SAP連接外部ORACLE數據庫?
1.先在SAP底層ORACLE數據庫編輯TNS文件,一般由BASIS配置完成.配置完成后我們可以用事務碼:AL11查看配置是否正確,路徑:DIR_ORAHOME->network->admin->tnsnames.ora查看對應的TNS是否配置正確,如:

ORADB04.world =?
(DESCRIPTION =?
(ADDRESS_LIST =?
(ADDRESS =?
(PROTOCOL = TCP)?
(HOST = XXX.XXX.XXX.XXX)?
(PORT = 1521)?
)?
)?
(CONNECT_DATA =?
(SERVICE_NAME = XXXX)?
)?
)

2.在SAP中用DBCO配置,如下:

3.編寫ABAP程序實現SAP訪問外部ORACLE數據庫,并插入數據。?
有兩個例子：?
例子1：?
REPORT zljc_nativesql2 .?
DATA: p_dbname(10) VALUE ‘SIPS’.?
DATA: l_sql_error TYPE REF TO cx_sy_native_sql_error,?
l_error_text TYPE string.

TYPES: BEGIN OF ty_room,?
room_id(30),?
room_name(100),?
room_people(10),?
room_desc(100),?
END OF ty_room.

DATA: gt_room TYPE TABLE OF ty_room ,?
gs_room TYPE ty_room.

gs_room-room_id = ‘no-201’.?
gs_room-room_name = ‘風波亭’.?
gs_room-room_people = ‘5’.?
gs_room-room_desc = ‘岳武穆遺書’.?
APPEND gs_room TO gt_room.

gs_room-room_id = ‘no-202’.?
gs_room-room_name = ‘威虎山’.?
gs_room-room_people = ‘5’.?
gs_room-room_desc = ‘座山雕老巢’.?
APPEND gs_room TO gt_room.

gs_room-room_id = ‘no-203’.?
gs_room-room_name = ‘白宮’.?
gs_room-room_people = ‘29’.?
gs_room-room_desc = ‘美國總統府’.?
APPEND gs_room TO gt_room.

gs_room-room_id = ‘no-204’.?
gs_room-room_name = ‘鳥巢’.?
gs_room-room_people = ‘5’.?
gs_room-room_desc = ‘奧運會主場館’.?
APPEND gs_room TO gt_room.

gs_room-room_id = ‘no-205’.?
gs_room-room_name = ‘鳳儀亭’.?
gs_room-room_people = ‘5’.?
gs_room-room_desc = ‘貂蟬和呂布’.?
APPEND gs_room TO gt_room.

gs_room-room_id = ‘no-206’.?
gs_room-room_name = ‘偽皇宮’.?
gs_room-room_people = ‘5’.?
gs_room-room_desc = ‘偽滿皇帝’.?
APPEND gs_room TO gt_room.

TRY.?
EXEC SQL.?
CONNECT TO :p_dbname?
ENDEXEC.

CATCH cx_sy_native_sql_error INTO l_sql_error.?
CALL METHOD l_sql_error->get_text?
RECEIVING?
result = l_error_text.?
WRITE: AT /1 l_error_text.?
ENDTRY.?
IF sy-subrc <> 0.?
WRITE: /1 ‘連接到數據庫失敗:’, l_error_text ,’,請聯系管理員!’.

STOP.?
ENDIF.

TRY.?
LOOP AT gt_room INTO gs_room.?
EXEC SQL.?
insert into ljc_room?
( room_id,?
room_name,?
room_people,?
room_desc )?
values(:gs_room-room_id,?
:gs_room-room_name,?
:gs_room-room_people,?
:gs_room-room_desc)

? ?ENDEXEC.
?ENDLOOP.

CATCH cx_sy_native_sql_error INTO l_sql_error.?
l_error_text = l_sql_error->get_text( ).?
ENDTRY.?
“*操作Oracle數據庫時，異常處理?
IF NOT l_error_text IS INITIAL. “如果捕獲到異常，記錄日志，回滾?
CLEAR l_error_text.?
EXEC SQL.?
rollback?
ENDEXEC.?
ELSE. ” 如果無異常，提交插入數據?
EXEC SQL.?
commit?
ENDEXEC.?
ENDIF.

EXEC SQL.?
DISCONNECT :p_dbname?
ENDEXEC.
