
zbase_course.date_create,
zbase_course.majortittle,
zbase_course.major_id from zbase_course
