A simple program that show how to read data from Microsoft Access.
In this case we read data from MS Access Table: PA0001 with 2 field: PERNR and Name.
MS Access file is: Data.mdb and saved in drive C.

Type and Data declaration:

Code:
TYPE-POOLS OLE2.

DATA: CONN      TYPE OLE2_OBJECT,
          RSDB      TYPE OLE2_OBJECT,
          SQL        TYPE C LENGTH 1024.

DATA: BEGIN OF WA_TEMP,
            VALUE TYPE C LENGTH 1024,
          END OF WA_TEMP,
          IT_TEMP LIKE STANDARD TABLE OF WA_TEMP.
DATA: BEGIN OF WA_PA0001,
            PERNR TYPE PERSNO ,
            ENAME TYPE EMNAM,
          END OF WA_PA0001,
          IT_PA0001 LIKE TABLE OF WA_PA0001.


Create ADODB Object:

Code:
START-OF-SELECTION.

  CREATE OBJECT CONN 'ADODB.Connection'.
  CREATE OBJECT RSDB 'ADODB.Recordset'.
 


Set connection and run query:

Code:
* MDB Connetion infomations
  CONCATENATE 'Provider=Microsoft.Jet.OLEDB.4.0;'
  'Data Source=C:\Data.mdb;'
  INTO SQL.

  CALL METHOD OF CONN 'Open' EXPORTING #1 = SQL.

* Query Statement ...
  SQL = 'SELECT * FROM PA0001'.

* Run Query
  CALL METHOD OF RSDB 'OPEN'
    EXPORTING #1 = SQL
    #2 = CONN
    #3 = '1'.


Save records into internal table:

Code:

DO.
    CALL METHOD OF RSDB 'getstring' = SQL
    EXPORTING #1 = '2' "Do not modify!
    #2 = 1    "Do not modify!
    #3 = '|'  "Do not modify!
    #4 = '|'. "Do not modify!

    IF SY-SUBRC EQ 0.
      REFRESH IT_TEMP.

      SPLIT SQL AT '|' INTO TABLE IT_TEMP.
      LOOP AT IT_TEMP INTO WA_TEMP.
        CASE SY-TABIX.
          WHEN 1.
            WA_PA0001-PERNR = WA_TEMP-VALUE.
          WHEN OTHERS.
            WA_PA0001-ENAME = WA_TEMP-VALUE.
        ENDCASE.
      ENDLOOP.
      APPEND WA_PA0001 TO IT_PA0001.
      CLEAR WA_PA0001.
    ELSE.
      EXIT.
    ENDIF.

  ENDDO.


Display data:

Code:

ULINE AT (55).
  WRITE: / '|' NO-GAP, (010) 'N I K'   LEFT-JUSTIFIED,
           '|' NO-GAP, (040) 'N A M E' LEFT-JUSTIFIED,
           '|'.
  ULINE AT /(55).
  LOOP AT IT_PA0001 INTO WA_PA0001.
    WRITE: / '|' NO-GAP, (010) WA_PA0001-PERNR   LEFT-JUSTIFIED,
             '|' NO-GAP, (040) WA_PA0001-ENAME   LEFT-JUSTIFIED,
             '|'.
  ENDLOOP.
  ULINE AT /(55).
