hi,

http://www.susanto.id.au/papers/DynOpenSQL.asp

ex:

SELECT *

FROM (w_table)

INTO CORRESPONDING FIELDS OF wa_consolidate

WHERE kappl EQ wa_kona-kappl

AND kschl EQ wa_t6b2f-kschl

AND vkorg EQ wa_kona-vkorg

AND vtweg EQ wa_kona-vtweg

AND datbi GE p_datbi

AND knuma EQ wa_kona-knuma.

here table is select ed dynamically.

Hi

It means the table and where condition are managed dynamically in the program, so they aren't hardcoded.

DATA: tablename(30) TYPE c.

DATA: t_cond(1000) TYPE c OCCURS 0 WITH HEADER LINE.

DATA: wa TYPE REF TO data.
FIELD-SYMBOLS: <wa> TYPE ANY.

START-OF-SELECTION.

  tablename = 'BKPF'.

* Create a workarea
  CREATE DATA wa TYPE (tablename).
  ASSIGN wa->* TO <wa>.



  CONCATENATE 'BUKRS =' '''' '1000' '''' INTO t_cond.
  APPEND t_cond.


  CONCATENATE 'AND GJAHR = ' '''' '2008' '''' INTO t_cond.
  APPEND t_cond.

  SELECT * FROM (tablename) INTO <wa> WHERE (t_cond).
  ENDSELECT.

The query above it can write statically:

SELECT * FROM BKPF WHERE BUKRS = '1000'
                                         AND GJAHR = '2008'.
ENDSELECT.

The main difference is it can't use a SELECT-OPTIONS or RANGES in the dynamic sql, but the WHERE condition has to have constants value only.

The performance should be better for the static sql.
