An array of Columns describing the columns in the table.

o rsColumnNumbers 
 public int rsColumnNumbers[]
The numbers of the columns in the result set from which to retrieve column values.

The result set column numbers are stored in this array in ascending order. This is necessary because some databases require columns in result sets to be accessed in ascending order. Although JDBC does not appear to have this requirement, it is likely that some JDBC drivers have it anyway.
