Question

I have two tables:

table1:

---------------------------
|id_column1 | name_column |
---------------------------
|        1  | my_name1    |
|        2  | my_name2    |
---------------------------

table2:

--------------------------------------
|id_column2 | surname_column | fk_id1|
--------------------------------------
|      111  | my_surname1    | 1     |
|      222  | my_surname2    | 2     |
--------------------------------------
fk_id1 is foreign key referenced to table1.id_column1

SELECT * FROM table1 WHERE fk_id1=1;

--------------------------------------
|id_column2 | surname_column | fk_id1|
--------------------------------------
|      111  | my_surname1    | 1     |

How can I get this (is it possible at all to join two table columns as result):

------------------------------------------------
|id_column2 | surname_column | fk_id1| name    |
------------------------------------------------
|      111  | my_surname1    | 1     |my_name1 |

Something like below:

SELECT * FROM table2 WHERE fk_id1=1 AND SELECT name FROM table1 WHERE id_column1=1;

Answer 1

You mean something like this ?

SELECT t2.*, t1.name_column 
FROM table2 t2 
     INNER JOIN table1 t1 on t2.fk_id1 = id_column1 
WHERE t1.id_column1 = 1

Here’s a sample SQL Fiddle for testing.
