Firebird(Client) with Silverlight

I tried build FirebirdClient in Silverlight environment and I failed. I expected to fail after some attempts with modifications and using only subset of features like i.e for Compact Framework, but this was really fast. Silverlight is only subset of .NET Framework. And one crucial part is not there, it’s System.Data stuff and without it you can drop major part of any ADO.NET provider’s code.

HowTo Show time after execution in isql after a query

Claudio answered to a “new feature” request

This command exists in all Firebird versions:
SQL> set stats on;
SQL> select 1 from rdb$database;

CONSTANT
============
1

Current memory = 10135512
Delta memory = 164708
Max memory = 10263380
Elapsed time= 0.11 sec
Buffers = 2048
Reads = 12
Writes 0
Fetches = 157
SQL>

Elapsed time is the time the query needed to complete. Run it a second time and the elapsed time is only 0.02 seconds because metadata is already loaded.

#Lazarus (Free #pascal IDE) 0.9.28 has been released

vsnijders just announced version 0.9.28 of Lazarus on freshmeat.net.

The major changes are as follows:

In this major release, the IDE has many source editor improvements like display
of “double width” fonts (such as Eastern, Japanese, Chinese, and Arabic), better
code folding, highlighting, syncro editing, and persistent blocks. The debugger
has assembler windows, easier exception handling, and breakpoint properties. The
LCL now uses GTK2 as the default widgetset on Linux and BSD and includes the
TMonitor class for multi-monitor support. Refactoring of LCL reduced the minimum
size of executables by about 15%. The support of TFrame support has improved, so
you can visually nest designers in the IDE.

ERP Alternative uses Firebird

DBA Software Inc., a leading provider of manufacturing (MRP) solutions for small business, announced that its decision two years ago to base its flagship product, DBA Manufacturing Next-Generation, on the Firebird™ open-source SQL database has been an unqualified success.

MySQL gets all the publicity when it comes to open-source databases,” said Michael Hart, President of DBA Software, “but based on our experience, Firebird deserves a share of the limelight. MySQL is great for the Internet, but Firebird is perfectly suited for software applications such as our manufacturing package. It has a small footprint, is easy to install, requires no administration, and is fast, stable, and secure.”
