java.sql.SQLFeatureNotSupportedException at org.sqlite.jdbc4.JDBC4PreparedStatement.setNString(JDBC4PreparedStatement.java:36) at org.apache.logging.log4j.core.appender.db.jdbc.JdbcDatabaseManager.writeInternal(JdbcDatabaseManager.java:852)

My JDBC App Test

• PreparedStatement use setString can success write to SQLite
• PreparedStatement use setNString will failed write to SQLite

Log4j2 JdbcDatabaseManager's use of setNString causes writing to SQLIte to fail. Is it possible to use setString for SQLIte instead of setNString?

String sql = "insert into logs (timestamp,loglevel,message,exception,thread) values (?,?,?,?,?)";

		try (Connection conn = DriverManager.getConnection(url)) {
			try (PreparedStatement pstmt = conn.prepareStatement(sql)) {
				// Set the parameters
				Timestamp eventTime = new Timestamp(System.currentTimeMillis());

				pstmt.setTimestamp(1, eventTime);
				pstmt.setString(2, "INFO"); //loglevel
				pstmt.setString(3, "HELLO MSG"); // messag
				pstmt.setString(4, "MY EXCEPTION"); // exception
				pstmt.setString(5, "MY THREAD"); // thread

Sure, since the JDBC driver does not support the optional setNString() method, you just need to set the isUnicode configuration attribute of Column to false (cf. Column plugin reference).

<JDBC name="demo-db-appender" tableName="logs">
  <DriverManager driverClassName="org.sqlite.JDBC"
                 connectionString="jdbc:sqlite:/home/demo/sqlite_data/demologs.db"/>
  <Column name="timestamp" isEventTimestamp="true"/>
  <Column name="loglevel" pattern="%p" isUnicode="false"/>
  <Column name="message" pattern="%m" isUnicode="false"/>
  <Column name="exception" pattern="%ex" isUnicode="false"/>
  <Column name="thread" pattern="%t" isUnicode="false"/>
</JDBC>

Alternatively you can use the ColumnMapping configuration element, which uses setObject():

<JDBC name="demo-db-appender" tableName="logs">
  <DriverManager driverClassName="org.sqlite.JDBC"
                 connectionString="jdbc:sqlite:/home/demo/sqlite_data/demologs.db"/>
  <ColumnMapping name="timestamp" columnType="java.util.Date"/>
  <ColumnMapping name="loglevel" pattern="%p"/>
  <ColumnMapping name="message" pattern="%m"/>
  <ColumnMapping name="exception" pattern="%ex"/>
  <ColumnMapping name="thread" pattern="%t"/>
</JDBC>

I have tested both methods, and they can solve the problem of failed writing to SQLIte.

Thank you for your help and answers
