  109. The JDBCAppender provides for sending log events to a database.
    110. 

  110. 

  111.  <p><b><font color="#FF2222">WARNING: This version of JDBCAppender
    112. 

  112.  is very likely to be completely replaced in the future. Moreoever,
    113. 

  113.  it does not log exceptions</font></b>.
    114. 

  114. 

  115.   <p>Each append call adds to an <code>ArrayList</code> buffer.  When
    116. 

  116.   the buffer is filled each log event is placed in a sql statement
    117. 

  117.   (configurable) and executed.
    118. 

  118. 

  119.   <b>BufferSize</b>, <b>db URL</b>, <b>User</b>, & <b>Password</b> are
    120. 

  120.   configurable options in the standard log4j ways.
    121. 

  121. 

  122.   <p>The <code>setSql(String sql)</code> sets the SQL statement to be
    123. 

  123.   used for logging -- this statement is sent to a
    124. 

  124.   <code>PatternLayout</code> (either created automaticly by the
    125. 

  125.   appender or added by the user).  Therefore by default all the
    126. 

  126.   conversion patterns in <code>PatternLayout</code> can be used
    127. 

  127.   inside of the statement.  (see the test cases for examples)
    128. 

  128. 

  129.   <p>Overriding the <A HREF="../../../../org/apache/log4j/jdbc/JDBCAppender.html#getLogStatement(org.apache.log4j.spi.LoggingEvent)"><CODE>getLogStatement(org.apache.log4j.spi.LoggingEvent)</CODE></A> method allows more
    130. 

  130.   explicit control of the statement used for logging.
    131. 

  131.

  133. 

  134.     <ul>
    135. 

  135. 

  136.     <li>Override <code>getConnection()</code> to pass any connection
    137. 

  137.     you want.  Typically this is used to enable application wide
    138. 

  138.     connection pooling.
    139. 

  139. 

  140.      <li>Override <code>closeConnection(Connection con)</code> -- if
    141. 

  141.      you override getConnection make sure to implement
    142. 

  142.      <code>closeConnection</code> to handle the connection you
    143. 

  143.      generated.  Typically this would return the connection to the
    144. 

  144.      pool it came from.
    145. 

  145. 

  146.      <li>Override <code>getLogStatement(LoggingEvent event)</code> to
    147. 

  147.      produce specialized or dynamic statements. The default uses the
    148. 

  148.      sql option value.
