<p>It is up to dbd user modules to use the prepared statements
and document what statements can be specified in httpd.conf,
or to provide their own directives and use <code>ap_dbd_prepare</code>.</p>
<note type="warning"><title>Caveat</title>
When using prepared statements with a MySQL database, it is preferred to set
<code>reconnect</code> to 0 in the connection string as to avoid errors that
arise from the MySQL client reconnecting without properly resetting the
prepared statements. If set to 1, any broken connections will be attempted
fixed, but as mod_dbd is not informed, the prepared statements will be invalidated.
