Thanks Cetin!

>>Hi all, I have a table with the following fields: Family, name, age and level. In this table a family can have several members and I need a SQL statement that gets me the older member of each family order by level. For example:
>>
>>
>>Family  Name      Age    Level
>>--------------------------------
>>01      xxxxxxxx   15      1
>>01      xxxxxxxx   13      1
>>01      xxxxxxxx   17      2
>>02      xxxxxxxx   12      1
>>02      xxxxxxxx   15      1
>>02      xxxxxxxx   13      1
>>03      xxxxxxxx   13      1
>>03      xxxxxxxx   18      2
>>03      xxxxxxxx   12      1
>>
>>
>>
>>The result should be:
>>
>>
>>Family  Name      Age    Level
>>--------------------------------
>>01      xxxxxxxx   15      1
>>02      xxxxxxxx   15      1
>>03      xxxxxxxx   13      1
>>01      xxxxxxxx   17      2
>>03      xxxxxxxx   18      2
>>
>>
>>
>>Any help is greatly appreciated!

I'm a mixture of Albert Einstein and Arnold Schwarzenegger. The only trouble is that I got Einstein's body and Schwarzenegger's brain
