Question

Lets say I have two tables

table_1

ID  Name   Status
1   John   
2   Peter  
3   Smith  

table_2

ID  UID   Status  UpdateDate
1   1     B       2010-05-05
2   1     C       2011-03-02
3   3     C       2011-03-02
4   2     A       2011-03-02

What is the correct statement to update Status on table_1 according to UpdateDate on table_2.

Result should be like this

table_1

ID  Name   Status
1   John   C
2   Peter  A
3   Smith  C

Thanks.

Answer 1

UPDATE table_1 SET Status = (
    SELECT Status FROM table_2
    WHERE UID = table_1.ID
    ORDER BY UpdateDate desc
    LIMIT 1
    );
