I've installed XAMPP and am running the built in SQL server, but for some reason whenever I try to test the connection of the XAMPP default (test) database through PhpStorm it comes up with an error message of:
The specified database user/password combination is rejected: com.mysql.cj.exceptions.InvalidConnectionAttributeException: The server time zone value 'GMT Summer Time' is unrecognized or represents more than one time zone. You must configure either the server or JDBC driver (via the serverTimezone.
I haven't changed any settings in phpMyAdmin in XAMPP or anything i've left all settings as default. I followed some video tutorials on YouTube and they didn't get this error.
I can create databases and tables fine in phpMyAdmin with no username or password so i'm not sure what the issue is.
Any help will be appreciated
That's a known problem with latest JDBC drivers, see: https://youtrack.jetbrains.com/issue/DBE-7727. Workarounds:
In DataSource configuration window go to Advanced tab and set serverTimezone property to UTC.
Switch DataSource driver to MySQL Connector/J for 5.1 (my version is 5.1.46)
I installed Netbeans IDE 8.2 on Windows 10 and disconnected MySQL 8.0 because I planned to use JDBC, without realizing that the inherent connection was already using it. I now want to reconnect, but after entering all the information into the connect pane it gives me the error "Cannot establish a connection to jdbc:mysql://localhost:3306/mysql using com.mysql.jdbc.Driver (Unable to load authentication plugin 'caching_sha2_password'.)"
Screenshot of error.
Has anyone else had this issue and has someone figured out how to fix it?
The problem does not seem to be with a password as I entered it correctly. Netbeans is "Unable to load authentication plugin 'caching_sha2_password'."
Create a new user with standard security login.
You can use standard Type, SHA256 Password or caching_sha_password.
Also, grant permissions to database that you want to access.
I've had a good search around but not yet found an answer that allows me to rectify this problem.
I'm trying to connect from MS Access to a MySQL 5.2 database on a remote server.
I've set up a user account which has select, insert, update, delete privileges on the table in question. However, when I try to connect with this account, I get:
Connection Failed [HY000][MySQL][ODBC 5.2(w) Driver] Connection using old (pre-4.1.1) authentication protocol refused (client option 'secure_auth' enabled)
When I try to access with the root account, the connection works, which makes me wonder why it's returning an authentication protocol error, since the same driver is being used - all that's changing is the account used - so surely is passing the password via the same authentication protocol? Why would one username/password combination return a protocol error but not another?
It seems this error is very common, but I haven't yet found a response that gives a clear solution. Can you help?
The problem here was due to two concurrent issues.
On the remote server, the global setting OLD_PASSWORDS was set to 1 - meaning that passwords were being hashed in the pre-4.1 method.
the root account had been encoded in the newer hashing method despite the global setting (presumably it had been entered before this parameter was set), meaning that it was being granted access via the ODBC connection because the new hashing was beign recognised.
The global setting caused the PASSWORD() function in MySQL to hash any entered value in the old method instead of the new method as it was supposed to.
I assumed that the DBA had set OLD_PASSWORDS to 1 for a good reason so as a solution I used
Set session old_passwords=0;
set password for 'user'#'%' = password('mypassword');
Using the password() function had not worked previously because the global setting OLD_PASSWORDS=1 caused it to use the same hashing as the OLD_PASSWORD() function. The session setting allowed it to produce the correct password.
"When I installed 5.1.12 instead, I had no problems"
Ditto! Just successfully authenticated into MySQL using ODBC driver version 5.1.12. I have NO idea why MySQL doesn't provide a better way to handle this error w/ its newer drivers, but i can confirm that using ODBC driver 5.1.12 DOES work.
Here is a link to the 5.1.12 ODBC driver installation page.
http://dev.mysql.com/downloads/file.php?id=411741
I was getting the same error message, while my co-worker was not having any problems. I was trying to use MySQL ODBC driver 5.1.13 (the latest GA version available) and she had 5.1.12. When I installed 5.1.12 instead, I had no problems.
Let me begin by saying, I am aware of this thread and others around the web that seek to trouble shoot this issue.
The solutions posted there do not apply to my issue. I have spent 5 hours trying to resolve this before deciding to ask the question.
The problem:
When I attempt to log into SSMS (or connect from a java application) using SQL Authentication I get this error:
A connection was successfully established with the server, but then an
error occurred during the login process. (provider: Shared Memory
Provider, error: 0 - No process is on the other end of the pipe.)
(Microsoft SQL Server, Error: 233)
Although it does work, it is not an option for me to use integreated authentication.
The database I am attempting to connect to is on the same machine as my SSMS instance. There is no network, this is a stand-alone system.
NAMED PIPES is ENABLED in my configuration, I HAVE rebooted since, TCP IP is a higher priority than named pipes in my configuration.
I have even gone as far as to uninstall SQL Server and reinstall it, to no avail.
The details of my SQL Server instance are as follows:
Microsoft SQL Server Management Studio - 10.0.2531.0
Microsoft Analysis Services Client Tools - 10.0.1600.22
Microsoft Data Access Components (MDAC) - 6.1.7601.17514
Microsoft MSXML - 3.0 5.0 6.0
Microsoft Internet Explorer - 9.0.8112.16421
Microsoft .NET Framework - 2.0.50727.5466
Operating System - 6.1.7601
Configuration details are as follows:
http://i45.tinypic.com/vxdz7c.png
http://i45.tinypic.com/vxdz7c.jpg
I connect from java using this code.
Class.forName("com.microsoft.sqlserver.jdbc.SQLServerDriver");
String connectionUrl = "jdbc:sqlserver://localhost;database=AdventureWorks;integratedSecurity=false;User=JIMBO; Password=JIMBO;";
Connection con = DriverManager.getConnection(connectionUrl);
But please remember, this error also occurs when I atttempt to log in to SSMS directly.
Thanks in advance.

To force TCP/IP being used replace localhost with 127.0.0.1 in your connection string.
As you are using a username and password make sure SQL authentication is enabled. By default only Windows integrated is enabled on sqlserver 2008.
With SqlServer authentication keep in mind that a password policy is in place to enforce security.
Forcing the TCP/IP connection (by providing 127.0.0.1 instead of localhost or .) can reveal the real reason for the error. In my case, the database name specified in connection string was incorrect.
So, here is the checklist so far:
Make sure Named Pipe is enabled in configuration manager (don't forget to restart the server).
Make sure SQL Server Authentication (or Mixed Mode) is enabled.
Make sure your user name and password are correct.
Make sure the database you are connecting to exists.
My resolution was to login using the Windows Login then go to security>Logins locate the troubled ID And retype the used password. The restart the services...
Adding "user instance=False" to connection string solved the problem for me.
<connectionStrings>
<add name="NorthwindEntities" connectionString="metadata=res://*/Models.Northwind.csdl|res://*/Models.Northwind.ssdl|res://*/Models.Northwind.msl;provider=System.Data.SqlClient;provider connection string="data source=.\SQLEXPRESS2008R2;attachdbfilename=|DataDirectory|\Northwind.mdf;integrated security=True;user instance=False;multipleactiveresultsets=True;App=EntityFramework"" providerName="System.Data.EntityClient" />
</connectionStrings>
This problem was caused for me by this error which appeared just prior in the application error log.
"A read operation on a large object failed while sending data to the client. A common cause for this is if the application is running in READ UNCOMMITTED isolation level. This connection will be terminated."
I was storing PDFs in a SQL table and when attempting to SELECT from that table it spit out that error, which resulted in the error mentioned in your question.
The solution was to delete the columns that had large amounts of text, in my case Base64 encoded files.
perhaps this comes too late, but still it could be nice to "document it" for others out there.
I received the same error after experimenting and testing with Remote Desktop Services on a MS Server 2012 with MS SQL Server 2012.
During the Remote Desktop Services install one is asked to create a (local) certificate, and so I did. After finishing the test/experiments I removed the Remote Desktop Services. That's when this error appeared (I cannot say whether the error occured during the test with RDS, I don't remember if I used/tried the SQL Connection during the RDS test).
I am not sure how to solve this since the default certificate does not work for me, but the "RDS" certificate does.
BTW, the certificates are found in App: "SQL Server Configuration Manager" -> "SQL Server Network Configuration" -> Right click: "Protocols for " -> Select "Properties" -> Tab "Certificate"
My default SQL Certificate is named: ConfigMgr SQL Server Identification Certificate, has expiration date: 2114-06-09.
Hope this can give a hint to others.

For me it was because only Windows Authentication was enabled. To change security authentication mode. In SQL Server Management Studio Object Explorer, right-click the server, and then click Properties. On the Security page, under Server authentication, select the new server authentication mode, and then click OK.
Change Server Authentication Mode - MSDN - Microsoft

I had the same issue, after multiple trial of suggested solution on this site and others, I found a solution for my scenario. The account was locked out
How to Check if the account is Locked out...
Login to the server using higher privileged account (like SA or admin rights)
Expand security ==> select the login name ==>open the property window of the login ==> select the status page on the property window
Make sure This 3 Things
1, permission to connect database is GRANTED
2, Login is ENABLED
3, Status
SQL server authentication
Login is not locked out (Uncheck the box)
Thanks

I just executed connection.close() by adding it as first statement and it was solved. Then i removed the line.
One follow up to this. I had installed SQL Server 2014 with only Windows Authentication. After enabling Mixed Mode, I couldn't log in with a SQL user and got the same error message as the original poster. I verified that named pipes were enabled but still couldn't log in after several restarts. Using 127.0.0.1 instead of the hostname allowed me to log in, but interestingly, required a password reset prompt on first login:
Once I reset the password the account worked. What's odd, is I specifically disabled password policy and expiration.
Another cause is if the user's default database is unavailable.
I had an account that was used for backing up two databases. When the backup user's default database was taken off-line, the "no process on the other end of the pipe" error started.
Came here looking for a solution to a similar issue, which I just introduced by changing Schannel settings of our IIS server using "IIS Crypto" by Nartac... By disabling the SHA-1 hash, the local SQL Server was not able to be reached anymore, even though I didn't use an encrypted connection (not useful for an ASP.Net site accessing a local SQL Express instance using shared memory).
Thanks Count Zero for pointing me in the right direction :-)
So, lesson learned: do not disable SHA-1 on your IIS server if you have a local SQL Server instance.
For me the issue seems to have been caused by power failure. Restarting the server computer solved it.
Is there a way to set up a ColdFusion data source to connect to a MySQL server over a secure connection using SSL?
I don't see any obvious option to enable a SSL connection on the data source in CF administrator.
The only option I can think of is to use the "connection string" field.
This is for a current configuration that is set up. We have other options, but I am curious as to if this is possible. Thanks.
You would need to use the "other" option in the Drivers dropdown and build your own connection string. Here's an article I found on SSL for MySQL through JDBC drivers: http://www.razorsql.com/articles/mysql_ssl_jdbc.html
UPDATE: Here is another article with information on connecting via SSL and updating the keystore with certificate data. There is also some good content in the comments of the page: http://dev.mysql.com/doc/refman/5.0/en/connector-j-reference-using-ssl.html
