Hi: Never mind the dll/udf Statement: SELECT cast (RDB$RELATION_NAME as varchar(32)) AS TABLE_NAME,cast (RDB$INDEX_NAME as varchar(32)) AS INDEX_NAME, RDB$STATISTICS from rdb$indices WHERE rdb$system_flag = 0 order by RDB$STATISTICS rdb$system_flag is 0 for user defind indexes and 1 and greater for system indexes. If I code WHERE 0 = 0 order by RDB$STATISTICS I get everything in result set but with WHERE rdb$system_flag = 0 I get nothing. Why would that be since rdb$system_flag should return 0 or 1 Thanks from out lander. Robert

What optimization advantages are you thinking of? The engine used by Firebird server is identical to Firebird embedded (in Firebird 3 it is even the exact same .so/.dll). The only real difference is that one can accept connections from external processes, and the other can only be used in the same process. Mark

This is an Interbase client tool, not Firebird one. Do you by chance try to
use
Interbase client library to access Firebird server? This is no-go.
Explain:
Not using firebird at all.
Used IB 6 (6.0.2.0) for many years. Old apps D5/BCB5 (hobby).
Installed BCB5 app I did in 2000 on Win10. All worked fine.Went to
githgub and downloaded source for console and decided to put it back
together with enhancements (hobby like model airplanes).
Integrating Planalyzer into IBConsole. 50% there maybe.
Did not have COELESCE() in IB 6 so wrote new UDF to perform function
thus the crash.
As I said in previous post:
Stepped to error block
function TIBTransaction.Call(ErrCode: ISC_STATUS;
RaiseError: Boolean): ISC_STATUS;
var
i: Integer;
begin
result := ErrCode;
for i := 0 to FDatabases.Count - 1 do if FDatabases[i] <> nil then
Databases[i].FCanTimeout := False;
FCanTimeout := False;
{*Handle when the Error is due to a Database disconnect*. Pass it on to
FDatabase so it can handle this}
if CheckStatusVector([isc_lost_db_connection]) then
FDefaultDatabase.Call(ErrCode, RaiseError)
else
if RaiseError and (result > 0) then
IBDataBaseError;
end;
Why it disconnects? Who knows but I will track it down.

I suppose you do some wrong things like: 1. Wrong calling convention – should by „cdecl” not „stdcall” 2. You allocate strings locally and return it to the engine but you should allocate it by „ib_util_malloc”. 3. Your declaration of udf is wrong. 4. You raise some exceptions inside your udf ….. regards, Karol Bieniaszewski

[firebird-support] Re: very slow firebird embedded connection on a web application
May I ask why you are using the embedded version of Firebird for a web application? This version of Firebird does not have the optimization advantages of the server version, even if it is using the same core kernel... Steve Naidamast Sr. Software Engineer
Re: [firebird-support] very slow firebird embedded connection on a web application
just an assumption , but :
basically i have two actions in my test method :
- open the database with the dynamic connectionstring
- run a simple count(*) query on a table that contain 3 rows .
also sometimes i have a Network Error (tcp_error) during my various tests
changes .
and like i said it work fine locally.
btw i have fb 2.5 installed on my local machine , but i stop the service
when i want to test the embedded version .
also on the web application i set the lock destination directory with some
environement variable .
Environment.SetEnvironmentVariable("FIREBIRD", env.ContentRootPath);
Environment.SetEnvironmentVariable("FIREBIRD_LOCK",
Path.Combine(env.ContentRootPath, @"fblock\"));
when i run the web application some empty trace files are created on that
folder , so the embed lib is found but take a long long time to get
data from the database or have a tcp_error message .
can you check if my connectionstring is correct please :
@"Datasource=localhost;initial catalog=h:\fullpath\database.fdb;server
type=1;user id=SYSDBA;character set=UTF8;pooling=False;client
library=h:\fullpath\embed.dll";
(i have tried lot of variants )
the fb version i am using is :
Firebird-2.5.8.27089-0_x64_embed

[firebird-support] udf dll
Hi My udf is not working. Very strange error message. Exciting challenges I execute any old SQL statement and Ok. Run this and not ok. SELECT cast (RDB$RELATION_NAME as varchar(32)) AS TABLE_NAME, cast (RDB$INDEX_NAME as varchar(32)) AS INDEX_NAME, RDB$STATISTICS from rdb$indices WHERE sNullIf( cast( rdb$system_flag as VARCHAR(32) ), cast( 0 as VARCHAR(32) ) ) = 0 order by RDB$STATISTICS This sNullIf( cast( rdb$system_flag as VARCHAR(32) ), cast( 0 as VARCHAR(32) ) ) = 0 is calling my udf dll code: setStatisticsStatement := 'SELECT cast (RDB$RELATION_NAME as varchar(32)) AS TABLE_NAME, ' + 'cast (RDB$INDEX_NAME as varchar(32)) AS INDEX_NAME, ' + 'RDB$STATISTICS from rdb$indices ' + 'WHERE sNullIf( cast( rdb$system_flag as VARCHAR(32) ), cast( 0 as VARCHAR(32) ) ) = 0 order by RDB$STATISTICS'; dmQuery.sqlSetStatistics.SQL.Text := setStatisticsStatement; dmQuery.sqlSetStatistics.ExecQuery; *dmQuery.trxIndices.Commit; <* dmQuery.trxIndices.Active := false; When I click prepare in SQL, no errors. No result in SQL from execute. 2 error messages from execute after prepare Ok. Had to shut down with task manager. Transaction active. I issue commit and it won't shut the process down. Interesting last message. Perhaps commit while long process executing? Stepping through code now. A long process. Any insight based on error messages appreciated.
