From the document, i found
Find all rows with field_name > value:
field_name => ">value"
or field_name-gt => value
when i have a test , it return no link or even error.
$sth = $tab->select( { Timestmp => ">1" } ); #### no link return
or $sth = $tab->select( { Timestmp-gt =>'1' } ); #### error
while i got correct result using
my $condition = GT::SQL::Condition->new( 'Timestmp', '>', '1');
$sth = $tab->select( { blah blah blah} , $condition );
weather i got something wrong with the syntax in first block of the code ?
