Question

Is it possible in MySQL to create tables that use other column from another table dynamically (same idea as extending a class in PHP). Example:

table1
    table1_id
    column1
    column2
    column3

table2
    table2_id
    column4
    column5

So when I query table2 I get all the columns from table1 like:

SELECT table1_id,column1,column2,column3,table2_id,column4,column5 FROM table2;

Answer 1

CREATE VIEW t2_view AS <SELECT stuff FROM t1,t2> (not sure exactly how you want to join t1 and t2)

SELECT * FROM t2_view;

Something like that is what you are looking for I think.
