 Hi there everyone,



 I can?t seem to get the below to work with PHP and MySQL:



 $sql = SELECT MAX(FoodItemNumber) FROM menuitemsubs;



 What am I doing wrong?  I need the highest number from the column
 FoodItemNumber, but it doesn?t return anything unless I change the MAX()
 to a * and I don?t want that I need it to be the MAX() number as it isn?t
 an auto-increment field.

Works a treat for me; au_linkid is a smallint which is not autoincrement, nd
not indexed at all.

mysql select max(au_linkid) from categ_link;
++
| max(au_linkid) |
++
|540 |
++
1 row in set (0.03 sec)

FoodItemNumber is an integer type?
