NAME
       DB::DBIncResult - An incremental query result


SYNOPSIS
       DB::DBIncResult< a >

     = DBIncRes(DB::DBHandle<a>  con,Int rows,Int cols,[String] colnames,Ptr resptr)


DESCRIPTION
       DBIncResult  holds  data  about  the  result  of  an  incremental query, if the database-specific library
       supports these.

     - rows is the number of rows in the result set.

     - cols is the number of columns in each row of the result set.

     - colnames is a list of the names of the columns

     - resptr is an internal pointer kept by the relevant database interface.

       An incremental query returns data only one row at a time, which may save memory  on  large  result  sets.
       Depending on the internal implementation in the database-specific library, the rows field may not contain
       useful information. Database-specific libraries should throw an Exception if an attempt is made  to  read
       more rows than exist.

    res = incExec(conn,"SELECT id,name FROM People");
    row = getRow(res);
    // row[0] = DBInt(id)
    // row[1] = DBText(name)
