Drop Lists & SQL

Question

Forte Users,
Is there any method of putting an SQL response into a droplist?
Well, the only way I know is like the code below. But there's a problem.
Hope you can help me.
============
-- Insert value into DB
-- Table is : sigl_orgao varchar2 not null, numseq number not null, data
-- date
sql insert into DELHABILIDADE_ORGAO
values ( 'MG' , 1 , '' )
on session OracleDBSEssion;
-- Create Target Array for SQL
Orgao_Temp : Array of TextData = new;
-- Select from database into Orgao_Temp
-- The problem is here: if there is more then one row with identical
-- column value
-- forte raises an exception and says:
-- Select more than 1 row(s). The extra results were cancelled.
sql select sigl_orgao into :Orgao_Temp
from DEL_HABILIDADE_ORGAO
on session OracleDBSESSION;
-- Creat the list for setting the droplist
-- If the array Orago_Temp is OK, this code fragment works pretty well. I
-- tested it before.
Orgao_list : Array of ListElement = new;
cont : integer;
cont = 0;
for p in Orgao_Temp
do
cont = cont + 1;
OrgaoList[cont] = new ( IntegerValue = cont , TextValue=p.Value);
end for;
-- Set the droplist
<Orgao>.SetElementList(Orgao_List);
===================
Could anyone help me?

C.M.,
As to how to retrieve ListElement values from a database table,
another solution you may avail yourself of with Oracle is to use "column aliasing".
A listelement has several attributes: textvalue, integervalue, and objectvalue.
you can select directly into an array of listelement with a query of the form:
aListElement : ListElement = new;
sql select ORACLECOLUMN1 "integervalue",
ORACLECOLUMN2 "textvalue"
into :aListElement
from <table>
on session <session>;
or
result : array of ListElement;
sql select ORACLECOLUMN1 "integervalue", ORACLECOLUMN2 "textvalue"
into :result
from <table>
...and so on
The column aliasing assists the forte/dbms API to match attribute names to column names.
