Pozdrav!
Instalirao sam si PostgreSQL, VS2012, DBlinq, Npgsql.
Izgenerirao sam dbml:
dbmetal /user=postgres /password=xxxxx /server=localhost:5432 /database=xxxxx /provider=PostgreSql /culture=hr /case=leave /dbml=xxxxxDataContext.dbml
i razrede:
dbmetal /code=xxxxxPGDB.cs xxxxxDataContext.dbml
Kada pokušan napraviti linq query:
xxxxxDC dc = new xxxxxDC(@"server=localhost;database=xxxxx;user=postgres;password=xxxxx;DbLinqProvider=PostgreSql;"); //
if (dc.DatabaseExists())
MessageBox.Show("Jeeeee!");
else
MessageBox.Show("Sranje!");
return;
var q = from r in dc.xxxxx
where r.Naziv.StartsWith("Co")
select r;
dgwArtikli.DataSource = q.ToList();
dobijem exception:
{"A network-related or instance-specific error occurred while establishing a connection to SQL Server. The server was not found or was not accessible. Verify that the instance name is correct and that SQL Server is configured to allow remote connections. (provider: Named Pipes Provider, error: 40 - Could not open a connection to SQL Server)"}
Inner exception:
{"The system cannot find the path specified"}
Uspješno se spajam sa SquirrelSQL klijentom preko JDBC drivera ("jdbc:postgresql://localhost:5432/xxxxx")
Uspješno se spajam na
Trebam li još nešto osim datacontext razreda za spajanje?
Pokušava li se spojiti na SQL Server umjesto postgres baze i ako da - zašto?
Ovo mi je prvi pokušaj linq to sql i odmah sam umjesto SQL servera želio probati sa Postgresom.
