osx - Connecting to a remote SQL Server Express 2008 instance on Windows 7 from Java using JDBC (on Mac OS X) -

i'm running issues trying connect remote sql server 2008 express instance java. here specifics:

db server: windows 7 running sql server 2008 express client: mac os x (10.6.8) running java (1.6.0) using jdbc4 drivers

here's code:

import java.sql.connection; import java.sql.drivermanager; import java.sql.sqlexception; public abstract class sqldatabase { protected connection c; protected void establishconnection() { seek { string url = "jdbc:sqlserver://myservername\\sqlexpress;databasename=mydatabase;user=sa;password=pwd"; c = drivermanager.getconnection(url); } grab (sqlexception e) { system.err.println("sqlexception: " + e.getmessage()); } } }

when hits "drivermanager.getconnection" line, throws exception:

the connection host myservername, named instance sqlexpress has failed. error: "java.net.unknownhostexception: myservername". verify server , instance names, check no firewall blocking udp traffic port 1434, , sql server 2005 or later verify sql server browser service running on host.

after extensive google search, here related issues i've resolved , things i've tried:

sql server (on windows 7 db server)

enabled mixed authentication mode on sql instance (http://www.linglom.com/2009/03/28/enable-remote-connection-on-sql-server-2008-express/) ensured sql browser service enabled (http://blogs.msdn.com/b/bethmassi/archive/2008/09/17/enabling-remote-sql-express-2008-network-connections-on-vista.aspx) enabled tcp/ip support explicitly set tcp/ip port 1433 restarted sql server service restarted machine (just measure :) )

firewall settings (on windows 7 db server)

added inbound , outbound exceptions tcp on port 1433 (http://www.sevenforums.com/system-security/58817-remote-access-sql-server-express-2008-windows-7-a.html) added inbound , outbound exceptions udp on port 1434 added inbound , outbound exceptions sqlservr.exe added inbound , outbound exceptions sqlbrowser.exe

jre versions (on os x java server)

tried 1.4, 1.5, , 1.6.0, same result (http://stackoverflow.com/questions/7841411/driver-getconnection-hangs-using-sqlserver-driver-and-java-1-6-0-29)

connection url (in java code)

tried jdbc:sqlserver://myservername/sqlexpress;databasename=mydatabase;user=sa;password=pwd tried jdbc:sqlserver://myservername:1433;databasename=mydatabase;user=sa;password=pwd tried jdbc:sqlserver://myservername:1434;databasename=mydatabase;user=sa;password=pwd tried jdbc:sqlserver://myservername;databasename=mydatabase;user=sa;password=pwd

at point, stumped. there i'm missing, perhaps related running jvm on mac? i'd eternally grateful insights!

How do I check if an insert was successful with MySQLdb in Python? - i have code: cursor = conn.cursor() cursor.execute(("insert new_files (videos_id, filename, " "is_processing) values (%s,%s,1)"), (id, filename)) logging.warn("%d", cursor.rowcount) if (cursor.rowcount == 1): logging.info("inserted values %d, %s", id, filename) else: logging.warn("failed insert values %d, %s", id, filename) cursor.close() fun is, cursor.rowcount always one, though updated database create videos_id unique key. is, insert fails because in tests same videos_id going appear (and when check database, nil inserted). whatever reason, rowcount 1 - logging.warn have spits out rowcount of 1. so, question: can utilize rowcount work out if insert went fine? if so, (presumably) doing wrong? otherwise, how check if insert went fine? your code not commit after modifications (your modifications rolled back). should...
