[Help]Can't get the data from Database

[eluser]iamleeloo[/eluser]
I copied and wrote some code yesterday. But the result was not satisfied.

I created 2 tables in a database named "test".
Table1: named "test" and there is 2 rows. "id" and "letters"
Data in table1: 3groups, (1,restaurant), (2,repas), (3,resto)
Table2: named "relation" and there is 3 rows. "relation_id" and "mot_1" and "mot_2"
Data in table2: 2groups, (1,restaurant,repas), (2,restaurant,resto)
