RE: [firebird-support] Migrate from 1.5 to 2.1 or 2.5: Which is the best choice?
I'm evaluating the choice of migrating a 1.5 Firebird database either to 2.1 or to 2.5. I've readed the release notes of both versions but I can't find no elements that help to decide which one could be best choice. Personally, I upgraded from 2.1 to 2.5.1 because of the new features I needed to take advantage of. I have ditched FreeUDFLib. I have also started using temporary tables to speed up certain complicated queries, that would otherwise have been too slow to implement. I've tested the client application with both versions (2.1 and 2.5) and it seems to work fine. My questions are: - Is there any good reason for not migrating to 2.5 and migrate to 2.1? Personally, I would just use the latest version, but I have recently had a Debian customer point out that there isn't a stable 2.5.1 build for them yet. - Should I jump directly to 2.5, keeping in mind that SQL and data contents migrating issues could be almost the same in both versions? I recently changed from 2.1 to 2.5.1 and had no issues with anything needing to be changed on my side. - Has somebody any application running Delphi BDE components using Firebird 2.5? Sorry, I use Delphi XE2 and FIBPlus data access components. Hope that helps somewhat! Maya

[firebird-support] Updating Null Column values Will Raise an Exception -605
ENDDATE is date and was created after the table being created and it allows nulls so it filled the colum with nulls. So i want to set ENDDATE then i do : UPDATE MYTABLE SET ENDDATE=CURRENT_DATE WHERE MYID=1 Error -605 value null This wasnt supposed to happen ? It should Set RowID MYID primarykey ENDDATE with the CURRENT_DATE .The problem yet is in the IBOConsole and My Application Components if i change it manualy it accepts it with no problem only Update Query Problem ? So client Drivers dot use Sql ? I dont undestand wheres the problem.

Replication is another option, but adds some complexity. see you !

I think you should also think about encryption os transmitted data, or is something new I don't know about Firebird yet ( I'm stuck with version 1.5) ? Boguslaw

Internet has higher latency, which is nog very good for Firebird's chatty protocol, but it does work. You need to make sure all firewalls open port 3050 (or whatever port you choose for your FB server). You also need to make sure the clients know where the server is, i.e. its hostname or its IP address. This would normally be done either by using a regular domain name like yourcompany.com or if you don't have a domain name, simply make sure the server has a fixed IP address (most ISP:s provide this service at a low extra cost). Now, the data will travel over the internet unencrypted, so you either need to decide that this is no problem (not sensitive data) or establish a VPN or secure tunnel, e.g. using Zebedee as mentioned earlier. This might slow down the connection a bit further, depending on your situation and setup. If the data traffic is too slow, due to the combo of high latency internet and FB's chatty protocol, you can write an extra tier/layer/server thingy that executes on the same machine as the FB server and handles all communication with the actual database server. Your clients would talk to your server thingy instead, hopefully using a more efficient protocol. Kjell Vishal wrote: ...

[firebird-support] Is there an auto-conversion for text blobs while reading with isc_get_segment?
Hi, is there an auto conversion from the character set of a text blob to the encoding set for the connection? For example, what happens if my client connection character set is UTF-8, but the text blob column has ISO-8859-1? Did isc_get_segement() return UTF-8 data or ISO-8859-1? As far as I understand the Interbase API manual, I need to setup a filter. But how can this be done? I assume something like this: isc_blob_lookup_desc(); // prepare from_desc; isc_blob_default_desc(); // prepare dest_desc; unsigned char bpb[20]; unsigned short actual_len; isc_blob_gen_bpb(sv, to_desc, from_desc, sizeof(bpb), bpb, actual_len); But I don't see how this get the connection encoding? The description for isc_blob_default_desc() tells me: [...] Character set is set to the default character set for the process or database. [...] But isc_blob_default_desc() has no database handle param or something else which can be used to resolve the connection encoding. So I think this is the wrong way. I'm also a little bit confused by the fact that the DPB for isc_attach_database() (option isc_dpb_lc_ctype) requires a string like UTF-8 but the isc_bpb_target_interp option in the BPB requires an integer ..hhuuu? -- Daniel Vogelbacher web: http://daniel.vogelbacher.name irc: cytrinox @ (freenode|ircnet|quakenet) www.informave.org
