How to avoid duplicates from the form

Question

when I'm enter MR number , all the data(Part number , Desc details) are displaying correct and then search for desc the duplicate data is displaying actually not duplicate, their MR number is different , but in the form we r showing only the Partnumber & Desc details. and its directly from the table.
this is the code for search the desc
DECLARE
WERE VARCHAR2(2000);
WERE1 VARCHAR2(1000);
FIND VARCHAR2(30);
BEGIN
     :GLOBAL.CODE :=:BLK_MR.SEARCH;
     GO_BLOCK('MR_SELECT_VIEW');
     --WERE :='WHERE MRD_CCNO =  '||TO_CHAR(:BLK_MR.MRNO)||' AND
-- ITEM_DESC LIKE '''||'%'||:GLOBAL.CODE||'%'||''' ORDER BY ITEM_DESC ';
MESSAGE(TO_CHAR(:BLK_MR.ITEM61));
MESSAGE(TO_CHAR(:BLK_MR.ITEM61));
     WERE :='WHERE MRD_CCNO IN ( SELECT VE_CC_NO FROM VE_MASTER WHERE VE_GROUP_CODE=
'||TO_CHAR(:BLK_MR.ITEM61)||'
AND VE_SUBGROUP_CODE='||TO_CHAR(:BLK_MR.VE_SUBGROUP)||')
AND ITEM_DESC LIKE '''||'%'||:GLOBAL.CODE||'%'||''' ORDER BY ITEM_DESC ';
MESSAGE(WERE);
MESSAGE(WERE);
     SET_BLOCK_PROPERTY('MR_SELECT_VIEW',ORDER_BY,'');
     SET_BLOCK_PROPERTY('MR_SELECT_VIEW',DEFAULT_WHERE,WERE );
EXECUTE_QUERY;     
END;
how to take the distinct partno from the table, since its is directly from the table.
b'cos its checking MR number as a where condition

HI!
I advise you to create one more block with data type=From clause And as Name nest select (select distinct....)... and then, make, for example on pressing the button change data type of the block:
set_block_property(block_name, QUERY_DATA_SOURCE_TYPE, get_block_property(block_name(with from clause), QUERY_DATA_SOURCE_TYPE));
set_block_property(block_name, QUERY_DATA_SOURCE_NAME, get_block_property(block_name(with from clause), QUERY_DATA_SOURCE_NAME));
