log4net logging error in mysql database logging

i am using log4net for logging in mysql database. log4net configuration is correct and because i have tested to log in sql server and in file but when i'm writing logs in mysql database then it prompt an error to me.
my log4net config is below

i also the

the error i'm encountering is

but actually I'm passing all required parameters dnt know why I'm getting this error.
can anyone guide.

This is a bug in MySql.Data. There isn't a bug report filed for it as far as I know, but you can see from the MySqlConnector integration tests that MySql.Data fails if you call MySqlCommand.Prepare before adding the parameters.
However, that's exactly what AdoNetAppender does. (There is a try/catch block in that code, but that's a recent change, after 2.0.12.)
There are two possible fixes:
Switch to MySqlConnector and change the <connectionType /> to use it.
Add IgnorePrepare=true to your MySql.Data connection string, which will cause Prepare to be a no-op. (Note: this option was removed in 8.0.24.)

As #Bradley Grainger mentioned, MySqlConnector does the job
I sadly cannot comment but #hashimkayani asked for an example, I did try it out and it works perfectly fine:

Log4Net in my .Net website on debugging always shows IsErrorEnabled value as FALSE

I have been trying to log the error in my .Net website to the SQL database using Log4Net AdoNetAppender, but the error message are not getting logged in the database. Looks like the AdoNetAppender is not getting enabled or read. While debugging what I observed is that the Logger.Log shows all its properties values as false. i.e. IsErrorEnabled / IsDebugEnabled / IsFatalEnabled / IsInfoEnabled / IsWarnEnabled all as false.
Version of the log4net.dll I am using is 2.0.8.0

The logging.cs code is as below:
[assembly: log4net.Config.XmlConfigurator(Watch = true)]
namespace Utility.Library
{
public class Logging
{
public static class Logger
{
public static ILog Log = LogManager.GetLogger(typeof(SharedMethods));
}
public static class LogException
{
private static StringBuilder sessionJobLogBuilder = new StringBuilder();
public static void LogError(string sMsg, Exception ex)
{
Logger.Log.Error(sMsg, ex);
sessionJobLogBuilder.AppendLine(sMsg + Environment.NewLine);
sessionJobLogBuilder.AppendLine(ex.ToString() + Environment.NewLine);
}
public static void LogInfo(string sMsg)
{
Logger.Log.Info(sMsg);
sessionJobLogBuilder.AppendLine(sMsg + Environment.NewLine);
}
}
}

But the Logger.Log properties at all levels show as false.

From your comment I read you have a separate app.config file and the Logger class defined in a separate assembly.
An ASP.NET website only considers the web.config file.
Your app.config file doesn't get loaded, so the Log4net configuration doesn't get applied.
One way to solve this is to transform your app.config file into a separate Log4netconfiguration file and to load that explicitly.
Move the <log4net> ... </log4net> content from the app.config file to a separate file (by convention named Log4net.config) in the root of your website project.
The <log4net> element must be the root xml element in that file.
Remove the [assembly: log4net.Config.XmlConfigurator(Watch = true)] from your Logger project.
Add the following code to Application_Start in Global.asax of the website project to ensure that the log4net configuration gets loaded at website startup phase.
void Application_Start(object sender, EventArgs e)
{
ILoggerRepository repository = log4net.LogManager.GetRepository(Assembly.GetExecutingAssembly());
XmlConfigurator.Configure(repository, new FileInfo(Server.MapPath("log4net.config")));
// Remaining startup code.
}
I have the following log4net.config in the root of my website project (near web.config) with just a RollingFileAppender but the concept is the same.
<log4net>
<appender name="file" type="log4net.Appender.RollingFileAppender">
<param name="ImmediateFlush" value="true" />
<file value="Log.log" />
<appendToFile value="true" />
<rollingStyle value="Size" />
<maxSizeRollBackups value="5" />
<maximumFileSize value="10MB" />
<staticLogFileName value="true" />
<layout type="log4net.Layout.PatternLayout">
<conversionPattern value="%date [%thread] %level %logger - %message%newline" />
</layout>
</appender>
<root>
<level value="ERROR" />
<appender-ref ref="file" />
</root>
</log4net>
With your AdoNetAppender setup in my Log4net.config the expected values for IsDebugEnabled, IsErrorEnabled, etc. get shown.
Summary:
Log4net's internal debug logging showed that the configuration file was not being loaded from the presumed location.
The combination of correcting this location (in the XmlConfigurator.Configure method call) and providing a configuration as shown above solved the problem.

log.Debug("Debug message");
log.Warn("Warn message");
log.Error("Error message");
log.Fatal("Fatal message");
but nothing happens :(
Can anyone help me please?

To find the error you can best enable internal debugging in log4net. An error in log4net will not go to your application. You can write it to a log and then see why your logging is not working.
In your app.config:
<?xml version="1.0" encoding="utf-8" ?>
<configuration>
<appSettings>
<add key="log4net.Internal.Debug" value="true"/>
</appSettings>

Log4net FAQ

log4net use a different xml config file when in DEBUG mode compared to RELEASE mode

I have a webapp that I would like to use a different log4net config file when running under DEBUG mode compared to running under RELEASE mode.
I am using log4net version 2.0.3.
In my AssemblyInfo.cs class I have this code:
#if DEBUG
[assembly: log4net.Config.XmlConfigurator(ConfigFile = "log4netDebug.xml", Watch = true)]
#else
[assembly: log4net.Config.XmlConfigurator(ConfigFile = "log4netLive.xml", Watch = true)]
#endif
In my Global.asax.cs class I have this code:
log4net.Config.XmlConfigurator.Configure();
log = LogManager.GetLogger(typeof(GlobalApp));
(log is a public static member of GlobalApp.)
In my log4netDebug.xml file I have this code:
<?xml version="1.0" encoding="utf-8"?>

I have tested this config script and it works if I place it in my web.config file.
The log4netDebug.xml file has the Copy always property set.
When I try to do something like this:
System.IO.FileInfo fi = new System.IO.FileInfo("Log4NetDebug.xml");
log4net.Config.XmlConfigurator.ConfigureAndWatch(fi);
This doesn't work either.
I have read several stackoverflow and other web pages that describe how to do this and I seem to be doing what they recommend doing but it still deson't seem to work.
Any ideas why?

If you look at the Constructor for the FileInfo class, you will see that it expects The fully qualified name of the new file, or the relative file name..
So when you do this System.IO.FileInfo fi = new System.IO.FileInfo("Log4NetDebug.xml"); you need to specify the full path to the file.
As this is in a web app, you probably want something like this:
var logFile = new FileInfo(Path.Combine(HttpRuntime.BinDirectory, "Log4NetDebug.xml"));

It's actually a complete copy of the SQL Server example on the apache page. I've only changed the connection string. The connection itself should work fine, I've tested the connection string with a SqlConnection.
This is how I create the logging object and load the config:
public static class LogFactory
{
public const string Log4NetConfig = "log4net.config";
public static ILog GetLogger()
{
var uri = new Uri(Path.Combine(Path.GetDirectoryName(Assembly.GetExecutingAssembly().CodeBase), Log4NetConfig));
var configFile = new FileInfo(Path.GetFullPath(uri.LocalPath));
XmlConfigurator.ConfigureAndWatch(configFile);
ILog log = LogManager.GetLogger(typeof(LogFactory));
return log;
}
}
Logging itself:
private static readonly ILog Log = LogFactory.GetLogger();
[...]
Log.Info("Test 123");
Logging works fine if I replace the config with my usual "log to file" config, so I guess the error has to be somewhere in the config, but the config is the default example from the homepage.
Can you see an error somewhere?

you did not define when the appender should be used and also with bufferSize you postponed writing to db.
<log4net>
<root>
<level value="ALL" /> <!--send all logs to appenders-->
<appender-ref ref="AdoNetAppender" />
</root>
<appender name="AdoNetAppender" type="log4net.Appender.AdoNetAppender">
<bufferSize value="100" /> <!--THIS WILL POSTPONE DB WRITING UNTIL A BUFFER OF 100 LOG IS REACHED-->
<threshold value="INFO"/> <!--log when >= INFO -->
.....
</appender>
</log4net>
Final thoughts:
You are calling the log4net configurator every time you need a logger and this is not how you should do it.
It should be called only the first time when you start your app (static Main method) or website (global.asax applicationStart).
Then your classes should have the readonly ILog property:
private static ILog logger = LogManager.GetLogger(typeof(MyClass));

<bufferSize value="100" />
This mean that Log4Net will keep 100 records in memory before inserting into the database.
This is by design to limit round trip to the database. Try setting <bufferSize value="1" /> or maybe 0 could work.

While using AdoNetAppender, i am unable to write the log details into the database.
Following are the changes that has been done to make it a workable solution :
1) Use bufferSize value="1" or bufferSize value="0"
2) 'root' directory should be used before all the Appenders that has been used
Eg.
<root>
<level value="ALL"></level>
<appender-ref ref="AdoNetAppender"></appender-ref>
<appender-ref ref="RollingFileAppender"></appender-ref>
</root>
<appender name="RollingFileAppender" type="log4net.Appender.RollingFileAppender">
<file value="mylogfile.txt" />
<layout type="log4net.Layout.PatternLayout">
<conversionPattern value="%date [%thread] %level %logger - %message%newline" />
</layout>
</appender>
<appender name="AdoNetAppender" type="log4net.Appender.AdoNetAppender">
<bufferSize value="1" />
<connectionType value="System.Data.SqlClient.SqlConnection, System.Data, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089"/>
<connectionString value="data source=server_name; initial catalog=database_name;integrated security=false; persist security info=True;User ID=user_id;Password=password" />
