NLog - DDL for Log Table and Setting the ConnectionString Programmatically - asp.net

Question

1:
Is there a create statement for the Database Target Log Table for all the possible fields documented somewhere? I created one by guessing and I could check the source, but it would be handy if the generic SQL was available. I searched StackOverflow and the NLog site, but the SQL I found was dated and contained incorrect field types.
2:
If you're configuring a database target from a nlog.config file, how do you programmatically set the connection string? Something like:
Logger dbLogger = LogManager.GetLogger("dbLogger");
DatabaseTarget t = dbLogger.GetDatabaseTarget;
t.ConnectionString = "...";
in application_start.
Thanks in advance.

Is this below sample helpful to you? I found this in nlog site. Have you tried this?
<target xsi:type="Database" name="db">
<!-- SQL command to be executed for each entry -->
<commandText>INSERT INTO [LogEntries](TimeStamp, Message, Level, Logger) VALUES(getutcdate(), #msg, #level, #logger)</commandText>
<!-- parameters for the command -->
<parameter name="#msg" layout="${message}" />
<parameter name="#level" layout="${level}" />
<parameter name="#logger" layout="${logger}" />
<!-- connection string -->
<dbProvider>System.Data.SqlClient</dbProvider>
<connectionString>server=.\SQLEXPRESS;database=MyLogs;integrated security=sspi</connectionString>
<!-- commands to install database -->
<install-command>
<text>CREATE DATABASE MyLogs</text>
<connectionString>server=.\SQLEXPRESS;database=master;integrated security=sspi</connectionString>
<ignoreFailures>true</ignoreFailures>
</install-command>
<install-command>
<text>
CREATE TABLE LogEntries(
id int primary key not null identity(1,1),
TimeStamp datetime2,
Message nvarchar(max),
level nvarchar(10),
logger nvarchar(128))
</text>
</install-command>
<!-- commands to uninstall database -->
<uninstall-command>
<text>DROP DATABASE MyLogs</text>
<connectionString>server=.\SQLEXPRESS;database=master;integrated security=sspi</connectionString>
<ignoreFailures>true</ignoreFailures>
</uninstall-command>
</target>
