This isn't really a Java question, but I assume you're using JDBC. The standard SQL syntax is

select max(foo) from bar

to find the maximum value of the foo field in table bar. You'll get back a row with one element, the max value.

I belive he is reading a result set for display in, say a grid, and also needs the MAX value for one or more columns.

Is this the case?

use the following tag with the max function in sql statement

select max(foo) "mymaxfoo"
from bar


Then, use the tagname mymaxfoo in the result set accessor functions in the same way as you use column name in simple sql expressions

Infact you can use the index based accessor functions getInt(0) where 0 is the index of the first column in the result set
