I'm a newbie myself, but if I understand you correctly, you just need to
check if the SQL query returns a defined value?
simply:
if (!defined($sql)){
do something...
}
else {
do something else
}
or:
print sorry if !defined($sql);
print Yippee if defined($sql);

Subject: Testing for truth
List,
I would like to be able to test my SQL query for truth. To do this I would
like to be able to do a SELECT query and if the colunm contains nothing I
would like my script to be able to return and tell me this. As an example.
if I do a SELECT statement as follows
SELECT test FROM support WHERE unique_id ='1234'
If test = '(NOTHING)' print Sorry the search retuned no results please
search again.
elsif test = 'hello world' print here are the results for your search.
I can do this exact same thing if I am searching with numeric values such as
data and time. But can't seem to return a true statement if the column
contains some words?
Any ideas?
Thanks in advance.
Regards,
Daniel Falkenberg
