How to build dynamic select query

[Former Member]

Using the ZCO_SETTLE_CHK-REC_FIELD and DISTRIBUTION_RULE-KONTY write a dynamic select single query <table>-<field name> e.g. <COAS>- <AUART> on the <table> e.g. <COAS>. If the DISTRIBUTION_RULE-KONTY is u2018ORu2019, then use DISTRIBUTION_RULE-AUFNR value in the where clause of the query to fetch the ZCO_SETTLE_CHK-REC_FIELD value maintained in the <table>-<field name>. If DISTRIBUTION_RULE-KONTY = u2018KSu2019 or u2018PRu2019 use DISTRIBUTION_RULE-KOSTL or DISTRIBUTION_RULE- PS_PSP_PNR respectively in the where clause to fetch the values.

For above how we can build dynamic query

Hi,

Refer the below code which helps to design a dynamic where condition.

IF NOT p1 IS INITIAL.
CLEAR : lv_p1_condition.
CONCATENATE 'F1' ' = ' '''' p1 '''' INTO
lv_p1_condition.
ENDIF.
 
IF NOT p2 IS INITIAL.
CLEAR : lv_p2_condition.
CONCATENATE 'F2' ' = ' '''' p2 '''' INTO
lv_p2_condition.
ENDIF.
 
IF NOT p3 IS INITIAL.
CLEAR : lv_p3_condition.
CONCATENATE 'F3' ' = ' '''' p3 '''' INTO
lv_p3_condition.
ENDIF.
 
 
IF NOT lv_p1_condition IS INITIAL.
CONCATENATE lv_p1_condition lv_condition
INTO lv_condition SEPARATED BY space.
ENDIF.
 
IF NOT lv_p2_condition IS INITIAL.
IF lv_condition IS INITIAL.
CONCATENATE lv_p2_condition lv_condition
INTO lv_condition SEPARATED BY space.
ELSE.
CONCATENATE lv_condition 'AND' lv_p2_condition
INTO lv_condition SEPARATED BY space.
ENDIF.
ENDIF.
 
IF NOT lv_p3_condition IS INITIAL.
IF lv_condition IS INITIAL.
CONCATENATE lv_p3_condition lv_condition
INTO lv_condition SEPARATED BY space.
ELSE.
CONCATENATE lv_condition 'AND' lv_p3_condition
INTO lv_condition SEPARATED BY space.
ENDIF.
ENDIF.
 
 
SELECT * FROM link INTO wa
WHERE lv_condition .
