Italian Connessione FireBird

daniweb78 · Apr 9, 2021

Salve a tutti.
Sto provando a collegare la mia app ad un database presente in un pc nella stessa rete.
La mia configurazione è questa nello starter:
-----------------------------------
Sub Process_Globals
Public mysql As JdbcSQL
Private driver As String = "org.firebirdsql.jdbc.FBDriver"
Private jdbcUrl As String = "jdbc:firebirdsql://192.168.1.226:3050/C:\DRSOFTFB\NISI\DBS\ARC\NISI.FDB"
Private Username As String = "SYSDBA"
Private Password As String = "masterkey"
End Sub

Sub Service_Create
'need to disable it as reading from large JdbcResultSet will cause network requests to be sent on the main thread.
DisableStrictMode
End Sub

Sub Service_Start (StartingIntent As Intent)

End Sub

Sub DisableStrictMode
Dim jo As JavaObject
jo.InitializeStatic("android.os.Build.VERSION")
If jo.GetField("SDK_INT") > 9 Then
Dim policy As JavaObject
policy = policy.InitializeNewInstance("android.os.StrictMode.ThreadPolicy.Builder", Null)
policy = policy.RunMethodJO("permitAll", Null).RunMethodJO("build", Null)
Dim sm As JavaObject
sm.InitializeStatic("android.os.StrictMode").RunMethod("setThreadPolicy", Array(policy))
End If
End Sub

Sub Connect As ResumableSub
mysql.Initialize2(driver, jdbcUrl, Username, Password)
Wait For MySQL_Ready (Success As Boolean)
If Success = False Then
Log("Check unfiltered logs for JDBC errors.")
End If
Return Success
End Sub

Sub CloseConnection
mysql.Close
End Sub

Sub ListAnimals As ResumableSub
Wait For (Connect) Complete (Success As Boolean)
If Success Then
Try
Dim sf As Object = mysql.ExecQuery("SELECT CODICE, DESCRIZIONE FROM ART ")
Wait For (sf) mysql_QueryComplete (Success As Boolean, Crsr As JdbcResultSet)
If Success Then
Do While Crsr.NextRow
Log($"codice: ${Crsr.GetInt("codice")}, Name: ${Crsr.GetString("DESCRIZIONE")}"$)
Loop
Crsr.Close
End If
Catch
Success = False
Log(LastException)
End Try
CloseConnection
End If
Return Success
End Sub

Sub Service_TaskRemoved
'This event will be raised when the user removes the app from the recent apps list.
End Sub

quando provo a collegarmi nel db ho questo errore :

vedi tu quale delle due funziona

non trovo nessuna delle due.. hai modo di mandarmele ?
io ho queste:
jaybird-full-4.0.3.java8.jar
jaybird-full-4.0.0.java11.jar

ma non funziona

daniweb78 · Apr 13, 2021

con jaybird-full-4.0.3.java8.jar ho questo errore :

amorosik · Apr 14, 2021

Posta il codice che non funziona
E vediamo di capire il perche'

daniweb78 · Apr 14, 2021

ho messo il progetto in allegato...

amorosik · Apr 14, 2021

Ah, non avevo capito fosse connessione diretta da app Android a db su pc
Pensavo stessi parlando di programma B4j, per il quale ho inviato consiglio precedente
Connessione diretta da app a db non l'ho mai usata, non saprei come aiutarti
Sorry
Ti consiglierei comunque di usare il sistema JRdc2 che assicura migliore protezione dei dati da disconnessioni o simile

Prova questo, qualcuno sembra sia riuscito con il mio codice

Based on @Peter Simpson's code (here), I developed a library that allows you to connect directly to MySql, MsSql (for the moment) databases with B4A and B4J. To be clear, you don't need JRDC to connect to the database located on a server (I am working on a version for b4i, but it is only...

Io ho fatto solo la libreria, non sapevo funzionasse con FireBird che fra l'altro nemmeno conoscevo. Però qualcuno ha provato con i Driver e sembra funzioni. io non ho colpe ne meriti

C'e' poco da fare lo sborone
E' sicuramente un caso fortuito
Adesso il codice e' pubblicato, puoi tranquillamente perdere i sorgenti ???

Non e' UN database
E' un SIOR database server

A ognuno il suo merito, i meriti non si rubano. Il codice è del grande Peter sviluppato per B4J, io ho solo adattato al B4A e ho fatto un involucro (wrap), ma il lavoro sporco lo ha fatto lui.

Le righe istruzioni mettile nei post come 'codice' si capisce meglio
Inoltre non indichi a che riga avviene il problema, vedo un 74 ma non e' univoca l'indicazione, perche' nell'ide vengono numerate anche gli spazi vuoti
Nella select estrai un solo valore
Nelle GetString2 cerchi di leggere anche un secondo campo RS.GetString2(1)
Puo' essere questo il problema?
