Nlog Delete SQLite longer than X days - nlog

Question

xsi:type="File" has maxArchiveFiles="5" archiveEvery="Day" properties. Is that possibble to delete db content older than X days?
xsi:type="Database" has rules for that purpose?
My sample Nlog.config;
<?xml version="1.0" encoding="utf-8" ?>
<nlog xmlns="http://www.nlog-project.org/schemas/NLog.xsd"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://www.nlog-project.org/schemas/NLog.xsd NLog.xsd"
autoReload="true"
throwExceptions="false"
throwConfigExceptions="true"
internalLogLevel="Off" internalLogFile="c:\temp\nlog-internal.log">
<targets>
<!--target name="logfile" xsi:type="File" fileName="file.txt" /!-->
<target xsi:type="Database"
name="db"
dbProvider="System.Data.SQLite.SQLiteConnection, System.Data.SQLite"
connectionString="Data Source=log.db3;"
commandType="Text"
commandText="INSERT into Log(Timestamp, Loglevel, Callsite, Message) values(#Timestamp, #Loglevel, #Callsite, #Message)"
>
<parameter name="#Timestamp" layout="${longdate}"/>
<parameter name="#Loglevel" layout="${level:uppercase=true}"/>
<parameter name="#Callsite" layout="${callsite:filename=true}"/>
<parameter name="#Message" layout="${message}"/>
</target>
<target name="colouredConsole" xsi:type="ColoredConsole" useDefaultRowHighlightingRules="false" layout="${longdate}|${pad:padding=5:inner=${level:uppercase=true}}|${message}">
<highlight-row condition="level == LogLevel.Debug" foregroundColor="DarkGray" />
<highlight-row condition="level == LogLevel.Info" foregroundColor="Gray" />
<highlight-row condition="level == LogLevel.Warn" foregroundColor="Yellow" />
<highlight-row condition="level == LogLevel.Error" foregroundColor="Red" />
<highlight-row condition="level == LogLevel.Fatal" foregroundColor="Red" backgroundColor="White" />
</target>
</targets>
<rules>

<logger name="*" minlevel="Debug" maxlevel="Debug" writeTo="colouredConsole" />

How to delete sqlite db content older than 7 days?

Answer 1

Some people suggests EnsureDb(); it works but I want to ask any possibility to set from xsi:type="Database" parameters?
private static void EnsureDb()
{
if (File.Exists("log.db3"))
{
using (SQLiteConnection connection = new SQLiteConnection("Data Source=log.db3"))
using (SQLiteCommand command = new SQLiteCommand(
"DELETE FROM Log WHERE Timestamp <= datetime('now', '-7 day');",
connection))
{
connection.Open();
command.ExecuteNonQuery();
}
return;
}
using (SQLiteConnection connection = new SQLiteConnection("Data Source=log.db3"))
using (SQLiteCommand command = new SQLiteCommand(
"CREATE TABLE Log (Timestamp TEXT, Loglevel TEXT, Callsite TEXT, Message TEXT)",
connection))
{
connection.Open();
command.ExecuteNonQuery();
}
}
