Hi,
I experience a problem with the insertion of strings into a table. However,
this problem does not occur for all strings and there is no pattern or specific
character I could find that triggers the exception. Okay, here is what I do:
my $stmt_resultset = $this->{db_handler}->prepare_cached("insert into resultset(session_id, query_
+id, uri, domain, rank) values(?,?,?,?,?)");
$success = 1;
for(my $i = 0; $i < @resultset; $i++)
{
my $result = $resultset[$i];
$success &&= $stmt_resultset->execute($session_id,$query_id,
$this->{db_handler}->quote($result),$this->{db_handler}->quote($param4),$i+1 );
}
if($success)
{
$this->{db_handler}->commit;
print STDOUT "..committed" if debug;
}
else
{
$this->{db_handler}->rollback;
print "Couldn't store resultset: " . $this->{db_handler}->errstr . "\n";
}
Alternatively, I already tried to use bind_param, e.g., as in
# $stmt_resultset->bind_param(1, $session_id, SQL_INTEGER);
# $stmt_resultset->bind_param(2, $query_id, SQL_INTEGER);
# $stmt_resultset->bind_param(3, $result, SQL_VARCHAR);
and call execute without arguments which however does not work as well.
Here is a sample of the error I get:
DBD::PgPP::st execute failed: ERROR: syntax error at or near "www" at character 133
This is when trying to insert a URL, however, when inspecting the database I find that
some urls could have been written, and I cannot make up a pattern or specific character
that is the reason - I also increased the size of the column definition
without any effect.
Has anyone an idea what the cause of this error might be - how to fix it?
Thanks a lot for your help,
Julia
