<para>
The <function>maxdb_stmt_execute</function> function executes a query that has been previously
prepared using the <function>maxdb_prepare</function> function represented by the
<parameter>stmt</parameter> resource. When executed any parameter markers which exist will
automatically be replaced with the appropiate data.
</para>
<para>
If the statement is UPDATE, DELETE, or INSERT, the total number of affected rows can be
determined by using the <function>maxdb_stmt_affected_rows</function> function. Likewise,
if the query yields a result set the <function>maxdb_fetch</function> function is used.
</para>
<note>
<para>
When using <function>maxdb_stmt_execute</function>, the <function>maxdb_fetch</function>
function must be used to fetch the data prior to preforming any additional queries.
