Take two tables 

1) zajay_stu

        



2) zajay_stu1

                        



Apply inner join

 @AbapCatalog.sqlViewName: 'ZST_INNER'

@AbapCatalog.compiler.compareFilter: true

@AbapCatalog.preserveKey: true

@AccessControl.authorizationCheck: #NOT_REQUIRED

@EndUserText.label: 'student innerjoin'

define view zast_inner as select from zajay_stu as a

inner join zajay_stu1 as b

on a.zst_id = b.zst_id

{

key a.zst_id as ZstId,

a.zst_name as ZstName,

a.zst_dept as ZstDept,

a.zst_fee as ZstFee,

b.zst_fn as ZstFn,

b.zst_ln as ZstLn

}


output

      



Apply Left outer join


@AbapCatalog.sqlViewName: 'ZST_INNER'

@AbapCatalog.compiler.compareFilter: true

@AbapCatalog.preserveKey: true

@AccessControl.authorizationCheck: #NOT_REQUIRED

@EndUserText.label: 'student innerjoin'

define view zast_inner as select from zajay_stu as a

left outer join zajay_stu1 as b

on a.zst_id = b.zst_id

{

key a.zst_id as ZstId,

a.zst_name as ZstName,

a.zst_dept as ZstDept,

a.zst_fee as ZstFee,

b.zst_fn as ZstFn,

b.zst_ln as ZstLn

}


output:


          




Right outer join


@AbapCatalog.sqlViewName: 'ZST_INNER'

@AbapCatalog.compiler.compareFilter: true

@AbapCatalog.preserveKey: true

@AccessControl.authorizationCheck: #NOT_REQUIRED

@EndUserText.label: 'student innerjoin'

define view zast_inner as select from zajay_stu as a

right outer join zajay_stu1 as b

on a.zst_id = b.zst_id

{

key a.zst_id as ZstId,

a.zst_name as ZstName,

a.zst_dept as ZstDept,

a.zst_fee as ZstFee,

b.zst_fn as ZstFn,

New syntax for append- VALUE (new syntax 7.4+) in ABAP

Image
* We use APPEND statement to insert the records at the last of the internal table. * In SAP ABAP new syntax, we can use VALUE expression instead of APPEND statement. * Value expression is a powerful mechanism to declare as well as initialize the internal tables. * It is a powerful utility where we can achieve the result with minimal coding. * Value expression is of 2 types.      -  Define the type before using it with VALUE keyword. The type defined is structure type  or table type.      -  Using # character for type and use it with VALUE keyword. Report REPORT  zab_rp_append_value . TYPES :  BEGIN  OF  ls_stu ,          st_id ( 10 )    TYPE  n ,          st_name ( 15 )  TYPE  c ,         END  OF  ls_stu . DATA :  lt_stu  TYPE  TABLE...

Read statement new syntax in ABAP. (7.4+).

Image
*  Before ABAP 7.4, we used READ TABLE statement to read the first matching record from the internal table  based upon key or index . * In SAP ABAP new syntax, instead of READ TABLE , we can use the table expressions. * We need to use the square bracket [ ], In the square bracket, we need to specify the key or index. * While using table expression, If the table entry does not exist, system throws the exception CX_SY_ITAB_LINE_NOT_FOUND. * Use line_exists statement to check the existence of a record. Report REPORT  zab_rp_read_new . TABLES :   vbak . SELECT-OPTIONS :   s_vbeln  FOR  vbak - vbeln . SELECT  vbeln , erdat , erzet , ernam , auart         FROM  vbak         INTO  TABLE  @DATA ( lt_vbak )          WHERE  vbeln  IN  @s_vbeln . WRITE :   'Index value'  COLOR  5 . READ  T...
