Log4Net AdoNetAppender - Formatting log date to get seconds included - log4net

Question

My issue is that my Database logging does not display seconds (default format seems to be "yyyy-MM-dd hh:mm:00".
Is there any way to change this and get something with seconds at least (miliseconds would be a plus)?
Here is my appender config:
<appender name="AdoNetAppender" type="log4net.Appender.AdoNetAppender">
<bufferSize value="1" />
<connectionType value="System.Data.SqlClient.SqlConnection, System.Data, Version=1.0.3300.0, Culture=neutral, PublicKeyToken=b77a5c561934e089" />
<connectionString value="data source=MyDB;initial catalog=LogSpace;integrated security=True;persist security info=True;Application Name="MyApp "" />
<commandText value="INSERT INTO Log ([Date],[Thread],[Level],[Logger],[Message],[Exception]) VALUES (#log_date, #thread, #log_level, #logger, #message, #exception)" />
<parameter>
<parameterName value="#log_date" />
<dbType value="DateTime" />
<layout type="log4net.Layout.RawTimeStampLayout" />
</parameter>
<parameter>
<parameterName value="#thread" />
<dbType value="String" />
<size value="255" />
<layout type="log4net.Layout.PatternLayout">
<conversionPattern value="%thread" />
</layout>
</parameter>
<parameter>
<parameterName value="#log_level" />
<dbType value="String" />
<size value="50" />
<layout type="log4net.Layout.PatternLayout">
<conversionPattern value="%level" />
</layout>
</parameter>
<parameter>
<parameterName value="#logger" />
<dbType value="String" />
<size value="255" />
<layout type="log4net.Layout.PatternLayout">
<conversionPattern value="%logger" />
</layout>
</parameter>
<parameter>
<parameterName value="#message" />
<dbType value="String" />
<size value="4000" />
<layout type="log4net.Layout.PatternLayout">
<conversionPattern value="%message" />
</layout>
</parameter>
<parameter>
<parameterName value="#exception" />
<dbType value="String" />
<size value="2000" />
<layout type="log4net.Layout.ExceptionLayout" />
</parameter>
</appender>
Thank you for your help!
EDIT: Just as suggested by leppie, I checked my Date type in database, which was smalldatetime. I changed it to datetime and now my logs are as expected (with seconds & milliseconds)

Change #log_date parameter like this:
<parameter>
<parameterName value="#log_date"/>
<dbType value="DateTime"/>
<layout type="log4net.Layout.PatternLayout"
value="%date{yyyy'-'MM'-'dd HH':'mm':'ss'.'fff}"/>
</parameter>
