ABAP code example for Function Module DD_FORKEY_SQLSTATEMENT

The ABAP code below is a full code listing to execute function module DD_FORKEY_SQLSTATEMENT including all data declarations. The code uses the latest in-line data DECLARATION SYNTAX but I have included an ABAP code snippet at the end to show how declarations would look using the original method of declaring data variables up front. This will allow you to compare and fully understand the new inline method. Please note some of the newer syntax such as the @DATA is not available until a later 4.70 service pack (SP8).

DATA:
it_statement  
 
 TYPE STANDARD TABLE OF DDWHERECND,"TABLES PARAM
wa_statement
 
 LIKE LINE OF it_statement

SELECT single TABNAME 
  FROM DD02L 
  INTO @DATA(ld_table_name).

 

SELECT single FIELDNAME 
  FROM DD03L 
  INTO @DATA(ld_field_name).

ABAP code to compare 7.40 inline data declaration with original syntax

The below ABAP code uses the older none in-line data declarations. This allows you to see the coding differences/benefits of the later inline syntax. It may also be useful if you are using an older version of SAP as some of the newer syntax above, such as the @DATA is not available until 4.70 EHP 8.

DATA:

ld_table_name
 
 TYPE DD02L-TABNAME ,
it_statement
 
 TYPE STANDARD TABLE OF DDWHERECND ,
wa_statement
 
 LIKE LINE OF it_statement,
ld_field_name
 
 TYPE DD03L-FIELDNAME ,
ld_syst_mandt
 
 TYPE DDREFSTRUC-BOOL .



SELECT single TABNAME 
  FROM DD02L 
  INTO ld_table_name.
 

"populate fields of struture and append to itab
append wa_statement to it_statement.

SELECT single FIELDNAME 
  FROM DD03L 
  INTO ld_field_name.
