Return value for Direct OBPM SQL Query in OBPM 10GR3

Question

Hi all,
I use a direct SQL Query provided by OBPM 10GR3 in my automatic activity to select certain elements from the db. The query is as follows:-
foreach (element in
SELECT id FROM TESTTABLE WHERE requestId = 732 and status = 1 )
// statements
logMessage("-- The id is-->" +element.id);
This only returns when the id is found in the db but returns nothing when not found in db?
How can I always get a return value? atleast a true or false, so that I can put IF statements?
Because if it returns nothing, the loop does not execute {}? So we cannot put something like:-
foreach (element in
SELECT id FROM TESTTABLE WHERE requestId = 732 and status = 1 )
logMessage("-- The id is-->" +element.id);
if(element.id == null)
logMessage("-- Id Not Found -->" );
else
logMessage("-- Id Found -->");
How can I always get a return value from my OBPM direct query ?
Remember , I am not using DynamicSQL in this case?

Hi,
Set a Boolean flag value to False before the SQL query.
Some thing like:
boolean flag = false;
foreach (element in
SELECT id FROM TESTTABLE WHERE requestId = 732 and status = 1 )
logMessage("-- The id is-->" +element.id);
flag = true;
if(flag) {
logMessage("-- Id Found -->" );
else
logMessage("-- Id Not Found -->");
Hope the above logic would work fine.
