Database View is not appearing in the ABAP Coding

Question

Dear Friends,
I am very much new in the ABAP. Actually I worked last 8 years in the Oracle PL/SQL. Recently, my company implements SAP. The database is Oracle 10g. I would like to use my oracle experience in the project. But in everywhere I faced some problem.
I have created one Database view by the Native sql. Here I am giving you the code.
Create OR REPLACE view ZVMVSL_ALLTPORT
AS
SELECT T1.MVESSEL_NO, T1.MVESSEL_NAME, T1.SHIPPINGLINE, T2.MVOYAGENUMBER,
T2.TRANSHIPMENTA AS TPORT, T2.ETDTSHIPMENTA AS ETD_TPORT,
T3.MVESSEL_SRL_NO,
T3.PORTOFDISCHARGE POD, T3.ETAPORT
FROM ZSD_MOTHER_MST T1, ZSD_MOTHER_DTL T2, ZSD_MOTHER_VIA T3
WHERE T1.MANDT = T2.MANDT
AND T1.MVESSEL_NO = T2.MVESSEL_NO
AND T1.MVESSEL_NO = T3.MVESSEL_NO
AND T2.MVOYAGENUMBER = T3.MVOYAGENUMBER
AND T2.TRANSHIPMENTA <>' '
UNION
SELECT T1.MVESSEL_NO, T1.MVESSEL_NAME, T1.SHIPPINGLINE, T2.MVOYAGENUMBER,
T2.TRANSHIPMENTB AS TPORT, T2.ETDTSHIPMENTB AS ETD_TPORT,
T3.MVESSEL_SRL_NO,
T3.PORTOFDISCHARGE POD, T3.ETAPORT
FROM ZSD_MOTHER_MST T1, ZSD_MOTHER_DTL T2, ZSD_MOTHER_VIA T3
WHERE T1.MANDT = T2.MANDT
AND T1.MVESSEL_NO = T2.MVESSEL_NO
AND T1.MVESSEL_NO = T3.MVESSEL_NO
AND T2.MVOYAGENUMBER = T3.MVOYAGENUMBER
AND T2.TRANSHIPMENTB <>' '
This view i could not use from ABAP codes, ABAP/4 only identified by views which we would create from T-code se11. Now tell me how could I solve this issue. Because in this query i did some UNION which is not directly available in teh se11.
Please help me how to handle this situation. Because if I can use this sort of native sql views, I could solve lot of things in the development.

You can use real SQL to query non SE11 created database tables - look at the SAP help on EXEC SQL - but this is really not a good idea.  For example, it is database specific which removes one of the 'advantages' of SAP ie that it is portable between different database platforms;using SAP's Open SQL should mean that if your company moves to eg SQL Server it shouldn't be necessary to doing any re-coding whereas anything you've done in Oracle SQL will have to be re-coded. There are also other disadvantages of using real SQL eg you don't get any help from the syntax checker and I think you would bypass the whole SAP security level - SAP security is defined at application level and not via database grants.
I would bet a reasonable amount of money that there is nothing that you can do in real SQL that you can't replicate in SAP's Open SQL .  Ok the Open SQL solution might be a bit more convoluted and possibly less elegant but you can make it do the same thing.  If you want to stick with Oracle then I guess you should look for a job that uses Oracle rather than SAP.
