Question

I have two tables

table1

+-------+-------+
| NAME  | PRICE |
+-------+-------+
| ITEM1 |  100  |
+-------+-------+
| ITEM2 |  200  |
+-------+-------+
| ITEM3 |  300  |
+-------+-------+

table2 repeats ITEM1 and ITEM2

    +-------+--------+---------+
    | NAME  | SUFFIX | CODE    |
    +-------+--------+---------+
    | ITEM1 | 1      | ITEM1_1 |
    +-------+--------+---------+
    | ITEM1 | 2      | ITEM1_2 |
    +-------+--------+---------+
    | ITEM2 | 1      | ITEM2_1 |
    +-------+--------+---------+

How can I do this result whit mySQL?

+-------+-------+----------+
| NAME  | PRICE |   NAME2  |
+-------+-------+----------+
| ITEM1 |  100  |  ITEM1   |
+-------+-------+----------+
| ITEM2 |  200  |  ITEM2   |
+-------+-------+----------+
| ITEM3 |  300  |  NULL    |
+-------+-------+----------+

I want to get elements from table1 which is not in table2. In this case the element I want to get is ITEM3. Can I do this with LEFT JOIN?

Answer 1

Select * from table1 s Left join table2 as t on s.NAME=t.NAME where t.NAME IS NULL
