there is table id, name; 
 table tweak B, and there are fields time, id, name; 
. Now I want to insert all the databases of table tweak An into the database of tweeb. 
 originally thought 
 `insert into tweeb (id, name) 
 select id, name from tat _ A` 
but I found that I could not initialize the time field of tweak B. what should I do if I also set a current time for the time field when I want to insert tweeb?
