[firebird-support] Executing isql without server running
If you need be shure that no one connect to your DB whe you do your maintenance - use 'shutdown database' technique. I will just start my server process then. Just thought I could do the DB patching in a kind of maintenance mode using isql directly.
[firebird-support] Executing isql without server running
In FB 2.5 you need 'embed' version of client dll. Download archive with 'embed' version. Unpack into empty dir. Rename 'fbembed.dll' to 'fbclient.dll'. Copy isql.exe into that dir and try. For FB 3.0 may need some config in 'firebird.conf'. Possibly need enabling 'embedded provider'. In all cases must be no other connections to that DB and DB must can be accessed locally in file system. 29 січня 2020, 13:01:21, від "Matthias Winkler spmm...@gmail.com [firebird-support]" : Hi, I thought there was a way to work on a fdb file with just isql and without the firebird process running. But I cannot find the syntax anymore. If I just give a path /path/to/db.fdb I still get an error saying "cannot connect to localhost -902" Any ideas?
[firebird-support] Identity vs Before Insert Trigger
As i understand your question - yes. BI trigger fired before column constraints check. To allow you process and correct row to store without errors. Execution sequence: BI trigger -> default values -> not null -, FK-, check- constraints -> record storing -> AI triggers. However, the same query works without issue with a before-insert trigger using a generator. My question - is this intended behavior? Or a bug in the identity implementation? -- Daniel
[firebird-support] Identity vs Before Insert Trigger
For my previous message: and if you do not correct 'null' value in BI trigger, next you get an 'validation error'.
[firebird-support] Migrating from 1.56 to FB 3 - making good progress
The trick is populating the 3.0 database. I know there are data pump tools out there but they seem to be old? Use "Extract Metadata" feauture of IBExpert with table data extraction My question: Now that my 1.56 metadata script works w/out error with the 3.0 database, can I simply backup the 1.56 database and restore under FB 3? Try. If does not work - migrate to FB 2.0 using corresponding tutorial (if any), then to FB 2.5.9, then to FB 3. E.g., backup DB with FB 1.5 -> restore with FB 2.0 -> backup with FB 2.0 -> restore with FB 2.5 -> backup with FB 2.5 -> restore with FB 3 At least 2.5 to 3.0 works perfect. Just download archives with required versions of FB (you need 'bin' directory with gbak.exe), and create bat-script with commands.
[firebird-support]using parameters with EVENT firebird 2.5+
I am also looking for somthing like that. Typical task - inform clients about
changes in some records: client need an record ID.
It's hardly compatible with the existing events architecture and API, so
I'm still somewhat sceptical about its implementation.
Dmitry
I don't now API details, but my idea: what if we can specify 'mask' in Event
name on clients, e.g. "ORDER_CHANGED*"?
Then client subscribes to event "ORDER_CHANGED*", and his code receive all
events, who name is starting with "ORDER_CHANGED".
On DB side in trigger we can fire event like that:
post_event('ORDER_CHANGED' || new.ID)
In client's code he get an actual event name, like ' ORDER_CHANGED'. Then
he can parse received string as he need.
[firebird-support] "could not convert variant of type (null) into type (currency)"
If your client app written in Delphi, there is bad usage of Variant type in your code (or external components). Absent one of checks when converting Variant to Currency, e.g.: procedure TForm1.Button1Click(Sender: TObject); var C: Currency; V: Variant; begin V := 10; C := V; // Works Edit1.Text := FloatToStr(C); V := Null; C := V; // Error Edit1.Text := FloatToStr(C); V := Null; // Correct usage if VarIsNull(V) then C := 0 else C := V; Edit1.Text := FloatToStr(C); end;

[firebird-support] Connecting to database on remote server
Read here about connection strings:
https://firebirdsql.org/file/documentation/reference_manuals/user_manuals/html/qsg3-databases.html
Run "Command prompt" and enter command:
>ping FIREBIRDSERVER
If 'ping' command failed - use an IP address instead:
>ping xxx.xxx.xxx.xxx
If succeeded - use IP instead 'FIREBIRDSERVER' in connection string
Additionally. As I understand, your Firebird server is installed on Windows
('FIREBIRDSERVER').
By default "Windows Firewall" blocks incoming connections from network.
Open 'Windows Firewall', create 'inbound' rule to allow connections to TCP port
3050 from LAN.

[firebird-support] FB 2.1 transaction question
Sometimes our application works from remote place via VPN over wireless Internet connection. Often connections brakes and we have active DB connections in MON$ATTACHMENTS for a long time and their TA's blocks further work. Is this same case as in your reply? At least we receive an errors in 'unique' indexes - we use artificial counters in special table to generate sequential document numbers for each employee. So, when employee reconnect to continue his work - he can't create new document: TA, who was increase this counter, was broken and was not committed, so new document watch an old counter, and gets an already used next counter value. But previous document in broken TA, that uses his next counter value, was inserted in respective table and his number is already in unique index (but invisible for new TA's). This belongs not only for counters. E.g., we create a customer with unique short name, and when we reconnect after connection lose - we can't re-create customer with this short name, until broken connection will closed. Firebird version: 2.5.8. For such extremal cases your application can present for SYSDBA special window that shows table with data from MON$ATTACHMENTS (login, connection's start date, client IP, app name). Deleting record from MON$ATTACHMENTS will close connection, so you can continue. Again, only necessary in the case where the connection remains active while the transaction is stalled. _._,___
[firebird-support] FB 2.1 transaction question
Important notice: modified rows in that 'dead' transaction remains locked along
this TA existence. So, your another connections will get 'lock conflict' errors
('no wait' TA's), or waiting forever ('wait' TA's) when try to modify same
rows. Even if you just want reconnect on unexpected connection lose and finish
your previous work.
For such extremal cases your application can present for SYSDBA special window
that shows table with data from MON$ATTACHMENTS (login, connection's start
date, client IP, app name).
Deleting record from MON$ATTACHMENTS will close connection, so you can continue.
The data isn't committed, so it isn't visible to any other transaction.
If a connection is closed with an active transaction, the transaction
will eventually be rolled back by Firebird. See also "“Dead”
transactions" in the Firebird book.

To do this you must follow this steps (for FB 2.5): - grant role RDB$ADMIN to user in your working DB - user must login with RDB$ADMIN role into your DB. After that he can access MON$ATTACHMENTS. Hi, how can i grant select on MON$Attachements to normal user that he/she can see all attachements not only self? I use Firebird 3. regards, Karol Bieniaszewski
