Oracle

SELECT COL_A, COL_B
  FROM (SELECT COL_A,

               row_number() over (order by COL_A) rn
          FROM XPTO.MY_TABLE )

WHERE rn BETWEEN {{ TOLONG(SUM(SUBTRACT(MULTIPLY(message.page, message.pageSize), message.pageSize), 1)) }}


AND {{ TOLONG(MULTIPLY(message.page, message.pageSize)) }}
