I can't believe it ... and there is not a trace of this in IBO? Very strange ... so I need to grab IBO's DLL handle and get the function address myself, OK ... I can do it ... but I am still shocked. Why don't you ask Jason on the IBO mailing list? Maybe he's already got a solution ready for you. And if not then I assume he'll be eager to fix this.

What is the character set of your connection -- IBExpert vs Java application? Maybe that's where they differ. HTH, Markus [Non-text portions of this message have been removed]

And be careful of the layout of your records. For example, if you sandwich your CHAR[1] between two integer columns, you'll get three bytes of padding so the integers align on natural boundaries. Out of curiosity: Can the sandwich problem be controlled via alter position? IOW does column position affect the record layout on disk? [Non-text portions of this message have been removed]
Re: [firebird-support] Newbies queries on type of data files and recovery options

What are the common scenarios of a Firebird data file getting corrupt? In case of a single-file structure, I guess no other files need to be backed up? In over ten years the only corruptions I've seen were due to 1) Full hard disk: IIRC in this case Firebird will overwrite the file from the beginning. Not good, but checking for free space on every write would slow down writes too much. Just make sure you have enough space. 2) Sudden power loss: Normally Firebird will just throw away the last unfinished transaction, sometimes a quick (seconds in my cases) repair with gfix tool was needed. 3) Not really a corruption but it comes up here occasionally so I'll mention it: You can add a NOT NULL column to an existing table that already contains records. Then it's up to you to fill that column with values, or else Firebird will complain when you next *restore* the database from a backup. But there's a command line switch to ignore that complaining, so it's not a big problem. HTH, Markus

Not good, but checking for free space on every write would slow down writes too much. Just make sure you have enough space. This is far from true. Overwriting was an issue in Interbase 5.x. Lack of free space was solved with pre-allocation in recent Firebird versions - it will raise non-critical error. Thanks for the correction. I knew it was a long time ago =)
Re: [firebird-support] Migration from 2.1 UNICODE_FSS to 2.5 UTF8

I just don't know how to solve this problem... The database migration process might require some special steps. If the database restore fails with the error malformed string for you, please pay attention to the files in the /misc/upgrade/metadata directory of your installation and use the new -fix_fss_data and -fix_fss_metadata command line switches of GBAK. quoted from: http://www.ib-aid.com/articles/item118 Read the docs mentioned above (/misc/upgrade/metadata).

Re: [firebird-support] Timer in firebird?

There are different clients connected, for each I need this function. Howdy, AFAIK there is no functionality to do this from inside the database. Can you tell us what you're trying to achieve? Maybe there is another way to do what you want. E.g. I needed to count the number of client applications already connected to the database at application startup: The client which needed that number would post an event for which all clients were listening. When received every client would insert a record into a table which could then be counted. If you're just interested in all connections to the database you could use the monitoring tables in newer versions of Firebird (MON$ATTACHMENTS), see here: http://www.ibphoenix.com/resources/documents/search/doc_3 Or maybe you could use an ON CONNECT trigger: http://www.firebirdsql.org/refdocs/langrefupd21-ddl-trigger.html HTH, Markus
