Answer 1

SELECT DNAME,TO_CHAR(DEPTNO) FROM DEPT;This is the format of the query required to populate a list item,
where the first column value is the one that appears in the list of values
and the second column value is the one that will get saved in the database or that will be the value of the list item.
Just try using follwoing in WHEN-VALIDATE-ITEM trigger for list6
message (:block3.list6)
The message will be deptno and not the dname
now values has been populated in the list.but can u explain me whats wrong with my previous query?
SELECT DNAME FROM DEPT;why dint it help me to pop values in the list?.This query has just one column not as required.
Hope its clear.
