Re: [libreoffice-users] Calc suddenly very slow on loading
Hi all: I think it would be because you have low memory asigned for your big spreadsheet. I suggest this: 1) Menu 2) Tools 3) Memory There you find some topics where you can increase the memory that Libre Office use for the program. If you increase them your Libre Office able to manage more data and information in each spreasheet.

Re: [libreoffice-users] Re: Where is Base?
Hi :) Yeh, in attempting to clarify i did add an extra confusion! Sorry! The HsqlDb version 1.8 is only a problem when using the internal version in Base.

[libreoffice-users] database2spreadsheet
Hi, how would I create a spreadsheet from a table in a database? I know I can copy and paste, and I want to avoid that. Basically, users should be able to click an icon in LO (or on their desktop) and be presented with a spreadsheet which displays an export from a table I have in a mysql database. Fields in the spreadsheet must be in a different order than in the database and be formatted to a pre-defined width. In a future step, I would like to integrate graphics into the spreadsheet which could be created by a perl script with gnuplot from data in the database; the images could reside in a directory and rows in the database would have a field referring to the file name of the image. Is there any functionality in LO to achieve something like this, or is the database part as incompatible to other parts of LO, like spreadsheets, as it seems to be? -- To unsubscribe e-mail to: users+unsubscr...@global.libreoffice.org Problems? http://www.libreoffice.org/get-help/mailing-lists/how-to-unsubscribe/ Posting guidelines + more: http://wiki.documentfoundation.org/Netiquette List archive: http://listarchives.libreoffice.org/global/users/ All messages sent to this list will be publicly archived and cannot be deleted

He has cleared-up several mysteries by explaining the problems under the bonnet. It has also been good to see experienced and knowledgeable people giving anecdotal confirmation of Andreas' points.

Re: [libreoffice-users] Re: Where is Base?
Hi :) I think Noel ( Marion)'s good experience of H2 being sooo much better than Base is purely down to them moving away from the internal back-end in Base. The version of HsqlDb mentioned by Noel is the 1.8 which Andreas identified as being the version used as the internal back-end in Base. People using HsqlDb as an external back-end would have been pushed into upgrading many times in the last decade or so. Not upgrading would have been a lot like sticking with Win98. So i believe it was the move to a more modern version of a database program that gave Noel the fantastic improvements he experienced. Java-based back-ends do have a reputation for being much faster for the relatively small databases that most of us probably use. The one with 1 billion records might well find that moving to something heftier such as Postgresql or MySql/MariaDb does the trick. Although there might be some performance advantages to moving from the heftier back-ends to the smallerfaster ones there are several disadvantages around doing the move. Internet facing Servers using LAMP or WAMP and web-hosting companies tend to already have MySql/MariaDb (hence the M i think) so it'd be a bit like installing a different Office Suite for each document rather than trying to stick with just 1 or 2.

Re: [libreoffice-users] Re: Where is Base?
Hi :) One point that may have become muddled in translation is that it is only the front-end that needs to be copied, or re-created on multiple machines. The stable back-end could be on a server so that everyone is using the same data. As one person adds data everyone else would be able to see that data on their various machines. So Base is a LOT more scalable much more easily than Access. On a single machine you probably keep the back-end on the same machine as the front-end. If other machines get added then they just share that same back-end. As the company grows and eventually needs it's own internal server that back-end might get moved to that server but all the front-ends on all the different machines still keep using that same back-end even though it's been moved. Hopefully Base can even connect to back-ends hosted on WANs rather than just LANs and even on remotely hosted websites and Clouds.

Hello Tom... Maybe I misunderstand your remark below, but... My database has for years been on a WAN-accessed MySQL server. This is only an issue resolved through DNS or the hosts file .

The only issue I have at this time is that scrolling through tables/views under LO tends to be slow. I'll have to look at that...

This is not supported directly by LO, so you have a few options.
1. Do it manually
2. Copy from something that does and paste the code into your document
3. Use something like the code colorizer extension
(http://extensions.libreoffice.org/extension-center/code-colorizer-formatter)
and hope that it supports your language. What language are you using?
