firebird2.5

I am extending the data layer of an existing application to work with Firebird 2.5, in addition to MSSQL and SQLite, but I have hit a stumbling block. I have a field called TimeStamp which stores the data/time as type TimeStamp. This works fine under MSSQL and SQLite where the type is datetime, but falls over under Firebird. The following SQL: SELECT SysTrnId,'TimeStamp' from "TRANSACTIONS" seemingly works, but the TimeStamp field is return as fieldname "CONSTANT" and the contents are the text "timestamp" Is it possible to do this under Firebird, or am I going to have to rename the field and

I'm using Firebird Embedded v2.5. How to use procedures in query (SELECT) ?

I've installed Firebird-Server 2.5 on FreeBsd 9.1 using: pkg install firebird-server-2.5.2_1 It's working ok, since I can connect using FlameRobin from an external PC. Now, when I try to restore a database using gbak, I got this: ... gbak: ERROR: CHARACTER SET WIN1252 is not installed gbak:Exiting before completion due to errors Should I install something more server side?. The database was created on a Windows machine, that's why its character set is WIN1252. EDIT: after some trouble I deinstalled firebird and reinstalled WITHOUT USING SUDO. Now I can connect using isql-fb and do "show system

I want the Firebird backup tool gbak to write its output to a Delphi stream (with no intermediate file). There is a command line parameter to write to stdout rather than a file. I then use the Execute method in JEDI's JclSysUtils to launch gbak and process that output. It looks like this: procedure DoBackup; var LBackupAbortFlag: Boolean; LBackupStream: TStringStream; begin LBackupAbortFlag := False; LBackupStream := TStringStream.Create; try Execute('"C:\path to\gbak.exe" -b -t -v -user SYSDBA -pas "pw" <db> stdout', LBackupStream.WriteString, // Should process stdout (backup) SomeMemo.Lines

I want to return the error message from a procedure when an exception happens. In SQL Server you would select the Error_Number() and Error_Message(). How would I do it in FirebirdSql SET TERM ^ ; CREATE PROCEDURE sprocname ( id int ) RETURNS ( gcode int, errmsg varchar(250) ) AS BEGIN gcode = 0; errmsg = ''; -- do procedure code here WHEN ANY DO BEGIN gcode = gdscode; -- ?? errmsg = ??; END SUSPEND; END^ SET TERM ; ^ Unfortunately you will need to do that at the client side, as it is currently not possible to obtain this in PSQL. There is a feature request in the Firebird tracker, which has
