select distinct columns from db2 table

I'm using spring batch to read from table and write the data to another table and I'm using spring writer for the insertion part. My problem is:

I'm getting data from a table that looks like the following:

cust   type   date
====   =====  ====
 1       P    1985
 1       P    1980
 1       P    1970
 2       P    1984

and I'm trying to insert these data to another table by running a query that select distinct( cust , type) from the above table to get the following result:

cust   type   date
====   =====  ====
 1       P    1985
 2       P    1984 

so basically what I want to do is to get the distinct set of cust and type and if there are multiple records for this cust. type set then I get the max(date).

Is there anyway to do so in using query? or any recommendation for an efficient approach?

Thanks in advance!
