mysql 創建視圖

2、單表上創建視圖

CREATE VIEW V_VIEW1(ID, NAME, SEX, AGE,DEPARTMENT) AS SELECT ID, NAME, SEX, AGE,DEPARTMENT FROM learning.t_employee;

3 多表視圖

  

CREATE VIEW V_VIEW2(ID, NAME, SEX, AGE,DEPARTMENT,POS,EXPERENCE) AS SELECT a.ID, a.NAME, a.SEX, a.AGE,a.DEPARTMENT,b.POS,b.EXPERENCE FROM learning.t_employee a,learning.t_employee_detail b WHERE a.ID=b.ID;
