How to implement FROM_UNIXTIME() like function in Firebird
Here is the example explained in Spanish :
select dateadd(second, 1255033470, cast(’01/01/1970 00:00:00.0000′ as timestamp)) from rdb$database;

Proposal for Firebird 3.0: Ditch the NONE as default charset
After some hot discussion in Firebird-Java, I want to propose to ditch
the NONE as default character set for newly created databases when no
database charset is specified.

Jaybird undocumented tip : Is there any way to set socket timeouts?
Is there any way to set socket timeouts?
Roman Rokytskyy answered :
-Yes, the property is called so_timeout and is directly passed when the socket is opened (see Socket.setSoTimeout documentation). You can append the property to the JDBC URL after question mark:
jdbc:firebirdsql:myhost/3050:/path/to/db.fdb?so_timeout=12345
– I have added this feature on request for some very special case. In general you don’t need this property, since the server is not supposed to crash and the network is not supposed to break as well, at least not for database applications. So, the solution is to solve the crash, not to add a workaround for it.
ps: soon it will be added to documentation
ANN: 2 new Trace API / FBTM screencasts: Parametrized query detection and enhanced error tracing
Two new Trace API / FB TraceManager screencasts have been made available:
The first is discussing the usage of the Trace API to detect
parametrized query reusage, which allows to check if you are re-using prepared statements in e.g. batch processing scenarios or not.
The second demo discusses the new error/warning tracing capabilities to
be expected in Firebird 2.5.2(http://tracker.firebirdsql.org/browse/CORE-3539) and its integration/usage in FB TraceManager.
An ODBC driver for Firebird on MacOSX
Via Paul Beach Blog
I was recently contacted by a Firebird user on MacOSX who was trying to get the Firebird ODBC driver to build on MacOSX. I thought I would try and step in to help.
For those of you who follow the CVS checkins for OdbcJdbc you might have noticed the addition of a number of a new directory in the Builds directory called Gcc.darwin containing a makefile, a readme and a .sh file to create a lipo’ed dylib. The driver sucessfully builds and passes some simple tests. Feel free to contact me for a copy of the dylib to test further.
The readme contains the following information
Dozens of new options for Firebird and .NET Framework
Hey!
If you have ever worked with Firebird or Interbase using the standard .NET provider for OLE DB (System.Data.OleDb), you will have likely encountered issues like this:
- The necessity to add ALL parameters manually.
- Even though the OLE DB provider supports parameter generation for commands, the .NET provider doesn’t use it, so you as the programmer must do that work on your own.
- The lack of support for named parameters. Although they actually exist, using them in reality requires a whole set of complex manipulations (the steps needed to add a parameter to a collection, etc.).
- The impossibility of using multiple DataReader objects at the same time (Multiple Active Result Sets).
- No execution of SQL scripts which contain several SQL expressions per command.
This list of difficulties a .NET developer has to deal with is far from complete.
Now it’s all different in a fundamentally new ADO.NET Data Provider for OLE DB
