如何在SAP云平台ABAP编程环境里创建自己的Z表

选中ABAP包，右键创建一个新的Database Table：

 

 

 

 

 

维护表名为ZBOOKING:

 

 

表实现的源代码：

@EndUserText.label : 'Jerry''s booking'
@AbapCatalog.enhancementCategory : #NOT_EXTENSIBLE
@AbapCatalog.tableCategory : #TRANSPARENT
@AbapCatalog.deliveryClass : #A
@AbapCatalog.dataMaintenance : #LIMITED
define table zbooking {
  key client         : abap.clnt not null;
  key booking        : abap.int4 not null;
  customername       : abap.char(50);
  numberofpassengers : abap.int2;
  emailaddress       : abap.char(50);
  country            : abap.char(50);
  dateofbooking      : timestampl;
  dateoftravel       : timestampl;
  @Semantics.amount.currencyCode : 'zbooking.currencycode'
  cost               : abap.curr(15,2);
  currencycode       : abap.cuky;
  lastchangedat      : timestampl;

}

激活：

 

 

下一步，创建一个ABAP类，以代码的方式往Z表里插入数据。

这个ABAP类要实现if_oo_adt_classrun接口，类似Java里的console应用：

 

 

完整代码：

 

 

CLASS zcl_data_generator DEFINITION
  PUBLIC
  FINAL
  CREATE PUBLIC .

  PUBLIC SECTION.
    INTERFACES if_oo_adt_classrun.
  PROTECTED SECTION.
  PRIVATE SECTION.
ENDCLASS.


CLASS zcl_data_generator IMPLEMENTATION.

  METHOD if_oo_adt_classrun~main.
    DATA:it_bookings TYPE TABLE OF zbooking.

*    read current timestamp
    GET TIME STAMP FIELD DATA(zv_tsl).
*   fill internal table (itab)
    it_bookings = VALUE #(
        ( booking  = '1' customername = 'Jerry' numberofpassengers = '3'
          emailaddress = '[e-mail]'
          country = 'China' dateofbooking ='20190213125959' dateoftravel ='20190213125959'
          cost = '546' currencycode = 'EUR' )
        ( booking  = '2' customername = 'Tom' numberofpassengers = '1'
          emailaddress = '[e-mail]'
          country = 'USA' dateofbooking ='20190313125959' dateoftravel ='20190313125959' cost = '1373' currencycode = 'USD' lastchangedat = zv_tsl )
     ).

    DELETE FROM zbooking.

    INSERT zbooking FROM TABLE @it_bookings.

    SELECT * FROM zbooking INTO TABLE @it_bookings.
    out->write( sy-dbcnt ).
    out->write( 'data inserted successfully!').

  ENDMETHOD.

ENDCLASS.
