如何在MySQL中将默认值从一个表插入到另一个表

Question

I have 3 tables, one named employees , one Documents , and one Doctemplates

employees and documents have relationship, and doctemplates contain several document names.

What I need is when i add a new employee , under documents, system add the defaults documents templates form table doctemplates , so i don't have to type one by one.

Is there any way to do this, in a mysql query or php?

Answer 1

INSERT INTO documents (employeeId, col1, col2, col3)
SELECT $employeeId, c1, c2, c3 FROM doctemplates;

You can do it manually or from trigger.

WHAT YOU WANT IS TO INSERT DATA FROM DOCTEMPLETS TO DOCUMENTS.FOR THIS YOU HAVE TO CREATE A RELATION BETWEEN EMPLOYEE AND DOCTEMPLETS,THEN DEFINE A FOREIGN KEY IN DOCUMENTS TABLE FROM DOCTEMPLETS. IF YOU WANT MORE ABOUT FOREIGN KEY DEFINING.PLZ ASK NEXT. THANS
