accesso a database SQL
Ad un server con SQL accedevo tramite ODBC con l'istruzione
oOdbc := TOdbc():New( cDSN, cName, cPass )
e mi tiravo la mia query con:
oDbf := oOdbc:Query(.....)
il responsabile del server dopo un aggiornamento non riesce ad attivare più l'ODBC, di conseguenza non funziona più la mi a procedura.
C'è qualche altro modo per accedervi?
grazie

Re: accesso a database SQL
Sì, via ADO:
EMG
Code: Select all
#define adOpenForwardOnly 0
#define adOpenKeyset 1
#define adOpenDynamic 2
#define adOpenStatic 3
#define adLockReadOnly 1
#define adLockPessimistic 2
#define adLockOptimistic 3
#define adLockBatchOptimistic 4
FUNCTION MAIN()
LOCAL oRs := CREATEOBJECT( "ADODB.Recordset" )
oRs:Open( "SELECT * FROM Clienti ORDER BY Cliente", "Dsn=Clienti;Uid=Userid;Pwd=Password", adOpenForwardOnly, adLockOptimistic )
WHILE !oRs:EOF
? oRs:FIELDS( "Cliente" ):Value
oRs:MoveNext()
ENDDO
oRs:Close()
RETURN NIL

Re: accesso a database SQL
Naturalmente devi mettere il tuo DSN con i corretti userid e password.

HO FATTO:

#define adOpenKeyset 1
#define adOpenDynamic 2
#define adOpenStatic 3
#define adLockReadOnly 1
#define adLockPessimistic 2
#define adLockOptimistic 3
#define adLockBatchOptimistic 4
local cDsn := "cDsn"
Local cName := "cName"
Local cPass := "cPass"
LOCAL oRs := CREATEOBJECT( "ADODB.Recordset" )
oRs:Open( " Select t0.Name, T5.condpag, t0.address, t0.zipcode, t0.fax, t0.city, t0.county "+ ;

"ON T0.KEY = T5.KEY where T0.NAME = 'NOME CLIENTE'", ;
"Dsn=CDsn;Uid=cCname;Pwd=cPass", adOpenForwardOnly, adLockOptimistic )
naturalmente in cDsn c'è il nome del database in cname l'userid e in cpass la password

Re: accesso a database SQL
Per favore, visualizza la seguente stringa e ti renderai conto dell'errore:
? "Dsn=CDsn;Uid=cCname;Pwd=cPass"
EMG
? "Dsn=CDsn;Uid=cCname;Pwd=cPass"

Re: accesso a database SQL
il secondo parametro come errore è:
[ 2] = C Dsn=nomeDB;Uid=utente;Pwd=password
[ 2] = C Dsn=nomeDB;Uid=utente;Pwd=password

Re: accesso a database SQL
Ho visto. Se sei assolutamente certo che sia la query (SELECT etc.) sia Dsn, Uid e Pwd siano corretti allora temo che il database non sia proprio accessibile.

Re: accesso a database SQL
la query è quella che andava bene con l'ODBC e Dsn Uid e Pwd son quelli.... sigh!
