RE: switching to a different database from a DSN
Some databases allow you to share tables form others, so you could try that, I think that it is called a Database Link. -Original Message- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED]] Sent: 11 July 2001 14:18 To: [EMAIL PROTECTED] Subject: switching to a different database from a DSN Hi all, I am using DBI::ODBC on windows platform to access Informix database. I defend database x when I created the DSN. Is there a way to switch to a database different from the one defined when creating the DSN. In other words use the same DSN to access all the database on the same database server. $dbh = DBI-connect(dbi:ODBC:myDSN,,,\%attr);
RE: Array problem
If this is going to be included in a Dropdown then you'll need to do
something like :
print option$cc[2]/option

Subject: Array problem
This might not strictly be a DBI problem so I apologise in advance.
I'm writing an enquiry form and want to have some dropdown
lists built from the DB so I'm doing a select and then
assigning it to an array
using push - sample code below...
while (@data = $sth-fetchrow_array())
{
push (@cc,@data);
}
The problem I've got is I can print the values of the new
array in IE but not Netscape and I can't see why. Does
Netscape have some
sort of limit coz one of the selects is getting aound 6500 elements.
I'd appreciate any help you can give me coz I've been stuck
on this for about 2 days.
Chris

RE: Slow execution
How often is the data changed ? Is it required to be 'real time' ? If not, then perhaps you could use a snapshot rather than a big query ? have you tried using indexes as well ? -Original Message- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED]] Sent: 12 June 2001 14:29 To: [EMAIL PROTECTED]; [EMAIL PROTECTED] Subject: RE: Slow execution I am also facing this kind of stuff. But I see the problem in SELECT only. I am joining 6 tables some of them from other databases. and when I run the query on SQL client it takes time but not that much the perl DBI is taking. ofcourse my oracle database contains millions of records. Is that the problem?
