Sorting Order in SQL Queries

Hi Colleagues,

We notice difference in the output when executing the SELECT queries on traditional DB and HANA. We are using side car approach so we have both the databases.

    SELECT Query 1 without HANA

     SELECT * FROM

                     EKPO

          INTO   TABLE LT_EKPO

             FOR ALL ENTRIES IN LT_EKKO

    WHERE    ebeln = lt_ekko-ebeln

          AND   werks IN s_werks.

    SELECT Query 2 with HANA

     SELECT * FROM

                     EKPO

          connection (gv_dbcon)

          INTO   TABLE LT_EKPO

             FOR ALL ENTRIES IN LT_EKKO

    WHERE    ebeln = lt_ekko-ebeln

          AND   werks IN s_werks.

Both the queries give me the same result set, but with different order.

What could be the reason? and how this should be avoided.

Thank you.

Harshad Mishrikotkar.
