Checking conditions in SELECT statement

[Former Member]

Hi All,

I am relative new to ABAP and I would like to ask a question about checking conditions in SELECT statement in the "WHERE" part.

There are two checkboxes at the selection screen and each should disable one of conditions (marked with two stars) in the SELECT mentioned below.

My question is, whether there exists an option how to solve this problem without using solution like:

IF checkobx1.

SELECT (without one condition)

ELSEIF checkbox2.

SELECT(without other condition).

ELSE.

SELECT (with both conditions)

SELECT q_{prueflos q}herkunft q_{aufnr q}sa_aufnr q_{matnr q}werkvorg

q_{pastrterm q}paendterm

q_{verid q}objnr v_{objnr AS objnr_fa v}auart

FROM qals AS q INNER JOIN vkaufk AS v

ON q_{aufnr = v}aufnr

INTO CORRESPONDING FIELDS OF TABLE gt_qals

WHERE q~prueflos IN s_pruefl

AND q~stat35 EQ space

AND q~werk EQ loswk

AND q~herkunft IN s_herk

• AND q~offennlzmk EQ 0

• AND q~offen_lzmk EQ 0

AND q~pastrterm IN s_startt

AND q~paendterm LE s_endt

AND v~auart IN s_auart. "('ZCPA', 'ZCPK', 'ZCBA').

Hi

U can try to use the ranges:

RANGES: R1 FOR QALS-OFFENNLZMK,
                R2 FOR QALS-OFFEN_LZMK.


IF CHECKBOX1
  R1(3) = 'IEQ'.
  R1-LOW = 0.
  APPEND R1.
ELSEIF CHECKBOX2.
  R2(3) = 'IEQ'.
  R2-LOW = 0.
  APPEND R2.
ENDIF.

SELECT ........................................
  WHERE 
      ...............................................
      AND OFFENNLZMK IN R1
      AND OFFEN_LZMK IN R2
      ...............................................

Hi,

You can build the where clause dynamically and pass it to the select statement. Take a look at the program demo_select_dynamic_conditions in SE38.

Hi,

If u write someother logic for ur requirement, definetly there will be a select query.

In ur logic also, ultimately only one Select query will be executed. so performance will be the same if u use some other logic aslo. So use ur logic.

You can solve the problem with dynamic creation of condition in where list

first add all mandatry values

ex: "q~prueflos IN s_pruefl" add to itab_sel_final

"AND q~stat35 EQ space" add to itab_sel_final

"AND q~werk EQ loswk" add to itab_sel_final

"AND q~herkunft IN s_herk" add to itab_sel_final

then add those check box which is selected

suppoese check1 = X then add

"AND filed = check1" add to itab_sel_final

So decide your where condtion in internal table ITAB_SEL_FINAL and then use in select statement

SELECT q_{prueflos q}herkunft q_{aufnr q}sa_aufnr q_{matnr q}werkvorg

q_{pastrterm q}paendterm

q_{verid q}objnr v_{objnr AS objnr_fa v}auart

FROM qals AS q INNER JOIN vkaufk AS v

ON q_{aufnr = v}aufnr

INTO CORRESPONDING FIELDS OF TABLE gt_qals

WHERE (itab_sel_final).

Hope this will solve your problem.

Hi,

With this, I think u can directly read into WHERE clause

IF checkbox1.
 
    v_where = '& BETWEEN ''&'' AND ''&'' '.
    REPLACE '&' WITH key_field INTO v_where.
    REPLACE '&' WITH field_LOW INTO v_where.
    REPLACE '&' WITH field_HIGH INTO v_where.
    CONDENSE v_where.

ELSEIF  checkbox2.

    v_where = '& BETWEEN ''&'' AND ''&'' '.
    REPLACE '&' WITH key_field INTO v_where.
    REPLACE '&' WITH field_LOW INTO v_where.
    REPLACE '&' WITH field_HIGH INTO v_where.
    CONDENSE v_where.

ENDIF.

select * into corresponding fields of table ITAB
             from (table_name)
            where (v_where).

In this key_field is your fieldname in the where clause and field_low, field_high are range of values.

If i write static query it looks like this

RANGES: MATNR1 FOR MARA-MATNR.

  MATNR1-LOW = MATNR_LOW.
  MATNR1-HIGH = MATNR_HIGH.
  MATNR1-SIGN = 'I'.
  MATNR1-OPTION = 'BT'.
  APPEND MATNR1.


select * into corresponding fields of table itab
from mara where matnr BETWEEN 'M100' AND 'M200'.

Hope it helps u

thanks\

I would like to thank you all for your helpfull solutions.

At last I was told to solve this problem by deleting those two conditions and add an statement like this:

IF sy-subrc = 0.

SELECT * FROM QALS INTO ls_tab

FOR ALL ENTRIES IN gt_qals

WHERE prueflos = gt_qals-prueflos.

CHECK ls_tab-offennlzmk EQ 0 AND p_allow1 EQ ''.

CHECK ls_tab-offen_lzmk EQ 0 AND p_allow2 EQ ''.

DELETE gt_qals WHERE prueflos = ls_tab-prueflos.

ENDSELECT.

ENDIF.
