I am unable to connect to sql server, getting following error.
exception com.microsoft.sqlserver.jdbc.SQLServerException: The TCP/IP connection
to the host SSALES, port 1433 has failed. Error: "The driver received an unexpe
cted pre-login response. Verify the connection properties and check that an inst
ance of SQL Server is running on the host and accepting TCP/IP connections at th
e port. This driver can be used only with SQL Server 2000 or later.".
my local Environment:-
java 5,
sql server enterprise manager version 8,
RunApp.java
Class.forName("com.microsoft.sqlserver.jdbc.SQLServerDriver");
conn = java.sql.DriverManager.getConnection("jdbc:sqlserver://abc;databaseName={db};user=name;password=passworf;");
Statement stmt=conn.createStatement();
ResultSet rs=stmt.executeQuery("SELECT * FROM testdb.testtabel where active = 'a'");
running through cmd:
set path="C:\Program Files\Java\jdk5\bin";
javac -classpath "D:\Web Development\ABC\lib\mail-1.4.3.jar;D:\Web Development\ABC\lib\json-simple.jar;D:\Web Development\ABC\lib\sqljdbc.jar;" com\test\RunApp.java
java -classpath "D:\Web Development\ABC\lib\mail-1.4.3.jar;D:\Web Development\ABC\lib\json-simple.jar;D:\Web Development\ABC\lib\sqljdbc.jar;" com.test.RunApp
Your URL is wrong (see Building the Connection URL), it should be (note the use of an escaped backslash instead of forward slash):
"jdbc:sqlserver://localhost\\SQLEXPRESS;databaseName={db};user=MyUserName;password=MyPassword;"
Also make sure that {db} is replaced with the actual name of the database.
You are trying to connecting by instance name, and some googling on the error message suggests this error can occur if the instance name is wrong or if the SQL Server Browser service is not running. So you need to have the SQL Server Browser service enabled (it is disabled by default).
Otherwise you will need to remove the instance name from the URL, and instead specify the correct port number in the JDBC url (usually 1433, but it can depend on the configuration: double check).
I am new java programmer, I try to setup jdbc connnectivity with wamp mysql server.
Class.forName("com.mysql.jdbc.Driver");
Connection connection = DriverManager.getConnection( "jdbc:mysql://182.73.151.36:3306/sbtsystem?user=sbtuser&password=Pm#dmin&useUnicode=true&characterEncoding=UTF-8");
182.73.151.36 this is server IP address. I can't understand how to connect java with wamp mysql server
Try This:
First run these commands
ping 182.73.151.36
telnet 182.73.151.36 3306
And make 182.73.151.36 mysql eligible for remote connection
After that change your connection line and run this program
Class.forName("com.mysql.jdbc.Driver");
Connection connection = DriverManager.getConnection("jdbc:mysql://182.73.151.36:3306/sbtsystem","sbtuser","Pm#dmin");
You need to first download the jdbc driver files for mysql
(download from here)
The code looks fine. You need to check the network configurations. Try the following commands to see if the server is accessible.
ping 182.73.151.36
telnet 182.73.151.36 3306
supposing your network configuration is correct,
I guess your mysql server on 182.73.151.36 is not configured for remote connection,
I need to connect to Sql Server 2008 from java using jdbc 4.0.
I have a very simple code:
Class.forName("com.microsoft.sqlserver.jdbc.SQLServerDriver");
String connectionUrl = "jdbc:sqlserver://localhost;" +
"integratedSecurity=true;";
Connection con = DriverManager.getConnection(connectionUrl);
But i have this error:
Exception in thread "main" com.microsoft.sqlserver.jdbc.SQLServerException: The TCP/IP connection to the host localhost, port 1433 has failed. Error: "Connection refused: connect. Verify the connection properties. Make sure that an instance of SQL Server is running on the host and accepting TCP/IP connections at the port. Make sure that TCP connections to the port are not blocked by a firewall.".

I follow this answer:https://stackoverflow.com/a/12524566/1554397
I added jdbc4.jar in Libraries/Compile
SQL Server Browser windows service is running.
In SQL Server Network Configuration i selected Enebled on TCP/IP properties.
I Set TCP Address to 1433.
On Run,VM Options i put -Djava.library.path=my path to sqljdbc_auth.dll
And copy in JDk ,in bin sqljdbc_auth.dll.
What should I do?
EDIT:
When write in cmd telnet localhost 1433 i get 'Could not open connection to the host,on port 1433'
If using Window authentication you can do something like:
String url = "jdbc:sqlserver://MYPC\\SQLEXPRESS;databaseName=MYDB;integratedSecurity=true";
Class.forName("com.microsoft.sqlserver.jdbc.SQLServerDriver");
Connection conn = DriverManager.getConnection(url);
and then add the path to sqljdbc_auth.dll as a VM argument (you need sqljdbc4.jar in the build path).
Take a look here for a short step-by-step guide showing how to connect to SQL Server from Java should you need more details. Hope it helps!
In my following programme I am trying to connect MSSQL Server using jdbc in windows authentication. But getting following error

I am using SQL Server in windows authentication mode.
Do I need to do set up other things to connect MSSQL using jdbc in windows authentication.

Using windows authentication:
String url ="jdbc:sqlserver://PC01\inst01;databaseName=DB01;integratedSecurity=true";
Using SQL authentication:
String url ="jdbc:sqlserver://PC01\inst01;databaseName=DB01";
Try following these steps:
Add the integratedSecurity=true to JDBC URL like this:
Url: jdbc:sqlserver://<<Server>>:<<Port>>;databasename=<<DatabaseName>>;integratedsecurity=true
Make sure to add the sqljdbc driver 4 or above version (sqljdbc.jar) in your project build path:
java.sql.DatabaseMetaData metaData = connection.getMetaData();
System.out.println("Driver version:" + metaData.getDriverVersion());
Add the VM argument for your project:
Find the sqljdbc_auth.dll file from DB installed server (C:\Program Files\sqljdbc_4.0\enu\auth\x86), or download from this link.
Place the dll file in your project folder and specify the VM argument like this:
VM Argument: -Djava.library.path="<<DLL File path till folder>>"
NOTE: Check your java version 32/64 bit then add 32/64 bit version dll file accordingly.
You need to add sqljdbc_auth.dll in your C:/windows/System32 folder. You can download it from http://www.microsoft.com/en-us/download/details.aspx?displaylang=en&id=11774 .
From your exception trace, it looks like there is multiple possibility for this problem
1). You have to check that your port "1433" is blocked by firewall or not. If you find that it is blocked then you should have to write "Inbound Rule". It if found in control panel -> windows firewall -> Advance Setting (Option found at Left hand side) -> Inbound Rule.
2). In SQL Server configuration Manager, your TCP/IP protocol will find in disable mode. So, you should have to enable it.
You need to enable the SQL Server TCP/IP Protocol in Sql Server Configuration Manager app. You can see the protocol in SQL Server Network Configuration.
For the current MS SQL JDBC driver (6.4.0) tested under Windows 7 from within DataGrip:
as per documentation on authenticationScheme use fully qualified domain name as host e.g. server.your.domain not just server; the documentation also mentions the possibility to specify serverSpn=MSSQLSvc/fqdn:port#REALM, but I can not provide you with details on how to use this. When specifying a fqdn as host the spn is auto-generated.
set authenticationScheme=JavaKerberos
set integratedSecurity=true
use your unqualified user-name (and password) to log in
As this is using JavaKerberos I would appreciate feedback on whether or not this works from outside Windows. I believe that no .dll is needed, but as I used DataGrip to create the connection I am uncertain; I would also appreciate Feedback on this!
i was getting error as "This driver is not configured for integrated authentication" while authenticating windows users by following jdbc string
jdbc:sqlserver://host:1433;integratedSecurity=true;domain=myDomain
So the updated connection string to make it work is as below.
jdbc:sqlserver://host:1433;authenticationScheme=NTLM;integratedSecurity=true;domain=myDomain
note: username entered was without domain.
If you want to do windows authentication, use the latest MS-JDBC driver and follow the instructions here:
https://msdn.microsoft.com/en-us/library/gg558122(v=sql.110).aspx
You should copy your .dll => here "mssql-jdbc_auth-9.4.0.x64.dll" in that folder => sqljdbc_9.4\enu\auth\x64 to your Java JDK/bin.
Shortly: => sqljdbc_9.4\enu\auth\x64\mssql-jdbc_auth-9.4.0.x64.dll
to Program Files\Java\jdk-16\bin
If it doesnt work, you can open your SQL Server 2019 Configuration Manager -> SQL Server Network Configuration , all protocol's name should be Enabled. After that you should click on (TCP/IP) / IP Addresses, you will see that IPALL-> TCP PORT should be 1433.
After struggling a lot, I finally found a solution, here we go -
Download the file jtds-1.3.1.jar and ntlmauth.dll and save it in Program File -> Java -> JDK -> jre -> bin.
Then use the following code -
String pPSSDBDriverName = "com.microsoft.sqlserver.jdbc.SQLServerDriver";
Class.forName(pPSSDBDriverName);
DriverManager.registerDriver(new com.microsoft.sqlserver.jdbc.SQLServerDriver());
conn = DriverManager.getConnection("jdbc:jtds:sqlserver://<ur_server:port>;UseNTLMv2=true;Domain=AD;Trusted_Connection=yes");
stmt = conn.createStatement();
String sql = " DELETE FROM <data> where <condition>;
stmt.executeUpdate(sql);
Nop, you have a connection error, please check your IP server adress or your firewall.
com.microsoft.sqlserver.jdbc.SQLServerException: The TCP/IP connection to the host localhost, port 1433 has failed. Error: "Connection refused: connect. Verify the connection properties. Make sure that an instance of SQL Server is running on the host and accepting TCP/IP connections at the port. Make sure that TCP connections to the port are not blocked by a firewall.".
ping yourhost (maybe the ping service was blocked, but try anyway).
telnet yourhost 1433 (maybe blocked).
Contact the sysadmin with the results.
I have ubuntu server running on virtual machine locally and I need to connect to mysql database there.
Database is in place and jdbc driver too. The only problem is that only way at the moment for my connection can be something like http://local/phpmyadmin/index.php?db=sandbox and that can't be used in jdbc connection string.
Hope, that somebody can advise a solution.
String url = "jdbc:mysql://localhost:3306/mysql";
Connection con = DriverManager.getConnection(url,"username", "pwd");
Replace localhost with the IP of your VM. You have to use something other than NAT for networking in your VM (like Host-only, internal or bridged assuming VirtualBox).
You probably have to configure your Ubuntu firewall to let the connection through.
Also, you have to set mysql up to accept connections from the outside.
In the file /etc/mysql/my.cnf edit bind-address to your ip:
bind-address = your-vms-ip
